Body Collector/Soul Eater

Deadied bab that lost his way to eternity and got stuck on Mobius after dying when half a city crumbled down, eventually decided that being just a lost soul sucks and started possessing bodies by eating souls that already existed within. It sorta became an addiction at this point tbh

At first he followed his twin sister Cleo around when he found her to somehow try and indicate he still exists, but at this point after having shuffled through a lot of bodies he lost his identity a bit and just follows her by habit, acting a bit like a messed up guardian angel. It's fitting considering she's a messed up child

They're both not entirely aware of each other, but at the same time they both have a weird intuitional feeling that the other twin is still around, even if they're not sure how it works.

He looks like a giant ethereal oil spill in a vague shape of a Mobian, due to how much of so many people he is now. He can literally barely contain himself, but it makes it easier for him to force himself into others bodies when he has the power of countless souls he's consumed
