Roll in Kingdom Hearts II
Rikuu appears(in a modified version of her Final Fantasy X-2 default outfit) with Yuna and Paine, forming a trio of treasue hunting fairies called the Gullwings. They were orignally working for Maleficent to spy onLeon and his friends, but were abandoned during the Heartless invasion of Hollow Bastion. Sora suggested that they help Leon, and Donald lied about him having treasure.

The three helped out during the invasion, but were angry at the deception. In the end, they forgave Sora, giving him a keychain.

Trivia
Rikku was originally set to appear in Kingdom Hearts, but was replaced by Selphie to avoid confusion between her and Riku.
