X-men Mutant Academy is a pretty cool 2-D fighter with with 3-D rendered characters.  It plays a little bit like the Street Fighter Series but its  gameplay is excellent.  Each character has their own strengths and each are  pretty fun to play with.  Each character has a variety of Super Moves (some  of which I am still trying to figure out). The characters are Storm,  Wolverine, Cyclops, Gambit, Phoenix, Beast, Sabretooth, Mystique, Toad, and  Magneto. Although the number of characters you can use is small, its still  a very fun game to play.
