| I'd say Star Rod Bowser. He's absolutely invincible to the point that nothing can pierce his defenses save for the combined power of all seven Star Spirits. And he even overcomes that so that the Star Spirits have to upgrade to the Peach Beam. Before Mario gathered the Star Spirits, Bowser beat him with, like, two attacks. Compared to that, Giga Bowser accidentally falling off the edge of Pokemon Stadium seems kind of pathetic. |
