Editing Head-On Assault

The move acts similarly to [[Bowser]]'s [[Bowser Bomb]] and [[Yoshi]]'s [[Yoshi Bomb]]. On the ground, the Mii leaps diagonally upwards into the air, flips upside down and heads straight to the ground, landing on its head. The grounded version has an initial hitbox that leads into the main hit. In the air, the Mii will skip straight to flipping upside down and headbutting. The move can actually catch the ledge's sweetspot only if used while facing one, making it usable for [[edgeguarding]].

The headbutt has the ability to [[bury]] opponents in [[Super Smash Bros. 4]], similarly to [[Zero Suit Samus]]'s [[Flip Jump]], though its impact range is rather small. The attack also has heavy ending lag and deals low damage to shields, making it easily punishable. As such, the move is rarely used in competitive play, apart from hard punishes or setting up [[sacrificial KO]]s while having a stock lead.

In ''[[Ultimate]]'', the move is visually the same, except the move does not bury opponents. In addition, the move is now a multi-hit attack, and deals heavy shield damage, being able to break a full shield if both ground hits connect. However, the move's final hit now deals less damage if initiated from the ground. The move also possesses a rising hitbox in addition to the initial scoop hitbox, however, the rising hitbox can be [[airdodge|airdodged]] out of, limiting the move's use as a combo ender.
