BEWARE OF UNMARKED SPOILERS
Season 1
- Everything about Obake. An Evil Genius mastermind who stays in the shadows, and whom the team doesn't know the existence of until mid-season... while Obake knows every single detail about them. The idea of someone stalking you while you're oblivious to it is pretty creepy.
- Just look at the Slasher Smile he gives in the picture above. Enough said.
- His principal obsession with Hiro, a 14-year-old boy, is disturbing too. He sees his younger self in him, yeah, but he also manipulates and tests him from the shadows, going as far as creating a hologram of his dead brother. Yikes.
- The way he strokes Noodle Burger Boy's chin
◊ is quite uncomfortable to watch. - His Evil Plan: destroying the city and rebuilding a "perfect one" in his image, for a world of science and learning.
- What makes it disturbing, is that his Childhood Brain Damage refrains him from seeing right from wrong. He has no idea how crazy this is.
- Or worse. He knows how bad it is, but goes through with it anyway because there are no limits to hold him back.
- His fate. Being crushed by rocks and drowning can't be a pleasant way to go.
- What makes it even more bloodcurdling is that he chose to accept his demise after his plan failed instead of getting Baymax's help. What Do You Mean, It's for Kids?
- Granville hopelessly seeing her former student lose himself to villainy and feeling guilty about it.
- Turns to Tear Jerker after what happens to him at the end of "Countdown To Catastrophe".
- In "Baymax Returns", Yama tries to throw people off buildings. One of them being Hiro, a 14 year old child.
- What makes this even more chilling, is that no one has any idea that Hiro is between Yama's clutches. Aunt Cass and his friends could've lost him and learned it too late.
- Dibs transforming into Globby is quite chilling. He just sees an enormous gelatinous form envelop him and literally becomes him. This means, Dibs's bones and muscles are gone and he's now 100% glob. Hearing his screams and seeing the shadows on the wall showcases us Dibs went through a lot of pain during that transformation.
- He even admits he forgot how much it hurt in Season 2.
- In "Mr. Sparkles Loses His Sparkles", one of Mr. Sparkles' obstacles in his course is a giant blender that GoGo almost falls in. Not that Mr. Sparkles minds.
- On multiple occasions, Momakase tries to slice her opponents in half with her Absurdly Sharp Blades.
- Noodle Burger Boy after Obake kidnaps and hacks into his code. One who was once a cheerful fast food mascot turns into a creepy henchman while retaining his cheerful personality.
- Can detect your every movement before you even do them, which makes him next to impossible to defeat.
- His creepy shining red eyes before shooting his lasers at you. See for yourself.
- His Evil Laugh: a robotic monotone "hee-hee" giggle.
- Though it happened off-screen, Karmi gets kidnapped by Momakase and Bound and Gagged in a dark abandoned room, her only hope being Big Hero 6. When Hiro finds Karmi on the camera screen, she's got her eyes closed. She must've been terrified out of her mind.
- In "Obake Yashiki", after visiting a haunted fun house, the gang (sans Hiro, who sees Tadashi, and Baymax) see their worst fears right before them. It can't be fun.
- Hearing Obake's voice come out from the Tadashi hologram's mouth is definitely disturbing.
- Baymax under the influence of Obake's chip somehow comes off as worse than his berserker phase in the movie, as he can still talk but the things he says in his characteristic voice and cadence are just chilling. The below sentence makes Hiro comply immediately.Baymax: Resisting will result in further injury.
Season 2
- The Big Bad of Season 2’s first arc: Liv Amara; a kind Benevolent Boss by day, a ruthless sociopath by night.
- She blackmails people into funding her nefarious projects and mutates them into monsters in return.
- Depending on the case. Villains such as Momakase and Mr. Sparkles are 100% willing to be mutated. However, the same cannot be said about Orso Knox and High Voltage...
- Literally no one, except for the main heroes, knows of her true colors. Not even Professor Granville.
- She tries to have Karmi and Hiro killed by an unstable monster!Knox by freeing him from his cell after Karmi and Hiro get too close to her plans.
- The worst part? She still acts like Karmi's friend, and the latter has no idea her so-called "bff" was the reason she almost got killed. With Friends Like These...
- Just how realistic of a psychopath she's portrayed in a children's show.
- She blackmails people into funding her nefarious projects and mutates them into monsters in return.
- High Voltage's mutations thanks to Liv Amara in "Something's Fishy". Just when they wanted a normal life, they got forced by Liv into this mess...
- The first signs of their mutation. They get hungry for fish... which they eat whole. The truck driver they steal the fish from is horrified and runs away screaming.
- Their transformation into eel-like monsters. They are visibly distressed and horrified by their monstrous appearances. Juniper panics and goes to her mother for comfort, who while trying to comfort her daughter, is just as terrified as her.
- Their final transformation into Animalistic Abominations. They look more eel than human, and are kept in Liv's aquarium as pets. Talk about disturbing.
- Chris breaking into Honey Lemon's lab to steal a sample of Globby in "Nega-Globby!". He hides in the shadows until a security drone comes in, and gets the jump on it by shoving his arm straight through the robot. He then steals the sample he came for. The creepiest part is that the whole time Honey Lemon is sleeping in the room.
- If you thought the series would lighten the Body Horror on the monster transformations if they happened to a main character, think again. Karmi’s - who is to note a young teen like Hiro - transformation is at least as horrific as Ned Ludd’s if not more. Much of it is covered by a half-Gory Discretion Shot, but at one point her jaw detaches and twists into something resembling a clawed mandible onscreen.
- There's also Hiro, suddenly stuck in an enclosed space with a feral ten-foot-tall monster with claws that can rip through stone. He quickly goes from trying to help Karmi to trying to run for his life but doesn't get far...
- He also would have suffered the same fate as Karmi if not for the real Liv Amara surviving.
- In "Fear Not", when Wasabi is hired to fill in for an absent teaching assistant, Hiro and Honey Lemon use Simmax, their new training room, to simulate the classroom, to help him get over his fear of public speaking. But when the students are simulated, they glitch out so only their eyeballs, tendrils and all, are visible, and come straight for him, never blinking. It's quite disturbing, and Wasabi’s reaction is justified.
- "Legacies" shows that Chief Cruz was within a hair's breadth of a full Face–Heel Turn. The sting operation he planned to trap Big Hero 6 was not just illegal, but outright ruthless—taking advantage of their sympathy for others, and there was no illegal activity for him to arrest them on. Sure, Cruz was a jerk, but this is a whole new low that almost made him as bad as the bad guys.
