Drive Form

A Drive Form (ドライヴフォーム) is a transformation for Sora in Kingdom Hearts II. It uses the power of one of Sora's party members to use abilities otherwise unavailable to Sora. The first is unlocked after Sora speaks to Flora in the Wardrobe of the of The Mysterious Tower.

Story
Upon speaking to Flora, the Three Good Fairies grant Sora new clothes. They then give him a Drive Orb, which gives him the ability to transform, and use a Sub-weapon. They mention that Sora's garments have other special powers, though he'll have to discover what they are throughout his journey.

Inspecting the room further reveals six (five in the original PlayStation 2 release) mirrors, one for each Drive Form. Each mirror grants Sora a vision of using said Drive Form.
