>>96989254>people having trouble understanding this sceneThis is what faggots get like when they started with Z and didn't the original. You can't move during huge blast attacks as a function of how they work. The concentration of energy, and focus of the individual, preclude movement. It's too dangerous to try it normally. I believe this is explained briefly by Roshi, if I'm not mistaken.
Except Goku has UI to autododge for him while he puts his mental focus on the attack itself. Thus making it possible to move while doing it. Whis even points out he's relying on the autododge while using his mental focus entirely on the attack itself.
