The Dimorphic Hero

Name: Izuku Midoriya

Quirk: Sexually Dimorphic

Description: Izuku has 2 bodies that exist simultaneously, one male body, and one female body. The male body is hyper-masculine, and the female body is hyper-feminine. The male body is less flexible and maneuverable, but far stronger and faster, possessing a peak-human musculature. The female body is weaker and slower, but possesses peak-human flexibility and is far more maneuverable. Despite possessing 2 bodies, Izuku only has a single mind controlling them both, and both bodies share senses, including pain. If one body dies and the other survives, the dead body will be replaced 24 hours later, quite literally growing out of the surviving body. Both bodies are vastly superhuman in different ways.
