Re: Trinity War??
The only thing is that they stripped Volthoom down to his core and left him powerless before they vanished him. So I don't know how he'd be able to conjure up a new power ring to give away if it was indeed Earth 3 he ended up in. But it's possible that an alternate universe Volthoom is the one behind Power Ring's power.
I enjoy comic book adaptations but I'm a comic book fan first and foremost. Not a comic book movie fan.
