Tsubasa (翼 Tsubasa?) was a friend of Katsuki Bakugo as a child, and 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: This Quirk gives Tsubasa a pair of wings that allow him to fly.
- Tsubasa means Wing in Japanese, in reference to his Quirk.
- In a Volume 7 omake, is implied that he was turned into the Winged Nomu, although it is not confrimed.
