You don't need super powers when you're naturally a bad ass!
Batman vs. The Joker
Could watch this all day...
Marvel Vs DC: Equivalent Characters these are the best marvel vs DC pair ups I've ever seen!
Batman and his Robins.
Venom & Spidey
I would take a Robin over a prince ANY day!
The only problem I have with this is batman isn't a prankster. He's too serious. I can see The Flash putting GL up to this. Especially since Barry and Hal are Best Friends out of costume.
If superheroes had part-time jobs…<<< I don't know about you guys, but I'd love the flash to get my pizza to my house faster!:
Harley Quinn, Catwoman & Poison Ivy
