I'm positive at least one person can help with this. I've started to notice something. Batman has incredible skills against mooks.

Whenever he does something really cool, like take someone down with nerve strikes, they always seem to be mooks. Or it's set in a different universe.

The best example due to being able to compare I can give is the Mutant Leader and Bane. Both of them defeated Batman the first time. However when Batman fought the Mutant Leader on the second time, he paralyzed his arm, and partially blinded him with his own blood, and gave him some broken bones.

Why doesn't he do that to Bane? Or any of his main rouges? Why does he just slug it out with them, and not use his fancy skills of nerve strikes and what not?

Bane's a trained fighter. He's lived since he was born in a hellhole of a prison. He knows how to fight, and he knows how to strategist. This usually carries over to most of his bad guys: They usually have a gimmick that prevents trying to be delicate with them (pressure points, etc). The Mutant Leader was a thug. A strong, vicious, thug. But a thug, and Batman was old.

Batman needs to use his skill because these enemies are stronger or faster than him. He can't beat them with brute force, so he has to use his keen tactical mind and advanced training. Against any enemies weaker than him, a nerve strike is unnecessarily complicated when a punch to the face will work just as well.

As for why he doesn't use them against his main rogues? Most of them aren't trained fighters, or stronger than him. The only exceptions I can think of are Bane and Killer Croc. So he just treats them like a mook: Take their weapons, punch to the face. Quick, efficient, effective, move on. It's rarely a case against Batman's foes of physically beating them, the trick is getting through their plan and catching them.

Because if he just kept one shotting bane or any other rouge everytime they fought it would be incredibly boring.

Batman doesnt do it because his writers dont allow him too. Plus on people like Killer Croc i doubt he could hit hard enough to even damage him.
