Majin Buu/Djinn-Boo (魔人ブウ, Majin Bū)
Voiced by (Japanese): Kōzō Shioya — All Forms
Voiced by (Latin American Spanish): Mario Sauret (Z, GT and Battle of Gods), Marcos Patiño (Kai The Final Chapters and Super) — All Forms

The final villain of the Z saga, a pink, amorphous magical creature summoned by the alien Evil Sorceror Bibidi to defeat the Kais and thus to take over the universe. When he absorbed the Grand Supreme Kai, though, said Kai's overwhelming goodness weakened Buu's power and made him more childlike and misguided rather than the feral and omnicidal being he originally was. Eventually, Buu was sealed away, then awakened by Babidi, Bibidi's doppelganger, many, many years later. The two work together for a time, but Buu eventually gets tired of Babidi's criticism and kills him before going on a rampage of his own. Mr. Satan, who initially was sent to kill him, against all odds befriends Buu. But an unfortunate incident releases the true evil side of Buu as a Literal Split Personality, and it all goes downhill from there until he eventually reverts to his original and much more insane form. After blowing up the earth, Buu tears around the afterlife until a final battle between him, his Good Counterpart Fat Buu, Goku, and Vegeta commences. After some back and forth, Goku manages to obliterate him using power donated by all the citizens of Earth focused into one Spirit Bomb. But rather than be completely destroyed, he is reincarnated at Goku's wish as the human Uub who becomes Goku's pupil at the end of the series, while his surviving good side, Fat Buu, goes on to live with Hercule on Earth.

Each of Buu's forms is effectively a different character with different abilities and personalities. They are each described below.

To read about them all in Fat Buu's voice here.

    open/close all folders 

  • Achilles' Heel: Buu's regeneration is utterly ridiculous. But it does have one drawback- while he's regenerating from being blown apart, his disembodied pieces are defenseless. It was outright stated that even Piccolo could've completely wiped the disembodied pieces of Super Buu from existence in the Hyperbolic Time Chamber despite being orders of magnitude weaker than he,note  and demonstrated in anime filler (for what it's worth) that SS2 Vegeta and Goku can do the same. For opponents near or above his ki power, they don't even need to blow him apart first; Vegito completely erased a piece of Gohan-Buu from existence with a small kiai and both Goku and Gotenks were stated to be capable of completely wiping out Kid Buu and Super Buu respectively with Kamehamehas at full power.note  The key seems to be to keep relentlessly attacking and never give him a break, because if you do, he'll be good as new in seconds.
    • Buu's absorption technique has the same drawback. Again, the pieces he detaches from himself are remarkably easy to get rid of, as Vegito demonstrates when he erases Buu's detached head tentacle. This is why every time Buu does absorb someone, he has to plan it out ahead of time and distract his opponent, so the piece can take them off guard.
    • Buu's absorption technique also has another weakness regarding the above. He can successfully absorb a target if they are taken off-guard, but as Vegito demonstrates, if you're fully prepared it is possible to avoid complete absorption by shielding yourself in a Ki Barrier just in time. Doing this will allow the shrunken target to infiltrate Buu's body and free any absorbed victims in the process.
  • Adaptational Wimp: Part of what made him so hard to kill is that he can regenerate from a single molecule. In all video games, for gameplay reasons, he doesn't need to be that level of dead to die.
  • Alien Blood: He bleeds purple.
  • Ambiguous Situation:
    • Exactly how much knowledge and personality Buu gains from those he absorbs is ambiguous. On one hand, Super Buu mentions that he would gain Piccolo's "brain" when absorbing him, and he does indeed seem to gain additional knowledge after doing so (including memories of him training Gohan, though this is filler and not in the manga, and it contradicts that Super Buu doesn't recognize Dende in the manga after he heals Gohan), but on the other Fat Buu is remarkably dimwitted for having absorbed two intelligent gods. Adding to the ambiguity, while it's heavily implied that Fat Buu and Super Buu have their personalities modeled on twisted versions of the Grand Supreme Kai and South Supreme Kai respectively (as the pure, original Buu is little more than an animal, and those two Buus most resemble those two Kais respectively in body type), we don't know what either of them were like originally beyond the barest impression given by a filler flashback. How much of Super Buu and Fat Buu are the Kais, and how much of them are just Kid Buu's original personality with additional brain processing power added? The Super manga gives more credence to the idea that Fat Buu's personality was partially modeled on the Grand Supreme Kai's when Shin notes that he was a lax person and not very smart.
      • At the very least, we know that the fused Buus have all the knowledge of their previous incarnations, as both Fat Buu and Super Buu know what their bodies are going through during transformations, and Super Buu recalls having met Gohan and Goku when he was still Fat Buu.
    • Whether Super Buu knew who Beerus was due to having the Kais inside him is also interesting to ponder (it's not like he'd have a reason to tell anyone if he did). On the one hand, Fat Buu didn't know who Beerus was, hinting that Majin Buu, in general, lacked that information. On the other, Super Buu was shown to possess knowledge that Fat Buu didn't, such as how to sense ki, so it's not implausible that his nature as a Superpowered Evil Side lets him access additional memories on top of additional power. Supporting this is that Elder Kai said that Buu would absorb Kibito Kai if he found him (while he seemed happy to just kill Goku, who is stronger), hinting that Buu did take a special interest in the Kais for whatever reason and that he would make his way to the World of the Kais after dealing with Gohan and Goku. If he did know, then his Near-Villain Victory would look more deliberate on his part since at the time he knows where Old Kai and Kibito Kai are (he had Gohan's memories by then), and would know that Beerus shares a life-link with them.
    • Whether Goku could have actually beaten Fat Buu and ended Buu's whole arc prematurely. He says he could have, but immediately after doing so, he then claims that he can beat Kid Buu as well, only to fail due to underestimating Super Saiyan 3's power drain. This is notably the second time in the arc where this form fails because of stamina loss.note  Also, we see that Fat Buu can reasonably keep pace with Super Saiyan 3 Goku (neither were taking the fight very seriously, but Goku was still sweating bullets by the end of it) and Kid Buu, on top of being a Stone Wall of epic proportions thanks to his Healing Factor (Beerus needs to hit him several times to keep him down, after one-shotting Goku with a karate chop). So it's plausible that he could simply have outlasted Goku in a fight the same way the other two Buus did. But we never do see them fight each other with lethal intent.
  • Ancient Evil: Even before his origin was changed, he was ancient. With the reveal, he's one of the single most ancient entities in Dragon Ball, being billions of years old.
  • Angels, Devils and Squid: Majin Buu is the Squid to Shin's Angel and Dabra's Devil. While the latter two preside over their dimensions of light and darkness respectively and instill some semblance of order, Majin Buu just rampages throughout the cosmos leaving death and destruction in his wake while defying logic at every turn.
  • Antagonist Abilities: On paper, Buu is pretty much a perfect fighting opponent. In addition to his extremely high power and energy levels, he has other abilities that make defeating him near-impossible. He can copy any ability he sees, he can absorb other people to grow stronger, he can split himself into new forms and grow stronger by culling his own weaknesses, he can take any shape he can think of and stretch/increase his size and mass, and in addition to being almost impossible to damage in the first place, he can regenerate back to full strength within seconds if a small part of himself survives. Even worse, he has a pretty much Unblockable Attack that transforms anything into anything else he chooses, which can't be stopped even if you're stronger than he (although, Vegito does manage to still put up a fight after being transformed). The only true way to defeat him is through enough raw energy to destroy every trace of him, down to the smallest particle.
  • Apocalypse How: According to the Supreme Kai, Fat Buu and Kid Buu inflicted at least multiple versions of a Class X-2. The anime, which actually shows some of the rampages, clarifies this as a Class X-3, showing an entire galaxy being stripped of its stars (and presumable planets with them) over the course of some years. Super Buu at his strongest nearly causes a Class X-4 with his universe-destroying Vice Shout, and it is stated that any version of Buu would eventually cause a Class X-4 if left to rampage for long enough.
  • Arch-Enemy:
    • To Shin the Supreme Kai, who holds the most hatred towards Majin Buu and has the most personal connection than any other character. Buu murdered/absorbed all of his mentors and friends during his first rampage a few millennia ago. Ever since, Supreme Kai has dedicated all of his efforts to prevent Buu from ever being released again, and feels directly responsible when he fails.
    • To Goten and Trunks, as well as Gotenks, who was created specifically to be an opponent for Buu. The boys trained endlessly to match Buu, angry at him for killing Vegeta, Gohan (who they mistakenly believed was dead at the time), and Chi-Chi (who Goten saw Buu murder right in front of his eyes). Things escalate 100-fold when Buu eats all of their friends and family on the Lookout while they were trapped in the Hyperbolic Time Chamber. From this point on Gotenks stops messing around and becomes determined to make Buu pay. Similarly, Buu recognizes (Super Saiyan 3) Gotenks as the first opponent who could actually prove a threat to him with Piccolo noticing the monster has now gotten serious.
    • To Goku, who was brought back to life to fight against Buu after he killed all of Goku's friends and family. And eventually blew up the Earth and many planets. While Fat Buu turned good, it was Super Buu and then Kid Buu that really got under Goku's skin. Before killing him, Goku wished for Kid Buu to be reborn as a good guy so they can have a good, clean fight; and 10 years later, Kid Buu was reincarnated to Uub and eventually became Goku's apprentice.
    • To Vegito. Much like Gotenks, he was born for the sole purpose of facing Buu, after the monster killed/absorbed all of his family and friends. Vegito is also the one opponent who Buu has never been able to beat, and completely dominates Buu. As a result, Buu hates Vegito with a burning passion.
  • Artificial Human: His original backstory, as said by the Supreme Kai, is that Buu was created by Bibidi in order to sow chaos across the universe. His revised backstory makes this no longer the case, but he's still clearly artificial in nature.
  • Arc Villain: After he kills Babidi he becomes a menacing villain on his own.
  • The Assimilator: Buu's defining trait as a villain. Once he encounters a stronger opponent he absorbs them into himself, adding their power to his and taking on their abilities, their knowledge, memories and even certain aspects of their identity. This can make for a very unnerving fight (as Gohan finds once Buu absorbs his old mentor Piccolo), but can also work to the heroes' advantage (Buu became much less malevolent and dangerous, and lost some of his raw power when the original Buu absorbed the peaceful, benevolent Grand Supreme Kai, becoming Fat Buu). Like Cell before him, Buu has two methods for doing this: the first, which is how he absorbs Gohan, Gotenks and Piccolo is simply using a severed part of his body to completely engulf the victim, and then having that chunk of Buu-goo remerge with him. The second method (which is how Evil Buu absorbs Good Buu) is turning the victim into a piece of candy and eating them.
  • Assimilation Backfire: As noted, absorbing the benevolent Grand Supreme Kai severely handicapped him thanks to the Kai's inherent goodness. Also when Super Buu absorbs Gotenks, he becomes much more powerful, but when Gotenks's Fusion Dance wears off after its 30-minute time limit, Super Buu reverts as well, once again becoming weaker than Ultimate Gohan.
  • Awesomeness by Analysis: Buu's actually smarter than he seems. He can instantly and instinctively master attacks after seeing them done once. Heck, he instantly pulled off a pretty impressive Kamehameha in the same fight with Goku that introduced him to it (put things into perspective, Goku's a martial arts genius, and his first Kamehameha was hardly strong enough to dent a car). This ability even extends to his human reincarnation Uub, who learns to keep up with Goku in a fight while fighting him for the first time.
  • Ax-Crazy: All his forms, taken to Omnicidal Maniac extremes. Every time he transforms into a new form, he becomes progressively more evil and psychopathic. When he got to his "final", original form, he was at the point where he just blows up planets without a second thought. While his Power Level as Kid Buu is the subject of much debate among Dragon Ball fans, everyone can agree that said form was definitely the most insane. To put it in perspective, the first thing he did after reverting to Kid Buu was to try and blow up the planet he is on. When he was foiled, he just made the next shot ten times bigger just so he wouldn't miss.
  • Berserk Button:
    • Taking away his sweets is a universal one for Buu, regardless of which version you're doing it to.
    • For at least two of his three incarnations: calling him stupid. Dabura, Babidi, and Vegeta angered Fat Buu by calling him a "moron" and "idiot", while Gohan caused Super Buu to fly into a rage when he called him a "retard." They all came to regret it.
    • Damaging him badly is another. Fat Buu gets pissed off and angrily releases a large ki blast after Vegeta impales him with a ki beam, noting that it "hurt a bit". Super Buu is just as pissed off after getting hit with Gotenks' "Continuous Die Die Missiles", with Piccolo noting that he's been shaken up by fighting someone so close to his own strength for the first time; and as he's getting beaten down by Vegito, he resorts to increasingly desperate tactics to try and defeat him- including getting pissed off enough to collapse the wall between dimensions completely. Lastly, at one point Super Saiyan 3 Goku blows up Kid Buu badly enough to make him regenerate wrong, and Buu has an annoyed look on his face after Goku makes a snarky remark in response.
  • Beware the Silly Ones: Yes, Buu looks like pink chewing gum, is obsessed with sweets, and is the most childish villain in the series. He is also one of the most dangerous creatures in existence and was the undisputed strongest being in the universe for billions of years (not counting Beerus and Whis, that is.) At his worst, he could destroy galaxies in under an hour.
  • Big Bad: The final one for the manga and Z anime. Fat Buu did become good, while his other forms Super Buu and Kid Buu take on the role. Buu's story, including the introduction with No Antagonist and the sections where Babidi is an Arc Villain trying to summon him, is by far the single longest single arc in all of Dragon Ball- lasting a whopping 7 volumes (98 chapters) in the manga and 96 episodes in the original anime (69 in Kai).
  • Bishōnen Line: In a very convoluted example, that both plays it straight and inverts it. From the straight angle- Kid Buu is a small, black sclera/red iris-eyed child-like being with crazed animalistic behavior, wearing only pants/boots, his Ultra Buu form is far larger/bulkier version of the first form- acting like a savage, animalistic brute. his Fat Buu form is drastically different in shape- being more cartoonishly obese with yellow gloves/purple cape/yellow boots/black leggings/puffy pants, a capacity to think/speak like a child-like being, and closed eyes that change the red iris/black sclera for black iris/white sclera like most living beings. Evil Buu- a gray-skinned, lankier form wearing the Fat Buu outfit, but with black sclera eyes with white irises, and more advanced vocabulary. Super Buu is an adult-looking version of the Kid Buu form, but with limited vocabulary, facial mannerisms, and mitten-like fingers in the manga. His Gotenks/Piccolo/Gohan absorptions lead to the pinnacle of his power- with a more humanoid face, an eventual chin, a more human-like physique, and is able to speak eloquently. He then inverts this as his absorptions are removed- going to regular yet larger Super Buu, bulkier Ultra Buu, and finally Kid Buu- playing it straight from a visual standpoint, but inverting it as it's his original form. And if one counts Uub as an extension of the evolution, it's played at its most straight- with him being essentially a human compared to the pink/gray-skinned humanoids he was previously.
  • Bizarre Alien Biology: Buu is basically a pink, gelatinous mass, presumably magical in nature, that naturally structures itself in the form of a humanoid. He can manipulate his body in various ways, allowing for regeneration, shapeshifting, stretching limbs, etc., but he rarely reverts to an actual blob form. When he does, it's mostly to envelop and absorb people into his body, which is shown to contain its own interior pocket dimension, as seen when Vegito is absorbed inside of it and rescues the other Z Fighters that Super Buu had absorbed. In GT, Buu's unique physiology allows him and Mr. Satan to avoid being possessed by Baby's mind-controlling eggs (Buu by simply ejecting it from his body, and Mr. Satan by hiding inside of Buu).
    • A subtle element of his biology that not many notice at a first glance- his head tentacle's default length is directly proportionate to his strength. Fat Buu and Kid Buu both have very small head tentacles. Base Super Buu has a head tentacle that's much longer in both absolute terms (as Super Buu is around twice Kid Buu's height) and relative terms, reaching past his shoulders to his upper back. The form Buu took after absorbing the Southern Supreme Kai, which is acknowledged as stronger than base Super Buu, has a head tentacle that stops at his waist. Finally, the head tentacle on Gotenks-Buu goes past his knees while Gohan-Buu's is slightly longer than even that and almost reaches his feet. This extends to Super, as after Good Buu trains for a couple hours, his tentacle gets longer.
    • Given his preferred diet and certain comments he makes that hint he's unable to digest meat, it's likely his biology is sugar-based rather than protein-based like life as we know it.
  • Black Eyes of Crazy: All his forms except Fat Buu.
  • "Blind Idiot" Translation: Two major cases of this were responsible for much of the confusion on which of Buu's forms was the strongest.
    • One, the anime (both original and the various dubs), as well as an early fan-made English translation of the manga, has Old Kai stating that absorbing the Grand Supreme Kai and South Supreme Kai "weakened" Buu when the original manga's text was more about them making him docile. The official Viz English translation of the manga fixes this: instead, Old Kai says "so the souls he ate tamed him", with no reference to power.
    • Two, when Buu returns to his pure, original form (Kid Buu), Kibito Kai tells Old Kai the story of his origin. After this, Old Kai asks if the Buu standing before them is the "original, most troublesome Buu", and Kibito Kai confirms that it is. The anime, as well as some non-English translations of the manga, change that to "the original, most powerful Buu", or the "original, most dangerous Buu." While the latter is more accurate than the first, both are incorrect. The exact word used is 厄介/yakkai, which literally means troublesome, bothersome, burdensome, annoying, or tiresome. As in, the one who caused the most trouble/burden/annoyance/etc. Considering the exact wording and context, this is much more likely to be a reference to the fact that this form of Buu, as the original incarnation, is the form Buu was in during most of his initial rampage millions of years ago (including when he disrupted the cosmic order by killing several gods), rather than being any reference to how strong or dangerous he is.
  • Blood Knight: As Super Buu and to a lesser extent Fat Buu. The desire to fight strong warriors was the only thing keeping them from destroying the Earth outright. As for Kid Buu, he just didn't care. That's not to say Kid Buu didn't have the desire to fight strong warriors, just that it no longer conflicted with his desire to destroy everything else.
  • Book Dumb: Every incarnation of Buu lacks common sense and knowledge. Fat Buu needs explanations on some unusual terms, while Super Buu doesn't know what a minute is.
  • Born Winner: He's a Superpower Lottery Winner like no other in the series. He can regenerate from vapors, learn techniques from just seeing them once, and can become stronger by absorbing other people. It takes the energy of an entire planet with billions of people and a wish on the Dragon Balls to put him down.
  • Bouncing Battler: Majin Buu becomes this when he performs his ball attack.
  • Breath Weapon: As Fat Buu demonstrates, he can exhale a magic/ki-based blast of energy capable of vaporizing a city.
  • The Brute: Unlike Frieza or Cell, he is merely a force of brute strength, who uses little brain power and is quick to anger. As Super Buu, his desire to fight a strong enemy leads to some staggering feats of impatience, but also displayed surprising cunning. Though, Buu is a quick learner and adopts his enemies' techniques after watching them once or absorbing them.
  • Challenge Seeker: All forms of Majin Buu are this to some extent. Fat Buu doesn't destroy the Earth because Goku promised him a challenging fight in three days. Super Buu demands the challenger sooner and keeps Gohan around after absorbing Gotenks and Piccolo so he can test his new power. Kid Buu fights Goku, Vegeta, and Fat Buu instead of nuking the planet as he did to the Earth because he was having fun fighting them.
  • Combo Platter Powers: Buu has several sets of Story Breaker Powers that make him close to invincible. He can regenerate from vapors, which completely blows Cell's regeneration out of the water, can grow stronger from absorbing other people, taking their power and techniques into his own being, and has a beam that can change objects or people into anything he chooses. This is on top of him being extremely powerful and he was the strongest thing in existence for billions of years.
  • Combat Sadomasochist: For whatever reason, Buu enjoys being hit by attacks, trusting in his Healing Factor to let him shrug off whatever damage anybody inflicts on him. This is made most explicit when Fat Buu fights Basil in the Super Universe Tournament, where he spends the first minute or so of the fight letting Basil beat him up without even trying to fight back before laughing it off, literally describing it as playing in the subbed version. He continues to let Basil pummel him afterward... until Mr. Satan gets hurt. Then Buu's not in a playing mood anymore.
  • Confusion Fu: All the Buu's implement this to some degree, whether it be manipulating his body to great extents, using moves that he had seen before, or absorbing them when they least expect it, Buu is a very hard opponent to predict.
  • Contrasting Sequel Antagonist:
    • Unlike Frieza, an alien prodigy from birth, and Cell, who was created using the DNA of everyone and explicitly engineered to be a perfect being, Majin Buu is magical in origin as opposed to the sci-fi roots of previous Z villains (technically Buu is still an alien as he comes from space, but this is hardly relevant). This is especially true in later years were his backstory was retconned to make his true origin completely unknown, and make him more of an Eldritch Abomination.
    • Frieza was the leader of his own empire, Majin Buu was The Dragon to Bibidi and Babidi before turning on the latter.
    • Cell was patient enough to wait days for a Worthy Opponent, while Super Buu has no such patience, and can not even bother to wait a single hour.
    • Frieza and Cell were both Faux Affably Evil, while Buu is a Psychopathic Man Child who doesn't know better, or a chaotic beast that just wants destruction for the sake of destruction (Though Super Buu does become more Faux Affably Evil once he starts absorbing people).
    • Both Frieza and Cell were very stoic and serious villains, and conducted themselves with maturity, at least until stuff started to go wrong for them. By contrast all forms of Buu are much more immature and are played more for comedy, even if a lot of it is Black Comedy.
    • Lastly, compared with both Frieza and Cell, Buu gets redeemed, either by the help of someone who taught him better, or by being reborn into an innocent individual.
  • Detachment Combat: He can control any part of his body whether attached or not, and shape it as he pleases. Fat Buu used a chunk of his stomach to restrain Vegeta, Super Buu uses pieces of himself to absorb foes (and used Fat Buu's trick at one point), and Kid Buu ripped off his arm so he could turn it into a guided missile.
  • Did You Just Punch Out Cthulhu?: This guy killed all but two of the universe's highest gods, and actually absorbed South Supreme Kai and Grand Supreme Kai, the former of which was the strongest of the Kais by far.
  • The Dreaded:
    • The gods fear him and for good reason. He wipes out all life on Earth and after becoming Kid Buu he destroys several planets including Earth by abusing his regeneration and his newly acquired teleportation technique. Goku outright says that Buu can destroy a galaxy in less than an hour. The minute Buu is awakened, everyone crosses one Godzilla Threshold after another trying to stop him.
    • In Resurrection 'F' Frieza says that there were two beings that he was supposed to never mess with: Majin Buu and Beerus. Goku killing Buu is one of the many reasons why the remains of Frieza's empire stayed far away from Earth. By his own admission, he didn't feel confident in taking on someone who beat Buu until he had his Golden Super Mode, despite the massive strides he made in just his regular state.
    • In chapter 16 of the Super manga, it's revealed that even Zamasu of Universe 10 knew who Buu was (and was impressed that someone in Universe 7 defeated him), indicating that he's infamous throughout the multiverse.
  • Dumbass No More: Majin Buu is a slow-witted villain. After transforming into Super Buu, he gains an intelligence boost to some degree, but is still prone to impulsive acts and is lacking in patience and human emotion or mannerisms. However, after getting thrashed by Gohan, he manages to come up with a plan and absorb Piccolo (one of the most intelligent characters in the series) and Gotenks (a character at least his equal in power) into his body. After that, he becomes a Genius Bruiser, starts playing mind games (the Funimation dub adds emotional torment to this) on his opponents, having backup plans, and overall being a ruder version of Cell, boosted even further after absorbing Gohan himself. And then he inverts the trope, being forcibly downgraded into his Kid Buu form. His original form, which is like a very young child, is unrestrained and his most dangerous form.
  • Eldritch Location: The inside of his body is one. An entire race of intelligent worm creatures even exists there according to anime filler.
  • Enemy Without: Fat Buu and Evil Buu, the latter of which later reverted straight back to Kid Buu.
  • Evil Counterpart:
    • Evil/Kid Buu to Fat Buu after he makes his Heel–Face Turn. They are both the evil that lies within Fat Buu. They also inherit most of his power since Buu is originally an evil, chaotic being who became tame and weakened by absorbing the Kais.
    • All Buu forms to Goku. They love fighting and food above all else, learn techniques from just seeing them once, are childish, yet smarter than people give them credit for, can be playful and goofy while beating on someone and are considered to be the most powerful and dangerous beings in the universe. While Goku is a Saiyan who cares about his friends and family as well as protecting them from evil threats, Buu however(at least in the cases of Super/Kid Buu) is an entity who doesn't care about anything besides himself and destroys and kills for fun.
  • Eviler than Thou:
    • Fat Buu quickly establishes the pecking order over the arc's previous villains, including Babidi and Vegeta.
    • In Dragon Ball Z: Budokai 2, Super Buu makes his position as the greater evil undeniable by (potentially) absorbing every other Arc Villain after doing the same to Fat Buu. His what-if transformations in that game (which he can take in the campaign) include absorptions of Cell, Freeza, Vegeta, Piccolo, Tenshinhan, and Yamcha.
  • Fangs Are Evil: Super and Kid Buu have pronounced canines highlighting their much more vicious nature compared to Fat Buu.
  • Final Boss: As a whole, Majin Buu is the very last villain of the original manga and the Dragon Ball Z anime.
  • Fingerless Hands: In the manga, Buu has mitten-like hands with only a distinct thumb and index finger, though Super Buu gains proper fingers as he absorbs people and becomes more humanoid. In the anime, Super Buu has ordinary hands from the start, as does Kid Buu.
  • Fluffy the Terrible: The most powerful and most evil being in the universe is named Buu. In the Japanese text, several characters say it sounds like a fart.
  • Food-Based Superpowers: Maijin Buu has the ability to turn just about anything (including people) into junk food and subsequently chow down on it.
  • Freudian Trio: The three primary forms of Buu seen in Z — Fat, Super and Pure/"Kid" — can be equated to representing Superego, Ego and Id respectively. Fat Buu may be foolish and naive, but he manages to form his own sense of logic and morality with help from Mr. Satan and assimilates into human society (sort of). Kid Buu is pure, untamed Id with no capacity for reason. Super Buu mixes the two, as he is somewhat intelligent (especially after absorbing Piccolo) and retains a sense of compassion for Mr. Satan but otherwise selfishly indulges his destructive impulses.
  • From a Single Cell: Majin Buu is capable of reforming from single molecules. Being magically empowered instead of biological justifies this. So long as any piece of him exists in any way, shape, or form, he'll reform with varying speeds. Nothing short of complete destruction of his entire physical being will put him down. In the anime, however, Super Buu's regeneration slows down as he gets his ass kicked over and over again by Vegito, to the point where he didn't even notice that he still had a hole in his chest until Vegito pointed it out. When Kid Buu is fighting Fat Buu, Vegeta notes that Fat Buu is actually getting hurt and it's suggested he would have died of his injuries had Dende not healed him.
  • Fun Personified: Buu is a rare evil example. He is by far the goofiest villain in the entire series. He is like a reckless five-year-old with the power of a god. The fact that he looks like mutated bubblegum and has a beam that can turn people into candy and cookies really highlights this aspect of his personality. Despite all this, he is the most dangerous villain in all of the manga and the Z anime, especially his pure, original form.
  • Fusion Dance: Fat Buu is a fused being that only exists because Kid Buu absorbed two of the Supreme Kais. Super Buu is a fusion of Fat Buu and Kid Buu in a sense since Evil Buu is the evil within Majin Buu. When Fat Buu is freed from Super Buu's body he returns to his original form.
  • Genius Ditz: None of Buu's forms are especially gifted in common sense or intelligence, but no matter the incarnation he's a genius fighter able to copy moves from seeing them once, and come up with variants on the fly.
  • Glass Cannon: Played With. It's easy to notice that all of Buu's forms have bodies that are significantly less resilient that those of previous villains. Buu gets parts of his body torn off or blown up constantly during his arc, even from attacks from fighters that are noticeably weaker than him, whereas the likes of Frieza or Cell would get nothing but a scratch. On the other hand, Buu's insane Healing Factor capabilities mean that nothing but complete obliteration of his body can have any actual consequences in the fight.
  • Gone Horribly Right: Going by the flashback for Kid Buu's summoning and Buu's overall backstory, Bibidi summoned Buu to destroy everything so he could dominate over existence. Bibidi at least got that first part right, though he didn't stop to consider how he, a weak magic user, could hope to reliably control such a force. Bibidi eventually resorted to just sealing Buu and dropping him on target worlds like a bomb, a tactic which allowed the Kais to stop him. Babidi, nowhere near as smart, just tried to be a bully and earned himself a messy death.
  • Good Powers, Bad People: Thanks to absorbing the Kais, Buu gains the ability to heal people from mortal and even fatal injuries. His healing power far surpasses Dende's ability since he can restore limbs and birth defects, best seen where he regenerates Babidi who was split in half by Piccolo and when he gives sight to a boy who has been blind since birth. This trope is eventually Subverted after Fat Buu makes his Heel–Face Turn and we never see Super or Kid Buu heal anyone.
  • Hair-Trigger Temper/Mood-Swinger: To an extreme extent: he can snap from calm, inquisitive or cheerful to a towering temper or malevolent vindictiveness and back again with terrifying speed given the power he has. This makes his rampages as Fat Buu all the more disturbing, and as Super Buu it makes him nothing less than an unchecked time bomb. Keeping him calm until the heroes have someone to deal with him is a major plot point.
  • Hero Killer: He murdered or caused the deaths of nearly the entire cast, the entire human population, and blew up the Earth, the latter being something no villain had ever succeeded at prior. Not to mention numerous planets after that. He also pops the death cherry of the handful of characters who've managed to stay alive the whole series. note 
  • Horrifying the Horror: Majin Buu managed to scare the crap out of Frieza and King Cold by merely existing!
  • Humanoid Abomination: While it was originally believed Bibidi created him, it has since been stated he simply woke him up. Majin Buu has existed "since time immemorial", and nobody, nobody knows how or where he came from, and there is not the slightest thing even remotely like him anywhere in the known universe. Considering his original form is the Ax-Crazy Pure or "Kid" Buu, the universe's only saving grace until he was sealed and landed on Earth were probably his sizable hibernation periods. Just to be clear, this thing was pretty much the strongest being in existence for billions of years. Goku and the Z-Fighters only started to approach his level once they began to unlock forms and powers that warped reality, while Buu is just that strong naturally (whatever that is for him).
  • Implacable Man: Buu is relentless both physically and mentally when he's on the warpath, he's capable of absorbing his opponents should they prove too difficult for him, (which not only takes them out of the fight instantly but gives him a hell of a power boost) and while he can be hurt quite easily, it's nothing permanent. To make matters worse, only completely annihilating every single trace of his physical being to the point of nonexistence will guarantee his demise. Upon his release he successfully managed to completely steamroll several of the Z-Fighters' heaviest hitters without breaking much of a sweat. He was so powerful that the heroes could only stall him until they found someone who could actually pull off the arduous task of killing him.
  • Inexplicably Awesome: He's as old as the universe itself and no one knows where he came from or why he is so strong. Toriyama states that he became what we know as "pure" or "kid" Buu from absorbing the evils of early humanity over a prolonged time period.
  • Instant Expert: All versions of Buu can copy any technique that they see even once, a reminder that Buu is no where near as stupid as he appears to be.
  • Jabba Table Manners: Buu's a pretty messy eater no matter the form (bar Evil Buu and Kid Buu, but the former only ate once and the latter never at all). Made worse by the fact that when he turns his victims to candy, they are still alive and conscious as he noisily chews on them.
  • The Juggernaut: Buu's main strength in every form is that he has the consistency of old chewing gum with an incredible Healing Factor. Seriously hurting him is a feat unto itself, and the only way to kill him in any incarnation is by disintegration through overwhelming force.
  • Lack of Empathy: Each incarnation of Buu provides different takes on this trope. Fat Buu genuinely doesn't know any better due to his childlike demeanor and gradually learns empathy through Mr. Satan and Bee, while Kid Buu is simply too mindless to comprehend anything other than destruction. Super Buu, on the other hand, is sentient enough to know that he's inflicting harm on others and evil enough to not care and enjoy it anyway.
  • The Law of Diminishing Defensive Effort: Buu plays with this as their regenerative levels are all about the same level, and none of them arguably need to spend too much time blocking. Fat Buu, Kid Buu, Super Buu are very durable, and can heal from just about anything almost instantaneously. However, Super Buu and occasionally Fat Buu make efforts to defend themselves regardless, though Kid Buu, who abuses his physiology the most out of all the forms, never makes any real attempt to defend himself.
  • Lightning Bruiser: Especially Kid Buu, but Fat Buu and Super Buu are very fast despite their statures.
  • Literal Split Personality: What makes Majin Buu unique compared to the other villains in the series is that he has three different personalities with their own motives, morality, and wants. Fat Buu is an innocent child-like being who has been manipulated into doing bad things because he didn't know any better. The moment he learns that his actions are evil, he swears off killing. When Fat Buu expels all his evil, that evil becomes Evil Buu and when he eats Fat Buu, he becomes the more powerful Super Buu, who is a cruel and cunning Blood Knight who only wants to fight stronger people and be the strongest in the universe by any means necessary. He is also the smartest of all the Buu forms, although his Pride in being the strongest makes him somewhat easy to manipulate, which Vegito takes full advantage of. When Fat Buu is separated from Super Buu's body, he reverts back to his original pure evil form, Kid Buu. This version of Buu is more of a force of nature than a personality, since he lives only to kill and destroy, and doesn't care about getting a good fight or being the strongest in the universe. This makes Kid Buu the most dangerous form since he has no character flaws to manipulate, and can't be reasoned or bargained with.
  • Logical Weakness: As powerful as Majin Buu's Healing Factor is, it's not flawless. If constantly pressured with powerful attacks, his regeneration weakens since it takes more power and focus to heal from them, especially if the attacks are constantly occurring. This is seen in Super Buu's fight with Vegito, and Goku's fight with Kid Buu; Vegito beats Super Buu so brutally that his regeneration actually starts failing and causes him to forget to regrow some parts of his body, while Kid Buu endured so many powerful attacks from Goku that he ended up regenerating his head between his legs. Essentially, to defeat Buu, one has to pressure him to the point he can't regenerate fast enough.
  • Made of Plasticine: Notable in that while everyone else is pretty much Made of Iron, even normal handgun rounds can punch holes in him. Of course, he makes up for this with ridiculous regeneration powers. This gave the animators a good chance to go wild with the kind of injuries Buu would suffer, ranging from being blasted to bits to get his head smooshed into his neck, and so on.
  • Magic A Is Magic A: Averted. Majin Buu's magic is nothing like the series had seen before. He can transmogrify living beings into anything he wants (usually candy), regenerate from any wound instantly, etc. What's worse is that Buu can't understand himself. Vegeta justifiably raises concerns that Fat Buu could easily spit out another evil Buu at any time and no one would be any the wiser.
  • Mars Wants Chocolate: He's an Eldritch Abomination that is obsessed with candy in general and chocolate in particular, to the point that he prefers to kill enemies by turning them into candy and eating them. Though Fat Buu notes chocolate made by people is better than that made from people.
  • Morality Chain: Both Mr. Satan/Hercule and Bee, before he transforms to Super and Kid Buu.
  • Mysterious Past: After his origins were retconed, nothing is really known about Buu outside of being as old as the universe and summoned to act as Bibidi's weapon for universal conquest.
  • Named by the Adaptation: In the anime and manga, all forms of Buu are simply referred to as Majin Buu; Kid Buu, Evil Buu, and Super Buu got their names from the video games.
  • Nigh-Invulnerability: He has to be destroyed to the very last molecule, since he can regenerate from even mist particles of his being. However, he doesn't have Super-Toughness. Unlike previous examples like Frieza or Cell, physical blows from even a weaker opponent will noticeably deform his body upon impact and even ki blasts will punch through him easily, it's just that he can reset it just as quickly.
  • No Biological Sex: While most of Buu's forms look and sound male, as a primordial amorphous blob with extensive shapeshifting abilities, Buu can take any form he desires with little issue.
  • Not-So-Harmless Villain: When first introduced, everyone not familiar with Buu perceived him as a joke, seeing him as a large, pudgy, pink infant. Babidi and Dabura thought that Buu's resurrection was not a success, Gohan had his doubts and Vegeta thought that Buu's power was only a threat when the universe was much weaker. Only the Supreme Kai knew better. After Dabura insulted him, Buu quickly showed everyone why he was so feared.
  • Obsessed with Food: Something all the Buu forms have in common. He is one of the few characters that is more obsessed with food than Goku. Unique to Buu, he love sweets and can easily eat two cities' worth. He more often than not uses his reality warping ability to turn people or objects into food.
  • One-Winged Angel: Has the most transformations of any villain in Dragon Ball, and one of the most unusual variations since the power zigs-zags all over the place with the transformations.
  • Our Genies Are Different: Very different. In a 2007 interview, Toriyama stated that he came up with Buu's design because he saw Arabian Nights as a kid, and "had this set image of what a majin, or genie, should look like", confirming that he thinks of Buu as a kind of genie. The Viz English translation of the manga directly calls him a "genie" or "djinn" depending on the character, and his Japanese title of "majin" (literally "magic person" or "demonic person") is often used as a synonym for djinn/genie (the blue guy from Disney's Aladdin was called a majin in the Japanese dub, for instance). Buu shares many attributes with the djinns of Arabian folklore, including sporting stylistically Arabic clothing, being sealed inside an object for a long time, materializing from smoke when released, being extremely long-lived, having magical powers such as shapeshifting and transmutation (typical djinn abilities), being summoned by a sorcerer to serve him, being bound to the sorcerer by an incantation, being summoned to Earth by draining peoples' life force (similar to an Ifrit), having an evil corrupted grey form (similar to a ghoul, which in some tales is a corrupted djinn), and being naturally stronger and faster than other beings, yet nonetheless still killable by physical means. Also, his good version in Dragon Ball Online is blue, invoking a marid.
  • Outside-Genre Foe: Buu, for being as close to an Eldritch Abomination that Dragon Ball continuity would allow. This bizarre pink genie creature has terrorized the universe, cowed the gods themselves, can transform you into conscious food while eating you alive, or absorb you by using its own malleable flesh to break off and consume you as it reintegrates with him and transforms into a new form, taking some of the traits of the victims (this happened to God), and, sufficiently enraged, he can tear through dimensional barriers, potentially causing universal collapse should he manage to hit enough at once. His pure, untainted form, Kid Buu, is even worse. Unlike all the other villains, he can't be reasoned with, he has no pride to take advantage of, and no desire for anything except killing everything. In order to beat him, the protagonists literally have to go to the one planet that he can't blow up in one shot. Even then, he's close to being an immortal given his endless energy and regeneration. He can even teleport into the afterlife, killing you for good after he kills you the first time. Buu's origins were also retconed to make him more out of context. It's originally believed that Bibidi created Buu using an advanced form of magic. We later learn that Buu is as old as the universe itself and no one knows where he came from or how he was born, making him an outside context villain for the entire universe.
  • Perpetual-Motion Monster: In all his incarnations, Buu is naturally very powerful, is a fighting prodigy, and has shapeshifting and absorbing his opponents under his belt. But far and away the most dangerous thing about him is that he has bottomless energy and stamina, including the ability to immediately heal up from anything short of disintegration.
  • Physical God: He’s so powerful that he killed off several real gods prior to the start of the series. He has the most powerful regeneration in the series (capable of returning from a single atom), has powerful telekinesis, Voluntary Shapeshifting, ability to turn anyone into anything else (usually some form of confectionery which he eats), doesn't age (he's older than the universe itself), Power Copying, limitless stamina, absorption of others to acquire their strength and abilities, can annihilate a planet's population without destroying the actual planet, break dimensions just by screaming, can casually blow up stars in his weakest state (he did this millions of times), and teleportation which he copied from an actual god. All of this on top of the standard super strength/super speed/flight/etc. power set that everybody else has, only cranked to insane degrees- in his weakest form he one-shotted Super Saiyan 2 Gohan and the aforementioned Dabura, and curb-stomped Super Saiyan 2 Majin Vegeta. At his strongest? He can cause the entire universe to collapse on itself just by getting angry and screaming really loudly. Save for Beerus, Buu is more of a god than the actual gods.
  • Ping Pong Naïveté: He lacks a lot of common sense and general knowledge, but he's very intelligent when it comes to fighting, being able to learn moves after seeing them once. Also, even though he did not know what an hour was, after Piccolo showed him a sand timer, he was able to count the grains of sand and calculate how long an hour was in a matter of seconds.
  • Power Copying: He can both imitate attacks he's seen only once and gain abilities from absorbing people.
  • Power Limiter: Zigzag all over the place. After Buu absorbs the Grand Supreme Kai, he transforms into the more docile Fat Buu. Supreme Kai even bemuses that his master did this on purpose so he could give Buu a conscience. After Fat Buu gets eaten by Evil Buu, he becomes the much more powerful Super Buu, but he is also restrained by emotions such as arrogance, pride, and his friendship with Mr. Satan. Once Fat Buu is disconnected from Super Buu, he returns to his pure form who can use his power to its fullest, since he has no emotional restraint. However, even while disconnected, Fat Buu still manages to influence Kid Buu, keeping him from killing Mr. Satan until he spits him out.
    • The dub version of the Buu arc is a little messy in places. It's generally accepted that Fat Buu is an order of magnitude stronger than Kid Buu because he absorbed powerful opponents (this is before taking into account that Fat Buu lost power when he expelled Evil Buu). However, Kid Buu has no restraint when it comes to fighting and won't stop to banter. Fat Buu is too innocent to fight to the peak of his abilities and gets clobbered by Kid Buu as a result. Buu was originally an evil creature who absorbed evil energy to become stronger. Having a conscience prevents him from tapping into that power, but does not eliminate it. A better translation of the Supreme Kai's statement is that absorbing the other Supreme Kais "tamed" Buu instead of making him weaker. Also, despite his incredible stamina, each version of Buu will eventually start wearing out and take longer each time they try to heal themselves. However, if any piece of him is left behind after a fight, it's only a matter of time for Buu to rest enough to regenerate since he can't die of exhaustion, only obliteration.
  • Psycho Pink: Majin Buu is an Omnicidal Maniac who, in addition to being completely pink, looks pretty silly, at least as Fat Buu. This trope becomes more pronounced with Super Buu, who's the result of Fat Buu being eaten by Evil Buu, who doesn't fit this trope, and Kid Buu, the original and most dangerous form of Majin Buu.
  • Psychopathic Manchild: Fat Buu is the obliviously-evil type, Super Buu acts a bit more refined but tends to throw hissy fits when outmatched (even after absorbing Piccolo and Gohan), and Kid Buu is just completely off his rocker.
  • Pyrrhic Victory: A tragic example; in his story mode in "Budokai Tenkaichi 3" he defeats the heroes and proceeds to destroy everyone, only to discover what it is like to be all alone... forever.
  • Reality Warper: The strangest example in Dragon Ball. While other reality warpers have more unique techniques, Buu's are downright destructive and powerful. He can literally destroy all of reality and everything in it... by screaming. No one, not even himself knows how or why this works. When Super Buu gets mad enough while losing to Vegito, he has a freak out that Vegito realizes can destroy the entire universe. Vegito, being far stronger than Super Buu barely manages to beat the technique and smacks Buu so hard that he calms down and starts thinking logically again.
  • Red Eyes, Take Warning:
    • A Trope Codifier for anime villains, though not at first, as both given later revelations about his origin or lack thereof, it's likely a nod to Sun Wukong gaining red eyes. Evil Buu and Super Buu at first had white pupils instead of the iconic red. However, after Gotenks managed to hit him, his eyes turned red, possibly his version of Turns Red as finally being aware of a powerful fighter.
    • It's really more to do with the anime adjusting itself to the manga, as the color of Buu's pupils was only revealed on a color chapter cover.
  • Real Men Wear Pink: More like "Real Men Are Pink", but still; a Trope Codifier for villains, though the manifested evil form is grey.
  • Remember When You Blew Up a Sun?:
    • Buu killing all the Supreme Kais except one is referenced several times, and is even a plot point to explain how Kid Buu became Fat Buu.
    • For the heroes, Buu firmly becomes The Dreaded after he kills Vegeta and (supposedly) Gohan. Chi-Chi went as far as to slap Buu because he murdered her son and Goku takes Buu very seriously when they first meet, thinking that despite Buu's silly personality, he did kill Vegeta.
    • He also ends up being the "sun" for someone else. Goku's defeat of Majin Buu is known across the universe to the extent that it is one of the many reasons why Frieza's empire stood away from him and the Earth, and even Frieza is greatly impressed when he hears that Goku killed Buu, as it turns out he knew about Buu and was told to never mess with him.
  • Retcon: Buu's origin. In the original release, he was a monster created by the wizard Bibidi. Years later, this was retcon'd into Buu always existing with no one knowing where he comes from. Bibidi only learns how to summon him from hibernation and imprison him if necessary.
  • Rubber Man: A psychotic, superpowered flying wad of bubblegum.
  • Shapeshifter Default Form: He can stretch and manipulate his body in increasingly odd ways, yet after he's done doing so for whatever purpose, he'll always revert to that form's default visage. Usually a combination of Kid Buu (a pink bubblegum-esque demon with red eyes, a head tentacle, and holes in his skin) and whoever he has absorbed. He also always wears the same pants.
  • Shape Shifter Guilt Trip: Whenever Buu absorbs someone, he takes on their physical traits and mannerisms, which makes for an unnerving fight if the person fighting is a close friend or loved one. It's heavily implied that beyond his abilities surpassing the other Supreme Kais, especially after his first absorption, is that his appearance and mannerisms are a constant traumatic reminder to Supreme Kai that his comrade, Grand Supreme Kai, was absorbed by Buu and the monster commits atrocities with those traits as a further reminder of that failure to prevent that. Fat Buu himself, doesn't capitalize on this aspect of himself due to being concerned about destroying on his master's orders and being naive outside of it.
  • Shout-Out Theme Naming: Between him and his two masters, put them together, and what have you got?note 
  • Single Specimen Species: Buu is a very odd humanoid shapeshifting genie made of pink gum-like material, and there is absolutely nothing else like him in the multiverse. Apparently other Majins/djinns exist, since Gohan and Trunks both had preconceptions about what Buu would like ("I thought he'd be bigger..."), but they're nothing like him. Expanded universe material like Xenoverse and Online have Fat Buu giving birth to an entire race of Majins, but he remains this in the main series itself.
  • Sinister Sweet Tooth: Though he goes through various transformations, a common trait of Majin Buu is his taste for candies: most memorably, Fat Buu converts his opponents into chocolates and candies so he can eat them. In the anime, even the near feral Kid Buu briefly takes a pause to much on some sweets created by one of Fat Buu's deflected chocolate beams.
  • Slasher Smile: In all forms, even Fat Buu occasionally. Special mention goes to Super Buu.
  • Smarter Than You Look: All the Buus display this at one point or another, and it leads to the biggest blunders anybody opposing them makes in assuming they're entirely stupid. Fat Buu is always aware that Babidi needs him, and plays along until he gets tired of it and easily outwits his "master". Super Buu is probably the best example, as he deliberately acted like a simple-minded thug to get others to get overconfident with him, even managing to fake his fight with Gotenks as serious when in reality he was waiting for Gohan. Even Kid Buu gets in on this, quickly realizing that Goku won't throw the Spirit Bomb since Vegeta is in harm's way, and parks himself right on top of the felled prince to render Goku unable to move as he'd drop the Spirit Bomb, but also unable to throw it, leaving him at Buu's lack of mercy.
  • Spell My Name With An S:
    • Bandai and the subtitled version of the anime uses "Majin Boo", while Funimation uses "Buu" for their dub. Viz used "Boo", and also translated "Majin" as "Djinn."
    • 魔 ("ma") can mean sorcery or demon (it's the same character used in Piccolo Daimaou). 人 ("jin") means person, but it also used to indicate a person's ethnicity ("Amerika-jin" for American). Majin can be a Japanese word for genie (or djinn). The only problem with replacing "Majin" with "djinn" is it removes the alternate meaning of "demon."
  • The Starscream: In his original form, Bibidi could barely control him (it's implied he'd just seal him, drop him off wherever he wanted the damage done, then repeat as necessary). Even Fat Buu wasn't terribly loyal, and eventually killed Babidi when he figured out he didn't have to listen to him.
  • Story-Breaker Power: Buu's transformation ray can turn anyone (including itself) into food or an object of Buu's desire, and is unblockable. The only saving grace is that can be dodged if a person is fast enough or expects it. However, one slip and you're dessert. This is on top of being able to reform from a single molecule and his absorption technique that allows him to take in any fighter and gain their knowledge, techniques, and power, though the latter can backfire and make him weaker if he absorbs the wrong type of person. Buu eventually became so broken that it takes an equally broken character to surpass him.
  • Super-Breath: He used this to destroy a city. He obtained it after absorbing the Grand Supreme Kai; when he used it, it doubled as a Razor Wind.
  • Superpower Lottery: At his weakest he was stronger than Cell at his absolute best (Cell was a near match for a Super Saiyan 2 at his best, Buu laughably outclassed them and could reasonably keep pace with Super Saiyan 3s). Like Cell, Buu could regenerate, and took it up a notch (his vaporized molecules were sufficient to resurrect him in seconds). He also had the ability to absorb other beings, gaining their abilities, strength, and skills... which he abused the hell out of. On top of that, he was also magical - pretty much a low-level Reality Warper, with the ability to turn just about anyone into just about anything (usually food). Once he'd gotten the ball rolling, the only being in the entire universe able to stand against him was Vegito, a fusion of the two strongest warriors on the planet (a fusion done via godly magic to boot, which was the only reason he wasn't felled when Buu turned him into candy).
  • Super-Toughness: While Buu in all his forms is tough, his body noticeably deforms when struck even by weaker opponents and even ki blasts from weaker foes can tear right through him whereas most fighters would just plain shrug them off with no effect. The catch is that his his body will quickly reset or will regenerate with ease. During Kid Buu's battle with Goku, both of them blast each other with a Kamehameha that results in Kid Buu being torn to pieces while Goku just adds to his collection of bruises.
  • Tangled Family Tree: Let's see, Kid Buu absorbs South Supreme Kai to become Buff Buu, and then absorbs Grand Supreme Kai to become Fat Buu. Then Fat Buu releases the evilness from himself in rage which manifests itself into the Evil Buu, who subsequently absorbs Fat Buu and becomes Super Buu. Super Buu absorbs Gotenks, Piccolo, and Gohan only to have them ripped from inside of him by Vegito (who also removes Fat Buu). After all of these are removed, Super Buu becomes Kid Buu again, who is then destroyed and reincarnated into Uub. This can confuse a lot of people since it would seem like removing Fat Buu from Super Buu should turn him back into Evil Buu, but it doesn't. Also, while Fat Buu releasing his Evil side made him weaker and him being rejected by Kid Buu made Kid Buu weaker, Fat Buu could theorhetically be changed back into Kid Buu again if someone was to get inside of him and remove the Supreme Kais that he absorbed. Despite all of this, each Buu also seems to have limitless potential if Super is anything to go by and each Buu can become the strongest version of himself regardless if they absorb their opponents or not. All of this doesn't even take into account the games many different timelines and questionable canonicity where you get Buu's descendents born from the union of him and a female version of himself that he created in Dragon Ball Online, his descendents(?) that somehow formed in Xenoverse, or characters like his clones or Majin 21 in Dragon Ball Heroes
  • Time Abyss:
    • Buu has lived for millions of years. In fact, Toriyama has stated that Buu has existed since the beginning of time, awakening, rampaging, and going to sleep in long cycles. Bibidi didn't create him, he just woke him up.
    • Which makes Buu remarkably similar to a classic RPG villain that Toriyama did the artwork on. The misinformation about who created Buu as well as being a timeless entity that rains destruction before going into a state of habituation mirrors the story of Lavos from Chrono Trigger.
  • Turned Against Their Masters: Majin Buu betrays Babidi, prevents him from saying the incantation to seal him away before murdering the sorcerer.
  • Took a Level in Jerkass:
    • Every time he transforms. He goes from goofy and misguided Fat Buu, to the cunning and cruel Super Buu, to the completely bat shit crazy Kid Buu.
    • After the retcon on his origins, Buu happens to be a creature that, while bent on having ocassional rampages of destruction all over the universe, became worse after coming across the evils of early mortals.
  • Transformation Ray: He can fire one from his head-tentacle. He mainly uses it to turn people into candy, making it a One-Hit Kill if it hits. The drawbacks? In addition to only affecting organic matter, the beam itself is so slow and weak that Evil Buu was able to literally blow it back at Fat Buu and turn him into chocolate; later, Vegito is even able to keep his sapience and power when hit by it and turned into a jaw breaker. The Daizenshuu explains that this was because of the Kai magic of his earrings.
  • Unblockable Attack: The above mentioned transformation ray cannot be blocked by any means. While it can be thrown back at Buu himself and be dodged since it's so slow, getting hit by it is an instant kill as Buu can use it to transform you into whatever he wants. More often than not candy to be eaten.
  • Unskilled, but Strong: Their attack animations in the video games are just them flailing their limbs around. In the show itself it's more a mixed bag: Buu has a fighting style that might best be described as "chaotic" and often relies on brute strength, but he's certainly capable of great skill. He's particularly good at coming up with inventive ways to use his rubbery, stretchy body in combat, even the fat one.
  • Unstoppable Rage: His Ax-Crazy tendencies and (In any form aside from Fat Buu) Hair-Trigger Temper make him easy to anger and is a nightmare when he does go off.
  • Victory by Endurance: A stronger opponent is capable of beating on Buu and causing him injury, temporarily weakening him. But unless he is completely disintegrated, he will be back and at full strength shortly, and eventually he will wear you down. Note that by complete disintegration, we mean "completely wiped from existence in a way that violates the law of conservation of matter"- reducing him to smoke particles wasn't enough to do this. Kid Buu and Super Buu manage to win against their respective Super Saiyan 3 opponents simply by outlasting their opponent's stamina. Fat Buu may very well have been able to do the same had his Super Saiyan 3 fight actually been drawn to its conclusion (Goku claims he could've finished it before that became an issue, but his claim was never validated and circumstantial evidence such as his state at the end of the fight relative to Buu's and his later underestimation of Super Saiyan 3's energy drain could suggest otherwise).

    Fat Buu 

Fat Buu (魔人ブウ 無邪気, Majin Bū Mujaki, "Innocent Majin Boo" / 魔人ブウ 善, Majin Bū Zen, "Good Majin Boo") / Mister Buu / Mr. Boo (ミスター・ブウ, Misutā Bū)

"So, do you want to be candy, cookie, or pudding when Buu eats you?"

The form in which Buu appears when Babidi releases him, much to everyone's surprise. "Fat Buu" is an obese, gluttonous, genie-like creature who looks like he's made out of bubblegum. In this form, all Buu cares about is eating sweets, fighting strong opponents, and blowing up cities and planets for fun, unaware of the pain and anguish he causes. This changes when Mr. Satan tries (and inevitably fails) to kill him and instead becomes Buu's friend, something which gradually puts Buu on the path of learning to care for all life. When Satan (and Bee, a stray dog Buu adopts) is shot by a human criminal, Buu, overcome with rage and pain, literally expels his evil side from himself, fights him before getting overpowered and absorbd by Evil Buu, thus turning into Super Buu.

Later, when Goku and Vegeta are inside Super Buu looking for their absorbed friends, they also find Fat Buu, whom they free, causing Super Buu to transform into Kid Buu. Fat Buu, now firmly on the side of good, helps hold off Kid Buu while Goku charges his Spirit Bomb. When Kid Buu is finally defeated, the heroes responsible wish on the Dragon Balls for the general populace's memory of Babidi and Buu to be erased so that Fat Buu, now called "Mister Buu" as Mr. Satan's sidekick and a celebrity in his own right, can stick around.

In the timeline of Dragon Ball GT, Fat Buu merges with Uub to become Majuub, effectively ceasing to exist. In the Dragon Ball Online timeline, however, he creates a wife called Miss Buu, and together they beget a whole new race of friendly Majins who populate the Earth.

  • Acrofatic: In spite of his large and round body, he's surprisingly fast and agile.
    • His introductory scene shows this well. He gives SS2 Gohan and the Supreme Kai a huge head start to run away, before finally starting to chase them. He not only easily catches them, but he also proceeds to Flash Step in front of them without them realizing he'd moved at all.
    • Despite being an obese pink blob with thin limbs, he manages to fight on par with Goku's Super Saiyan 3 for a bit, and is Vegeta's superior in combat.
    • In Dragon Ball Super episode 85; after intense training has now become lean, stronger, and faster in how he battles.
  • Adam and Eve Plot: Between the events of Dragon Ball Z and Dragon Ball Online, he created a wife for himself, and fathered an entire race of Majins.
  • Affably Evil: Fat Buu’s jolly, childlike nature and willingness to treat even mass murder like it’s all just a game is completely genuine. When confronted by people who won’t run from him, he’s genuinely curious; and when confronted by Mr. Satan? Opts instead to make him his friend. When Satan tells him that killing is wrong? Buu decides he won’t do it anymore. It’s justified in that, inspite of Buu’s actions being evil, he genuinely doesn’t know any better and was told by Bibidi that murder was all a game. He’s very much like an infant or a child and needs to be taught right from wrong.
  • Ambiguous Innocence: This is what makes this version of Buu so dangerous. He thinks like a child; all he did is one big game, including murdering everyone on a planet, or turning them into food and eating them. Goku in the dub describes him as a naughty child. As soon as Mr. Satan explains to him that killing and destruction are wrong, he pulls the plug immediately, claiming that he will never kill again. It comes up again after he's gotten lean in the Universe Survival Saga, excitement prompting Buu to say he'll exterminate all his opponents - when told he can't kill them, he's curious when asking if he really can't, but easily seems to accept it and uses ring-out tactics against Goku.
  • Ambiguous Situation: At the end of Buu saga Goku tells Vegeta he could have most likely defeated Fat Buu in his Super Saiyan 3 form, but whether this was true causes some serious doubt for a few reasons. Mainly, his first bout against Buu is largely Buu simply playing around and taking the fight much less seriously than Goku, and yet the two seemed to be about even. Secondly, the stamina drain of Super Saiyan 3 affects him greatly in a fight much more than he anticipated and seeing how a full powered fight between them both would have prolonged things— it causes major doubt on whether or not Goku would win, though Goku does later note it takes more energy to use Super Saiyan 3 when he's alive rather than dead, but even after his fight with Buu when he is dead, when talking with Piccolo Goku claims he only has an hour left, but it turned out to be 30 minutes, so Goku still slightly underestimated just how much time Super Saiyan 3 drains in the living world. To make Goku's claim even more doubtful, when fighting Kid Buu, he is surprised and frustrated just how resilient Buu is and notes that his ki never goes down, a problem he would also have to deal with against Fat Buu.
  • Anti-Villain: Type III bordering on Type IV. He is easily the most sympathetic Arc Villain in the series, and aside from Vegeta, the only one in Dragon Ball Z to turn good. He kills and destroys only because it's all he was ever taught to do and he doesn't really comprehend at first that it's wrong. When Hercule explains to him that it is, he has no problems stopping.
  • Asleep for Days: In Super, he has a habit of falling asleep for months due to his natural hibernations. This is a problem as he keeps falling asleep when the heroes need him, such as when Frieza invaded the Earth or during both the U6 Tournament and the Tournament of Power.
  • Ax-Crazy: Especially in Vegeta's fight. Mostly because Vegeta got him mad by calling him names.
  • Badass Adorable: Especially after his Heel–Face Turn.
  • Badass Cape: Due to inheriting the old Grand Supreme Kai's outfit. It isn't actually a cape though, it's part of his body. Yet he can still take it off. Weird.
  • Balloon Belly: Due to inheriting the old Grand Supreme Kai's figure and being a stretchy being.
  • Berserk Button: Calling him names or harming Mr. Satan and/or Bee will be the last thing you'll ever do.
  • Beware the Silly Ones:
    • To say that his debut probably left many a viewer confused would be easy; after all, he's a babyish blob monster. Then he oneshots Gohan, who fought on par with Dabura, who was as strong as Cell.
    • Universe 9 finds this out the hard way: at first both Basil and Roh think he's nothing but a buffoon...then Buu gets mad. The end result is Basil getting completely manhandled. Even with a Power-Up Food from Roh, Basil ultimately loses without leaving so much as a scratch on Buu.
  • Big Bad: For the Buu arc, before he turned good. Specifically, he's the main villain for most of volume 39 and all of volume 40.
  • Big Eater: Fat Buu loves to eat, and devours massive amounts of sweets, candy, and pastry at the slightest opportunity. In fact, he's such a glutton that he will devour entire city populations by changing all of the people into food.
  • Breaking the Fourth Wall: In one episode of Z he builds a house, then proceeds to tell the audience the various parts of it, as well as say, while he's brushing his teeth, that you should always remember to brush. It's so bizarre and out of place it arguably counts as a BLAM.
  • Brilliant, but Lazy: Not to the point of Frieza, but Buu is shown to be capable of near-instantly copying certain moves and was second only to Beerus and Whis in power in Universe 7 initially. However, he never really trains or tries to improve. That is until the Universe Survival Arc where he actually does train. For two hours. The result is him gaining a Super Buu-like form and increasing his speed and strength immensely. Two hours. Judging by the Moro Arc, this power boost seems to have stuck even after reverting back to his fat form.
  • Brought Down to Badass: He was considerably weakened from his full potential (that being Super Buu) when he expelled Evil Buu from his body, but he still has quite a bit of power left to him. He was able to put up a decent fight against Kid Buu at the end of Z, in which both fighters repeatedly inflict damage that would kill the other if not for their respective regenerative powers. In Super, he's easily able to beat back Basil, one of Universe 9's top warriors, and Goku considers him one of his top picks for both the Universe 6 tournament and the Tournament of Power.
  • Character Development: He gets quite a bit, surprisingly. Starts off as a violent psychopathic child, but learns compassion and respect for life from interacting with Hercule and his dog Bee. By the end, he's still childish but is kind and gentle.
  • Chick Magnet: By the series finale. Not that he notices much.
  • Combat Compliment: He praises Super Saiyan 3 Goku during their brief fight since he is the first foe he fought that he didn't steamroll.
  • Crouching Moron, Hidden Badass: Out of all the Buu forms, Fat Buu appears the most harmless with his childish and playful demeanor. Dabura actually calls him an utter idiot and Gohan thinks Buu can be tamed since he's like a kid. While this (Gohan's) assumption ultimately proves to be correct, it isn't realized until long after Buu reveals how dangerous he actually is by easily defeating Dabura, Gohan, the Supreme Kai, and Vegeta without taking any real damage.
  • Conservation of Ninjutsu: Zig-Zagged. Gohan, Dabura, and Shin all fall in seconds before him, but then Goku says that if he and Vegeta (both being slightly stronger than Super Saiyan 2 Gohan at the Cell Games) take some senzus and team up, they'll definitely be able to beat him. Then he powers up more after Vegeta insults him. After this (and Vegeta's death), it's explicitly stated that no number of Super Saiyan 2s would have a chance against him.
    Goku: “Damn it! If only Vegeta and Gohan were still alive, I might have a chance...”note 
    Piccolo: “No. It wouldn't make the slightest difference how many of you were here.”
    • It's also lampshaded during Vegeta's fight with Buu. Goten and Trunks rush in (each was shown earlier in the arc to be decently close to the adult Super Saiyans during spars) and offer to give him a senzu and all go at Buu together. Vegeta simply says that it won't make any difference.
  • Curb-Stomp Battle: His "fights" with Dabura, the Supreme Kai, Gohan, Goten, Trunks, and Vegeta.
    • Vegeta probably got the worst of it; after selling his soul in order to reach his current power, Buu still reduces him to a bloody and broken mess (complete with a broken arm) in just one attack.
    • His battle with Gotenks results in Fat Buu beating him senseless with ease.
    • He becomes a victim of this in his fight with Evil Buu, who dismantles him in just a few panels in the manga. The anime makes it an extended No-Holds-Barred Beatdown.
    • His fight with Kid Buu is more of a Curb Stomp Cushion. He loses, but he puts up a decent fight at first (the Buus repeatedly hit each other with attacks that would kill the other if they couldn't regenerate), which pisses off Kid Buu to no end, as he was expecting a complete weakling he could toy with like Vegeta.
  • Creepy High-Pitched Voice: In the original dub, when he powers up to fight Vegeta, his Helium Speech goes even higher than even his usual squeakiness allowed. It managed to be very jarring and disturbing.
  • Depending on the Writer: Buu's characterization in the post-Z series varies drastically. In GT, he's portrayed as surprisingly Older and Wiser since Z, as he's much more levelheaded and verbose than before (in the Japanese dub, at least). He recognizes his connection with Uub, which leads to him effectively sacrificing himself in order to fuse with Uub and give him a mighty power boost, much like Kami to Piccolo. Although Uub still gets beaten by Baby, Majuub later attacking Baby from the inside proves instrumental in saving the day. In Super, Buu is infamously treated as The Load, being totally unreliable in contributing anything to the Dragon Team's efforts in most arcs (in fact, he sometimes makes matters worse, like with Beerus's "pudding incident") and still generally acting like a big toddler.
  • Deus Exit Machina: No less than four times in a row is Fat Buu taken out of the story to raise the stakes in Super, as he's either simply not available, or has fallen asleep randomly.
  • Disc-One Final Boss: Fat Buu ends up like this to Super/Kid Buu, since they are both more powerful than he is and far eviler.
  • The Dog Bites Back: Goku chides Buu for taking orders from a weakling like Babidi before abandoning their fight. Taking that to heart, he decides he has had enough of being barked around by his "master". Tricking Babidi into getting too close for his own good, he chokes him to keep him silent and punches his head off, eliminating any risk of Babidi trying to seal him back in.
  • Dragon-in-Chief: Starts off as one after killing Dabura. Nobody gives a shit about Babidi after he shows up. Unfortunately for Babidi, Buu joins that list. Fat Buu lampshades this earlier when Babidi threatens to reseal him before fighting Goku, Buu points out that Babidi would be defenseless if he tried. Lucky for Babidi, at that moment, Buu was more interested in fighting Goku.
  • Earn Your Happy Ending: Spent countless eons being used as a weapon of devastation by Bibidi and then Babidi, with much of his life sealed away. Then, when he makes a friend for the first time in his life, he promises to renounce his destructive ways but is overtaken by his evil half who continues his spree of devastation with Good Buu trapped helplessly in his psyche. He's eventually freed and is subsequently nearly beaten to death in a battle against his original self but ultimately survives and is finally given a second chance to enjoy life in peace with his new friends, one of whom is incidentally one of the richest and most famous person on Earth and can easily provide the funds needed to feed Good Buu's massive appetite.
  • Establishing Character Moment: When he is freed from his ball, Buu spends several minutes dancing around like a little kid, much to the confusion of Babidi, Dabura, and Gohan. Gohan thinks Buu is innocent and perhaps can be reasoned with (this is later proven to be true, but Buu is currently at odds with his dark side). Dabura thinks he's a stupid fool who is unaware of anything. Then Buu punches Dabura in the eyes before punching him into a cliffside.
  • Evil-Detecting Dog: Has this demeanor towards Evil Buu when the latter first appears.
  • Eyes Always Shut: Except when angry or about to kill.
  • Fat Bastard: At first, before he Took a Level in Kindness thanks to Mister Satan.
  • Fat Idiot: Double subverted, he is not bright, but he was actually dumber before the absorption that left him with his pudgy form. Furthermore, Fat Buu is the only Buu willing to abandon evil, which means he's the only Buu who gets to survive.
  • Flanderization: Buu gains a habit of falling asleep at really inopportune moments. While this was somewhat indicated by Kid Buu's sudden nap, this is used in a manner that feels like an excuse to not have him to participate in any tournaments or any clashes where the opponents would have to deal with his wild array of abilities.
  • Game Face: When he got serious prior to the Tournament of Power, he got in shape, losing a few hundred pounds in a matter of hours, and ended up looking more like Super Buu more than anything. Unfortunately, the effort left him hungry and tired, so he immediately gained it all back after binge eating, which had the side effect of him taking a "nap" which would last about two months. In the interim, Goku would have to search for a replacement, necessitating the recruitment of Frieza.
  • Genius Bruiser: A Downplayed example since this version of Buu is the most naive. At the same time, he tricks Vegeta into getting wrapped up in his own blubber and he realizes quickly that Babidi needs him to keep him from being killed by Z-Fighters. He also finds a way to kill Babidi before he can seal him again by tricking him into coming in close and clamping his mouth shut to prevent him from saying the sealing incantation. Finally, he learns the Kamehameha and one of Vegeta's techniques just by seeing it once. In Xenoverse 2, Akkah also notes that Buu reads tons of books and processes information pretty quickly when he actually wants to, saying he's "surprisingly, quite the studier."
  • Gentle Giant: Post-Character Development. He's huge, immortal, and powerful enough to blow away solar systems, but kind and gentle.
  • Get Out!: Screams at Mr. Satan to leave when he starts losing control of his anger and inner evil: unable to keep it suppressed, there's little Buu can do but order Satan to get to safety.
  • God-Eating: One of his first acts is turning the Demon King Dabura into a cookie and eating him after beating him up to establish he's a threat. He also considers eating the Supreme Kai but never gets around to it.
  • Healing Hands: He can heal grievous wounds, or even physical disabilities like blindness.
  • Heavy Sleeper: In Super, Buu has swapped his hibernation to falling into periods of deep sleep. However these periods typically last for months, during which he is almost impossible to awaken. As luck would have it, he always falls asleep when others need him, such as when Frieza gets revived and attacks the Earth, during the test for the Universe 6 Tournament, and again in the Universal Survival Saga where after he has a sparring match with Goku.
  • Heel–Face Turn: Thanks to Hercule of all people. All of Hercule's laughable attempts to kill Buu only makes him like Hercule and they eventually form a friendship. When Hercule ask Buu why he kills and destroys, Buu reveals that is what he's been taught his entire life. When Hercule tells Buu that killing is wrong, Buu vows never to kill again. This would have been the end of the saga…if Van Zant never happened.
  • Helium Speech: In the Funimation dub. Less present in the Japanese version where his normal speaking voice is pitched fairly low and becomes higher-pitched when he's angry or excited.
  • Helpless Good Side: After being absorbed by Evil Buu, he remains trapped inside the bodies of Super Buu and Kid Buu, unable to do anything other than keep them from attacking Mr. Satan, Bee, and Videl initially (and even then, Super Buu still kills Videl later on and, in the anime, he's slowly preparing to attack Bee and Hercule after absorbing Gotenks and Piccolo when the former duo tries to interfere). It's not until Kid Buu spits him out that he can help the heroes.
  • Heroes Love Dogs: One of the main causes of his Heel–Face Turn, outside of Mr. Satan, is his pet dog Bee.
  • Heroic Sacrifice: Twice. In Z, he risks his life (and nearly dies) while fighting Kid Buu. In GT, he effectively kills himself by fusing with Uub.
  • Heterosexual Life-Partners: With Mr. Satan. It's Mr. Satan that teaches Buu the value of human life and causes him to recant killing. Mr. Satan also acts as his moral conscious and Buu is completely loyal to him.
  • Hidden Depths: The first non-violent interaction we see Buu have is with a homeless blind child who doesn't recognizes him due to his blindness. Puzzled by the child's lack of fear towards him, Buu first heals his blindness so he can scare him. However, when the blind kid is too much in awe of Buu for having given him the ability to see to be scared of him, Buu discovers that he rather likes being praised for doing a good deed. When the formerly-blind kid reveals that he was actually out searching for milk, Buu decides to help him out further by getting him some milk (albeit by turning the milkman into a carton of milk). This is the first sign that Buu isn't inherently evil, he just sincerely doesn't understand that hurting and killing people is wrong.
  • Hoist by His Own Petard: Tries to turn the Evil Buu into chocolate with his change beam, but is ironically turned into chocolate himself and eaten when the Evil Buu blows his change beam back at him. He gets better later.
  • Hulk Speak: The Funimation dub has him talking like this. In the original Japanese version, he speaks rather normally.
  • Humanity Is Infectious: After becoming friends with Mr. Satan and learning that killing and destroying are wrong, he gives up his evil ways and chooses to live a peaceful life on Earth. The influence Mr. Satan has on him is so powerful that Fat Buu acts as a restraining bolt for Super Buu, preventing him from hurting Mr. Satan.
  • Idiot Savant: Despite the fact that he appears to be...less than intelligent, much like Goku, Fat Buu's intelligence is concentrated more in combat than other areas, giving him the appearance of being less than intelligent. While not exactly untrue, he is known to be quite adaptable and cunning in combat.
  • Idiot Houdini: Buu is allowed to live because he didn't have any idea of the moral implications of his actions. Helps that he becomes pretty much harmless Comic Relief after befriending Mr. Satan and learning empathy and that destruction/killing is wrong. Also the fact that Shen Long brought back to life every human he killed technically absolved him from any homicide he commited. Giving all this, it's hard to find a reason to demand punishment on him by the end of the series.
  • Just Toying with Them: His fight with Super Saiyan 3 Goku is a unique example for this series for two reasons. One, neither Buu nor Goku has an enormous power advantage, so they're both not taking it seriously. Two, while both fighters are actually outputting their full power during the fight (Goku is sweating bullets by the end), they are "holding back" by virtue of not fighting very aggressively. They throw a few moderate attacks at each other, have pleasant mid-battle chats and exchange compliments, and let each other demonstrate various combat tricks. And when they're done, they simply part ways amicably. It's more of an example of two Spirited Competitor types having a friendly (albeit intense) spar than a true life or death battle.
  • Kick Them While They Are Down: He wraps Vegeta in a string of his own flesh, immobilizing him. He then lands on Vegeta, crushing him, before beating the living hell out of him.
  • Lack of Empathy: Starts off this way but learns empathy by interacting with Bee and Mr. Satan.
  • Laser-Guided Karma: Despite being redeemed with the help of Mr. Satan, he still had to pay his dues. Namely, being the weakest and least skilled Buu form, he gets his butt kicked mercilessly by his evil counterparts. He gets turned into chocolate and eaten by Evil Buu, exactly what he did to many of his victims, and later he is overwhelmed and beaten to near-death by Kid Buu, again just like he did to his victims.
  • Laughably Evil: Double subverted, he is a silly enemy, but the power he wields is played straight.
  • Let's Get Dangerous!: When Basil accidentally hurts Mr. Satan, Buu stops playing around and literally beats Basil into the ground. If the rules had permitted ring-outs, he would've won right then and there.
  • The Load: He is by far the least dependable Z-Fighter bar none. Whenever there is a crisis or a need for his power, he falls asleep. This includes him sleeping when he's needed for the tournament between U6 and the Tournament of Power.
  • Literal Split Personality: After he expels all his inner evil he becomes the good side of Buu, thanks to the Kais he absorbed giving him a conscience. This also makes him the weakest form, since Buu was originally a pure evil being created by absorbing the evil energy from across the universe.
  • Living Emotional Crutch: Mr. Satan and Bee (the puppy) becomes this to Fat Buu. He completely loses it when they're shot by a madman to the point that he releases all his inner evil who took the form of Evil Buu. They're also the primary reason he is redeemed.
  • Me's a Crowd: During his fight with Kid Buu, his severed pieces reform as four copies of himself, all of which proceed to beat on Kid Buu.
  • Morality Chain: His presence in Super Buu made him receptive to Videl's challenge (through her relation to Mr. Satan), though it didn't stop him from later killing her. When inside Kid Buu, he kept Kid Buu from harming Mr. Satan until Kid Buu spit him out.
  • Monster Progenitor: In the timeline leading to Dragon Ball Online, Buu spontaneously decides he wants a wife and family after reading one of Mr. Satan's romance novels and creates a wife in the same manner he created Evil Buu, though formed from his desire for love rather than from struggling with grief and anger. He then shoots Miss Buu with a "love beam", causing her to produce kids. That beam would eventually spawn the entire Majin race. Thankfully, they're "monster" in name only, showing none of the original Buu's psychopathic tendencies. Each subsequent generation of Majins also happen to be weaker than the last, though with training and a wish from the Dragon all of these newer Majins have the potential to become as strong as "Pure" Buu.
  • Non-Human Sidekick: To Mr. Satan/Hercule after his Heel–Face Turn. This works out surprisingly well despite Hercule being weak. Buu has always been an almost mindless force, needing someone to give his life and skills direction. Of course, if you are mean and cruel to him, he'll turn on you, just ask Babidi. Hercule, on the other hand, is kind and friendly to Buu, which makes the big guy far more willing to listen to Hercule.
  • No-Sell: When Super Saiyan 2 Vegeta confronts him, he just sits still and lets the guy punch him repeatedly to no effect, even laughing and saying it tickles. That is, until Vegeta uses a charged-up energy attack to blow a hole in his torso; THAT makes him mad, because it it actually hurt "a tiny bit"; he proceeds to give Vegeta one of the worst beatings in the series.
  • Now It's My Turn: One of his ways to fight is letting his opponent ineffectively attack and knock him around, then laugh it off and fight back with devastating force.
  • Obliviously Evil: Does not realize that killing/eating people is wrong until Mr. Satan points this out to him, leading to a Heel–Face Turn.
  • One-Track-Minded Hunger: The number of people he kills without eating them can be counted on one hand.
  • Out of Focus: So much so that it can be easy to forget Fat Buu is allied with the heroes in Super or GT. Though admittedly, in the latter case Buu does get a Heroic Sacrifice while seeming Older and Wiser, in the former.... he's simply The Load. It's telling that when he does get a chance to become relevant, it's Grand Supreme Kai who has control over his body instead of him.
  • Pink Girl, Blue Boy: Inverted in relation to his light blue-skinned wife, Miss Buu.
  • Power Copying: Instantly learns the Kamehameha after seeing Goku use it just once. He also mimicked the Supreme Kai's psychic attack. As Super Buu, it is revealed that he even learned Vegeta's suicide attack (which he can simply regenerate from).
  • Power Limiter: Fat Buu becomes one to both Super and Kid Buu. After Evil Buu ate Fat Buu and became Super Buu, he becomes more powerful but hindered by emotions such as pride, arrogance, and his friendship with Mr. Satan. Once Fat Buu is disconnected from Super Buu, Buu returns to his pure form. Power-wise, he isn't as powerful as Super Buu at his strongest, but he is the most dangerous form of Buu because he has no emotional restraints and can use his power to its fullest. However, despite not being physically connected to Kid Buu, Fat Buu still manages to influence him, keeping Kid Buu from killing Mr. Satan until he finally spits him out.
  • Put on a Bus: In Dragon Ball Super's Tournament of Power arc, he underwent intense training which looked quite promising, since he went from fat to fit and beat Goku with clever tactics and a ring out. Unfortunately, he went overboard with training and ended up taking a two-month "nap".
  • Redemption Demotion: Though certainly still a force to be reckoned with, expelling his evil side puts him at a disadvantage against his Enemy Without, and later Kid Buu. Both of them had no morality to speak of, and thus could use their power to its full extent. Also since Buu is originally an evil, chaotic being, Fat Buu lost most of his power after he expelled his evil side and was rejected by Kid Buu. This, however, does not make him weak. He's still powerful enough to completely manhandle Basil, one of the strongest fighters in Universe 9 and Goku considered him one of his top picks for both tournaments.
  • Resist the Beast: Prior to losing control of his anger and inner evil, Buu desperately screams at Mr. Satan to get away from him before it's too late.
  • Running Gag: Buu falling asleep at inconvenience times. He slept through the entire invasion with Frieza, he fell asleep while taking the test for the first Universal Tournament. He fell asleep during the Zeno exhibition match and he fell asleep again before the Tournament of Power. In most of these examples, he didn't wake up until the conflict is long over.
  • Stone Wall: Actually hurting Buu is a feat onto itself due to his intense durability, stamina, and healing factor. Even weakened by his separation from Evil/Kid Buu, he's durable enough to take multiple blows from freaking Beerus and keep going, something even Goku couldn't do. Severally of his fights consist of him letting the opponent knock him around ineffectively.
  • Story-Breaker Power: According to the guidebooks, his Candy Beam would fell anyone not protected by godly magic (like Vegito). So, of course, he never uses it in Super.
    • Unlike other characters like Gohan and Gotenks who have explicitly become very weak by the time of Super (to the point where Krillin can now be wounded by a bullet if off guard), Buu's power never seems to decay. He's still considered quite strong throughout and is Goku's first choice for the U6 tournament, with the anime Universal Survival arc implying that his default power is around that of end-of-Super Super Saiyan 1 Goku's.note  Such a level of strength in a secondary character would have trivialized most foes between Beerus and Zamasu,note  while the aforementioned Candy Beam would have trivialized the rest.note  So Buu gets hit with a Deus Exit Machina four times in a row.
    • As shown by the last arc of Super, Buu gains power at a ridiculously fast rate, with two hours of training massively boosting his strength and speed according to Goku. He never trains. Notably, his performance in the Moro Arc (against a Moro who required Super Saiyan Blue at the moment to fight) implies the power boost stuck, making him even more this trope.
    • As the Supreme Kai points out in chapter 30 of the Super manga, Buu can heal anyone from any injury and has seemingly bottomless energy, rendering senzu beans irrelevant. If he had participated in the Tournament of Power, not only would he have been one of the strongest fighters there (about on par with SS3 Goku and thus dimensions above 90% of the competitors), but he would have been able to nigh-instantly put any of his teammates back to fighting shape whenever any of them got tired or suffered a wound. He also would of been able to knock out several fights easily thanks to being able to do things like turn them into food, and then throwing them out, with only fighters like Jiren or Top being possibly able to No-Sell it. This would have been massively overpowered, particularly as two major plot points of the Tournament of Power were trying to conserve energy and weaker fighters ganging up on tired-out stronger fighters. So, like in previous arcs, he gets hit with a Deus Exit Machina.
  • Stout Strength: He's essentially a fat blob, but he was one of the universe's greatest threats for a long time and with good reason. The guy once flattened entire cities with a puff of his breath.
  • Super Prototype: According to the backstory of Online, as the Majin race became more numerous, his immense power divided with his lineage. Over time, the Majins weren't that much stronger than your standard Earthling or Namekian (despite Buu himself far exceeding any of the above).
    • Without the wish to erase the memories of everyone on earth (sans Goku’s allies) of his existence? Majin Buu wouldn’t be able to live a normal life on Earth. It doesn’t matter that he decided not to kill anymore after all was said and done; he still killed millions of people, with his other forms outright destroying the planet. Without that wish, nobody on Earth would forgive him otherwise.
  • Sweet Tooth: He's very fond of chocolates and candy.
  • Third-Person Person: Dub only.
  • Took a Level in Badass: After beating Basil in Universe Survival Arc, he desires to fight seriously; thus he's being retrained by Mr. Satan. To the point that he's not fat anymore and he beats Goku in a friendly match with tournament rules, although Goku wasn't really trying either.
  • Took a Level in Jerkass: In Dragon Ball Supers' Battle of Gods arc, Buu acts more in the manner of a jerk than he did in other supplemental material. In said episodes consisting this arc, all he ever does is intimidate Mr. Satan for more food. Come Beerus' visit, not only does he eat all the pudding, he does it after Whis and Mr. Satan politely ask him to share. He then says that since he's strong so he can have whatever he wants. When Mr. Satan tries to apologize for him, Buu pushes him out of the way and attacks Beerus. Although he's nowhere near as dangerous or evil as he used to be and is still a good guy at this point, it's harder to feel sorry for him when Beerus beats the crud out of him. However, this is then followed by the second example below...
  • Took a Level in Kindness:
    • Thanks to Hercule's influence (with a little help from a puppy), Buu gained a rudimentary sense of morality and swore off killing. At least until someone shot Hercule...
    • Despite how he behaved in the Battle of Gods arc, Buu still values Mr. Satan above all else and when offered a bribe to wish for something from the Super Dragon Balls, he says that he'll give the wish to Mr. Satan because Mr. Satan has given him everything he's ever wanted. That's something that couldn't have been said about Buu before his Heel–Face Turn.
  • Ugly Guy, Hot Wife: Buu is a fat, goofy-looking blob monster while his wife Miss Buu is much more conventionally attractive, resembling a gorgeous, buxom woman. Justified in that her appearance was based on one of Mr. Satan's pornographic books.
  • Ungrateful Bastard: Shortly after he was released by Babidi, Buu pretty much ignored Babidi's presence going around and doing his own thing, not even thanking him. He only ends up bowing to Babidi when the latter essentially threatens Majin Buu with being re-sealed if he doesn't accept him as his master.
  • Unskilled, but Strong: He's not as vacant as he looks and can mimic techniques after seeing them once, but he tends to rely on his preposterous durability.
  • Unstoppable Rage: His power rises as he gets angrier, something noted by both Goku and Vegeta. This is implied to be because of him shedding the Grand Supreme Kai's Restraining Bolt influence and gaining more access to the power of Kid Buu and South Supreme Kai. When he gets angry enough, he expels his latest power-up which then forms a whole new being, Evil Buu.
  • Unwitting Instigator of Doom: In Battle of Gods he refuses to share any pudding cups with Beerus. This not only results in Beerus beating the tar out of him, but also leads to Bulma calling on the other fighters present to restrain Beerus and ultimately leads to Beerus deciding to destroy the Earth out of frustration.
  • Vocal Dissonance: Fat Buu's voice in Japanese is surprisingly raspy for a rather ditzy and childish individual, adding to his creepiness factor.
  • Woobie, Destroyer of Worlds: Mainly because it's all he knew to do until Mr. Satan came into his life.
  • The Worf Barrage: His Transformation Ray gets deflected back by Evil Buu.
  • The Worf Effect:
    • His introduction. He knocks out Dabura with one kick (after poking out his eyes), handily demonstrating how much more powerful he is than the previous Arc Villain (Dabura was stated to be Cell's equal). He then nearly kills Gohan with two hits.
    • His fight with Kid Buu is basically this. Keep in mind both forms have almost unlimited endurance and don't seem to mind pain very much, to say nothing of their From A Single molecule regeneration. Yet Kid Buu still overpowers the good Fat Buu, just to send the heroes a message: even a hero Buu is no match for a villain Buu.
    • Happens earlier with Evil Buu. Up to that point, Fat Buu was invincible with only Super Saiyan 3 Goku giving him a decent fight. Then Evil Buu curb stomps him without really trying and deflected his transform ray by blowing it back.
    • The biggest example would be against Beerus, in both the film and Super, where he gets thrashed both times with no effort from Beerus (though he does take the hits better than any other opponent).
  • Worthy Opponent: He comes to see Goku as this since he's the only opponent he fought that he didn't flatten. He's quite upset when Goku stops their match. Goku uses his desire to fight strong opponents to make him wait three days before destroying the Earth. He does not feel this attitude about Vegeta, on the other hand, which may have something to do with the fact that Vegeta is a major Jerkass on top of being much weaker than he.
    Buu: You bad-mouth me a lot for being such a weakling.
  • Would Hurt a Child: Beating Gotenks to the point he had to be medicated and having a black eye.
  • Your Size May Vary: He can go from being nearly as tall as Super Buu or Dabura to just Goku's height depending on the scene. The official height charts for the animators indicate that he's supposed to be huge: over seven and a half feet tall, but as of Super his "Good" self seems to have firmly settled into a shorter height. This makes sense since he's a shapeshifting entity, and the expulsion of his evil persona could also play a part in his change in mass.
  • You Wouldn't Like Me When I'm Angry!: When he gets mad, he stops playing and starts trying to beat whatever angered him to a bloody pulp. Basil is a good example of this: before getting mad, Buu was treating their fight as a fun game, happily tanking everything Basil tried to dish out and just having a blast. When he gets angry because Mr. Satan got caught in the crossfire? Buu manhandles Basil with a brutal beat-down.

    Evil Buu 

Evil Buu (魔人ブウ 純粋悪, Majin Bū Junsui Aku, "Pure Evil Majin Boo")
Voiced by (English): Brian Dobson (Ocean dub); Josh Martin (Z and Budokai Tenkaichi series) Justin Cook (DBZ Kai onwards) (Funimation dub)

"You fool! I'm Majin Buu!"

Fat Buu's evil side, released during Fat Buu's Freak Out when Mr. Satan is almost murdered. Evil Buu fights Fat Buu, turns him into chocolate, and eats him. Thus powered up, Evil Buu transforms into Super Buu.

  • Adapted Out: Because of his limited screentime, most video games don't mention his assimilation of Fat Buu, or when they do, it happens offscreen, making him The Ghost. The Tenkaichi games and Dragon Ball Heroes are notable exceptions.
  • Ascended Extra: His appearance in the manga is so short you barely remember that he was even a thing. In the anime, he goes into an extended fight with Fat Buu and he appears in several games.
  • Attack Reflector: When Fat Buu tries to use his Transfiguration Beam to turn him into chocolate, Evil Buu blows out a cloud of steam that sends the beam back at Fat Buu, leading the latter to turn himself into chocolate instead.
  • Ax-Crazy: Upon his birth, he nukes Van Zant out of existence with a huge smile on his face.
  • Bad Guys Do the Dirty Work: Fat Buu had renounced killing by that point, so he is the one who kills Van Zant after the latter shot Mr. Satan and Bee.
  • Dark Is Evil: The most characteristic trait in Evil Buu. Its color is dark gray and has soulless white eyes within the black sclera which originated the Black Eyes of Crazy trope.
  • Enemy Without: He's Fat Buu's evil side who emerged from within him.
  • Evil Counterpart: He's Fat Buu's opposite in both personality and appearance.
  • Evil Is Bigger: He towers over his good self.
  • Good Colors, Evil Colors: Wears a dark blue cape to contrast with Fat Buu's vibrant purple cape.
  • Grayscale of Evil: His skin is a drab gray in contrast to the pink that all the other forms of Buu have.
  • Lean and Mean: He is the skinniest of all the Buu forms and the second meanest next to Kid Buu.
  • Literal Split Personality: He's Buu's evil personified.
  • Minor Major Character: Doesn't even show up for 10 minutes, and things go From Bad to Worse once he's through. Specifically, he turns into Super Buu, and then into Kid Buu, Buu's original form where he managed to kill off most of the cast.
  • Mirror Self: The polar opposite to Good Buu. He is thin while Good Buu is fat, gray while Good Buu is pink, has a dark blue cape while Good Buu has a vibrant purple cape, and speaks in a deep and gravelly voice in contrast with Good Buu's childlike voice.
  • Nightmare Face: Gives an infamous one with a wide Slasher Smile with bulging eyes as he laughs maniacally when he becomes Super Buu. It particularly stands out with his characterization for the majority of his limited screentime.
  • No-Nonsense Nemesis: The most out of any form of Buu, especially in the manga, after killing Van Zant, he immediately goes after Good Buu, dominating over him in a short bout and eating him quickly after without Evil Gloating or dragging the fight out. This nature would be inherited into Super Buu, especially in the manga.
  • Not So Stoic: Gives a crazed smile and laugh as he turns into Super Buu.
  • Pure Is Not Good: He is the pure evil within Buu's that has taken physical form. The Japanese text even calls him Pure Evil Buu.
  • The Quiet One: The only thing he says is a response to Fat Buu claiming he's the real Buu, calling him a fool and saying that he is the real Buu.
  • Sadist: Takes downright horrifying pleasure in murdering Van Zant.
  • Slasher Smile: After eating Fat Buu, he laughs insanely as he turns into Super Buu.
  • The Stoic: Most of the fight with Fat Buu he never smiles.
  • There Can Be Only One: He very clearly doesn't like the idea of there being another Buu beyond himself. To be fair, neither did Fat Buu.
  • The Voiceless: In the original manga, he is completely silent. The anime gave him two lines of dialogue. The Tenkaichi series and Heroes reduce him to Pokémon Speak.

Voiced by (English): Brian Dobson (Ocean dub); Justin Cook (Funimation dub)

"I'm the terror of the universe."

The combined form of Fat Buu and Evil Buu, with the latter's personality. After tracking down the surviving Z Fighters, Piccolo begs him to wait until Goten and Trunks finish training and merge into Gotenks (so they can put up a more stirring fight), which he does, but kills every person on Earth besides the Z Fighters just because he's bored. Super Buu finally fights and absorbs Piccolo, Gotenks, and Gohan, gaining all of their powers, before Goku and Vegeta fuse into Vegito and nearly pound him to dust — until deliberately getting absorbed to save the others. Once inside Buu, however, Vegito unfortunately defuses. Goku and Vegeta successfully remove their friends from Super Buu's body — along with Fat Buu, whose absence causes Super Buu to transform into the more psychotic Kid Buu.

  • Achievements in Ignorance: Implied. When he was trapped in the Hyperbolic Time Chamber, he goes into a Villainous Breakdown. He screams, causing a tear in the Hyperbolic Time Chamber and when he does this he stares in bewilderment for a few seconds before catching on and gapping it through the hole.
  • Ain't Too Proud to Beg: Practically begs for mercy when Vegeta is about to rip Fat Buu free, telling him that doing so would effectively erase him. Vegeta doesn’t hesitate.
  • And I Must Scream: Piccolo attempts to inflict this on him when he traps Buu within the Time Chamber. Since Buu is an ageless entity, this means eternity in an empty dimension with no way to escape or die since he regenerates even from molecules. He escapes by, well, screaming.
  • Arrogant Kung-Fu Guy: Of all the Buu forms, he fits this the best. Super Buu prides himself on being the strongest in the universe and will throw a tantrum, should anyone surpass him in power. Before he absorbs Piccolo, he is not that well trained, relying on his strength and his regeneration. He becomes much more disciplined once he starts absorbing people.
  • Ax-Crazy: Easily the most psychopathic and most sadistic form of Buu. He laughs insanely as he attempts a "suicide" attack to kill Gohan for starters. He also laughed madly as he turned the surviving main cast into chocolate and ate them.
  • Badass Boast: While laying a No-Holds-Barred Beatdown on Gohan:
    Buu: I possess the greatest powers in the universe! And I'll use them all to kill you!
  • Batman Gambit: Pulled this off with flawless effect against Gotenks.
  • Battle Strip: When Super Buu absorbed Gohan, it created a replica of Gohan's uniform/gi, which is obviously a good guy's outfit. Super Buu, objecting to wearing this, tore the shirt off shortly after absorbing Vegito, expecting a new outfit to materialize. Unfortunately for him, Vegito was NOT absorbed because he protected himself from the absorption process.
  • Be Careful What You Wish For: In an attempt to buy some time for Goten and Trunks, Piccolo suggested that Buu should get back to slaughtering the human race as a distraction. Buu did just that in under two minutes.
  • Berserk Button: Do not deny him his candy. He will get so mad, he'll rip a hole between dimensions…
  • Beyond the Impossible:
    • Leaving the Hyperbolic Time Chamber without using the doorway was supposed to be impossible. Piccolo was counting on this to trap Buu inside in case Gotenks failed to stop him. Instead, he created a portal to the outside by screaming loud enough. It was so impossible, even Buu was surprised. Afterward, the trope is deconstructed: if he could do it then anyone with equal or greater power can do it.
    • Potara Fusion was stated by Old Kai to be permanent and irreversible, who himself was a victim of Potara Fusion. Instead, merely being inside Buu's body after being absorbed apparently caused Vegito to separate back into Goku and Vegeta. When Super rolled around this was politely revised with Gowasu, a much wiser and more experienced Kai from Universe 10, stating that Potara Fusion was permanent only if a Kai was fused, and would otherwise last one hour, and the timing of Vegito defusing inside Buu's body was simply a coincidence.
  • Big Bad: For the middle stretch of the Buu arc, corresponding to volume 41 and the first third of volume 42. Notably, he's the most powerful villain in the Dragon Ball manga, as well as the original Dragon Ball + Dragon Ball Z animes and movies, especially once he absorbs Gohan.
  • Big Eater: And unlike before, it's played very dark.
  • Big "NO!": He does this in the time chamber when he finds out that there is no chocolate or other sweets to eat in there and again when Vegeta tears down the pod in his head containing Fat Buu, spelling his doom.
  • Bishounen Line: As he absorbs more and more people, his bodily features start to become more defined and humanoid. He gets a nose from Piccolo, fingers from Gotenks (in the manga), and a chin from Gohan. Fat Buu also had a case of this, as his sclerae were white instead of black after absorbing the Grand Supreme Kai.
  • Black Eyes of Evil: Black sclera, red irises, all malevolence.
    • Originally his irises were white, and change to red in the manga without explanation from what is most likely an error. The anime makes this a bit more deliberate; when Buu takes a freebie punch he gave to Gotenks, he gives a Slasher Smile and his eyes change color. Some fans believe this is meant to show Evil Buu completely overwhelming any lingering traces of Fat Buu's influence, as after this change he has no qualms eating Videl despite knowing she is Hercule's daughter and then attempts to kill Hercule himself during the fight with Gohan.
  • Blood Knight:
    • The only reason he didn't outright destroy the Earth the moment he was born was due to Goku's promising him a strong opponent to fight. It's implied that this aspect of his personality is influenced by the South Supreme Kai.
    • He freely admits the only reason he didn't (initially) absorb Gohan alongside Gotenks and Piccolo was so he'd have a good opponent to test his newfound power with.
  • Bond Villain Stupidity: Averted on every level. Super Buu is very pragmatic in battle and will not hesitate to kill, eat, or absorb anyone who gets in his way. The worst thing about it is that he does it with a great amount of surprise. No evil laughing, taunting, or mocking. Just straight-up death. The only instances he'll ever draw out a battle is to discover the weakness of his opponents. When he does find out their weaknesses, he will exploit them to devastating effect. Whether it's flaws in power or personality traits of the opponent. Although, he was caught somewhat flat-footed when Gotenks revealed he could go Super Saiyan 3 and would likely have been killed had the fusion not broken apart when it did. Not to mention, he only escaped from the Time Chamber because he threw a temper tantrum, otherwise he would have been trapped in there forever.
  • Break Them by Talking: To Gohan after absorbing Piccolo and Gotenks, using words they would say and his inability to protect them in order to mentally torture him. This is a case of Dub Text as Buu never played mind games with Gohan in the original Japanese version to the extent that the original dub does. Although he does mention Piccolo:
    Super Buu: "Always watch closely your opponent's movements". I thought Piccolo taught you that!
    Gohan: Shut up!
  • But Not Too Challenging: Super Buu is a Blood Knight who didn't destroy the Earth immediately because he remembers Goku's promise of a challenging opponent for him to fight. He also admits that the (initial) reason he didn't absorb Gohan alongside Gotenks and Piccolo is because he wanted a strong opponent to test his new power on. Of course, it's clear that Super Buu's idea of a Worthy Opponent is someone who doesn't die in a couple of hits, and he actually despises the idea of anyone being his equal in strength or being stronger than him. When he's first outmatched by Gohan, he undergoes a Villainous Breakdown and deliberately self-destructs (knowing he can reconstitute his body) so he can wait one hour before putting his plan to absorb Gotenks and Piccolo in motion. When Vegito starts to get the upper hand on him, Super Buu grows increasingly angry and desperate to win, which allows Vegito to put his own plan into motion by letting Buu absorb him so he can rescue all of the absorbed victims trapped inside Super Buu's body.
  • Butt-Monkey: Reduced to this by Vegito, being completely unable to do anything meaningful to the fusion, as the Saiyans dominated the fight humiliating him time and again. However, he totally deserves it for all the monstrous things he did.
    Vegito: It's not much fun being hunted... is it Majin Buu? Being hunted the way you hunted down our friends... Does it hurt!?
  • Can't Kill You, Still Need You: Revealed to be the reason why he didn't kill Gotenks the minute he defused; he needed him for his plan to beat Gohan.
  • Cessation of Existence: When he notices that Vegeta is about to pull Fat Buu out of him, he panics. Hard. Everyone else being removed just made him angry and annoyed. He actually breaks down and begs Vegeta to stop.
    Super Buu: Please! Let go! If you tear those attachments, I won't be me anymore!
    • It's unknown which part scared him more. Effectively not existing anymore or the fact that the mindless Kid Buu would be all that was left. Probably both given he probably wouldn't care about the destruction Kid Buu would cause.
  • Climax Boss: Despite ultimately becoming the most powerful and arguably smartest villain in the Dragon Ball Z canon, he's not technically the Final Boss. That's the much dumber and crazier Kid Buu.
  • Combat Pragmatist: Super Buu will either immediately absorb you if you're stronger than he is or turn you into candy. Gotenks and Vegito can attest to that. Something Vegito was counting on. Goku considers him particularly despicable for this attitude, but Buu disagrees.note 
    Goku: It's not fair... you keep absorbing people!
    Super Buu: Heh heh... you know as well as I do that winning is everything! Well, don't despair. I'll only make you suffer for a little while.
  • Crazy-Prepared: He's a lot smarter than he looks. For example, after he reverts to a weaker form while fighting Goku, he finds himself outmatched again. Then he points to his head tentacle, which had a piece of it cut off earlier...
    Super Buu: [after distracting Gohan with inane conversation for a minute] Luckily, I left some 'insurance' in case this happened. Why do you think I didn't regenerate this? [cue a decapitated piece of Buu jumping out of a rock behind Gohan, absorbing him]
  • Creepy High-Pitched Voice: After Gohan managed to overwhelm him completely, Super Buu swears to get even with Gohan with his voice getting disturbingly high-pitched complete with a Nightmare Face. Compared to his usual deeper tone, the change is jarring and disturbing.
  • Deadpan Snarker: Mostly during his fight with Gotenks, but it shows up in other places as well. This is played up more in the Funimation dub of the anime though, whenever he interacts with Goku.
    Super Buu: I'm sorry. I interrupted you. You were giving a speech. Something about making me answer for my crimes? Honestly, I was finding it a little cliché. Please, continue.
    Super Buu: For your sake, I hope you brought some insurance to back up your claims. But knowing you Goku, you probably don't even know what "insurance" means.
    Super Buu: Oh, don't take it too personally, Goku. Everybody fails. Your failure just means the end of the universe. Sorry about that.
  • Death of Personality: Being essentially a fusion, he is an entirely separate being than the other two main Buus, Fat and Kid. Detaching Fat Buu, according to Super Buu himself, causes him to "cease to exist". While removing Fat Buu doesn't physically kill Super Buu, just reverting him to the pure Kid Buu, it still completely erases Super Buu's mind. Taken to a further extreme when Kid Buu is reincarnated as Uub; Super Buu was only possible via a combination of Fat Buu and Kid Buu, both due to their ki and biology. With Kid Buu's 'soul' being reincarnated in a normal human's body now, Super Buu can never be formed again. Instead of being dead in the afterlife, he doesn't exist at all — he's the only Dragon Ball Z character, outside of Android 16, to be well and truly gone.
    • Majuub from GT could possibly count as a good reincarnation. Like Super Buu, Majuub is a fusion of Kid Buu (reincarnated as Uub) and Fat Buu who is much more powerful than his fusees. Majuub also gains some of Super Buu's tactical intelligence. However, he of course doesn't have anything resembling the same personality, so the original Super Buu is still permanently gone in all continuities.
  • Determinator: "What Buu say, Buu do!"
  • Didn't See That Coming:
    • Super Buu didn't foresee Piccolo destroying the door to the Hyperbolic Time Chamber, trapping him in another dimension. He only manages to escape by luck.
    • While he makes it clear he was waiting for Gohan to arrive, this very nearly gets Buu killed in his fight against Gotenks when he finally turns Super Saiyan 3, as due to this refusal to take his opponent seriously, he ends up being mere seconds away from death.
    • Buu had no way of planning for Goku returning to life thanks to Old Kai. He also couldn't have known that King Yemma would send Vegeta back after he died to Fat Buu, giving Goku the perfect partner to fuse with.
    • Vegito creates a barrier to keep himself from being absorbed into his body and Vegito planned to be absorbed from the start so he can free his family.
    • Vegeta pulling Fat Buu free from his body is something Super Buu didn't see coming.
  • Do Not Taunt Cthulhu: Chi-Chi slaps him and yells at him for supposedly killing Gohan. Super Buu, without even changing his expression, transforms her into an egg and crushes her right in front of her family and friends.
  • Don't Make Me Destroy You: To his credit, he warns you of the trope above not to make him mad. Oh, he'll kill you, unless you amuse him, which only delays the inevitable. But angering Buu proper is something neither you nor he, wants, as he'll tear down the laws of physics around him in a temper tauntrum, causing the destruction of the universe and him along with it.
  • The Dreaded: As the strongest and most intelligent Buu form and the single most powerful villain in the franchise (in his final form) before Super and GT came out, he's this. Just look at everyone's reactions on the Lookout when he shows up. Goku of all people wants no part in fighting him, even after removing all his absorptions. Notably, Goku acts remarkably pragmatic in attempting to get rid of him, begging Vegeta to fuse and trying to avoid fighting him by taking him down with internal sabotage instead. When Kid Buu shows up, Goku reverts back to his normal personality, refusing fusion with Vegeta even after he loses their first battle, refusing to call for back-up even after Gohan is revived, playing rock-paper-scissors with Vegeta to see who fights first, and openly complimenting his opponent. Kid Buu and Fat Buu, he has fun with; Super Buu, he just wants gone as quickly as possible.
  • Dumb Muscle: Compared to Frieza and Cell, he comes across as a brute with a few surprisingly good ideas. This changes once he absorbs Piccolo. There's also the transient form he assumes when all the people he absorbed are taken out of him, where he turns into a musclebound monster (this is the form Kid Buu took after absorbing the beefiest Supreme Kai).
  • Establishing Character Moment: He shows himself to be more ruthless than Fat Buu by turning into liquid and flying down Smitty's throat then expanding his body like a balloon until he explodes. He then flies straight for the Lookout since he can now sense energies.
  • Exact Words: When Buu shows up at Kami's Lookout demanding the Worthy Opponent Goku promised him (Gotenks), Piccolo attempts to stall for time by telling Buu there are still humans left on Earth for him to kill. Buu proceeds to use his Human Extinction Attack to slaughter every last human on Earth, in less than two minutes, without even bothering to leave Kami's Lookout.
  • Even Evil Has Loved Ones: Super Buu still loves Hercule and Bee as friends. He spares the two after his creation in favor of seeking other fighters to go up against. Then, while using an attack designed to wipe out everyone on Earth in two minutes, multiple shots stray towards the two, but always stray off course at the last second as if he physically couldn't bring himself to hurt them.
  • Even Evil Has Standards: When Vegeta threatens to rip Fat Buu out of his body, Super Buu is terrified and begs him not to. Whilst primarily terrified of losing himself as a result, he also uses phrases like "That's the last thing you should do!", implying he's also genuinely scared of what Kid Buu will do without Fat Buu's moderating influence.
  • Evil Counterpart:
    • To Goku. He has certain similarities, such as being a Big Eater, lacking eloquence, being able to quickly learn techniques, and having a tendency to seek a strong enemy, as well as being surprisingly intelligent (especially in regards to combat tactics) despite his crude manner.
    • In many ways he’s one to Vegito, being the result of a voluntary fusion to contrast Buu's forcefully absorbing victims. He's also just as arrogant as Buu, which drives the demon up the wall.
  • Evil Has a Bad Sense of Humor: In the original Funimation dub:
    Buu: Oh, good. I've been looking for a chance to use this. Knock-knock! KNOCK-KNOCK!!!
    Vegeta: Uh, who's there?
    Buu: Buu.
    Vegeta: Buu who?
    Buu: Aww, don't cry. Everyone has to die sometime. (Evil Laugh)
  • Evil Gloating: He's very fond of these after absorbing Piccolo. The Funimation dub has him he use these on top of his Break Them by Talking approach. He rips Gohan apart mentally by bragging how he took his brother and mentor, and how they are upset at him for letting them be absorbed and calls him a failure. When he's ready to kill Gohan, he mocks him for being worthless since his father wasn't holding his hand. Once he takes Gohan after the fusion with Gotenks breaks, he spends several minutes teasing Goku about failing to save Gohan and how his failure meant the end of the Earth.
    • In the manga and original Japanese anime, he eloquently brags about how awesome he is; calling himself "The Mightiest Majin" and making sure his enemies know there's nothing they can do to harm him.
  • Evil Is Bigger: He's the tallest form of Buu, standing at over eight feet, and noticeably towers over everyone he fights.
  • Evil Sounds Deep: Deeper than Fat Buu and Kid Buu, at least. In the English version specifically, his voice gets much deeper after he absorbs Gohan and Piccolo. Justin Cook gives him a deeper, more menacing voice right off the bat in the Kai dub.
  • Expository Pronoun: In the Japanese version, his speech is initially rudimentary like Fat Buu's, but absorbing Piccolo's brains makes him more eloquent and switch from "ore" to the more formal "watashi" (even though Piccolo himself uses "ore").
  • Fatal Flaw: Like almost all the major villains, his Pride. Unlike most, however, Buu is usually smart enough not to allow his pride to get in the way of the more pragmatic solution, like trying to kill Goku and Vegeta before they can fuse, despite thinking it wouldn't make a difference. At the same time, Buu either kills or absorbs anyone who challenges him as being the strongest in the universe, something Vegito used to his advantage to get into Buu's body to save his friends. This eventually leads to Super Buu being undone.
  • Faux Affably Evil: One feature that sets him apart from his other forms. Super Buu can be talkative and vaguely reasoned with, even conversing with his opponents for fun. However, he is extremely cruel and brutal to anyone not on his level of power.
  • Flaw Exploitation:
    • Super Buu exploits Goten and Trunks' stubbornness, arrogance, and pride to trick them into fusion into Gotenks, as a Super Saiyan 3 no less, and then proceeds to absorb them. He even notes that there is a time limit to how long Goten and Trunks can stay fused and declares that he will make quick work of Gohan, which he does.
    • Gohan is called out for his lack of situational awareness and combat instincts more than once in the manga. Buu takes advantage of this to lay a clever trap with his head tentacle, leading to Gohan being absorbed. In the anime, Buu toys with Gohan by taunting him with this after absorbing Gotenks and Piccolo.
    • It's heavily implied that Super Buu did this during his battle with Gotenks, exploiting Super Saiyan 3's poor stamina to win despite his power disadvantage. Halfway through their fight, Buu hides in a crater created by Gotenks and masks his ki, making Gotenks think he was dead. A frustrated Gotenks, not sure if he's really dead, then off-handedly mentions that he only has a few more minutes left of this form after Buu made him wait around so much. Immediately after, there's a Reaction Shot of a surprised Buu, followed by a Beat of Gotenks with Buu off-screen, and then Buu blasting out of the crater back into the fight. After he absorbs Gotenks, the first thing he says before fighting Gohan is that he'll try to kill Gohan quickly because Gotenks' Super Saiyan 3 form causes him to lose energy at a rapid rate, showing further awareness of this weakness.
    • In the same vein, Vegito exploits this back at Buu himself, exploiting his pride in his strength to get absorbed, where Vegito has a chance to attack him from the inside out.
  • Foil: To Goku. Despite their many similarities in personality, they could not contrast more sharply in methods and goals. Super Buu uses his vast power and intellect to sadistically torture and murder any competitors, prematurely if he can. Goku, despite his love of combat, dislikes killing and hurting people who can't fight back, and LOVES his enemies growing strong enough to challenge him (or stronger) for the purpose of self-improvement. This is epitomized by their respective reactions to their only true combat losses of the arc. Goku wishes his opponent to be reincarnated as a good guy so they can have a rematch under friendly conditions. Super Buu throws a temper tantrum and nearly destroys the entire universe just to spite his opponent.
    • To Fat Buu as well, for much the same reasons. This is emphasized more in the original Japanese audio, where Fat Buu and Super Buu have the same voice actor, showing that they're split personalities of the same person.
  • For the Evulz: Though, unlike Kid Buu, Super Buu was at least a bit more interested in fighting a strong opponent rather than random destruction (the first thing he does is fly to Kami's Lookout and demand to fight the "strong opponent" he was promised). The second thing he did is kill every human on earth in one attack because he was bored.
  • Genius Bruiser: Not only is Super Buu extremely powerful, but he Out-Gambitted everyone (though mostly because even before he absorbed Piccolo he tended to act much stupider than he actually was) and it wasn't just a basic case of Super Buu outsmarting them or getting lucky, he covertly came up several plans to become the strongest in the universe and with every plan he came up with, he thought of several back-up plans as well. He also manipulated many of the heroes into making himself seem like less of a threat and when the opportunity presented itself from the heroes being arrogant, he would not only take advantage of it but also made sure that there were some contingency plans if things were to go against him. And it worked like a charm because he technically never loses a battle. And any battle that it seems like he is losing, he's losing on purpose because it's all a part of his plan. It took the Story-Breaker Power of Vegito just to slow him down. Although in the case of Vegito, he was purposely prolonging the battle so he could be absorbed and rescue the others taken by Buu. Otherwise, he would have killed Buu easily. Also, while it's not really elaborated upon, he was able to accurately calculate the entire planet's population just by walking around the Lookout for a minute and then mentally sort through billions of unique ki signatures in order to only kill who he wanted to. It's later revealed that in this form Buu has two gods absorbed, who presumably add a ton of mystical and universal knowledge (though Super Buu never uses it).
  • From a Single Cell: In this form, it's revealed that even if his solid form is destroyed, he can reconstitute himself from his own smoke particles. Every particle at the molecular level has to be destroyed to end him. That said, the anime implies there are mental limits to this, as during the fight with Vegito he gets wrecked so hard that at one point Vegito flat-out points out he hasn't been regenerating several previous injuries and Buu is shocked to realize he's right before quickly focusing and repairing them.
  • Hidden Depths: It's only done for the sake of a joke, but Super Buu is shown reading a magazine about cars in the time chamber while waiting for Gotenks to get through his routine.
  • Hulking Out: The "Ultra Buu" form he takes between losing his Super Buu form and reverting back to Kid Buu is a result of absorbing the South Supreme Kai eons ago. It rendered him an ogre-like berserker who beats on his chest and roars unintelligibly. However, because Fat Buu was actually the Buu who had part of the South Supreme Kai in him, he did not retain this state and it was just a holdover that wore off before he fully changed back into Kid Buu.
  • Humiliation Conga: His entire fight with Vegito. After absorbing Gohan, Buu was close to being invincible. Then Vegito came and made an utter fool out of him. Vegito didn't even need to go Super Saiyan (in the anime at least) and he beat Buu as a piece of candy.
  • Hypocrite: After getting his butt beaten by Vegito, Buu says Vegito cheated by fusing together. This coming from the same person who absorbed Gotenks, Piccolo, and Gohan and bragged about it. Vegito points out the hypocrisy by saying that Buu ate his sons to become stronger. Doubles as an Ironic Echo.
  • Invincible Villain:
    • He never technically loses a fight. 18/Krillin/Yamcha/Tenshinhan, Piccolo, Super Saiyan 2 Vegeta, Super Saiyan 3 Goku, Super Saiyan Gotenks, Super Saiyan 3 Gotenks, and Ultimate Gohan note  are all easily defeated by him via various methods, ranging from Batman Gambit to sneak absorption to straight-up brute force. Even Super Vegito doesn't actually beat him, despite possessing the capability to; he gets absorbed intentionally in a gambit to free his friends, but this ends up backfiring when he defuses due to Buu's Bizarre Alien Biology note , and Super Buu subsequently stomps Goku and Vegeta apart, mostly because they can't kill him inside his own body where they're the size of insects. In the end, he's taken down by internal sabotage, when Vegeta yanks out Fat Buu's pod just as Super Buu is about to kill Goku.
    • Epitomized during his fight with Gotenks; Gotenks blows him to smithereens, then goes around and vaporizes all of the pieces to keep him from regenerating. Buu reforms from the smoke.
    • Though, it's abundantly clear that Vegito had absolutely let him win (the guy gave him a countdown for death). If he was serious, he could have destroyed him mere moments after transforming into a Super Saiyan. Not to mention he only won by luck against Gotenks, whose fusion broke seconds before he could kill him.
  • Jerkass: He's extremely aggressive and confrontational.
  • Just Toying with Them: Does this repeatedly in anime filler, like just about every Dragon Ball villain. Notably and uniquely averted in the manga.
    • He spends almost an entire episode beating SS2 Goku and SS2 Vegeta after he absorbs Gohan before finally deciding to kill them, even though he's powerful enough to smite them in an instant at this point. Judging by the number of power-ups he did against Vegito in the next couple episodes,note  it's implied that the power he used to beat them up was far below even his base, non-absorbed form. In the manga, Goku and Vegeta just fused instantly, so he never got the chance to touch them- and if he did there's no reason to believe that he wouldn't have just killed them immediately like he said he would.
    • He does the same thing when fighting SS2 Vegeta and Goku again inside his body in his base form, smiling the whole time, letting himself get blown apart by attacks even his weaker fat form had no trouble tanking (while laughing), and even explicitly saying that he's playing around midway through the fight. He only goes for the kill after Goku and Vegeta are both too injured/exhausted to provide any more entertainment, by which point it's too late. This entire sequence is filler- in the manga, Vegeta went straight to ripping out Fat Buu's pod before Super Buu could do anything.
    • Gotenks-Buu in the manga says he's trying to kill Gohan from the start and demonstrates this by instantly locking Gohan in a ki restraint and shooting an amplified Kamehameha at him as his first move.note  In the anime, he drags out the fight far more. This case is at least more justified than the previous two, since unlike those, he didn't have any reason to believe that he needed to get things done quickly.
  • Karmic Death: Well, Karmic Death of Personality, but after mercilessly and sadistically tormenting and killing the entire populace of Earth and followed by the Z-Fighters' loved ones, he is reduced to being terrified and begging for his own life the moment Vegeta grabs hold of Fat Buu, the one absorbed being that provides his current sociopathic personality and what keeps from regressing to the thoughtless Kid Buu. Vegeta has no qualms about ripping Fat Buu away from Super Buu's body, which effectively erases his personality, "killing" Super Buu and reverting him back to Kid Buu. Furthermore, Vegeta was one of his earliest victims and Buu was personally responsible for killing his wife and absorbing his son.
  • Kick the Dog:
    • He turned Chi-Chi into an egg and then smashed her for annoying him.
    • He ate all of Goku's friends on Kami's Tower (except Dende) after he escaped from the Hyperbolic Time Chamber. Then he gloated about it to Gotenks when it's revealed Bulma was amongst the victims and later on Gohan while patting his stomach.
    • Two exclusive to the Funimation dub: Once he has Gotenks and Piccolo absorbed, he verbally breaks down Gohan by laying down the guilt of failing to protect them. Then after absorbing Gohan, he rubs in Goku's face about his inability to save anyone, not even his own son.
    • A very subtle one in the anime, when Mr. Satan and Bee attempt to stop him post his Piccolo/Gotenks absorption from killing Gohan, Buu was slowly preparing to kill them, showing how his absorptions had caused him to no longer view them as morality pets.
  • Kick the Morality Pet: A very subtle one in the anime adaptation, Super Buu had spared Mr. Satan and Bee as well as initially listened to Videl, the daughter of Mr. Satan due to the influence of Good Buu restraining him from harming them (though being Hercule's daughter wasn't enough to save Videl from being eaten). After absorbing Gotenks and Piccolo, he slowly prepares to kill them before Gohan stops the attack before it commences. A notable instance to show how far gone Super Buu had become.
  • Knight of Cerebus: The first thing he does is pour himself down a gunman's mouth till he popped like a balloon, and it goes downhill when he manages to wipe out almost all of humanity with one attack, specifically the only ones that weren't affected were by morality, strong enough to dodge the attack or being on Kami’s lookout at the time. He then kills every last one of Goku's friends while Gotenks is trapped in the Time Chamber by turning them into chocolate and eating them. He goes so far as to murder Chi-Chi right in front of her son and brag about it later. It's also notable that, while the likes of Cell, Frieza, and various minor villains constantly reappear in the anime and movies to get humiliated, Super Buu never shows up again past his own arc in any material except games (bar flashbacks and hallucinations, where he's treated as The Dreaded).
  • Know When to Fold 'Em: After turning Vegito into a jawbreaker, only to get humiliated and thrashed by him since Vegito managed to retain his ability to move, Super Buu reluctantly decides to change him back, realizing that trying to eat him is no longer worth the trouble because he’s too fast and small for him to catch and hold on to for long.
  • Knuckle Cracking: Cracking his neck is practically his Catchphrase.
  • Laser-Guided Karma: He is one of the vilest characters in the entire series, second only to Frieza and King Piccolo. He also goes technically undefeated since he absorbed anyone stronger than he was and Vegito threw his fight. This is why it is somewhat fitting that he is the only villain until Super to be erased. After Vegeta pulled Fat Buu free, Super Buu dissolves away, reverting Buu back to his original form who has a different personality. Once Kid Buu is killed, he is reborn into Uub, meaning that Super Buu can never return in any form in this world or the next. A fitting end to such a Jerkass.
  • Laughably Evil: Despite being the most serious and devious of the Buus, he still has some good scenes like this, like freaking out when he gets trapped in the time chamber, or boredly drinking a soda and reading a magazine while Gotenks tries to make a big speech.
  • Light Is Not Good: Very light in color, but not good.
  • Logical Weakness: Assimilating others helps Buu grow stronger by gaining their powers, abilities, and memories. However, this also forces Buu to absorb their weaknesses, too—both physical and mental. His absorption of Gotenks gave him a major power boost, but that only lasted as long as their fusion limit, at which point he was left with the far weaker Goten and Trunks. In addition, because his absorption process bases itself off of who the strongest person he absorbed was, his power drastically weakens when Gotenks defuses because the next strongest person he has is Piccolo, who he had absorbed because he wanted his intelligence. If not for him absorbing the even stronger than Gotenks Gohan, Goku was confident that Gohan could defeat him.
  • Loss of Identity: Invoked; he's well aware that without Fat Buu's presence in his body, the Buu that he is will completely stop existing in any form. This idea leaves him legitimately terrified, causing him to outright beg Vegeta not to free Fat Buu.
  • Lost Food Grievance: The entire reason he was able to escape the Hyperbolic Time Chamber after Piccolo blew up the entrance. He was horrified at the thought of never being able to eat candy again.
  • Loves the Sound of Screaming: After seemingly defeating Vegito, he proceeds to go on a massively destructive rampage through West City in celebration. During said rampage, he openly wishes that he didn't kill every last human on Earth earlier, as destroying things isn't as fun when he can't hear his victims' screams.
  • Manipulative Bastard: Super Buu's surprisingly high intellect and cunning caught a lot of people off-guard in the Buu Arc as he ran rings around the protagonists, making himself look much stupider than he truly was to put the heroes in a false sense of security and then strike when they weren't expecting it. It got to the point where he was acting like the The Chessmaster and was playing his opponents like pawns.
  • Moral Event Horizon: In-Universe - Gotenks didn't take Buu seriously, despite him killing 80% of the planet during his rampage. Even the more ruthless Super Buu who crushed Goten's mom after transforming her into an egg wasn't enough to make Gotenks be serious. It's not until Buu ate everyone on the Lookout, including Trunks' mom, that Gotenks became righteously pissed and swear to kill Buu for everything he has done, only for Gotenks to go back to not taking it seriously when he re-fuses in an effort to show off his fusion to Gohan which promptly gets him absorbed.
  • Moral Myopia: When Goku gets mad at him for constantly absorbing people (most recently Gohan) to get stronger, he claims that he's simply doing whatever it takes to win. When he finds himself getting toyed with by Vegito, he complains how unfair it is that Goku and Vegeta fused together, leading Vegito to point out how absurd this sounds coming from The Assimilator.
  • Near-Villain Victory: Probably the closest example in the whole series. After enacting Plan B and taking Gohan off guard to absorb him, Buu has basically won. Every member of the cast is either dead or absorbed, except Goku, who is completely incapable of opposing Buu in any way, and is so desperate that he considers fusing with Mr. Satan, even though he knows it would be pointless and Buu would still be capable of killing him in one punch. On top of that, he goes straight for the kill, which Goku can only slightly delay by teleporting to the other side of the planet. Luckily for the universe, King Yemma brought back Vegeta giving Goku some fusion fodder, triggering the series of events that lead to Super Buu's reversion into Kid Buu. But if Vegeta hadn't been sent back or, hell, had even been five seconds late, the series would have ended on a very depressing note. This even more so the case retroactively, after Super revealed that he could have killed Beerus without ever meeting him just by killing Kibito Kai and Old Kai (both whom are linked to Beerus)... which Buu was going to do, according to the Old Kai himself.note  No one would have been willing or able to stop him.
  • Nightmare Face: Several insane expressions and facial deformities that make him quite disturbing.
  • No Challenge Equals No Satisfaction: Much like Cell, he sees himself as the strongest in the universe and wants to test his ability against strong opponents. Anyone who can't provide him with a challenge is immediately killed. At the same time, he only wants to fight people he knows he can beat. When fighting against an opponent who completely outclasses him like Ultimate Gohan and Vegito, he has a breakdown.
  • No-Nonsense Nemesis: His first move (after gruesomely killing a bystander) is to fly straight to Kami's Lookout and demand that Piccolo present the "worthy opponent" that he had been promised (Gotenks). When Piccolo tries to stall for time by pointing out that there are people left on Earth for Buu to kill, Buu immediately annihilates just about every bystander left on the planet Earth with a Beam Spam called the "Human Extinction Attack", to the horror of everyone. He then demands, with no further distractions, to see his opponent. He later declares that even if Goku were to fuse with Gohan or Vegeta, they still couldn't defeat him, but then immediately adds that he isn't going to take any chances and will just kill them now to be certain. His big mistake, in the end, was to humor Goku by giving him 5 seconds to merge with someone since he fully believed it was futile. He had no way of knowing that Vegeta would return.
  • No-Sell: He'll do this when he feels it would be more intimidating than letting himself get blown apart only to regenerate. He stands boredly while Gotenks attacks him, at least until the latter pulls out the Kamikaze Ghosts and later Super Saiyan 3. A powerful sneak attack by Super Saiyan 3 Goku in the anime also does absolutely nothing to Gotenks-Buu, despite how effective sneak attacks normally are in this series, hinting at the massive disparity in their powers.note 
  • Obfuscating Stupidity: He appears to be a mere brute, but in reality he was playing everyone the whole time. The act was quite effective too, given that in the original manga, Gohan outright calls him a "retard", and is completely taken off guard by Buu's plan. That said, he did legitimately rely more on brute force and regeneration before absorbing Piccolo, and only used his backup plans when it was clear he couldn't win with those alone.
  • Oh, Crap!: When Vegeta severs his connection to Fat Buu, which causes him to regress to Kid Buu.
  • Orifice Invasion: The first thing he does is liquefy and pour himself down Smitty's throat until the guy pops like a balloon. We aren't dealing with the big silly fat man anymore. He tried it on Vegito, but it backfired when Vegito proved strong enough to compress Buu into a ball inside his own body.
  • Out-Gambitted
    • Super Buu out-gambits everyone to the point he could be the trope image. He out-smarted Piccolo by killing everyone on the planet when Piccolo suggested he amuse himself with the survivors to buy more time so Trunks and Goten could train, calculating the entire population in seconds to do so. He recognized Piccolo's attempts to stall him both on the way to the time chamber (noting that they passed the same landmark twice) and right before entering (when Piccolo offered him food, he declined and outright said "you're stalling"), forcing Piccolo to cut both attempts short. He defeated the more powerful Gotenks by outlasting his Super Saiyan 3, which Piccolo thought could kill him, by hiding and masking his ki for a good chunk of the fight until Gotenks let it slip that he only had two minutes left. He escaped certain death at Gohan's hands by initiating his self-destruct near Piccolo and the kids, forcing Gohan to abandon the battle to save them, and then lowered his ki and regenerated far away. He used Gotenks' arrogance against him to convince him to fuse, distracted him with insults while carefully maneuvering a piece of goo to take him off guard, and absorbed him along with Piccolo to create the nearly invincible Super Fusion Buu that wrecked Gohan. He recognized Gohan's attempt to stall out the fusion immediately (having used the same trick himself), and stated he would finish the battle as quickly as possible while always physically verifying Gohan's presence and never falling for the "masking your ki" trick. When Goku showed up, he made sure they couldn't fuse and when his time ran out with Gotenks, he set up a back-up trap to absorb a distracted Gohan, becoming even more powerful. His only real failure was not killing Goku and instead humoring him to merge with someone, as the only people left then were Dende and Mr. Satan. Then again, how could even he predict Vegeta would come back since he died earlier against the much weaker Fat Buu.
    • Even though he is the Chess Master, even Super Buu has been out-gambitted. He was nearly killed by Gotenks' Kamikaze Ghosts, twice. The first time when he arrogantly hit one, thinking it was harmless, and the second when they tricked him into lowering his guard (though both times he knew he could regenerate, so it's debatable how much danger he was in). Piccolo also one-upped Buu by trapping him in the time chamber by blowing up the door and Buu only escaped because he threw a tantrum that broke dimensions, something that surprised even Buu. Finally, he fell for Vegito's trap hook line and sinker. Vegito's plan was only spoiled because he de-merged. So despite all his planning, Super Buu was nearly done in several times and managed to get by on luck, much like the heroes.
  • Out of Focus: From a meta-perspective, similar to Cell: despite being the most powerful and effective of Buu's incarnations and lasting much longer than Kid Buu (and about as long as Fat Buu) as the Big Bad, he gets the least amount of focus in modern media of any Z Big Bad outside of the movie villains (and even then...). Part of this is due to the Deader than Dead nature of his defeat: he neither gets resurrected as a villain (like Frieza in filler/movies/Super/GT/games or Cell in filler/GT/games) nor does he become a member of the supporting cast (like Piccolo, Vegeta, the Androids, Fat Buu, and eventually Uub). But even independent of that, he's the most likely to get left out of merchandise and games of Buu's three main forms. He doesn't appear at all in Dragon Ball Fighter Z while both Fat and Kid Buu do (both of them even taking his moves), usually doesn't get his various forms when he does show up in games, and is barely referenced after his demise while Kid Buu is referenced constantly in both GT and Super (though In-Universe this is probably because the characters themselves have no reason to make a distinction and just classify the two as the same being- not exactly incorrect either). The only time there is a reference to him are in very, very brief flashbacks/dream sequences. On top of that, in the Xenoverse series he plays a very small role in the story, only gets his base form represented (plus his Gohan-absorbed form in a piece of DLC in 2), and isn't featured as a mentor option (meaning he misses out on increased character interaction and personality tidbits), which even Bit Characters such as Zarbon and Bojack got. Even the Heroes game and promotional material excludes him in favor of more screen time and What If? forms for Kid Buu.
  • Painful Transformation: When Super Buu is forced to revert back to his original form after Vegeta tears Fat Buu from his body, he spends several minutes screaming in absolute agony. It's hard to say if the transformation was more mental than physical, but chances are it's a little bit of both.
  • Polite Villains, Rude Heroes: After absorbing Piccolo, he becomes more well spoken and politer, especially compared to the playful and cruder Vegito. This goes into Faux Affably Evil since it makes him crueler and more sadistic.
  • Pride: Like so many villains, he takes a lot of pride in being the strongest in the universe and won't allow anyone who is stronger than he exist. This eventually leads to his downfall.
  • Psychopathic Manchild: He starts throwing a tantrum when things aren't going his way. Like when he finds out there's no candy to eat in the Hyperbolic Time Chamber, or when Vegito is whooping his ass.
  • Psychotic Smirk: He's prone to this, doing it almost as often as the Slasher Smile.
  • "The Reason You Suck" Speech: In the Funimation dub Buu brutally takes Gohan apart using the memories of Piccolo, Goten, and Trunks to tell him why he fails as a hero and is a disgrace to Piccolo's teachings. Probably the most biting comment is Buu telling Gohan that he's nothing since his dad isn't holding his hand.
  • Red Eyes, Take Warning: Initially, Super Buu is shown with eerie and pale white eyes, but after Gotenks punches his face a few times in the Hyperbolic Time Chamber, he gets angry and they erupt into a permanent red color, and apparently his tongue goes from being pink to a more demonic blue. It was originally an animation error where Akira Toriyama had to point out that the animation team was miscoloring Buu's eyes (and tongue), but in Dragon Ball Z Kai, the moment his eyes go red is edited into a Marked Change where Super Buu's fairly recent evolution from Evil Buu after integrating Fat Buu finally solidified and he became that much more sinister-looking as the evil side fully took over and pushed out the good.
  • Sadist: Unlike Fat Buu, who doesn't know or care about pain, due to his heightened intellect, especially after absorbing Piccolo, he understands how to cause the greatest pain both physically and more importantly psychologically as seen with Gohan with his breaking speech. He took joy in absorbing Gohan in front of Goku and then mockingly calling him dad. He also rubs Goku's inability to save anyone in his face. As mentioned earlier though, all of these examples are Dub Text as Buu doesn't play mind games to this extent in the original Japanese dialogue.
    • Part of what makes this version of Buu so utterly terrifying is how creative he can be when it comes to killing people. When Van Zant's flunky Smitty shoots Super Buu with a machine gun in a fear-induced frenzy, Buu hysterically laughs off the attack... then proceeds to liquefy his body and dive into Smitty's mouth and expand inside his body until he explodes. Buu could have just as easily killed him with an energy blast or even a flick of the wrist, and he went for the most painful and ignominious option.
    • Another example sees him declare that the hopelessly outmatched Gohan is going to "entertain" him as long as he has time remaining (before Gotenks' fusion runs out). He then proceeds to draw out the fight in favor of relentlessly beating Gohan to near death.
  • Shoot the Medic First: Immediately attempts to kill Dende after he sees him healing Gohan.
  • Slouch of Villainy: With or without a chair, Super Buu has terrible posture. His iconic pose is a standing slouch, shoulders slumped and head cocked to one side as he regards his foes with amusement, boredom, or some combination of the above. It serves to indicate his Rubber Man nature and to set up a striking contrast between his rude, crude, Lower-Class Lout attitude and the more strait-laced, aristocratic villains of previous arcs (who carry themselves much more rigidly).
  • Smarter Than You Look: Even before absorbing Piccolo and getting his intelligence, Super Buu was far more intelligent than he let on, with several of the Z-Fighters often dismissing him as Dumb Muscle before realizing they had been Out-Gambitted. Case in point: when Buu showed up on Kami's Lookout demanding the Worthy Opponent Goku promised him (Gotenks), Piccolo tried to stall for time to give Goten and Trunks time to perfect the Fusion Dance by telling Buu to go out and keep terrorizing and killing humans, knowing the Dragon Balls can be used to revive everyone who dies. While Piccolo expected Buu to fly across the world and personally kill every last human himself, Buu instead uses a Beam Spam attack to wipe out every last human on Earth in the span of a few minutes, without even leaving the Lookout as he did.
  • Smug Super: After absorbing Gotenks, he took his time picking apart Gohan both physically and mentally since he knew Gohan would be helpless before him. He gets even smugger after absorbing Gohan, going as far as to let Goku try to merge with someone since he is certain that he is invincible.
  • The Sociopath: Yes, on par with Frieza and his sociopathy seems to grow as it absorbs warriors, especially when he absorbs Piccolo. He has different strategies to cause physical and (in the dub) psychological pain to other beings.
  • Super-Scream: He can scream so loudly it tears holes in the fabric of reality. At one point he does this to the point that the Kais fear a chain reaction that could collapse the universe will result if he tears through too many dimensional barriers at once. Fortunately Vegito stops him before it goes that far.
  • Super-Senses: He walks around the perimeter of Kami's Lookout, and then uses the Human Extinction Attack. Meaning he not only sensed and calculated the population of Earth in one minute, he perfectly tracked every single sapient being on it with his ki sensing and perfectly placed billions of blasts directly through their torsos. While still remaining precise enough to not damage the environment or hurt anyone he didn't want to (like Satan).
    • He's able to recognize Videl as Satan's daughter by her scent.
    • His ki sensing skills are implied to be particularly potent even compared to practiced masters like Piccolo. He was the only one able to sense Gohan's power steadily growing in the Sacred Realm of the Kai, and the only one not surprised when Gohan showed it off later. Buu had planned for it.
  • Suspiciously Similar Substitute: Zigzagged. Once Super Buu absorbs Gotenks, Piccolo, and especially Gohan, he becomes one to Perfect form Cell. He becomes a proud, arrogant Challenge Seeker who thinks no one can best him, and throws temper tantrums when he is.note  However, even in this state he celebrates like a silly child after "winning" his fight with Vegito, takes a break to stuff his face with sweets before destroying the Earth, and excitedly does a happy dance upon finding some; goofy behavior more in line with the previous Buus than Cell.
  • Sweet Tooth: He turns his victims into sweets and until Vegito, it usually spelled the end of his enemies. In fact, he warps reality to get out of the Hyperbolic Time Chamber in order to get more food.
  • To Serve Man: But not before turning them into candy.
  • Underestimating Badassery:
    • One of the reasons Gotenks lost the battle was his refusal to take Buu seriously until the very end.
    • Super Buu in turn doesn't take Gotenks seriously in their final battle, as he later explains he was waiting for Gohan, but nearly ends up being killed by them as a result. He survives by dumb luck.
    • He vastly underestimates just how strong Gohan would be, and suffers greatly at his hands during a rather brutal Curb-Stomp Battle.
    • He in turn calls Vegito a Paper Tiger, certain that he can easily defeat the fused Saiyan. He was very, very wrong.
  • Unskilled, but Strong: He is more skilled than Fat Buu since he is able to sense energy and is more intelligent, however, he still heavily relies on his regeneration and power to get ahead. He becomes much more skilled after he absorbs Gotenks, Gohan, and especially Piccolo.
  • Viler New Villain: Contrasting the more sympathetic Fat Buu, Super Buu is portrayed as an unsympathetic villain who enjoys the destruction he causes and knows what he's doing is wrong but doesn't care, as opposed to Fat Buu who doesn't know.
  • Villainous Breakdown
    • He has a minor one once Gohan returns and beats him using only physical attacks. He gets really mad when Gohan calls him Majin Bo Bo (retarded in the Japanese text).
    • Forced into not just one, but several spectacular ones by Vegito. In the anime, one of them nearly breaks the universe.
    • When Vegeta is about to pull Good Buu free from his pod, he flips out and begs Vegeta not to, saying that he won't be him anymore. Vegeta does so and Super Buu is gone, becoming Kid Buu.
  • Villainous Glutton: Even more than Fat Buu, and unlike with the former, it's played very darkly.
  • Villain Respect: Piccolo is a weakling at this stage of the series and everyone points it out, including Buu himself. However, he still decides to absorb Piccolo in addition to Gotenks because he considers the Nameless Namekian to be valuable for his brainpower. Most likely he decided that based on the various tactics that Piccolo used to stall him,note  the trap he set in the time chamber, and the instructions he gave Gotenks, who he coached during the fight. Even if Buu outplayed him at every turn, he clearly left a good impression on the djinn. This also shows that, despite appearing to be Dumb Muscle, Buu is perceptive and values attributes other than raw power.
  • Villainous Valor: Unlike most other villains, he starts out below the heroes. He finds himself outmatched by Gotenks once he gets serious and is completely beaten down by Gohan after he gets his power-up. He gets around this with deception and a few surprisingly good plans in which he absorbs anyone stronger than he is.
  • Villains Out Shopping: Zigzagged; he gets bored with no-one around (the heroes are trying to figure out how to make a successful attack against him when their inside of him, and he has no idea about it), and decides to get a snack at a bakery, saying, "no sense destroying the world on an empty stomach". Well, he doesn't pay for anything, but then again, the bakery and the town itself is deserted since he killed every last human on Earth earlier.
  • A Wizard Did It: A case where he was the "wizard". Before Dragon Ball Super revealed that Potara Fusion has a time limit for mortals, the only explanation anyone, including the Supreme Kais, had for why Vegito defused while inside Super Buu was 'Buu is magic/filled with all sorts of nasty stuff' (an explanation that was wonky even in the original text, as it's noted in-universe that the Fusion Dance works in Buu).
  • Woobie, Destroyer of Worlds: In a sense. He was born because Fat Buu experienced something traumatic after changing his ways, and since he and Fat Buu are one and the same and thus have the same memories and experiences (as demonstrated by him having memories of Mr. Satan, Goku, Gohan, and Gotenks), he's technically a Tragic Villain. Not that this excuses any of the evil things he does of course.
  • The Worf Effect:
    • Super Buu, who is far more powerful than Fat Buu, gets his butt kicked by Gohan after he gets his major power-up. The same Gohan that Fat Buu easily defeated.
    • After he absorbs Gotenks, Piccolo, and Gohan, he is close to invincible and becomes, at that point, the strongest being in the history of the franchise. Then Vegito comes and makes a complete pansy out of him. It's one of the most one-sided battles in the series. To add insult to injury, Vegito only needs one Super Mode transformation out of three to do this (which at this point in the series is basically not even trying).
  • Worthy Opponent: Much like Cell, Buu's idea of a worthy opponent is someone who doesn't die in a couple of hits. He despises anyone being his equal or, god-forbid, stronger than he is.
  • Would Hurt a Child: He had no problems fighting Goten and Trunks or turning Krillin and 18's infant daughter Marron into candy and eating her along with the rest of Goku's friends.
  • Xanatos Speed Chess: Super Buu is very good at doing this, despite being a mere thug in personality. He noticed Gohan's growing power, so he fought against Super Saiyan 3 Gotenks and tested the limits of his strength and his weaknesses (e.g. fusion limit). After briefly fighting Gohan and finding himself overwhelmed, he goes through an intentional Super-Power Meltdown, knowing he will regenerate and buys time (and getting Goten and Trunks to recuperate, to fuse again). When he returns he goads Goten and Trunks into fusing again at full power and absorbs Gotenks and Piccolo into his being, deciding 30 minutes is more than enough to handle Gohan (he was right). Goku arrives and the fusion breaks down. Goku says Gohan alone is strong enough to defeat Buu, but then Buu reveals that he planned for this eventuality as well, and had a piece of himself ready to absorb Gohan the whole time, who he goaded into standing still until it was too late. Interestingly, the only character this didn't work on is Vegito, who was too strong, too wily, and had plans of his own, as he later found out...
  • You Wouldn't Like Me When I'm Angry!: Said almost verbatim to Vegito, notable in that it was after he absorbed Gohan, which at this point made him one of the two strongest characters in the series.
  • Your Magic's No Good Here: The fusion achieved by the Potara earrings is supposed to be permanent, but when Vegito is absorbed by Super Buu, immediately after lowering the shield he used to avoid being completely integrated into Buu (like Piccolo, Gohan and Gotenks were), there's something about Buu's innards that splits Vegito back into Goku and Vegeta. This is later revised in Dragon Ball Super, where it's revealed that Potara Fusion is only permanent for Kais. For mortals, it simply lasts an hour, and that hour just happened to be up to when he was absorbed.

    Ultra Buu
Voiced by (English): Brian Dobson (Ocean dub); Justin Cook (Funimation dub)

A form that Super Buu briefly showcases during his regression back to Kid Buu. It is technically his second form as Kid Buu takes this form after absorbing the South Supreme Kai, taking on a larger and bulkier look before absorbing the Grand Supreme Kai and becoming the Fat Buu that was first seen in the story.

  • Adapted Out: Because of his limited screen time, most video games don't mention his existence- how he was the midpoint that Kid Buu became Fat Buu, let alone make him playable. This makes his existence scarcer than Evil Buu who usually is mentioned as either The Ghost or a fighting role in The Tenkaichi games and Dragon Ball Heroes when most games ignore the latter's existence. Ultra Buu has only appeared in the latter.
  • Ambiguous Situation: When Super Buu regresses temporarily back to Ultra Buu Vegeta and Goku note his power drastically increased compared to the base Super Buu. It's not made explicitly clear where this form compares to either Buutenks or Buuhan in terms of power. It's rendered moot as he immediately regresses back to the weaker but more dangerous Kid Buu.
  • Ascended Extra: Downplayed. His existence is merely a few panels that serve as Super Buu's repression back to Kid Buu in the original manga. In the anime, he does get an appearance in the flashback, but that's to explain how Kid Buu became Fat Buu- visually fleshing out what was in the manga.
  • The Berserker: Much like the original Buu, but in a different manner than the unrestricted, chaotic child. From his flashback, he tended to charge at enemies at full force, bulldozing anyone in his way.
  • Black Eyes of Crazy: He retains the black sclera eyes of his previous Kid Buu form before losing them when he becomes Fat Buu- gaining the slanted white eyes with black pupils of the Grand Supreme Kai.
  • Clipped-Wing Angel: His instinctual decision to absorb the Grand Supreme Kai leads to him becoming the more passive Fat Buu due to the positive influence limiting his destructive nature rather than getting stronger and being more willing to be manipulated.
  • Dumb Muscle: While the other Buus have this aspect to varying degrees but but are surprisingly savvy when pushed to corner or hiding their overall intelligence, Ultra Buu from what was shown from his sole anime fight, is a straightforward fighter that bulldozed enemies and was immediately cut to pieces by Grand Supreme Kai when he blindingly rushes in for his trouble, with the absorption of the latter being instinctual to seemingly get more powerful.
  • Evil Is Bigger: From which little was shown of this form, his bulk gives the impression of being even larger than the regular Super Buu, who already towered over everyone.
  • Evil Sounds Deep: his screechy, impish voice from his original form becomes much lower and guttural after absorbing the South Supreme Kai, but once he absorbs the Grand Supreme Kai, he as Fat Buu gains a higher child-like voice.
  • Feral Villain: In a similar vein to Kid Buu, Ultra Buu was shown to be a rapid beast that rampaged whatever came in his path and showed no obvious signs of sapience.
  • Flat Character: Out of the forms of Buu and due to lack of screentime, he lacks any memorable characteristics- being a simple brute from what was shown of his fight with the Grand Supreme Kai.
  • Hulking Out: Compared to the muscular yet slender Super Buu, Ultra Buu is a top-heavy, bulky brute. In the anime, Super Buu's regression to this form is signified by him temporarily bulking his musculature to this form before becoming the smaller Kid Buu.
  • Minor Major Character: He only exists in the present in a few panels/minutes before regressing back to Kid Buu from Super Buu, but his absorption of the Grand Supreme Kai is the reason Fat Buu exists.
  • Nice Job Fixing It, Villain: His absorption of the Grand Supreme Kai leads him to become the more docile and weaker Fat Buu, leading him to be much easier to be manipulated by others and leading to him being sealed away for millions of years.
    • In the long term, this absorption led to the Grand Supreme Kai's influence ultimately dooming him as by proxy, Fat Buu limits Super Buu's potential actions due to his connection to Mr. Satan/Hercule and when he spits out Fat/Good Buu, the latter serves as a distraction that ultimately ends Buu as a whole, leading to Kid Buu being reincarnated as Uub.
  • Perpetual Frowner: During his entire screentime, he never smiles, being in a perpetual state of pure rage. Even the comparatively stoic Evil Buu gave two noticeable grins- one smug and memorably his crazed one as he becomes Super Buu.
    • Subverted in Heroes when in an anime promotion, Ultra Buu does smile in anticipation of fighting his enemy.
  • Small Role, Big Impact: Despite only appearing very briefly in both the present and past, his existence proves to be very significant. His absorption of Grand Supreme Kai leads to the creation of Fat Buu, who would later become a vital ally to the heroes once split from his evil. In the present, he is the signal that Buu is returning back to his original form.
  • Top-Heavy Guy: Compared to the more well-proportioned Super Buu, Ultra Buu's upper half is bulkier and larger than his stubbier lower half.
  • The Unfought: He is the only form of Buu that doesn't fight anyone in the present day, mainly due to being a random mutation in Buu's regression to his original form.
  • We Hardly Knew Ye: He has the shortest amount of screentime out of the forms of Buu, even compared to Evil Buu- having only additional screentime in an anime-only flashback to explain Fat Buu's existence and in the present, a sign that Fat Buu is regressing.

    Kid Buu 

Kid Buu (魔人ブウ 純粋, Majin Bū Junsui, "Pure Majin Boo")
Voiced by (English): Brian Dobson (Ocean dub); Josh Martin (Funimation dub); Kevin Seymour (DBGT: Final Bout)

"Me Buu, kill you!"

Buu's original form, and the form he takes again in the end. Kid Buu is the purest form of the character before he absorbed the Kais ages ago. Super Buu is forced back into this form after Fat Buu is separated from him again. Aside from the change in size and power, this also causes a significant decrease in intellect, to the point that this Buu is more an animal than a person. Kid Buu knows nothing but destructive rage and literally destroys the Earth just for fun (the Namek Dragon Balls put it back together again). He then rips a hole in reality to do the same to the Other World, but is confronted by Goku, Vegeta, and Fat Buu. The latter two manage to hold Kid Buu off while Goku gathers his biggest Spirit Bomb ever, which finally ends Kid Buu's reign of terror.

As Kid Buu dies, Goku pleads to him to come back as a good guy in his next life so they can have a fair fight. He does just that, and ten years later, Goku meets Kid Buu's reincarnation — Uub.

  • Adaptational Badass / Adaptational Wimp: An odd case of both.
    • In regards to the former, the anime version of the Buu arc inserts two lines stating that this Buu is actually the strongest version of Buu. But since the anime didn't bother to change anything else about the plot of the Buu arc, which stakes its whole plot on the idea that Goku is willing to fuse with Vegeta to fight Super Buu's various forms but not Kid Buu, this is purely an Informed Attribute.
    • In regards to the latter, the anime actually makes him look weaker with additional bits of Filler. These include Super Saiyan 2 Vegeta actually managing to land some good hits on Buu and make him angry with his refusal to stay down,note  Super Saiyan 3 Goku putting him on the ropes before stamina drain starts to take effect,note  and Fat Buu putting up a much more effective fight, plus getting up after his first beating to fight him again.note  Paradoxically, all these scenes actually make Buu look more clever - in the manga, he spends an extended period beating down Vegeta and Fat Buu long after they're able to fight back For the Evulz while ignoring Goku's Spirit Bomb (directly leading to his downfall), while in the anime he's actually seriously trying to attack Goku and has genuine trouble putting down Vegeta and Fat Buu.
  • Adaptational Intelligence: Gets a little bit of this in the anime when he finally notices the Spirit Bomb. As opposed to just attacking Goku instinctively, he quickly catches on that Goku is hesitating to throw the energy because Vegeta is in the way, and decides to use Vegeta as leverage to keep from detonating his final attack.
  • Adapted Out: Doesn't appear at all in the Supersonic Warriors games, Super Buu taking his place in scenes where he appeared in canon.
  • Almighty Idiot: He can't even speak outside of laughs and grunts. However, he fights in such a wild and unpredictable way and cares for nothing except killing that he is referred to as the most dangerous of all the Buu forms. Before he's killed, he destroys dozens of planets in minutes, and came very close to destroying the afterlife.
  • Ambiguous Innocence: While not in actions or deeds (he is an Eldritch Abomination that's destroyed worlds and slaughtered countless souls), this Buu can't be called malevolent or evil as that would imply he has the sapience, understanding, and moral agency to choose between "good" or "evil". Clearly, he does not. While it may seem like Buu is Made of Evil and he is clearly enjoying beating people and blowing up planets, he isn't engaging in active villainy like Frieza or Cell. Kid Buu is basically just a kid who likes kicking down sand castles but doesn't even notice the tears of the other kids that made them. He's not cruel for cruelty's sake nor does he exhibit the desire to do harm for his own benefit (which makes sense because he is The Needless). Hell, he's even able to push back against the Spirit Bomb and force it back towards a weakened Goku. Buu is pure at heart and while he seems like a demon, he's actually more like an amoral force of nature. Paradoxically, however...
  • Animal Motif: An ape, poetically enough for the Saiyan's final foe in Z. Appearing to have about the same level of sapience as a chimp or such, he even spends the start of his final fight just beating his chest and hooting.
  • Attention Deficit... Ooh, Shiny!: Kid Buu demonstrates an inability to focus on multiple enemies at once, immediately shifting his attention to whoever catches his attention no matter what point he was in the fight previously. This allows Vegeta, Fat Buu, and Hercule to all intervene multiple times to give Goku precious time and assure Buu's defeat.
  • Ax-Crazy: Unlike all other Dragon Ball villains, he can't be reasoned with or bargained with; all he cares about is destruction.
  • Big Bad: This incarnation of Buu takes the role in volume 42, with his reign lasting about half of that volume's page space. This makes him Buu's shortest-lived form, but he's still the final villain of the original manga and Z anime.
  • The Berserker: Kid Buu fights like a monstrous, wild animal and has no formal training, only pure strength, and savagery. He spares no one in combat and has no friends or foes so he can attack and kill whoever he wants.
  • Black Eyes of Crazy: His true form has black sclera and red irises, and is a completely murderous monstrosity.
  • Blood Knight: Despite only caring about destroying everything in sight, he takes his time and enjoys the fight with Goku, Vegeta, and Fat Buu.
  • Breather Boss: An odd In-Universe example. After doing everything in their power to immediately end Super Buu and avoid fighting him if at all possible, Goku and Vegeta become totally willing to screw around against Kid Buu and overall don't take him seriously. To be fair to them, he's a lot weaker than his previous incarnation, and while he did destroy the Earth this killed no one except four unconscious people still out cold from the struggle with Super Buu (the whole planet had already been depopulated by his previous two incarnations). That the heroes could've easily defeated him at any point using any one of a half dozen methods is repeatedly lampshaded, and considered highly frustrating by Elder Kai. Thankfully for Buu, Goku and Vegeta are more concerned with having fun fights and making moral points than anything else, so he lasts long enough to have a drawn-out final battle.
    • Vegeta crushes his Potara earring right before they fight Kid Buu. Kibito Kai is flabbergasted. Goku agrees with Vegeta and rejects Kibito Kai's extra pair of earrings, stating that unlike base Super Buu (who he had just been begging Vegeta to fuse with him against), it wouldn't be "fair" to fight Kid Buu with fusion, because "he ain't merged anymore either." Goku later notes that if they had used fusion, they could have destroyed Kid Buu with one small blast.
    • Goku and Vegeta refuse to team up against him, even though had they done so they probably could have won just by having Vegeta completely wipe out Buu's pieces before they can regenerate (it was stated previously that even someone as weak as Piccolo could have done so) after one of the many times Goku blew him apart. Old Kai calls them idiots for this, but they don't care. They say, again, that it wouldn't be fair, and instead choose to play rock-paper-scissors to see which of them will fight him alone. Goku goes first and, despite getting the upper hand at points, lacks the stamina to finish the job, so Buu always regenerates and eventually outlasts Goku's SS3.
    • After Goku fails and the Dragon Balls are gathered, he immediately suggests that they just bring Gohan to handle Buu. Vegeta rejects this, not because he doesn't think Gohan could do it, but because he doesn't think that the Z-warriors should save the Earth again, and thinks it would be better if Buu was defeated by the Earthlings' own energy. Hence, his Spirit Bomb plan.
    • After Kaio gets involved in the plan, he offers Vegeta the chance to talk with the entire universe. Vegeta refuses saying they shouldn't overdo it.
    • After Fat Buu gets expelled from Kid Buu's body and engages him, he shows himself to be decently close to Goku's strength and holds his own against Kid Buu for a while. Rather than having Kibito Kai or Dende restore their energy with his Healing Hands (it was shown that Kibito alone could do so even to people dozens of times stronger than he was, and Dende healed Gohan during his fight against Buutenks, and later healed Fat Buu after Kid Buu was dealt with) and ganging up on Kid Buu 3-1, which surely would have spelled victory given that Goku and Fat Buu individually would have killed him at certain points if they were more thorough in their follow-up attacks, Goku and Vegeta just watch the fight.
    • Similarly, despite suggesting it himself earlier against base Super Buu, Goku never tries to get Vegeta to do the Fusion Dance with him while Fat Buu is engaging in a long extended fight with Kid Buu. Instead, he agrees with Vegeta's point about responsibility and sticks with the Spirit Bomb.
    • In the end, Goku acknowledges Kid Buu as a Worthy Opponent and says it was really fun fighting him, even wishing for him to be reincarnated as a good guy. This is a far cry from the demeanors he held against Frieza, Cell, and Super Buu.
  • Clipped-Wing Angel: Zigzagged. Kid Buu is not as powerful as Super Buu (after absorbing Goten, Trunks, Piccolo, and Gohan), though to what extent is up for debate. However, he is still a legitimate threat and is indeed described as being the most dangerous of the Buu forms. This is because, whilst his raw power has decreased, he's also absolutely insane and so neither holds back at all nor has any drives beyond simply annihilating everything in sight. Fat Buu is just a dangerously powerful and uneducated child, Super Buu is a hotblooded and arrogant warrior, but Kid Buu is a near-mindless engine of destruction, leaving no outright weaknesses or flaws that can be exploited.
  • Confusion Fu: Kid Buu's primary "fighting style". He's completely unpredictable and uses his unique body to its fullest. This version of Buu is more like a wild beast than a trained fighter.
  • Darkest Hour: After so many close calls, he does what no other villain was able to do, destroy the Earth. Along with its destruction, the Dragon Balls are destroyed and Gohan, Goten, Trunks, Piccolo, and Tien are also killed. Things were dark before, but this is the series' low point.
  • Dirty Coward: Similarly to Piccolo Daimao, he tries to use an exhausted and immobilized Vegeta as a Human Shield to stop Goku from throwing the Spirit Bomb at him.
  • The Dreaded: Far more than his other forms: Shin was scared of the other forms for their power but knew they could be beaten with some effort and the right plan (and in fact was willing to actually fight Super Buu directly once he became Kibitoshin), but as soon as Buu started reverting to this form Kibitoshin fell to his knees in despair, as he knew he's just impossible to control or reason with.
  • Earth-Shattering Kaboom: He blows up the Earth with an energy ball known as Planet Burst that can do it ten times over.
  • Enfant Terrible: Well, he is billions of years old, but in appearance and personality, he's a spoiled, sociopathic child.
  • Establishing Character Moment: Upon his rebirth, he tries to destroy the Earth with an energy blast. When Vegeta stops it, he responds by making a giant ball of energy that's strong enough to destroy the Earth ten times over just so they can't stop it again. When Goku begs him to stop, he laughs before dropping the Planet Burst.
  • Evil Counterpart: His playful, ruthless nature parallels largely with Gotenks.
  • Feral Villain: Calling him a wild dog that likes to bite people and you're not far off. He barely talks in the manga and is far more interested In his own entertainment and the resultant mayhem then any sort of rational plan.
  • Fighting Clown: His behavior is all over the place, from falling asleep right as the fight is supposed to start to stalling his regeneration so he can dance around. Goku and Vegeta are not amused (Goku thinks he's doing the latter to taunt them).
  • Final Boss: This form of Buu is the true final villain of Dragon Ball Z, one of the most powerful villains ever and absolutely the most dangerous.
  • Flat Character: Played for Horror. Kid Buu is literally a mindless monster that only knows how to kill and destroy. His apparent lack of sentience and incredible power is what terrifies Super Buu the most.
  • For the Evulz: The only real explanation for most, if not all of his actions. He is described as being "evil incarnate". Unlike Super Buu, who at least cared about a good fight, Kid Buu just wants to destroy for the sake of destruction (his first act is to blow up Earth even after Vegeta challenged him to a fight).
  • Generic Doomsday Villain: He has no reason for blowing stuff up, he just does it and goes on to blow more stuff up. In this case Tropes Are Not Bad at all; Fat Buu was Obliviously Evil, Super Buu had an ego a smart individual could play to, but Kid Buu is completely unrestrained in his omnicidal drives, no bargaining or reasoning with him. It's not for nothing that everyone agrees this is what makes him the most dangerous, even if he lacks the raw power levels of his other forms.
  • Graceful Loser: Well, as graceful as you can be when you're insane. Unlike every major villain since Vegeta, he doesn't pitch a fit or Rage Quit when he's faced with death. Instead, he has an expression of silent resignation.
  • Horrifying the Horror: A tip of info, you'll know you're as Badass as Vegeta when you manage to intimidate an old as time god killing Eldritch Abomination by simply maintaining eye contact and glaring at it even if it's beaten you to a pulp. Only in the anime though.
  • The Hyena: The majority of Kid Buu's speech is composed of either maniacal laughter or insane screeches.
  • Insane Equals Violent: The most unhinged incarnation of Majin Buu, and of all Dragon Ball villains for that matter. Therefore, he's also the most destructive.
  • Killer Rabbit: Unlike his other forms, this version of Buu looks like a little kid, hence his English namesake. He is also by far the most dangerous form. Not only is he extremely powerful, but he doesn't have anything to restrain his power like the other Buu forms.
  • Knight of Cerebus: Upon his rebirth, he destroys the Earth (killing what's left of the main cast outside of Goku, Vegeta, Dende, and Mr. Satan) while laughing and then in the anime goes on to destroy at least five other planets in the span of a minute. Goku outright says that Buu will destroy the galaxy in less than an hour. To make things worse, he teleports into the Afterlife, ready to kill people who are already dead, which would effectively erase them from existence. His very existence brings the arc to its darkest point.
  • Lack of Empathy: He seems not to care about anything other than having fun, by fighting powerful people, killing, and causing lots and lots of destruction.
  • Laughably Evil: His goofy, unpredictable nature occasionally crosses the line into hilarious.
  • Laughing Mad: Bursts into random laughter during his fight with Goku.
  • Super-Scream: Several times he displays the ability to scream so loudly that planets quake from the sound waves. He seems to do this... well, just because.
  • Mood-Swinger: Goes from kill-happy to enraged at a drop of a hat.
  • Nightmare Face: Like Super Buu, he pulls several insane expressions and facial deformities that make him quite disturbing.
  • No-Holds-Barred Beatdown: He has Vegeta severely beaten in his last fight. He does the same thing as he beats the crap out of Fat Buu.
  • Non-Indicative Name: Chapter 49 of the Super manga reveals that the Kid Buu that Goku fought actually received the Grand Supreme Kai's divine power when Super Buu split, thus making this Kid Buu stronger than the original. In other words, he's not "Pure" Buu, contrary to his official Japanese name.
  • No-Nonsense Nemesis: Even more so than Super Buu. Kid Buu can't be reasoned with or bargained with. All he cares about is blowing stuff up. Goku and Vegeta have to lure him to the Supreme Kais' world to fight him because it's the only planet he can't one-shot.
  • Not-So-Harmless Villain: When first introduced, both Goku and Vegita perceive him as a joke, literally laugh at him and mock him for his size, each saying they can take him on. They can't. They're a lot less prone to consider him an easy challenge afterwards. However, when given the chance to fuse with the Potara they choose Honor Before Reason, and grow to regret it. By the end, when they do finally beat him, Vegeta even goes as far as to attempt to Shoot the Dog out of genuine fear.
  • Omnicidal Maniac: Again, the purest example. Kid Buu is less a villain than he is a rampaging force of nature - even Bibidi, his "creator", could do little but point him at people and watch the carnage.note 
  • Pint-Sized Powerhouse: One of the strongest beings in the universe and he looks like a ten year old.
  • Psycho for Hire: When he bothered paying attention to Bibidi's orders.
  • Pure Is Not Good: It is implied that Kid Buu is pure of heart in the final moments of his final battle as he manages to not only catch the Spirit Bomb (which almost vaporized him), but also almost pushes it back at Goku. Possibly overlapping with Children Are Innocent since by all appearances, he doesn't seem to possess the necessary intelligence to actually understand things like good and evil. He just loves the thrill of breaking things. In the original Japanese he is even called Pure Buu.
  • Rubber Man: Even more so than his previous forms. Using his amorphous nature is a big part of his Confusion Fu, stretching his punches, spreading out like a parachute to slow his momentum from being knocked back, and morphing to let attacks pass through him where possible rather than taking the hit and having to regenerate.
  • Sadist: A sadistic Omnicidal Maniac though not in the obvious way. His only purpose in life is to kill until there is nothing left as he enjoys the carnage and destruction. Interestingly, he doesn't seem to take much, if any pleasure in the pain of others as he never really takes his time killing his enemies or watches their pain inactively. Even when he beats Vegeta mercilessly, he isn't enjoying the pain so much as the act of pummeling Vegeta repeatedly. This could be due to the fact that Kid Buu cannot understand or comprehend emotion and is incapable of deep thought.
  • Smarter Than You Look: When Goku hesitates to throw the Spirit Bomb at him, he looks at Vegeta, beaten to the point of immobility, then smiles as he puts two and two together and pins Vegeta to the ground as he attacks Goku.
  • Story-Breaker Power: You thought Buu was broken before? Well he becomes worse after he learns the Supreme Kai's Instant Movement technique. He destroys a planet, regenerates, teleports to the next planet, and repeats several times, turning Buu into a galactic wrecking ball. On top of that, he uses his already confusing Confusion Fu to its fullest extent here to the point he can give an exhausted Super Saiyan 3 Gokunote  a tiring battle and easily dish out heavy beatings to Vegeta and Fat Buu.
  • Superior Successor: To Frieza and Cell, in regards to their attempts to destroy the Earth. Frieza technically doesn't go to that length during the Cell saga, but Cell does intend to blow up the Earth after losing to Gohan before Goku interferes, and his "Solar Kamehameha" would've done the trick had Gohan not stopped him. By contrast, when Kid Buu's first attempt to destroy the Earth is thwarted, he simply makes the next shot ten times bigger to ensure it won't miss, to the point that Kibito Kai has to take Goku, Vegeta, Dende, and Hercule away before the explosions consumes them, letting him do the one thing neither of his predecessors did and destroy the Earth.
  • Suddenly Voiced:
    • The English dub, and some Latin American dubs as well, give Kid Buu the ability to at least utter simple words, while in the manga and Japanese version Kid Buu can't speak at all. Following video games for the franchise rectify this to match the manga and render Kid Buu speechless.
    • He does speak once in the Japanese anime when SS3 Goku compliments his strength. His response? "Gonna kill you!". This scene isn't in the manga though.
  • Teleportation: Thanks to copying Kibito Kai's teleportation technique.
  • There Can Be Only One: He recognizes Fat Buu as being the compassionate type. Kid Buu don't play like that. Heck, he outright says it in the English dub, wherein they added a few lines.
    Me Buu. NOT YOU.
  • There Is No Kill Like Overkill: His very first act is to try to blow up the Earth. When Vegeta deflects the attack, he retaliates by making a Planet Burst so ridiculously overpowered that it would be impossible to stop; according to Goku, said energy ball is powerful enough to destroy the Earth ten times over.
  • This Is Gonna Suck: He has this reaction as Goku prepares to push the Spirit Bomb to kill him. This is noticeable since every other villain in Z either Rage Quits or screams in disbelief upon their defeat.
  • The Unfettered: There is plenty of debate on Kid Buu as to whether he is the most powerful incarnation, but everyone agrees that he is the most dangerous one. The other versions can be reasoned with to at least some extent; Kid Buu is virtually destruction incarnate.
  • Unskilled, but Strong: Played With. He's virtually a mindless machine of destruction, but he can sense energy and make the best use of his unusual body compared to all the other Buu forms (in fact, careful observations note that he has the fastest regeneration time out of all the Buu forms, being virtually instantaneous, probably because he's in his original form). At the same time, his attacks are wild and unpredictable, which actually makes him the most troublesome form of Buu to fight (especially since he's the most adept at exploiting his unique rubbery body.) There's also the matter that he can still instantly copy/recall the techniques he sees and pull them off without a hitch. It's also revealed in the Galactic Patrol Prisoner Arc he (and by extension Uub) actually got the Grand Supreme Kai and South Supreme Kai's gigantic amount of God Ki when Super Buu split ...but he seems to have no clue how to actually access it.
  • Unstoppable Rage: The other incarnations have this in one way or another, but Kid Buu is in this state the entire time.
  • Worthy Opponent: Despite being a nearly mindless creature of pure destruction, it's easy to tell that he views Goku and Vegeta as these given that he searches for them across several planets and takes his time fighting them. In the end, Goku returns the sentiment.
  • You No Take Candle: The few times he speaks in the English dub, he speaks like this ("Me Buu! Kill you!")

    Oob / Uub 

Oob / Uub (ウーブ, Uubu)
Voiced by (Japanese): Megumi Urawa (Kid Uub), Atsushi Kisaichi (Adult Uub)
Voiced by (English): Sean Michael Teague (Most media), Justin Briner (Xenoverse 2) (Funimation dub); Reece Thompson (Z), Brendan Hunter (Most of GT), Scott Roberts (GT ep. 1 only) (Ocean/Blue Water dub)
Voiced by (Latin American Spanish): Uraz Huerta (Kid Uub), Luis Daniel Ramírez (Adult Uub in GT and Kid Uub in Kai: The Final Chapters)

A young boy from a poor village who competes in the 28th World Martial Arts Tournament in order to win the prize money to buy food for the starving villagers. There, he fights against Goku, who offers to train him; Uub has enormous potential since he is actually the human reincarnation of Majin Buu. He completes his training at the beginning of the anime-only series GT, and returns to his village, but is called upon his duty to protect the Earth when he believes his mentor to have been killed in battle.

  • Barefoot Poverty: He's from a poor village and is always seen barefoot. The soles of his feet are shown to be quite filthy.
  • Beware the Nice Ones: He's a really nice guy, but push his buttons hard enough and he gets very powerful. Goku took advantage of it to get him to fight better in Z.
  • Big Damn Heroes: His unexpected early appearance in the Moro arc of Super has him transfer a massive sphere of godly energy to Goku, ensuring his victory against an Earth-merged Moro.
  • The Cameo: Combined with a Call-Forward, but Uub is mentioned quite a few times in Dragon Ball Super, but never directly appears. In chapter 31 of the manga, however, Goku actually sees him from atop Kami's lookout taking care of one of his brothers.
  • Chuck Cunningham Syndrome: Uub has no mention whatsoever in Dragon Ball Online.
  • Did You Just Punch Out Cthulhu?: While the fact that he is the reborn Kid Buu makes it kind of expected, since the last three episodes of Dragon Ball Z during which he debuted take place after the events of the Battle of Gods and Resurrection 'F' movies and the Super anime, Uub is the first human being to punch Goku after having become a Physical God and achieved Ultra Instinct in the face.
  • Double Meaning: Aside from the fact that Uub is Buu backward, his name also sounds like Ube, a purple yam that's common in Filipino desserts which given Buu's sweet tooth would not be surprising.
  • Good Counterpart: To Kid Buu, being his benevolent human reincarnation.
    • When he fuses with Fat Buu to become Majuub, he is this to Super Buu. He's even officially called Super Uub in the Japanese dub.
  • Half-Human Hybrid: Played With. He is a pure-blooded human, but he is also Kid Buu reincarnated. In GT, he merges with Fat Buu making him a type of hybrid.
  • Heel–Face Reincarnation: He is the reincarnation of Kid Buu, an unrepentant psychopath who blew up planets for fun. However, when Kid Buu gets reincarnated into Uub, he's much more benevolent.
  • Humanoid Abomination: While he's pure human, he's still the reincarnation of Majin Buu, and is leagues powerful enough to claim that.
  • I Gave My Word: He promised his parents that he would win the prize money at the 28th World Tournament and motivates himself to beat Goku by repeating his promise.
  • Last Episode, New Character: Much like Pan and Bulla, he is introduced during the last episodes of Z, specifically the second to last episode. Averted in GT, where the three of them appear more often.
  • Massive Numbered Siblings: Downplayed; it's stated he's the first of five children.
  • Master-Apprentice Chain: He is Goku's third student. Since Goku had a lot of masters, he has several chains, one which includes Whis.
    • Mutaito > Master Roshi > Son Gohan, Sr > Son Goku > Uub
    • Master Korin > Master Roshi > Son Goku > Uub
    • Kami and King Kai > Son Goku > Uub
    • Whis > Son Goku > Uub
  • More than Meets the Eye: Everybody except Goku underestimates him since he looks no more special than the other Cannon Fodder tournament contenders. The sight of this unassuming human boy trading punches with a godly-powered Saiyan quickly vindicates Goku.
  • Nice Guy: Unlike the evil Majin Buu, Uub is introduced as a polite young man who shows respect to anyone he fights. Anyone who isn't evil anyway.
  • Out of Focus: Along with Pan, Uub has been pushed out of focus entirely since the franchise has had a revival in the late 2000s. It's justified in the case of the anime and manga though since Battle of Gods, Resurrection F and Dragon Ball Super all take place before Uub is born and/or when he's still barely a few years old. On the other hand, his lack of inclusion in things like Dragon Ball Xenoverse is more baffling. He does play a vital role in killing Moro, as it's his god ki that is sent to Goku to finally destroy the sorcerer once and for all.
  • Performance Anxiety: He gets nervous about fighting in front of a crowd.
  • Physical God: The Super manga reveals that he inherited god ki from Kid Buu, who in turn retained it from absorbing the Grand Supreme Kai. The Grand Supreme Kai helps Uub utilize his latent potential to transfer a huge sphere of energy across the globe to Goku, which proves vital to defeating Moro.
  • Pint-Sized Powerhouse: He barely comes up to Goku's kneecaps, yet he can trade even blows with him.
  • Reincarnation: Of Majin Buu, more specifically Kid Buu. Hence, the name "Uub".
  • Revision: Chapter 43 of Dragon Ball Super establishes that Kid Buu inherited the god power of the Grand Supreme Kai, meaning that Uub is stronger than previously thought with godly potential in him. This doesn't contradict the original manga.
  • Sdrawkcab Alias: Uub is the reincarnation of Buu.
  • Spell My Name With An S: Uub/Ub/Ubb/Oob...
  • Suspiciously Similar Substitute: One of Piccolo (Junior) and Nam from the original Dragon Ball series. A reincarnation of a villain Goku defeated, he meets the latter in a World Tournament, and his introduction heralds a turning point/end of a series. He is also an Indian that needed the money for his village like Nam.
  • Token Minority: One of the few important dark-skinned characters in the series.
  • Unskilled, but Strong: His major issue was that he couldn't release his full strength, and even then, he hasn't got a handle on unique skills that required ki to use, like flight. Goku took it upon himself to help fix that. However, he is a quick learner - learning how to fight while having an intense fight with Goku. As for the strong part, he's the reincarnation of Kid Buu (this is also where his quick learner trait comes from). It's implied that even as a child, he has more god ki than all the Z-Fighters combined.
  • World's Strongest Man: In the original Z series and GT, he's by far the most powerful Earthling around. Of course, since he's the reincarnation of an immortal demon, it wouldn't be fair to compare him to Krillin or Tien. Dragon Ball Super Chapter 46 establishes that he inherited the Grand Supreme Kai god power too. The finale of the arc shows that even a young Uub possesses more god ki than all the Z-Fighters combined and is enough to turn the tables on Moro when given to Goku.

Tropes exclusive to Dragon Ball GT incarnation:
Click here to see Majuub

  • Adaptational Wimp: Majuub's Majin beam functions identically to Buu's own Candy Beam, but in games it doesn't transform anyone into chocolate.
  • Ambiguously Brown: After his fusion with Buu, the animators apparently can't decide if the boy is black, of some other dark-skinned ethnicity, or mixed-race.
  • Badass Boast: See Batman Gambit below for the details, but as soon as he reforms inside of Baby Vegeta's stomach, he lets out one hell of a good one.
    Uub: No one beats me with my own technique!
  • Batman Gambit: Pulled a beautiful one on Baby Vegeta. Originally it was believed that Baby had overpowered and reflected Uub's Chocolate Kamehameha back at him, transforming him into candy and eating him. Later it was revealed that Uub had planned the move to attack him from the inside, where he was at his weakest.
  • Big Damn Heroes: Despite his small role in GT, Uub made himself the protagonist of at least FOUR Big Damn Hero moments:
    • Firstly, he saved Pan from a Brainwashed and Crazy Gohan.
    • Secondly, he saved Goku, Gohan, Goten, Trunks, and Pan from Baby in the culmination of his Batman Gambit (see above);
    • Thirdly, he saved Gohan from General Rilldo (and destroyed the latter with a single blow);
    • And finally, he prevents Goku from being impaled by a statue (courtesy of Syn Shenron)... by destroying the statue with a blast.
  • Confusion Fu: Very downplayed compared to the Confusion Fu Buu's known for, but his attacks such as the Chocolate Kamehameha (essentially resulting in a beam that's faster and more powerful) and Lightning Arrow (which is a You Will Not Evade Me technique that transformed into a Combination Attack) show, Majuub can have some tricks up his sleeve.
  • Death of Personality: Majuub's creation causes Fat Buu's personality to fade away into Uub's subconscious.
  • Demoted to Extra: Surprisingly inconsequential in GT, despite Goku's intention to have him take his place as Earth's guardian.
  • Fusion Dance: In GT, he fuses with Fat Buu to become Majuub.
  • No-Sell: While he can have his own chocolate-inducing attack turned against him, Majuub can just as easily turn back to normal at any time.
  • Out of Focus: Quickly becomes irrelevant during the Black Star Dragon ball arc, gains some relevance in the Baby arc, and then loses relevance completely in the following two arcs.
  • Paper-Thin Disguise: His alter ego, Papayaman. This is the result of him having Performance Anxiety as shown in Z.
  • Power Up Let Down: Played With. While Majuub's creation does allow Uub to challenge and push back Super Baby 2, it's still not enough to grab him the win. Luckily, he comes up with a Batman Gambit to turn the tides later on. Played more straight forward in later arcs, where his power pales to the enemies around him, and cannot hope to beat Syn Shenron or Super 17.
  • Signature Move: Lighting Impact, which is Uub's answer to the Kamehameha, and Lightning Arrow, which is labeled as one of his most powerful techniques.
  • Split-Personality Merge: Sort of. He fuses with the Good Buu to become Super Uub (Majuub).
  • A Taste of Their Own Medicine: Baby is a Puppeteer Parasite who invades other people's bodies, laying eggs inside them to keep control of them and attacking them from the inside. Majuub tries to transform him using Majin Buu's Chocolate Beam, but Baby sends it back at him and devours him afterward. However, it later turns out that Majuub deliberately let himself be changed and swallowed so he could attack Baby from the inside, incapacitating him with pain during his fight with Goku; Majuub even tells Baby that he's doing what Baby himself does to everyone else.
    Majuub: Isn't that how you operate, Baby?! You lay your eggs in people and attack them from the inside!
  • Walking Shirtless Scene: In the first episode of GT, combined with Clothing Damage. After fusing with Buu, he wears a jacket that reveals his abs.
  • The Worf Effect: In Dragon Ball GT, against Super 17 and Syn Shenron. He's the reincarnation of Kid Buu, who killed four of the highest gods in the universe, fused with Fat Buu, who made Vegeta kill himself for nothing, and yet he still gets stomped by both of them.
