Giga Bowser (Final Smash)

Giga Bowser Transformation is Bowser's Final Smash in SSBB. It causes him to turn into Giga Bowser from Melee, gaining immense strength. It seems that this time, Giga Bowser is completely invincible, as in the screenshot to the right, Zelda, Pit), and [[Samus (SSBB)|Samus are shown attacking him, but to no avail. A caption in the update also says "He must be invincible!," further implying such an ability.
