the 100x big-bang kamehameha could i think take-out the entire health-bar (or at-least over half a bar for sure, i think) in budokai 3 if done right
that was good
in games like burst-limit, captain-ginyu's body-change could be a game-changer, if u hit it at the right-time. even-tho it's not op in the sense u mean it, i think.
