MHA — League of Villains

Dabi (real name Touya Todoroki) is a tall, slightly thin, and strong guy.

He is a villain and member of the League of Villains. He is the "deceased" son of the hero Prospector. His Quirk is "Blue Flame"—his hands emit a stream of blue flame. Long-term use of this Quirk can cause his skin to smoke, creating a charred smell in the air.
Dabi has scars covering most of his skin, covered with staples. This sometimes makes it seem like he's always smiling.
He used to have red hair, but then it turned white because of his quirk, and then Dabi dyed it black so that no one would recognize him.

Tomura Shigaraki (real name Tenko Shimura) is a well... 22-year-old man/guy with a thin and fairly tall build.

He's almost the leader of the League, you could say. He has light blue hair, dry, calloused skin, and red eyes.
Quirk - "Decay" - everything he touches with five fingers settles and turns into dust.

All Might (real name: Toshinori Yagi) is the symbol of peace (the number one hero). His Quirk, "One For All," can enhance any limb, strength, and speed, and is also useful for defense. He is Izuku Midoriya's mentor.

Endeavor (real name: Enji Todoroki) is the number two hero. His Quirk is "Hellfire"—his hands can release a stream of powerful flames. He wants to surpass All Might (become his superior) and has children—Fuyumi, Natsuo, Shoto, and Touya (a villain from the League of Villains who was "deceased").

Hawk (real name Keigo Takami) is the number three hero. His Quirk is "Red Wings" – he has large red wings on his back, which he uses to fly and control each feather.

Best Jeanist (real name Tsunagu Hakamata) is the number four hero. His Quirk is "Fiber Master," which allows him to manipulate fabric (every single thread), primarily denim. He runs his own agency, "Genius Office," and was Bakugo Katsuki's mentor.

Edgeshot (real name Shinya Kamihara) is the number five ninja hero. His Quirk is "Foldabody," which allows him to fold his body into any shape, even the smallest.

Midnight (real name Nemuri Kayama) is the 42nd hero (her Quirk is "Sleepy Scent" - she can emit a soporific scent from her body). She teaches at U.A.

Present Mic (real name Hizashi Yamada) is the 43rd hero. His Quirk, "Voice," allows him to amplify the volume and frequency of his voice to the point of deafening (or worse). He teaches English at UA.

Eraserhead (real name: Shota Aizawa) is the 44th hero. His Quirk is "Erase" – he can erase his Quirk with a glance, but blinking or looking away will cancel the effect. While the Quirk is active, his hair rises and his eyes glow red. He is the homeroom teacher of Class 1-A at U.A. and a friend of Midnight and Present Mika.
