Design of Infinite in my alternative universe - Two Nemesis AU(2NAU) where are Sin and Nemesis too.
He is from other dimension (once helped Nemesis to get back to her homeworld), stuck in Nemesis's body, but he can take control on her in some cases.
Also he can make "illusion body" for himself, but cannot use any Phantom Ruby abilities in such state.

Infinite himself belongs to Sega.
Art by me, of course.
