Yama & co.
Mr. Yama
"Yama"
"Who's next? Who has the guts to step into the ring with Little Yama?"
A sleazy underground bot-fighter and the boss of a crime ring.
- Acrofatic: In "The Bot Fighter" episode of the series, the team finds footage of Yama taking samba dance lessons, and he's quite talented at it for someone who has the girth of a sumo wrestler.
- Arch-Nemesis: Appears to be Hiro's.
- Ascended Extra: He's a minor threat to Hiro, and quickly overshadowed by Hiro deciding to attend SFIT in the film. He's a recurring villain in the TV Series.
- Asian Rudeness: A smug and arrogant Japanese brute.
- Batman Gambit: In "A Fresh Sparkles", he kidnaps Mr. Sparkles after escaping from jail (whom he holds a grudge for incarcerating him twice), steals a painting using Sparkles' chicken airship and leaves it on top of abandoned warehouse. It leads to Big Hero 6 thinking Sparkles was a Fake Defector and are lead directly into Yama's trap. Counts as a Smart Ball from Yama's part, who is usually the clueless easily manipulated one.
- Benevolent Boss: Despite being a Jerkass, he treats his thugs fairly well. If you exclude the one thug Yama used as a Human Shield.
- Brought to You by the Letter "S": His jacket has the character for his name in Japanese, "山", written on the back.
- Butt-Monkey: From getting beat up by Megabot, to being arrested and constantly pushed around and beaten by Big Hero 6 and Momakase in the series, Yama clearly has no luck.
- The Chew Toy: Something frustrating always seem to happen to him whenever he's on screen. Since he's a bad guy, it's quite funny to watch.
- Creator Cameo: Voiced by the film's head story writer, who came back to voice him in the series.
- Demoted to Extra: Gradually loses importance over Season 1 and only appeared in one episode so far in Season 2.
- The Dragon: In the series premiere, he's Obake's main lackey. After his failure to retrieve Granville's paperweight, it appears that Yama no longer works for the villain.
- Evil Counterpart: Though not necessarily evil per se, he was created to be a sort of "what if" possibility for Hiro; namely, what he might wind up being like if he continues down the road of hustling back alley bot-battles.
- Evil Genius: Genius is a big term considering that Yama is prone to a few clueless moments, but he was able to build hundreds of copies of Baymax's exoskeleton most probably by memory.
- Evil Versus Evil: He and Momakase have history, and they're not each other's favorites.
- Fat Bastard: He's as unpleasant as he is huge.
- Fat Comic Relief: A villainous example. Despite being a fairly dangerous thug, his Butt-Monkey status brings quite funny moments both in the movie and series.
- Fat Idiot: Downplayed. Yama is far from being a total imbecile (see Genius Bruiser and Evil Genius above), yet he still has some moments where he's easy to fool and is the butt of many jokes.
- Frame-Up: Look at Batman Gambit above.
- Genius Bruiser: While he prefers to throw his own weight around, he is a bot fighter who likely created Little Yama. He also uses a robot army in the TV series to distract the police from his actual goal of stealing a valuable alloy from the dean's office.
- Harmless Freezing: On the receiving hand of Honey Lemon in the series' pilot.
- Hidden Depths: Who would've thought that a hardened criminal like Yama actually enjoys taking samba classes?
- High-Altitude Interrogation: Does this twice in the premiere, the second time to Hiro.
- Hypocrite: He dismisses Hiro's request for a rematch, saying that nobody likes a Sore Loser. After his bot is defeated, he and his goons decide to beat Hiro up.
- Irony: Played for Laughs in the Cold Opening to "El Fuego". He creates a New Mega-Yama to break him out of prison, but the robot is distracted and defeated by Big Hero 6 before it can do much damage. Yama, oblivious to all of this, exclaims "Hurry, New Mega Yama! Before Big Hero 6 shows up!"
- Jerkass: He is very condescending towards his opponents.
- Knuckle Cracking: Delivers the neck crack variant as he and Hiro face off prior to their first bot fight.
- Laser-Guided Karma: Gets arrested along with all of his thugs, everyone that showed up at the bot fight, and the Hamada brothers.
- Malicious Misnaming: He purposefully calls Hiro "Zero".
- Meaningful Name: "Yama" is Japanese for "mountain", which is a pretty apt description of him.
- Oh, Crap!: Has one when Obake calls him after Yama failed to retrieve an item for him.
- Only One Name: It's unknown whether "Yama" is his birth name, or a nickname derived from a surname like "Yamamoto" or "Yamasaki". "Yama" is also a surname in itself, which could also indicate he has a Last-Name Basis.
- Out of Focus: Over the course of Season 1, his role decreases in favor of the new antagonists introduced in the series, and he isn't part of Obake's inner circle by the finale. By Season 2, Liv Amara's picture replaces his in the intro.
- Sealed Evil in a Can: In the beginning of the movie, he's arrested with the rest of his goons. Though by the series, it's implied Obake might've released him from jail so he could work for him. He's arrested again in "The Fate of The Roommates" after being backstabbed by Mr. Sparkles, and ratted out by Sparkles again somewhere in Season 3 before he escapes jail in "A Fresh Sparkles".
- Smug Snake: He's an arrogant brute who believes he's the best bot-fighter around.
- Sore Loser: He gets mad at Hiro for defeating him at a robot fight and orders his mooks to beat him up as retribution.
- Starter Villain: He's the first antagonist Hiro faces, both in the movie and in the series.
- Sumo Wrestling: His design is obviously inspired from sumo wrestlers (he definitely has the girth of one). Early concepts of the movie had Yama actually be a sumo wrestler that was Yokai's right-hand man and The Brute.
- This Cannot Be!: His reaction when Hiro's megabot annihilates his Little Yama bot.
- Villain Team-Up: He has joined forces with Obake in the early episodes of Season 1, and in Season 2, with Mr. Sparkles. Eventually subverted as in the end, the partnership broke because Status Quo Is God.
- Would Hurt a Child: Yama was about to have his thugs beat up a 14-year-old. In the series, it's implied that his High-Altitude Interrogation of Hiro was going to end via the street...
- Yakuza: Yama has partaken in such San Fransokyo criminal activities as illegal underground bot fighting, thievery, loansharking, and murder.
Gangsters

- Badasses Wear Bandanas: One of Yama's main thugs wear one.
- Beard of Evil: Basketball Shirt and Tank Top have these.
- The Brute: All of them.
- The Chew Toy: Each time they're on screen, they get beaten in some way. Since they're bad guys, it's satisfying to watch.
- Co-Dragons: Are these to Yama.
- Human Shield: Yama uses one of his knocked-out thugs to protect himself from Honey Lemon's chem-balls in "Baymax Returns".
- Mooks: Yama's personal ones. In the series, they basically exist to get their asses kicked by Big Hero 6.
- No Name Given: We don't know their real names. Two of the henchmen trio are credited as "Basketball Shirt" and "Tank Top" in the series.
- Terrible Trio: While Yama has many mooks working for him, the ones pictured from the movie are his main henchmen.
- Undying Loyalty: To Yama. They follow his every orders.

The Ringleader
"Beat it, kid. House rules: you gotta pay to play!
The ringleader in the bot-fighting ring and Yama's assistant.
- Aloof Dark-Haired Girl: Is a tough, scornful criminal with dark hair.
- Asian Rudeness: She appears to be Japanese, and is definitely condescending and rude to young botfighters like Hiro and Trina.
- Badass Fingersnap: Does this to order brutes working for Yama to kick botfighters (in that case, Hiro) out.
- Boots of Toughness: She wears leather high-heeled boots.
- The Bus Came Back: After briefly appearing in the movie's intro, she is brought back in "The Bot-fighter".
- Combat Commentator: Her job in the bot-fighting underground. Though she only comments before and after the fight, and never during.
- Composite Character: A meta example; her final movie character design has parts of the scrapped Fujitas: the physical appearance and the hair chopsticks of the green fujita, the blue fujita's eyepatch and the pink fujita's hair flower.
- The Dragon: To Yama.
- Dragon Lady: A tough, aloof Japanese woman who engages in San Fransokyo's criminal underworld and has a job as the botfights' ringleader.
- Eerie Pale-Skinned Brunette: Yama's antagonistic assistant with dark raven hair.
- Evil Eyebrows: Long, thin and dark arching eyebrows, who are even exaggerated in the series' more geometric style.
- Evil Is Hammy: Though it's part of her "ringleading" act.
- Excessive Evil Eyeshadow: She's got bright purple eyeshadow. Though it's more subtle in the movie and more prominent in the series.
- Eyepatch of Power: Wears a black eyepatch over her left eye. It's unknown if it's simply to look intimidating or due to an Eye Scream.
- Geisha: Her character design is inspired from this. Justified, since originally she was supposed to be in a trio of criminal geishas.
- Jerkass: She seems to be condescending towards younger bot-fighters, as she mocked Hiro with everyone else in the movie, and did the same treatment towards Trina.
- Lean and Mean: She's tall, slim and a criminal in the bot-fight underworld who serves as the ringleader.
- No Name Given: Credited as "Ringleader" in the movie, and "Yama's assistant" in the series.
- Prim and Proper Bun: How she styles her hair, though she isn't as "prim and proper".
- Purple Is the New Black: She's a villain and has magenta-purple lipstick, purple eyeshadow, wears purple shorts and has a purple flower in her hair.
- Raven Hair, Ivory Skin: A Japanese woman with pale skin and black hair.
- Repulsive Ringmaster: A non-circus variant. She's a tough, condescending woman that is in charge of the illegal bot-fights in Good Luck Alley.
- Reused Character Design: A meta example. She was originally supposed to be part of "The Fujitas", a trio of criminal geisha sisters working for Yokai, where she had bangs instead (another geisha had the Eyepatch of Power). But as the movie's storyline changed in writing, The Fujitas were dropped and her design was used as a cameo for the ringleader in the final movie instead.
- Sleeves Are for Wimps: Wears an orange tank top.
- The Smurfette Principle: She's Yama's only female minion.
- Statuesque Stunner: She's a tall woman with long legs and is without a doubt beautiful.
Bot-fighters
Trina
Trina
Trina's human body (Click hereto see her second human body)
Trina's mecha body
"Don't you get it, Hamada? I survived to carry on father's legacy! To fulfill his dream!"
A young bot-fighter, who turns out to be Obake's robotic daughter.
- Affectionate Nickname: Noodle Burger Boy calls her "sis".
- Aloof Big Sister: Though she does care about Noodle Burger Boy and is protective of him, Trina has her moments where she's harsh and dismissive of him. It's justified since Noodle Burger Boy annoys her while she works.
- Arc Villain: Of the second season's two-part finale, "Legacies".
- Artificial Family Member: She's Obake's robotic daughter. While he mainly built her to lure Hiro, he seems to see her as more than just an artificial intelligence, as seen when he hugs her and runs his hand through her hair in a fatherly way.
- Artificial Human: What she turns out to be. She's an overly-realistic teenage girl android created by Obake.
- Avenging the Villain: Trina's goal in the second season is to avenge Obake's name after he got defeated by Big Hero 6.
- Ax-Crazy: As of "Legacies", Trina becomes just as unhinged and bloodthirsty as her father.
- Badass Longcoat: She wears a black longcoat in the Season 2 finale not only to firmly establish her as the heir of her father's name, but also as the main threat of said finale.
- Becoming the Mask: Downplayed. While Trina always set up Hiro to go back to botfighting (due to her Undying Loyalty to Obake), she's shown to have really considered him her friend and her plea to stay in it with her seemed genuine.
- Beneath Notice: Hiro never considered the possibility of her being involved with the thefts involving bot-fights because she always lost. He later realizes this was intentional.
- The Big Gal: After her upgrade.
- Big Girl, Little Guy: The Big Girl to Noodle Burger Boy's Little Guy.
- Big Sister Instinct: In "Internabout", Trina spends most of the episode equipping herself to help her "brother", Noodle Burger Boy, even though it's obvious she finds him annoying.
- Bitch in Sheep's Clothing: Seems to be a nice, friendly girl towards Hiro in her debut episode. Turns out this whole time, she was the one behind the bot thefts and drops her nice friendly façade when Hiro unmasks her. Also important to know Obake programmed her to lure Hiro back into the botfighting world so he'll be out of his way. In "Legacies", she also managed to get Krei to make her the head of a secret robotics department, after only one meeting.
- Boyish Short Hair: In "Legacies", Trina cuts her hair in a short side fringe to look more identical to her father.
- Brainy Brunette: Enforced. Obake built her to be a competent and highly-realistic android and gave her brown hair.
- Collector of the Strange: She collects what Obake calls "trinkets", which derives from her programming and annoys him.
- Cool Big Sis: Noodle Burger Boy sees her as such. He even calls her "sis".
- Costume Evolution: Her attire changes a lot over the course of 2 seasons. In Season 1, Trina wears normal teenager clothing. In Season 2, after Obake's death and her previous body's malfunctioning, Trina builds a new mecha body which is much more powerful and useful when she's in the middle of the action. By "Legacies", Trina has a backup human body that she used to become affiliated with Krei Tech, which wears a tailored suit and grey sweater that copies Obake's look, grounding her as the finale's main villain.
- The Cracker: Can hack into bot-fighter's robots and use them to commit thefts and blame the bot-fighters for it. "Legacies" also shows her using Obake's hacking code and impersonating him to throw off Big Hero 6.
- Curb-Stomp Battle: She goes through the team like they're nothing thanks to her new update in "Internabout".
- Cute and Psycho: She might be a pretty teenage girl at first glance, but she's actually the evil android daughter of a Mad Scientist who's devoted to him and keeping his legacy alive.
- Creepy Blue Eyes: Just like her father, she has those.
- Daddy's Girl: Definitely towards Obake. She sees him as her father and loves him deeply, and Obake cares about her in return.
- Daddy's Little Villain: She's Obake's android daughter, who is loyal and devoted to him. In return, Obake is caring towards her and seems to see her as more than just a robotic minion like Noodle Burger Boy. When Obake dies in the ending of Season 1, Trina vows to avenge her father, defeat Big Hero 6 and destroy the city in a robotic revolution in his honor.
- Dark Action Girl: Post-updated body, Trina is strong and curb-stomps the team like it's no biggie.
- Deadpan Snarker: Has a sarcastic streak and a sharp tongue that only Obake is safe from.
- Delinquent Hair: Gains a mohawk in Season 2, before changing her hair in an emo-style undercut similarly to her father's when he was a teenager, along with red streaks like his adult haircut.
- The Dutiful Daughter: She'd rather focus on avenging her father than deal with her "little brother" Noodle Burger Boy's annoying antics.
- Eerie Pale-Skinned Brunette: In "Legacies" where she dyes her hair black to resemble Obake more. It brings out her pale complexion.
- Even Evil Has Loved Ones: She cares a lot for her "father" Obake and her "little brother" Noodle Burger Boy.
- Even Evil Has Standards: "Lie Detector" shows that Trina seems a tad disturbed that supervillains "turn into monsters these days".
- Evil All Along: She appears to become Hiro's new bot-fighter friend, but all this time, she was the one behind the bot heists.
- Evil Costume Switch: Although already an antagonist, her new look in Season 2 is much more villainous and anchors her as a more dangerous threat to Big Hero 6. She gets another one in "Legacies", where she copies her father's look by dying her hair black with red streaks, to ground her as Obake's living legacy.
- Evil Genius: Like father, like daughter. It's justified since being a creation of her father's, Trina possesses all the resources to recreate Obake's inventions the same way he did.
- Evil Wears Black: She sports a black trenchcoat in "Legacies".
- Facepalm: Her reaction to Noodle Burger Boy trying to destroy Baymax and Hiro with ketchup.
- Fille Fatale: Downplayed. Trina is very flirty with Hiro, considering they're about the same age, but what makes it disturbing is how Obake programmed her as such in order to lure Hiro back into bot-fighting. She basically acts like a Fille Fatale Spy.
- Final Boss: She's the main antagonist of Season 2's finale.
- Foolish Sibling, Responsible Sibling: The Responsible Sibling to Noodle Burger Boy's Foolish Sibling.
- Girliness Upgrade: Inverted. Her new design in Season 2 looks far more tomboy-ish compared to her original Season 1 look.
- Girly Girl with a Tomboy Streak: Though it might be how Obake programmed her, Trina wears a pink shirt, jeans with stars and has long hair, while being simultaneously into bot-fighting and has an overall "teen rebel" look and personality. By Season 2, she goes more into tomboy territory when she upgrades herself and cuts her hair.
- Hack Your Enemy: Her speciality during bot-fights.
- Honey Trap: A G-Rated version. Trina is quite flirty with Hiro in her debut episode, but turns out it was simply to lure him back into the botfighting world as it's what Obake programmed her to do.
- I Have Your Daughter: She jumps at the opportunity to kidnap Megan and threaten to hurt her so that her father and his troops stay out of her tail.
- Important Haircut: Cutting her long hair into a mohawk indicates her newfound role as a recurring antagonist. Later, she changes her hair similarly to how Obake's looked (black with red streaks) to cement her "Daddy's Little Villain" role in "Legacies".
- Ink-Suit Actor: She does look like a younger Christy Carlson Romano with blue eyes.
- Innocent Blue Eyes: Subverted. Seems to hint her friendly nature to Hiro at first, but turns out to be a case of Icy Blue Eyes as well as hinting her being Obake's "daughter", since Obake has Icy Blue Eyes as well.
- Jerkass Ball: Her treatment of Noodle Burger Boy in "Write Turn Here" was way harsher than usual, as it saddened him and she didn't seem to care.
- Lady in a Power Suit: In "Legacies", Trina wears a black tailored suit that resembles Obake's clothing when she reveals her plan to Hiro and her secret affiliation with Krei Tech.
- Like Parent, Like Child: Just like Obake, she's an Evil Genius with skills into robotics who takes a liking to Hiro. Though it's partially how Obake programmed her, Trina was shown from the beginning to develop her own personality and goals outside of it.
- Little Miss Badass: Combined with a mecha body, on top of that!
- Little Miss Con Artist: Similarly to Hiro in the movie, she pretended to lose in all her bot-fights. This permitted her to hack into her opponents' robots without them knowing and frame them for her thefts.
- Losing Your Head: When Hiro is taken to Obake's lair, he sees her head on a table. Becomes a Running Gag in "Internabout", where her head constantly falls off her neck. It pushes her to upgrade herself to a new body.
- Made of Iron: A literal example after her Evil Makeover.
- Madness Makeover: During the climax of "Legacies", Trina's face gets almost fully damaged after Megamax throws her on the other side of the city, with only her right eye remaining to make her look remotely human. When that happens, all of Trina's programmed sanity goes out the window.
- Mad Scientist's Beautiful Daughter: Trina is Obake's (robotic) daughter, and she has a pretty teenage girl appearance.
- Manipulative Bitch: Her goal from her very introduction was to make Hiro go back to bot-fighting in order for him to stay away from Obake's path. Though she seems to have actually cared about him the brief time they were friends.
- In "Legacies", she managed to get Krei to make her head of the robotics department after only one meeting.
- Meaningful Appearance: Wears these in Season 1 as part of her "teen rebel" look.
- Mini-Mecha: Her new body in Season 2 definitely counts as this.
- Meaningful Appearance: Her blue eyes foreshadow her tie to Obake.
- Meaningful Name: Trina comes from the latin "trena", which ties with the Holy Trinity. Over the course of two seasons, Trina has three different bodies: the teenage girl body, the mecha body and the human body who looks like Obake. Three different bodies who all embody one thing: Obake's legacy.
- Nice Job Fixing It, Villain: Turns out her whole goal about keeping Obake's legacy going was the key to her defeat, as Hiro was inspired to preserve another legacy instead: He copied Tadashi's chip and inserted them in the Buddy Guardians and thus, used Tadashi's legacy against Trina.
- Obfuscating Stupidity: Just like Hiro in the movie, she pretends to be a newbie at bot-fighting only to fool her opponents and hack their robots.
- Older Alter Ego: Trina makes herself an adult body so she can get a contract with Krei Tech to build new police robots as part of her plan.
- Pet the Dog: Sees Noodle Burger Boy as her little brother and is shown to be greatly protective of him.
- Pink Means Feminine: Wears a pink shirt in her initial look.
- Pulling Themselves Together: She's perfectly able to have her body parts (such as her head) detached from the rest of her body, since she is a robot. However, her head has difficulty staying in place, which pushes Trina to build herself a new, stronger body.
- Purple Is Powerful: Her mecha body has different purple highlights, and makes her a much more dangerous foe than she initially was with her android body.
- Purple Is the New Black: Seals her position as a recurring antagonist once she upgrades herself to a mecha body that is purple in color.
- Raven Hair, Ivory Skin: In the Season 2 finale, her jet black hair brings out her pale skin.
- Revenge: Her main objective in Season 2, after Obake's death.
- Ridiculously Human Robots: Until her Robotic Reveal where she opens her face, you wouldn't think for a second she's actually a robot due to how she behaves exactly like a human would compared to other robot characters.
- Robot Girl: Obake built Trina to look and behave exactly like a normal teenage girl in order to lure Hiro back into botfighting and out of his way.
- Robotic Psychopath: While she wasn't innocent in Season 1, she's much more active and dangerous in Season 2. Her goal is to create a robotic revolution and make her father's dream of having the city destroyed come true. It goes without saying that Obake's death didn't help her morality at all.
- Robotic Reveal: It turns out that she's a robot made by Obake, whom she considers her father.
- Sanity Slippage: Over the course of "Legacies", Trina becomes more and more unstable and goes completely ballistic towards the end.
- Shared Family Quirks: She does the same screen change hand motion Obake did.
- Siblings in Crime: With Noodle Burger Boy as of Season 2.
- Smart People Build Robots: Takes a robot to know how to build other robots, right?
- Techno Dystopia: Her goal in "Legacies". She wants to destroy humanity starting with San Fransokyo as it's what Obake dreamt of.
- Teen Genius: Is very skilled with building robots. Justified, since Obake programs her as such.
- Took a Level in Badass: Trina pre-update? Teenage girl body, constantly loses her head and can't do much. Trina post-update? Taller, stronger, Made of Iron and beats her opponents with ease.
- Undying Loyalty: To her father, Obake. She'd do anything for him, even after his death.
- Villainous Breakdown: She gradually becomes more and more deranged over the course of "Legacies".
- Villainous Crush: She appears to have one for Hiro, despite being an android and Hiro being human.
- Villainous Legacy: The whole point of "Legacies" is Trina wanting to keep Obake's legacy going through her, and destroy the city like her father dreamt of.
- We Can Rule Together: On two occasions:
- In "The Botfighter", it's more of a downplayed version of Trina trying to convince Hiro to stick to botfighting considering he loves it so much. When Hiro refuses, she creates a gigantic robot made of all the robots she hacked and makes it attack him while she escapes.
- In "Legacies", she asks Baymax to join her Techno Dystopia. When he tries to convince her robots are supposed to help humans, Trina does a 180° and orders him destroyed.
- We Used to Be Friends: "Legacies" indicates that Trina really did consider Hiro her friend despite her father's programming, as she tells Megan she and Hiro "used to be a thing".
- Wham Shot: In "The Botfighter", seeing her face open and revealing robotic insides.
- What Happened to the Mouse?: After being subdued by Hiro in "Legacies", we have no idea what happens to her. Since she is a robot and not a human, she is most probably deactivated rather than arrested.
- Woman Scorned: She's implied to really have had concrete feelings for Hiro in her debut episode, and she later blames him for Obake's death, which causes her to try and destroy him out of revenge.
- Would Hurt a Child: An interesting case considering she's programmed as a teenager. Nevertheless, she's an android that attempts to harm Hiro and threatens to kill Megan in "Legacies".
- Yandere: Constantly switches between being somewhat friendly and flirty to Hiro and reminding him of their former friendship, to attempting to kill him and his friends.
- You Killed My Father: Trina blames Obake's death on Big Hero 6, and vows to avenge her father by destroying them and the whole city in the process, as Obake planned to do.
Stan
A botfighter and acquaintance of Hiro back in his botfighting days.
Gus
A condescending self-proclaimed "professional bot-fighter".
Battle Bots
Little Yama
Little Yama
Appearances: Big Hero 6 | The Series
Yama's bot he uses in bot-fights competitions.
- Chainsaw Good: Little Yama has a circular saw that he uses to dismantle opponent bots.
- Curb-Stomp Battle: Not only does he submits other robots to this, he receives one from Hiro's Megabot.
- Cyber Cyclops: Has only one eye.
- Dark Is Evil: Yama's bot, who belongs to an antagonist, is black.
- Mighty Glacier: Due to his large stature, it's easy for smaller robots like Megabot to defeat him since it takes more time for Yama to get to control him.
- One-Steve Limit: A variant. Yama seems to love giving robots his name, considering he also gave it to Mega Yama.
- Power Pincers: Little Yama has a thick metal pincer that he uses to pin opponents down while he saws them in pieces.
- Samurai: Probably as part of the Japanese-American culture from the franchise, Yama seems to have incorporate samurai armor parts into Little Yama's design (ex: his helmet heavily resembles a samurai's).
- Replacement Goldfish: Got destroyed by Hiro in the movie and rebuilt in "The Bot-Fighter"... only to be destroyed again.
- Unskilled, but Strong: It goes without saying that Little Yama is a powerful robot, but other than its strength, once the opponent is faster than he is, Yama has difficulty catching up.
Mega Yama
Mega Yama
Appearances: The Series
A giant robot who serves as a mook to Yama.
- Abnormal Limb Rotation Range: He can turn his head 180°. Justified, since he's a robot.
- All Your Powers Combined: Mega Yama has a plasma launcher built by Wasabi, a liquefied undestroyable armor made by Honey Lemon that resists her chemicals and a magnetic levitation system built by GoGo based off her mag-lev disks that permits him to move faster.
- Ax-Crazy: Craves destruction.
- The Brute: To Yama.
- Create Your Own Villain: Trevor Trengrove got Wasabi, Honey Lemon and GoGo to build Mega Yama without them knowing, since Yama blackmailed Trevor into helping him or he'd reveal to the world he stole Wendy Wower's thesis.
- Cyber Cyclops: Like Little Yama.
- Dark Is Evil: The pre-update Mega Yama, anyway.
- Defeat Equals Explosion: After being defeated by vinegar and baking soda thrown inside his blasters, Mega Yama implodes.
- Giant Mook: Serves as one to Yama.
- It Can Think: Contrary to Little Yama, who is controlled by Yama, Mega Yama is self-sentient.
- Killer Robot: Programmed by Yama to be this.
- Luckily, My Shield Will Protect Me: He has a giant indestructible shield.
- Made of Iron: A literal case. Wasabi, GoGo and Honey unbeknownst to them built Mega-Yama to be impossible to destroy.
- Meaningful Name: "Mega" means "big".
- Mecha-Mook: A Giant Mook of Yama in the form of a mecha robot.
- Mini-Mecha: He's basically a bigger form of Little Yama. Yama is even riding on his back.
- One-Steve Limit: A variant. Yama seems to love giving robots his name, considering he also gave it to Little Yama.
- Real Men Wear Pink: Due to the gang unwillingly helping Yama through Trevor Trengrove build Mega Yama, Honey Lemon built him an indestructible armor that is pink. His color doesn't make him less dangerous.
- Red Eyes, Take Warning: When his eye turns red, watch out.
- Samurai: Like Little Yama, Mega Yama has a samurai helmet.
