Since everyone is pretty familiar with the caped crusader, I don't think I need to write a bio for this figure. I figure this would be an outfit Batman might use if he needed a little more armor between himself and the super villains he fights.
This custom came about when I bought a group of G.I. Joes and found this neat cape attached to a yellow Alley Viper figure. I thought "Hey, that looks pretty neat" and came up with this armored Batman figure.
