Kurogiri/Synopsis

History
After the death of Oboro Shirakumo, his body was recovered by All For One and taken to Daruma Ujiko, who combined various quirks to create the Nomu called Kurogiri. All For One tasked Kurogiri with aiding and overseeing the development of Tomura Shigaraki.

U.S.J. Arc
Kurogiri appears at the Unforeseen Simulation Joint, using his Quirk to warp himself and the villains to the area. He then appears before the escaping class of students, introducing themselves as the League of Villains and revealing that they were the ones who broke into U.A. High School the previous day.

He goes on to say that their mission is to kill All Might and wonders why he isn't here. Katsuki Bakugo and Eijiro Kirishima attack Kurogiri, but their attacks simply go through him. He then uses his Quirk to warp most of the students to various areas of the USJ.

After doing this, Kurogiri fights Thirteen. Kurogiri uses his Quirk against Thirteen's Quirk by warping Thirteen's Black Hole against her. As Thirteen's Quirk starts turning her to dust, Kurogiri says that Thirteen's battle experience is far lower than other heroes due to her only specializing in disaster relief. Having incapacitated Thirteen, Kurogiri tries to stop Tenya Ida from escaping, knowing that Tenya's escape would put the League of Villains in jeopardy, but is intercepted by Mezo Shoji.

As Tenya reaches the exit, Kurogiri tries to attack him again, but Ochaco Uraraka, seeing a physical part of him, is able to grab him and use her Zero Gravity to make him float into the air, stopping him with the help of Hanta Sero and Rikido Sato. After being flung into the air, Kurogiri decides to warn Tomura and warps himself away. He appears before Tomura Shigaraki, and informs him on the situation, telling him that he has incapacitated Thirteen but failed to stop one of the students from escaping, much to Tomura's frustration. Realizing that the escaped student will most likely go and find dozens of Pro Heroes whom they won't be able to defeat, Tomura decides to retreat, but not before killing the remaining students.

Shigaraki and the Nomu attack Izuku, Tsuyu, and Mineta, but before they have a chance to hurt them, All Might arrives at the scene. Tomura decides to continue his mission. All Might starts by striking Nomu, but the creature absorbs the impact. All Might figures that he can wear Nomu down, and uses a powerful reverse suplex to smash Nomu into the ground. However, Kurogiri intervenes, using his Quirk to save Nomu and allowing Nomu to turn the tables on All Might. All Might sends half of Nomu's body through a portal while he still remains in the suplex position. Nomu uses the opening to grab onto All Might's weak point, while Kurogiri slowly drags him into the warp gate, to carry out his duty to eviscerate All Might.

Alert to All Might's peril, Izuku rushes over to aid him. Kurogiri cuts Izuku off and prepares to warp him away, but Katsuki appears and strikes Kurogiri and pins him down, preventing him from using his Quirk. Kurogiri is then set free when Nomu attempts to attack Katsuki. Knowing that his powers are declining rapidly, All Might engages Nomu in a ferocious fistfight. All Might decides to surpass his 100% after seeing that his attacks are having minimal effect. All Might launches a devastating punch against Nomu, sending Nomu flying out of the U.S.J., defeating him.

After All Might defeats Nomu and Tomura starts to panic, Kurogiri calms him down by saying that Nomu did considerable damage to All Might and they should take the opportunity to finish the job. After Tomura regains his composure, he and Kurogiri attempt to attack All Might, but they are intercepted by Izuku Midoriya, which gives the heroes enough time to arrive at the USJ, in turn forcing Tomura and Kurogiri to stop their attack. They are then sucked into Thirteen's Black Hole and are seemingly turned into dust, but Kurogiri uses his Quirk at the last second to warp him and Tomura back to their hideout, thus saving themselves from being killed. After the mysterious voice on the monitor asks about the whereabouts of Nomu, Kurogiri regretfully reports that they do not know Nomu's coordinates due to him being thrown far away and were unable to pinpoint his location, thus being unable to retrieve him.

U.A. Sports Festival Arc
Kurogiri appears before the hero killer, Stain, who draws his katana and aims it at Kurogiri.

Kurogiri then asks Stain for a moment of his time, teleporting them both away.

Vs. Hero Killer Arc
Kurogiri brings Stain to the League of Villains hideout to meet with Tomura. However, the meeting between Stain and Tomura goes awry. Kurogiri asks the mysterious voice on the monitor if it is all right to keep the meeting going, but the voice orders Kurogiri to allow them to continue, saying that Tomura's meeting with Stain (an experienced infamous villain) will stimulate Tomura's growth.

The meeting between Tomura and Stain turns into a fight. Kurogiri tries to intervene, but Stain injures him and prevents him from moving. After Stain and Tomura declare their common interest in destroying the current society, Stain restores Kurogiri's mobility and demands to be returned to Hosu.

After Stain leaves to finish his business, Tomura complains about Stain's constant preaching, to which Kurogiri replies that he shouldn't mock Stain for his preaching and states that Stain's villainous methods have produced great results, which intrigues Tomura. Tomura orders Kurogiri to release the Nomu. Kurogiri warps three Nomus to their location, and Tomura orders the Nomu to attack Hosu.

Kurogiri asks Tomura if he will join the assault on Hosu. Tomura replies that he won't because of his shoulder injury.

Tomura, using binoculars, watches Stain kill the winged Nomu and becomes annoyed that nothing is going his way. After the other two Nomu are restrained and arrested, Tomura disintegrates his binoculars out of anger. Tomura decides to leave and return to the League of Villains hideout.

Kurogiri questions if the Vanguard Action Squad means nothing to him, but Tomura rebuffs Kurogiri’s claim, saying that he respects the Vanguard Action Squad’s strength and personally hopes they succeed, Tomura continues to say that while they have their differences, they can rely on each other because both he and Kurogiri are not the only ones oppressed by society’s rules.
