Tsubasa (翼 Tsubasa?) was a friend of Katsuki Bakugo as a child who helped him bully Izuku Midoriya for not having a Quirk. He is also the grandson of Dr. Tsubasa, the doctor who diagnosed a young Izuku as Quirkless.
In the flashback, Tsubasa is a plump child, with a rounded face and brown hair almost completely shaved. Due to his Quirk, from his back emerge two red and draconic wings.
As a child, he wore a tank top, green shorts, and sandals.
Unnamed Wing Quirk: Tsubasa's Quirk allows him to grow a pair of red, dragon-like wings from his back that allow him to fly.

- Tsubasa means "Wing" in Japanese, in reference to his Quirk.
- It's greatly implied that he was turned into the Winged Nomu, although it is not confirmed.
