Bowser (SSBB)/Forward smash
Bowser rears back and then performs a very strong headbutt. It starts off with a weaker hitbox which then leads into a much stronger hitbox. It is the most damaging forward smash in the game if Bowser connects both hits. Both hits are guaranteed against shielding opponents, with no gap between the hits. It KOes Mario at 55% at the ledge and 80% from the center of Final Destination if both hits connect, while fully charged it's extremely powerful, KOing at just 20% at the ledge, and 40% from the center.
