    Baby Bowser
Debut: Super Mario World 2: Yoshi’s Island

Baby Bowser (also known as Baby Koopa) is just that: Bowser Koopa as an ill-tempered young tot. Even as a youngster, Baby Bowser was often up to no good, causing lots of trouble for the inhabitants of Yoshi's island and frequently kidnapping the baby forms of his future rivals: Mario and Luigi. He’s the main antagonist of the Yoshi’s Island series, and has appeared as a major antagonist in other Mario games like Mario & Luigi: Partners in Time. Not to be confused with his future son, Bowser Jr., whom he greatly resembles.

Tropes associated with Baby Bowser:
  • Alliterative Name: Baby Bowser.
  • Attack of the 50-Foot Whatever: He grows to gigantic proportions in his iconic boss fight in the original Yoshi's Island.
  • Baby Talk: He seems to have an inconsistent age throughout the games he appears in, as in some games his speech pattern sounds normal, like in Mario & Luigi: Partners in Time, and other games it's more babyish, like in Yoshi's Island and Yoshi's New Island.
  • Black Bead Eyes: Like most baby characters, Bowser had these, his true eye color (red) not becoming apparent until adulthood.
  • Bratty Half-Pint: Spoiled to the core, Baby Bowser is just as ego centric as his adult form, constantly demanding things and throwing tantrums the moment he doesn’t get his way. He even insults his older self at several points, calling him a fat old geezer who should have taken over the world by now.
  • Breath Weapon: In contrast to his future son, Baby Bowser is skilled at breathing fire in every depiction he’s in, and in Yoshi's Island DS it’s even his special ability when selected.
  • Card-Carrying Villain: He's so obsessed with being evil that at one point he only drinks a glass of milk when he's told it was taken from an "evil cow".
  • Divergent Character Evolution: Inverted. Though they've always looked more similar than different, Baby Bowser used to have a few noticeable differences from Bowser Jr. Starting with Mario & Luigi: Partners in Time, he's redesigned to look almost exactly like Bowser Jr., except for his blank white bandanna, and his voice clips are even recycled from Bowser Jr. In Yoshis New Island, he lacks the bandanna, but now uses Bowser Jr.'s exact in-game model. They diverge a bit in Yoshi's Woolly World, however, with Baby Bowser reverting to his older body proportions and posture.
  • Drop the Hammer: He keeps a mallet on hand to fight with in Mario & Luigi: Partners in Time.
  • Enemy Mine: He briefly teams up with Yoshi in Yoshi's Island DS to fight against his future self.
  • Establishing Character Moment: Foreshadowing their future relationship, Baby Bowser is first introduced in Partners in Time when he’s trying to kidnap Baby Princess Peach.
  • Evil Prince: Since he's just a kid, he's usually addressed as Prince Bowser. It's unknown who the current King of the Koopas is, or if there even is one.
  • Fiery Red Head: Bowser had an even worse temper as a child than he does as an adult.
  • Generation Xerox: Though he prefers brute force over his future son's more tricky approach, they look identical and share many personality traits.
  • Gold Fever: Baby Bowser loves treasure, and whenever he finds some he declares that it’s all ‘his’ and thinks anyone else getting near him wants to steal it.
  • Ground Pound: One of his primary attacks in the original Yoshi's Island and in Yoshi's New Island.
  • Hypocritical Humor: He scolds the baby Mario Bros. for stealing food after he literally just ate a bunch of cookies that he stole.
  • My Future Self and Me: He's met his older self in two separate series. The two successfully team up together in Mario & Luigi: Partners In Time, with neither of them realizing they’re the same person. In the Yoshi's Island series, his older self actually kidnaps him, causing Baby Bowser to become adult Bowser's enemy.
  • Parental Substitute: He has no known parents to speak of, and is largely raised and cared for by Kamek.
  • Royal Brat: Unlike his adult self, who is generally kind to his minions, Baby Bowser isn’t beyond stomping on them out of annoyance, insulting them, and having them slave over his every need.
  • Throw the Dog a Bone: A recurring theme is that he really wants to ride a Yoshi, which he calls a ‘Gween Donkey’, a wish that does eventually come true for him in Yoshi's Island DS.

    Bowser Jr.
"Someday, when I'm bigger... I wanna fight that Mario again!"
"Leave my Mama alone, you bad man! I won't let you take Mama Peach away!"
Voiced by: Dolores Rogers (2002–2007), Caety Sagoian (2007–present)

Bowser Jr. (known in Japan as Koopa Jr.; full name presumably Prince Bowser Koopa Jr.) is Bowser's son and heir to the throne. He's a rotten little schemer who wants Princess Peach to become his mommy. He first appeared in Super Mario Sunshine disguised as Mario in order to get him sent to prison, and when that failed he personally kidnapped Princess Peach himself, revealing his true form. Since then, Bowser Jr. has become his father's right hand man and most reliable soldier, having successfully kidnapped Princess Peach more times than anyone except Bowser himself.

Tropes associated with Bowser Jr.:

  • Affectionate Nickname: His father typically just calls him 'Jr.' or 'son'. Mario & Sonic at the London 2012 Olympic Games reveals that his minions call him 'little sire', and the 3DS Super Smash Bros. audience calls him "BJ" in their encouragement chants. Roy of the Koopalings calls him 'squirt', and both him and Paper Bowser Jr. call each other 'buddy' in Mario & Luigi: Paper Jam.
  • Art Attacker: Thanks to his Magic Paintbrush, he can create enemies out of paint.
  • The Artifact: His Magic Paintbush hasn't had any significance since the days of Sunshine and when it appears it's usually just a throwback. The Wii era introduced a replacement Iconic Item in the form of his miniaturized, heavily customizable Clown Car, but the brush still appears on occasion. Heck, during his stint as a Bonus Boss (see below), the only use he finds for it is to tickle people.
  • A Sinister Clue: He's the evil son of the evil Koopa King, and he's a leftie.
  • Attack Its Weak Point: In boss fights where he appears in the Clown Car or some other giant machine, the weak point tends to be Bowser Jr.'s cockpit. This has carried over to Super Smash Bros. for Nintendo 3DS / Wii U, where hitting Bowser Jr. will do more damage than hitting the Junior Clown Car.
  • Autobots, Rock Out!: A villainous example; with a couple of jazz exceptions, all of Bowser Jr.'s leitmotifs are either rock n' roll based or involve an electric guitar.
  • Badass Bookworm: Quite handy with machinery, just like Bowser. While admiring the ghost ship stage in Fortune Street, he casually mentions he designs his own mechas, and his Final Smash trophy in Super Smash Bros. for Wii U outright states that he's brainier than his father.
  • Badass Driver: Bowser Jr. has controlled a variety of machines throughout his villainous career and is a remarkable pilot for his age. In particular, he's so comfortable flying his Clown Car that he's frequently seen standing on its rim without fear of falling off. He's also apparently a talented horseman, as he's the main opponent in the Equestrian trial in Mario & Sonic at the 2016 Rio Olympics.
  • Badasses Wear Bandanas: One of the reasons he drew fangs on his bandana is to make himself look more intimidating when he wears it over his mouth. It could also be a nod to his piloting abilities by referencing the shark-teeth nose art found on fighter planes.
  • Bad Boss: In his Boss Battle in Super Mario Galaxy, Bowser Jr.'s ship's weaponry not only damages Mario, it kills any Mook unfortunate enough to get between the Koopa prince and his prey.
  • Bait-and-Switch Boss: His final appearance in Galaxy, which he fires meteors to try and stop Mario's ascent.
  • Barrier Warrior:
    • The Magic Paintbrush can create an orange, gelatinous wall of caustic paint that's immune to the Paintbrush's normal weakness of water, but can still be erased with Yoshi saliva.
    • In Sticker Star, he'll activate a domed barrier over his Clown Car to protect himself.
    • In the final battle of Puzzle & Dragons: Super Mario Bros. Edition, he'll cast defensive buffs to shield himself and the Bowser + Koopalings combo. On top of that, his separate life bar, light-element status, and tendency to heal soaks up a lot of damage that would normally be aimed at his father and friends.
  • Bearer of Bad News: His role in Mario Party 9, where he updates his father on the player's (successful) progress and Bowser's (failed) defenses, until the final board where he takes on Mario personally.
  • Big Bad: Of Sunshine, being the instigator of the plot, and the main threat.
  • Big Guy, Little Guy: The little guy to his father's big guy.
  • Bizarre and Improbable Ballistics: In all of his Mario Tennis appearances, he's classified as a Tricky-type character, meaning all his shots are imbued with a very high amount of curve. Inverted in his Mario Golf appearances, where his shot is classified as perfectly straight and low flying.
  • Black Bead Eyes: Just like Baby Bowser, Bowser Jr. has small, beady black eyes, although his eyes usually have a pupil-like shine to them that Baby Bowser's doesn't. Just like Bowser's red eyes didn’t become apparent until he grew up, it's unknown what Bowser Jr.'s actual eye color will be when he's older.
  • Bonus Boss: In Mario & Luigi: Dream Team.
  • Bratty Half-Pint: The premiere brat of the Mario series, Bowser Jr. loves being a headache to the people of the Mushroom kingdom.
  • Breath Weapon: Initially untrained and undeveloped at fire breath, as he attempted to do so in Mario Superstar Baseball with only a weak ember, but mastered it in New Super Mario Bros. Wii, where it homes in on the players and sets the floor ablaze on contact. While he never actually attacks with it, Dream Team shows he can now breathe an entire stream of fire.
  • Breaking the Fourth Wall: Bowser Jr. breaks the fourth wall several times through out the New Super Mario Bros. series, usually as little self aware pivots to the screen done for comedic effect. However, the most notable instance is the very last scene in the original New Super Mario Bros., where he turns to the players and snaps his jaws.
  • Brilliant, but Lazy: In the physical sense; he's clearly shown he's capable of acrobatic feats, impressive running speed, and enough physical stamina to keep ahead of Mario on foot, but he generally prefers to cruise around in his Clown Car due to laziness. This is especially evident in Mario & Sonic at the London 2012 Olympic Games, where it takes goading and encouragement from his minions to get him to begin training, but becomes very successful when he finally does start applying himself.
  • But Thou Must: In Mario Party 9, when the player lands on a Bowser Jr. space and spins for a Bowser Jr. minigame, he'll ask if you're sure you want to play the one that you end up landing on. If you say "yes", you'll play the minigame, and if you say "no", he'll still make you play that minigame.
  • Card-Carrying Villain: While he doesn't display it as frequently as his father, Bowser Jr. brags about his 'evilness' with the same kind of relish, particularly in games where he's competing against people like Fortune Street and Mario Super Sluggers.
  • The Chase: In virtually all his appearance where he plays The Dragon or the Big Bad, it will involve him leading Mario on a giant chase.
  • Cheerful Child: When he's not trying to kidnap her, Bowser Jr. tends to act this way whenever he's around Princess Peach.
  • The Chessmaster: One of the reasons he's been so successful at capturing Peach has been his ability to either neutralize or distract Mario. In his first appearance, he commits various crimes disguised as Mario in order to get him thrown into prison, and in New Super Mario Bros. he causes a diversion in the castle while Mario and Peach are out on a walk to get the two separated.
  • Color-Coded Elements: His magic brush is capable of creating Fire Graffiti and Electric Graffiti by changing the color of the paint.
  • Confusion Fu:
    • He tends to mix up his attacks to throw the Bros. off, and he shows a surprising ability to adapt to a bad situation rather quickly.
    • In New Super Mario Bros. Wii, the final battle has him pick over his Clown Car and his dad's; the latter of which was chosen.
    • During his boss fight in Dream Team, he attempts to trick the bros by throwing either a piece of junk, or a Bob-omb and then attacking the one that isn't distracted.
  • Cool Airship: Played with in the New Super Mario Bros series as he's usually guarding his father's flagship instead of having his own. Played straight with his miniature galleon in the original Super Mario Galaxy As well as his battleship in Paper Mario Sticker Star complete with Banzai Bill Blaster.
  • Cool Boat: Bowser Jr. has piloted a variety of vehicles, including submarines. In his first appearance he piloted a bullet-bill armed submarine in the final boss fight with his father. Later, his Junior Clown Car is modified with a submarine mode to attack Mario underwater in New Super Mario Bros. U.
  • Cool Car:
    • The Junior Clown Car is a miniature version of his dad's Clown Car, complete with a multitude of personal on board weapons and a face so expressive it borders liveliness.
    • In Double Dash, Bowser Jr.'s personal car is the Bullet Blaster, one of the fastest lightweight cars in the game and easily the meanest looking.
  • Crowd Chant: He, like the other fighters, has an audience cheer in Super Smash Bros. when a someone playing as him does particularly well. They don't call out his entire name, but simply shorten it to "BJ" in the 3DS version and "Jr." in the Wii U version.
  • Cryptic Background Reference:
    • At the end of Super Mario Sunshine, the only clue we get to whoever his mother may be is that he knew it wasn't Peach from the very start. He never states whether this means he discovered who his actual mother is or not, and he doesn't seem to press the matter any further with his dad (who seems extremely happy to avoid talking about it any further). He continues to call Peach 'Mama' in later appearances despite knowing full well she isn't.
    • He states that "a strange man in a white coat" gave him his Magic Paintbrush in Sunshine. It is very heavily implied that the old man in question is professor E. Gadd, but what actually happened between the two and what relationship they have, if any, has never been followed up on.
  • Cute Little Fang: His handkerchief sports these as well as the little fang he has in his mouth.
  • Defeat Means Playable: In Puzzle & Dragons: Super Mario Bros. Edition, just like the Koopalings, he will join your team if you beat him in the final Star World Tower.
  • Doomsday Device: Invoked with his "Boomsday Machine" in Super Mario Galaxy 2.
  • The Dragon: In most of his appearances, Bowser Jr. has been his papa's main backup. Sometimes, he and Kamek work together as Co-Dragons.
  • Dragon Ascendant: Presumably, Bowser Jr. temporarily becomes the leader of the Koopa Troop while his father is a member of the undead in New Super Mario Bros.
  • The Dreaded: To Toads; since Bowser Jr. spends so much time infiltrating the Mushroom Kingdom, Toads seem to fear him just as much as they do Bowser. This is later justified when he stuffs Toads into containers for sheer amusement in New Super Mario Bros. Wii.
  • Drop the Hammer: Bowser Jr., like many in the Mario games, seems to particularly favor them; he’s built at least two giant mechs that use them to attack people, not counting his Junior Clown Car in Super Smash Bros. for Nintendo 3DS / Wii U which has two wrecking balls, a giant nail hammer, and a squeaky mallet. In Super Mario Maker, if equipped with a pair of wings, he'll start to literally hurl hammers at Mario if he comes near.
  • Dual Boss:
    • Bowser Jr. frequently battles alongside his father in final boss fights, usually as small but fast supporting fighter. He does this in Sunshine, New Super Mario Bros., and New Super Mario Bros. U.
    • In Puzzle & Dragons: Super Mario Bros. Edition, Bowser Jr. is a separate entity from the Bowser + Koopaling combo, with his own life bar and attacks. His HP is comparatively the smaller of the two, but his light-element status perfectly complements the combo’s dark-element status by covering each-other’s vulnerabilities, and Bowser Jr. casts defensive buffs and healing spells to effectively double the amount of damage the player needs to dish out to win. Finally, if Bowser Jr. is defeated, the combo will sometimes use a revival spell to bring him back to full health.
    • He's also this with his paper counterpart in Mario & Luigi: Paper Jam where the duo will work together using attacks and even healing/reviving each other.
  • Dub Name Change: For most of the world his name is either Bowser Jr. or Koopa Jr., with the exception of European Spanish translations, where he's called 'Bowsy'.
  • Easily Forgiven: He never does seem angry at his father for lying to him about who his mother is. Instead, he just seems fixated on the idea of fighting Mario again.
  • Enfant Terrible: He's the son of an Evil Overlord who aspires to be like his dad.
  • Establishing Character Moment: He first appears on a giant mech claiming that he's there to rescue 'mama' Peach from Mario.
  • Everything's Squishier with Cephalopods: He commands two different Giant Squid monsters in the series: Gooper Blooper in Sunshine, and King Caliente in Galaxy.
  • Even Bad Men Love Their Mamas: Played With. Bowser Jr. has shown time and again that he’s fond of Princess Peach, regardless of whether she’s his biological mother or not. Aside from encouraging her to partake in vacation activities with him in Sunshine, she’s the only character other than Bowser that Jr. speaks nicely to in Mario Sluggers, his mechanical claw gingerly moves her out of harms way in the opening of New Super Mario Bros. Wii U, and in Fortune Street he admits that he doesn't mind spending a little extra money at a shop (within reason) as long as it’s hers. And yet, he still has no reservations about kidnapping her time and again.
  • Even Evil Has Loved Ones: No one in the entire world is more important to him than his father— to Bowser Jr., Bowser is the best and strongest at everything, and he'll get angry at the mere suggestion to the contrary. He also seems to have an intense emotional bond with Princess Peach, and wants her to be his mother just as much as Bowser wants her to be his wife. He even revives his own dad in New Super Mario Bros.
  • The Evil Prince: The heir to his father's throne.
  • Evil Redhead: Just like his dad.
  • Fiery Red Head: While not to the same degree as Bowser, Bowser Jr. has definitely inherited at least some of his father's bad temper, as well as his fiery red hair.
  • Final Boss: While he never plays this role by himself, he often shares it with his dad. This is the case with Super Mario Sunshine, New Super Mario Bros., and New Super Mario Bros. U.
  • Forgotten Phlebotinum: Despite its immense potential for destruction, Bowser Jr. never again uses the Magic Paintbrush in any of his evil schemes after Sunshine, except for a minor Continuity Cameo in his bonus boss fight in Dream Team, where he uses it for tickling people, and his Final Smash in Super Smash Bros. He does often use it for sports, though.
    • He also never again uses a magical disguise on par with his Shadow Mario bandana.
  • Fragile Speedster: Typically as fast and agile as the Mario Brothers, but without the staying power to back it up. This shows in his boss battles (when he isn't piloting some sort of robot), and his stats in the spin-off games. For example, in Mario Kart: Double Dash!!, Bowser Jr.'s personal kart is the fastest but also the lightest and easiest to knock around; and he's classified as a Speedy character in Mario Sports Mix.
  • Full-Body Disguise: The Shadow Mario disguise completely alters Bowser Jr.'s body shape and color tone to the point that it'd be impossible for someone to guess it was him if they didn't know about the disguise beforehand.
  • Gadgeteer Genius: One of Bowser Jr.'s major calling cards is his affinity for machines, and is the most extensive gadget user in the Mario universe next to Professor E. Gadd. This generally includes things like mechs, vehicles, and robots to use in his battles against Mario, some of which he apparently designs himself. However, the spin-offs show he’s also attracted to less sinister tech as well, like slot and pinball machines.
  • The Gambler:
    • A rather bizarre but noticeable tendency in some spin offs have been to give him a casino bent, such as the slot-machine stage gimmicks in 3-on-3 and Sports Mix, as well as his dice based boss fight in Mario Party 9. These instances tend to also come with casino-style big band jazz.
    • A figurine description in Mario Party DS suggests he might be a gambler himself.
  • Generation Xerox: Bowser Jr.'s appearance is pretty much identical to his father when he was a kid, and they share many personality traits. Bowser Jr. does seem more competent of a villain than Bowser was at his age.
  • Genius Bruiser: You know the Jumping Out of a Cake method of capturing Princess Peach in New Super Mario Bros. Wii? Well, according to the Japanese site, that was planned by Bowser Jr. His debut scheme in Mario Sunshine is one of the most complex evil schemes in the series.
  • Giant Space Flea from Nowhere: In Dream Team.
  • Giggling Villain: He giggles a lot when not imitating his dad's Evil Laugh.
  • Glass Cannon: In Super Mario Maker, Bowser Jr., unlike his father, can actually be defeated by jumping on his head enough times. To compensate for his lack of defense, his fireballs are better aimed and he has a unique shell spin move to attack over a wide area.
  • Glory Seeker: Particularly, glory in the eyes of his dad, which he craves to a fault. In Mario & Sonic at the London 2012 Olympic Games, it's shown he can be made to do nearly anything by simply telling him ‘I bet your father would be really impressed’. In fact, this works so well that at one point he bets his freedom on a race with Metal Sonic just because a minion suggested that his father would be impressed if he won.
  • Go-Karting with Bowser: In the Mario Kart series he goes karting with the other characters. Guess who his default driving partner is in Double Dash?
  • Gotta Catch 'Em All: In Sticker Star his main objective seems to be hunting down rare stickers. At least until the last time he's encountered, during which he wants revenge.
  • Green-Eyed Monster: His villainous acts in Mario Super Sluggers stems from intense jealousy that Mario and friends have their own baseball island to play on.
  • Hammer Space: In Paper Jam, it's shown he stores various thing under his bandana, somehow.
  • Happy Dance: Bowser Jr. often does a little hop from one foot to the other when he's excited or energized. In Mario & Sonic at the Winter Olympics, his father has to motion for him to keep still when he does this during the opening ceremony.
  • Healing Factor:
    • Through out his boss battles in Sticker Star, he'll start to heal himself once his health gets too low.
    • In the final boss fight of Puzzle & Dragons: Mario Edition, he'll often heal both himself and the Bowser + Koopalings combo whenever he or they have low HP on his turn.
    • In their boss battle Mario & Luigi: Paper Jam, both Juniors may pull out a Mushroom or even a one-up Mushroom out of their clown car to heal their buddy.
  • The Heavy:
    • In Sunshine. His dad is the Final Boss, but Bowser Jr. does all the work.
    • This is generally his role in plots where he's involved, and takes up this role again in every New Super Mario Bros. game except for 2, which he wasn't present in.
  • Hero Stole My Bike: As the Junior Clown Car appears in more games, it's becoming more frequent for Mario to hijack it, often to use it against Junior or even Bowser himself.
  • Heroic Wannabe: He's explicitly stated to have fantasies about being a hero in Mario Party: Island Tour, and in his original appearance he claimed he was rescuing princess Peach from the 'bad man' Mario. Finally, in Mario & Sonic at the London 2012 Olympic Games, he gladly takes credit for accidentally saving two chaos from Dr. Eggman's robots, with the chapter in question even being named 'Bowser Jr.: Superhero?'
  • Hero Worship: Inverted. Bowser Jr. adores his evil father and even states once that his dad is "braver than any dumb hero". That said, in Mario Party: Island Tour his father does mention that Bowser Jr. often fantasizes about playing the hero himself.
  • Humongous Mecha: One of his favorite and most well known tactics, Bowser Jr. has used a variety of giant robots and mechs in his boss fights, among them being Mecha-Bowser, Megaleg, Megahammer, and the Boomsday Machine. He also has a stage in Super Mario Galaxy named Bowser Jr.'s Robot Reactor.
  • Hyperspace Arsenal: His Junior Clown Car, appropriately enough, seems to have unlimited item space for bombs, Mechakoopas, and other weapons.
  • Iconic Item: His bandanna and Magic Paintbrush; even after Sunshine, Bowser Jr. was so keen on the bandanna that he got a new one. Nowadays, the Koopa Clown Car has also become this, nearly displacing the Paintbrush, to the point that he even plays tennis with it.
  • Identical Grandson: Bowser Jr. looks quite similar to Bowser when he was young. There are consistent differences in the shape and proportion of their nose, ponytails, and eyebrows, but these are fairly subtle. The only major differences seems to be that Bowser Jr.'s bandana typically has drawn on fangs as opposed to the white bandana Baby Bowser favors, if he even wears one at all.
  • I Have the High Ground: He seems to enjoy being in high places. Aside from flying around in his Clown Car, he's commonly seen hanging out on the bowsprits of ships or towering in one of his mechs. He lampshades this himself in Mario & Luigi: Paper Jam.
  • I Just Want to Have Friends: In Mario & Luigi: Paper Jam it's heavily implied that he's much lonelier than he cares to admit. When he finally finds a friend in Paper Bowser Junior, he worries so much about losing him that the two try to hunt down the only way back to the paper world and destroy it.
  • Improbable Power Discrepancy: In his Bonus Boss battle in Dream Team, he is somehow a more powerful boss than his own dad after absorbing the Dream Stone and becoming a Reality Warper.
  • Improbable Weapon User: The Magic Paintbrush and the Junior Clown Car. Manages to play it straight and invert it simultaneously in Mario Super Sluggers by using the Magic Paintbrush as a baseball bat. (In Mario Superstar Baseball, he just had a spiky, metallic bat, instead.)
  • Interpretative Character: Again, in the physical sense. His Competitive Balance status between spin-offs varies wildly between titles: he's balanced in Mario & Sonic Olympics, offensive in Sluggers and Strikers, speedy in 3-on-3 and Sports Mix, technical in Mario Golf, tricky in Mario Tennis, and a Lightning Bruiser in Smash Bros.
  • Intimidation Demonstration: He attempts this in his away-team introduction in Mario Strikers: Charged, but (rather adorably) falls short.
  • Jack-of-All-Stats: In the Mario & Sonic Olympics series, he's classified as a Balanced-type character.
  • Jazz
    • Going along with his frequent gambling themes, a lot of his spin-off music is dark, casino-style jazz, such as in Mario Party 9, Mario Hoops 3-on-3, and Mario Sports Mix.
    • In Super Mario Maker, every in-game object plays a different instrument when they hit a music block; the instrument that plays for Bowser Jr. is, naturally, the saxophone.
  • Jumping Out of a Cake: Along with the Koopalings in New Super Mario Bros. Wii.
  • Junior Counterpart: To his father.
  • Kid-Appeal Character: He's a villainous character for sure, but he's also cute and child-like enough to be appealing to children.
  • King of Games: Bowser Jr. brags that he's a pro at pinball in Mario Party DS, to the extent that his father is perfectly fine with letting him run the pinball stage in story mode. However, since this is a stage and not an actual pinball game, we never actually see if he is as good as he says he is. That said, the collectible descriptions imply that he is more strategic than his father.
  • Leitmotif: Has one in the Super Mario Galaxy series, as well as Mario Party 9, which was remastered for Mario Party 10 and ''Paper Mario: Sticker Star.
  • Le Parkour: In his first appearance, Jr. proved himself to be fairly acrobatic while disguised as Shadow Mario, able to keep just out of reach of Mario in the city streets of Isle Delfino.
  • Lightning Bruiser: In Super Smash Bros. He's tied with Charizard for the fourth heaviest character in the game, racks up damage quickly, takes less damage when the Clown Car is hit instead of Jr. directly, and is decently fast for a character of his weight class.
  • Like Father, Like Son: Not only does he look just like his papa, but they share the same goal: kidnap Peach and crush Mario. Their motivations, however, seem different. For Bowser, defeating Mario is a personal matter, while Bowser Jr. sees defeating Mario as something that would make his dad proud.
  • Luke, You Are My Father: Bowser Jr. declares that Peach is his mother, an idea that he got from his father. While this is a lie, Bowser Jr. knew all along that Peach wasn't his mother, but still wanted to kidnap her because he wishes she might act like his mother.
  • Magic Versus Science: On the opposite end of the scale from his father: while Bowser's been more frequently seen using magic, Bowser Jr. has more frequently been shown to use machines. This is perhaps best exemplified in that Bowser and Koopalings have all been shown using magic wands at some point in their lives, while the closest equivalent that Bowser Jr.'s ever used is the Magic Paintbrush, which is one of E. Gadd's inventions.
  • Magitek: The Magic Paintbrush uses E. Gadd's technology to create magical paint.
  • Make Me Wanna Shout: His Sonic Roar in Mario Strikers Charged.
  • Megaton Punch:
    • In New Super Mario Bros. U it was first revealed that Bowser Jr. had a pair of boxing glove arms installed on his Clown Car. It's since become a staple weapon of the vehicle, appearing in several of his attacks in Super Smash Bros. for Nintendo 3DS / Wii U as well as in Mario Party 10 as a Bowser Jr. Space penalty.
    • Bowser Jr. is the one who controls the giant mechanical claw that grabs Princess Peach at the beginning of New Super Mario Bros. U, and uses it two more times through out the game in an attempt to squash Mario.
  • Mentors: He's the host/guide for Bowser in Mario Party 10's Bowser Party and Bowser Challenge mode.
  • Mighty Glacier: In both the Mario Sluggers and Mario Strikers series, he's a high-offense character with low speed.
  • Missing Mom: He acknowledges that Peach is not his mother at the end of Super Mario Sunshine, yet does not pursue the issue any further than that. He still refers to her as "Mama Peach" in Mario Superstar Baseball, implying he wishes she could become his stepmother. During the promotion of Super Mario Maker, however, Shigeru Miyamoto jokingly suggested that he is Bowser Jr.'s mother.
  • Modest Royalty: Just like his dad, he doesn't wear anything to suggest he's a prince.
  • Morality Pet:
    • Bowser Jr. is one to Bowser. While it's hinted he may not always be a very responsible father, Bowser clearly loves his boy very much, and constantly tells him how proud he is of him. Some of Bowser's most sympathetic moments have been while interacting with his son.
    • Bowser is also one to Bowser Jr. He may act like an arrogant, selfish, destructive brat around most people, but when interacting with his dad he's an obedient, enthusiastic, and very loving son.
  • More Dakka: Of the enemies seen assisting Bowser Jr., the two he seems to favor the most are Bullet Bills and Bob-ombs. His Junior Clown Car in Super Smash Bros. for Nintendo 3DS / Wii U also comes equipped with a massive cannon. Also his airship in Paper Mario Sticker Star, in addition to the usual cannons, has a Banzai Bill cannon instead of a face on the front.
  • Muck Monster: The goop produced by the Magic Paintbrush spawns small sludge monsters that will attack Mario if he gets too close.
  • Never My Fault: A trait he shares with his dad. While he's never blamed his minions or his machines for his failures, he has blamed Mario and friends for 'picking on him' in response to his shenanigans in the Mushroom Kingdom. He also refuses to believe Mario keeps getting the best of him fairly in Sunshine, and tells him he's only able to get as far as he does because of FLUDD.
  • Nice Job Fixing It, Villain: A super-sized Bowser would have won in New Super Mario Bros. U if only his son hadn't tried to help out by bringing Bob-ombs and an unshielded clown car for Mario to use as weapons. Even Junior himself can be picked up and thrown into his giant daddy, so his presence isn't really helping Bowser at all.
  • Ninja Brat: His preferred method of getting at Peach isn't to storm the castle barricades, but to sneak in and then grab her at the right opportunity, usually with his bandana drawn up to cover his face. It helps that he's a lot smaller and faster than his dad.
  • Non-Mammalian Hair: A turtle with red hair tied in a ponytail. Like father, like son.
  • Not Now, Kiddo: Mario & Luigi: Paper Jam implies that Junior gets this whenever he isn't taking part in his father's schemes.
  • Overlord Jr.: He's Bowser's son and the Prince of the Koopas.
  • Overnight Age-Up: Jr.'s debut in Galaxy features one very prominent change — he's as tall as Peach now, implying a Time Skip since the Gamecube era. Mario Kart Wii ratifies it, casting him as a medium weight racer rather than his original lightweight designation.
  • Parental Substitute: Toyed with; although it's clear at the end of Sunshine that Bowser Jr. understands Peach isn't his real mother, he seems to desperately wish that she would play some kind of motherly role in his life. Peach herself does not see their relationship as this; however, in Fortune Street she often criticizes the way Bowser is raising him, hinting that she at least cares somewhat about his wellbeing.
  • Person of Mass Destruction: In Super Mario Sunshine, he manages to cause considerable collateral damage to Isle Delfino's infrastructure, ecosystem, and way of life... with nothing but a magic paintbrush.
  • Poisoned Weapon: The paint that the Magic Brush produces is highly toxic, and can be imbued with caustic or elemental properties that will damage Mario on contact.
  • Portal Door: One of the Magic Paintbrush's abilities is the power to create 'color portals' out of the Shadow Mario's stylized M insignia.
  • Reality Warper: The power of the magic brush isn’t in its ability to be used as a direct weapon, but in its ability to create allies, warp landscapes, alter the properties of objects, and create elemental energy. If fact, if it weren't for it’s Weak Sauce Weakness of pressurized water, it might just be the most powerful piece of technology yet shown in the Mario universe.
  • Reclining Reigner: He strikes this pose after his break-dancing home entrance in Strikers: Charged and if he gets second or third place in Mario Party: Island Tour, probably to look cool and aloof.
  • Recurring Boss: In most appearances, though his tactics usually change considerably.
  • Red Oni, Blue Oni: He the red to Kamek's blue.
  • The Reveal: It's at the end of the fight with Mecha-Bowser in Mario Sunshine that Bowser Jr., in his first ever appearance, reveals he was Shadow Mario all along, and had been masquerading as Mario to get him framed for the crimes he committed so he'd be thrown in jail.
  • Rich Boredom: It’s hinted several times that, underneath it all, Junior wants to have fun just like any other normal child would. After he and his father are soundly beaten in Mario Super Sluggers, Junior persuades his father to accept an invitation to a party that Bowser was less than keen on attending. In Paper Jam, he states that he was incredibly bored before Paper Bowser Jr. shows up and almost immediately asks if he’ll play with him.
  • Riddle for the Ages: Who is Bowser Jr.'s biological mother? Does he himself know? If not, why hasn't his father told him? Or, when one remembers that babies in the Mario world are delivired by storks, does he even have a biological mother?
  • Royal Brat: Surprisingly inverted. Taking after his dad, the few times Bowser Jr. has been seen conversing with his minions shows him treating them rather well. Although, he does get annoyed at them if they keep reminding him about his size.
  • Scarf of Asskicking: Had one since his debut in Sunshine. It was part of a disguise in that game, but nowadays it's just something he wears.
  • Screw This, I'm Outta Here!: After watching his super-sized father's melodramatic defeat at the hands of Mario in New Super Mario Bros. U, Bowser Jr. decides to simply give up and jump into the ravine along with him.
  • Secret Identity: Of Shadow Mario... in Sunshine at least. The identity of Shadow Mario whenever the two go golfing is less clear.
  • Sentient Vehicle: While Bowser's Koopa Clown Car has emoted as well, the Junior Clown Car has been so expressive that it's beginning to be implied that it may have some degree of sentience. This is further backed in Super Mario Bros. for Nintendo 3DS / Wii U when the Koopalings all have mass-production model Clown Cars with robotic eyes while his has more organic eyes.
  • Sky Pirate: Whether in airships or his own cannon-armed personal Junior Clown Car, Bowser Jr. has often taken this role as his villainous motif. The bandana enhances the effect.
  • Smug Smiler: Very rarely is he ever seen without a self-confident little smirk on his face.
  • Sore Loser: Perhaps even more so than his hot-headed father, Bowser Jr. is a very sore loser. He has never been seen congratulating anyone for beating him (except his father and occasionally Princess Peach in spin-offs), and usually accuses the other party of cheating, being overly aggressive, or winning solely through luck. He also tends to hold grudges against those who consistently beat him until winning against them takes a higher priority than the task at hand—a trait that has made Mario his arch enemy since his original Sunshine appearance.
  • The Southpaw: Bowser Jr. is traditionally left-handed, a trait he shares with other Miyamoto creations such as Link. Most sports games show him using his left hand dominantly, and in New Super Mario Bros. U the robotic claw he uses is a left hand.
  • Spikes of Villainy: Just like his dad, he sports a shell with spikes on it, although they aren't as pointy as his father's.
  • Spin Attack: His special attack in Puzzle & Dragons: Super Mario Bros Edition, "Junior Smash" has him ram his spinning clown car into the party. He also can use his shell to spin about like Bowser and The Koopalings, although he rarely does it outside of Super Mario Maker.
  • Spoiled Brat: His father spoils him rotten by giving him all the toys and gadgets he could want. That being said, he genuinely enjoys just being with his dad and causing trouble with him.
    • Mario & Luigi: Paper Jam implies that Bowser does this partially to get Junior to do something he doesn't want to do.
  • Storming the Castle: Bowser Jr. ironically has one thing in common with Mario: they're both very good at infiltrating enemy castles. Of course, Mario typically infiltrates Bowser's castle to rescue Princess Peach, while Bowser Jr. infiltrates Mushroom Castle to kidnap her.
  • Street Urchin: His original appearance in Sunshine and some character ornamentations in the spin off games tend to give him an urban hoodlum slant. His painted bandana, love of graffiti, and street-themed sports arenas are among these.
  • Suddenly Voiced: Inverted. In Sunshine, Bowser Jr. for some reason actually spoke like everyone else in the game, but from Galaxy onwards, he reverted to dialogue boxes and Voice Grunting like everyone else.
  • Surf Rock: His entrance and victory fanfare in Mario Strikers: Charged.
  • Suspiciously Similar Substitute: His design is incredibly similar to Baby Bowser in Yoshi's Island, retroactively becoming nearly identical.
  • Swiss Army Weapon: In Super Smash Bros. for Nintendo 3DS / Wii U, his signature Junior Clown Car comes equipped with drills, boxing gloves, Mechakoopas, a go-kart form, a tongue, a cannon, buzz saws, wrecking balls, mechanical claws, a giant fork, a self destruct mechanism, and a bladed propeller.
  • Thememobile:
  • Thicker Than Water: Because of Bowser's "death" in New Super Mario Bros., Bowser Jr. would technically take the throne, if just for a short while. In the end, however, he's more concerned with getting his dad back, and revives Bowser with a magic potion.
  • The Trickster: Bowser Jr. favors tricks and sneakiness as opposed to his father’s more physical approach. This seems to be one of the ways he fundamentally differs from his father, as every depiction of Bowser as a child shows he preferred a more physical attack pattern even when he was Jr.'s age.
  • Turtle Power: Again, son of the Koopa King.
  • Undying Loyalty: Bowser Jr. deeply loves his father, and as shown in New Super Mario Bros., remains loyal to him even after his apparent death.
  • Unexpected Character: OK, under normal circumstances, he would never be unexpected. However, being the Bonus Boss of Dream Team came right out of nowhere, with no foreshadowing whatsoever and having never being mentioned beforehand.
  • The Unreveal: During a Mario Myths video of Super Mario Maker, Shigeru Miyamoto finally answers who Jr.'s mother is... by pointing at himself.
  • Vehicular Turnabout: You can hijack the Junior Clown Car in New Super Mario Bros. U, and can use it against him and Bowser. In Dream Team you can jump into his Clown Car whenever he gets out and chase him down, throwing various kinds of junk at him for damage. As this is the only chase sequence in the game where it's YOU chasing down the boss, who has to avoid YOUR attacks this time, it's immensely satisfying.
  • Video Game Stealing: In his secret boss fight in Dream Team, every time he's hit with a Bro attack, he'll jump out of his car and steal the bro item away. The items can be gotten back by either damaging him enough, jumping into his Clown Car while he's out of it, or winning the match.
  • Villainous Breakdown: Played both straight and inverted. Junior sometimes begins showing visible cartoon fuming when he's on the brink of defeat. In New Super Mario Bros. U, he loses his temper just seeing Mario enter his room. However, in defeat he's usually one to throw in the towel and even lead a retreat, especially if his Dad goes One-Winged Angel and is still defeated.
  • Villainous Friendship: In Mario & Luigi: Paper Jam, Bowser Jr. and Paper Bowser Jr. form a friendship so ironclad that it borders on Heterosexual Life-Partners territory. The two love each other's company and quickly become fearful that, should the Paper World book be discovered, Paper Bowser Jr. would have to leave and the two would be bored and lonely again.
  • Weaponized Car: Even more so than the original Koopa Clown Car, his Junior Clown Car is armed to the teeth with a large variety of weapons and transformations.
  • "Well Done, Son!" Guy:
    • One of his most defining characteristics is his intense desire to make his father proud of him, and he'll go to absolutely tremendous lengths to do so. It's played with, though, in that Bowser is already extremely proud of his son— Bowser Jr. just wants to keep making him proud.
    • In the 3DS version of Mario & Sonic at the London 2012 Olympic Games, Bowser Jr. challenged Metal Sonic to a race, on the condition that if Bowser Jr. lost, he'd become Dr. Eggman's slave. What did Bowser Jr. want if he won? Only for Eggman to tell his dad about how awesome he was.
  • What a Drag: It's often Bowser Jr.'s job to drag his dad back home after getting pummeled by Mario. In New Super Mario Bros. U, it went one step further when he ended up having to fly his father AND the seven Koopalings home in his tiny and very overworked looking Clown Car.
  • Your Size May Vary: Just like Bowser, his size tends to vary from game to game. In some games like Super Mario Sunshine, he's roughly the same size as Mario. In other games like Super Mario Galaxy, he's taller than Peach.

    The Koopalings
"We just love being mean!"

A name given to seven siblings who appeared as bosses in Super Mario Bros. 3, Super Mario World, Mario is Missing!, Yoshi's Safari, Hotel Mario, Mario & Luigi: Superstar Saga, New Super Mario Bros. Wii, New Super Mario Bros. 2, New Super Mario Bros. U, and Mario & Luigi: Paper Jam. They have been considered Bowser's own children as late as Super Smash Bros. Melee, but they are currently only referred to as his minions outside of re-releases of older titles.

The Koopalings in general:

  • A Day in the Limelight: They were the stars of the comic story Bowser Knows Best (incidentally the only full story in the Nintendo Comics System to feature all the Koopalings), where they kidnap the Princess as a father's day gift for Bowser. Wendy and Lemmy both made additional appearances in the comics and got their own Day In The Limelight, Wendy in the story Fins and Roses (which could also count as Villain Episode), and Lemmy (sort of) in the story The Revenge of Pipe Ooze!
  • Big Screwed-Up Family: For the first time in years, their Palutena's Guidance description in Super Smash Bros. for Wii U acknowledges the ambiguous relationship to Bowser and Bowser Jr., suggesting they may actually be more like estranged relatives.
  • Canon Foreigner: Not them, but their personalities from the Mario cartoons.
  • Child Soldiers: Now that they're no longer called Bowser's children in new material, it is implied that the Koopalings are treated the same way as soldiers in his army.
  • Color-Coded for Your Convenience: The first appearances of the Koopalings had different colors in each game, until their revival in New Super Mario Bros. Wii where they got their definitive color schemes.
    • Larry - Azure/Yellow
    • Roy - Fuschia/Pink
    • Lemmy - Orange/Teal (with Yellow bouncy balls)
    • Wendy - Pink/White
    • Iggy - Lime Green
    • Morton - Black/Grey
    • Ludwig - Dark Blue
  • Cool Airship: In their debut, the Koopalings each had airships which the Mario Bros had to invade to confront them. New Super Mario Bros U and Puzzle and Dragons: Super Mario Bros edition give them new airships modeled after Bowser's Flagship.
  • Defeat Means Playable: In Puzzle & Dragons: Super Mario Bros. Edition, each Koopaling you defeat in a Special World will join your team.
  • Dummied Out: They were planned to be in Super Princess Peach, but were left out of the final game.
  • Eighth Ranger: Bowser Jr. was actually briefly considered one of the Koopalings in certain official materials of New Super Mario Bros. Wii, which evidently predated the newer mandate to separate their siblinghood.
  • Faceship: Each of the Koopalings get their own airship with their face on it in New Super Mario Bros. U.
  • Four-Temperament Ensemble:
    • Larry - Choleric/Phlegmatic
    • Roy - Phlegmatic
    • Lemmy and Iggy - Sanguine
    • Wendy - Choleric
    • Morton - Leukine
    • Ludwig - Melancholic
  • Go-Karting with Bowser: In Mario Kart 8 the Koopalings go karting with the other characters. Four of them also appear in the Mario & Sonic at the Olympic Games series.
  • Humongous Mecha: They all utilize one in their boss fights in Yoshi's Safari (although Wendy's was more of a giant shield).
  • Jumping Out of a Cake: Along with Bowser Jr. in New Super Mario Bros. Wii.
  • Magic Wand: In Super Mario Bros. 3, the Koopalings obtained the enchanted scepters of various kings and wielded them in battle, but lost them upon defeat. After spending Super Mario World without, the re-designed Koopalings appear to have obtained wands of their own and are almost never seen without them.
  • Massive Numbered Siblings: Earlier games, cartoon series, and comics depict them as Bowser's children. Shigeru Miyamoto and Takashi Tezuka no longer consider them his children, so they're no longer referred to as such and appear to be just particularly high ranking underlings of his. The Koopalings are still related to each other, though.
  • No-One Could Survive That: In Super Mario World, all of the Koopalings were either dunked into hot lava or (in the case of Morton, Ludwig, and Roy) smashed to smithereens, and then had their castle blown up for good measure. It's especially notable in that the narration in Super Mario World could be interpreted to imply that they had died in the battle, yet they managed to reappear in future titles (then again, this is basically common for the Koopa Troop).
  • Non-Mammalian Hair: Only Roy and Wendy are entirely devoid of hair.
  • Power Glows: The spells fired from their wands in New Super Mario Bros. Wii have their own colors, depending on who's using it.
  • Promoted to Playable: Mario Kart 8 marks the first time in the franchise's history where they are playable characters.
  • The Red Baron: During their showcase in the Mario Kart 8 Direct, they each have a cool title.
    • Larry is the "Super Trooper of Bowser's Army" and "Authority of Acceleration".
    • Roy is the "Runaway Heavyweight Koopa" and "Bespectacled Brute".
    • Iggy is the "Trickster with the Sweet Specs" and "Wild Child".
    • Lemmy is "Mr. Agility Supreme" and the "Ace of Speed"
    • Morton is the "Invincible Tough Guy" and "Mass of Muscle".
    • Wendy is the "Princess of Destruction" and "Speed Queen".
    • Ludwig is the "Showy Anti-Villain" and "Conductor of Chaos".
  • Retcon: They were originally stated to be Bowser's seven children (which, contrary to popular belief, was true since day one in Japan); however, Bowser Jr. was later treated as Bowser's only child, which Shigeru Miyamoto eventually stated was the case. In Super Smash Bros. for Wii U, their relationship to Bowser was vaguely described as "a real mystery," leaving the connection ambiguous.
  • Shout-Out Theme Naming: The Koopalings are either named after musicians (mostly rock and punk), or (in Morton's case) talk show hosts. note  Ludwig is the notable exception.
  • Sibling Team: Though their parentage is currently unclear, they're all siblings.
  • Spin Attack: Utilized by a few of them in Mario & Luigi: Superstar Saga.
  • Suddenly Voiced: Mario & Luigi: Paper Jam is the first time they've been given dialogue.
  • Timed Mission: The later Koopalings in Superstar Saga are accompanied by the Time Bob-omb, which counts down as the battle wears on. If it reaches zero, it explodes and instantly beats Mario and Luigi.
  • Undying Loyalty: The Koopalings were shown to be extremely devoted to Bowser. For example, in The Stinger for New Super Mario Bros. Wii, the Koopalings attempted to help Bowser up (although they ended up squished by Bowser's castle in the process), and in New Super Mario Bros. 2, they even directly aided him in a manner similar to Kamek in the former game (ie, by causing Bowser to grow bigger) during the final battle.
  • The Voiceless: Until Mario & Luigi: Paper Jam, the only time they've spoken in the games is in the original PC version of Mario is Missing! (not counting the original Super Mario Bros. 3 manual).

Larry Koopa
Voiced by: Masaharu Sato (original video animations), James Ransken (The Adventures of Super Mario Bros. 3 and Super Mario World), Lani Minella (2009-2014), Michelle Hippe (2014-present)

Larry Koopa is the runt of the litter, with a penchant for sports (at which he cheats, natch). Named "Cheatsy" in the DiC adaptations.

Morton Koopa Jr.
Voiced by: Miyako Endo (original video animations), Dan Hennessey (The Adventures of Super Mario Bros. 3 and Super Mario World), Lani Minella (2009-present)

Morton Koopa Jr. is a cantankerous little (or rather huge size-wise) grouch who takes after Roy. Named "Big Mouth" in the DiC adaptations.

  • Ambiguously Brown: Most of them look somewhat like Bowser, except Morton, who is randomly dark brown.
  • Bald of Evil: Morton would qualify (like Roy and Wendy), were it not for the three thin hairs on his head.
  • The Brute: Morton is the largest and physically strongest Koopalings (with Roy in close second).
  • Charlie Brown Baldness: With literally three hairs, Morton is technically not bald.
  • Dub Name Change: That and Theme Naming is why Morton is a Jr.
  • Dumb Muscle: His trophy in Super Smash Bros. for Nintendo 3DS / Wii U describes him as being "more brawn than brains".
  • Guttural Growler: In the New Super Mario Bros. series, he sounds like a deeper Tazmanian Devil. In Mario Kart 8, his voice now sounds like a combination between Fat Albert and Arnold Scwarzanegger.
  • I Have No Son: Someone wrote in to Nintendo Power, at the time published directly by Nintendo, and asked them what the deal was with Morton being a Jr. NP said that the Bowsers were in the middle of a family spat, and when asked about it, Bowser shouted that he had no son and threw Bob-Ombs at the writers until they ran away.
  • Motor Mouth: His cartoon version was aptly named "Big Mouth".
  • Only Sane Man: He shows shades of this in Mario & Luigi: Paper Jam. Keep in mind, that's supposed to the dumb one of the group.
    Morton: Um... So it's down to just us...
    Iggy: Pfft. No problem!
    Lemmy: Yeah, let me at 'em!
    Morton: You... you did just see what they did to everyone else, right?
  • Speech Impediment: The cartoon version of Morton tended to roll his B's.
  • Younger Than They Look: Morton's one of the biggest (THE biggest in New Super Mario Bros. Wii) Koopalings, is heavy enough to cause small earthquakes, and has a pretty deep voice. Naturally, he was implied in an early player's guide to be the second youngest after Larry.

Wendy O. Koopa
Voiced by: Miyako Endo (original video animations), Tabitha St. Germain (The Adventures of Super Mario Bros. 3 and Super Mario World), Lani Minella (2009-2014), Ashley Flannagan (2014-present)

Wendy O. Koopa is the only girl and a spoiled, greedy little brat. Named "Kootie Pie" in the DiC adaptations.

Iggy Koopa
Voiced by: Masaharu Sato (original video animations), Tara Strong (The Adventures of Super Mario Bros. 3 and Super Mario World), Mike Vaughn (2009-present)

Iggy Koopa is a technological genius who is more than a little nutty. Named "Hop" in the DiC adaptations.

  • Ax-Crazy: He was implied to be this in the text box after beating him in Super Mario World, and confirmed in New Super Mario Bros. Wii.
  • Creepy Twins: Iggy and Lemmy, especially in the cartoons. Distancing them from this trope may have been the reason Iggy was so radically redesigned compared to the others.
  • Dangerously Genre Savvy: Iggy uses Warp Pipes to good effect in his battle in New Super Mario Bros. U.
  • Divergent Character Evolution: Iggy and Lemmy were originally close enough in looks to be made twins in the spinoff cartoons, the main differences being the eyes (Iggy wears glasses and Lemmy has a lazy eye) and size (Lemmy is small and Iggy is tall and thin, the latter more apparent in their redesign). As of New Super Mario Bros. Wii, Lemmy's grown a ponytail and gotten smaller, and Iggy instead got green palmtree hair and a leaner physique.
  • Evil Genius: Iggy (and Ludwig) fill this role, but it's only apparent in spinoff material (adventure books in Iggy's case); however, this is still implied in the games (due to his recurring Chain Chomp contraption).
  • Four Eyes, Zero Soul: He is the only one who wears glasses (not counting Roy's sunglasses), and the most maniacal.
  • Giggling Villain: Iggy's style of laughter. He makes up for this by never stopping.
  • Keet: Lemmy and Iggy. Lemmy in a cute, childish way, and Iggy in a manic, disturbing way.
  • Laughing Mad: Iggy's been shown to have this trait in New Super Mario Bros. Wii. Mad Scientist indeed. Note that in the hallway up to his boss battle, you can hear him giggling with no abandon, while the other six would quietly wait for you to enter their arena. It gets even worse once the battle actually starts.
  • Lean and Mean: The other most notable change in Iggy's redesign. Although it was never previously clear how tall he was in comparison to the others, he eventually became the indisputably tallest of the Koopalings, and gained a lanky body shape to go with it.
  • Multicolored Hair: Iggy's original design had rainbow hair.
  • Nerd Glasses: His most notable feature, especially before his redesign. The lenses themselves tend to alternate between giving him demented-looking irises as seen in the picture, or the standard nerdy spirals.
  • Single-Minded Twins: Hip and Hop in the cartoons. Not so much in the games, where their personalities are polar opposites (Goofball Idiot and Insane Genius respectively). Though in the comics Lemmy was the only one capable of understanding Iggy's gibberish symbol speak.
  • You Gotta Have Blue Hair: Iggy had rainbow before the redesigns; afterwards, however, it becomes green.

Roy Koopa
Voiced by: Naoki Tatsuta (original video animations), Gordon Masten (The Adventures of Super Mario Bros. 3 and Super Mario World), Don Falcone (2009-present)

Roy Koopa, a big bad guy with cool shades. Named "Bully" in the DiC adaptations.

  • Bald of Evil: Roy and Wendy are the only Koopalings without hair.
  • Brilliant, but Lazy: Implied by Roy's trophy in Super Smash Bros. for Nintendo 3DS / Wii U, which states that he can go from slacker to soldier very quickly.
  • The Brute: He is quite big and muscular, only losing to Morton.
  • The Bully: His cartoon incarnation is called "Bully", and he certainly lives up to the name.
  • Cat Smile: Roy, Larry, and Ludwig invoke this, due to the feline shape of their mouths and their default expressions.
  • Cool Shades: As a reference to musician Roy Orbison, who he's named after.
  • Dumb Muscle: Roy has shades of this in Mario & Luigi: Paper Jam.
    Roy: What is this? A book? Guess those losers must've dropped it. I wonder if it's important. Nah, books are dumb. Into the trash it goes!
  • Jerk Jock: Only in the cartoons.
  • One Steve Limit: Averted in Super Smash Bros. for Nintendo 3DS / Wii U where Roy from Fire Emblem: The Binding Blade is also a playable character. The promotional material likes to picture them as rivals.
  • Real Men Wear Pink: Roy is literally pink all over: pink skin/scales, pink shell, pink shades... Although as of New Super Mario Bros. Wii, his shell has been made purple to avoid conflict with Wendy's shell color in their newly established color coordination. Still the same principle, though.

Lemmy Koopa
Voiced by: Naoki Tatsuta (original video animations), Tara Strong (The Adventures of Super Mario Bros. 3 and Super Mario World), Lani Minella (2009-present)

Lemmy Koopa, a lackadaisical, cross-eyed (and very tiny) clown who is more than a lot nutty. Named "Hip" in the DiC adaptations.

  • Cloudcuckoolander: In Nintendo Comics System, though he didn't actually appear to be as stupid as everyone made him out to be.
  • Creepy Twins: Iggy and Lemmy, especially in the cartoons. Distancing them from this trope may have been the reason Iggy was so radically redesigned compared to the others.
  • Dangerously Genre Savvy: He uses bombs instead of harmless rubber balls in New Super Mario Bros. U.
  • Divergent Character Evolution: Iggy and Lemmy were originally close enough in looks to be made twins in the spinoff cartoons, the main differences being the eyes (Iggy wears glasses and Lemmy has a lazy eye) and size (Lemmy is small and Iggy is tall and thin, the latter more apparent in their redesign). As of New Super Mario Bros. Wii, Lemmy's grown a ponytail and gotten smaller, and Iggy instead got green palmtree hair and a leaner physique.
  • Improbable Weapon User: Lemmy's spell of choice? Giant rubber balls that don't even hurt you.
  • Keet: Lemmy and Iggy. Lemmy in a cute, childish way, and Iggy in a manic, disturbing way.
  • Magical Clown: Whenever he gets his hand on a magic wand. It's worth noting that while his siblings' wands shoot magic fireballs, his shoots circus balls. In New Super Mario Bros. Wii, Kamek adds in even more magic by causing Lemmy's bouncy ball to grow huge.
  • Minion with an F in Evil: Especially in the Nintendo Comics System incarnation. It went so far that in the story Bowser Knows Best, when all the Koopalings royally screw up, Bowser gets mad at them all — "except you, Lemmy. I know you're a blithering idiot!"
  • Monster Clown: Lemmy has a bit of a circus motif, with his colorful hair and use of bouncy balls. His airship in New Super Mario Bros. U is even decorated like a circus tent.
  • Multicolored Hair: Lammy has rainbow hair.
  • Older Than They Look: He is the smallest of the Koopalings, is the most childish and playful, and doesn't seem to really care about Bowser's world domination conquest. Naturally, he was implied in an early player's guide to be the second oldest after Ludwig.
  • Outside Ride: In New Super Mario Bros. 2, Larry and Lemmy have to hang off the Koopa Clown Car's edge due to the lack of room. This is also the case in in the final boss fight of Puzzle and Dragons. However, in the latter's final battle, whenever the Bowser + Koopaling combo use a spell, Larry can still be seen hanging where he was, but Lemmy is somehow seen hanging off the edge of the Junior Clown Car.
  • Punch Clock Villain: According to the Super Mario Bros. 3 Nintendo Power stategy guide, Lemmy doesn't really care about Bowser's plans, and would rather join the circus.
  • Single-Minded Twins: Hip and Hop in the cartoons. Not so much in the games, where their personalities are polar opposites (Goofball Idiot and Insane Genius respectively). Though in the comics Lemmy was the only one capable of understanding Iggy's gibberish symbol speak.
  • Too Dumb to Live: In Lemmy's fight in New Super Mario Bros. U, it's possible to touch Lemmy's bombs on your GamePad to make them explode before he has the chance to throw them. And he will mime throwing them anyway.
  • Weaponized Ball: Lemmy rides around on a rubber ball and tries to run you over with it. He also throws around other balls that bounce you around.
  • You Gotta Have Blue Hair: Lemmy has rainbow hair.

Ludwig von Koopa
Voiced by: Naoki Tatsuta (original video animations), Michael Stark (The Adventures of Super Mario Bros. 3 and Super Mario World), Mike Vaughn (2009-2014), David J. Goldfarb (2014-present)

Ludwig von Koopa, a crazed composer with a sadistic streak. Named "Kooky" in the DiC adaptations.

  • Breath Weapon: He was the first of the Koopalings to show this ability, as he used it in his battle in Super Mario World. Later, they all used fire breath in Mario & Luigi: Superstar Saga.
  • Cards of Power: He's the only boss in Mario & Luigi: Paper Jam who uses Battle Cards. Failing to dodge his and Larry's attacks during their boss battles results in them getting "Dark Star Points", much like the regular Star Points that the Mario Bros. and Paper Mario get for successful Action Commands. After getting enough Dark Star Points, Ludwig will use a Battle Card.
  • Cat Smile: Roy, Larry, and Ludwig invoke this, due to the feline shape of their mouths and their default expressions.
  • The Dragon: Before Bowser Jr. was introduced, Ludwig was said to be Bowser's second-in-command. He doesn't seem to have forgotten this in Mario & Luigi: Paper Jam, despite the other Koopalings thinking of themselves more as equals.
  • Double Jump: In New Super Mario Bros. Wii, Ludwig has learned to quadruple jump. Or more accurately, he's learned Yoshi's Flutter Jump.
  • Evil Cripple: The book Pipe Down! revealed Ludwig is partially deaf note , though in the best ending his hearing is restored by an explosion.
  • Evil Genius: Ludwig (and Iggy) fill this role, but it's only apparent in spinoff material (cartoons in Ludwig's case); however, this is still implied in the games (Ludwig being described as among the smartest of his peers).
  • Genius Bruiser: He was implied to be smart enough to develop and design his own mech, classy enough to like Opera and the like, and is also powerful enough in combat. A tip from the fourth Super Smash Bros. indicates "You could call him the brains of the Koopalings". Taken up a notch in his cartoon "Kooky" counterpart who is a Mad Scientist.
  • Informed Attribute: A Mario Kart 8 Direct described Ludwig as a "showy Anti-Hero".
  • Leader Wannabe: In Mario & Luigi: Paper Jam, it's revealed that Ludwig isn't the leader of the Koopalings, or at least that the other Koopalings don't consider him as such. He just likes to think he is.
  • Mad Artist: In the games, coupled with Evil Genius (considering that he seemed adept enough in technology to utilize a mech that looked very sophisticated in Yoshi's Safari).
  • Small Name, Big Ego: In the cartoons and later games (though the "small name" bit is a lot more downplayed given his rank). This is shown best in Mario & Luigi: Paper Jam, where he views himself as the leader of the Koopalings despite the others not acknowledging that.
  • Smug Snake: He chuckles confidently to himself in his battle intro in the New Super Mario Bros. games, and Mario Kart 8 and Super Smash Bros. for Nintendo 3DS / Wii U explicitly describe him as a pompous show-off.
  • The Usurper: Ludwig is implied to have eyes on the Koopa throne. In New Super Mario Bros. Wii, he was the remaining Koopaling on the airship that abandoned the next in line, Bowser Jr., in World 6; presumably, he also attempted the same in World 4, although it is unknown if either instance was deliberate or accidental. Late in Mario & Luigi: Paper Jam, he self-appoints himself "a real leader" and even complains that he's been "dethroned" upon defeat (much to Larry's chagrin, who casually calls his brother "boss" but would loathe to call him "king").
  • The Von Trope Family: His full name is Ludwig von Koopa for some reason.
  • You Gotta Have Blue Hair: Along with Larry.

Does Baby Mario want to go to Bowser's castle? I'll take him there in a hurry!
"Welcome!!! Yoshi, if you would be so kind, please HAND OVER THE BABY!"
Debut: Super Mario World 2: Yoshi's Island

An evil Magikoopa, the turtle wizard Kamek has been serving Bowser since the Koopa King's infancy and is one of his most trusted minions. He flies around on his broomstick bringing woe to Mario and his pals, but usually prefers to sic giant monsters on our heroes instead of tangling with them head-on. Slightly confusingly, "Kamek" is also the general name of the Magikoopa species in Japan and Nintendo of Europe's localizations.

Tropes associated with Kamek:
  • Affably Evil: Kamek is usually quite polite, if witty and sarcastic, even using terms of endearment to refer to Yoshi and politely asking him to turn over baby Mario.
  • Arch-Enemy: To the whole Yoshi race, even though Baby Bowser is nominally behind him.
  • Badly Battered Babysitter: When Bowser was but a child, Kamek found himself stomped on, ground-pounded, and yelled ay by his bellicose ward on a regular basis.
  • Beleaguered Assistant: In Partners in Time, where he's forced to cater to the whims of the bratty Baby Bowser.
  • Big Bad: Of the Yoshi's Island series.
  • Brainwashed and Crazy: In Super Mario RPG, where he is being controlled by Smithy's gang until you knock some sense into him.note 
  • The Cameo: The Magikoopa that sends Mario off into space in the opening of Galaxy is him.
  • Evil Sorcerer: As the best of the Magikoopas, Kamek is responsible for enlarging and shifting Bowser's minions, and often Bowser himself.
  • Faux Affably Evil: In some portrayals his civil manner comes off more as a condescending facade, as he seems to actually take great delight in messing with the heroes.
  • Flunky Boss: In his second battle with the Bros. in Dream Team. He can summon a pack of Goombas and Spinies for an attack, and can also summon a herd of Dry Bones.
  • Flying Broomstick: His transportation method of choice in most of his appearances.
  • Flying Weapon: As Giant Kamek in Super Princess Peach, his (also giant) wand floats beside him and he directs it by waving his arms.
  • The Heavy: Bowser may be the Big Bad of Sticker Star, but he appears only at the start and end of the game and has no dialogue. Kamek shows up repeatedly throughout the worlds to make your life difficult.
  • Instant Runes: The Magikoopas shoot what look like PlayStation button symbols at you.
  • King Mook: He looks no different from the other Magikoopas, however. In some appearances his hat and sleeves have white trim while the other Magikoopas' don't, but in others that's not the case, or all Magikoopas have that feature.
  • King of Games: In Mario Party Advance, he holds the title of "Game Mage".
  • Magical Nanny: To Bowser when he was young, and whenever he's assisting the Koopalings.
  • Make My Monster Grow: Most of the bosses in the Yoshi's Island series are created by him this way. He does it to himself for a change in Super Princess Peach, and to Bowser in New Super Mario Bros.
  • Mana Burn: In Sticker Star, he has a spell that randomly destroys one of your stickers. Hope you weren't saving that one for hitting a boss's weakness!
  • Nice Job Breaking It, Herod!: If anything, Kamek's scheme to prevent the conflict between Mario and Bowser by getting to Mario while he was still an infant only accomplished the opposite effect; in effect, he began the conflict by getting the ball rolling.
  • Oh Crap!: In Yoshi's Island when his screaming wakes up Baby Bowser. The royal pain promptly flattens him. He also gets this earlier when he finds out that by throwing an egg at Naval Piranha before he shows up, you already killed it.
  • Opaque Lenses: His lenses are a pale white which mask his eyes.
  • Parental Substitute: For Bowser when he was young.
  • Psychic Powers: Including clairvoyance, precognition, hypnosis, and telekinesis.
  • Reality Warper: Can use every effect spell an ordinary Magikoopa can, not to mention being able to Time Travel in Yoshi's Island DS and turn the entire area around Peach's Castle into Mordor in New Super Mario Bros. U.
  • Recurring Boss:
    • Fought three times in Sticker Star.
    • Also fought three times in Dream Team, towards the end.
    • In Yoshi's New Island, he is the boss of every mid-world fortress.
  • Red Oni, Blue Oni: The blue to Bowser and Bowser Jr's red.
  • Robe and Wizard Hat: He's clad in the blue robes and peaked hat of the Magikoopas, though his occasionally have white trim to set him apart.
  • Sad Battle Music: The theme that plays in the room where he is attacking Yoshi right before entering Baby Bowser's room in Yoshi's Woolly World just screams this.
  • Scary Shiny Glasses: His glasses are a part of his scary shadow in every appearance.
  • Shoe Slap: For the second and third battles in Sticker Star, he turns all of your stickers into... sandals, forcing you to fight by slapping him in the face with flip-flops.
  • Smug Snake: In Sticker Star and Dream Team. As mentioned under Faux Affably Evil, he just loves to patronize.
  • Standard Royal Court: He and the other Magikoopas are the token wizards of the kindgom.
  • Squishy Wizard: Very much so in Sticker Star. Compared to the staggering amounts of health chapter bosses boast, Kamek has a measly HP total of 20 each time you face him, relying on trickery to avoid being curb-stomped.
  • Teleport Spam: In the final hallway before reaching Bowser's room in Yoshi's Island, Kamek confronts you personally, shooting at you with his magic and transforming blocks into random Mooks, but if you try to hit him at all he teleports away.
  • Time Paradox: In Yoshi's Island DS, one Kamek steals Baby Bowser from another Kamek. What?
  • The Unfought:
    • In Yoshi's Island and Yoshi's Island DS, despite being the main antagonist. Averted in Yoshi's New Island, where he's a Recurring Boss.
    • Also in Super Mario Galaxy, where he blasts Mario into space in the opening, then just disappears for the rest of the story.
    • This is even the case in Puzzle & Dragons: Super Mario Bros. Edition. The opening confirms that he was the one responsible for causing the Mushroom Kingdom to overflow with orbs. This time, he's never even encountered by the heroes in their adventure, unlike the above two examples.
  • Villainous Breakdown: In Yoshi's Island, Yoshi consistently stymies his efforts to collect Baby Mario, leaving him so agitated that by the time you reach Baby Bowser's room he can barely form coherent sentences.
    YOU! are n-n-not welcome HERE!!! Yoshi, please hand OVER THE BABY!
  • Villainous Crossdresser: He disguises himself as Peach in New Super Mario Bros. Wii and Mario & Luigi: Dream Team. In the latter, he inadvertently reveals he likes her dress. The Bros. didn't fall for his Peach disguise the second time in Dream Team; instead, they got ready to attack him.
  • What Happened to the Mouse?: After he blasts Mario off into space in Super Mario Galaxy, he just disappears from the rest of the story.
  • Wizards Live Longer: A possible explanation why he hasn't aged a bit in the present day games.
  • Wolfpack Boss: His third and final battle in Dream Team, where he makes specialized clones of himself for attacking, buffing, and healing.

    The Koopa Troop
"Koopa Pack, ATTACK!"

Bowser's loyal legion of minions, the Koopa Troop (also known as the Koopa Clan) is thousands strong and made up not only of Koopa Troopas but also Goombas, Piranha Plants, Spinies, Bob-ombs, Bullet Bills, and other assorted baddies. Most of them aren't that bad, though; they just have a nasty boss.

The Koopa Troop is made up of a wide variety of "races"; the most common include:

  • Koopas: A race of anthropomorphic turtles. Bowser's rank and file, the Koopas include numerous variants, including the common Koopa Troopas, the winged Koopa Paratroopas, the cloud-riding Lakitus, the animal-like Buzzy Beetles and Spinies, and so on. Their shells seem to be articles of clothing rather than part of their anatomy. Debut: Mario Bros. (as "Shellcreepers").
  • Goombas: These guys are the worst. Not only are they pathetic soldiers, but they're traitors, to boot! These armless shiitake mushrooms with Big Ol' Eyebrows once served the Mushroom Kingdom, but defected to Bowser. Debut: Super Mario Bros.
  • Piranha Plants: Barely-sentient carnivorous plants with a mouth full of razor-sharp teeth. Piranha Plants commonly live in pipes. Debut: Super Mario Bros.
  • Dry Bones: Skeletal Koopa Troopas that come back to life not long after being stomped. They usually stay in castles. Debut: Super Mario Bros. 3.
  • Chain Chomps: Black orbs with eyes, sharp teeth, usually a chain and not much else. They act like and seem to be the local equivalent of dogs. Unchained ones are just 'Chomps'. Debut: Super Mario Bros. 3.
  • Cheep Cheeps: Goggle-eyed fish that swarm underwater (and sometimes jump into the air). Debut: Super Mario Bros.
  • Bullet Bills: Living artillery that get shot out of cannons. Debut: Super Mario Bros.
  • Bob-ombs: Walking, wind-up bombs that explode when they get close to Mario. In the RPGs, we learn that they can reform after blowing up. Debut: Super Mario Bros. 2.
  • Boos: Nasty little blobs of ectoplasm who chase Mario relentlessly. They're painfully bashful, though, and stop moving to cover their faces when anyone looks at them. Debut: Super Mario Bros. 3.
  • Lava Bubbles: Fireballs that leap out of the lava pits that Bowser so loves. Sometimes called "Podoboos" or, less often, "Sparkies". Debut: Super Mario Bros.
  • Monty Moles: Near-sighted little mammals that live underground and have a knack for machinery. Debut: Super Mario World.
  • Shy Guys: Humanoid creatures that always hide their faces behind masks, hence the name. Like the koopas, there are several varieties and colors, and they sometimes carry weapons. Debut: Super Mario Bros. 2.
  • Thwomps: Giant rock creatures lined with thick spikes and with perpetually angry expressions. They drop down to crush enemies and are often positioned in key spots to provide maximum annoyance. Debut: Super Mario Bros. 3.
And these are only half of 'em!

Tropes associated with the Koopa Troop:
  • Action Bomb: Bob-ombs' main shtick.
  • A Day in the Limelight: Shy Guys are one of the less frequently occurring enemies, yet feature prominently in Yoshi's Island and Yoshi's Story
  • Adorable Evil Minions: Koopa Troopas, Shy Guys, Bloopers, and, in an Ugly Cute way, Goombas, Boos, and Dry Bones.
  • Angry Guard Dog: Chain Chomps were inspired by a childhood memory of Miyamoto's, where he was almost mauled by one of these but saved by a chain that was just too short. They seem to be the in-game equivalent of dogs.
  • Always Chaotic Evil: They can come off as this in the main series, however in spinoffs some are shown to have their own personality and there are even a few good members of these species that don't live under Bowser's rule.
  • Anthropomorphic Food: A consistent design trend with Goombas. Standard Goombas look like mushrooms, Galoombas look like chestnuts, and Goombrats look like persimmons.
  • Anthropomorphic Shift: Starting in Super Mario World, Koopa Troopas started walking on two feet and wearing shoes.
    • Anthropomorphic Zig Zag: In New Super Mario Bros., they're bipeds, but in Super Mario Galaxy, they're now back to being quadrupeds, but in New Super Mario Bros. Wii, they're bipeds again, and in Super Mario Galaxy 2, they're quadrupeds again, and in Super Mario 3D Land, they're bipeds again.
  • Art Evolution: Enemies will often change in appearance depending on the games. Skeeters in particular, as they've never been in two games with the same appearance.
  • Artifact Title: Tox Boxes looked like industrial metal boxes with spray-painted faces in Super Mario 64, gaining their name from "toxic" and "box. In Super Mario Galaxy, they're made of stone and resemble oni to make them more like Thwomps, but they retain the now-irrelevant name.
  • Badass Army: They may not appear like it, but they have conquered the Mushroom Kingdom multiple times, assaulted the Star Spirits, and kidnapped the local Crystal Dragon Jesus. In Dream Team, several members of the Koopa Troop don't appear as enemies until latter in the game, but become the brunt of the enemies encountered afterwards. Including the Goombas.
  • Bedsheet Ghost: The Boos.
  • Berserk Button: Wigglers are friendly caterpillars, but if you jump on them, they'll become angry, turning red and moving much more quickly.
  • Breath Weapon: Fire Bros. originally spat fireballs when they debuted in Super Mario Bros. 3, though later they were shown to throw them like Fire Mario does.
  • Canon Immigrant: All the enemies that debuted in Super Mario Bros. 2 originated in Doki Doki Panic (except Clawgrip), the game it was reskinned from. Nonetheless, they fit in well.
    • This is mostly due to Miyamoto having been the lead designer of the game, and supposedly had more involvement in it than The Lost Levels.
  • Cool Airship: They sometimes ride in these, which are essentially pirate ships held up by propellers in the air.
  • Dem Bones: The Dry Bones.
  • The Determinator: Goombas, according to Mario Party 9.
  • Elite Mooks: The Hammer Bros., Lakitus, Magikoopas, Chargin' Chucks, and other bigger and badder Koopa variants.
  • Epic Flail: Being already a very heavy sphere on the end of a chain, a Chain Chomp can be wielded this way. Bowser does so in Super Mario RPG and, more inexplicably, it's the final weapon unlock in Bayonetta 2.
  • Expressive Mask:
    • Bandits may dress like Shy Guys but their masks are capable of expressing a wide range of emotions. Their default is a good old fashioned Psychotic Smirk.
    • Shy Guys have occasionally been able to move their masks, but mostly they're only capable of manipulating their mouth-holes. You will rarely find fully expressive Shy Guys.
  • Evil Counterpart Race: The Goombas (who may resemble mushrooms but are actually chestnut-monsters) to the Toads, though some spinoffs like the Paper Mario games have good Goombas.
  • The Faceless: Shy Guys (and to a lesser extent their Snifit cousins) have only ever been seen with the same three-hole mask since the days of Doki-Doki Panic and rely on body language to properly express themselves. They've rarely been seen without their masks, and only by Luigi. In Luigi's Mansion, there are ghostly Shy Guys that manage to be even more faceless by virtue of masks without eyeholes. On the flipside, these ghosts are capable of losing their masks, revealing only a pair of glowing eyes under the hood, which may mean that Shy Guys are literally facelessnote .
  • Fantasy Axis of Evil: Each type and its variants fills a particular niche.
  • Our Ghosts Are Different: It's never made quite clear what exactly the Boos are.
  • Giant Mook: See the Super Smash Bros. page for some specific examples, though it isn't limited to that game.
    • Big Boos and Banzai Bills are one of the earliest examples in Super Mario World.
      • Giant Land from Super Mario Bros. 3 is a far earlier example, where Koopas and Goombas of the big island absolutely dwarfed Mario.
  • The Goomba: The one and only.
  • Hidden Depths: As the Mario RPGs show, a lot of the Koopa Troop members show that the troops are more intelligent than they seem. At least one Dry Bones enjoys table tennis, and even knows of how it first came to be.
  • King Mook: Many of the enemy races have a powerful ruler with unique powers who reports directly to Bowser, including Goomboss (Goombas); Kamek, Kammy Koopa, and Kamella (Magikoopas); Petey Piranha (Piranha Plants); King Bob-omb (Bob-ombs); King Boo (Boos); and General Guy (Shy Guys); not to mention Bowser himself. Some races have giant or extremely powerful versions that have "King" in their name, like King Bill (NSMBWii, the Bullet Bill line) and King Kaliente (Super Mario Galaxy, the Blooper line).
  • Invincible Minor Minion: Lava Bubbles are invincible to everything but stars. (and later ice balls) Boos are similar, though in some games they're weak to the light.
  • Just Following Orders: Bowser's minions very rarely bear any personal grudge against the heroes. They just really like Bowser a lot and follow him out of admiration. They have even cooperated and even allied with Mario and crew on occasion in the RPG and Party games and some become playable in the Sports and Kart games.
  • Mascot Mook: The Goomba and Koopa Troopa are very much symbols of the series, just as much as Mario himself.
    • Shy Guys are the mascots of games with Yoshi as the central protagonist.
  • Mecha-Mooks
    • Bullet Bills and Bob-ombs, among others (Mechakoopas, Torpedo Teds, etc.).
    • Chomps are also implied to be these.
  • Monogender Monsters: The Japanese site for 3D Land refers to Pom Pom as the lone female in Bowser's army. This implies that all of his common mooks are male.
  • Monster Town: Mainly in the Paper Mario games; most Koopas and Goombas are apparently normal homebodies just like the Toads, it's just the ones we see most often are Bowser's foot soldiers.
  • Monster Clown: Amps are often shown with clown-like faces.
  • Morality Pet: In the RPGs, the mooks occasionally function as this to Bowser. He even lets some stay in the Monster Town in Super Mario RPG and forgives those three mooks who tossed him in a safe (while Brainwashed) in Bowser's Inside Story.
  • Musical Theme Naming: The Boos, who were originally named Boo Diddlies, an obvious riff on Bo Diddley.
  • My Species Doth Protest Too Much: Most notable in the first two Paper Mario games have helpful individual minions as your allies, though they also fight their usual mook counterparts.
  • The Spiny: Again, Trope Namer.
  • Names to Run Away from Really Fast: In Japan, Bullet Bills are known as "Killer" and Banzai Bills are called "Magnum Killers."
    • Bullet Bill also counts, being named after, well, bullets. Banzai Bills have also been referred to as Magnum Bills (at least in the cartoons), Piranha Plants as well.
  • Night of the Living Mooks: Many Koopa Troop races have undead counterparts, most notably Dry Bones (skeletal Koopas).
    • Don't forget the Boos and their many subtypes and allied ghosts.
  • Non-Lethal K.O.: Several games heavily imply that Mario doesn't actually kill them and they can survive being stomped flat. It's most consistent and explicit with Goombas, Koopas, and Bob-Ombs, though the others may vary from game to game.
    • Other games invert it and imply they do indeed die, notably when defeat a Boo is defeated in the first mission of Course 5 in Super Mario 64, they taunt you by saying "Ghosts... ...don't... ...DIE!"
    • The Koopalings in particular have been melted, exploded, disintegrated, etc., but always turn up fine next time.
  • Perpetual Frowner: The Thwomps tend to be this when their mouths are closed.
  • Pulling Themselves Together: Dry Bones and their subspecies are known for reassembling seconds after an attack causes them to fall apart.
  • Punch Clock Villain: The Koopa Troop themselves are not The Evil Army, following Bowser out of genuine admiration more than anything other than the idea that they can be promoted over Bowser and boss him around and seem to have no guff with Mario on downtime. The Lakitus are a stand-out example, appearing regularly as friendly camera crews in Mario sports games.
  • Reality Warper: Magikoopas' spells have many different effects on objects, enemies, etc.
  • Red Eyes, Take Warning: Later designs of Buzzy Beetles have this, and you better take warning since they are flame-resistant.
  • Removable Shell: Mario can force a Koopa out of its shell in order to ride it or use it as a weapon.
  • Ridiculously Cute Critter: The Koopas.
  • Shock and Awe:
    • Fizzlits, blob-like purple creatures whose attack pattern is to melt into an electric puddle to try to electrocute Mario.
    • The red Thunder Lakitu can launch ball lightning, an ability that first appeared in the Super Mario Bros.: Peach-Hime Kyushutsu Dai Sakusen! anime movie, as a reference to the Shinto god Raijin.
  • Superpowered Mooks: The Super Koopas in Super Mario World and the Tanoombas in the Mario & Luigi series. There are various Super Leaf and Super Bell-using mooks in 3D Land and 3D World respectively.
  • Throw The Hammer: Hammer Bros. fight this way. There are numerous variations of Hammer Bros. that all use different weapons, such as Boomerang Bros., Fire Bros., Ice Bros., Sledge Bros. and even rarer kinds like Yo. Bros and Chomp Bros.
  • Took a Level in Badass: Throughout the Mario & Luigi series. They went from being easily beaten and/or brainwashed in the first three games to forming the majority of the lategame enemies of their own will (and all this under Bowser, as opposed to the other games) in Dream Team.
  • Turtle Power: The Koopas.
  • Underground Monkey: The blue subterranean Goombas from Super Mario Bros. are one of the first examples. Many, many variants show up, particularly in the RPG spinoffs.
    • Bullet Bill comes in a variety of calibres, including the massive Banzai Bill and the underwater Torpedo Ted (both from Super Mario World).
    • The Paper Mario games have plenty, including Elite Mook Koopatrols in full plate armour. (with spikes)
  • Undying Loyalty: Pun aside, Tattles from the first two Paper Mario titles imply that this is literally the case with Dry Bones under the Koopa King.
  • The Unintelligible: Several spin-off titles show that Dry Bones are only capable of speaking in "clacks", though their actual words are in parentheses for our convenience. Despite this, however, other characters seem to be able to understand them just fine.
  • You Don't Look Like You:
    • The Boos in Super Mario Sunshine are freakin' weird to look at; normal Boos are known for their iconic wicked smiles, while Boos from Isle Delfino all have the same dopey expression and let their tongues loll out. It's unknown if this is their natural state or an effect of Shadow Mario's meddling.
    • All the enemies in Super Mario Sunshine look different from their Mushroom Kingdom counterparts, even Delfino King Boo.
    • The Goombas in Super Mario World are round instead of mushroom-shaped. The Japanese version actually acknowledges these as a separate species (Kuribon as opposed to the usual Kuribo). In Super Mario 3D World, these round "Goombas" were reintroduced under a new name as Galoombas (and of course they're separate from the usual Goombas).

    Petey Piranha
"I will CRUSH you!"
Voiced by: Toru Minegishi (2002-present)

Petey is a mutated Piranha Plant who's uprooted himself and can walk around on stubby rootlike legs and, miraculously, fly around clumsily with his little leaf-hands. He's physically among the largest of Bowser's baddies, not to mention one of the dumbest. He's known as "Boss Pakkun" in Japan, as Piranha Plants are called "Pakkun Flowers" in Japanese.

Tropes associated with Petey Piranha:
  • Dumb Muscle: He's not very intelligent, but he makes up for it with his strength. In some of his playable appearances, he's actually stronger than Bowser is.
  • Elemental Rock-Paper-Scissors: He's weak to both fire and ice in Partners in Time.
  • Extreme Omnivore: He can eat sports equipment and trophies among other non-edibles.
  • Eyeless Face: Like all members of his species. Doesn't stop him from able to do things like go-karting though.
  • Fast Tunnelling: In Partners in Time.
  • Flight: He can achieve it by flapping his leaves, but is obviously straining himself.
  • Flunky Boss: The goop he pukes up in Super Mario Sunshine can spawn enemies, and he can spit Nipper Plants in Super Princess Peach.
  • Friendly Enemy: While this is true of the entire Koopa-Troop to an extent, Petey tends to be downright amicable when "off the clock"
  • Green Thumb: His Mega Strike in Mario Strikers Charged has him enclose himself in a summoned plant bud.
  • Grievous Harm with a Body: He attacks the player with cages containing the captive Peach and Zelda in Super Smash Bros. Brawl.
  • Ground Pound: Uses a maneuver similar to this in New Super Mario Bros.
  • King Mook: Of the Piranha Plants.
  • Large and in Charge: According to the official height chart, he's actually taller than Bowser. For the record, Bowser is listed as about 8'7", while Petey is a whopping 12'9".
  • Make Me Wanna Shout: Oddly, in Super Princess Peach.
  • Mighty Glacier: In his playable appearances, he's ridiculously strong and slow.
  • More Teeth than the Osmond Family: As is typical of Piranha Plants.
  • Mutant: Various bios describe him as one.
  • Mysterious Past: In his debut, it was assumed he was just created by Bowser Jr., only for Partners in Time to show he's been around for years, and even worked for the Shroobs.
  • Off Model: In Mario Pinball Land, Petey looks... weirder than usual.
  • Older Than They Look: Partners in Time reveals he looked exactly like he does in the present day while everyone else was just a toddler.
  • Poisonous Person: One of his attacks is vomiting sludge.
  • Roar Before Beating: Gets a rather disproportionately epic one in Super Mario Sunshine.
  • She's a Man in Japan: And English-speaking regions, too, actually, but Petey is female in Germany (where "she" is known as Mutant Tyranha) and France (where "she" is named Flora Piranha, referring both to the petals on "her" head and "her" gender).
  • Shockwave Stomp: In Super Princess Peach.
  • Those Two Bad Guys: Usually partnered with King Boo in spin-off games.
  • Took a Level in Badass: Pretty easy to fight in Super Mario Sunshine, but in his playable appearances Petey is often a very strong character with great playability. And his appearance in Super Smash Bros. Brawl actually made him somewhat scary. In Mario & Luigi: Partners in Time, New Super Mario Bros., and Paper Mario: Sticker Star, he actually gets somewhat challenging.
  • Warmup Boss: He's an early boss in Sunshine, and the first boss of The Subspace Emissary in Brawl. In both appearances, he is easy to defeat.
  • With Great Power Comes Great Insanity: In Sticker Star, like every other boss.
  • Underwear of Power: Wears a red polkadot speedo that matches his head.
  • The Unintelligible: Except when under the influence of a Royal Sticker.
    • Otherwise, as seen in Mario Super Sluggers when talking to him:
  • Your Size May Vary: In Super Mario Sunshine, he was as large as a small house. In spin-offs, he is much smaller (though still larger than everyone else).

    King Boo
"If you hear me laughing, that means you're doomed!"
Voiced by: Toru Asakawa (2001-present)

King Boo, a big ol' round blob of ectoplasm. He first appeared in Luigi's Mansion as the final boss that Luigi must face before clearing his house of its ghost infestation. Since then, he's appeared in the Mario Kart series and some of the Mario sports titles before reprising his role as the Big Bad and Final Boss in Luigi's Mansion: Dark Moon, in which King Boo destroys the eponymous Dark Moon and uses the Evershade Valley ghosts in a mad quest for revenge. He's set apart from the other Boos by his great size, crown, and formidable magical powers (which increase in potency when more of his Boo servants are nearby). In accordance to his subjects, his Japanese name is "King Telesa".

Tropes associated with King Boo:

  • Advancing Boss of Doom: During the final fight in Dark Moon, in between fight phases, King Boo will chase Luigi through an obstacle course in an attempt to flatten him. Also serves as a Shout-Out to Indiana Jones.
  • A Father to His Men: One of the few redeemable traits he has is that he genuinely cares for his fellow Boos, going so far as to even stage a rescue for Boolossus when he was captured by E. Gadd prior to Luigi's Mansion. In Dark Moon, however, he never mentions this and puts his Boos in harm's way on at least one occasion, dropping this trait.
  • Amplifier Artifact: His new crown in Dark Moon.
  • And I Must Scream: Has been on both ends of this trope. Trapped Mario in a painting during Luigi's Mansion, gets sealed in a painting himself at the end of the game, broke out of the painting in Dark Moon, and plans to return the favor to Luigi and his friends. In the remake of Super Mario 64 he also manages to trap Luigi in a mirror.
  • Apocalypse How: Attempts either a Class X-4 or Z, and comes really, really close to pulling it off.
  • Arch-Enemy: Since his introduction in Luigi's Mansion, he's adopted this relationship with Luigi.
  • Authority Equals Asskicking: He's the leader of the Boos simply because he's bigger and stronger than the others.
  • Ax-Crazy: Based on his appearance and actions in Dark Moon, it's safe to say that his defeat in the first game unhinged him a bit.
  • Badass: He managed to escape from E. Gadd's painting, on his own. When he returns in Dark Moon, he manages to destroy the dark moon and take over...seconds after showing up there. He also fights Luigi one-on-one during the Final Boss this time, instead of fighting in a giant Bowser suit.
  • Badass Boast: Gives a terrifying one to Luigi when they finally meet face to face in Dark Moon.
    King Boo: Now who do we have here? Why, if it isn't my old pal Luigi! Or is it Baby Luigi? I can't tell the difference. Hey, remember that time when you trapped me in a painting for all eternity? Good times. But guess what? I got out! And now I'm painting the town red! Yes, it was I who broke the Dark Moon! This power-enhancing jeweled crown of mine made it easy. And now that all the ghosts of Evershade Valley are under my control... it's time to take my rightful place as the supreme ruler of your world! You, that annoying scientist, and all your friends will look great hanging from the wall of my throne room! Aaaaaahahaha!
  • Badass In Charge: Of the Boos.
  • Best Served Cold: In Dark Moon, He plans to turn Luigi and his friends into paintings. He only mentions Luigi, Mario, the Toads, and Gadd as targets. Whether he has plans to do this to anyone else is... uncertain. He states that he's also after all of their friends, though he doesn't specify which.
  • Beware the Silly Ones: Don't be fooled by his simple appearance and snarkiness, he's much more dangerous than he looks.
  • Big Bad: In Luigi's Mansion and its sequel.
  • Blow You Away: Utilizes this on Luigi if he tries to enter the Secret Altar prematurely in Luigi's Mansion.
  • Bond Villain Stupidity: Some background scenes suggest that King Boo is capable of ambushing Luigi several times over the course of Dark Moon, suggesting that this whole thing is sadistic "fun" to him.
  • Brains and Brawn: The brains to Petey Piranha's brawn. While both are classed as Power type characters in the Mario Baseball series, King Boo's batting stat is not as high as Petey Piranha's, and he has a slightly weaker throwing arm compared to Petey.
  • Cardboard Prison: That painting he was trapped in at the end of Luigi's Mansion? He broke himself out. And this was before he found his new crown.
  • The Chessmaster: Masterminded the plot to bring all the ghosts in Evershade Valley under his control in Dark Moon. Especially evident in the opening of E-3, where it makes it plain that he knew the whole time you were spying on him and was spying right back at you.
  • Co-Dragons: With Goomboss and Chief Chilly in Super Mario 64 DS, as Bowser has them guard Mario, Luigi, and Wario.
  • Creepy Shadowed Undereyes: Acquired these in Dark Moon.
  • Cuteness Proximity: His reaction to the Mini Boos in Mario Super Sluggers.
  • Dangerously Genre Savvy: In Dark Moon. First, he breaks the Dark Moon to get all the ghosts in Evershade Valley under his control. When Mario shows up to investigate, he captures him and several Toads in paintings to ensure that there's no interference. When Luigi shows up and begins tracking him, he has Big Boo set up an ambush in the train exhibit to throw him off the trail. Finally, after Luigi gets the final piece of the Dark Moon, he abducts him through the Pixelator and drops him in his illusion to get a crack at him. Though the fact that he loses the final piece counts as a moment of Genre Blindness, it's justified in that if he can defeat Luigi, he can simply break the moon again with no interference.
  • Darker and Edgier: In Dark Moon. All his redeemable traits he had in the first game vanish completely making him a pure malignant ghost and one of the evilest villains in the Mario Bros. universe.
  • Deadpan Snarker:
    "Seriously, though, who would actually believe that mansions get given away in contests?! Talk about stupid! What do they feed you Mario brothers anyway... gullible soup?"
  • Disproportionate Retribution: His revenge plot in Dark Moon in general, counts as his wrath extends to those who had nothing to do with his imprisonment, such as the Toads he captures. But his prominent act is after Luigi defeats Big Boo. He rips open a Paranormal Portal to unleash an army of ghosts and conquer the universe in retailiation. Forget disproportionate, that's just overkill.
  • Distinctive Appearances: Stands out among Boos due to his red eyes and blue tounge. And in Dark Moon, his appearance is further altered, the eyes are now shrunken in with a black shadow, making him look more dangerous and insane.
  • Dramatic Irony: Despite Dark Moon not making a flick of effort to hide that King Boo is the Big Bad, Luigi and E. Gadd don't find out until the beginning of E-3.
  • Evil Laugh: Has a distinct giggle from most Boos and he laughs constantly. It almost borders Laughing Mad.
  • Evil Sorcerer: He can whip up a mansion in no time at all.
  • Fangs Are Evil: His fangs are as menacing as his face.
  • Faux Affably Evil: : As his interaction with Luigi in Dark Moon shows, he'll talk to you like your best friend when it's painfully obvious he despises you with every fiber of his being.
  • Final Boss: Of both Luigi's Mansion games.
  • Flight: The fact that this gives him an unfair advantage in spin-offs is lampshaded in Mario & Sonic at the Olympic Winter Games, where he is once again a boss, and does not actually use any skis in the skiing race against him.
  • For the Evulz: While King Boo does have a plan, some of the things he does are purely for sadistic kicks.
  • The Fourth Wall Will Not Protect You: A rather terrifying in-universe example. When you examine the security image before E-3, he turns around within the static image and gives a terrifying Evil Laugh before making the shot fade to static.
  • Go-Karting with Bowser: Despite his deep hatred of Luigi, he has no issues challenging him to a friendly race in Mario Kart Double Dash!! and Mario Kart Wii. In the former, you can team up King Boo with Luigi.
  • Hoist by His Own Petard: Luigi has to hit him with his own summoned spike balls in Luigi's Mansion, and the light cast by his own flames can hurt him if they light nearby candles in Super Princess Peach. And in Dark Moon, Luigi must trick him into being hit by his own spiked balls again to vacumn him.
  • Inconsistent Dub: In Super Mario 64 DS, his name is mistranslated as "Big Boo," even though there is already a boss called "Big Boo" in the game. This was corrected in Mario Kart DS, which used only bosses from Super Mario 64 DS in its Mission Mode.
  • It's Personal: When King Boo and Luigi finally meet face-to-face in Dark Moon, it's quite clear that despite his composure, he really wants Luigi dead. This combines with some Terms of Endangerment to create some really creepy dialogue.
    King Boo: Hey, if isn't my old pal Luigi. Or is it Baby Luigi? I can't tell the difference. Hey, remember that time when you trapped me in a painting for all eternity? Good times.
  • King Mook: Of the Boos, obviously.
  • Knight of Cerebus: Becomes this in Dark Moon. His Laughably Evil tendencies are completely gone, his snarkiness is more restrained, and he becomes downright terrifying.
  • Large and in Charge: Downplayed. He's much larger than the average Boo, but even larger Boos such as Boolossus follow him.
  • Manipulative Bastard: Turned all the benevolent ghosts evil, including the horned Possessors.
  • Mask of Sanity: He acts calm and collected all of the time, but it's shown in Dark Moon that underneath his calm, yet frightening appearance is an insane, unfettered sociopath who is, by the end, steadily breaking down, which becomes especially apparent in his boss fight, in which the background and music start becoming fast-paced and erratic.
  • Master of Illusion: A rare case of the this trope overlapping with Reality Warper. The final level in Dark Moon is called King Boo's Illusion, a pocket dimension he created that he has total control over.
  • Monster Suit: Uses a biological-looking one modeled after Bowser in the final battle in Luigi's Mansion.
  • No-Nonsense Nemesis: Adopts this attitude in Dark Moon after his defeat in the first game, and man does it make him look terrifying.
  • Playing with Fire: He attacks Peach with homing blue flames in Super Princess Peach.
  • Psycho Electro: It's no coincidence that Dark Moon is the game in which King Boo both uses electricity and completely lost it.
  • Purple Eyes: Has them in Dark Moon which goes along with his royalty and super-natural powers.
  • Red Eyes, Take Warning: In some appearances.
  • Remember the New Guy: In Luigi's Mansion, he tries to take revenge on the Mario Bros. for a number of past defeats. This was his first appearance in the series, though he retroactively appears in Super Mario 64 DS as another Big Boo. He also doesn't mention personal defeats in Luigi's Mansion, just the number of times the Bros. have beaten up on Boos.
  • Revenge: The whole plot of Dark Moon is his revenge against Luigi and his friends for his defeat in Luigi's Mansion.
  • Sanity Slippage: His debut appearance portrayed him as a Well-Intentioned Extremist who wanted to protect his fellow Boos. His appearance in the sequel, however, shows his defeat has turned him into an unfettered, sadistic, no-nonsense, sociopath who will do whatever it takes in his mad quest for revenge.
  • Shock and Awe: His crown in Dark Moon can fire lightning bolts.
  • Slasher Smile: His default expression. The teeth help.
  • The Sociopath: In his debut, he showed care for his fellow Boos and worked to protect them. In the sequel, however? He's perfectly willing to eliminate anyone and anything in his path for revenge, and despite having to know by the final battle with him that Luigi's captured at least some Boos (and likely having known beforehand), he never mentions them and only talks about how he will make Luigi and Gadd pay dearly.
  • Supernatural Is Purple: This ghoul gains both purple eyes and a purple crown in Dark Moon.
  • Take Over the World: In Dark Moon, King Boo claims that this is his goal, but it's made very clear that he's more interested in revenge against Luigi.
  • Terms of Endangerment: Gives quite a few to Luigi in Dark Moon.
  • Those Two Bad Guys: Is usually paired with Petey Piranha in spin-offs, in a possible case of Brains and Brawn.
  • Took a Level in Badass: In Luigi's Mansion, his power was directly proportionate to the number of Boos in the vicinity. When Luigi captured them all, it weakened him to where he had to use a life-like puppet of Bowser to fight. His crown in Dark Moon, however, negates this handicap, allowing him to fight Luigi one-on-one with his own power and giving him new abilities such as calling down lightning strikes, summoning spiked balls, creating illusions, etc. "Fight you like a true Boo" indeed.
  • Tranquil Fury: His interaction with Luigi in Dark Moon is a perfect example. Despite his pleasant demeanor to Luigi, you can tell he's seething with rage on the inside.
  • Unexplained Recovery: It took two console-generations worth of games to answer how he managed to escape from the painting at the end of Luigi's Mansion.
  • The Unfettered: Dark Moon shows that King Boo has no limits to his insane desire for revenge. He'll sacrifice anyone and anything. His Boos, other ghosts, even the fabric of the universe itself! Nothing is beneath him as long as Luigi and E. Gadd suffer.
  • Vile Villain, Saccharine Show: As of Dark Moon, he definitely falls into this category. He was pefectly willing to shatter the Dark Moon and break the minds of innocent ghosts and later having his Boos experiment on them to make them stronger and more vicious, effectively making them all unwitting pawns in his mad scheme. And when Luigi defeats Big Boo, he rips open a Paranormal Portal to unleash an army of ghosts, which may also endanger their home dimension, which puts him practically on par with Dimentio in terms of evil.
  • Villainous Breakdown: In Dark Moon, E.Gadd states that King Boo "flipped out" after Big Boo's defeat and summoned a Paranormal Portal to unleash an army of ghosts as a desperate act to slow Luigi down. King Boo's breakdown is further exacerbated after Luigi defeats the Tough Possessor and makes off with the final piece of the Dark Moon. King Boo then intercepts the Pixelator and pulls him back into his illusion. The breakdown continues as the fight wears on, the music and the illusion becoming more erratic and unstable as he nears defeat.
  • Visible Invisibility: His reflection can be seen in the mirror in the background in Super Mario 64 DS.
  • The Voiceless: He doesn't speak in Mario & Luigi: Paper Jam.
  • Well-Intentioned Extremist: In the first game, he seemed to genuinely care for the other Boos. In the sequel, however, he seems to drop this.
  • What Happened to the Mouse?: Completely disappears from the plot of Dark Moon after the Final Battle. Luigi collects his crown, but it doesn't count for money.
  • You Don't Look Like You: His appearance constantly changes throughout the series, leading some to wonder if it's the same character in every game.
    • In his debut in Luigi's Mansion, he looked distinct from other Boos due to his gleaming red eyes and blue tongue.
    • In most spin-offs, like the Mario Party series, he just looks like a regular Boo with a crown.
    • Luigi's Mansion: Dark Moon made him more closely resemble his original appearance, but with black shading around his eyes.
  • Your Size May Vary: In some games, he is the same size as a normal Boo, but in others, he's larger. In Dark Moon, he's an outright Sizeshifter.

    Dry Bowser
"So, you want to stick with us, huh? Eager to join our cause? Bwa ha ha ha!"

A skeletal version of Bowser. In his debut game, Dry Bowser was created in the first castle when Bowser was Stripped to the Bone after being dunked into a Lava Pit. Since then, he has made appearances as a separate character from Bowser, such as Mario Kart Wii and the Mario & Sonic series.

  • Background Boss: In New Super Mario Bros. 2, he attacks from the background in his second phase, just like regular Bowser.
  • Badass: Being reduced to a skeleton doesn't stop Bowser; if anything, it just makes him more powerful.
  • Bad Boss: In his final battle in Super Mario 3D Land, his shockwaves will not only hurt Mario/Luigi, they will kill any other enemy they touch.
  • Bad with the Bone: Just like Dry Bones, he has the ability to throw bones.
  • Benevolent Boss: In the 3DS version of Mario & Sonic at the London 2012 Olympic Games, he treats his Dry Bones sidekick more like a friend than a minion, affectionately referring to him as "Bony, old boy".
  • Bonus Boss: In Mario & Luigi: Paper Jam, at the end of the Battle Ring's Medley mode.
  • Dem Bones: He's a skeletal version of Bowser.
  • Dracolich: He's a giant, undead, fire-breathing toothy reptile.
  • Decomposite Character: And no, not because he's a skeleton. In his first appearance, he was an undead Bowser. In later games, Dry Bowser appears as his own entity. In Mario Party: Island Tour, Bowser refers to him as a "close family friend". And in the Mario & Sonic series, he assists Bowser and Eggman in their evil schemes. In Super Mario 3D Land, he's the major boss of the Special Worlds, and kidnapped Luigi.
  • Defeat Means Playable: Just like his living counterpart, if you defeat him in Puzzle & Dragons: Super Mario Bros. Edition, he will join your team.
  • Divergent Character Evolution: In Mario Tennis Open, he's a Defense-type, while his living counterpart is a Power-type.
  • Downloadable Content: Mario Kart 8's April 2015 DLC adds him as a playable character.
  • Evil Redhead: Just like his living counterpart, Dry Bowser sports the same fiery red hair.
  • King Mook: While normal Bowser is this to the Koopas as a whole, Dry Bowser is this to the Dry Bones, their skeletal counterparts. He even falls apart and reassembles himself like one in his debut appearance, and he shares their immunity to fire.
  • Make My Monster Grow:
    • He turns giant New Super Mario Bros. 2, courtesy of the Koopalings' magic.
    • In Mario Party 10, after Bowser gets thrown into the lava at the end of the first phase of his boss fight, he reemerges as Dry Bowser and becomes giant.
  • Nobody Calls Me Chicken: In the DS version of Mario & Sonic at the Olympic Winter Games, Blizza, one of the Snow Spirits, accuses him of being too afraid to face the heroes. He doesn't take it well.
    Dry Bowser: Too bad I'm through talking to you. Good bye!
    Blizza: Dry Bowser! I bet you're just scared of us!
    Dry Bowser: What did you call me?!
    Blizza: You're just trying to get out of challenging us, aren't you?
    Dry Bowser: Wh-What?!
    Blizza: Hah! I knew it! Wow, wait till everyone finds out about this...
    Dry Bowser: Ggggrah! You shouldn'ta said that! Nobody makes fun of Dry Bowser! Nobody!
    Blizza: A-ha! So you'll accept our challenge?
    Dry Bowser: Why you—! Fine! I'll see you on the field of battle— A Curling Bowling battle!
  • Nonmammalian Hair: His skin was burned off, but his hair remained intact.
  • Promoted to Playable: Mario Kart Wii is his first playable appearance.
  • Recurring Boss: In Super Mario 3D Land, where he shows up in the special worlds for three boss fights. Unlike regular Bowser, he does not employ fakes, all three fights are against the real deal.
  • Red Eyes, Take Warning: If being a skeleton of the Big Bad of the series isn't scary enough, he also sports these to make himself more terrifying.
  • Technicolor Fire: His fire breath is blue, as opposed to his living counterpart's orange. His fire breath was still orange in his debut, though.
  • Tennis Boss: In Mario Party: Island Tour, the objective of his boss fight is to knock the bones he throws back at him with a hammer.
  • True Final Boss:
    • In New Super Mario Bros. 2, he's the boss of World Star, which is unlocked after beating the regular final boss in World 6 and requires 90 Star Coins to enter.
    • Happens again in Puzzle & Dragons: Super Mario Bros. Edition, where he is the boss of Special World 8.

  • Co-Dragons: With Boom Boom.
  • Dark Action Girl: One of the few known female members of Bowser's army.

  • Helpful Mook: The boomerangs she throws can be jumped on, and will give you a coin if you do so. In a less deliberate (but much more influential) example, she can be manipulated into giving you a fortune of 1-ups if you perform a certain trick.
  • Hidden Depths: The commentary in the official soundtrack for 3D World states that she wants to be refined and elegant, but is prone to losing her temper. Her battle theme is meant to reflect this.
  • Meaningful Name: Her Japanese name can refer to a state of fury, which fits with the short temper she's said to have.
  • Ninja: She has this schtick in 3D World; not only does she throw around a shuriken, but she uses hand seals to disappear in a puff of smoke and split into an mob of shadow clones.
  • Recurring Boss: Fought multiple times in both 3D Land and 3D World. She's only the third female boss to appear in more than one game (following Wendy and Kammy Koopa).

  • Jump Scare: It comes alive whenever the player runs near it or jumps on top of it.
