there hasn't been any detail on what his abilities were. also, is he a reincarnated person...

i mean he's dead and he got revived so technically he's more of resurrected but the meaning is pretty similar to reincarnated so i guess you can say he is

Probably something along the lines of ability to directly use the big god's power or something... so kinda like whatever god can do he can do too (to some extend)
