The Digi Colette is the main transformation device from Shugo Chara!: Cosmic Rush. In order to transform with it, the characters need to have his or her Guardian Character inside of it, and shout out the phrase "Digital drive, Unlock!", additional to their respective colors that they are on. Amu is the only one to not receive a Digi Colette, because she have failed the Guardian Exam twice, and stuck by being a Guardian Character for eternity. The "Chara nari!/Character transformation!" was cut out, but their title were placed before their alter ego (ex. Guardian of Fire, Blazing Dynamo!, Jack of Spades, Samurai Soul!, etc.)
