Ultimate Form

Ultimate Form is a Formchange in Kingdom Hearts III. It is triggered exclusively by Ultima Weapon's Formchange, it changes Sora's clothes to a design very similar to Final Form. It allows him to teleport around the battlefield and wield multiple swords in battle, overwhelming enemies with fast and powerful swipes that also possess great range.

Appearance
Ultimate Form turns Sora’s Coat, Gauntlets, and Shoes silvery white (reminiscent of Final Form), while his pants gain a swirl pattern. His shirt and pant pockets remain their usual black.
