@Jazzy_Butts He's got Ki training in the comics, just not DBZ style energy blast Ki. But, it's part of how even though he's a "normal" human he's faster and stronger than humanly possible, heals fast, that sort of thing. He also uses it to conceal his presence and detect others. But he uses it with like five other things to do any of that. So I mean, he'd probably also pick up DBZ style Ki usage real fast, since he's already got the basics. Think it was Dick Dragon that taught him.
