Personality
Black Mist is very polite, which is shown when he greets the students and introduces himself in a formal manner. However, like his fellow villains, he also showed a sinister side; threatening the students' by telling them that they would be tortured and killed when warping them to various areas of the U.S.J.

Ultimate Space & Jams Arc
Black Mist appears at the Ultimate Space and Jams, 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 Villain Alliance and says that they were the ones who broke into Yuuei yesterday. Black Mist goes on to say that their mission is to kill All Might and wonders why he isn't here. Katsuki and Eijirou attack Black Mist, but their attacks simply go through him. Black Mist then uses his Quirk to warp most of the students to various areas of the U.S.J.

After doing this, Black Mist fights No. 13. Black Mist uses his Quirk against No. 13's Quirk, warping No. 13's Black Hole against him, causing No. 13 to start turning himself to dust, prompting Black Mist to say that his battle experience is far lower than other Heroes due to him only specializing in disaster relief. Having incapacitated No. 13, Black Mist tries to stop Tenya from escaping, knowing that his escape would put them in jeopardy. Mezou attacks Black Mist, preventing him from attacking Tenya.

As Tenya reaches the exit, Black Mist tries to attack him again, but Ochako, seeing a physical part of him, grabs him and uses her Quirk to make him float into the air, stopping him. Black Mist decides to inform Shigaraki on the situation, telling him that he has incapacitated No. 13, but failed to stop one of the students from escaping.

Black Mist then uses his Quirk to protect Noumu against All Might's attack. As he is about to attack All Might, Katsuki strikes him and pins him down, preventing him from using his Quirk. Black Mist is then set free when Noumu attempts to attack Katsuki.

After All Might defeats Noumu and Shigaraki starts to panic, Black Mist calms him down by saying that Noumu did considerable damage to All Might and they should take the opportunity to finish the job. After Shigaraki regains his composure, he and Black Mist attempt to attack All Might, but they are intervened by Izuku, whose intervention gives the Heroes enough time to arrive at the U.S.J, forcing Shigaraki and Black Mist to stop their attack. Black Mist and Shigaraki are then sucked into No. 13's Black Hole and are seemingly turned into dust, but Black Mist uses his Quirk at the last second to warp him and Shigaraki back to their hideout, thus saving themselves from being killed. After the mysterious voice on the monitor asks about the whereabouts of Noumu, Black Mist regretfully informs that they do not know Noumu's coordinates due to him being thrown far away and were unable to pinpoint his location, thus they were unable to save him.

Sports Festival Arc
Black Mist appears before the Hero Killer, Stain. Stain draws his katana and aims it at Black Mist. Black Mist tells Stain to withhold his blade as they have similar interests and that he has been wanting to meet someone of his notoriety. Black Mist asks Stain for a moment of his time, teleporting Stain and himself away.

Field Training Arc
Black Mist brings Stain to the Villain Alliance hideout to meet with Tomura. However, the meeting between Stain and Tomura goes awry. Black Mist asks the mysterious voice on the monitor if it is all right to keep the meeting going. The voice on the monitor orders Black Mist to allow Stain and Tomura to continue their meeting, 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. Black Mist 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 Black Mist's mobility and demands to be returned to Hosu.

Black Mist teleports Stain back to Hosu as well as Tomura. After Stain leaves to finish his business, Tomura complains about Stain's constant talking, to which Black Mist tells Tomura that he shouldn't mock Stain's villainous methods as they have produced great results which intrigues Tomura. Tomura orders Black Mist to release the Noumus. Black Mist warps three Noumus to their location and Tomura orders the Noumus to attack Hosu.

Quirk
