Most of the Justice League have one weakness that stops them dead in their tracks. I thought Batman was immune. Turns out he does have one weakness though - and it took an evil duplicate to find it… Batman can’t handle a nipple cripple.

Batman’sWeakness

Cover of Justice League of America #13 - Riddle of the Robot Justice League!

Batman’s nipples are so sensitive it takes just one tweak and he collapses in a ball. Superman has his Kryptonite, Green Lantern the colour yellow. Batman has glass nipples. Perhaps that’s why Batman and Robin accentuated them so much - it was extra protection.

I’ve altered the image a little. These old Justice League comics have such cluttered drawing. And the writing was awful compared to what I’m used to today. Still - they do have some fun moments.
