"I'm a shapeshifter
At Poe's masquerade
Hiding both face and mind
All free for you to draw"
--Beneath the Mask, Lyn Inauzumi
I saw the theme masquerade and instantly thought of one of my old MHA OCs. This is Soraphimu Kenraku, and his quirk/power is to be able to take the form of whoever he makes prolonged eye contact with most feared person. Because of that, he usually wears a mask over his eyes.
