Dude, give up already. Admit you lost and move on. Energy blasts/waves/beams from your hands were put on the map in Dragon Ball. Vegeta was the first to do it with a finger gun pose. And if you're going to go the nitpick route to try and move the goalpost, I'll throw one back at you. Yusuke uses one finger to fire, Goku uses two. By your own logic, that means it's not a ripoff.
