Quirk: Decay, All For One

Rank: S

"You heroes pretend to be society's guardians. For generations, you pretended not to see those you couldn't protect and swept their pain under the rug. It's tainted everything you've built. That means your system's all rotten from the inside with maggots crawling out. It all builds up, little by little, over time. You've got the common trash, all too dependent on being protected. And the brave guardians who created the trash that need coddling. It's a corrupt, vicious cycle. Everything I've witnessed... this whole system you've built has always rejected me. Now I'm ready to reject it. That's why I destroy. That's why I took this power for myself. Simple enough, yeah? I don't care if you don't understand. That's what makes us... heroes and villains."

The series' main antagonist and leader of the League of Villains, a jaded and irritable young man who wants to destroy society itself. He was raised by All For One, the villain who crippled All Might, and groomed to be his successor. "Tomura Shigaraki" is an alias, and his true name is Tenko Shimura, the grandson of All Might's mentor Nana Shimura.

His Quirk, "Decay", allows him to destroy anything he touches provided all five of his fingers are in contact with the object, befitting his desire for destruction. He is later given the original All For One Quirk, letting him wield multiple other Quirks simultaneously.


    open/close all folders 

    A - E 
  • Abusive Parents: His father, Kotaro, would lock Tenko out of the house when he misbehaved, and would keep him out there until he apologized. He also physically beat Tenko once when his buttons were badly pushed. Much of this abusive, or all of it, is centered around Kotoro resenting heroes after Nana Shimura left the family for their own protection.
  • Accidental Murder: In his Traumatic Superpower Awakening, he does this to his entire family and his dog. Subverted with his father, who he killed fully intentionally for all abuse he got from him mentioned above.
  • Achilles' Heel: Downplayed, but once Shigaraki manages to unlock the full power of his Decay Quirk during his fight with Re-Destro, he's able to now use the disintegration effect with each finger individually, allowing him to break free of Re-Destro's grip by partially decaying his fingers with his maimed hand, but he still seems to need all five fingers on one hand in order to unleash the full power of Decay in an AOE wave transmitted through the ground. Accordingly, having lost three fingers on his left hand prior to this, Shigaraki can only use this highly devastating move with his right hand, meaning keeping it occupied or incapacitated limits his ability to obliterate all his enemies in a single move. This comes in handy during the Paranormal Liberation War Arc, when the backlash of his incomplete body being pushed beyond its limits nearly causes Shigaraki's entire right arm to fall off, being attached to his body only by strips of skin and muscle. The precious few seconds Shigarakai has to spend positioning his barely-attached limb with his mangled left hand to unleash the Decay Wave gives Midoriya enough time to combine Blackwhip and Float to yank him skyward to continue the fight mid-air.
    • As of Chapter 341, he appears to be making serious efforts into overcoming this disadvantage, apparently overclocking his new Healing Factor to the point of Body Horror in an effort to regrow his missing fingers and thus utilise his full power with both hands in time for his final battle with Izuku, succeeding in re-growing the nubs of his fingers after torturous physical trauma. When he finally regains control of himself after an extensive physical beatdown whilst his master was in control of their body, he does via 'shedding' his upper half like a raincoat, which leaves him with some raw-looking musculature and his left hand fully reformed.
  • Actually Pretty Funny: In chapter 366 he lets out a snort of laughter when Mirio shows off his "Full Moon Risin' Tonight" move which actualy distracts him long enough for Izuku to come back into the fight and land a surprise attack. We know it's Tomura specifically who laughs because the All For One vestige can only utter a startled "Huh?" at the same time as he snorts.
  • Adaptation Dye-Job: A downplayed example. In the color pages of the manga, Shigaraki is shown with grey hair, whereas his anime appearance gives it a blueish-grey tint. After his power fully unlocks in his fight with Re-Destro, the anime turns his hair white as a sign of his power level rising.
  • Ambiguously Human: After he undergoes Dr. Garaki's horrific All For One transplant procedures, his body becomes greatly enhanced beyond what should be humanly possible. He also becomes able to morph his body into new shapes in response to the number of Quirks he has inside him, citing it as the next step in evolution. But Shigaraki's transformations all lean into Body Horror and look rather grotesque, calling into question whether or not he can actually still be considered human.
    Yoichi: Freed from the shackles of humanity, his power now swells. A transcendent one is coming...
  • Ambiguous Situation: Though unstated, it is greatly hinted that All For One might have sneakily bestowed the Decay Quirk upon him, indirectly enabling his childhood trauma as a means of isolating and manipulating him for his plans and as a means of mocking Nana and All Might's efforts as heroes in opposition to him.
    • Kotaro notes that Tenko has not shown signs of having a Quirk even at five years old, and Izuku later discovers that those who naturally possess a Quirk cannot gain a second Quirk without severe side-effects — in the case of the holders of One For All, they suffered from Rapid Aging from the extensive power they received burning away at their life force, with only the Quirkless All Might and Izuku immune to this. Despite this, and his goal being to become an immortal Demon Lord, All For One has no hesitation in giving Tomura his original Quirk with all its stockpiled Combo Platter Powers as a part of his plans, implying that he fully believes Tomura will be unaffected from any negative consequences of possessing more powers than he was 'naturally' gifted with.
    • Tomura's Quirk itself bears no resemblance to anything seen in his family lineage. Eri's example shows that it is possible for mutant Quirks to unexpectedly manifest in children, but in her case everything learned about it and its effects was done by guesswork and experimentation, and even by the present time the heroes aren't fully certain if her Rewind is the primary effect of her Quirk or a beneficial side-effect. However, All For One and Garaki seem quite confident when explaining the reasoning behind Tomura's Quirk, and even certain that it is linked to Tenko's hatred, encouraging him to embrace it as a source of strength to better control his power, implying that they're far more familiar with the 'new' Quirk than the boy whom it manifested in.
    • Despite the extensive damage Tomura's Quirk caused to the surroundings when he decayed his family home, and the death of an entire family overnight, no police or heroes responded to the crisis, and no records were made afterwards, leaving All Might and Gran Torino in the dark as to what became of Nana's family even after they were told about Tomura's familial connection to her, and nobody seems to have alerted the authorities when Tenko was staggering around the street covered in blood. Despite this, All For One was able to appear before him when he felt most abandoned, and recovered the bodies from the rubble afterwards to fashion their remains into Tomura's Companion Cube as a means of stoking his hatred. All For One even knew who Tenko was when he found him. Garaki later reveals that All For One made a point of locating 'twisted, warped seeds' that could serve his purposes, and appeared before them as a saviour in their time of crisis to gain their trust, as shown by All For One being aware of Touya Todoroki's accidental self-immolation and able to spirit him away quicker than any crises responders to the scene, implying that Tenko's situation was more calculated than he realised at the time. Further, the man who brought Tenko home to his parents is identical to All For One's appearance when he rescued Toya. There is nothing definitive stated about this one way or the other, but it would fit the villain's willingness to go to extensive lengths just to inflict as much pain as possible on his enemies.
  • Animal Motif:
    • Unusually for an evil character; butterflies. When characters are discussing how much potential Shigaraki has for evil, it's often accompanied by images of him with butterfly wings to display his metamorphosis into a pure villain. Receiving the original All For One Quick even requires he go into incubation, complete with an image of a terrifying-looking Shigaraki rising from a cocoon with butterfly wings on his back to drive home the point. Once he sheds his master's control over their body and regain his 'Tomura' personality, he does via literally "shedding" his upper half like it was an insect carapace. He does it once more in gorier fashion from within the vestige world, blowing up All For One's vestige from the inside.
    • Even more unusually, lemurs according to the volume 30 character page. More specifically aye-ayes, noted for their elongated digits, which keeps with the hand symbolism frequently attributed to the character.
  • Antagonist Abilities: Shigaraki's Decay makes him inherently difficult to fight, for several reasons. Against Close Range Combatants, he has a decisive advantage, as his ability can begin disintegrating the target's body starting from a point of contact. The target then has to amputate the part that's rotting or their entire body will decay. While fighting the Meta Liberation Army, the range and scale of his power increase dramatically, becoming capable of demolishing an entire city block. And after undergoing an intense medical procedure, he also gains the original All For One Quirk.
  • Antagonistic Offspring: A grandchild example. He hates his grandmother and blames her for everything that has happened to him.
  • The Antichrist: Designated as such to contrast with Midoriya's status as The Chosen One, with plenty of biblical allusions to boot. His sheer hatred for humanity combined with his immense power and All For One grooming him to be the greatest villain of all time turn him into the single greatest threat the world has ever seen. Granted, All For One wants to share in the glory by merging their two individual personalities into one, but by all means he's succeeded in creating a Symbol of Fear to destroy everything that All Might, the Symbol of Peace, had built up over his career.
  • Arch-Enemy: Both he and Midoriya are destined to lead the battle between good and evil as the next number one villain and hero respectively. The both of them even inherit their mentors' Quirks. The relationship gains further significance when Midoriya senses Shigaraki still has a part of his old personality as Tenko somewhere inside him, crying out for help once All For One steals his body so he can obtain One For All at last by using his endless rage. Midoriya then expresses his wish to save Tenko while acknowledging he may not be able to manage it, and that there's likely no other way to save the world without murdering Shigaraki. However, even though "Tenko" wants to be saved, "Shigaraki" establishes they still share the goal of destroying everything to exact revenge for being abandoned even if somebody tries to help him, and proclaims he is Midoriya's foremost nemesis when he regains control of his body from All For One.
    Shigaraki: After all, I am your villain.
  • Assimilation Backfire: A few times, Tomura's attempts to gain the overwhelming power he needs to destroy society as quickly as possible have backfired upon him, leaving him worse off overall.
    • He undergoes an intense and torturous biological remodelling under Garaki's hands in order to become strong enough to receive the original All For One Quirk and be capable of using its accumulated Quirks immediately without having to gradually acclimatise to them or risking his body suffering blowback from the strain. However, it turns out the real reason for this was so that the Vestige of All For One that came with the Quirk could start hijacking Tomura's consciousness and undergoing a Split-Personality Merge between them, resulting in Tomura starting to gradually lose his individuality against the mentor he thought he'd replace as the next Big Bad — which is exactly what is happening, but not in the way he was lead to believe.
    • He manages to steal New Order... but Star and Stripe gives it one final command: New Order rebels against other Quirks. This effectively results in New Order rampaging through the vestige world, destroying some of his stockpiled Quirks and threatening to rip Shigaraki apart from the inside out. What's worse is All For One (the Quirk) can't destroy Quirks, meaning the only way to prevent it would be to transfer it to someone else.
    • One that actually works in his favour. The merging process between his psyche and All For One's vestige is based around Tomura's intense hatred, arguably the one emotion the sociopathic All For One can completely understand, and thus the driving force of Tomura's incredible willpower that enabled him to keep going through so much adversity against the MLA and the assembled heroes during the Paranormal Liberation War inexorably pushes their assimilation towards completion, with the more Tomura resists simply strengthening the process. However, the fact that All For One could only understand the negative aspects of Tomura's psyche to merge into his own means that the positive side of him, the parts that remembers the better times of his childhood and his friendships with others, are able to retain their individuality. Yet it's not as simple as Tomura's "good" side being separated from his "bad", as both Tomura and Tenko share the same wish to gain revenge on the world of heroes. It's another way to show that villains are also humans and not necessarily all good or all bad, something All For One can't conceive of since he sees everything like it's a cheesy comic book.
  • Asskicking Equals Authority:
    • During his fight with Re-Destro, Shigaraki unleashes his power to such an extent that he turns half of Deika City into a crater in an instant. After witnessing this show of force, and seeing his rival's expression of true freedom, Re-Destro surrenders and offers Shigaraki the leadership of the Meta Liberation Army, which consists of over 100,000 soldiers, vast wealth, high-tech equipment, and assets of various tier 1 companies. Shigaraki accepts the offer and becomes the Grand Commander of the newly formed Paranormal Liberation Front.
    • He later on accepts Garaki's extensive biological remodelling process solely on the grounds that despite his prior impressive showing, it still wasn't enough to utterly destroy everything that opposed him with no way for his enemies to resist, pointing out that his Decay started to affect his own arm after a short period of pushing his Quirk that hard and that Re-Destro was able to save himself by cutting off his own feet to stop the spread. As he desires to become powerful enough to overturn any tactics the heroes use and tear down society almost single-handedly if he needs to, Tomura essentially forcibly upgrades himself through Garaki's research to become powerful enough to obtain and use the original All For One Quirk and its extensive stockpile of abilities immediately, his awakening during the Paranormal Liberation War single-handedly turning the tide against the heroes. Even with Erasure being used on him, Tomura's base enhancements put him on a physical level comparable to All Might, and he either heals or powers through everything the heroes throw at him in an effort to slow him down. He only starts to falter when his new strength proves too much for his body after he was prematurely awakened, and even then he keeps fighting back and crushing the heroes even with his body starting to fall apart into bloody pieces. The only thing that comes close to stalling him for a meaningful length of time is Izuku unleashing One For All at 100% again, and even then, it's noted that Izuku will be permanently crippled before Tomura goes down for the count. Spinner and the other's sole 'victory condition' behind winning the fighting is rallying under Toura's banner and steamrolling the heroes in support of his immense power.
    • In the aftermath, despite the losses the Liberation Front suffered and only a handful of their numbers mangling to evade capture, Tomura's sheer strength is such that events become a Race Against the Clock for the heroes to track him down and stop him before he fully recovers from his injuries during the war and completes his 'incubation', gaining full control of his new powers and strengthened body without fear of his own power backfiring on him again. His battle with and eventual defeat of the American Number One hero, an outright Reality Warper, cements Tomura as the World's Strongest Man, capable of utterly devastating the remaining heroes alone if not for One For All's power, and even then, his 'evolution' puts him at being stronger than Izuku, even after the latter starts unlocking and combining his Combo Platter Powers together into an effective fighting style that outstrips any other hero. By the time the Final Battle comes around, Tomura required an entire tailor-made battleground to be combated with anything like a chance of victory, and even with his powers again sealed, his new ability to mutate his body to suit his immense powers puts the heroes in a losing fight without Izuku's sheer power to counter Tomura.
  • At Least I Admit It: What he feels separates him from other villains like Stain, Overhaul, and Re-Destro. While those three and other villains like them try to justify or excuse their actions and take a moral high ground towards Shigaraki, Shigaraki himself doesn't hold any pretense. He's just a guy trying to get rid of people and things he doesn't like. And he sees nothing wrong with that.
  • Author Appeal: Averted in regards to Shigaraki. Kohei Horikoshi likes drawing hands, as he finds them to be the most expressive part of the body, but he absolutely loathes drawing the "expressionless hands" that adorn Shigaraki's body. He even refers to Shigaraki as his nemesis in the Volume 23 omakes.
  • Awesomeness by Analysis: During the League's first fight against Aizawa, Shigaraki stays in the background and watches the fight from afar. Once he actually begins fighting the hero, he can perfectly predict when his Quirk will stop working, and disables the veteran teacher with ease.
  • Ax-Crazy: From a young age Tomura had a very unstable lust for destruction and killing due to All For One's influence. This allows him to commit as many atrocities as he wants until he achieves his goal of the absolute devastation of everything he hates (which so happens to be nearly everything). Even as his character development takes place he only seems reign his unstable rage though he still retains his desire for violence, but uses colder and more ruthless methods of execution.
  • Bad Boss: Early in the story, he is very callous with his subordinates, even threatening the unfailingly loyal Kurogiri for letting Iida get away. His Character Development has moved him well away from this, however, and by the time he assumes leadership of the League of Villains, he seems to have become a full-fledged Benevolent Boss. This contrast becomes especially prominent when All For One starts mentally hijacking him, as he pointedly flees the battlefield and abandons several members of the League, including the insanely-loyal Gigantomachia, to be captured by the heroes once Tomura is too injured and exhausted to resist his control anymore, framing this as Tomura's punishment for 'losing' the fight with the heroes. Spinner even pointedly notes that there's someone completely different from the Tomura he'd come to know in control, despite being unaware of the mechanics behind All For One's possession, simply from how differently the two treated their subordinates.
  • Bad Powers, Bad People: Disintegration by touch? Definitely a villain.
  • Badass Boast: Delivers a brutal one to the team fighting him at U.A., having deduced that Midoriya was supposed to be there with them before he got side-tracked and says whoever came up with the idea to defeat him in close quarters had to be an absolute moron to think it'd ever work given all his strength.
  • Badass in a Nice Suit: Shigaraki's outfit as the leader of the Paranormal Liberation Front incorporates a black suit and tie, similar to the type that Re-Destro wears, which was likely intentional to demonstrate his dominion over the former MLA's resources. He also puts one on before his battle with Star and Stripe, presumably because All For One was in control of him, but the suit becomes immediately destroyed anyway thanks to the battle that takes place. By the time of the Final Battle, he does away with wearing any upper-body clothing besides the tattered remnants of his Badass Cape, both due to the fact it would likely get shredded during the fighting anyway, as well as his new ability to sprout fleshy masses from his arms tearing apart any clothing he was wearing besides the cape draped around his neck.
  • Barbarian Long Hair: To contrast with his master All For One's tidy, dignified, Bald of Evil appearance and penchant for expensive clothing, Shigaraki is normally portrayed as something of an unkempt wild child with a thirst for violence. The longer his hair grows, the more he's shown able to properly indulge in hate-filled rampages against his enemies. In fact, his hair is literally shown to be visibly growing as a side-effect of his 'evolution' into the 'next stage of humanity' because of Garaki's enhancements to enable him to contain All For One's accumulated might, a process he compares to the 'growth' of nails and hair being a natural bodily process he can not access and control as a weapon. His appearance in the Final Battle is the exact opposite of his master's, with free-flowing hair and dressed in tattered rags, showing how he cares more for results than his own appearance.
  • Bastard Understudy: Shigaraki was perfectly okay with staying the Dragon Ascendant, but All For One is such an egomaniacal narcissist with a Complexity Addiction he tries to enact a Split-Personality Merge between their two psyches instead. Yet Shigaraki had since grown into a superior schemer to his master, so this fails and Shigaraki obliterates his vestige so he can maintain the title of the world's strongest, deadliest villain.
  • Battle in the Center of the Mind: The only real glimpses at Shigaraki himself we get after All For One successfully pulls a Grand Theft Me on him are entirely metaphysical, with him resisting All For One's attempt at a Split-Personality Merge during Final Act. This culminates in All For One well and truly absorbing him, but neglecting to account for his positive/neutral traits as Tenko, splitting that part of him off and allowing him to put up more and more of a fight as their shared body sustains damage. And in the end, he "molts" and sheds All For One off like an old skin, ultimately winning.
  • Be Careful What You Wish For: Shigaraki desired All For One's power and after months of painful surgery, he received it... along with the vestige of All For One, who can forcibly take control of his body.
  • Benevolent Boss: After assuming leadership of the League of Villains. This is highlighted by his utter rage at Magne's death and Overhaul destroying Mr. Compress' arm. This is shown again in Chapter 148, where he has an almost beatific appearance while expressing his faith in Toga and Twice. Spinner is even able to tell when All For One is controlling him because Tomura liked to do things like play league of Legends with Spinner, and the sociopathic megalomaniac cares nothing for his 'pawns'.
  • Berserk Button:
    • He loses his cool when someone hits his father's hand. He drops this as he matures as a villain.
    • Stain. When Dabi mentions that the only reason he joined the League is to carry on Stain's will, Shigaraki almost murders him and Toga on the spot.
    • Adding onto the above, stepping on his authority as the aspiring big dog among villains makes him really angry. Stain was only the first of them, he grows similarly annoyed at the Shie Hassaikai trying to muscle in on their territory. Like the hand thing, he gradually grows out of this to the point that when the Meta Liberation Army decide to pick a fight with him he keeps his cool. It's eventually dropped entirely, but less because of character growth and more because Shigaraki manages to claw his way to the top of the pecking order.
    • A long-standing one he's carried from his childhood is simply being 'denied' or having his wish to freely destroy everything around him out of his overwhelming hatred rejected. This stems from his father repeatedly preventing him indulging in his childhood dream to be a hero, in escalating measures to prevent the young Tenko turning out like his Grandmother's example, and his family passively going along with it, leaving Tenko feeling alone and abandoned by those who should have been 'on his side', fuelling his anger at his unfair treatment. This translates into Tomura becoming more ferocious and dangerous whenever the heroes actually start inconveniencing him or starting to gain the advantage over him, viewing it as everybody ganging up on him again and fueling his primal anger in response, to the point of feral intensity the more determined he becomes to win.
    • After he successfully lands a fatal attack that blows a hole in Bakugou's heart, he becomes quietly irritated, then steadily more and more angry as the heroes proceed to ignore attacking him and prioritising reviving Bakugou from the brink of death, screaming at them that he's 'already destroyed that one', so they should cease trying to undo what he breaks. His scrambled inner thoughts make it clear that he's really angered by how they're devoting so much effort on saving a child in need when nobody bothered to give him the same treatment when he was in less lethal circumstances as Bakugou, feeling this 'favouritism' unfair. His inner childhood self of Tenko even morphs into his blood-soaked, traumatised appearance in response to his emotional state to drive it home.
  • The Berserker: An inherent part of his nature All For One actively seeks to nurture, though he's usually fairly more level-headed and rational in battle than most examples, able to deduce weaknesses in his opponent's abilities to target and avoiding acting rashly during the early half of the story. He only really starts to become this after gaining the power to directly confront opponents numbering in the hundreds solo, and being forced to rely on his base physical enhancements after Erasure is used on him. The more beaten down Tomura becomes, the more determined he becomes to win, even mangling his body to shreds and shrugging off injuries that would easily kill anybody else in his mad intensity to seize victory. It's later revealed that All For One's entire plan hinges on making Shigaraki such a spiteful and hateful young man so he can be angry enough to forcibly steal One For All.
  • Biblical Motifs: Ohhhhh boy. The All For One vestige first offers him the power of the Quirk with his arms outstretched as if he were on a crucifix. Later, the tangle of personalities that consist of All For One, Shigaraki, and Tenko Shimura formed from the union can be perceived as analogous to the Holy Trinity from Christian doctrines. All For One as the father, Shigaraki as the son, and Tenko as the holy spirit. Combined with Shigaraki being described as a "transcendant one" by Yoichi upon his awakening and referred to by similar terms throughout the story, Shigaraki becomes a Dark Messiah in his own right. His and Izuku's final conflict even starts in earnest once his Tomura personality 'rises from the dead' after All For One tried to 'kill' him.
  • Big Bad: He becomes the sole big bad after All For One's defeat and has been the main threat throughout the rest of the arcs. Things grow hazy by the Paranormal Liberation War Arc, where he gains his master's Quirk and All For One himself takes over Shigaraki's body and retakes the position as the big bad of the series. And while All For One's true goal is to merge their consciousnesses together as one, essentially rebirthing himself with Shigaraki as his other half, he still fully intends to be the dominant persona. Unfortunately for him, Shigaraki's will to destroy is so strong that he's unable to keep him under control and Shigaraki supplants his vestige, establishing himself as the story's true Big Bad to underscore All For One's petty attempts at trying to steal his thunder.
  • Big Bad Duumvirate: With his master All For One. Shigaraki leads the League of Villains publicly, while his master, All For One, monitors him from the shadows. Their dynamic changes as the story advances.
  • Big Bad Ensemble: During the Paranormal Liberation War Arc, Shigaraki and his master All For One fight over control of their shared body after Shigaraki gained All For One's Quirk, each one taking control at some point. In Chapter 295, however, All For One takes full control of Shigaraki's body and Midoriya sees Shigaraki as someone to rescue despite being archenemies. When 'Tomura' regains control of the fighting after Izuku utterly thrashes All For One however, he makes it clear that despite Izuku's efforts, he's still determined to oppose and kill him regardless, as 'I (Tomura) am your villain'
  • Big Bad Wannabe: This trope goes from Played Straight to averted. He does step up to the plate as the Big Bad after his master is defeated and jailed, but All For One set him up to eventually inherit his power, all so he could use him as a vessel in which to free himself and continue his plan of being the ultimate evil. The vestiges of One For All later comment on this, seeing him as a mere stepping stool for All For One's goal of becoming more powerful. Despite this, Shigaraki being played is shown to be more due to inexperience rather than outright inferiority. Endeavor, Hawks, and Best Jeanist also discuss why All For One even needed to manipulate Shigaraki like this, coming to the conclusion that he doesn't have the emotions necessary to steal One For All, meaning both Quirks have evolved beyond him. This finally comes to fruition once Shigaraki tears All For One's vestige to shreds and gains true ownership of the Quirk, making All For One the real Big Bad Wannabe in the long run.
  • Bloodbath Villain Origin: He Used to Be a Sweet Kid, but his childhood came to an abrupt end when his Quirk activates for the first time following a beating from Kotaro. He freaks out at this, accidentally killing most of his family in the process before deliberately murdering his father. His newly-awakened Decay at that point only disassembled the targets into large meaty chunks rather than the fine dust they become by the present, resulting in the young Tenko getting absolutely drenched in their viscera during this process. All For One finds him soon after this and decides to groom him as a successor, triggering his Start of Darkness in earnest.
  • Blow You Away: One of his favorite Quirks inherited from All For One seems to be Air Cannon, as he uses it extensively against the heroes. Quite cleverly, he also combines Air Cannon with a Radio Waves Quirk to send out a blast that doubles as an EMP.
  • Body Horror:
    • After using his Quirk at its full potential to level a good chunk of a city, his arm is left ragged by the backlash. In the Paranormal Liberation War Arc, due to him prematurely awakening from his medical procedure and pushing his body past its limits, his body starts to break down, leaving him with a huge gash across his chest. Also, when Endeavor blasts him with a point-blank Prominence Burn, Shigaraki's body is badly burned. And when Midoriya leaves a huge crack in his skull, All For One's grinning face can be seen.
      • Putting it bluntly, ever since he gained Hyper Regeneration, Tomura's body has been mangled and devastated by multiple different Quirks and sheer physical trauma, to the point that it's half-implied that the only reason he doesn't die even with his super-healing is his sheer willpower to persist until he's destroyed everything, allowing the Quirk to pull him back together no matter how badly he's hurt. It's to the point that the heroes are horrified at the fact that he just won't die. After Star hits him with the Tiamat intercontinental cruise missiles, Tomura's body is basically a charred skeleton with stripes of flesh left on it, and he still immediately bounces back to continue the fight with a massive Slasher Smile on his face— what's left of it.
    • His body has become prone to cancerously grow into a disgusting blob of hands and flesh for brief moments of time before he pulls himself back together. All For One clarifies this is because he's slowly overcoming the Quirk Singularity, which happens when a body is overloaded with too much power from one or more Quirks. In Tomura's case, he has a body as strong as All Might's at max power to handle All For One and its multiple Quirks, but has to wait for it to be completed thanks to all the physical punishment he's suffered at the hands of the heroes. More horrifying still, he's capable of using this as a means of attack even with Erasure being used on him, implying that this ability doesn't count as a Quirk, and that Tomura has become something other than human as a result of his incomplete treatment and the sheer damage he's endured.
    • As a result of his anger over the heroes trying to revive Bakugou and how it reminds him of how nobody attempted to save Tenko Shimura as a young child in need makes him manifest fleshy growths in the shape of his family and the old lady who refused to aid him from his body — in essence, manifesting the figures he considers intrinsically linked to his childhood trauma through his transformative growth. They become part of a new defensive form he takes on, comrpised of hands closing around his torso and face to shield him from harm, with their heads at the tips of a giant hand where his left arm used to be.
  • Body Motifs: Hands. His Quirk involves destroying things provided that all five digits on his hands are touching them, and he has disembodied hands all over his body, including his face. This is deliberate as Horikoshi enjoys the expressiveness of hands, his own Author Avatar is a hand mutant, and takes it to its logical extreme with Shigaraki's design.
  • Brilliant, but Lazy: A reoccurring motif of Shigaraki's character development is that while he possesses the raw power and intelligence to succeed All For One, he often has to be pushed by outside forces into honing his skills, usually in the form of a rival faction.
  • The Bus Came Back: It's a bizarre thing to explain. While Shigaraki technically never goes anywhere, All For One becomes the dominant personality in their Fusion Dance and more or less keeps him on a tight leash and buries his persona deep within his subconscious to maintain his Grand Theft Me gambit. However, just as All For One grows stronger by feeding on his hate, Shigaraki's original aspect as "Tenko" emerges and begins fighting back against his abusive adoptive father just like he did to Kotaro, albeit in conjunction with the heroes dealing relentless punishment on their shared body to split the two of them. It results in him literally shedding his old merged personality as an old skin and becoming "reborn", returning to proclaim he is Midoriya's true Arch-Enemy.
  • Bystander Syndrome: Became a victim of this after he destroyed both his family and his house. He wandered the streets hoping for someone to help him, but no one wanted to because of how frightening he looked and assumed a hero would do it for them. This is a major part of the reason why he hates the society the world of heroes created, to the point of basically becoming his main motivation, as he persistently strives to becomes powerful enough to destroy everything, hero and civilian, connected to it, considering it a deserving fate for a society that denies and rejects his entire existence as a victim and a villain. His trauma concerning this is so intrinsically linked to his desire to destroy, when his Body Horror powers start growing facsimiles of his family into a massive hand-shaped amalgamation, the old lady who abandoned him is counted amongst his family as people he feels hurt and ignored him.
  • Character Development: When initially introduced, Shigaraki was a psychotic brat who frequently had temper tantrums, and had to be held back from doing anything stupid by Kurogiri. However, once having realized his own convictions, he becomes a lot more cunning, manipulative, and patient. This can be seen in his ability to work with "Stain fanboys" in the expanded League, and keeping his temper under control after Bakugo damages his father's hand. Losing his mentor, and later the death of Magne drive his development further (exactly as planned in the former case) as he grows to value his team more. By the time he meets Gigantomachia and Dr. Garaki, he doesn't even lose his cool, and tries to talk to them rationally. His relationship with his team has also deepened to the point where he remains level-headed towards Spinner for questioning the League's lack of direction. By Chapter 237, he states he just wants the League to live as they see fit. It's later revealed that his development, and the fact that he was capable of doing so in the first place, was the entire reason behind All For One grooming him to become his 'Next Me', worthy of inheriting his Quirk. He requires a strong emotional willpower to overcome the combined wills of the vestiges stored within One For All and absorb it for good, something he is fundamentally incapable of doing himself, and to that end he orchestrated much of Tomura's experiences to encourage his hatred as a source of strength for him, which becomes the focal point upon which the vestige of All For One himself can start assimilating itself into Tomura's psyche, essentially hijacking Tomura's development as a weapon against One For All.
  • Characterization Marches On: He used a lot of video game lingo and metaphors during his debut, almost treating the USJ attack as if it was a video game level. From his next appearance onward, he no longer talks like that, implied to be because that was his first actual appearance as a villain before experienced heroes, and his defeat and experiencing the kind of adversity he was up against somewhat humbled him and forced him to treat his subsequent efforts with more seriousness.
  • Character Tics:
    • In a similar fashion to Uraraka, touching objects he doesn't want to decompose by using only a few fingers at a time.
    • His habit of scratching himself is a tic that he has had since childhood which started as an "itch" before his Quirk fully activated. According to All For One, his "itch" is a byproduct of his need to destroy physically manifesting itself and can only be alleviated by killing something with some proof of that being the fact he stopped itching after killing his family. As he got older, he settles for scratching his neck which gets increasingly violent when he's in the middle of a breakdown. Thanks to character development, he gets better though he still scratches himself on occasion.
  • Charles Atlas Superpower: He was able to move faster than eye can see during the USJ Arc. Chapter 276 reveals that the procedure that transferred the All For One Quirk to him also modified his body to grant him immense strength even without a Quirk, allowing him to leap high into the air and move with intense speed. He frequently compares his base physical abilities to be comparable to All Might himself in his prime during the Final Battle, illustrating how hopeless it is to fight him even when he can't use his stockpiled Quirks.
  • The Chessmaster: He was a Psychopathic Manchild, but his character development is slowly turning him into this. This is best seen at the aftermath of the Internship Arc; after spending the arc basically subservient to Overhaul and keeping his ego down, and letting Overhaul and his gang take on the heroes, he backstabs Overhaul at the exact right moment to make it hurt the most, specifically by capitalising on the latter's inability to see his subordinates as anything except disposable pawns, whereas Tomura is actually capable of believing in his own allies as equals and letting them decide when to best betray Overhaul. To add insult to injury, he cripples Overhaul to the point that the latter is basically Brought Down to Normal, and runs off with his prized possessions.
  • The Chosen One: A Dark example. His grandmother trained All Might and is thus indirectly responsible for the current peace in society, but his past heroic lineage is implied to be the main reason why All For One focused on raising him to be a villain as a massive 'screw you' to Nana and All Might, deriding their efforts and inability to protect those closest to them from evil. This serves as a further contrast to Izuku, who has no prior connection to the chain of succession about One For All, but was naturally suited to bring forth its full potential as the last holder.
  • Clipped-Wing Angel: His 'ideal' defensive form did manage to be effective against the heroes around him in a short burst, but the moment Deku shows up, it turns out to be completely ineffective. Not only is he slower due to his increased mass while Deku is faster, the main benefit of the form, a defensive armor, is completely worthless as Deku hits hard enough that it doesn't protect him at all. He winds up literally getting beaten out of the form without landing a single hit on Izuku and left with a massive gaping hole in his chest from the sheer damage.
  • Clothing Damage: Over the course of his battle with Re-Destro, Shigaraki's outfit gets progressively more torn and damaged, culminating in him being left wearing the remnants of his pants after he unleashes his ultimate attack. This happens again in the Paranormal Liberation War Arc where he starts off in a bodysuit similar to Nine from Heroes Rising, but as his battle with the heroes progresses, his suit becomes damaged until he's left shirtless. Ditto during his fight with Star and Stripe, though in that case, he was lucky his pants were left behind after she resorted to Nuke 'em against him. During the Final Battle, he does away with wearing any upper-body clothing altogether save his Badass Cape, especially since his new Body Horror abilities dramatically warps his flesh beyond the human template as befits his situation.
  • Coat Cape: Shigaraki's third outfit includes a coat with a fluffy collar, not unlike Overhaul's, that he wears in this fashion, due to his arm injuries sustained during the war making it impractical for her to pull the sleeves on. He remarks that it's actually pretty itchy to actually wear all the time.
  • Combat Tentacles:
    • In Chapter 285, All For One's lingering consciousness takes control of his body, causing him to manifest the Rivet Stab tentacles, which he uses to impale both Endeavor and Bakugo. Unlike All For One, Shigaraki can sprout the tendrils from his back as well, allowing him to move Doctor Octopus style.
    • When he's warped to the flying battleground specifically created to combat him and his Decay wave, he reveals that his body's 'evolution' as a result of adapting him to contain the immense power of All For One has granted him the ability to sprout massive tumourous growths of fingers by controlling his body's ability to 'grow', like hair and nails naturally do, using them in this fashion to fight the heroes. As a bonus, since the fleshy growths are all fingers, if not for the effect of Erasure being used on him at the time, he would be able to use Decay from every single one of them.
  • Combo Platter Powers: After gaining the original All For One Quirk, Shigaraki can combine different Quirks together to create devastating attacks. During his fight with Endeavor, he combines an Air Cannon Quirk with a Radio Waves Quirk, allowing him to blow the heroes away and disrupt their communications, and also awakening some of the High End Nomu for backup. His quick handling of the abilities in tandem was partially Invoked by All For One, who intentionally prepared as many simple-to-use, but powerful Quirks inside his original in preparation for passing it on to Tomura, but is also implied to be an early sign of the Vestige of his master starting to assimilate into his psyche the more he draws on his stockpiled abilities
  • Cosmic Plaything: Life hasn't been kind to Shigaraki, rampant psychopathy aside. He was born into a household where his father would physically and emotionally abuse him while his family stood by and watched, which invariably led to them all being ill-equipped for his Quirk to manifest, killing them all. He wandered the streets after and everybody he came across refused to help, until All For One of all people found him and took him in, where his psychological torment would only continue. All For One groomed him into the Misanthrope Supreme over the course of 15 years, awaiting the day he would transplant his consciousness inside him to use as a meat suit and employ his willpower in stealing the elusive One For All with the intent of burying whatever was left of Shigaraki deep within. It's no wonder he eventually turned into the most dangerous villain the world had ever seen.
  • Costume Evolution: Shigaraki has a few through the series whenever important milestones in his villain career happen:
    • When Shigaraki becomes the guiding force of the League of Villains, without the influence of All For One, he starts wearing a dark black Badass Longcoat, showing how he's come to embrace his authority and his evolution into a competent villain.
    • After taking over the leadership of the MLA and reforming it and the League into the Paranormal Liberation Front, Shigaraki decks himself out in a suit and spiffy coat to demonstrate his newfound strength and influence. He continues to wear his one surviving hand as a face mask replacing Father. However, unlike before, the hand no longer serves as a mental crutch and is now just there to fit with his former aesthetic.
    • During the Paranormal Liberation War, he's still in the process of Garaki's biological remodelling, and thus is decked out in a form-fitting medical bodysuit inside a People Jar, similar to Nine from Heroes Rising, as he 'incubates'. When he awakens, he feels cold from being exposed to air for the first time in months, so he kills the nearby X-Less and steals his cape as a partial blanket, but seems to take a liking to the look afterwards, incorporating it into his later appearances.
    • During his fight with Star and Stripe, as a result of the Split-Personality Merge with All For One's vestige going increasingly in his master's favour, Tomura's body wears a shirt and suit reminiscent of All For One's preferred look, in addition to his cape, though both are quickly destroyed during the battle thanks to a direct hit with a WMD.
    • For the Final Battle, Tomura shows up completely shirtless, save for his cape, though in this case it turns out to be partial pragmatism, as his new ability to explosively grow his flesh beyond the human template would destroy any clothing he wore anyway.
  • Crazy-Prepared: In Chapter 276, it's revealed that Shigaraki used his newfound control over his Decay Quirk to avoid hitting the capsules for the sleeping High-End Nomu so he could summon them to aid him later.
  • Creepy Monotone: Shigaraki's voice is very eerie and quavering, and in the manga, his speech bubbles are drawn as jittery with messy text, used to illustrate that he's unstable and could come unhinged at any moment. They smooth out at the climax of the fight with the Meta Liberal Army and Tomura coming to terms with his past, indicating his speech taking on a more serene tone to befit his self-enlightenment.
  • Creepy Souvenir: That hand Shigaraki wears on his face? It's heavily implied to be and later outright confirmed to be his father's actual hand and all that was left after using Decay on him. The hands Shigaraki wears around his neck, upper arms, elbows, and wrists are later revealed to belong to his other family members, killed the same way after his Quirk's accidental activation. The ones on his neck are his mother's, the ones on his upper arms are his maternal grandfather's, the ones on his forearms are his maternal grandmother's, and the one's on his wrists are his older sister's. The last five hands (on his shoulders, sides, and the back of his head) are perhaps the most disturbing of all: four of them belonged to two random punks who made the mistake of crossing a young Shigaraki. The last one? It's from his paternal grandmother Nana Shimura, who was murdered by All for One, given to Shigaraki to replace one of his father's hands.
  • Curb-Stomp Battle:
    • Once he regains his memories of his childhood, his battle against Re-Destro is a total wash. He dispatches of the villain's attacks easily and the resulting Decay wave leaves the man crippled without legs. This single power-up is what allows him to turn the tide against the entire Meta Liberation Army without even needing to use Gigantomachia's immense strength, and Re-Destro swiftly hands over the reins to him so they can then form the Paranormal Liberation Front together.
    • Delivers one once again, this time to the heroes during the final arc when they try to contain him at U.A. to defeat him once and for all. With Izuku pulled off by Himiko to a different location by accident, he's free to stomp what are essentially level 50 enemies compared to his high stats being level 98 or 99, with him being at near full compatibility with the original All For One Quirk. For example, Bakugo's strongest attacks leave a noticeable burn but otherwise barely faze him, and other powerful attacks fail to even break his skin, and he coldly continues to lay the beatdown on the group as they try to hold on just long enough for Izuku to arrive and stop him. Subverted, however, as he learns too late their attacks were piling up due to his Healing Factor being disabled and is forced to change to a purely defensive form because he was actually in danger of losing if he didn't.
  • Dark Is Evil: His preferred attire color is black, which serves to emphasize his malice. After the Paranormal Liberation War, Nana's hand, the sole remaining Creepy Souvenir from his family, is scorched black by Endeavor's flames when he's trying to overtax Tomura's Healing Factor, and placing it on his face awakens Toura's instinctual Unstoppable Rage when the villains are backed into a corner... and facilitates All for One starting to possess him as the stronger Tomura's anger, the more All For One's grip on his mind and body grows, fulfilling the trope even more.
  • Deadpan Snarker: While not as pronounced as someone like Dabi, by the time of the Internship Arc, he has developed into one of these. In the Paranormal Liberation War Arc, at one point he dryly wonders if he is using the correct hand to reenact All Might's iconic pose at Kamino... while standing atop a downed Endeavor's chest. This starts to become slightly more spiteful and mocking as time goes on and his mental assimilation with All For One gets stronger, belittling the heroes' efforts and dryly noting their futility against him with his current state.
  • Death of a Thousand Cuts: During the Final War Arc, his Healing Factor is negated. He doesn't think much of it due to his Super Toughness...which backfires, as while individually their attacks aren't doing very much, the sheer number of attacks he takes did start piling up. This begins to effect him, and his body has to enter a purely defensive form with the narration flat out stating the heroes beat him in round one.
  • Despotism Justifies the Means: Shigaraki's merger with All For One's vestige begins to alter All For One's endgoal more towards this, wanting to rule a world where everyone is oppressed and exploited by him, but in the process are all equal.
  • Destroy the Abusive Home: After killing his entire family, Shigaraki's Decay Quirk completely destroyed the house his father built.
  • Determinator:
    • Easily rivals Midoriya in this category, if not surpasses him, as per All For One's ultimate plan. This is best demonstrated in Chapter 223, where Gigantomachia has been hunting and continuously fighting him for 48 hours straight with only three hours for Shigaraki to rest. And this has been going on for a month and a half.
    • After the machines meant to revive him from his power-up coma were destroyed by Mirko, he was able to bring himself back from clinical death with nothing but his own sheer determination.
    • After he obtains the original All For One Quirk, his own willpower and determination proves to be a more vital asset to him in battle with the heroes than any of his innumerable new abilities. Tomura gets put through horrific damage that would easily kill anybody else, faces numerous handicaps in battle that limit the power he can bring to bear, faces an outright Reality Warper in battle and get hit with a WMD head-on, and not only never gives up his desire to win, but keeps finding ways to fight back against the heroes, at times even seeming to hold his mangled mess of a body together through sheer willpower and refusal to lose, overpowering them with his sheer might and enduring everything they throw at him to come out victorious in the end. His unstoppable willpower is exactly what All For One was aiming to cultivate in him through his tutelage under his master, along with guiding Tomura to use his overpowering hate for everything as a source of strength, to create a consciousness that would be powerful enough to overcome One For All in a battle of willpower and finally absorb the Quirk for good, once All For One absorbed said psyche into himself first.
  • Discard and Draw: During the Final War Arc, the heroes actually manage to beat his 'mass of fingers' form, forcing his body to abandon it in exchange for a primarily defensive form.
  • Disease Bleach: Shigaraki didn't always have grey hair and red eyes. When he was five years old, he shared his family's dark hair and eyes. He only got those features after killing his family. Re-living the traumatic memories of their deaths when his family's hands are destroyed and his ensuring mental breakdown causes the hair colour to turn fully white and wispy, which in the manga helps make him look more ethereal and otherworldly after his revelation about himself and his purpose in the world.
  • The Dog Bites Back: Shigaraki's first intentional victim was his own father as payback for the abuse he suffered growing up.
  • Dragon Ascendant: Following All For One's defeat, he becomes the full leader of the League of Villains, just as his mentor wanted. Following the Paranormal Liberation War Arc, he's more or less Demoted to Dragon. But then All For One's plan is shown to be merging their personalities together into a singular Big Bad God-Emperor, leaving All For One's original body behind so they can become a new being. However, All For One is ill-equipped to deal with the fact that Shigaraki is spurned into becoming a Bastard Understudy instead, forcibly prying the role of Big Bad away from his mentor and confronts Izuku in a climactic showdown that decides the fate of the entire world.
  • Dragon-in-Chief: To All For One. He eventually becomes the full leader of the League of Villains after All For One's defeat. Shigaraki also claims he doesn't want to be like his master, but better than him. Complicating matters is the fact that All For One fully agrees with him, and in fact considers his original, permanently-disfigured and broken body to be incapable of ever achieving Tomura's full potential, and is thus fully willing to 'sacrifice' himself for Tomura's sake. However, this doesn't mean he actually intends for anybody else to become the 'Demon Lord' in his place, and so he instead plans to become Tomura and achieve his ambitions through him.
  • Dragon with an Agenda: All For One's goals and his don't entirely intersect. All For One wants to rule the world while Shigaraki wants to obliterate it entirely. He makes it clear to his master that whatever his plans to use him to steal One For All, he is not having it and actively resists his attempts to merge their vestiges together. It can be argued All For One keeping him on such a tight leash is something of a reprieve for everybody, as outside of his control he'd annihilate everything and everyone he doesn't call a friend. Once All For One does lose control, Shigaraki swiftly proves himself the more pressing threat and embarks on his mission of destroying everything, with Izuku at the top of his list.
  • Dramatic Irony: Following the fight with the MLA in Deika City, Shigaraki loses his thumb, index, and middle fingers on his left hand to Re-Destro. This leaves him with exactly seven fingers— the same number that his grandmother Nana took in the OFA chain of succession, though he's completely unaware of this.
  • The Dreaded: Takes a while for him to get there, seeing as society viewed him as some incel upstart at first despite causing a fair amount of carnage. Once Izuku informs him he lacks any solid direction, Shigaraki slowly develops into a competent leader and grows more powerful, training Decay to the point it can destroy entire cities if he pushes himself hard enough. All it takes is a single glare from him to make people petrified. And as if that weren't enough, Garaki enhances his body to become strong like All Might even without any Quirks so he can handle the power of the original All For One Quirk, making him hands down the strongest character in the entire series except maybe Izuku operating at 100% with all his own extra powers active. In the aftermath of the Paranormal Liberation War, people openly speak about being terrified of his wrath and arguably fear him even more than All For One himself.
  • Early Installment Character-Design Difference: It's subtle, but he's actually changed art styles as his character has developed, from a highly detailed style that played up his creepiness to a less detailed style that still leaves him creepy, but also gives him a soft, almost beatific feel.
  • Emotional Powers: It is greatly implied that his Decay abilities are tied to his emotional state, specifically his hatred, seeking out and destroying whatever angers Tomura, with its omni-directional effect by the present day being because he hates everything around him all the time. His flashback to his Quirk awakening in chapter 235 has panels of a white-grey mass appearing in a dark background whenever Tenko is denied or rejected with his desire to be a hero by his family with it visibly growing larger and larger throughout the chapter has Tomura recalls all the times his individual family members let him down and 'abandoned' him when he needed support from Kotaro's abuse. This same mass is shown to reside inside Tenko's chest when All For One converses with him afterwards about his family's fate, implying it symbolises how his hatred has consumed his heart. Despite its uncontrollable nature when directly touching others, Tenko's newly-awakened decay's ability to 'spread' through the ground shows a targeted focus, in contrast to how Tomura uses it by the present, spreading outwards to decay his grandparents through the ground they were standing on and no further when he sees them, and going into overdrive when Kotaro appears, violently crumbling the house entirely to dust. Tomura's increased control over the Quirk comes with him achieving self-enlightenment over his nature and his desire to destroy society, in essence, focusing his hatred towards a goal rather than using it blindly, becoming able to control what decays around him rather than just destroying everything haphazardly.
  • Empty Eyes: Used to show when All For One is in control/fully merged with him. His pupils will revert back to at least some degree whenever his Tenko persona emerges, or his different personalities are vying for control of their shared body.
  • Even Bad Men Love Their Mamas: In Chapter 270, Shigaraki sees his long dead mother in his dream. It clearly shows that he still cares about her to some degree, enough that he turns back into a child in front of her. Unfortunately, it's not enough to stop him from embracing the path of villainy.
  • Even Evil Has Loved Ones: He still holds on to some lingering affections for his family, particularly his sister and mother. This is played straight with All For One; Shigaraki truly respects his foster father, stating it directly when he feels AFO's lingering presence inside his mind after receiving his Quirk, admitting he's truly grateful for everything he'd done for him. This is also played straight with the League Of Villains. Over time, he develops into a Benevolent Boss and grows to genuinely care for his comrades. He is horrified when Magne is killed by Overhaul and enraged when Mr. Compress loses his arm to the villain. He shows trust in Toga and Twice on numerous occasions and states that while he wants to destroy everything he dislikes, his allies are exempt from his goals. At one point, he even admits he has no need for a future of his own and just wants to see the League live how they want. It turns out this is the one thing that All For One didn't count on, as being told he never had friends causes a wedge to be driven between Tomura's personality and All For One.
  • Even Evil Has Standards:
    • During the Forest Training Camp Arc, he tells Kurogiri that he wouldn't send the new recruits into danger, claiming he wasn't that heartless.
    • He is openly appalled by Overhaul's lack of regard for his underlings, and killing Magne didn't exactly do his view on him any favors.
    • During the Meta Liberation Army Arc, he says that he won't forgive the army for toying with Twice since Twice is tearing himself apart to save the kidnapped Giren.
    • While Shigaraki has no qualms committing atrocities, he doesn't enjoy manipulating people, especially his comrades. He even denounces his own mentor for having such proclivities. This turns out to be a pivotal difference between them, as enough of Tomura's higher moral standards and good memories remain behind in his childhood self of 'Tenko Shimura', once All For One manages to completely assimilate the 'Tomura' aspect of his mind, that 'Tenko' can retain his individuality, as All For One can't understand all the good qualities he possesses. This means that part of Tomura is still capable of fighting back against his master's possession of him during the Final Battle, a realisation that notably unsettles the Smug Super 'TomurAFO' personality.
  • Evil Cannot Comprehend Good:
    • The reason why his plan to convert Bakugo to the League of Villains quite literally blows up in his face. He thought that Bakugo's violent tendencies meant that he'd be better suited as a villain, not realizing that Bakugo genuinely wants to be like All Might in spite of himself. Aizawa, All Might, and Bakugo himself pretty much spell this out for him.
    • Later on, this actually works in his favour, as as bad and crazed as he becomes by everything that's happened to him through his life and All For one deliberately encouraging his worst traits, he's still not as bad underneath as his almost inhumanly-sociopathic master, able to form genuine friendships and connections to others and fight for the sake of the League alongside his own wishes, something All For One is fundamentally incapable of. When his master's ultimate goal of enacting a Split-Personality Merge between himself and Tomura is underway, All For One can only understand and assimilate the negative parts of Tomura's psyche into himself, leaving the few remaining good aspects of Tomura behind in 'Tenko Shimura', which All For One didn't realise until 'Tenko' wrestled control over the body in outrage over Mirio claiming his misery was born from never having any friends growing up.
  • Evil Counterpart:
    • A pretty blatant one to Midoriya, as All For One's protégé compared to One For All's inheritor, especially given his Awesomeness by Analysis abilities. They both even receive their mentor's Quirks. They both wear red sneakers, even.
    • All For One deliberately engineered Shigaraki to become one for All Might, hoping to turn him into a "Symbol of Fear" to counteract the "Symbol of Peace."
  • Evil Feels Good: His narration during his flashback says that he felt the most pleasant of sensations once he murdered his father and that the incident stopped his constant itching. It's greatly implied that he feels happy and satisfied whenever he's in the process of destroying things that anger him —which by the present day is basically everything — regardless of the aftereffects on him personally. He has an ecstatic and delighted look on his face when he unleashes the full power of his Decay wave in Deika city, keeping it going even as the strain of pushing his Quirk so far starts decaying his right arm afterwards. His comments later imply he stopped decaying not because he wanted to, but because his body was on the verge of tearing itself apart satisfying his desire to destroy everything, and he undergoes Garaki's biological upgrades mainly so no physical limits will hold him back from indulging in his crazed happiness from annihilating everything again.
  • Evil Is Petty: In the Paranormal Liberation War Arc, the first thing he does after waking up from his medical procedure? Kill X-Less and take his cape as a blanket of sorts because he's cold.
  • Evil Sounds Raspy: Eric Vale gives Shigaraki a very coarse voice that doesn't break even when he is in the middle of a Villainous Breakdown. During his fight with Re Destro, after fully unlocking the power of his Decay Quirk and reconciling his past traumatic memories associated with it, accepting them as part of who he is, his voice loses its raspiness and becomes deeper, which is represented in the manga by his previously-shaky and unstable speech bubbles smoothing out and becoming clearer.
  • Eviler than Thou: Shigaraki wasn't kidding when he said he was running the show now: All For One's attempt at hijacking his body goes terribly awry and ends with his vestige being torn apart and cementing Shigaraki as the true Big Bad of My Hero Academia. Whether or not he'll extend the favor to All For One's physical self has yet to be seen, but All For One's Suicide Attack with Rewind almost guarantees he doesn't even need to.
  • Evolution Power-Up: With the amount of Quirks inside All For One, Shigaraki explains his body undergoes spontaneous growth to handle it. Erasure has no effect on this ability because it's a side effect of possessing so many Quirks, he's not using any to trigger it. He truly believes his body exploding into a sporadic tangle of hands is a step in evolution heroes will never be ready for, showing he will do anything to attain the power to destroy everything he hates.
  • Exact Words: He never explicitly told Toga and Twice to betray the Shie Hassaikai. But he didn't tell them not to. This allowed them to get past Nemoto's Quirk because there was technically no planned betrayal in the works, it was just something they chose to do later on, which Shigaraki was banking on, exploiting Overhaul's perception of subordinates as unthinking pawns to have his allies outwit him instead of himself.
  • Exotic Eye Designs: Upon "liberating" himself and coming to terms with his past, Shigaraki's eyes are drawn in solid circles progressively less frequently, but in an almost hatching type of style to reflect the new power he's unlocked with Decay. After acquiring the original All For One Quirk, his eyes oscillate between his own and having no pupils as All For One merges with him into a new being. Near the end of the process, Shigaraki's eyes have lost all solid lines and are done strictly in the hatching style to signify he and his master are becoming one and the same.
  • Expository Hairstyle Change: As the series goes on Shigaraki's hairstyle gets longer with each arc corresponding with his increased competence and threat level as a villain, giving a visual indicator that Shigaraki grows from being a fairly ineffectual, childish brat to a genuinely powerful and dangerous super villain. As his merging with All For One's vestige continues and his body starts adapting more to the enhancements Garaki made to his body to be able to handle the immense contained might within All For One's Quirk immediately, it starts becoming indicative of his increased power level, with Star confusedly noting his hair visibly lengthening mid-fight with her. Tomura/All For One goes on to reveal that this is a result of his body changing and adapting to find the best form to suit his immense power, even if it deviates from the standard human mold. He uses the example of hair and nails naturally growing to explain how he's able to form massive fleshy tentacles to attack everybody even with his Quirks sealed, his hair lengthening as a side-effect of him controlling his body's 'growth' as a weapon.
  • Expy: Horikoshi states that Shigaraki was based on the protagonist of his first one-shot, Tenko. They both share the ability to disintegrate anything they touch, they both accidentally killed their loved ones with their abilities, they both share an intense hatred for the world and wish to rid it of something,note  and they both share the same name.
  • Extra Digits: And boy, how. He gains the ability to grow an innumerable amount of extra digits and limbs by the time of the final battle, his body naturally evolving in response to the Quirk Singularity occurring within the All For One Quirk by generating extra body parts to compensate for it.
  • Eye Scream: Shigaraki has a scar over his right eye, revealed to be a result of clawing at his own eye after accidentally murdering his sister. Later he ends up in several fights where he's exposed to fire or explosives that rupture his eyeballs before Hyper-Regeneration makes him heal back to himself.

  • The Faceless: Initially, his face is always covered by one of his severed hands, even when he's not wearing the rest of his costume. He eventually reveals his real face to Midoriya in a shopping mall, and begins to show his face much more often as he grows in power and confidence. After the fight with the MLA, Tomura more or less does away with wearing the hands after their destruction at Re-Destro's hands ends up unlocking his suppressed traumatic memories and the full potential of his Decay with them, even pointedly destroying his 'father' hand as a sign he no longer needs to rely on them or be chained down by his past. During all his subsequent appearances, he goes without wearing any such facial coverings anymore, though he retains the sole surviving hand as part of his 'brand recognition' and his shaggy and unkept hair also helps hide his facial expressions afterwards. When he's beaten to the point of near-catatonia by the heroes' efforts during the Paranormal Liberation War arc, Spinner remembers how he stated that the hands on his body awaken his instinctual hatred towards everything and help focus him, putting the remaining hand back on his face as a means of rousing him...which unfortunately triggers All For One to assume complete control over Tomura's body through monopolising Tomura's hatred to empower his mental control over his 'protege'.
  • Fan Disservice: Downplayed, at first. Fighting against Machia for months led to Tomura developing an impressive physique, on par with Midoriya, but when he gets his shirt destroyed during his fight against Re-Destro is a bit diffucult to appreciate given his poor skincare. Played Straight during and after the PLF War arc. The strain from all the for All for One quirks on his body, combined with the damaged inflicted by the heroes during the fight on Jaku causes Shigaraki's body to rip itself apart from below his collarbone, with his left arm barely attaching itself to him. It gets worse by the time of the Final War, with his body evolving into grotesque and bizarre mutations. At one point, his back manifests a mouth to spit out the poison that Suneater infected him with.
  • Faux Affably Evil: He can be even-tempered and articulate when he so chooses, as evident in his ambush of Midoriya in the shopping mall, where he made due on his promise not to hurt him so long as they talked. He also shows shades of this in his battle in the Paranormal Liberation War, at times appearing more politely amused than truly angry. This is only whilst he's in control and can use his powers to beat the heroes down with ease however. His faux politeness goes away once Izuku starts seriously inconveniencing him with repeated blows at 100% power. Afterwards, as the merger between his and All For One's minds gets further completed, this trait manifests itself more frequently in battle, but usually in a manner befitting his master's spiteful mockery of his opponents, with occasional shades of Tomura's attitude showing in his dialogue.
  • Feel No Pain:
    • Part of Garaki's modifications to his body involved almost completely nullifying his sense of pain. After he emerges from his pod, Shigaraki ignores almost all the injuries he suffers, relentlessly attacking his opponents and relying on his Healing Factor to fix the damage. Once the damage his incomplete body endures starts becoming too much for it, resulting in a large, bloody gash appearing in his torso and his right arm almost falling off, Shigaraki's only reaction is a confused "huh?", and to calmly analyze why his body is suddenly falling apart instead of freak out.
    • Later, his diminished pain receptors leave him wholly unprepared to feel even the slightest "sting" from the heroes stacking damage on his body with his Quirks once again turned off. He and All For One undergo a simultaneous Villainous Breakdown in response, further bolstered by his Tenko aspect's indignation over being ignored when he needed saving.
  • Fighting from the Inside: Shigaraki might end up under All For One's control, but Tenko doesn't. Tenko comes into being after All For One starts absorbing Tomura, with the scared young boy pleading for Izuku to come save him from becoming bound to the supervillain. While at first his attempts at resistance amount to little, the heroes attacking their shared body combined with Tenko's righteous fury over nobody ever bothering to help him when he needed it result in him fighting off All For One in tandem with Izuku beating the snot out of him.
  • Final Boss: Built up as one. Being a direct Evil Counterpart to Midoriya, he becomes far and away the antagonist with the most Character Development on top of being the most dangerous and powerful, even surpassing All For One. The entire story of My Hero Academia arguably comes down to him and Midoriya settling the differences between them, both ideological and circumstantial, to deal with society's core issues once and for all. Not even All For One attempting a Fusion Dance to steal his thunder can change this being his destiny, as Shigaraki throws off the attempt and seizes the All For One Quirk entirely for himself so he may destroy the world of heroes, with Midoriya now at the top of his list.
  • Fingore: Re-Destro cripples Shigaraki's left hand, destroying his thumb, index and middle fingers. This winds up becoming a Power Limiter on him going forward, as whilst Shigaraki unlocks the full ability of his Decay quirk shortly afterwards and can unleash it in an AOE wave around him to crumble entire cities to dust in seconds, his quirk activating through his fingers and the strain involved means he can only perform this with his unmaimed hand. Izuku utilizes this weakness against him when his body starts breaking apart during their fight and his arm nearly falls off entirely, using the brief window made by Shigaraki trying to position his arm in place to yank him skyward with his Combo Platter Powers. Having apparently learned from the experience, Shigaraki later starts overclocking his Healing Factor to regrow his missing digits to overcome this disadvantage, succeeding in creating tiny nubs of his missing fingers after some unpleasant side effects.
  • Foil: To Midoriya:
    • Both of them are the pupils of the previous Big Good and Big Bad, and at the start of the story both of them are pretty terrible at what they do and have to learn from their mentors.
    • Shigaraki is descended from a user of One For All but doesn't know it, while Midoriya has no biological relationship to any of the Quirk's users but has a strong father-son dynamic with All Might. Both Midoriya and Shigaraki also belong to Nana Shimura's legacy in similarly indirect but connected ways to All For One, who is interested in them both to juxtapose the Symbol of Peace with a Symbol of Fear.
    • And while both have powerful Quirks they need to control for fear of what could happen otherwise, Midoriya works to control his power in increasing increments and fears the damage his Quirk does to his own body, while Shigaraki's can only be all-or-nothing and affects things around him when uncontrolled.
    • Even their Body Motifs are opposing, with Shigaraki requiring his hands for his Quirk and Midoriya focusing his own through his legs after developing Shoot Style (though still occasionally using his fingers and arms in a pinch).
    • Both inherit their mentors' Quirks through different ways: Shigaraki obtained All For One after undergoing a painful, extensive Quirk surgery and his body is artificially enhanced to imitate All Might's immense strength (although not completely on par with All Might), and he makes a point of regularly comparing his base physical feats to All Might in his prime as his 'evolution' continues. On the other hand, Midoriya obtained One For All after undergoing ten months of rigorous, but ordinary, physical training. He also obtained the ability to wield multiple Quirks, which imitates All For One's ability.
  • For the Evulz: At first, he comes across as a Manchild who just wants to destroy what he dislikes. Many villains even criticize him for this. Gradually, Shigaraki realizes his conviction: that too many heroes have spoiled society, and therefore the entire society must perish.
  • Forgot About His Powers: Literally. After killing his family with his Quirk, he suppressed the memories and subconsciously held himself back. Upon gaining said memories back through his resulting mental breakdown after his family's hands are destroyed in battle, and finally coming to terms with what he'd done thanks to his increased maturity, he becomes capable of spreading decay through contact like a virus, increasing his danger level exponentially, to the point the heroes need Erasure used on him afterwards to stop him killing anything around him in a second.
  • Four Is Death: In My Hero One's Justice, hitting an opponent with his special move four times kills them instantly. The pop-up that appears upon connecting displays a number that increases with each hit, until the fourth one, which says "DEAD!". Also, his birthday is April 4th, or 4/4.
  • Freak Out: When Re-Destro starts damaging the hands of his family, Shigaraki starts having a mental breakdown as this triggers his repressed memories of his family.
  • Freudian Excuse: We get glimpses of his childhood, and it's really sad. By all accounts, he had a loving family before his Quirk awoke except for his father who despised heroes due to his mother abandoning him. He got into trouble with his father whenever he expressed a desire to become a hero and was locked outside until he apologised. While his family loved him, they didn't want to go against his father's wishes, and tried to convince him to give up on his dream, which left him constantly depressed. His sister Hana was the only one to encourage Tenko and showed him a picture of his grandma Nana to give him hope. However, his father found out about the photo and Hana, in a Moment of Weakness, blamed Tenko, which led to his father beating him. Seeing that his family wouldn't stand up for him was the final straw and it led to Tenko's Quirk awakening. He was left lost, destitute and crying in a street alley. Why did no one help him? Because he looked so freaking scary. But then All For One came to his rescue...
  • Friendless Background: Mirio calls him out on having no real attachments to anybody, which drives his petty need to destroy the world. Uncharacteristically, this fazes Shigaraki long enough to let Mirio land an attack. While he did form real friendships with the League of Villains, he seems to gradually forget about them as All For One takes deeper root in his mind. However, 'Tenko Shimura', the remaining aspect of Tomura's better personality traits and childhood innocence locked away in his psyche, is roused to the forefront in Chapter 361 by said accusation, childishly claiming he did have friends when he was still Tenko, making All For One aware that he's not fully in control of Tomura's mind and body yet.
    Tomura/Tenko: I do have friends… Cuz, like, Mikkun and Tomo said, "You're really nice, Ten." And Mon likes to go on walks with me! Didja know that? Huh? So yeah, I've got friends!!
  • From Nobody to Nightmare: The mass murderer who would become known across the globe as Tomura Shigaraki was originally just some kid named Tenko Shimura. While having ties to One For All through his grandmother Nana, under different circumstances he likely wouldn't have become a criminal at all even if his Quirk still manifested the same way. Had somebody actually possessed the courage to help him, he'd never have been taken under All For One's wing and molded into a supervillain. This is visually demonstrated through the only remaining part of Tomura left after All For One assimilates his psyche — the crying childhood self of Tenko Shimura, still waiting for somebody to save him, wheres the rest of his mind and body has been thoroughly warped into an almost inhuman abomination by All For One's machinations.
  • Full-Name Basis: Kurogiri always addresses him by his full name.
  • Gave Up Too Soon: His first raid on USJ is quickly called off when their trump card against All Might lost. Midoriya calls him out on this, pointing to it as one of the major differences between him and Stain, along with their conviction. This aspect is completely averted after further character development, to the point that the heroes regularly panic over Tomura weathering things that would have killed or broken anybody else.
  • Generation Xerox: During his month and a half long battle with Gigantomachia, he kept his smile up through the whole ordeal, unwittingly following in his grandmother's footsteps.
  • A God Am I: Relishes becoming as strong as All Might even with his Quirks turned off by Erasure, and thoroughly enjoys the new powers All For One grants him as he embarks on his quest for destruction. Becomes an instance of Didn't Think This Through as he does attain god-like power, but at the cost of All For One slowly subsuming his consciousness into a superior copy of himself.
  • Good Scars, Evil Scars:
    • Has a big scratch over his right eyelid and a nasty looking disfigurement around the corner of his mouth. These were partially self-inflicted— In his horror over seeing his sister suddenly break apart into bloody chunks right in front of him when his Quirk manifested, he ended up clawing at his own face and ripped out a significant chunk of his eyelid, just barely missing giving himself an Eye Scream. When Kotaro tumbled across the massacre and Tenko's decay went berserk, breaking the ground underneath them into unstable rubble, in desperation, he grabbed a nearby weed clipper and smacked Tenko across the face with it in a blind panic to keep his son away from him, giving him his mouth scar.
    • Following the fight with The Meta Liberation Army, he loses his thumb, index and middle fingers on his left hand, which remains afterwards along with his facial scars even after he gains Hyper Regeneration and regularly sustains and recovers from much worser injuries when fighting entire armies of heroes solo.
  • Grand Theft Me: Unfortunately for him, All For One did not want to give up his Quirk in a traditional sense and is instead trying to hijack Shigaraki's body by absorbing all of his hate and animosity in a maniacal bid to steal One For All. The plan is only being interrupted because the heroes attacked Dr. Garaki before he could complete the process and meld the two seamlessly, and Shigaraki's own justified fury at this plan allowing him to fight his adoptive father off. Itself somewhat subverted as that hatred is what allows All For One to make him his slave. As of present, the more Tomura rages against him, the stronger their mental overlap becomes, resulting in a being that is both All For One and Tomura at the same time.
  • Hates Their Parent:
    • He is shown to hate his father, Kotaro, in flashbacks of his childhood. In fact, Kotaro's treatment of Shigaraki was so bad that he outright murders his father with gleeful joy when given the opportunity.
    • Says to Nana Shimura when he meets her in One For All, his own grandmother, that he hates her for everything that's happened to him too.
    • Lastly, he's even come to hate All For One for stealing his body, which is very understandable. Note that All For One relishes this unlike the previous examples as this was all part of his plan to stoke enough anger in him to steal One For All. Meaning all of Shigaraki's torment ultimately comes from the authority figures in his life failing him time and time again.
  • He's Back!: After roughly two years of manga chapters showing him sparring with All For One over control of his body, the real Shigaraki comes back just as the tide turns in favor of the villains' side in the Final Battle.
  • Healing Factor:
    • After gaining the original All For One Quirk, he also gains the Nomus' signature Super Regeneration. He relies on it more than all of his other Quirks combined, surviving Endeavor's many fire attacks and even a 100% beatdown from Midoriya, although he's left severely overburdened since his body hadn't reached full compatibility with All For One yet. Later against Star and Stripe, he performs an even more miraculous feat by recovering from having ten missiles detonated on him at once.
    • This, along with his accumulated powers, is immediately cut off by the heroes the first chance they get by the Final Battle, but by then they run into a different set of problems, as his nearly-perfected body is now almost-impossible to meaningfully damage at all. His new ability to cancerously grow his flesh to attack with also plays into this, as he simply regrows any damaged parts the heroes manage to tear off his appendages.
  • The Heavy: For all intents and purposes, he is the one stirring up trouble in the series, with the rarely-appearing "Sensei" supporting him by providing intel and manpower. This changes following his mentor's imprisonment.
  • Helping Hands: Has hands covering his entire body, including his face. It's later revealed these hands are all that remains of his family after his Quirk awakened. Following the Paranormal Liberation War, only Nana's hand, now burned black by Endevour's firepower, remains.
  • Hero Killer: The massive Decay wave Shigaraki unleashes upon awakening in Jakku hospital kills a good number of the heroes there, among them X-Less and Crust. He also manages to kill Star and Stripe, the number one ranked pro hero from America, capital of superheroes.
  • Holding Out for a Hero: Shigaraki shows contempt for this attitude during his conversation with Midoriya. In his eyes, everyday people are oblivious to the fact that anyone with a dangerous Quirk could easily kill them. He also thinks this is because the masses believe that heroes like All Might will always jump in and save them. It's implied that the latter attitude also created the Bystander Syndrome that made people so unwilling to help Shigaraki when he was a child. Ironically, it's later revealed that inside his mindscape, part of him is still actually doing this, symbolised by a vision of his crying childhood self hugging Mon outside his abusive family home, which Izuku catches a glimpse of during their mental tug-of-war over One For All, It is implied to be tied to the root cause of his endless hatred for everything, that nobody even attempts to save him from his own pain, even as his present-day self has committed so much death that practically nobody is interested in doing anything less than killing him to end his immense threat for good. This childhood self later becomes the focal point of Tomura's psyche that retains its individuality after All For One starts assimilating their minds together, because it is tied to his positive desire for a hero to appear and save him, meaning All For One is completely blind to its existence.
  • Horrible Judge of Character: He badly underestimates Bakugo's moral character when he targets him as a potential Rival Turned Evil.
  • Humanoid Abomination: The procedure he underwent has granted him inhuman amounts of power under a normal appearance. Even with his Quirk nullified, his strength is comparable to All Might. Becomes more pronounced once he employs his new Body Horror abilities that make him more like a man-made Thing, sprouting and retracting thick masses of hands and fingers that can even form mouths for extra attack options. It's incredibly disturbing, to say the least.
  • Hypocritical Humor: When Toga and Dabi attempt to join the organization, he calls Toga a "brat" and gets annoyed at Dabi for not revealing his real name. Mentally speaking, Shigaraki is more of a "brat" than Toga is, and is also not going by his real name.
  • I Control My Minions Through...: Pure authority initially, and not even his own. However, after All For One's defeat and his subsequent Character Development, he shifts more toward loyalty based on acceptance and benevolence. This proves a contrast to his master's ruthless treatment of his own 'allies' as benefits himself at their expense, to the point that Spinner can easily tell Tomura's absent when All For One possesses his body because of how differently he treats his allies.
  • Identical Grandson: As Chapter 235 shows, when Tenko was five years old and hadn't yet developed his Quirk, he much more closely resembled his grandmother, Nana, with the same black hair, eyes, and beauty mark.
  • Implacable Man: Following his upgrade by Dr. Garaki, he's become this thanks to his utterly ridiculous Healing Factor, and best shown in his fight against Star and Stripes. He takes physical blows from a gigantic Fighting Spirit, gets stabbed by a laser blade on the level of Surtr on Hela, and gets multiple tactical ICBM dropped on him. None of these manage to stop him for prolonged period, and he just keeps on ticking. By the time of the Final Battle, his main body has become so tough, in addition to his healing, that it's almost impossible to break his skin, and only Bakugou's focused explosions manage to damage him enough to leave a lasting mark- and even that doesn't slow him down in the slightest.
  • Important Haircut: After abandoning his past, his normally droopy and wet-looking hair becomes free-flowing and silky instead, accentuating his new, intimidating appearance and status. It later turn out to be capable of growing to visibly longer lengths mid-battle, as Star confusedly notes during their fight as he summons more power from his accumulated Quirks against her, acting almost as a visual indicator of his growing power. This is later revealed during the Final Battle to be a side-effect of his body being forced to adapt to contain the immense power of All For One, driving Tomura to become capable of mutating himself through 'growth', akin to how hair and nails naturally grow longer, to have his 'vessel' adapt to suit his now near-godlike abilities.
  • In a Single Bound: Once awakened from an intense medical procedure designed to improve his body dramatically and implant the original All For One Quirk, Shigaraki gains the ability to leap long distances from his sheer Super Strength, making him highly mobile and dangerous even without the ability to use decay on command.
  • Insane Troll Logic: Initially prone to this, making speeches about how heroes are just as bad as villains and the like. This makes him a charismatic leader to the two-bit thugs following him during the USJ Arc, given that he's basically telling them what they already want to hear.
  • Instant Expert: Right after awakening from stasis, Shigaraki knows what Quirks he has, and can wield them without any blowback or initial struggle. The only thing he needs to do is decide what Quirks would work best. This was intentional on All For One's part, as he chose Quirks that would be rather straightforward and easy-to-use when first obtained, something he himself shows a preference for in his original body. That said, Tomura's instant acclimation to more complex Quirks like Ragdoll's 'Search'' to find Izuku instantly is implied to be an early sign of All For One's vestige beginning to merge into Tomura's psyche, along with the knowledge of how to use all the stockpiled Quirks.
  • It's All About Me: Initially, his reasons for going against hero society are purely solipsistic, because he sees taking out his hatred of it for "kicking him to the curb" as a form of validation of his own power. He gets called out for his childish motivations by Stain in the Hero Killer Arc, and later averts it after Character Development. He still wants to tear society down mainly for his personal inherent hatred of it, but he now modifies his motivations to be for the sake of allowing his allies in the league to build something better from the rubble after he's finished, even implying that he doesn't personally expect to live long enough to see the outcome of his efforts and is satisfied as long as they live freely because of his actions. This divergence in motivation is one of the reasons part of Tomura can retain its individuality after All For One begins merging their minds together, as the more self-centred All For One cannot fathom any positive qualities or emotions in others, meaning Tomura's selfless desire to aid his allies at his own expense cannot overlap with his master's thoughts.
  • Kick Them While They Are Down:
    • Overlaps with Kick the Son of a Bitch. After Midoriya defeated Overhaul with the help of Eri, Shigaraki stages an attack on the escort the villain is in, to punish him for the dishonor and bloodshed he inflicted on the League of Villains.
      Shigaraki: Just like that, you're helpless! A weak, Quirkless loser! And the fruits of your labors belong to me! Now, you don't even have a thumb to suck on! You're doomed to watch from the sidelines as your dream falls apart! Let's do our best!
    • He has a more ruthless repeat performance in the movie Heroes: Rising where after Nine is beaten and severely injured in a fight against Midoriya and Bakugo, Shigaraki appears before Nine when he's at his weakest and kills him with his Decay Quirk.
  • Kick the Son of a Bitch:
    • His destruction of Overhaul's arms before taking the completed Anti-Quirk drug, meaning everything Overhaul did was ultimately for nothing. Considering all the abuse and torture Overhaul inflicted on Eri, it's hard to not feel some sense of gratification.
    • He killed his father for all the abuse he inflicted on Tomura due to his anger towards his own mother and heroes in general.
    • As the Final Battle goes along his 'Tenko' persona resisting All For one's Split-Personality Merge of their psyche starts to become more and more of a problem for the Diabolical Mastermind, compounded by the fact that the physical damage dealt to him to further fracturing their fused mentality. This furthers All For One's Humiliation Conga as he steadily loses a battle fought on two fronts despite the immense power he wields through Tomura's body, culminating in the 'Tomura' personality violently resurfacing and seizing control. The visuals and the Second user's observation of the mental battle imply it was an extremely painful process for All For One, further emphasised by the fact he desires to control the outcome of the fight to the last detail, and now he's been pushed into the background of his own climatic battle with One For All. Tomura meanwhile, essentially dismisses his master's will as irrelevant, claiming that he is Izuku's villain, and the fight is between the pair of them alone. It's immensely cathartic to see him regain control after his master tried to dominate his very being for his own gain.
  • Knight of Cerebus: The tone of the series uniformly darkens whenever he is in focus. Tellingly, his character development causes this effect to increase as well. By the time of the Final Battle, he is presented as the biggest threat period on the Villain's side and the main reason why the heroes' efforts to finish things on a united front could fail, outstripping even his master's original body, with his only real opposition from anything coming from Izuku and One For All. Thankfully, the self-same Character Development he went through has also increased his bonds and positive qualities with the league as much as they improved him as a dangerous and effective villain, which proves to be a crucial difference between himself and his master, preventing their Split-Personality Merge from being fully completed and leaving him with handicaps that prevent their situation from being too hopeless.
  • Lack of Empathy: Mired in his hatred of society at large, Shigaraki is largely devoid of genuine compassion, though he grows genuine fondness for the League of Villains as time wears on. This lack of care for those around him was deliberately fostered in him by All For One to distort Nana's biological legacy into a twisted mirror of her own heroic achievements on the side of villainy, as well as turn Tomura into a Living Weapon that All For One could possess and control as an energy source of limitless hatred that could overpower One For All and allow him to finally steal it. Tellingly, it seems that Tomura's positive development with the league was outside All For One's calculations, and proves to be a dividing point between their minds that enables part of Tomura' to retain his individuality agaisnt his Master's.
  • The Law of Diminishing Defensive Effort: Shigaraki/All For One doesn't bother dodging or blocking most of the heroes attacks during the final showdown, believing them incapable of harming him. This is Deconstructed when he realizes too late that while the attacks were individually doing much damage, his Healing Factor being disabled means they were piling up. He doesn't notice until the effects actually start effecting him and is left in disbelief it's possible.
  • Like Father, Like Son: Ironically, despite having hated his father, Tenko grew up to be very much like him: both hate hero society, both escalate to violence when things don't go their way and both grew up resenting their parents. The difference is that Shigaraki at least cares for his comrades, promising them freedom to fulfill their dreams. On the other hand, Kotaro was overbearing towards his family.
  • Logical Weakness:
    • His Decay Quirk is exceptionally dangerous, but the object he grabs has to be solid. That's why Snatch, whose ability to turn into sand gives him a fluid form Shigaraki can't properly grip, is able to fight him hand-to-hand without issue.
    • His Decay can spread through things... but only if they're touching something. During the finale, the heroes tailor-made a battlefield for him involves plenty of floating platforms that are constantly being replaced so he can't spread Decay Wave through anything.
  • Long-Haired Pretty Boy: He's still rather crusty-looking with several nasty scars, but as his hair grows he takes on a far more appealing and ethereal appearance, which is helped by his hair turning a silky, pure white after his awakening. His hair actually gets longer and longer as he draws on more power from his 'evolution', eventually growing long enough to hang down his entire back.
  • Long-Lost Relative: Shigaraki is actually the grandson of Nana Shimura, All Might's mentor and the previous wielder of One For All.
  • Made of Iron: Although his Quirk has nothing to do with his physical durability, he has repeatedly been shown to quickly recover from injuries that would be hard for a normal human to survive. He gets hit point blank by one of Bakugo's explosions and walks it off. He's also able to heal perfectly fine after being pelted with bullets in the USJ attack. Also, despite getting pummeled by Gigantomachia for a month, he's able to walk, talk, and move with fluidity. He later gets caught by a glancing strike from Re-Destro's 80% Stress form, which is strong enough to demolish buildings from air force alone, but has enough strength to get up immediately (note that this is shortly after being thrashed by Gigantomachia). In the Paranormal Liberation War Arc, Shigaraki's body is modified to grant him immense superhuman strength, speed, and durability, which combined with "Super Regeneration" allow him to survive hits that would kill most living beings. He takes large explosions from Bakugo, direct hits from Endeavor's super moves, 100% One For All blows and still manages to keep fighting. By the time the Final Battle rolls around, Tomura's toughness has upgraded to Nigh Invulerable, as Mirio's direct attacks with Nejire's spirals barely scuff his skin, let alone break it, and it's made clear only One For All's immense power has a chance of penetrating his defences anymore. However, this is Subverted, as it turns out the damage actually was piling up without Hyper Regeneration to heal it and Shigaraki simply thought it wasn't.
  • Major Injury Underreaction: Shigaraki seems to have a ridiculously high pain threshold, and barely reacts to potentially crippling injuries. He gets stabbed in the shoulder by Stain, but only reacts violently when the latter's sword touches his father's hand, and merely complains afterwards that he had only just finished healing from his prior injuries. During the battle with the Meta Liberation Army, Re-Destro destroys three of the fingers on his left hand, but Shigaraki barely notices, having a much bigger reaction to seeing his sister's hand being destroyed. After he gets modified, it's unclear if he can even feel pain anymore, or if his nonchalant reaction to the horrific damage his body endures is due to Shigaraki now having a body that can endure his self-destructive mindset. This actually backfires on him in the final fight, as his lack of reaction to injuries and belief in his own durability results in the damage he's taking starting to pile up thanks to Hyper Regeneration being negated without him realizing it until it actually starts effecting him.
  • Make Them Rot: His Quirk. He can effectively destroy anything he touches.
  • The Man in Front of the Man: All For One employs him as The Dragon and later intends for him to remain a Soul Jar for his vestige to continue his reign as a "Demon Lord" through Grand Theft Me. However, Shigaraki has none of it and reveals to his master he was planning for the long term and waiting for an opportunity to seize back control, becoming the series' overall Big Bad and booting All For One into the status of Big Bad Wannabe.
  • Meaningful Rename:
    • "Tomura Shigaraki" isn't his birth name. That would be Tenko Shimura, which gains significance when it's revealed he's the grandson of All Might's mentor, Nana Shimura. This rename was All For One's idea, and he explains it's meaning: Tomura is short for Tomurau, which means "to mourn" and invokes the sadness that comes with death and parting; Shigaraki is All For One's true last name. Thus "Tomura Shigaraki" is born as someone who inspires acts of mourning around the world as All For One's successor and surrogate son.
    • It also become more meaningful as his Split-Personality Merge with All for One starts achieving completion. Within Tomura's fractured psyche, his mental self becomes divided into his present-day look of 'Tomura' and his past look pre-Quirk awakening as 'Tenko', which becomes indicative of his suppressed good nature underneath all his trauma and misanthropy. 'Tomura' is easily assimilated by All For One's psyche without any way to resist because he has been fashioned since childhood into a Living Weapon fuelled by The Power of Hate as a source of strength, which becomes a connecting point for All For One's merging of their minds. However 'Tenko', representative of who he truly was before All For One exploited him and his traumatic circumstances can resist his assimilation and retain his identity, symbolising how Tenko isn't naturally the kind of evil monster he was twisted into becoming, and both names serving to differentiate who he was before and after becoming a pawn in All For One's plans.
  • Mind Hive:
    • After All For One passes on his Quirk to Shigaraki, it's revealed that the All For One Quirk also passes on its wielder's "will", with a ghostly apparition of All For One now existing inside of Shigaraki. This isn't a good thing for Shigaraki: because All For One can suppress his will and hijack his body. In contrast, the users of One For All and Midoriya support each other unconditionally.
    • It goes even further than that, as Tomura's own mind has been further fractured as a result of his traumatic circumstances and ongoing mental battle with his master into two distinct individuals, one representing his present-day self of 'Tomura', the other his more innocent, past childhood as 'Tenko'. Each other embodies as different aspect of Tomura's mentality, his 'good' and 'bad' sides, and whsilt the 'Tomura' aspect is one-sidedly assimilated into All For One because he has been groomed into knowing nothing except The Power of Hate for that very purpose, 'Tenko' can resist and retain his individuality because he remembers the better happier moments that Tomura did have, despite his overall traumatic life. This leads to All For One being genuinely taken aback that a piece of Tomura's psyche yet remains separate from him and can resist his command of the body. This gets worse when the Final Battle gradually causes the mental fusion to fall apart and cause Tomura and the Vestige to split.
  • Misanthrope Supreme: In stark opposition to Izuku's All-Loving Hero, Shigaraki believes the world is beyond all redemption and that the heroes are all glory hounds and carelessly violent enforcers who care nothing for the weak if they don't stand to benefit from it. While his convictions are hazy at first and his methods unforgivably evil, it's eventually proven he's not entirely wrong.
  • Momma's Boy: Flashbacks shows that he was close to his mother, Nao, before her death.
  • Moral Myopia: While he isn't entirely wrong about the myriad of social issues that fester within hero society, his use of mass wholesale destruction as a solution has had the effect of replicating the root cause behind those issues on a larger scale. All For One basically invoked this mentality into him mainly for the purposes of using his hatred to facilitate their mental fusion, so he could then assume control of Tomura's younger body and stronger willpower and control him to enact his ambitions to Take Over the World, meaning he groomed Tomura for the sole purposes of being an utterly destructive Living Weapon for his plans without intending he gain greater ambitions than that, because All For One's ambitions would become his.
  • Mouth of Sauron: As of the Paranormal Liberation War Arc, he's effectively become this for his master and mentor All For One, and he's not too happy about it either.
  • Mr. Fanservice: In the Paranormal Liberation War, he ditches his top and while his face is disheveled, his physique is comparable to Deku's.
  • Murder in the Family: The Meta Liberation Army arc reveals that when Tomura first awakened Decay, his lack of control over its 'spreading' effect accidentally lead to the deaths of his entire family, save for his father, whom he used it to deliberately kill in a fit of anger.
  • Muscles Are Meaningful: As it turns out, Dr. Garaki didn't only transfer All For One to Shigaraki during his enhancement process, but also physically strengthened his body as well. After awakening from his long slumber, the formerly slim Shigaraki is now absolutely jacked and it shows in his performance; his raw power is now such that, even while having his Quirks cancelled out by Aizawa, he can easily jump several stories in the air and casually overpower Endeavor with one arm. This is somewhat ironic though, as he was previously a case of Muscles Are Meaningless and was already quite a bit stronger than his slim build suggested.
  • My Significance Sense Is Tingling: After acquiring the All For One Quirk, Shigaraki also inherits his master's intense urge to obtain One For All. This is the first sign that his consciousness is no longer all his.
  • Mystical White Hair: The color of Tomura's awakened hair is rather signifigant. It isn't just white like Dabi's, it's glowing. Shigaraki's hair is a visual indicator of his power because it's constantly shining and shimmering after his power-up during the My Villain Academia arc. This is intentional too, compare his white/light colored hair from before the arc with it during.
  • Nervous Tics: He often scratches his neck whenever he's stressed or pissed off. However, he does it much less now after his character development.
  • Never My Fault: For his understandably tragic backstory and chilling monologue in the Paranormal Liberation War, Shigaraki is ultimately a man who refuses to address his weaknesses, blames the rest of the world for his failings and uses the aforementioned tragic backstory as a justification for his malice. Because of his mentor All For One's influence, he is unable to entertain the possibility that he's wrong about anything.
  • Next Tier Power-Up:
    • He gets this during the fight against the MLA when he unlocks his long-suppressed memories and regains the full use of his Quirk, allowing his Decay to propagate between objects and people rather than being limited to what he directly touches.
    • He invokes this deliberately when he orders Dr. Garaki to upgrade him using research originally meant for All For One, which results in Shigaraki gaining not only more control over Decay, but a greatly improved body and the All For One Quirk along with the stolen Quirks that came with it. Even when he's prevented from using his Quirks, the base enhancements to his body mean he's still a Lighting Bruiser comparable to All Might in his prime, paired with his intense determination, and refusal to stay down for long to make him into a nigh-unbeatable force. The only thing that can give him pause at that point is Izuku, and even then, he has to resort to using the full 100% force attacks of One For All in rapid succession to do any meaningful damage to him.
    • He again invokes this before the Final Battle, partially under All For One's direction, as he's forced to spend the in-between time completing his biological remodelling though sheer force of willpower to finish 'evolving' into the next stage of humanity and become 'the Perfect Demon Lord' All For One envisions. This means in addition to be being even tougher and stronger in a fight, he has the ability to control his body's growth, sprouting cancerous amalgamations of fingers from his maimed hand as Combat Tentacles against the heroes, and his body adapting to any attempts they make to weaken him, like poison. All For One, speaking through him, explains that this is because the body is naturally adapting to find the most suitable form for all the immense power continued with All For One's Quirk, as it's simply too much power for the human template to fully withstand.
  • Nightmare Face: There are entire pages dedicated to how creepy this guy looks, just to hammer in the point. The first time we see his actual face, which should be comparatively normal, it's drawn with frightening detail. In fact, it's for this reason that people didn't want to save him or even look at him for that matter when he was a child.
  • No Brows: A subtler example, likely for the uncanniness. While Shigaraki's bangs and/or hands generally cover his forehead, certain panels (usually action shots) show that the wrinkled skin texture around his eyes continues all the way up to his hairline, including the area where his eyebrows should be. He had them as a little boy, so the implication may be that he's somehow scratched them off.
  • Oh, Crap!: When he searched for All For One's legacy and that legacy found him first, wanting Shigaraki to prove himself worthy of his devotion.
  • Omnicidal Maniac: His overall goal appears to be the destruction of society. It is later revealed that this is due to the immense trauma he had suffered during his childhood when his Quirk had first manifested. Shigaraki can only recollect fragments that excruciatingly torment his psyche. As a result, he loathes the world and every living thing in it:
    Shigaraki: Even if this society comes crashing down... Even if I rise to rule the underworld... That weight in my heart is never gonna go away. It's why I hate everything. Every living, breathing thing just rubs me the wrong way. So why not destroy it all? Why not destroy everything?
  • One-Man Army: Tomura Shigaraki has the potential to kill many people, but he finally comes into his own as this in the battle against the Meta Liberation Army, capable of sweeping away entire crowds of people with a single blow, his Decay spreading between people. When his Quirks are stockpiled, it allows him to challenge countless Heroes, and even without that his biological remodelling makes him a Lightning Bruiser comparable to All might in his prime, meaning all shutting off his Quirks does is force him to deal with heroes one-by-one, rather than taking out hundreds of them in a single move.
  • The Only One Allowed to Defeat You: When his 'Tomura' persona finally resurfaces after all the damage dealt to the TomurAFO fusion mental and physically, he emphasises this is the case between himself and Izuku. He claims that he is 'Izuku's villain' showcasing a desire to fight and kill him himself rather than allow his master to interfere in their showdown. This noticeably contrasts against All For One's perception of Izuku as a mere vessel for One For All's power, demonstrating respect towards Izuku as a person, even if he's diametrically opposed to him.
  • Overly Long Scream: Played for Drama when Tomura gruesomely kills Kotaro.
  • Person of Mass Destruction:
    • While the audience only gets to see bits and pieces of how powerful Shigaraki's Decay Quirk really is, the League's war with the Meta Liberation Army showcases some truly jaw-dropping levels of power, which includes disintegrating dozens of members of the army with the sweep of a hand and destroying an entire tower just by touching it, and later on disintegrating an entire city leaving only cratered ruins. It is later revealed that the destruction was even greater than what occurred at Kamino.
    • After awakening from stasis with the All For One Quirk transplanted into him, Shigaraki is universally acknowledged as this. The first thing he does after waking up is decay a third of Kyoto city, killing numerous civilians and heroes. The heroes have no option but to use Erasure to limit his threat level, and even handicapped like that, he's still strong and powerful enough to give the heroes an extensive beatdown by himself, with the fighting turning into a Race Against the Clock for them to defeat him for good before he outlasts everything they throw at him. The one battle he has fully access to all his abilities with is against a Reality Warper, who hits him with attacks powerful enough to alter the landscape if they weren't fighting over the ocean, and he's still presented as an overpowering threat that ends the fighting with her the second he gets his hands on her.
  • Personality Powers:
    • Actually discussed between him and Re-Destro. Shigaraki is an extreme nihilist that cares for nothing but the destruction of the world. Re-Destro is aware of this, which is why, as a Visionary Villain, he initially opposes the League.
    • This is invoked by All For One while he steals Quirks to "pre-load" for Shigaraki before passing on the original All For One Quirk. Knowing that Shigaraki desires absolute destructive power and also wouldn't be patient enough to train any Weak, but Skilled type of powers, he steals simple but powerful Quirks for his protégé to use, such as Super Strength multipliers and air cannons.
    • During the Final Battle the Quirk Singularity causes his modified body to begin seeking its "ideal form" in order to combat the heroes. The narration in chapter 366 notes that originally his ideal form seemed to be a giant, bloated mass of fingers, seeking destruction, a form that overwhelmed the world and kept everyone at arm's reach. But after he is pushed into a corner by the heroes, his body morphs so that the various fingers he generated wrap around himself, forming a protective shell, whilst the faces of people that influenced him in his life (his family he killed and the old woman who didn't help him) wraps around his left arm to gigantify it. This gives him a defense focused body that enhances his already formidable strength which Best Jeanist theorises represents his desire to reject everything.
  • Playing Both Sides:
    • His plan for the Meta Liberation Army. Gigantomachia will sleep for about one hour more than they will be in the city trying to rescue Giran. Shigaraki's plan is for them to hold on, get Giran to safety and attract Gigantomachia to the city. Giganto will destroy the army to the same degree that they'll hopefully tire or harm him enough for Shigaraki to be able to take him down himself, killing two bird with one stone. Dr. Garaki points out the army may be lying about their numbers but in that case, Shigaraki is satisfied with the idea that Gigantomachia will obliterate the little numbers the army does have.
    • Employs this tactic again during the Final Battle. He gives up trying to fight All For One for control of their shared body to instead wait and take root inside his master until such a time as the balance between their Fusion Dance is interrupted by the heroes fighting him. He holds All For One up gradually, but just enough that his master's plan starts derailing with the right prodding. This "fissure" grows and grows as Shig AFO sustains damage, with Midoriya giving him such a brutal Curb-Stomp Battle it allows Shigaraki to wrest back control. A successive attack from Lady Nagant infuriates All For One further and prompts Shigaraki to finally destroy his vestige and reclaim his rightful place as the story's true Big Bad.
  • Power Makes Your Hair Grow: His hair grows longer and longer throughout the story as he gains more experience and undergoes his Character Development. By the time he acquires the All For One Quirk, he has some splendidly silky white locks of hair indeed. And as noted during his battle against Star and Stripe, his hair grows longer with each jump in power he achieves. His hair by the final arc is the length of his entire body.
  • The Power of Hate: His desire for destruction stems from loathing towards society as a whole, channeled into rage that drives his Quirk's abilities: he wants to wipe out what he hates. Hatred specifically motivates him against All Might and Midoriya, the former as a symbol of the society he hates (and for hurting his mentor), and the latter for aspiring to All Might's example. Hawks speculates that All For One more or less invoked this mindset in Shigaraki's upbringing to ensure his success at stealing One For All.
  • Power Palms: After obtaining "All For One," he gains holes in the palms of his hands like his master.
  • Power Parasite: He obtains All For One's original Quirk thanks to Dr. Garaki. However, ironically, it turns out the ultimate goal of him doing so was so the Quirk could parasitise him, and the vestige of his master attached to it could forcibly integrate itself into Tomura's Psyche and undergo a Split-Personality Merge into a new, younger being that was both and neither of them at once, enabling him to both be 'reborn' as a 'perfected Demon Lord' as per his long-held ambition, as well as finally have the means for monopolising Tomura's sheer all-encompassing hatred both to secure their mental fusion and successfully overpower One For All in a battle of wills, enabling him to finally steal the one Quirk that could rest All For One's signature power.
  • Psychopathic Manchild:
    • Initially starts out as one of these, seeing the whole USJ invasion as nothing more than a game. All Might later specifically describes him as this. Stain and Overhaul even call him out on this, finding the reasons for his actions and his ambitions childish and without cause. He eventually grows out of this by the end of the Internship Arc; the only trait he does still have from this is his inability/ refusal to process his actions being wrong and how they affect people around him.
    • Taken to a literal extreme by the time of the Final Battle. His hate-filled, 'Tomura' half of his psyche is supposedly completely absorbed into All For One's by the time he appears to steal One For All for good from Izuku, preventing the heroes from being able to exploit any mental weakness he might have had. However, the good part of him, represented by his childhood self of 'Tenko Shimura, was able to resist the absorption and retain its individuality because All For One is completely blind to such concepts. This means that the only aspect of Tomura that is still him is a literal child, trapped inside his mind with the psychotic TomurAFO amalgamation, which results in 'Tomura' giving a extremely childish retort to Miro's accusation that he never had friends which upsets 'Tenko', taking them both off guard with his strange mannerisms.

    R - X 
  • Rage-Breaking Point: In the past when his Quirk first emerged and killed his family. He had been trying to get help from his father after accidentally killing the rest of the family when his father hit him in the face with a weed whacker. This act, reminding him of all the abuse he had taken under his father's household, awakened a desire to kill his father in murderous rage, making him his first actual victim in the process.
  • Razor-Sharp Hand: In Chapter 281, he incapacitates Gran Torino by running his fist straight through him, though that was more due to his Super Strength than anything, and the messy hole he gores in his abdomen bears little resemblance to the usual wounds inflicted by the trope.
  • "The Reason You Suck" Speech: Doubles as Calling the Old Man Out. He tears All For One apart with words alone during his Eviler than Thou moment, calling him out for being so arrogant as to think he could manipulate and toy with people without suffering dire retribution, and aptly describes it as no different from how he tried to groom him into his perfect vessel. Then Shigaraki proceeds to tear his metaphysical vestige apart by exploding out of him like a coccoon, calling back to the butterly imagery often associated with him.
    Shigaraki: Ha ha! Manipulating [Lady Nagant's] emotions and history didn't work, huh? Yeesh, look at you now! That's what you get for sticking your hands where they don't belong! The same goes for the way you groomed me. Using Shimura and All Might to push my buttons like that. All to move ahead with your plot to hijack my body and soul to make use of my burning rage to take One For All for yourself.
  • Red and Black and Evil All Over: His default color scheme. First he wears black shirt, pants and a longcoat with a pair of red sneakers. Later on, he dones a long red cape with a black jumpsuit and shoes.
  • Red Eyes, Take Warning: Made more visible when he has no hand on his face.
  • Red Right Hand: After his battle with Re-Destro, Shigaraki loses all but the ring and pinkie fingers of his left hand and now wears a prosthetic that resembles a half glove over his fingers.
  • Redemption Rejection: The little boy inside Tomura that Izuku sensed happens to be just as evil as the rest of him, and Tomura establishes he and "Tenko" share the same goal of ultimate destruction. Accomplishing that dream is the one thing he truly desires. Yet even saying that and knowing he'll almost certainly have to put him down, Izuku proclaims he can't ignore he was crying.
    Shigaraki: As Tomura Shigaraki and Tenko Shimura I've got just one hope. The destruction of everything stemming from that house. That's the only thing that's gonna save me, hero.
  • Repressed Memories: Shigaraki subconsciously suppressed his memories of him killing his family as a self-preservation measure. Once those become unlocked, Shigaraki is capable of showing what he can really do —reduce an entire city to a dust-filled crater in minutes.
  • Replacement Goldfish: It's implied he's one for his foster father since Shigaraki has an eerily similar resemblance to All For One's younger brother. All For One actually intended for Tomura to 'replace' himself entirely, considering his old body and original self expendable over Tomura's own, which, given All For One's utter obsession with Yoichi's Quirk, raises disturbing implications over All For One's intent to 'become' Tomura and gain his brother's Quirk through him, effectively becoming an image of Yoichi if he'd joined All For One.
  • The Resenter: To Stain for upstaging him as a villain without even trying. He doesn't react well when the new recruits admit that they only joined the League of Villains because they are fans of Stain. Kurogiri's intervention is the only reason he and the new recruits didn't kill each other on the spot.
  • Roaring Rampage of Revenge: His M.O. across the story boils down to this. Even before he focuses on any discernible goal, Shigaraki's primary motivation is to cause chaos and suffering no matter what so everybody feels the same misery he experiences constantly. This is him getting back at the society that created him, first by giving him hope he could be a hero only to cruelly rip it away once his Quirk manifested. Then leaving him to fend for himself until All For One was the only one to offer him any sense of security, no matter how toxic. Shigaraki cares only for his friends and allies in the League of Villains who are safe from his wrath, and he won't rest until the world understands his pain through total annihilation.
  • Rule of Symbolism: The narration itself nots that his Body Horror forms are reacting to his emotional state and intentions, effectively manifesting his desires in a twisted physical form.
    • The first is simply 'a bloated mass of fingers, forever seeking destruction', pushing the world around him away at arms length and being capable of infecting a magnified version of his 'Decay spread' through every single finger he grows, if Erasure wasn't already being used on him by the time he unleashed it. This represents Tomura's pure desire to destroy the world around him that utterly rejected him as a child, rejecting it and everyone in it in turn.
    • The second is a more concentrated, humanoid defensive form, with the fingers instead growing into facsimiles of armour and a mouthpiece, and his left arm growing into a massive bloated hand similar to All For One's mass quirk combination, with each 'finger' on the arm being a fleshy recreation of a member of his family or the old lady who walked away from the traumatised Tenko, capable of unleashing powerful blows on the level of All Might's, with similar paneling effects to drive the comparison home. This form was triggered in response to his anger over the heroes sparing no effort to revive Bakugou after he broke him, whereas Tenko received no such support, and symbolises Tomura both retreating into himself so as to no longer be hurt by others, whilst also using the source of him trauma as a weapon to strike back at others.
  • Sadist: Shigaraki visibly enjoys using his powers and is capable of some pretty disturbing acts of violence, just ask Overhaul. His grins doesn't help matters. After he upgrades himself with Garaki's biological remodelling, he clearly revels in the change to physically dominate the heroes and prove his strength by enduring everything he throw at him and returning it tenfold. Notably though, his attitude throughout is one of self-satisfaction in his abilities, and whilst he considers the heroes' efforts useless, he nonetheless appreciates the challenge they give him. This changes as his mental assimilation with All For One continues, as his master's spiteful attitude begins to influence him into becoming more cruel, mocking, and derisive of the heroes even trying to fight him, going out of his way to mock and break their bodies and wills just because he can.
  • Sanity Has Advantages: Initially, he is clearly dangerous to be around, with a childish personality, a tendency to get easily upset and throw tantrums when things don't fall his way, and his proud, petty nature meant that he wouldn't work with anyone who annoyed or disrespected him somehow. He mellows out considerably after All For One is incarcerated and he's forced to forge a new path for the League on his own, earning genuine loyalty from his underlings and being more adaptable on the fly.
  • Scars are Forever: While it might not be as easily noticeable, or at the very least something the audience can write of as being caused by his dry skin, Shigaraki has noticeable scars on his right eyelid and the left side of his lip. Chapter 236 reveals that the eye scar was a result of young Tenko clawing at his own eye after he accidentally killed his older sister while the lip scar came from his father smacking him with a weed whacker after witnessing his rampage.
  • Self-Harm: Shigaraki often scratches his neck and, as shown in Episode 11, if he starts having a psychotic episode, he'll scratch himself so hard that he starts drawing blood.
  • Self-Made Orphan: He accidentally killed his entire family when his Quirk first activated, leaving him in the miserable state in which All For One found him. As of Chapter 222 of the manga, it's revealed that he only remembers fragments of the event, but they're enough to make him sick to his stomach. As he fights Re-Destro, the memories start coming back full force when his family's hands get damaged.
  • Shadow Archetype:
    • To Izuku Midoriya see Foil and Evil Counterpart above.
    • He is also this to Eri. Both of them manifested Quirks which none of their family members possessed. Upon manifesting the Quirks, they accidentally killed a family member and they have dissolved their fathers, albeit with a few differences. Afterwards, both of them were abandoned and were at the mercy of villains. However, Eri was discovered and saved by heroes while Tomura was rescued by All For One.
  • Shout-Out:
    • A multitude to Tetsuo Shima, the main antagonist of the acclaimed manga series AKIRA. Shigaraki sports a trademark, tattered red cape similar to Tetsuo's after emerging from his pod, fights off American soldiers in fighter jets in a sequence nearly ripped straight out of the series, has to wear a prosthesis on his left hand similar to Tetsuo's full one for his right arm, and can transform into a giant Blob Monster when his powers grow too much for him to handle. Lastly, both of their hair grow increasingly white as they become stronger.
    • To Anakin Skywalker/Darth Vader. He is an apprentice to a master he wishes to eventually usurp who deliberately fosters his anger and rage through physical and psychological abuse. Furthermore, like Vader, he has a shred of goodness remaining inside him in the form of the remnants of his Tenko persona crying out for help. Once Midoriya senses this, his new mission becomes somehow saving Tenko, mirroring Luke Skywalker's quest to save Anakin. This likely won't mean redemption, but there is a chance the part of his soul that's still Tenko can be spared to some degree. He even acquires a new "mask" of sorts when the one remaining hand he owns is charred black by Endeavor's flames, another similarity to Vader. Bonus points for being Nana's hand.
  • Slasher Smile: He sports one the first time we see his face. And that's not even going into the incredibly unsettling one he gives poor Midoriya later on in their conversation. Chapter 223 makes note that Shigaraki has been smiling like this for over a month despite (or maybe because of) being in terrible danger. As a child, his smile was part of the reason why no one came to help him, he was that scary.
  • Smart People Play Chess: Amusingly averted. Shigaraki has no idea how to play chess. He's really bothered when Overhaul forces him to play a few rounds of shogi during their meeting. When the time comes to use chess metaphors, all Shigaraki has figured out is "you win by taking the other guy's king".
  • Smarter Than You Look: Thanks in no small part to his initial childishness and psychotic episodes, it can be difficult to remember at times that Shigaraki is actually an incredibly smart villain. This can be seen during his fight with Aizawa when he was able to determine that the duration of time the latter could erase Quirks was getting shorter and when he came up with the plan to successfully capture Bakugo. In fact, according to his stats in the Official Character Book, he ranks 5/5 or A in intelligence, which for the record makes him smarter than Midoriya and Kurogiri, who both scored a 4/5 or B.
  • Smash the Symbol: After recovering his memories during his fight with Re-Destro Shigaraki destroys his father's hand declaring it unnecessary. His family's hands were meant to keep his old memories as Tenko Shimura locked away while aggravating his aggressive tendencies to help him embrace his need for destruction. By deliberately destroying his hands, Shigaraki has truly left his past behind him and now fully embraced his role as a vehicle of destruction.
  • Smug Super: Delighted and bloodthirsty about the new strength Dr. Garaki's experiments and transplanting the original All For One Quirk grant him. Taken down a peg when All For One performs Grand Theft Me on him, but there's enough of his cockiness left throughout the last few arcs for him to still be very happy with the new powers he wields even if he's forced to share. And of course, he becomes fully happy once again once he stops All For One's Fusion Dance with him and gets full, complete ownership of the Quirk.
  • Soul Jar: All For One's ultimate plan for him, in a sense, as he tries to merge their Quirk vestiges into one supreme being. It's a work-in-progress.
  • Split Personality: Once the All For One/Tomura fusion begins to break down, the Tenko part of Tomura resisting All For One is revealed to have caused Tomura to develop a split personality: Tomura still wants to be Deku's villain and continue his plans while Tenko wants to be saved.
  • Split-Personality Merge: A very rare non-consensual example. The nature of All For One's plan involves merging himself and Shigaraki into a singular, supreme being at the cost of their own individuality, and Shigaraki himself undergoes an identity crisis where he doesn't understand whether he's still Shigaraki, becoming All For One, or even his old personality as Tenko Shimura. Becomes an instance of Fridge Brilliance when you realize the word for Quirks in Japanese literally means individuality, making Shigaraki grapple with who he truly is as he seeks greater power. The events of the final battle cause the two to begin to break apart.
  • Spoiled Brat: Before his character development, Shigaraki would complain and lash out when things didn't go his way; even Dr. Garaki mentions that Kurogiri had coddled and spoiled Shigaraki too much.
  • The Starscream: During the Paranormal Liberation War Arc, he becomes one to All For One after he finds out All For One is trying to take control over his body. They proceed to fight over their shared body all the way to the series' final battle.
  • Straw Nihilist: He has nothing but absolute contempt for the society that heroes have created, seeing it as nothing but a big lie that people have deluded themselves into believing for a false sense of security, and fostering a culture of Bystander Syndrome and Holding Out for a Hero mentality. So, he resolves to tear it all down, forcing everyone to confront the grim reality they have so blithely rejected.
  • Stupid Evil: Very much so early on. Shigaraki's temper caused him to make incredibly short-shorted decisions that backfired horribly and would have ended his villain career if not for Kurogiri and All For One. After his talk with Midoriya, he begins to grow out of this.
  • Super-Persistent Predator: Imagine if your greatest enemy became a nigh Physical God and made it their mission to hunt you down. This is what happens between Shigaraki and Midoriya during the Paranormal Liberation War, and he only grows more determined to steal One For All from there with All For One's consciousness merging with his own. Even when he breaks off the hunt after verifying that Tomura's body and mind-state aren't yet at the proper level to subsume One For All for good, and being forced to complete his 'evolution' in the meantime, All For One's original body spends this time using his resources, connections, pawns and vast experience manipulating people to relentlessly press Izuku and steadily grind him down whilst Tomura prepares for the rematch, exploiting Izuku's desperation to finish their fight whilst his Arch-Enemy is weakened to fruitlessly tire himself out and making Izuku very aware that he's right to be so desperate and scared of what's coming for him. He only has Tomura's body step forward to deal with Star and Stripe trying to aid the heroes, and even then it's made clear a major part of his motive is denying Izuku the aid of someone powerful enough to actually protect him from Tomura's hunt for him.
  • Superpower Lottery:
    • His Decay Quirk, put simply, gives him the power to destroy things, with no real limit to what he can break. The only two limitations are that he needs to touch a solid surface (As demonstrated in his fight with the Sand Hero Snatch) and that he needs all five fingers to make contact with the victim. The Meta Liberation Army Arc reveals that, due to Shigaraki subconsciously repressing the memories of killing his family, his Quirk is being suppressed. Once he "liberates" those memories, he shows off some truly destructive feats such as disintegrating an entire group of people by spreading the decay like a virus, bringing down a skyscraper with a single touch, and later obliterating an entire city.
    • In the Paranormal Liberation War Arc, after awakening from an intense medical procedure, Shigaraki not only gains full control of his Decay Quirk, but also gains the original All For One Quirk and all of the numerous Quirks All For One stole with it. Also, the procedure modified his body to grant him immense strength even without a Quirk.
    • During the commencement of the Final Battle, Tomura reveals a new ability of his, by forcibly 'evolving' himself into 'the next stage of humanity', his body becomes capable of adapting itself to suit the situation, seeking a form that is best capable of holding the immense powers contained within One For All's Quirk to avoid his vessel breaking from the strain. This manifests as him being able to grow massive mounds of cancerous-looking flesh as big as a building with no apparent limitation for how much he can 'grow'. This ability is also not a Quirk, despite how it looks, so Erasure cannot prevent him creating massive Combat Tentacles to fight the heroes with, meaning even after they prepared a custom-made battleground to contain and defeat him, Tomura still holds the advantage against the heroes.
  • Super Speed: While it has yet to be commented on In-Universe, Shigaraki is very fast. This is best demonstrated in the USJ Arc, wherein once he notices Midoriya, Tsuyu, and Mineta, he suddenly goes from being in the middle of the training grounds, to right in front of Midoriya and company, in the blink of an eye. Shigaraki has 5/5 or A in speed. He is officially recognized by Midoriya to be incredibly fast after Dr. Garaki further enhances his physical abilities, now able to Flash Step faster than both an improved Bakugo and Midoriya at 30% could react to, forcing Midoriya to use more of One For All to keep up with him. He also appears to have developed Super Reflexes to compliment his new speed as well.
  • Super Strength: Chapter 276 reveals that the procedure that transferred the All For One Quirk to him also modified his body to grant him immense strength even without a Quirk, allowing him to leap high into the air and move with intense speed. He was also strong enough to send both Endeavor and Ryuku crashing to the ground with a single punch. This is taken a step further in chapter 366 when the stress and panic of having his Quirk's erased and being pushed back by the heroes causes his body to create a new ideal form for defense, causing the multitude of arms and fingers he created to wrap around his body to form a protective shell and buff up his left arm. His new form is able to deliver attacks with the same power as All Might as demonstrated with the sound effects using the same Smash! word blooks as when All Might used his attacks.
  • Superior Successor: An invoked and somewhat subverted example until ultimately being played straight. All For One never had any intention of bequeathing his power simply to retire or die off. He's groomed Shigaraki, a fact Shigaraki himself calls him out on, with the express purpose of merging their Quirk vestiges so they become the same person. This means he's been cultivating a superior version of himself rather than raising a proper heir to his legacy. But the real kicker is that he does such a good job stoking Shigaraki's rage that his adopted son becomes more suited to using the All For One Quirk and derails All For One's plan to use him to steal One For All, declaring he has no need for it. Shigaraki proceeds to blow up All For One's vestige and asserts true control of the Quirk, proving himself better than his master in every way.
  • That Man Is Dead: Combined with his multiple alias throughout the story, Tomura's fracturing mental state towards the end resulting from his Split-Personality Merge results in him losing sight of his own identity and true name as both halves of his Mind Hive merge together into a new existence, something that is neither truly Tomura, not All For One. This winds up protecting him from Star and Stripe's Quirk effect, exactly as All For one was counting on, and afterwards, the resulting personality seems to have become mostly All For One's with traits of Tomura's cocky attitude and sarcasm sprinkled throughout his mannerisms. Indeed, the only part of Tomura that was able to hold onto its individuality was his suppressed better qualities as 'Tenko Shimura', meaning that 'Tomura' has effectively been 'killed', and the TomurAFO personality resulting from the merger considers itself separate from both Tomura and All For One by the present point.
  • Then Let Me Be Evil: His father abused him as a child for wanting to be a hero like everybody else. So he kills him (purposefully) and the rest of his family (accidentally) who were bystanders. Furthermore, absolutely nobody bothered to help him in the aftermath and left him to starve. All For One then steps in to foster his hatred and things only grow worse from there.
  • To the Pain: In one of his most sadistic and vengeful moments, Shigaraki inflicted this punishment on Overhaul. He decides to avoid killing the man outright, in favor of something worse. He has Mr. Compress destroy Overhaul's left arm as payback for taking his, and personally decays and severs Overhaul's right arm with a knife. This leaves Overhaul crippled and incapable of activating his Quirk ever again. He then steals the materials to make Quirk neutralizer bullets. Finally, Shigaraki laughs in Overhaul's face and tells him that now he's powerless, he'll be forced to watch in envy as the League of Villains becomes the dominant power.
  • Too Many Mouths: Can sprout extra mouths on his grotesque assemblage of evolved extra limbs and fingers as a natural response to an attack like Tamaki's Scorpius Toxin.
  • Took a Level in Badass: After All For One is captured, Shigaraki improves considerably as a schemer and fighter, playing the heroes to his advantage to take down the Shie Hassaikai when they start posing a problem. He was already quite strong to begin with, but was limited by the need to touch his foe. The full power of his Quirk is shown during the Meta Liberation Army Arc, where he learns how to project and spread his Decay at a distance, giving him a tool to defend himself from attacks by decaying them before they touch him, and enough destructive power to level a city. During the Paranormal Liberation War Arc, after awakening from a procedure designed to transfer the original All For One Quirk to him, Shigaraki gains full control over his Decay Quirk, allowing him to choose what he wants to destroy as he was able to kill X-Less while keeping his cape intact, stop his Quirk from destroying the facility he was housed in, and hold his phone with all five of his fingers without destroying it. He also now has access to all of the Quirks his master had stored for him giving him a vast stockpile of powers. And if all that wasn't enough, Tomura's 'evolution' grants him the Adaptive Ability to control his body's 'growth' to sprout building-sized masses of cancerous flesh to attack the heroes with, something that apparently counts as a natural biological state and cannot be shut off with Erasure. By present, it's made clear that Tomura will do whatever he has to to become an unstoppable force in battle to sweep away all opposition to his dream of destorying society. All For One's aim is to enable him to put in the hard work towards achieving this, then become Tomura in order to become his desired 'Perfect Demon Lord'.
  • Took a Level in Kindness: With the arrest of All For One and his subsequent Character Development, Shigaraki gradually shifts into this; developing a better rapport with his compatriots over time, to the point that he declares in the Meta Liberation Army Arc that he has no need for a future of his own and just wants his League to live how they see fit. This proves to be outside All For One's calculations, as whilst he always intended Tomura to undergo Character Development to improve himself as a villain, he believed that Tomura would only improve his vindictive and hateful nature, and was completely blind to the possibility of his protege developing more positive qualities from interacting with the league, even if he still turned those qualities towards evil. As a result, when All For One enacts a Split-Personality Merge between them, he's unable to absorb all of Tomura, as part of his better nature remains separate from his more negative traits, enabling Tomura t still resist.
  • Touch of Death: He can disintegrate anything his hand connects to, but only when all five fingers are touching it. The Quirk does not spread if an appendage being decayed is severed, something which Shigaraki is aware of and may use for his particularly evil punishments. He later gains the ability to spread his decaying power like a virus so that it's able to affect other people and objects that he hasn't touched, as long as they come in contact with something or someone that has already started decaying. As if that wasn't enough, he later forces his body's 'evolution' into 'the next stage of humanity' to withstand the sheer overwhelming power he's gained from All For One's Quirk, becoming capable of mutating his body to sprout massive fleshy growths of hands and fingers as large as a Kaiju. The heroes are horrified to realise that if Aizawa's Erasure is turned off and Tomura becomes capable of using Decay through all his hands, they'll all die in seconds, along with everything in the surrounding area.
  • Tragic Villain: Tenko Shimura was an innocent child who dreamed of becoming a hero. His father, however, hated heroes and kept abusing Tenko for claiming he wanted to be one while his family did nothing to stop it. When his Quirk suddenly manifested he ended up killing his entire family, scarring his mind permanently as he sought help out in the city. But his pleas were ignored by the people around him, too scared by his ghoulish appearance, who thought that some hero would help instead. Being well and truly abandoned, Tenko would then be found by the supervillain All For One, who began to groom him into his weapon to capture One For All over the next 15 years. This is symbolised by his remaining good qualities inside his mindscape taking on the appearance of 'Tenko' pre-Quirk awakening, still crying in his back garden and waiting for somebody to help him, whilst his more negative side is represented by his present-day look of 'Tomura'.
  • Transplant: He's heavily based on the eponymous protagonist of Horikoshi's debut manga Tenko. Not only do they share the same name, but both share the same power, both are orphans, both have accidentally used their power on a loved one, and both are also driven by a deep hate for the world and a very intense goal to destroy something in it.note  During his battle with Star and Stripe Shigaraki's hair grows down to his waist making him look like an older version of Tenko. Tenko is effectively Shigaraki's prototype.
  • Trauma-Induced Amnesia: Whatever happened to Shigaraki in the past was apparently so traumatic that he can't remember anything more than brief flashes from before he met All For One. It's only after one of the hands that belonged to his sister gets destroyed by Re-Destro that his memories start coming back in force.
  • Traumatic Superpower Awakening: His Quirk became active while he was hugging his dog for comfort after a massive chewing out (for something comparatively minor) from his father. He then proceeded to accidentally kill his mother, sister, and maternal grandparents, before intentionally using the power to kill his abusive father. The experience was traumatic enough that when All For One and Dr. Garaki explained what happened that day, the shock and stress caused the poor boy to Go Mad from the Revelation and vomit.
  • Two-Faced: During the Final Battle, Bakugou's Howitzer Impact:Cluster attack successfully tears straight through the Kaiju-sized fleshy growths he's using to protect his main body and devastate the surroundings with, leaving a sizeable burn on the upper right side of his face and eye, possibly blinding him in it. Thanks to the effects of Erasure blocking his Healing Factor, he's stuck with the injury afterwards for several chapters. This is notable, as by that point Tomura's enhancements had advanced to the point that his skin could barely be scratched by the heroes' best efforts, showing how powerful the attack was to leave such a visible injury.
  • Unskilled, but Strong: After gaining All For One, he's able to use the raw power of it, combined with the regeneration powers and extra strength of his augmentations to handle it, in order to fight off several strong heroes at once. However, similar to Midoriya's experience with One For All, he's still a novice with using all the nifty powers it gives him, and his augmentation process was only 75% complete when his capsule was broken open. As a result, when he's pushed too far from accumulated damage, his body suddenly tears open when his regeneration is taxed out, and while he heals over it takes several precious seconds. In fact, this was intentionally enforced by All For One himself, as he picked and chose Quirks that would be incredibly easy to use and strong in power, so that even though Shigaraki would start out as an amateur with the Quirk, he wouldn't need to think or experiment too much in order to use it properly.
  • Unstoppable Rage: He murders his father in a rage when his Quirk manifested. Even more unsettling, All For One keeps him in a constant state of agitation to slowly groom him into an avatar of indiscriminate carnage. It's established many times that Shigaraki is filled with endless rage, all for the sake of accruing the grit required to steal One For All. Too bad for All For One that Shigaraki ends up so unstoppable he eradicates his vestige instead and takes over the position of Big Bad for good, uninterested in stealing One For All and instead choosing to destroy it and hero society outright.
  • Unwitting Pawn: Justified example for All For One. Owing to their relationship and the fact All For One sold his actions as being for Shigaraki's sake, Shigaraki overestimates the agency he has as All For One's successor, and is caught off guard when the latter hijacks and takes control of his body in the Paranormal Liberation War Arc. This is later discussed at the Tartarus jailbreak: when Shigaraki calls AFO out for treating him as a "chess piece," All For One does not deny doing so, but claims that Shigaraki is his "future king" and not a pawn. Since All For One's aim to become the 'Perfect Demon lord' he dreamed about as a child, he was quite serious about putting every resource and effort he had at Tomura's disposal to enable him to be a better and stronger villain than him, and was willing to 'sacrifice' his old and broken body for his sake, but deliberately mislead his protege about his intended aim for them both.
  • Used to Be a Sweet Kid: Tenko came from a (mostly) loving family growing up and genuinely aspired to be a hero, not unlike Midoriya. In fact, he was willing to include other boys who had no one to play with in his friend/ playmate group. But the repeated abuse from his father, the rest of his family's refusal to stop it, and his Quirk awaking at the worst possible time and in the most tragically violent way possible utterly broke him.
  • Vague Age: Shigaraki's age was initially speculated to be anywhere between Midoriya's age and his mid 20s due to his appearance, Nightmare Face, personality, and height. His age is not revealed until 200 chapters after his debut, finally confirming that he is 20 years old.
  • Villain Has a Point: Shigaraki begins as little more than a Psychopathic Manchild who's simply been handed resources he should never have been given access to. But as he matures and his Woobie, Destroyer of Worlds background is shown, it's made evident he does have clear reasoning behind his agenda. He's undoubtedly a monster for all the atrocities he puts into motion, but society's systemic issues played just as much of a role in his rise to power as his own agency did.
    • In chapter 363, after Bakugo's tragic death as a result of his Heroic Sacrifice to try and stop Shigaraki from destroying and killing all of the heroes of Japan, the heroes lament in anguish about failing to protect the young hero. Shigaraki then points out, despite he himself holding no qualms about harming children, that the heroes have placed the heavy burden on saving hero society on the shoulders of the young heroes-in-training, that they were the ones who forced them to participate on the front lines of the war. So this they should expect that they run the risk of some of them losing their lives. The heroes silently concede to this point and attempt to revive Bakugo.
  • Villain Protagonist: In the Meta Liberation Army Arc, Shigaraki serves as the main protagonist being front and center of the arcs major conflicts, with his past and struggles to truly succeed All For One being the highlight. This highlights his role as Midoriya's Arch-Enemy, capable of undergoing his own journey in parallel to his destined enemy's. From this point on he has such consistent character development and focus in the story there's an argument he emerges as the series' true Deuteragonist.
  • Villain Respect: Unusually for him, Shigaraki doesn't get angry when a bruised and battered Aizawa stops him from using his powers on Tsuyu, and instead compliments the hero. The sentiment remains even when Shigaraki shoots him with a deleter round but Aizawa cuts his affected limb off and manages to stare the villain down:
    Shigaraki: You really are so cool, Eraser Head.
    • He retracts his respect during the battle at U.A., saying Aizawa "turned out to be quite the letdown..." Perhaps as an indication his hatred for society has begun eroding what sympathetic qualities he had with All For One slowly consuming his consciousness.
  • Villainous Breakdown:
    • He had a habit of flipping his shit when things didn't go his way early in the story, though he largely grows out of this as the story goes on. It still happens on occasion, like when Re-Destro first starts destroying Shigaraki's hands, he has a mental breakdown as the memories of his past come crashing down on him, but he begins to calm down when only his father's hand is left. When his flashback is over, he decays the final hand with a smile on his face, seemingly fully recovered from the breakdown.
    • Seeing the heroes work so hard to revive Bakugo after he already killed him sends Shigaraki into a childish, murderous rage, furious that they would try so hard to fix what he'd already "destroyed" when he was offered no help as a kid. His rapidly evolving body changes into a new defensive form when combined with the hits he'd taken during the battle, showing he's come to reject everything and retreat into himself to avoid being hurt anymore, physically and emotionally.
  • Villainous Friendship: While Shigaraki tends to be a mostly antisocial asshole, he does seem to legitimately care for Sensei. He reacts in fear when he realizes that Sensei is going to be fighting All Might by himself while still recovering from his injuries. As the story progresses, he also starts developing a closer relationship with the rest of his core team, as a sign that he's growing into the role of a leader after All For One is arrested. Of course, he comes to hate All For One too in time once he commits Grand Theft Me on him, and he turns into a very different person from the one the League know and have bonds with.
  • Villainous Underdog: Frequently, especially after All For One is defeated and Shigaraki has to assume leadership of the League of Villains himself. This gets averted after he assumes control over the Meta Liberation Army and has Garaki upgrade him to become almost unstoppably powerful in a fight.
  • Visual Development:
    • After his character development, he starts wearing a long coat and his face is no longer drawn in a nightmarish style. By the time he meets Gigantomachia and Dr. Garaki, his hair has also gotten longer and more unruly.
    • Another example of his character development is the presence of the hand covering his face. When first introduced, Shigaraki wore it at all times and the audience never got a chance to see his face aside from brief glances. He also showed a lot of panic whenever it was damaged or separated from him. His ambush of Midoriya in the mall, where he starts to form his own convictions, is the first time the audience is treated to his unobscured face, and from then his independence from the hand begins to grow, as he controls his panic when it is forcibly removed, and even willingly takes it off to earnestly speak with Toga and Twice. By the time of the Meta Liberation Army Arc, Shigaraki spends most of the battle without "father" on showing how confident he is as a leader, culminating in him finally destroying the hand, since he no longer needs it.
  • Voice of the Legion: After having received the All For One Quirk and when All For One's vestige takes control of him, he speaks in a menacing blend of the two voices in the anime.
  • White Hair, Black Heart: Downplayed; he's less Bishōnen than the standard, and his hair is a pale gray-blue rather than pure white, at least until his power up in Volume 25 where it actually does turn white. Otherwise, he plays this straight, especially given his red eyes. It goes further after his Split-Personality Merge with All For One's vestige, as his master's cruel sadism gets expressed very frequently in the way he fights and belittles his opponent's efforts, even down to mocking Bakugou with the reality that he will never be capable of becoming the number one hero in a world where he has to compete against the ridiculous powers of One For All and All For One, just because he could. At the same time, the merger separates Tomura's more negative qualities from his good ones, meaning that his eviler traits are now more expressed as part of All For One, and all that remains of Tomrua that can still call itself 'Tomura' is his childhood self.
  • Why Don't You Just Shoot Him?: Prior to his Character Development regarding his own motives, he manages to infiltrate a mall and get his hands on Midoriya's throat. While he could seize the opportunity to kill the current holder of One For All and snuff out the biggest threat to his master forever, he instead converses with Midoriya regarding his frustrations with Stain. It's later revealed that he was completely ignorant about One For All or his master's obsession with it, and thus had no idea he technically had an opportunity to kill the biggest obstacle to his dream of destroying society, seeing Midoriya as just another All Might fanboy amongst thousands. However, when he's later made aware of the importance of One For All, by that time the vestige of All For One has started taking mental control over him, and adamantly refuses to allow him to do anything that will destroy the Quirk before it can be absorbed. When the heroes assemble against the villains in a massive ambush, Tomura can be seen struggling to put his hand on the ground and unleash his Decay wave against them to wipe them out in a single move, only for it to refuse to move because Izuku is also in the line of fire.
  • Woobie, Destroyer of Worlds: He was regularly abused by his father, Kotaro Shimura, for wanting to be a hero while the rest of his family stood by and watched. Until one day he developed his Quirk and lost control of it, accidentally killing most of his family in what was implied to have been a subconscious rage before finally snapping and killing his father. Afterwards, he wandered the streets while everyone around him was too creeped out by his appearance to help until All For One found him. From there, he was groomed into becoming an unhinged mass murderer. It's such a tragic upbringing that Izuku, his own Arch-Enemy, realizes he never deserved it and begins searching for some way to save him.
  • World's Strongest Man: Even in his incomplete state, Shigaraki, who possesses the original All For One Quirk and a bioengineered body with abnormal physical prowess, counts as this. He can easily destroy entire cities with a mere touch and even the top 10 pro heroes are no match for him. In practice, however, he is a meat puppet to All For One, who is attempting to claim Shigaraki's new power for himself in his bid to become an invincible Demon Lord. Ultimately, Shigaraki is so strong that it took America's own No. 1 hero, armed with a Quirk that alters the very rules of reality in her favor, pulling a Heroic Sacrifice to damage his Quirk factor from the inside out. This permanently destroys an untold number of his accumulated abilities, giving the heroes a viable chance of beating him. The only one who could possibly take the title from him even after all that is Izuku, who's starting to master the full variety of powers One For All grants him. Not to mention they are destined to fight for it.
  • Would Harm a Senior: To him, it doesn't matter how old someone is if they rub him the wrong way. This is displayed most gruesomely when he maims Gran Torino.
  • Would Hurt a Child: When he runs into Midoriya at a shopping mall, he admits he could kill at least twenty people before he'd be stopped, and the visuals accompanying it make it clear this means everyone is free game, including children.
  • Xanatos Speed Chess: Takes after his master by doing this and actually executes it even better. Realizing All For One would never willingly give him control of his body back, Shigaraki allowed himself to be suppressed while keeping a portion of his psyche behind to progressively regain control of his body. By holding onto his "origin", Shigaraki mustered the willpower to override All For One's hijacking and destroys his vestige, rejecting All For One's goal of stealing back One For All and doubling down on his own dream of destroying hero society.
