Shape-Shifting

Shape-Shifting refers to the ability to change one's shape at will. Within the Goop series, shape-shifting is the special purple gooptar power of the franchise's main protagonist, Goop. As with every purple gooptar before him, Goop is imbued with incredible powers, the most important of which is his ability to transform his body into other forms, granting him new abilities and powers temporarily.
