In the most recent episode (ep 111), in a flashback from when he was a child,, Shigaraki's quirk accidentally activates as he is petting a dog, who dies graphically. It's pretty upsetting and they show the aftermath a couple of times before moving on from the scene.
The hero killer stain stabs people (mainly heros) to kill them. I haven't watched after season 2 but read some of the manga so take this as you will :)
Todoroki's abusive father tries to convince him that his mother, whom he drove to madness, was a bad person, and he's protecting him by sending her to the mental ward, even though he's the reason she went mad in the first place.
A mother gives up her daughter at one point, a child is terrorized by his father and there is a lot of child abuse from parents of a main character (beatings until he vomits, scalding water poured on him, etc).
Todoroki was put through very harsh training as a child, and at one point his mother threw boiling water at him. This has affected him greatly, even as a teenager.
Also worth noting: in the manga, a major villain (Overhaul) abuses a 6-year old girl while posing as her "father" figure.
Shigaraki and Dabi, who were abused as children, both become psychotic terrorists who want to destroy and kill everything. Dabi especially wants to torture his own brothers to death despite being emotional support through his abuse
No animal abuse occurs on screen. However, Nezu (a sentient mouse with a Quirk and the principal of the school) was reportedly experimented on in the past, and it caused him to develop a sadistic side (which we see during his fight with Mina and Denki).
Although there is a character called Hound Dog which quirk makes him have the appearance of a rabid dog, he is pretty human and doesn't really fight other dogs.
One episode involves Present Mic getting assaulted by a group of bugs travelling from underground, and they end up covering his entire body. It's not extremely important, so skipping this particular scene is optional.
Yes, people are restrained all throughout the series on many instances.
Some examples are Bakugou in the first three seasons, Eri in the fourth season, and not to mention some UA training exercises involve restraining people. Villains and criminals are also restrained constantly.
Minoru Mineta regularly sexually harasses his female classmates-he makes inappropriate comments about them, tries to peep on them whenever possible, and has groped them more than once. Unsurprisingly, a LOT of people hate him, and what doesn't help is that it's played for laughs and he hasn't been expelled for his behavior (yet).
Tsu holds Mineta’s head underwater in Season 1 after he grabs her breast. She does not do this with intent to kill him or knock him out and releases him after a few seconds.
Midnight emits a toxin that quickly causes who ever breathes it in to fall asleep. A minor villain in Season 3 has a similar quirk, however it’s more dangerous and causes dozens of people to be hospitalised.
Aizawa is pressed to the ground by a strong enemy holding his head down. He suffers injuries and is ultimately fine, but at the time there is the threat of head squashing.
Nobody is buried alive on screen, however, Shirakumo Oboro died in rubble prior to the canon timeline, it would be safe to infer that he was buried alive in the rubble, so to speak.
Yes, the character Re-Destro's lungs are injured by Edgeshot, Shemage attacks someone's lungs with fungal spores, and All For One pulls out one of Best Jeanist's lungs.
*Manga spoilers - Overhaul Arc*
Overhaul uses his quirk numerous times on a young girl to "reassemble" her after depleting her body through using her quirk to develop a drug.
At least one shot of Hagakure (15 - 16) is sexualized, it’s in the dorm episode. Sexual feelings are delved into and the majority of characters are teens so YMMV, how objectified they are is debatable but there is sensual content (especially whenever Mineta gets involved).
Crust dies protecting Eraser from Shigaraki’s decay shockwave. Bakugo jumps in front of an attack for Deku and gets stabbed through the gut, he survives. Also in general Deku has very little care for his own well-being and puts others above himself to a destructive extent. This culminates in Season 6 where he runs off on his own and works to the point of exhaustion and almost gets himself killed and even then, still pushes others away, worrying they’ll get hurt instead
Shigaraki kills his entire family prior to the events of canon due to a quirk accident, and Todoroki Shoto's older brother Toya is assumed to be dead until villain Dabi reveals he is in fact Todoroki Toya.
Bakugo vomits when he gets punched in the stomach by All Might during the Exams arc. It's definitely not depicted as sparkly rainbows that time, both in the anime and manga.
Additionally a younger Todoroki and Shigaraki are seen vomiting in flashbacks.
There is some audible bone cracking, and there are many screams of pain throughout the series. I'm not sure whether this counts, but as someone who finds it upsetting to hear people suffer, I thought it's worth mentioning.
Just because the show is about police and heroes doesn’t really automatically mean that it shows copaganda. Yes, it does show it in a way, but it also does show how corrupt some heroes can be. For example, Endeavour being the second best hero and abusing his wife/kids.
No characters are canonically revealed to be autistic though admittedly some could be perceived as autistic by fans, but I thought it was worth mentioning that a lot of characters get restrained, which may be a trigger for some autistic viewers.
Ymmv. Twice is a villain with D.I.D although he was already violent and evil before developing it and his regular personality is just as violent as his split one - the main thing it does is make him say contradicting statements or the opposite of what he means.
Several characters’ quirks are dependent on their calorie intake and there are scenes showing them binge eating for that purpose. It’s not a mental health issue for those characters, but watching them eat like that could be triggering for certain people.
During the Yakuza ark one of the villains controls the ceiling, walls and floor of a building. I have personally felt this scene to be quite claustrophobic.
One of the main villains has a tic that results in him scratching his neck. The more upset he gets, the more he scratches. There are a couple shots that show red lines, depicting that he's hurt himself. Though not cutting in the usual way, I'd definitely still be wary.
Theres a scene in the very first episode where the main character is told to "take a swan dive off the roof", other references of suicide have likely been mentioned throughout the series but i cannot cite them directly
Yes and no, because according to Japanese standards for anime, all strobe-like effects that have the potential to cause seizure already have a seizure filter over them.
At the start of Season 3 Episode 20, The opening scene features All Might and Deku directly speaking to the audience to say that this episode is a side story. The segment ends with all might saying “Now start those opening credits” which play immediately after this statement.
There is a brief repeated detail of the first baby being born with a Quirk, but it doesn't show any actual childbirth, you just see the baby in the hospital
As many people have said there is a villain character called Mange who is a trans woman. She and her friend who is also trans are shown to be overly dramatic, muscular, and hairy which are all harmful stereotypes. There is a leopard hero that wears dresses as a part of their uniform who also displays the same qualities. Almost all of the characters in the show except the villains misgender or explicitly point out their clothing. (The leopard hero gets the most comments regarding their choice in clothing since Mange is often seen in pants) Honestly as a trans person myself I feel like these characters are written in as jokes especially considering Mange gets graphically killed. This is a great show but it can be a little hard to watch at times so please keep this in mind beforehand and stay safe.
Himiko Toga uses the depraved bisexual stereotype. Also there’s a student in Class 1-A who, while not identified as being black, has the stereotypical oversized lips
There is zero incest undertones in AFO and his brothers relationship. I have no possible idea what the other comment is referring to. Their interactions are uncomfortable on the basis that AFO tortured his brother and forced a quirk on him for the sake of proving a point, not because of any underlining incestial feelings
Anything nude is not drawn or shown as actual nudity - for example, when Toga goes back to her real form she's shown as a whitish silhouette, no parts can be seen. So there is nudity implied but nothing depicted true to life.
In season 5 there is a flashback to Tomura Shigaraki's backstory where he is homeless and being ignored on the streets. He is found by All For One and taken in, though
No but if your worried about santa being spoiled maybe this show isn't for you, if your child is watching i feel like them believing in santa wont really muster the same innocence after this.
MANGA SPOILERS ///
290 onwards
In the manga Hawks prevents a near car crash although it doesn't crash it can be upsetting to see.
In chapter 311 ? I wanna say All Might almost crashes his car but gets out in time before he crashes and then is attacked.
