Video gaming features plenty of memorable character duos: Ratchet & Clank, Jak & Daxter, Banjo & Kazooie, and Mario & Yoshi, but one of the most unexpected combinations has to be Batman and the Joker. Ever wonder what would happen if the bat and the clown had to team up to take out goons and work as a team? This video clip made with assets from Batman: Arkham Asylum makes it happen. Some say that this is a Batman: Arkham City clip, but I just don't see it. There's nothing new happening in this clip when it comes to character models, environments, or voice acting, and I sincerely doubt that the Arkham sequel would so blatantly reuse so many elements from the first game. Still, it's a fun bit of animation and a solid vote for a brief alliance between the two characters.
