A colossal transformation powered by dark energies, Bowser first took on this fearsome form as a boss in Super Smash Bros. Melee. He reprises that role in this game, guarding the Molten Fortress in the Light Realm, using a more powerful version of the Koopa King’s usual moveset. Bowser also transforms for his Final Smash, entering the background and unleashing a ferocious Giga Bowser Punch.
