@Yusuke52: not in second game after getting the new elements.
Aang would win pretty easily considering the water element, maybe if you switch aang with a fire bender who can manipulate lightning like Azula it could be a better match up, but even then I see Cole losing
BS, end of the second game cole destoyes any fire bender, he can freeze them and shatter them into tiny peices. And this is adult Aang he would stomp any fire bender as well, seeing as he has full controll over Avatar state, 4 elements, and energy bending(can take there bending away).
Cole wins this hands down by Spamming fire storms, freeze bombs, and giant thunderbolts from the sky. Let's not forget great regeneration. Bad Cole absorbed "The Beast" which regenerated from a nuke! Also, Kole has a few cool telekinesis tricks. Furthermore, being at at a modern day city according to OP, cool can use his magnitisim to squish Aangy with any nearby car after freezing him. and cherry on top is Cole is a much better fighter than Aang.
