A question if you would....

Simple, Would Aizen make an excellent villain without all the plot armor and god mod? I'd say yes, simply because his genius in tactical ability would not be matched.

I say Gin would be better because he just seems more villain like.

Gin FTW

Hell yes. Lets face it, Gin was influenced by Aizen and Gin follows Aizen. Without the God mode whatever the hypothetical situation, Gin wouldn't have rebelled against Seireitei. Plus almsot ALL villians are god modded in Manga, Like it or not -_-. So I would say without his powers Aizen still makes a good villian because of how well he manipulates and Baits the anger in people with a sentence and a smile.

Gin doesn't seem superior anymore, Hes more like a lame character. Even Kon seems much stronger them him right about now.

Gin's Bankai is pure epic. Fastest Zanpaktuo. 13KM

Go suck a chode Blade.

Aizen would still be a great villain even without the godmode because he's a stragtegist and a manipulator
