He kept his original body, but as his whole army is dead he can't do much so he just hides and occasionally steals humans for breakfast.

Transferred his conscious into the Doom's Eye, without main body he lost most of his powers so now he's just a creepy floatin starfish that lives in an abandoned house in the suburbs and eats people that come inside, creating creepypastas and shtuff

Something else *comment*
