He loses pretty quickly in the first skirmish. I can see him dedicated to it though...

Walking into the bat cave and going “wow, hah. Just look at all these Batman toys, such a funny story..”

Then he sets down the bat pistol he was toying with and sits in the bat chair, kicking back and saying “anyway I’m hungry, what’s to eat around here?” Even though he’s alone and no one can hear him.

First skirmish with the penguin will go something like .”mr penguin, yoiure fighting days are OVerrr” then he aims it at penguin and looks down the barrel with one eye squinted. Then he throws it to the side. “Tell me whyyy you do these things penguin man!” Shrugging “why do you have to be the bad guy!”

He gets hit on the back with a club, and that’s pretty much the end of it.
