I just found this site that has a few test to see which character's you are like from different shows, games, and comics. There's the Simpson's, DBZ, DC comics, Dilbert, Yu-gi-oh, and Mortal combat.
Click here to take the test. These are what I got:

Simpsons: Bart
DBZ: Goten
DC Comics: Flash
Dilbert: Catbert
Mortal Combat: Kung Lao
Yu-Gi-Oh: Kaiba
