Aside from good Cole being canon, there is actually a bigger difference between the two other than power.

See, good Cole is precise, preferring to deliver maximum damage to his target without harming others, as well as overall more defensive, with his ice abilities creating cover or a shield for absorbing ranged attacks for energy, and allowing him to jump up higher.

Evil Cole, on the other hand, goes for maximum damage all around, tearing through even civilians around him to take out his target and centers much more on offense and devastation, usually not taking care of himself aside from draining the life from foes and even civies.

Though both Coles can use bio leech, since the ability is never locked to good Cole.
