9. The Rainbow Suit
Now Batman has never really been the most colorful person. Usually sticks to his blacks, his greys, and his blues. And that is why this issue of Batman sticks out the most and is well remembered.
Who wouldn't remember The Caped Crusader fighting crime in suits based on the colors of the rainbow? From a reference in The Brave and the Bold (watch it!) and even having his own action figure.
The entire issue involves Batman trying to protect Dick Grayson's identity after he breaks his arm. By wearing multiple suits, one that is literally just a rainbow suit. We still don't understand how that logic makes sense but who are we to question the Dark Knight.
Even if he is wearing a bright pink suit while punching bad guys.
