Doesn't Batman, Superman, and Wonder Woman also know magic, so what? What you should be saying is how powerful they are with their magic compared to them.

Batman would probably be the first to die, and if rimuru can use gluttony on superman and copy his abilities it's kinda over since he'll be even stronger

I refuse DC Characters to loose, but I literally have no idea how powerful the other team is except being known for being the most powerful, well most and only Rimuru, Superman would destroy the others, it's only Rimuru who is a God-like figure.

Batman would have a hard time with any of them. Tanya the little blonde chick can make nukes with her prayer magic and has a lot of experience in aerial combat. Plus she’s really manipulative and an expert tactician. Think of her like a cute nazi girl that takes advantage of everything in her favor. The only person that has been able to stop her in her goal of living a care free life is a being that calls itself god. Batman’s plot armor can only do so much.

Ainz also has magic and items that can be described as divine

Isn't Tanya a dude?

She was but has seemingly excepted that fact and is maybe using it as fuel to get revenge on god

What do you mean by excepted? shouldn't he/she accept the fact instead? or is it another difference like he/she ignored that they changed genders to the point of not bringing it up at all?

The being that calls itself god reincarnated him as a cute helpless girl in a world that’s constantly at war because he didn’t have any faith in god and refuses to except the fact that god exists. His way of getting back at god is to climb the rankings to the top and enjoy a peaceful life. He hasn’t really excepted the fact he has changed genders. Might be because he is still a little girl (with the consciousness of an 40 year old man) and doesn’t possess a fully mature body. He doesn’t bring it up that much in the show so I can’t really tell.

U might have to watch it ur self because it’s been a couple years since I rewatched it and can’t remember the exact details.

IDK about the Web Novel and Light Novel, but in the Manga there was a Scene "Good thing I didn't bring my Rifle with me or else I would have blown my brains out" when she was thinking herself as a girl.

It doesn't bother her so much that she's a girl now what does bother her is when she thinks of herself as a girl instead of a Man.
