The Fly is a man with long light blond hair that reaches to his feet, with long bangs that cover the left side of his face. Two long wing-like appendages emerge from his arms. His hero costume consists of a short-sleeved shirt and white shorts, two large armbands on his biceps, and a thin red headband, as well as dark coloured boots.
Not much is known about his personality at this time.
The Fly was in Hosu City when the Nomus released by Tomura Shigaraki attack the city. The Fly and other heroes face them but the Nomus are too strong for them despite their numerical superiority. They manage to hold them long enough until Endeavor arrives and defeats the creatures.
