2 Gun Kid is a pretty good shot and he has performed some pretty remarkable feats in the past. That being said, he’s not ready to challenge a warrior who can fight at hypersonic speeds. Kallen can destroy cities in an instant while inside of her mech and she’s a decent fighter without it as well. 2 Gun Kid can hit his mark as many times as he wants, but his bullets will not hurt the mech. Kallen wins.
