I also think that your starting movement and defence values are too high. Consider that Cyclops and Wolverine only hav movements of 6 and 8 repsectively. Karma has nothing that would make her faster then they are. Their Defences are only 16.

You have the right ideas for types of powers, but too much of it.

Correct me if I'm wrong but hasn't Cannonball expanded his powers to be able to use it as a ranged attack?
