Don't know if this is a good idea but here goes nuthin..My idea is to have a 4th bar added underneath the KI bar called energy. What this bar would do for you is prohibit multiple blasts (like 5 final flashes in a row, you never see that in the show). So if you were too fire a final flash itd take away a lot of ki and a little of the energy. This bar would also make kaio-ken possible, because you would be able to quadruple your power level or whatever and while your doing kaio-ken id drain your energy. I like the one idea from DMZ where you go unconscience if you lose so much of stamina or whatever, same with the energy bar. You would black out if you were to use too much of your energy too fast..So is this idea any good?
