Formchange

Formchange is a mechanic introduced in Kingdom Hearts III. Formchange allows Sora to change his abilities or the form of his Keyblade. Formchanges are triggered via Situation Command after achieving sufficient damage with a Keyblade. Certain Keyblades will also have the ability to Formchange a second time. Formchange is a mechanic that borrows cosmetic and technical concepts from Command Styles and Drive Forms both, and allows Sora to manipulate his Keyblade's form similar to the wielders from Kingdom Hearts Birth by Sleep.

Development

The concept of having the Keyblade transformed into different forms has existed since Kingdom Hearts II Final Mix with the Lingering Will being able to transform the Ends of the Earth Keyblade into different forms. The idea was incorporate into Kingdom Hearts III's gameplay to show the growth of Sora's skill as he trained and become a more masterful Keyblade wielder.

Guardian Form and Strike Form were originally referred to as Guard Form (ガードフォーム, Gādo Fōmu) and Power Form (パワーフォーム, Pawā Fōmu) in early gameplay notes and were considered Drive Forms before the formal introduction of the Formchange concept.
