Kuzclone is an episode from The Emperor's New School. In it, a class assignment "My best friend" makes Kuzco realize he has none. He claims he needs no best friend, but for the occasion invents one: his alter-ego Brad Sca-Llama. Informed by Kronk, Yzma decides to actually make a Kuzco-clone, who assumes that name, to take Kuzco's place and fail all his assignments.
