Frankie (nickname given by Theodore) is Doctor Frankenstein's Monster and a main character in the direct-to-video film Alvin and the Chipmunks Meet Frankenstein. He was created with dead human parts twice by Frankenstein. The first time the Doctor took him apart because he was terrorizing the townspeople. Frankie is seen as a monster because of his outward appearance. After he brings back Theodore's bear, Theodore realizes there's good in him so Frankie is taught how to interact with other kids. Alvin later teaches him how to speak and drive.
