Hyper Hammer

Hyper Hammer (ブーストハンマー) is a Formchange in Kingdom Hearts III. It allows the user to transform the Keyblade into a hammer and bombard enemies with strong attacks.

Design
Hyper Hammer transforms the Keyblade into a giant hammer. The hammer's head appears technological in design, boasting a rocket booster to deliver powerful attacks.

Mechanics
In Kingdom Hearts III, Hyper Hammer is the first Formchange of the Favorite Deputy Keyblade, associated with Strike Form. It has a base duration of 30 seconds and a maximum combo length of 5. Its ground combo has Sora leap forward and slam the hammer into the ground in front of himself, spin it around himself, slam it in front of and behind himself, slide it forward before swinging it upwards, and finishing by enlarging the hammer and slamming it on the ground. The air combo is identical to the ground combo, though the slams are replaced by Sora spinning the hammer vertically.

Hyper Hammer uses Proximity-style Magic.

Abilities
Alongside the abilities from Strike Form, Hyper Hammer also has access to Guardbreaker.
