Characters

There's a few major charas in this new game, so lets do a quick run-though!

Jazz Jackrabbit
The main chara, if you will. Is big, is green, and is a rabbit :P That pretty much sums him up. He is Eva's love interest, so to speak, before she banished him after Devon came back. So he's not only on a quest to stop Devon, but to win Eva back.
Powers - Use his ears like a helicopter and can do an upper punch, which is useful for hitting upper blocks.
Overall gameplay - Not my choice chara. His ears ability is not only lame, but annoying in times. I have not found a use for it as of late. And its bloody hard to do his upper punch when you need it.

Spaz Jackrabbit
Jazz's little brother, respectivly, and my fave. He's crazy, he's funny, he's red ... just a cool new edition to the Jazz world. He is helping out Jazz on his quest, but to me he does most of the work :P
Powers - Has a wicked cool double jump ability, which can make you go father up and can do a karate kick, which not only sounds kool, but can hit those side blocks.
Overall gameplay - He would have to be my fave over Jazz. To me, his abilities actually account for something, unlike Jazz's powers. His double jump is just plain cool for getting into hard to reach places.

Eva Earlong
Jazz's love. Bleah, Queen on Carratos and the dame that needs rescuing in the first Jazz. basic stereo-typical female role ><

Devon
Evil turtle dude :P Wants to kill Jazz and Spaz, and Carratos in general.

SECRET CHARACTER! Lori Jackrabbit
Jazz and Spaz's sister rabbit! Said to have been in Jazz Jackrabbit 2 somewhere, but has remained a secret. This gal was supposed to appear in Jazz Jack 3, but as that has not come out, there is no evidence that this chara exsists in Jazz 2.
Powers - Said to have the powers of both Spaz and Jazz.
Overall Gameplay - If the above is true, then she will be the best chara without a doubt.
