The primary antagonists of the series, a corrupt regime that wants to rid the world of hair.
The empire goes through four different iterations over the course of the franchise: the regular Chrome Dome Empire, which rules the world in the first series; the Former Chrome Empire, which ruled the world a cenutry prior to the beginning of the first series; the Shadow Chrome Dome Empire, which rules the underworld; and the Neo Chrome Dome Empire, which rules the world in Shinsetsu.
The Maruhage/Margarita Empire (The Chrome Dome Empire)
- Ambiguous Situation: Other than the Czar himself, most of the Block commanders, all the generic troops and the countless Cartoon Creatures, all the Hair Hunters sport full heads of hair, despite the fact they're tasked with ridding the world of hair. The fact nobody ever questions this, not even Bo-bobo himself or Only Sane Woman Beauty, just makes it stranger.
- Bald of Evil: Zigzagged. The majority of the grunts and the standard leaders, including the leader himself, possess no hair on their head. Initially subverted with H-Block, who have hair, but it turns out to be wigs....only for the Big 4, the right hand man of the Czar and prominent members to have ridiculous anime hair anyway.
- Beware the Silly Ones: It may be a regime chock-full of Cloudcuckoolanders that mean to cut everyone's hair off and use amusement parks for their military bases, but they still have near total control over the world.
- Early-Installment Weirdness: The justification for Hair Hunters who've still got hair being them just wearing wigs is more or less forgotten come the Pomade Ring arc.
- Hypocrite: The bulk of the soldiers of an empire that wants to rid the world of hair... have hair themselves. And sometimes to ridiculously Anime Hair extents. How exactly that works is anybody's guess.
- Leitmotif: Terrifying Margarita Empire, a Dark Reprise for Coming of the Hair Hunters. It's this for the Big Four, the Czar and his strongest aides.
- Stupid Evil: A good deal of the soldiers that make up this empire are as dumb as dirt. It makes you wonder how they were able to take over the world, they're so incompetent. And then there's their MO in general: they want to cut everyone's hair off, yet never take into consideration that, unless they outright destroy the folicles of their victims, the hair of every person they shave would just grow back.
- Ambiguously Human: Has Pointy Ears and sharp teeth, The Hollywood Cyborg reveal only makes it more complex.
- Authority Equals Asskicking: Subverted when push comes to shove, he's quick to run away when he's cornered.
- Bad Ass Normal: Heavily implied, you gotta respect a guy who's probably as strong as any other human for being able to command over several warriors much stronger than you.
- Justified: despite being part machine, he immediately rides away once his brother takes over.
- Bald of Evil: He's bald and he's a jerk.
- Batman Gambit: Hopes that the newly awakened Former Margarita Empire would defeat Bobobo for him, but it does not work at all. He later holds a tournament hoping that the enemies will kill each other off, but it forces him to vacate his throne when his Eviler than Thou brother takes over.
- Big Bad: till Hydrate forces him out of power.
- Big Bad Wannabe: he's merely a puppet figure for Bibibi of the first series.
- Facial Markings: On his forehead, he has a symbol.
- Godzilla Threshold: Several, reactivating the Wiggin' Block, relying on Giga, reawakening the previous generation of Hair Hunters and finally holding the Emperor Playoffs; the latter epically backfires on him.
- Hoist by His Own Petard: His own need to protect his throne is what led to the playoffs in which he loses his title to his brother.
- Hollywood Cyborg: Turns out to be one as demonstrated with partially cybernetic eye, but has none of the fighting power of the Third.
- Informed Ability: Soften makes Giga's power being equal to the 4th which is rendered mute when Hydrate forces him out of power
- Manipulative Bastard: He relies on coercing others to do his work for him and ultimately planned to have them kill each other in order to get the throne. It backfires when Hydrate takes the authority away from him.
- Nice Job Fixing It, Villain: He reliance on others to his work for him ultimately cost him his right to the throne, especially when the one who took the throne was the same little brother he sent away who trained to be by his side!
- Non-Action Big Bad: Despite being a Hollywood Cyborg, he displays no fighting abilities at all. The fact that he runs ungracefully from his throne once Hydrate takes over only establishes this point.
- Orcus on His Throne: It's no exaggeration that all of his elite forces plus the previous generation of Hair Hunters were defeated before he actually decided to take matters into his own hands, the method which decided to do so, backfires on him epically. It becomes justified once it's revealed that he was a Puppet King for Bibibi, having no fighting skills as a result.
- Pointy Ears: Has them along with sharp teeth.
- Puppet King: Bibibi's statement outright state this, which makes sense in hindsight that he didn't ever try to fight Bobobo on his own terms.
- The Reveal: Downplayed, he is actually a Hollywood Cyborg, but his immediate retreat from power reveals he's not that strong.
- Screw This, I'm Outta Here: Once Hydrate takes over, he ungracefully deserts his title to escape with his life.
- Smug Snake: His default fallback is that he calls someone of a high rank in the Empire to kill his enemies for him, and become angry when they lose. Considering he relied on Dengakuman as his first option didn't help his case. It ended up backfiring when his latest scheme to hold a tournament in hopes of finding someone to kill Bobobo for him, results in his dethronement by his very resentful brother, who managed to sneak in his entire kingdom into the tournament due to negligence and laziness of checking who killed Bobobo, only that it got it done.
- The Unfought: Despite being built up the Big Bad of the series for several arcs, he flees his empire once Hydrate takes over. And it turns out he was a Puppet King for Bibibi, to publicly run the Empie.
The Emperor's Aides
- The Dragon: In both literal as being a purple dragon and implied to be his right-hand mistress.
- Even Evil Has Loved Ones: She is the Czar's wife, one of the few people that he truly cares about, in spite of being a terrible boss regardless.
- Fluffy the Terrible: Would you expect a demonic-looking dinosaur thing be named "Mako-chan"?
- The Unfought: Like her spouse, she doesn't get to fight the Rebels once Hydrate took over.
- What, Exactly, Is Her Job?: She's effectively the czarina of the empire, yet never does anything in the series proper and, like Baldy Bald IV, flees when Hydrate appears.
- Team Pet: To the Czar, being a cute little sausage like octopus, but acts more like the royal announcer of events and advisor to the Emperor.
- The Dragon: Constantly seen with the emperor and gives the rules about a tournament to decide the next emperor.
- Anime Hair: Has purple hair of strands with clips at the end.
- As Super Giga, has two long pigtails.
- Arc Villain: Of Cyber City.
- Break the Haughty: Bobobo delivers a big one to him.
- Body Horror: He contorts the target of his art creation with two demonic shadows that squeeze the target till he/she is a clay doll
- Dimension Lord: As Super Giga, he can create dimension to No-Sell any attack that isn't art.
- The Dragon: To the 4th
- Dragon with an Agenda: If only to keep his authority.
- The Star Scream: And jumps at the opportunity to take away his former superior's authority at the Emperor's Playoffs
- Gratuitous French: His Objet D'Art is very French sounding, considering their association with art, it's done on purpose.
- Hate Sink: He's a sadistic man turning Fist users into warped clay sculptures by physically distorting them into such shapes with his powers, including Gasser at one point with fiendish glee. He runs Cyber City a prison facility for people, which consists of balding and tormenting people with unique public executions/tortures on live television for his own amusement. On top of this, he's an insufferable Smug Super with Smug Snake undertones, who is rude to everyone including his own boss that allows his activities to continue. Prominent examples being when he tells the heroes he wasn't using a Super Fist as a sign of mocking and later tries to destroy Gasser's statue out of spite. And unlike previous major villains, there is no Freudian Excuse implied or explicit, that implies he wasn't anything other than an unpleasant person from the start. And unlike OVER or Halekulani, he doesn't do Heel–Face Turn, fully intending to get revenge on Bobobo for his actions.
- Jerkass: He is extremely unpleasant with a clear disrespect to everyone, including his superior that's allowing his actions to continue. He enjoys messing with others for his own amusement like lying about using Super Fist techniques for the first half of the fight just to see their reactions.
- A Lady on Each Arm: Giga is usually accompanied by a pair of ladies, one named Biki who wears a bikini and another named Basro who wears a bathrobe.
- Living Doll Collector: Does this to Fist users.
- Mad Artist: His Fist, which allows for the creation of pieces of art that he uses to attack.
- One-Winged Angel: Turns into Super Giga, with grotesque armor and long pigtails.
- Smug Super: He has an insufferable ego, but it is backed up by powerful abilities that make him ranked high enough for him to be considered the right hand man of the Czar. To a point that he actually pretends that one attack was a Super Fist, only to reveal it wasn't, just to cement his superiority.
- Sonic Stunner: Giga Sound, which summons giant speakers to immobilize the enemy.
- Telepathy: Giga creates a formula chart to calculate the enemy's thoughts.
- Troll: He has a moment where he reveals to Bobobo and the others that he was only pretending to use his Super Fist in the first half of the fight, just for personal amusement.
- Villainous Breakdown: He starts off smug and arrogant, but gradually the continued resistance Bobobo and the others put on him, get him angry and by the time he's Super Giga, he's completely insane.
- The Worf Effect: The Dragon of the Czar himself ends up being effortlessly defeated by Crimson, one of the Shadow Chrome Dome Empire's Big Four, during the Bald Bowl. It happens again in Shinsetsu, where he's defeated by Hiragi and GURA.
The Strongest Hair Hunter
He's the master of the Dokuro Shinken (Super Fist of the Skull), which allows him to manipulate skulls and other such bones, and even reconstruct and reanimate skeletons to fight for him. Like OVER before him, he transforms into something outlandish in a last-ditch effort defeat Bo-bobo. In his case, it's Sambaman, a creature who loves to sing and dance, and is so strange that even Don Patch can't stand him.
- Always a Bigger Fish: Bar none the strongest Hair Hunter the empire's got, to the point where it's literally his title.
- Canon Foreigner: Originally appeared in the GBA game 9-Kyoku Senshi Gyagu Yūgō, where he was its True Final Boss.
- Climax Boss: He's the most powerful Hair Hunter from the fourth era of the Chrome Dome Empire the Rebels ever encounter. But once he's taken care of, the Shadow Chrome Dome Empire makes their move, and the Rebels direct their attention to them in favor of dethroning Baldy Bald IV.
- Defeat Means Friendship: Parodied. When he's defeated as Sambaman, he immediately chooses to defect from the empire and join the Rebels. Bo-bobo responds to this by strapping him to a rocket and launching him into space.
- Disc-One Final Boss: Of the first series in the sense of being the last Hair Hunter the Rebels ever fight and defeat, as Baldy Bald IV vanishes before he could be fought and Hydrate has nothing to do with the bigger picture. But once the Shadow Chrome Dome Empire's taken care of, Hatenko gives a letter to Bo-Bobo, revealing there's much more to the Hair Hunt than Bo-Bobo initially thought...
- Giant Space Flea from Nowhere: He's the most powerful Hair Hunter of all, but since his existence was never established prior to the Bald Bowl, he just... appears. It's exaggerated in the anime's English dub, where he's the only prominent Hair Hunter whose name and title go unrevealed.
- Killed Off for Real: Bo-bobo straps him to a rocket and shoots him into space. He's never seen or heard from again, not even in Shinsetsu, so he likely died from lack of oxygen after exiting the Earth's atmosphere.
- Meaningful Name: Named after the Yaksha from Hindu, Jain, and Buddhist folklore, spirits with dual personalities that guard the resources beneath the earth. It's supposed to reference how he's the empire's strongest solider and their last line of defense before the Bald Bowl's interrupted, and how he's a No-Nonsense Nemesis in his regular form, but a Cloudcuckoolander when he becomes Sambaman.
- No Name Given: The Yaksha has no name or title whatsoever in the English dub.
- No-Nonsense Nemesis: Takes himself very seriously, doesn't bother playing around to immediately go for the kill, and is a genuine force to be reckoned with. That is until he transforms into Sambaman...
- One-Winged Angel: Subverted. Bo-bobo and the gang make very quick work of him after he transforms into Sambaman.
- True Final Boss: Of 9-Kyoku Senshi Gyagu Yūgō.
- World's Strongest Man: The most powerful solider of the most powerful sovereign state in the world. That is, until the Rebels go to the Hair Kingdom and find out who the true mastermind behind the Hair Hunt is.
The Four Heavenly Kings (The Big Four)
A quartet of Hair Hunters who serve Baldy Bald IV as his highest generals.
- Authority Equals Asskicking: With the exception of Kittypoo, each of them are very strong in their own right, easily surpassing the skills of the Block leaders.
- Ax-Crazy: Each one of the Big Four is psychotically unstable in their own unique way. Gunkan/Captain Battleship is an incomprehensible Cloud Cuckoo Lander at times, Kitty-Poo is a Sadist with a Faux Affably Evil nature, OVER is unapologetically violent as well as bloodthirsty and Halekulani hides his insanity with a composed facade, but will go into Madness Mantra and Blank White Eyes when pushed to a corner.
- Big Bad Ensemble: While nominally top warriors that enforce the Emperor's will along with Giga, they act as individual villains of the own arcs with Battleship/Gunkan being The Starscream, Halekulani doing whatever he wants, OVER being around to be able to cut hair and kill others, and only Kittypoo's loyalties being ambiguous being defeated easily before he could get an arc to elaborate on his loyalties, which are all rendered mute when they all enter the Emperor's tournament to get back at Bobobo and potentially overthrow their former boss anyhow.
- Co-Dragons: With Giga
- Four Is Death: These four are the deadliest warriors in the current Empire outside of Giga and his Six Cyber Knights.
The first and weakest of the Big Four. Originally rival to Bo-bobo until he was not chosen to become the next heir to the Hair Kingdom due to simply not hailing from it. Through an unexplained series of events, he becomes a member of the Chrome Dome Empire's Big Four, and grew to have designs on overthrowing Baldy Bald IV. He kidnaps Beauty to force Bo-bobo to fight him; Bo-bobo wins and reveals all he really wanted was for Bo-bobo to acknowledge him. After that, however, he's flat out ignored for the rest of the story, only appearing to either be used for gags, or to get defeated by villains to establish how powerful they are.
He fights with the Garyū Hanage Shinken (Self-taught Super Fist of the Nose Hair), his own take on Bo-bobo's Hanage Shinken, which involves much more brutality and even his overtly long Pompadour.
- Affably Evil: He's the least evil of the Big 4, and he's an oddball like the rest of the main cast.
- A Father to His Men: He's much nicer to his minions than the other three, especially Kitty Poo and Halekulani.
- Benevolent Boss: Implied to have a more stable relationship with his minions than the rest of the four.
- Aloof Older Brother: We didn't even know he had a sibling working for the New Hair Kingdom until Goisu revealed himself.
- Arc Villain: Arguably the Disc-One Final Boss of the first half of the series ending the complete reliance on gags, and beginning its Genre Shift to more traditional Shōnen elements leading into the OVER arc.
- Beard of Evil: For some reason (other than being able to see his mouth more clearly), his beard is white while his pompadour is black.
- Beware the Silly Ones: Despite being almost completely nonsensical as Bobobo, he's just as badass.
- Bunny-Ears Lawyer: Despite being a wacko, he's just as effective a Nose hair user as Bobobo, if only he didn't try to use it for his own gain.
- Cloud Cuckoo Lander: Like Bobobo, and is the last major Big Bad with this intentional trait.
- Crouching Moron, Hidden Badass: He may be as big of a fool as Bobobo, but he's also one of the four leaders of the Hair Hunt Troop.
- Evil Counterpart: To Bo-bobo, in terms of his body structure, fighting with his nose hairs, being a total nutcase, having a supportive younger girl to aide him that's far saner than him, and having an outrageous hairstyle with strange things living inside it.
- Expy: Not as blatant as Bobobo's, but in terms of characterization and role is partially based on Shin with a little bit of Raoh throw-in, having the traits of being the rival who turned to the evil of the former while having the ambition and resentment of being passed over from the latter.
- Greater-Scope Villain: Of the arcs leading up to and during the C-Block and A-Block Arcs, with his agents acting on his behalf or he himself being subtly hinted throughout the early part of the series.
- Hard Work Hardly Works: Didn't earn the title as a master of the Fist of the Nose Hair because he doesn't have Royal Blood to the Hair Kingdom.
- Multiple-Choice Past: To go with his Bad Liar tendencies, he goes from saying he met Bobobo in a street brawl to being robots before finally admitting his Freudian Excuse of Hard Work Hardly Works.
- Nice Job Fixing It, Villain: Back when Bo-bobo and his friends were fighting against five of the Battleship Five Quartet, the gang won only one (two, if you were to count the battles against Calender and June 7th as separate battles) of the battles. Captain Battleship's team might have defeated Bo-bobo's team, if it weren't for the fact that after those battles, Captain Battleship accidentally pressed the Pomade Ring's self-destruct button while partying.
- Obfuscating Stupidity: When confronted with the fact he's one of the Big 4, he pretends to be an octopus so, therefore, he's not guilty of his crimes.
- Prehensile Hair: Like Bobobo, he can use nose-hair to attack his enemies. Even his ducktail at one point
- The Resenter: Despite being much harder working than Bo-bobo, he wasn't chosen to inherit the dojo because he wasn't descended from the Hair Kingdom. Or they were giant mechas and Bo-bobo got more prestige by having a better pilot. Either way, never forgave Bo-bobo for not giving him any credit.
- Rival Turned Evil: To Bobobo, through Hard Work Hardly Works Freudian Excuse reasons.
- The Star Scream: To the Margarita Empire, he even outright states it when he was interrogated. Subverted since he really wanted Bobobo to acknowledge him as a warrior.
The second member of the Big 4, a horned cat who rides in a pod that flies around in a pod with two elite henchmen, killing innocent lives if he gets annoyed by them and takes pleasure in it. Remind you of anyone? He finds Bobobo while terrorizing a village and proceeds to say how strong he is and how weak Gunkan was. Then, he gets beaten in one move by Don Patch of all people.
- Ax-Crazy: It's not as pronounced as the other members of the Big 4 due to his Faux Affably Evil nature, but he's a Sadist that likes to kill others with intense relish.
- Curb-Stomp Battle: Ends up being defeated the quickest of any of the Big Four (or any of the villains supposedly) when Don Patch does a Rapid-Fire Fisticuffs on him.
- Expy: Of Frieza. Both normally travel in flying pods, have one effeminate (although in Purupu's case, it's a woman) and one Gonk (in this case, a box of cigarettes/chocolates) henchmen accompanying them, are sadistic and are beaten easily by a character who later gains a Super Mode. His subordinates' names are meant to Parody the Edible Theme Naming of that series, as well. They're also both voiced by Ryūsei Nakao.
- Faux Affably Evil: Like the character he was inspired by, he's very formal and polite, hiding the fact that he's really an unapologetic Sadist.
- Hellish Pupils: His normally blue-green sparkly eyes become Yellow Eyes of Sneakiness when he shows his true nature.
- Informed Ability: He and his henchman were supposedly stronger than Gunkan but all three were curb-stomped by Don Patch of all people, their strengths are further supported by Hatenko, Don Patch, and Gasser's statements.
- Meaningful Name: Derived from "purupuru" the Japanese onomatopoeia for shivering, which makes the fact he's an Expy of another character with a name derived from something cold all the more blatant.
- Minor Major Character: Most of the named Mooks that had been faced before him took several chapters/episodes to defeat, and sometimes required the Rebels to either work together or fuse. Despite being a Heavenly King, Kitty-Poo gets effortlessly defeated by Don Patch of all characters, and is forgtten about for the remainder of the series.
- Small Name, Big Ego: If his swift defeat by Don Patch is an indication, then his claim of being Gunkan's superior is extremely exaggerated.
- Smug Snake: He talks a good game, but seriously lacks the power, his other teammates had. Doubles as overhyping himself.
- Villain of the Week: Ultimately this is what his and his two minions' role are, being the villains that are defeated in the same episode he's introduced in like early villains, specificially for the intermediary portion before the more significant Z-Block, Hajike/Wiggin', and Over's Castle Arcs- with the Evil Blood Mansion arc. This is especially jarring as Gunkan/Captain Battleship before him as well as OVER and Halekulani after him manage to be have entire arcs dedicated to defeating them in contrast.
- The Worf Effect: His easy defeat establishes Don Patch as being far more skilled than his initial status as a Gag Character implied.
- Yellow Eyes of Sneakiness: His normal aquamarine sparkle eyes become yellow irises with slits when he's ready for the kill.
The third member of the Big 4, he commands an army of Ninja and being the most dedicated to cutting hair, to the point where his weapon of choice is a giant pair of scissors. He punishes Battleship and Kitty-poo for failing to defeat Bo-bobo by cutting off their hair (well, in Kitty-poo's case, his antenna), then challenges Bo-bobo to a fight, with the latter eventually getting the better of him. That is, until he enters his true form: Torpedo Girl, an anthropomorphic torpedo woman... yes, really.
Torpedo Girl proceeds to beat the crap of Bo-bobo until he defeats the woman-weapons hybrid with an ultimate technique, causing Torpedo Girl to revert back to OVER. He then attempts a hostage situation with Suzu, only to be curb-stomped by Bo-bobo once again. He returns as Torpedo Girl to help the Rebels, until she becomes OVER again during their battle against the Baldy Bald III, only a short time later to remain as Torpedo Girl until the end of the series.
He wields the "Gokuaku Zanketsu Shinken" (Super Fist of the Ultimately Evil Sword), which amounts to him just hacking and slashing at his opponents with his scissors.
- Ambiguously Human: He has pointy ears, six orbs on his chest that light up when he's angered, and that's not even getting into the fact that his true form is an anthropomorphic torpedo.
- Ambiguous Situation: It turns out that Torpedo Girl's Landmine Dandy's daughter, but it's never explained how or why she reverted into OVER and joined the empire.
- Arc Villain: Of the "OVER's Castle" arc.
- Arch-Enemy: Jelly Jiggler is this to him, with his existence being enough to target him specifically. Nobody knows why, but it may have to due with the fact Jiggler defected from the empire to join the Rebels.
- Ax-Crazy: The craziest in the conventional sense in that he has an extreme Hair-Trigger Temper (no pun intended) and a morbid obsession with cutting hair, but not as crazy as BattleShip.
- Big Scissors: His weapon of choice, which is fitting since his primary job is to shave people bald.
- Blood Knight: He wants to fight Bobobo because he is strong and takes a liking to him after he's beaten by him.
- Berserk Button: His six orbs act as this whenever he gets annoyed, especially with Jelly Jiggler.
- The Brute: Among all of the Big 4, he is the first to resort to fighting rather than wait patiently like his cohorts to explain himself and all of his attacks are melee based In both forms.
- Catchphrase: Torpedo Girl's "I'm a Torpedo" to the point her Annoying Laugh is her own name. It's even lampshaded by Bobobo that it gets irritating very fast.
- Chekhov's Gunman: It's later revealed she was the daughter of the mentor to Hydrate, the Arc Villain of the Shadow Chrome Dome Empire during the current generation's foundation.
- The Comically Serious: His Ax-Crazy personality remains unflappable throughout all of his appearances even with all of the antics on display.
- Torpedo Girl parodies this as she strikes any signs of stupidity with extreme prejudice, but has shown to be Not So Above It All due to having her own eccentricities.
- Edible Theme Naming: All his Super Fist techniques are named after fruits. Word of God states he names them after fruits because he thinks the names of fruits are cool.
- Gender Bender: OVER's transformation turns him into a very female Torpedo Girl. Or rather, Torpedo Girl typically stays in the very male OVER form.
- Hair-Trigger Temper: When he gets annoyed, he gets extremely angry, and when all orbs light up, he...
- Multiple-Choice Past: As Torpedo Girl, she's introduced with the notion she was built as a standard model, but then a conflicting story with Hydrate states that she had a childhood with her father, Landmine Dandy being her father and neither explains how OVER himself came into the equation.
- Not-So-Harmless Villain: Gives the group the closest thing to a No-Holds-Barred Beatdown in the series just because she considers them Too Dumb to Live.
- Knight of Cerebus: He's played up as a legitimately serious villain with few quirks compared to the previous two Kings who were both quite goofy. Even his weapon, a giant pair of scissors, is comparatively tame in comparison to most fighting styles and also incredibly dangerous given the series' focus on hair. Then he transforms into Torpedo Girl, but ends up being a dangerous threat anyway due to being very effective against the goofiness of the heroes as she instantly attacks them whenever they act goofy.
- No-Nonsense Nemesis: OVER isn't into dragging out the fight when a person isn't worthy of fighting or indulging in the idiocies of the main cast, preferring to kill them at any opportunity when he was the Arc Villain.
- Parodied as Torpedo Girl. While she does attack the main cast for any sign of eccentric traits. She herself has weird character tics due to having a Wiggin' Specialist for a father.
- Not So Above It All: As Torpedo Girl, while she attempts to be a No-Nonsense Nemesis, she has eccentric tendencies like her I'm a Torpedo, her excessive crush on Soften amongst other things. Justified in that it's implied she she got it from her father, Landmine Dandy, a Wiggin' Specialist.
- One-Winged Angel: transforms into a female torpedo with lipstick, long fair legs with red heel-toed shoes, eyelashes, and a ridiculously feminine personality. Even the main characters are just disappointed by this.
- Only Sane Man: He's quite annoyed by Bobobo's actions, but he never has any of the outrageous outbursts that the rest of the straight men do. Despite becoming incredibly goofy himself when transformed into Torpedo Girl, her power actually comes from calling out others on their stupidity.
- Overly Long Name: The name of his Super Fist, from its Japanese name (Gokuaku Zanketsu Shinken), to its direct English translation (True Fist of Horrible, Bloody Murder), to its name in the anime's English dub (Super Fist of the Ultimately Evil Sword).
- Shear Menace: He wields a BFS version of these as a weapon to violently slash with horrifyinguly bloody results or or generate violet energy slashes at his enemies in the anime.
- Sixth Ranger: As Torpedo Girl, complete with a Heel–Face Turn.
- Smug Super: As Torpedo Girl, she's a very justified confidence that she is nigh-unstoppable and for the majority of the fight, there's little to prove her wrong.
- The Smurfette Principle: As Torpedo Girl, she's technically the only female of the Big 4, even though OVER is considered the official identity of the third seat. It's never revealed, however, if Baldy Bald IV, let alone the other members of the Big Four, know Torpedo Girl's his true form.
- Something Person: As Torpedo Girl.
- Token Evil Teammate:When he returns to being Over, he only helps Bobobo with the intention of killing him sooner or later after they get rid of Baldy Bald III.
- Unskilled, but Strong: His Super Fist amounts to little more than him swinging his scissors wildly at his opponent. That said, he's puts up quite the fight and all his attacks look very painful.
- Villainous Breakdown: As Torpedo Girl, she gradually stops her odd, feminine personality schtick and starts acting brutish and aggressive like OVER and then resorts to angry threats by the time she's defeated.
- Walking Spoiler: OVER having a true form called Torpedo Girl, who ends up being a very vital character in the backstory to the current foundation of the Chrome Dome Empire's current generation.
- White Hair, Black Heart: Has a long mane of white hair, which is very ironic considering the MO of the empire he works for.
- The Worf Effect: He hunts down Captain Battleship and Kitty-Poo after the Rebels are finished with them. As punishment for failing to defeat the Rebels, OVER beats them to a pulp and cuts off their hair (in Kitty-Poo's case, his antenna). The first time the Rebels lay eyes on OVER, he's licking his scissors while Battleship and Kitty-Poo are on the floor, unconscious and covered in blood.
- You Are What You Hate: In spite of being an Idiot Killer that attacks anyone showing intense idiocy or being otherwise Too Dumb to Live; Torpedo Girl has displayed her own eccentricities at times due to having a Wiggin' Specialist for a father.
- You Have Failed Me: Punishes Kitty Poo and Battleship for losing to Bobobo.
The final and strongest of the Big Four, a narcissistic millionaire and the creator and owner of Hallelujah Land, yet another Amusement Park of Doom. He left the empire for reasons unknown, only to conveniently come back as soon as the other three were defeated. He waits for Bobobo to come after him, only to get beaten a little more easily than Over. He eventually helps Bobobo against the Shadow Chrome Dome Empire, never to appear again afterwards until the end of the series.
He wields the Super Fist of Gorgeousness, which allows him to manipulate money and precious stones.
- Anime Hair: Spiky Shonen Hair of green.
- Anti-Hero: After his Heel–Face Turn, he decides to fight the Reverse Empire with the Rebels but is mostly motivated by anger at nearly being used. During the fight against Crimson, after suffering repeated attacks from both sides, he regains his Blank White Eyes and starts throwing money at everyone, though this does aide in defeating Crimson by allowing the creation of Kintenbo.
- Arc Villain: Of the "Hallelujah Land" arc.
- Armor Is Useless: During the course of their fight, his armor has done nothing to protect him from Bobobo's attacks.
- Zigzagged in the fight against Crimson. After regaining his Blank White Eyes, he transforms his armor into a large amount of money that attacks everyone with. While it is useless as armor, it makes a powerful weapon.
- Ax-Crazy: He usually hides it with a calm and composed nature, but when pushed to a corner, he reveals to be a money obsessed lunatic complete with Blank White Eyes.
- Big Ol' Eyebrows: Green ones.
- Blank White Eyes: During his Villainous Breakdown, and it's creepy.
- Curb-Stomp Battle: Ultimately, what his nearly one-sided fight with Bobobo amounted to. Not helped by the fact he gets hit twice immediately into the fight.
- Expy: Of Broly, even the fact he turns white eyed when driven mad.
- Final Boss: Of some of the videogames due to them being released when his arc was still going on.
- Freudian Excuse: Implied to have one, but Bobobo immediately hits him before he get even started.
- Though supplementary materials it's revealed later on he had to live a hard life due to being poor and needing to steal to survive. And it is implied through this that his extreme obsession with money was so he wouldn't be poor again.
- Gemstone Assault: One of the many applications of his Fist of Gorgeousness.
- Greed: His motivation for anything
- Kick the Dog: He blows up attractions whenever they don't make a profit, even with people inside!
- Madness Mantra: From the manga, to the anime, to the games, he will inevitably go insane and undergo a Villainous Breakdown where he says "money" over and over.
- Noodle Incident: Whatever made him left the Empire in the first place.
- Pet the Dog: He saves Beauty from Blonde Chainey during the Bald Bowl, only to tell her to let Bobobo know he's coming for him.
- Heel–Face Turn: What saving Beauty from Blonde Chainey leads to.
- Money Mauling: His Fist of Gorgeousness revolves around this.
- Put on a Bus: He simply returns to Hallelujah land after Hydrate is dispatched, serving no role in the remainder of the original series or Shinsetsu. He does receive a cameo at Jelly Jiggler's Margarita reunion party at the end though.
- Screw the Rules, I Have Money!: His Fist of Gorgeousness revolves around this, and the fact that he's rich also. In fact, all he cares about is money, in fact he begins a Madness Mantra about money.
- Super Mode: He essentially becomes Broly when he enters his ultimate form. It didn't really help against Bobobo at all, though.
- Taken for Granite: His "Death Money Board Game" slowly turns people into diamonds as he drains their spirit money.
- Talk to the Fist: He's interrupted during his explanation of his Super Fist
- Tragic Villain: It's implied that he has a sad backstory, and he would have told it...if Bobobo had not attacked him before he could get more than one sentence out.
- Bonus manga material reveals he used to live as a street rat, having to steal to survive. His past led to his developing his obsession with money and his Fist of Gorgousness.
- Villainous Breakdown: Not even OVER can hold a candle to how insane Halekulani becomes during the climax of his arc.
- You Have Failed Me: Has a Mook turn into a coin for this.
Block Commanders
- Minor Major Character: He's the head commander of the Block leaders and is supposedly stronger than Jiggler, but never appears after the first chapter/episode.
- Momma's Boy: He still lives with his mother, much to his lower officers' surprise.
- Only Known By His Nickname: His real name, according to his mother, is "Tsutomu". He hates being called that.
- The Un Fought: Bo-bobo never fights or meets him, as he goes straight for the Big 4 after taking down Jiggler.
- The Unfought: He never fights Bobobo directly, having been taken out offscreen by Suzu.
The commander of C-Block, who resides on the top floor of C-Block's Aitsuhage Tower.
- Arc Villain: Of the C-Block Arc.
- Blow You Away: His fighting style.
- Early-Bird Cameo: Shows up at the meeting with the other top Hair Hunt Troop commanders before taking a bigger role as the Arc Villain of the C-Block Arc.
- Killed Off for Real: Wall Man swallows him up. Notable because he's one of the very few villains to outright die.
- The Worf Effect: Twice, he loses easily to Gasser in his introductory fight, and is then easily assimilated by Wall-Man.
- Bunny-Ears Lawyer: Quite literally as he wears pink bunny pajamas while also being a top Hair Hunt Troop commander.
- The Unfought: He never fights Bobobo or his allies due to Bobobo never personally showing up to defeat him.
- Malevolent Masked Man: Have blue, menacing hoods over their faces.
- The Unfought: Neither of them fight Bobobo.
- Sissy Villain: He has very effeminate mannerisms.
- Starter Villain: The first major villain Bobobo defeats.
- Blessed with Suck: Averted. Unlike his third cousin, he's got the ability to turn his petrificaiton powers on and off.
- Butt-Monkey: In addition to being defeated by Bobobo easily, the latter completely screws up his date by making him look bad.
- Early-Installment Weirdness: He and the troops he commands are some of Bo-bobo's earliest opponents, and they've got the distinction of being the only Hair Hunter group with a sensible justification for why they've still got hair: they're all wearing wigs.
- Taken for Granite: Like Medusa, he possesses the power to turn people into stone, but Bobobo turns into various vegetables instead for some odd reason.
- Beard of Evil: Has a sinister goatee and mustache.
- Taken for Granite: Essentially what Hatenko did to him, and he's often portrayed in this state whenever he's shown or mentioned.
- We Hardly Knew Ye: The only mention he receives is that of being an enemy that Hatenko defeated in a flashback.
- Brought to You by the Letter "S": He's got an M-shaped opening in the middle of his bangs.
- Gonk: Has a curved oval shaped head with no nose and a perpetual duckface expression.
- Non-Standard Character Design: He has a much more simpler and laidback design compared to the more wild and frenzied designs of the cast.
- The Worf Effect: Didn't stand a chance against Hatenko.
- Bald of Evil: A noticeable aversion, he's the only known Hair Hunter Commander of the 4th's generation to legitimately have hair.
- Broken Record: Every time he appears onscreen, he panics and exclaims "You gotta believe me! I'm not an appetizer! I was looking for my contact lens and I got stuck in the rice! Don't eat me!
- The Worf Effect: He's already defeated by Rice by the time he appears on screen.
- A Mind Is a Terrible Thing to Read: When trying to read Bobobo's mind, he sees a skit in which a bunch of Bobobos in a market research meeting planning to sell nose hair rings. When one of them remarks that they'll make a movie about the nose hair rings, Kodebun exclaims that it'll bomb and promptly tries to wake Bobobo out of his stupor.
- Paper-Thin Disguise: So thin there wasn't even a disguise at all. Bobobo fishes him up from the river, believing him to be a mackerel, and only Beauty points out that he's a Hair Hunter.Kodebun: How did you see through my disguise and know that I was a Hair Hunt Trooper?Beauty: Years of training.
- Telepathy: His main power is being able to read minds.
- Adaptation Distillation: Robot Block is made to be a part of Z-Block in the anime.
- Fusion Dance: They're able to become a Masked Luchador like being called I'm Sorry Masked Man, which Bobobo and Don Patch also become during their fight.
G-Block
- Curb-Stomp Battle: Bo-bobo defeats him with one attack, and it wasn't even a named attack.
H-Block
- Sadist: It's heavily implied in addition to wanting to sell it on the black market that he does it for his own sick amusement.
L-Block
- Shout-Out: He looks very much like a LEGO mini-figure.
- The Worf Effect: He manages to easily defeat Gasser but loses easily to Bo-bobo, who demonstrates his alternative Fist to defeat him. It's meant to show Gasser's inexperience and overreliance on his Super Fist, and Bo-bobo's greater experience and versatility in combat.
- Weak, but Skilled: He doesn't have a Super Fist and can only flail his arms to attack. That said, he never lets up on it and is surprisingly quick on his feet, to the point where Gasser never gets a single hit in before Bo-bobo intervenes.
C-Block
- Adaptational Badass: In the manga, he's easily taken out by Don Patch using his "Don Patch Hammer" on him, i.e. another green onion, with Bo-bobo showing up after his defeat to pick up Beauty and Don Patch. The anime makes him slightly more of a threat by shrugging off the green onion and Bo-bobo's arrival having him join the fight, resulting in him having a full on fight with Bo-bobo and Don Patch, requiring he be defeated by the Fist of the Nose Hair.
- Ambiguously Human: Has much pinker skin as well as longer ears than a human, but is never directly confirmed to be non-human.
- Expy: Of Piccolo. He even fires his Hairloss Beam the same way Piccolo fires his Special Beam Cannon.
- No Ontological Inertia: Subverted. Bo-bobo defeating him doesn't reverse the effects of his Hairloss Beam, so Beauty (and Don Patch) are still doomed to lose their hair within 10 hours. Thus, they've no choice but to go to C-Block and get Geha to reverse the effects for them.
Tesuikatsu
The guardian of the Aitsuhage Tower's Red Hot Room.- Brought to You by the Letter "S": Has a blue "1" emblazoned on his forehead, to signify he's the tower's first guardian.
- Honor Before Reason: When Bo-bobo decides to use the elevator, he implores Bobobo to use the stairs instead for this reason.
- Killed Off for Real: In the manga, where Don Patch throws a grenade in the elevator, blowing Tesuikatsu to bits. In the anime, he's just blown against a wall, knocking him unconscious.
Shop Manager
The guardian of the Aitsuhage Tower's Thunder Room (a.k.a. a video store, hence his title).- Bad Boss: He apparently detests Keseran Pasera, a paramecia that works for him, and tries to fire them for little to no reason. This is more than enough for him to earn Bobobo's wrath.
Usa-chan the Rabbit (Vicious Velvet the Rabbit)
The "guardian" of the Aitsuhage Tower's Rapids Room (a.k.a. a video store identical to the one in the Thunder Room).- Adapted Out: Of the original broadcast dub.
- Harmless Villain: Due to being a powerless toy rabbit that does nothing but trash-talk. Beauty ties it ears into a knot, making it the only opponent Beauty "defeats".
- Riddle for the Ages: Arguably the biggest one in the franchise. One can only imagine how (let alone why) a stuffed animal can work for an evil empire.
A-Block
- Affably Evil: Engages in polite chat with Bobobo in the Ferris wheel while they are riding it.
- Large Ham: Makes loud announcements on the ride.
- Ambiguously Gay: There's really no other reason why he'd be interested in "Patchimi", considering "she's" just Don Patch, who's clearly male, pretending to be female. Though it can be argued he fell for Don Patch's guise and just thought he was a girl (and still thinks he is, even without his makeup).
- Face–Heel Turn: He went from a nice U to a manipulative 6.
- You Are Number 6: Literally transformed from a U to a 6 when he became a Hair Hunter.
- Informed Species: They don't really look like any pirahnas you might be used to seeing.
- Mooks: Serves as Katsu's minions, but they're not particularly powerful or a threat.
- Noodle Incident: His battle with the rebels. We just see him defeated but we don't see the battle itself.
- Neutral Female: For the most part, as she doesn't get into any fights with the heroes, though she does make Don Patch stay behind to finish his homework (that she gave him).
- Samus Is a Girl: Initially assumed to be male due to her initial male sounding voice until the mask comes off.
- Ambiguous Gender: The English dub implies their female but it's not said or shown either way.
- Token Good Teammate: As one of the major parts of the park, she just does her job with nothing else in mind, let alone any attempt on the heroes.
- Defector from Decadence: Implied to be a former Hair Hunter and a member of A-Block and decided to turn on his masters some time in the past.
- Remember the New Guy?: Played for Laughs naturally. Bobobo and Don Patch seem to know him, but Beauty sure as hell doesn't.
The deputy commander of A-Block, who likes taking his opponents' possessions after defeating them as "trophies". Though he doesn't have a Super Fist, he makes up for it with his "Playback-Vac", sentient faces that appear on his body and absorb any attack coming at him.
- Almighty Janitor: Despite only being A-Block's deputy commander, he's incredibly powerful, nearly killing Gasser and being a match to Bo-bobo when they fought. He was only beaten when an unrestrained Gasser managed to overload him. During the Bald Bowl, he was worthy of holding a gold medal and fought alongside the Dark Yaksha a.k.a. the Hair Hunters' commander-in-chief. To put it in perspective, Giga, The Dragon of Tsuru Tsurulina IV himself, only had a silver medal. But in the end, he still couldn't defeat Jelly Jiggler, his former boss, and loses to him after getting hit with one attack.
- Bald of Evil: One of the very few Hair Hunters that's bald and is genuinely evil.
- Curb-Stomp Battle : From his former superior, Jelly Jiggler, during the Bald Bowl.
- Hoist by His Own Petard: Katsu has a large admiration for accessories, leading to him removing Gasser's collar. With the collar removed, Gasser enters his baby mentality, multiplying his power ten fold. The increased amount of gas proves too much for the Playback-Vac, leading to his defeat.
- No-Nonsense Nemesis: Besides the weird way his power manifests on his body, Katsu's one of the very few Hair Hunters that doesn't mess around. He's a bloodthirsty solider of an evil empire through and through, and if he hadn't taken Gasser's collar off, the Rebels' journey likely would've ended right there.
- No-Sell: His Playback-Vac is this to any one who wields a Super Fist. It can absorb any and all Super Fist techniques by having smiley faces appear all over his body. Whatever they eat is called "delicious". Even Gasser's farts! It does have a limit though....
- The Dragon: The deputy commander of A-Block, which Jiggler commanded before defecting from the empire to join the Rebels.
- The Star Scream: Has no problem trying to kill Jiggler in the Bald Bowl.
The Pomade Ring
- A Dog Named "Dog": Aside from Loincloth Lloyd and Death Mask, all of the other members names are like this. The rest of the group consists of Calendar, his son June 7th, Tough-Looking Guy, and Gum.
- Animate Inanimate Object: Calendar is a talking calendar, and June 7th is a talking page from inside Calendar. Gum, though, is only animate when the group is wearing their cloaks and masks, and is otherwise just an inanimate stick of yogurt flavored gum.
- Black Cloak: When they first show up, they all appear as humanoids wearing black cloaks with white masks. This is despite the fact that Calendar and June 7th aren't at all humanoid in shape, Tough-Looking Guy is much larger outside of his disguise, and Gum is a stick of gum.
- Informed Ability: The English dub implies them to be famous singers, as hinted by their name. However, they're never actually shown singing.
- Non-Indicative Name: There are actually six members of the group, although June 7th claims that his father, Calendar, wasn't a real member. The English dub name for them makes even less sense, since a quartet consists of four people.
- The final member, Death Mask, has an adorable looking kitten face.
Fundoshitarō (Loincloth Lloyd)
A former ally of Gasser in protecting Gasser's hometown, only to join Battleship's Five Quartet for unknown reasons.- Affably Evil: When Gasser finds out he's set to fight his former ally, Loincloth Lloyd reveals his new allegiance to the Battleship Five Quartet as if it was just a casual conversation.
- Evil Former Friend: He was Gasser's friend who he fought alongside while defending their home city before joining The Battleship Five Quartet.
- Expy: A very obvious homage to Kinnikuman from his appearance and some of his behavior.
- Pyrrhic Victory: Wins against Gasser, but is so surprised at his victory his loincloth falls off. Completely humiliated, he vanished for the rest of the series and didn't appear until a new one rolled around.
Calendar
Bobobo's opponent.- Does This Remind You of Anything?: Bobobo trying to lift up Calendar's pages is treated like he's trying to lift up a girl's skirt, complete with Bobobo making some lecherous faces. Meanwhile, Calendar reacts to being exposed like he's been Defiled Forever.
- Killed Off for Real: Was killed after losing all of his calendar pages.
- Spared by the Adaptation: While he dies in the original, the dub instead changes him to just falling unconscious, with June 7th stating he's going to hibernate for the next year.
June 7th
The son of Calendar.- Expy: Has a very Arnold Schwarzenegger-esque voice in the dub.
- Not-So-Harmless Villain: Manages to dodge Bobobo's Nose Hair, forcing him to use Bobobo World in order to confuse him into insanity.
Tough-looking Guy
Don Patch's opponent.- The Brute: Easily the largest and toughest-looking of the Battleship Five Quartet.
- Curb-Stomp Battle: Delivers an (off-screen) massive one to Don Patch.
- Invincible Villain: Effortlessly decimates Don Patch and, though he never appears again after the Pomade Ring arc, is one of the very few Hair Hunters one of the Rebels fight but never defeat.
- No-Nonsense Nemesis: Heavily implied. He doesn't bother toying with his enemy nor indulge in Don Patch's antics. He immediately beats Don Patch the moment the latter challenges him.
- Perpetual Frowner: His entire screen time outside of his mask has him in a constant scowl.
- The Stoic: Outside of his quirky clothed disguise, he acts reserved and serious.
- Shout-Out: Looks like he was ripped straight out of Fist of the North Star.
Gum
A piece of gum that manages to be Jelly Jiggler's opponent. Not a sentient one, but a literal, lifeless piece of gum.- Companion Cube: Gum somehow goes from being a humanoid in a cloak to being a completely inanimate stick of gum.
- Curb-Stomp Battle: Manages to do this psychologically to Jelly Jiggler by being the food that was more preferable to a dog.
- Dark Horse Victory: Jelly Jiggler can't even win a battle against an inanimate stick of gum.
- Inanimate Competitor: Although it was somehow animate when wearing his Battleship Five Quartet costume, once Jelly Jiggler is sent in to fight, it's just nothing but a stick of gum lying on the ground.
Death Mask
The last of the Battleship Five Quartet.- Cats Are Mean: Invoked with his cutesy cat mask.
- Forced Transformation: Causes Beauty to become a doll.
- Small Role, Big Impact: He's quickly introduced just to turn Beauty into a doll, and Gasser crushes him in his hand shortly after. He's not onscreen for very long, but his meddling results in Beauty being captured for several episodes
- Heart Is an Awesome Power: His powers to make those hit by his eye beam into rice-soup obsessed loons might seem like a worthless power at first, but it's actually an effective tactic to make his enemies less willing to fight.
- Octopoid Aliens: Resembles a green triple eye-socket version of one with a dopey looking face.
- Unusually Uninteresting Sight: Aside from a gag played for laughs, no one is that shocked about an alien that's facing the heroes, other than being an enemy- except Beauty. Given the much weirder elements there are in the series, he's relatively normal by comparison.
- The Assimilator: His power is being able to assimilate others into his body and then utilize their Fist Technique.
- Our Monsters Are Weird: He's a white, golden tusked, frill eared, long armed and big bodied creature with a relatively humanoid face.
- You Will Be Assimilated: Does this to Geha and planned to do this to Gasser.
The Evil Blood Mansion (The Evil House of Blood)
- Cartoon Creature: Best described as a reptilian rodent of some sort, but it's less as extreme as cases like Don Patch.
- Evil Genius: Describes himself as the evil scientist in charge of the major developments of the Empire.
- Smug Snake: He's very sure of himself in spite of not being aware of the type of series he's in, and is one of the few traditionally played villains in the show- an egotistical scientist.
- Wrong Genre Savvy: Thinks he's in your typical Shōnen scenario where he's the overconfident yet cunning genius that has the hero in his clutches...up until Bobobo decides to remind him the wacky, irrelevance of the show.
Z-Block
- Adapted Out: Doesn't appear in the anime.
- Angry Guard Dog: In spite of his cutesy appearance, he's a bit ill-tempered than foaming angry like most dogs.
- Bald of Evil: As a standard Hair Hunt Trooper, it's a given. He's a manipulative man who distracts Bobobo so he can attack his friends in the midst of the distraction.
- Evil All Along: He initially seems to be an innocuous game show host before revealing himself to be a manipulative Hair Hunter that wanted Bobobo out of the way so he could take out the weaker members of the group.
- Killed Off for Real: When Bobobo from an Alternate Universe Kinda Like His Alter Ego turns into a dragon while still instead of Radio Man, the latter is expectedly killed when the former bursts out of him, making him one of the few confirmed permanent deaths on the enemies' side.
- No Indoor Voice: He never stops shouting.Radio Man: I'M LOUD!
- Non-Indicative Name: Radio Man is a giant television and not a radio.
- Harmless Villain: All of them are very weak in spite of their initially intimidating appearance, pathetically unable to pull in most of the group and only by bribing Don Patch that they manage to get him in.
- Bald of Evil: As a standard Hair Hunter, it's a given. He traps Bobobo and Don Patch in Radio Man, intent on keeping them in for the rest of their lives.
- Blinded by the Light: His main form of attack is utilizing a spotlight rig he wears on his body.
- Meaningful Name: His name makes illumination, which he does by utilizing his lights to blind his enemies.
- Art Shift: When Bobobo's alternate self turns into a dragon, one of the chef's faces goes more realistic as he stares in awe of the dragon's might.
- Nonstandard Character Design: In their true forms, they look like cartoonish caricatures of chefs with small beady eyes widely spaced from each other, bulbous noses and no visible mouths.
- Not-So-Harmless Villain: Double-Subverted. First they're actually the strongest base soldiers of the Chrome Dome Empire...., but reveal themselves to be very cartoony looking chefs whose only power is overcrowding their enemies...which actually proves to be a very useful tactic that nearly suffocates both Gasser and Beauty until Bobobo turns into a dragon to scatter them.
- Alliterative Name: In the dub, he's named Zeb Ziegler, likely to play on the Z-Block name theme.
- The Dragon: Officially, he's this to Dengakuman as the Vice Leader of Z-Block, being the last enemy faced before Dengakuman himself shows up.
- Co-Dragons: He shares this with Silhouette and Hibi, being the official second in command while the latter two are always aiding him. Justified as he had been eaten and it's implied that they occupied the empty slot during the five years that Bobobo had eaten him.
- Determinator: He was apparently eaten alive by Bobobo 5 years ago and managed to not get digested or die until he managed to escape and enact his vengeance on Bobobo.
- Eaten Alive: Apparently, Bobobo ate him alive 5 years ago and only 5 years later when he was hatched from an egg laid by Bobobo's alternate self's dragon form that he manages to escape.
- Noodle Incident: Apparently, Kibahage faced Bobobo five years ago, somehow was eaten by the latter, and later hatched as an egg when Bobobo turned into a dragon that had been Bobobo's alternative self-managing to survive not being digested while in his stomach. Notably, it's this moment that proves too weird for Beauty, who had seen very weird things up to this point to go temporarily insane and goofy like the cast due to how weird even in context this series of events was.
- Face Framed in Shadow: Exaggerated with Silhouette, as his entire body is constantly in shadow, even after he exposes himself to the Rebels.
- False Friend: In spite of showering Dengakuman with praise for most of their appearance, they turn on him when he's cornered by Bo-bobo.
- Sinister Silhouettes: It appears this way at first with Silhouette, but later it's revealed that this is just what he looks like.
- What, Exactly, Is His Job?: It's unknown what exactly they are to the empire, let alone Z-Block, but it's likely they're either Dengakuman's aides, or they replaced Kibahage as Dengakuman's deputy commanders since Bo-bobo ate Kibahage five years ago.
Hajike Block (Wiggin' Block)
- Character Tic: He closes out a segment or chapter by doing hand gestures spelling out his initals.
- Cool Ship: Parodied. His "spaceship" is simply a bike connected to a platform.
- Helpful Mook: It's ambiguous if he even works for the Chrome Dome Empire, since all he does is help Bobobo and friends avoid the initial gatekeepers, and even gets them inside Wiggin' Block Base.
- The Bus Came Back: After not being seen since the Wiggin' Block arc, he reappears in Episode 64, having recovered a defeated Rice.
- Animate Inanimate Object: He's strip making machine that's alive.
- Cloudcuckoolander: Compared to the rest of the Block guardians, he acts more like an in-universe Big-Lipped Alligator Moment.
- Creepy Crossdresser: He's a hefty man with a bushy, unkempt, beard and missing teeth who wears a lacy nightie that acts in an incredibly offputting and erratic way, and is introduced cornering Beauty while threatening to read her fortune.
- Horny Vikings: His outfit calls to mind of this, with his headgear looking like the sterotypical Norse helmet with horns on it.
- We Hardly Knew Ye: They get blown away by the wind before anything else can happen.
- Epic Fail: His attempt as the drinker in the round by making a dynamic entry from the ceiling failed due to not having enough rope to come down. When he gets a do-over, he just reused Don Patch's motorbike entrance leading to Don Patch effortlessly defeating him by simply blowing him away with a cannon.
- Harmless Villain: His entire gimmick is tricking others into being confused by his tea tactics, but outside of it, he has no combat abilities- leading to Don Patch unceremoniously shooting him down with a cannon when he used the same tactic he did as an incoming drinker.
- Sadist: He first appears by punishing a tied-up fellow teacup BDSM style for betrayal via having coffee instead of tea and then cut the rope holding them up before that broke them into pieces.
- Ambiguously Human: Speaks in a robotic manner and neither his posture nor expression ever changes, not even when Bo-Bobo attacks him. It's downplayed in the anime, however, where he moves quite a lot, speaks like a regular person and shrieks in pain when attacked.
- Ambiguous Situation: Why exactly he's what Wiggin' Birds transform into if someone's Wiggin' level's too low, is anyone's guess. It also begs the question of whether more than one of him exists, but it's never discussed or shown what would happen if two or more people with low Wiggin' levels touched Wiggin' Birds at the same time.
- Frozen Face: He never blinks and his mouth is perpetually agape. Even when Bo-bobo attacks him, his face stays the same.
- Gonk: Drawn very crudely in the manga.
- Non-Standard Character Design: He's drawn in a far sloppier manner compared to how everybody else looks in the manga, probably to reflect how low the Wiggin' levels of those who summon him are. It's downplayed in the anime, however, where he's drawn in the same quality as everyone else, but still has a more realistic-looking face.
- Bait the Dog: Initially seems to be a cutesy character until he reveals his true nature as psychotic, arrogant sadist when he attacks Beauty.
OVER's Castle
Ruby
The first of the Ultimate Five Assassins. She's a young girl who just wants to play the day away... except it's an assassination tactic where she brainwashes those who play with her, rendering them helpless when goes in for the kill.- Beauty Is Never Tarnished: Downplayed, as she's only attacked once, but it's omitted in the anime. In the manga, Don Patch punches her in the head, driving her into the ground and causing blood to spew out her mouth. In the anime, she stumbles backwards into a hole in the ground, which Don Patch pulls her out of.
- The Ditz: Though much tamer compared to the borderline insanity everyone else expresses.
Infinite Kicker (Infinite Shoot)
The second of the Ultimate Five Assassins. He's a soccer player/ninja/ping-pong player that can start fires with his eyes.- Artifact of Power: Averted. Don Patch steals his soccer ball from him under the assumption that it's the source of his power. Infinite Shoot points out that no, it's just a regular soccer ball, and Don Patch gives it back.
- I Know Madden Kombat: He's a soccer player.
- Ninja Pirate Zombie Robot: A blue-haired, red-eyed, fanged Hair Hunter/soccer player/ninja/ping-pong player/kusarigama wielder that can conjure fire with his eyes.
The Three Major Civilizations
A trio of goofballs, each of which are named after three of the first four major civilizations in the world: the Kouga Civilization (the Yellow River Civilization in the anime's English dub), the leader of the group and the only humanoid; the Indus Civilization, a sentient firecracker; and the Mesopotamian Civilization, a pink octopus-like creature.
- Harmless Freezing: The Kouga Civilization ends up freezing himself solid with his "Freezing Sweat" attack since he isn't immune to it, but is able to break free of the ice and suffer no ill effects. Justified, however, for while he may not be immune to getting frozen, he's still got enough immunity to not suffer badly from the ordeal and break free of the ice.
- Ninja Pirate Zombie Robot: The Mesopotamian Civilization. He's a giant, pink-colored, human-faced sea creature that can walk on land and works as a ninja for a evil empire.
- Required Secondary Powers: Downplayed. "Freezing Sweat", the Kouga Civilization's signature attack, grants him the power to freeze solid anything that comes into contact with his sweat. Unfortunately for him, he isn't immune to the properties of his own sweat, and ends up freezing solid himself whenever he performs the attack. However, he's still able to break free of the ice without suffering frostbite of any other related ill effects.
- Terrible Trio: They fight as a three-man group. In fact, they're the originators of the "group fight" formula in the series, for fights have largely been one-on-one affairs up till the moment the Rebels meet the Civilizations.
- Trap Master: Mesopotamian certainly tries to be one, but every single trap of his is either quickly foiled, completely ineffective, or sprung on himself.
- Barrier Warrior: He can create an energy shield to block Bobo-bo's fireballs
- Portal Door: His mouth acts a literal portal door to OVER's Castle.
- What Happened to the Mouse?: What happens to him after he sucks the Rebels into his mouth to send them to OVER's castle is never shown in the anime. In the manga, he simply poses with N&Ns to end the chapter.
The guard of OVER's Castle.
- Expy: The dub makes him sound like the actual Forrest Gump.
- Wings Do Nothing: He's capable of flight, but apparently it's his antennae that allows him to do this; if it's ripped off, he's permanently grounded despite having wings.
Hallelujah Land (Holy Guacamole Land)
Galubel the Fresh-Blooded (Garbel of Manicura)
The first of the Hell Killers, he faces off against Bobobo, Jelly Jiggler and the others.
- Femme Fatalons: A male example. He manipulates his nails as long ranged weapons.
T-500
The second of the Hell Killers, he faces off against Don Patch.
- Expy: Of the T-800, if his name wasn't enough of a clue.
- The Stoic: He not only plays himself professional at all times, but is the only known character in the series to never smile.
- Not So Stoic: Don Patch's antics causes him to be exasperated as anyone else.
The Three Prison-Murderer Brothers (The Terrible Triplets/The Super Hell Brothers)
A trio of brothers that face off against Bobobo's party and collectively the last and strongest of the Hell Killers. They consist of Haou, a stern, green creature and the eldest brother; Megafan, a man dressed like a pirate who fights with chewing gum and the middle brother; and Beep, a muscular man who wears a mask and the youngest brother.
- Butt-Monkey: Beep continuously gets punished by Bo-bobo's Bo-bobo Roulette technique.
- Good Old Fisticuffs: This is Haoh's entire fighting style.
- Twincest: Beep and Megafan perform a move called "Brotherly Love Energy Recovery", which apparently involves the two of them kissing, but Bo-bobo and Don Patch tickle them before they can actually do it. The original US broadcast cuts before the two start leaning in.
- Strong Family Resemblance: Inverted. Beep and Megafan are both blonde-haired humans, but Haoh is a short green cartoonish oni-type creature with similar body proportions to Don Patch.
An assassin sent by Halekulani to defeat Bobobo.
- Assassin Outclassin': Attempted to assassinate Bobobo in his sleep, only for fight him directly anyway.
- Fate Worse than Death: Halekulani turns him into a coin. After that, he's never seen again. Though, if No Ontological Inertia came into play, he turned back into a human after Bo-bobo defeated Halekulani.
- You Have Failed Me: Halekulani turns him into a coin for his failure to defeat Bobobo.
- Ineffectual Sympathetic Villain: He spends most of his fight being a complete punching bag, even worse for him it's implied he wouldn't have much better chance if the heroes weren't reduced to children.
- Nightmare Weaver: He can bring his opponents nightmares to life. Unfortunately for him, this is useless against the heroes.
- Obviously Evil: He has horns, and oh yeah, the kanji for "Enemy" is written on his forehead. Gasser sees right through him when he tries to act like the team's friend.
- Would Hurt a Child: What'd you expect of a Hair Hunter that hangs around an area that turns everyone but him into kids?
Cyber City
Pana
- Insult to Rocks: "Calling you a threat is an insult to threats!"
- My Death Is Only The Beginning: In his defeat, he tells Bobobo that the other Cyber Knights will not be so easy to defeat before passing out.
- Shock and Awe: He is capable of creating massive lightning balls that drain the energy of anyone attached to them.
- Tornado Move: His primary method of attack is spinning around on his head. Bobo-bo, Don Patch, and Jelly Jiggler attempt to emulate it... to predictably poor results.
Sonic
- Jet Pack: utilizes this as part of his means to keep afloat and his means of combat. He can even utilize a transformation to make him resemble a jet more.
- Surprisingly Realistic Outcome: When the heroes first encounter him, all the blood has rushed to his head from being upside-down for so long.
Shibito (The Bad Bard/The Poet)
The fifth of the Cyber Knights to be introduced and one of the only three with Super Fists. He faces a combination of Beauty, Don Patch, Jelly Jiggler and Torpedo Girl.
- Evil Red Head: Has red colores spiky hair.
- Written Sound Effect: Utilizes them as weapons with the words taking on the powers of their definitions.
Carman (Otto)
The second to last Cyber Knight Bobobo and the others face off against.
- Curb-Stomp Battle: In one of the rare stomps that doesn't involve Insane Troll Logic, Calvinball or Confusion Fu, all of Otto's tactics are met with one-sided demolition of his forces and later a No-Holds-Barred Beatdown for his troubles.
- Ineffectual Sympathetic Villain: He absolutely fails to do anything resembling damage to Bobobo and Softon.
- Non-Human Head: He's got a car for a head, and after his fight with Bobobo, his face gets beaten so badly that it gets turned into a plane.
Wan Ronga
- Fate Worse than Death: Subverted. Hatenko using his "Super Fist of the Key — Eternal Lock" leaves him locked in place as a statue, with Hatenko saying he would stay like that forever, fittingly not returning for the remainder of the series. By Shinsetsu however, he's back to normal and working alongside J attempting to stop the raid on Cyber City by the Neo Maruhage Empire, only to be easily beaten by Porusutoroi and Made a Slave.
- The Unfought: Downplayed. In spite of being the one to bring Gasser to Giga, Bobobo never faces him in combat, but Wan ends up being defeated by Hatenko.
J
He manages to easily defeat Soften and proves to be deadly enough for Bobobo to need to fuse, with J attempting to avoid a confrontation with Bobopatch by having Dengakuman replace Don Patch as the fusion component, only to be defeated by Denbo anyway.
- Affably Evil: Compared to his colleagues, he's a essentially doing his job to protect Cyber City as the sole protector of the power core for the center city and dealing with intruders. He is genuinely respectful to Soften, even aiding him to get stronger after losing to Denbo and is overall well-mannered.
- Casting a Shadow: Utilizes the Fist of the Black Sun, which manifests as dark purple fire with a light blue outline.
- Evil Counterpart: To Softon. He's a stern, soft-spoken man with a Non-Human Head and powers beyond the regular events of the series, it's unknown if J's head is either his actual head or a mask like Softon's.
- Non-Human Head: Bobobo agonizes over whether J's head is an onion or a garlic.
- No-Nonsense Nemesis: J doesn't gloat or waste time like his colleagues, going straight for the kill with trickery and overwhelming force. He immediately tries to avoid a confrontation with Bobopatch by replacing Don Patch with Dengakuman for a potentially weaker fusion and attacks Denbo anyway, reasoning she's the fusion of two guys anyway.
- One-Letter Name: When asked his name, he builds it up by performing some flashy poses before revealing it to just be J.
- Punch-Clock Villain: Compared to his colleagues and his boss, that are sadistic jerks who torment others for their own amusement, J's only concern is maintaining the core of Cyber City and defeating the intruders. While he does fight with trickery, it's more pragmatic than outright sadistic.
- The Worf Effect: J is one of the stronger characters the Rebels have ever fought, so when a new enemy needs to be seen as a threat, he tends to get his ass handed to him. This was the case for the New Emperor Playoffs guardian Menma, and the Neo Maruhage member Porusutoroi.
- Worthy Opponent: Finds Soften to be this.
- Would Not Hit a Girl: Downplayed and Zigzagged. He claims this when he's about to attack Denbo, only to attack her anyway with the rationalization she's a fusion of two guys anyway. He does however does not attack Beauty.
- Expy Their designs are heavily inspired by the Storm Troopers of Star Wars.
- What Happened to the Mouse?: They're never seen again after their initial appearance, and are thus not fought either.
- Curb-Stomp Battle: Once Bobobo convinces Torpedo Girl to fight alongside them, she proceeds to easily demolish them with ease.
- The Stoic: Compared to the rest of Cyber City with the exception of J, the duo present themselves as professionals.
- Meaningful Name: Biki wears a bikini, while Bathro wears a bathrobe.
- Neutral Female: Don't do anything besides hype up Giga, though they attack the Narrator in the anime when he tries to get them to stop praising Giga (and start praising him instead).
- No Name Given: Their names are never revealed, but Word of God apparently revealed at some point that their names are "Biki" and "Bathro".
- Sadist: Not as prominent as Giga, but their resultant giggling at Gasser's forced transformation imply they also enjoy the suffering and humiliation Giga inflicts on his victims.
- Gratuitous English: Invoked. The word "Super" is supposed to be written on his torso, but it's written as "Speer".
- Not-So-Harmless Villain: Initially appearing as a joke, he soon reveals his expert combat skills.
- Brown Bag Mask: His face is entirely covered by a crude paper bag mask.
- The Eeyore: His defining trait is being perpetually depressed.
- Heel–Face Turn: He aids the heroes against the Shadow Chrome Dome Empire in the Playoffs.
Assassination Corps (Enforcer Unit)
- Adaptational Badass: He trades his regular knife for an unnamed technique that allows him to use his hands to release ranged slashes of energy by having his hands do a slashing motion.
- Affably Evil: One of the lesser evil bald members of the Hair Hunters. Killalino puts aside his assassination job to spend his time talking to Takashi/Ducky about his personal issues before resuming his assassination when the conversation was done, having accepted the underwear the way he is. He also takes time off during the Reverse Maruhage Empire Arc, relaxing on a beach
- Bald of Evil: Though has enough heart to have a talk with his duck underwear hat about the latter's uncertainty about his existence, temporally putting his assassination attempt on Bobobo on hold until the issues were resolved.
- Bowdlerise: One of the more infamous examples as Killalino had his duck underwear on his crotch- leading to a very unfortunate Gag Penis gag. The anime censorship had him wear the duck on his head, making his perverted nature not as blatant, but still sell him as a weirdo.
- To a lesser extent, his knife technique in the manga is swapped with an ability to make his hands do knife slicing movements to release ranged slashes.
- Breakout Character: To an extent, he manages to make a reappearance during the Blood Mansion Arc- one of the few original arc villain characters outside of Katsu and Jelly Jiggler to make a significant reappearance in the future arcs.
- Punch-Clock Villain: Implied. He and his duck underwear take the time to have a chat about the latter's personal issues, taking time off the hit on Bobobo- resuming when the issues were resolved. He also takes time off on a beach during the Reverse Maruhage Arc.
- Assassin Out Classin: Despite being little more than a pair of sentient cellphones, they're apparently the Assassination Corps' strongest assassins.
- Informed Ability: They essentially took care of themselves before the Rebels ever got the chance to fight them. But if they really were the Corps' strongest assassins, one could only imagine what the Rebels' battle with them would've been like if Gura didn't get hurt.
- The Unfought: They ended up taking care of themselves with Bo-bobo never even knowing they existed in the first place.
- Killed Off for Real: Bo-bobo fastens shackles with steel balls hanging off of them to his wrists and ankles, then kicks him off the airplane they were fighting on top of. Granted, he could just use his Super Fist to create a parachute and land safely. But considering he's never seen or mentioned again...
- Cartoon Creature: His name's Japanese for "mole", but he looks very little like one.
- Always a Bigger Fish: Is implied by the Czar himself to be even stronger than both OVER and Halekulani.
- Assassin Out Classin: The leader of the Chrome Dome Empire's Assassination Corps.
- Non-Indicative Name: He fights with duct tape, not nunchucks.
The Maruhage/Margarita New Emperor Playoffs (The Bald Bowl)
- Fate Worse than Death: Gets turned into a coin by Halekulani, and is promptly forgotten and left in the tunnel.
- The Worf Effect: Halekulani effortlessly turns him into a coin.
- Beauty Is Never Tarnished: She's the only female Hair Hunter in the first series that's never harmed in any way. Though her pride got harmed when she lost her own contest.
- Expy: Of Usagi Tsukino a.k.a. Sailor Moon, what with her Odango Hair and various poses. The anime's English dub makes it even more obvious by having her voiced by Stephanie Sheh, Usagi's English VA.
- The Worf Effect: Parodied. She managed to defeat J, the strongest of the Cyber Knights... in a ramen-eating contest.
Miscellaneous
- Informed Ability: His name means "big rock", but whether that refers to his powers or not is anyone's guess.
- The Ghost: Parodied. He's only mentioned once in one panel in the very first chapter where the empire's hierarchy map is shown, and but Bo-Bobo never encounters him and he's never seen or mentioned in the story.
- The Reveal: He's revealed to be a tiger in supplemental materials. As in a non-anthropomorphic, realistic-looking tiger.
- Beauty Is Never Tarnished: Subverted. Don Patch punches her so hard that blood spews out her mouth like a geyser and she flies right into the wall of a nearby house.
- Dude Magnet: While Kitty-Poo is in the middle of a long speech, Don Patch walks up to Lemon Fizz and hands her a Love Letter, which she promptly rips in half. Bobobo follows, with the same result. Then Hatenko gives her one, resulting in a Luminescent Blush and her happily opening it, only for it to be a note asking her to return a manga volume he lent her a year ago.
- Expy: She's the Zarbon to Kitty-Poo's Frieza.
- Fan Disservice: She's a fairly pretty girl and you're able to get a look at her panties in the manga... except this happens the same time Don Patch punches the hell out of her and causes blood to fly out her mouth. Also, the last time you see her in the manga proper is shortly after Don Patch attacks her: she's on the ground, surrounded by debris and with a look on her face implying Don Patch knocked her unconscious.
- Informed Ability: According to Kitty-Poo, she's stronger than Captain Battleship. Since she, Kitty-Poo and Chocolate Munchie are all promptly defeated by Don Patch in one fell swoop, this power is never demonstrated.
- Bowdlerize: His appearance is this in the anime. Initially, he was a box of cigarettes before being altered into a box of chocolates.
- Expy: He's the Dordoria to Kitty-Poo's Frieza.
- Bald of Evil: Subverted or Play straight. He either has a large clump of hair on his head or wore a winter hat to cover his head during the skiing.
Video Game Exclusive
- Accidental Misnaming: Nice Guy apparently cannot remember people's names, so he refers to everyone as "Tanaka".
Jail wields the Super Fist of the Black Chain, which allows him to attack his enemies with an endless amount of chains.
The Former Maruhage/Margarita Empire (The Former Chrome Dome Empire)
The third era of the Chrome Dome Empire, which was led by Czar Baldy Bald III. For reasons unknown, Baldy Bald III and all twenty-six of his Block leaders were put in cryogenic chambers, where they slept for 100 years. Now the Block leaders are awake, Baldy Bald IV sees this as a chance to defeat Bo-bobo once and for all. So Baldy Bald IV creates Neo Hair-Hunt Land MAX, yet another amusement park that doubles as a battleground, for the Block leaders to dwell in and fight the Rebels while Baldy Bald III continues to rest until it's time for him to take center stage.
- Always a Bigger Fish: Though they ultimately fail to stop the Rebels, they're still much more formidable than the various groups from the empire's fourth era, often forcing Bobo-Bo and his gang to break out all sorts of new tricks to defeat them.
- Badass Army This entire generation of soldiers is described as such, having conquered almost all the known world in four days.
- Hypocrite: Once again, despite the fact they're dedicated to ridding the world of hair, a good deal of their members have full heads of hair. Even Baldy Bald III, robot or not, has hair.
- Oddly Small Organization: They don't have the various factions and subsidiaries of Hair Hunters the fourth era has. It's just Baldy Bald III, his 26 Block leaders, Rose-Lily's five Hair Hunters, and the two Hair Hunters that encounter Baldy Bald IV, bringing the amount of members they've got to a grand total of 34. That said, they aren't pushovers and came very close to defeating the Rebels.
- Older Is Better: In the current fourth generation, the Hair Hunter regular troops and their commanders are mostly pushovers to a skilled Fist user with the exception of A-Block, with a lot of the power reliant on the Big 4, Giga's Cyber City, some assassins, and Dark Yasha- with the current Czar proving to be inept in terms of leadership and physical ability even discounting the fact he's merely a figure head for Bibibi. The Third generation, its direct predecessor, are significantly more powerful, with a select number of regular Mooks being as difficult a threat as one of the Big 4/Cyber City's Quirky Mini Boss Squad, with the Hair Hunt Block commanders, individually requiring Bobobo to need a power-up to defeat them, and a Fusion Dance to defeat the three strongest ones. Their leader, a very powerful fighter with not one, but two Super Fists not only proves to be a difficult challenge requiring OVER of all people to aid, but briefly puts Bobobo in a corner, and manages to become the much more efficient Big Bad of the Time Skip with a much more competent empire under his leadership once he gains a Hair Ball to reestablish his leadership.
- Older Than They Look: They've been put in cryogenic sleep chambers for 100 years so however old they appear to be, add 100 years to that.
- Suspiciously Similar Substitute: They've got their own versions of the fourth era's block leaders. For example, Jeda the Wind God and Rose-Lily Kikunojo are essentially their era's versions of the fourth era's Geha the Gale and Hagen.
- Arc Villain: Of the Former Hair Hunters arc, uniquely, he manages to ascend into the Big Bad role for the Time Skip by finally obtaining the Hair Ball from Bibibi.
- Always a Bigger Fish: Much, much worse than Baldy Bald IV and Hydrate
- Big Bad: Of the Former Hair Hunters arc and Shinsetsu.
- Clipped-Wing Angel: Played with, His absorption of Bobobo and Don Patch does give him the powers he craved....., but made him change into a pink Cartoon Creature, which was not his intention. Subverted with his later attempt with Bibibi that results in a far less humiliating form.
- Cherry Tapping: Ultimately defeated by Bo-bobo giving him a light chop to the armpit in Shinsetsu, after the standard arc-ending montage attack.
- Creepy High-Pitched Voice: In the English dub, he has a dissonantly higher-pitched voice that contrasts with his more regal appearance, which gives him an uncanny eeriness even before the Robotic Reveal. Averted in the original version, where his voice is appropriately deep.
- Deconstruction: Of the Cruel Mercy trope. Bo-bobo's chosen to let every Hair Hunter up to this point live, likely because he sees them living with the knowledge they were defeat by him to be a Fate Worse than Death. Either that, or he believes that they've still got a chance to change their ways. Tsurulina III takes the fact Bo-bobo let him live as a chance to commit even more atrocious acts, to the point where he revives the Chrome Dome Empire in Shinsetsu and tears through the Hair Kingdom, where he kills Bi-bibi and absorbs his Hair Ball. Needless to say, Bo-bobo should've killed him when he had the chance.
- Evil Sounds Deep: Played straight the original Japanese version, courtesy of Ryōtarō Okiayu that gives him a suitably deep and regal voice. Subverted in the English dub, which gives him a much higher pitch voice.
- Fantastic Racism: Considers humans nothing but scum.
- Genre Refugee: He wouldn't be out of place in a regular fighting shounen manga, as he stands out for being completely serious and ruthless. The only other antagonist who comes even close to him is Bibibi.
- Goofy Buckteeth: He once turned into a weird humanoid-like creature complete with a bucktooth after swallowing Bobobo along with the Hairball.
- Hollywood Cyborg: As it turns out, he's truly some sort of android with a human exterior, revealed when he was injured for the first time as part of a Robotic Reveal and later briefly as his skin peels off to reveal his robotic form just before His Clipped-Wing Angel.
- Hypocrite: Robot or not, he's the leader of an empire that wants to rid the world of hair, yet has head full of red hair.
- Ignored Epiphany: After Bobobo goes to get efforts to show a technique to show him the wonders of humanity, he still decides to Take Over the World and make it worse than before.
- Kick the Dog: He has a roulette attack just to target Bobobo's friends one by one until they were destroyed.
- Kick Them While They Are Down: kills Bi-bibi and steals his Hair Ball after Bo-bobo has defeated him, paving the way for his rise to power and the sequel series.
- Knight of Cerebus: A misanthropic megalomanic whose first action against Bobobo is to immediately try and kill him, and decided to slowly kill off his friends once he finds out that he is a Living Macguffin. Not something you'd expect from odd series like this. He becomes more of this in the Time Skip, leading the series to be slightly Darker and Edgier.
- Lack of Empathy: When confronted by Bobobo after pushing his Berserk Button"Do you think I care?"
- Leitmotif: A subtle, but noticeable organ is played twice in his fight during his dark moments.
- Not Even Human: Upon absorbing the Hair Ball in the first fight with him, he reveals his true form to be a robotic demonic being.
- No Indoor Voice: He practically screams all of his lines in the dub.
- Our Robots Are Non Standard: Being an android and all.
- Robotic Reveal: The reason why we know he's one.
- No-Nonsense Nemesis: Has little to no quirks compared to his underlings and his reaction to any comedy is to ignore and continue to try to kill someone.
- Not-So-Harmless Villain: In the context of the story, he was the latest Arc Villain to defeat, which made his refusal to give up his evil ways, leading to him returning to become the Big Bad of the Time Skip.
- Order Versus Chaos: seeks an entirely ordered world where those who do not obey his every command are dead.
- Pay Evil unto Evil: Does this to Bibibi, who started the entire current generation of the Hair Hunt operations that wiped out his original civilization, temporally murdered his own family and had been a Big Brother Bully to his younger siblings even prior to this. He takes his Hair Ball, temporarily killing him and leading into the events of the Time Skip, but the killing was seen as well-deserved punishment as Bobobo had let Bibibi off the hook too easily after defeating him.
- Person of Mass Destruction: In his introduction, he throws a few knives off into the distance. The result is something ripped right out of Dragon Ball.
- Primary-Color Champion: Inverted HARD. His color scheme consists of primary colors, such as red hair and blue eyes, the yellow phoenix tattoo on his forehead, as well as his blue coat, red shoulderpads, and yellow belt, but he's the single most serious, ruthless, and dangerous villains in the entire series
- Sealed Evil in a Can: He rest for 100 years prior to his awakening.
- Superpower Lottery: Notably, he's the only main villain to not have just one, but two Super Fists, Red Magic that deals with physical stage magic based attacks and Blue Magic that focuses on mental degradation based attacks.
- Vocal Dissonance: He has a very loud, high pitched voice in the English dub in contrast to his regal and intimidating appearance. It foreshadows the artificial quality of him, once it's revealed that he's a robot underneath his appearance and is incomplete without a Hair Ball.
- Ungrateful Bastard: A very notable example considering most of the villains become allies at this point Despite Bobobo sparing his life, he decides to screw everyone over by taking Bibibi's Hair Ball and reestablishing his empire for the Shinsetsu Time Skip series.
- Vile Villain, Saccharine Show: He's a cybernetic, misanthropic megalomaniac with no hesitation in committing atrocities in order to maintain his authority. He stands out since most of the series involves light-hearted yet bizarre comedy, and is the sole reason after getting the Hair Ball that he manages to make the series Darker and Edgier with his new abilities.
The First Seven Block Commanders
After joining up with the Rebels, he fights with "Hanpen Jujitsu", a goofy, but powerful form of martial arts.
- A Father to His Men: Treats his allies with more respect than Bo-Bobo does his own.
- Blood Knight: Although he was confident he was superior and later fights for his comrades, Hanpen likes a good fight.
- The Dragon: To Czar Baldy Bald III.
- Heel–Face Turn: Much like Jiggler before him, Hanpen sides with the Rebels after getting defeated by them, choosing to fight alongside them during the Bald Bowl.
- Non-Human Head: His head is a fishcake with a face, and he apparently used to be just a fishcake.
- Redemption Demotion: Not as bad as Jelly Jiggler, but he's much less useful as a hero than he was as a villain.
- Social Darwinist: He harks on about the worthiness of his opponents.
- Suspiciously Similar Substitute: To Jelly Jiggler, being an eccentric, anthropomorphic foodstuff and the leader of his era's A-Block, who joins the Rebels after being defeated by them and is treated as a joke for the remainder of the series despite being a powerful fighter in his own right.
- Blade Below the Shoulder: His Polygon Lance ability turns his hands into low-polygon lances that can fire sword beams.
- Crossdresser: Forced into being a princess when trapped in a Final Fantasy parody.Lambada:Why am I dressed like a colorblind prom date!?
- Cross-Dressing Voices: In the English dub.
- Determinator: According to Rem, he once had a stare-down with General Lee Fishcake until the General passed out.
- Forced Transformation: Can turn people into low-polygon versions of themselves, or even into other things. He tries turing Bobobo into an ugly pig, but the attack turned him into a handsome pig instead. He tried the same attack on Don Patch and Jelly Jiggler, but somehow they're turned into a talkshow host and a dragon, respectively.
- Jerk with a Heart of Gold: He's not so much a jerk but he is serious and aloof. However, underneath, he's pretty caring, especially towards his allies.
- Logical Weakness: His Super Fist of the Polygon is unable to function when trapped in pixelated video games, which do not use polygons for their graphics.
- Blow You Away: As per his powers as a wind god.
- Clipped-Wing Angel: His forced fusion with Baron Von Horny, results in a ridiculous form that makes all of his attacks ineffective.
- Humiliation Conga: Once Patchbobo is formed, Jeda's competency as a fighter is torn to shreds by the fusion, the worse was being fused with Baron Von Horny, resulting in a form that makes all of his attacks useless on top of looking ridiculous.
- Merging Mistake: The pinnacle of his humiliation was being fused with Baron Von Horny into a silly form that makes his attacks completely worthless.
- Sinister Scythe: He summons one for his "wind scythe" attacks.
- Suspiciously Similar Substitute: He's the former Chrome Dome Empire's answer to Geha the Gale, being the leader of C-Block and having wind-based powers.
- Abusive Parents: According to the manga, her parents (two beds) used to beat her.
- Defeat Equals Friendship: As with a lot of Bobobo's foes, she turns good after being defeated.
- Heavy Sleeper: She struggles to start her battle because she can't stop falling asleep. Even in mid-battle or MID-AIR she'll fall asleep.Rem: Just five more minutes...
- Heel–Face Turn: The entire latter half of Bobobo's battle with her involves melting her heart and turning her good.
- Meaningful Name: As in "Rapid Eye Movement", a stage of sleep.
- Mind Screw: Some of her background, is that she's the rather human offspring of two beds. Thinking about that might make your head hurt.
- Power Dyes Your Hair: In her Berserker form, her hair turns from white to lavender and her eyes turn pink.
- Power Makes Your Hair Grow: And gives you a jacket.
- Troubled Backstory Flashback: Apparently, she's actually the daughter of two beds. During her childhood, she was mocked by the other bed children.
- It's worse in the manga, she was BEATEN BY HER PARENTS.
- Stripperiffic: Yet no one really cares.
- Suspiciously Similar Substitute: She's the Kitemasu of the former Chrome Dome Empire, due to having a sleep Motif (Rem's narcoleptic, while Kitemasu wears pajamas).
- Covert Pervert: His two subordinates are two girls in swimsuits, and he's able to get back up if they cheer him on.
- Drill Sergeant Nasty: In the English dub, he speaks in a stereotypical drill sergeant fashion.
- Face Ship: Has a cargo helicopter with a cockpit shaped like his head. It even ejects crates out of the mouth!
- Hidden Eyes: His helmet casts a shadow over his eyes.
- Me's a Crowd: Can create two clones of himself.
- Piranha Problem: Claims to summon them through his Piranha Hell attack. Except they're actually harmless sunfish.
- Trap Master: He uses the Super Fist of Trapping.
- Beard of Evil: Somehow sports one, despite having an inorganic object for a body, and it's depicted as a black ring around his mouth.
- Elemental Powers: Oddly enough, fire, in the form of the Sun, which leads to him being a Joke Character.
- Heel–Face Turn: In order to get past a guard, he sides with Don Patch and Beauty. This lasts about five minutes before a Face–Heel Turn.
- Joke Character: He's a bowl of shaved ice, and has the Fist of Summer. This does not end well for him.
- One-Winged Angel: Capable to transform into a Death Star-esque version of himself
- Punny Name: Doubling as a Meaningful Name, his name is a play on "ujikintoki", Japanese shaved ice.
- Self-Disposing Villain: He suddenly returns for a second round during the Giant Coin Game Winner-Takes-All Stage fights, only to jump straight into the Recycler and immediately is ground up into an ice statue.
- Gender-Blender Name: With a name like "Rose-Lily", you'd think he was female.
- Green Thumb: The Super Fist of Blooming Flowers allows him to create giant roses and man-eating plants out of thin air.
- Kick the Dog: When he begins his Hair Hunt, he uses an indiscriminate attack, something Nihiru points out in fear. Kikunojo coldly tells him You Have Failed Me before deliberately attacking him, this case of Friendly Fire being played entirely for horror.
- Suspiciously Similar Substitute: To Hagen, being an effeminate man who leads G-Block and the very first major player of his era of the empire the rebels fight and defeat.
- Uncertain Doom: He's the only major former leader to never return after being defeated by the Rebels, last being seen slammed head first into the sands of Egypt. With him being one of the few people Bo-bobo has fought that he considers "pure evil", it's not hard to think that he actually killed Kikunojo with his last attack.
- Wake-Up Call Boss: Manages to be this, pushing Bobobo to a corner before he reverses it with his Super Bobobo powers.
The Other Block Commanders (in Block order)
- Meaningful Name: In the original Japanese, he's named after a kind of fishcake that he looks like.
- Equippable Ally: Parodied, at a point during the fight Hanpen uses him as armor, it proves to make him unable to move and it didn't protect him from any attack.
- Unexplained Recovery: Tenbobo cuts his head, however he's fine in the next shot.
- Signature Sound Effect: The sound of bells ringing is heard whenever he attacks in the anime, which likely comes from the bells affixed to his hat moving about whenever he's in action.
- Heel–Face Turn: Though they weren't exactly evil to begin with, they're convinced by Bobobo to be good, without any hesitation from them.
- Nice Girl: Both of them. Even when they work under Major Minor, they don't actually do anything to harm the heroes, they just play with each other in the pool and cheer on Major Minor when he needs their support. Bobobo convinces them to abandon the Major and fight for good extremely easily.
- Furry Reminder: A variant (as he's not an animal) but he is a vampire and will suck blood and attack with biting. Of course, while he can suck blood, he can't do that with stuff that isn't blood, as he found out with Jiggler (who's made of jelly)
- Our Vampires Are Different: The sunlight doesn't bother him.
- Anime Hair: His is downplayed but, for some reason, he has black hair other than blonde his ponytail.
- Walking Shirtless Scene: He has no clothing over his upper torso.
- Meaningful Name: He fights with technique derived from "3,000 years of Chinese History" (read as "flying ramen bowls").
- Only Sane Man: The only competent member of his squad.
- Lorre Lookalike: For some reason, his English voice is a Peter Lorre impersonation.
- Megaton Punch: Fights with his boxing gloves with this intended effect.
- Ambiguous Situation: Why he looks like Haoh is anyone's guess, but it's likely he's just Haoh's ancestor.
- Cartoon Creature: It's hard to describe what he is, only that he has a strong resemblance to Haoh from the Halekulani arc.
- Non-Indicative Name: His Transforming Mecha's Eagle Mode... is an elephant.
- Reused Character Design: Looks a lot like Haoh but with longer horns, one extra horn in the middle of his head and angry eyes, although this is never commented on.
- Suspiciously Similar Substitute: To Haoh of the terrible triplets. He looks like a more devilish version of him and is the most competent member of his team.
- Curb-Stomp Battle: He delivers one to Tennosuke and on the receiving of a colossal one by Don Patch.
- Enemy Summoner: Can summon monsters to fight for him.
- Enemy Scan: Has an telescope that allows him to do this, unfortunately for him it is totally useless against Don Patch.
- Even Evil Has Standards: When Don Patch fishes Jelly Jiggler back into the fight, Roman Samurai chastises him for breaking the rules.
- Historical Domain Character: He's revealed to actually be Ishikawa Goemon, a well known outlaw akin to Robin Hood. Overlaps with Historical Villain Upgrade, as the real Goemon was famous for his attempt at assassinating the tyranical Toyotomi Hideyoshi, whereas this Goemon was a Block commander of the tyrannical Chrome Dome Empire.
- I Have Many Names: When he first appears, he's referred to as "Romantic You". It's only after a little while longer his actual name, "Ishikawa Goemon", is revealed.
- Named After Somebody Famous: He's likely named after "Yagyu Munenori", a famous swordsman from the Tokugawa Era.
- Stupid Evil: Invoked. At least the likes of Bo-bobo and Don Patch have the excuse of their stupidity being an actual in-universe combat technique. Yagyuu's so stupid and hardheaded that it's not even funny.
- Gonk: Despite how much of a Bishōnen he thinks he is, he's quite the visually unappealing fellow: he's got a pair of massive eyes that look like holes; no visible neck, eyebrows, or ears, and an ugly haircut.
- Joke Character: The only former Block commander to be no threat whatsoever, as his only "power" is holding fashion shows.
- Pretty Boy: Parodied. He styles himself as a pretty boy model, but is actually more in line with a Gonk in terms of appearance.
- Ass Shove: His special attack involves shooting himself up a person's asshole at high speed, giving them immense pain.
- Did You Just Punch Out Cthulhu?: The fight with Hydrate was was very one sided till he does an epic Ass Shove to him.
- Heel–Face Turn: In the Reverse Margarita Arc, aiding Bobobo and others, notably turning the tide of battle against Hydrate.
- They Killed Kenny Again: It's noted that whenever he tries to use his attack, he will die afterwards, with the one that stabbed Jelly Jiggler in the ass being found to have died after it was removed. Despite this, he shows up alive and well numerous times later with no explanation. It's later revealed that each time he "died", another one took his place, with Don Patch visiting a graveyard entirely devoted to his species... before grabbing the visiting ones and putting them in a bag for later use.
- Almighty Janitor: Averted, unlike his current counterpart, he's not secretly the strongest commander, but he is significantly stronger than the latter in physical ability and technique.
- Curtains Match the Windows: He has yellows eyes to go with blonde hair.
- Goggles Do Nothing: Exaggerated and parodied. He has three goggles on his head and one giant pair on his torso.
- Sdrawkcab Name: Abubul, as in "a bubble."
- Offscreen Moment of Awesome: Torpedo Girl manage to defeat all of them offscreen.
- Ridiculously Average Guy: Assuming that theirs looks were changed for the sake of the joke, all of them like bland, featureless humanoids, which is stark contrast to the varied designs of the other Hair Hunt Troop leaders from 100 years ago.
- Series Continuity Error: Due to an animation error, when the pile of Block leaders are shown, there are six of them when there should only be five of them.
- The Worf Effect: Their existence is to essentially show how strong Torpedo Girl by managing to defeat 5 former Hair Hunter troop commanders from 100 years ago with ease while the others were met with some difficulty.
Rose-Lily Kikunojo's Hair Hunters
- Breath Weapon: He can breathe fire.
- Fat Bastard: Round and is a villain working with the villainous former G-Block commander from 100 years ago.
- Informed Ability: He says that he specializes in underwater battles in attempt to drag Gasser and Jelly Jiggler into the water, only to be countered by Bo-bobo riding a boat to crash him in.
- No Celebrities Were Harmed: The dub makes him sound like Ringo Starr from the The Beatles. He even calls Jelly Jiggler a Blue Meanie.
- What Happened to the Mouse?: He was last seen watching in awe and horror as Bo-bobo beat Kikunojo, before straight up vanishing afterwards.
- My Friends... and Zoidberg: He admits he only joined to hitch a ride, and aside from suggesting Beauty might be the Hair Kingdom survivor, the only thing he really does is play Shogi with Dengakuman.
- Non-Action Guy: He doesn't really fight in any manner, just plays Shogi with Dengakuman. Makes more sense with the fact he's not an actual Hair Hunter, just an otter that hitched a ride with them.
- Cool Sword: He has a sword like the samurai he is named after.
- Eyepatch of Power: Not that it did any good against Soften.
- All Webbed Up: She has powers to create spider webs to trap or to bind her enemies as well as support her allies.
- Dark Action Girl: She's a girl who happens to work during the Third Era of the Chrome Dome Empire.
Miscellaneous
- Almighty Janitor: The two of them are only rank and file Hair Hunters from their generation, but both were still chosen to be sacrifices for Hydrate's resurrection of Yami King, alongside known powerhouses like Giga, Jeda, Haou, and Lambada, suggesting they have energy of similar levels to the four of them.
- Beware the Silly Ones: #6 may be a cute gumdrop-like creature with a big smiley face, but he's still a bloodthirsty solider working for an evil empire.
- Bowdlerise: #5's method of threatening Baldy Bald IV was softened between the manga and anime. In the manga, he pulls out a butterfly knife and has it pressed against his neck, all but saying he'll slash the Czar's throat open. The anime changes this to him just pressing two fingers against the Czar's neck with energy surrounding them.
- Dissonant Serenity: #6 keeps a perpetual cheerfulness in spite of being unashamedly bloodthirsty.
- No Name Given: Neither are actually addressed by name, with their numbers only being known due to being on their reanimation pods.
- The Worf Effect: Mere foot soldiers, yet they intimidate Baldy Bald IV enough to release the third era Block leaders from their slumber. They end up on the receiving end of it once the Reverse Maruhage Empire appears, though, where they're sacrificed to further Hydrate's goals.
- The Unfought: The only two Hair Hunters from the former empire the Rebels never fight.
The Reverse Maruhage Empire (The Shadow Chrome Dome Empire)
- Always a Bigger Fish: They effortlessly overthrow the already cornered Chrome Dome Empire, forcing the current leader to escape in disgrace, and take over the main villain role until the New Hair Kingdom arc.
- Darker and Edgier: They wield "Dark Fists" instead of Super Fists, which turn them into more powerful forms imbued with their normal techniques' power while enhancing their own
- In a more general sense, compared to the regular Chrome Dome Empire that range from silly to serious, the Shadow Chrome Dome Empire are portrayed as a more serious threat, which force the heroes to enter fusions or use entirely new techniques to defeat the enemies. Additionally, their membership includes a member that was brainwashed into servitude, a dominatrix with blatant sexual themes, and a crazed mass-murderer since he was a youth, which already is darker than even the worst of both generations of the Chrome Dome Empire with the sole exception of the III.
- The Worf Effect: The take the same Hair Hunters the Rebels spent countless chapters fighting against and demolish them like they're nothing.
As dead serious as he and his empire is, Hydrate wields arguably the strangest Super Fist in the series: the Super Fist of the Foot Sole.
- Always a Bigger Fish: Much more powerful than his brother could ever hope to be.
- Big Bad: Takes over his older brother's role during the story arc.
- Comically Serious: Despite being even more evil and more powerful than his brother, he's not above using wacky items and his Shinken. Lampshaded by Beauty:Beauty: Is this guy really a dark-series character?!
- Conflict Killer: His interrupting of the Bald Bowl pretty much calls off the war on the regular Chrome Dome Empire, as the Rebels join forces with the empire to take on Hydrate and his regime, and Bo-bobo goes the Hair Kingdom to face Bi-bibi after defeating Hydrate, completely forgetting about Baldy Bald IV.
- Eviler than Thou: Much more menacing than Baldy Bald IV.
- Evil Overlord: Desired to be this since his childhood, but Bobobo manages to defeat him before he gets too far. However, he manages to be infinitely more confident than his older brother ever was.
- Heart Is an Awesome Power: He uses the Ura no Ashi Shinken, the Fist of Foot Sole which is exactly that.
- Interim Villain: He more or less interrupts the plot with his invasion, as his plans have nothing to do with the conspiracy surrounding the Hair Kingdom, and neither he nor anyone from his empire returns after he's defeated.
- Plot-Irrelevant Villain: Though a genuine threat in their own right, Hydrate is ultimately this, as he has nothing to do with the Hair Hunt or the Hair Kingdom conspiracy, and the race to stop Bi-bibi would've more or less gone the same were Hydrate not in the story at all.
- Powered Armor: Exaggerated. He goes through three different armors during his battle: the "Nyan-Nyan Armor" (a.k.a. cat pajamas), which somehow make him Nigh-Invulnerable apart from an Ass Shove by Kancho-kun and Dengakuman's power, of all people; the "Aburage Armor", which consists of a wooden bra and loincloth; and the "Dark Necros Armor", which makes him even more Nigh-Invulnerable.
- The Reveal: It is revealed that his trainer was Landmine Dandy, Torpedo Girl's father.
- Smelly Feet Gag: Weaponized in his Fist of Foot Sole techniques.
- The Unfavorite: He was passed over his brother to be the fourth czar.
Hydrate's Right- and Left-Hand Men
Hydrate's right-hand man, he initially presents himself as a stoic, but it is revealed that he masks his truly psychotic side and he slaughtered the Babylon tribe when he was just a child.
He wields the Ope Shinken (The Super Fist of Surgery), which allows him to fully embrace his sadistic tendencies by being able to cut anyone and everyone open with scalpuls and other such surgical intruments.
- Ax-Crazy: He has a very bloodthirsty, insane, and sadistic personality- even by the show's standards side when the battle goes long, forcing the fight to go from a 3-on-3 to everyone against him to stop him once and for all. He wiped out almost the entire Babylon tribe as a child to sate his bloodlust and he's Unlike the usual craziness of the show, his insanity is played dark and disturbingly straight.
- Body Horror: He has dolls surgically attached to his body that he can harm to hurt others or attach them to his victims' bodies in order to harm them with it.
- He can also tear out the heart of a victim and remove bones from his bodies to harm himself.

- Creepy Child: He was sadistic and psychotic then as he is now.
- Evil Genius: Although he shows more of this in his fight.
- Evil Red Head: While it was apparently due to him being the right-hand man of a man planning on making tyranny more apparent, the full scale of his evilness is revealed when he reveals himself to be a Mad Doctor and Sadist
- Genre Refugee: Even when compared to his fellow Knights of Cerebus, OVER, Halekulani, Giga, and Tsuru Tsurulina III, he stands out as being startingly out of place due to being completely and utterly psychotic, and fighting in an extremely gruesome and bloody fashion, with his backstory detailing that he straight up MURDERED everybody in the Holy Land of Babylon when he was just a child. He's less of a character from a regular fighting manga and more of a character from a fighting manga with HEAVY horror elements to it, if not a hororr manga itself.
- Hero Killer: Of the entire land of Babylon except for Softon and another
- Knight of Cerebus: While the usual hijinks of silly craziness ensue, his murderous, sadistic, and psychotic true nature is played alarmingly straight compared to the usual rogue gallery.
- Mad Doctor: With his Fist Of Surgery.

- The Stoic: Initially leads one to believe this until...
- Not So Stoic: He reveals himself as a psychotic sadist.
- Sadist: Not only is he a sadistic monster that's been murderously insane since childhood, but his fighting style is centered around himself harming dolls surgically attached to himself or forcing them on the bodies of others in order to inflict damage on them.
- The Sociopath: He's able to mask his nature initially as a serious, no-nonsense individual to hide his true sadistic nature, has been impulsively killing since he was in his youth, and has no guilt for his heinous deeds. Byakko is a surprisingly dark villain that contrasts with the usual silliness of the show
- Vile Villain, Saccharine Show: Even when compared to Czar Baldy Bald the III before the Timeskip, Byakko is a dark and disturbing character that contrasts with the shows' usual silliness. A psychotic murderer from a young age that massacred an entire tribe and has a fighting style that is built around grotesque surgery, sadomasochism, and murder.
Hydrate's left-hand man. He is actually Bobobo's older brother, and the wielder of one of the five hair-based Super Fists, the Super Fist of the Leg Hair.

The Reverse Four Heavenly Kings (The Shadow Big Four)
- BFS: Can manifest these as projectiles, but his transformed state allows him to wield one perpetually.
- The Brute: As powerful as he is, his fighting style amounts to little more than flinging giant swords at his opponents. It gets even worse once he becomes Halon Oni 2, where he more or less just thrashes about with his massive BFS.
- Cool Sword: His Fist of the Dark Sword revolves around, well, swords.
- Fate Worse than Death: Subverted. He gets struck by lightning and inexplicably transformed into a Baby Patch, but he doesn't seem to mind it.
- Kick the Dog: He took out his partner, Slim, with his Fist and shows no remorse since he said that he couldn't properly use him.
- Knight of Cerebus: Halon Oni's very presence signals the end of not only the Bald Bowl, but the regular Chrome Dome Empire's reign, as Hydrate makes his move to take over the surface world after Halon Oni's defeat.
- One-Winged Angel: In desperation, he fuses with his own Fist to transform into "Halon Oni 2", a grown-up version of himself with a BFS.
- Throwing Your Sword Always Works: He flings the aura swords he summons like spears at his opponents. He kicks this habit after his fuses with his Fist, where he properly wields and fights with a giant sword.
- What Happened to the Mouse?: Despite becoming one of Don Patch's followers, he never appears again. Nobody from his own empire seems to care, either, despite the fact he was one of their highest-ranking members.

- The Baroness: She's very domineering and likes using her sexual appeal to dominate others. She even reveals a domantrix outfit when it's her turn to fight.
- Dark Action Girl: She's the last and possibly strongest of the Four Heavenly Kings of the Reverse Margarita Empire to be faced.
- Hoist by Her Own Petard: When she uses her powers to affect OVER, it annoys which light his one anger orb up (with Jelly Jiggler lighting all the other five in one act!). This results in turning back into Torpedo Girl and since LOVE's Dark Fist can't work on her own gender, this leads to her downfall.
- Lust: Has a thing for muscles. Much to Over's chargin.
- One-Winged Angel: Transforms into a large griffin which doesn't have anything to do with her Dark Fist!
- The Smurfette Principle: The only prominent female member of the Shadow Big 4, let alone the Shadow Chrome Dome Empire.

Block Leaders
The Neo Maruhage Empire
The fifth and final era of the Chrome Dome Empire and the main antagonistic force of Shinsetsu Bobobo-bo Bo-bobo, created by Czar Baldy Bald III after recharging his power with Bi-bibi's Hair Ball.
- Darker and Edgier: This era's still got their fair share of goofballs, but it's still far deadlier than the eras that came before it.
A student at Ramen High School that appears early in the story. He continues the original theme of bodily function-based abilities with his Super Fist of the Wobbly Tongue. With it, he can use his tongue as an extra appendage and attack people with it, and can even add his saliva into the mix.
It's later revealed by Tsurubinya that Namerou was born with a powerful aura. That aura serves as proof that Namerou is the true heir to the throne, and that he'd one day rule the Maruhage Empire after Baldy Bald III. Tsurubinya decides to speed this along by unlocking Namerou's aura, causing Namerou to proclaim himself "Emperor Tsuru Trusulina V". Namerou than gains the Super Fist of the Emperor, which allows him to channel his aura in the form of attacks that kill his opponents instantly.

The Nine Experts
Hiragi
Jaty
Hiragi's assistant and a doppelganger of Beauty, who came into existence one night when Beauty was alseep. She's the exact opposite of Beauty in every way, being far more mean-spirited, stone-faced when bizarre things happen around her, and even having her own Super Fist: the Super Fist of the Cold Straight Man.Her Super Fist is a reversed, weaponized version of the regular Beauty's role in the series: Jaty forces others to react to bizarre situations, all while lobbing ice-themed attacks at them.

- Meaningful Name: Jaty's name is the Kanji for "evil" (邪, pronounced ja) with the last two letters in Beauty's name added at the end.
- Sitcom Arch-Nemesis: She really hates Don Patch, which is likely derived from the way Don Patch treats the real Beauty.
