So the more powerful you get the more reaction out of the environment? SSJ Goku must shake the ground when he powers up lol, a lot more rocks come up and the power extends further out and possibly causes a shockwave effect when you jult up power. I'm just saying if you're a super saiyan, i'm pretty sure powering up would look badass, and you would be able to feel the amount of power that you have.
EDIT: Just reread this...it would be kind of cool to have a jolt button. If you don't have time to power-up, you could just use some of your endurance to do a quick power increase.
