The space swindler Dolltaki is employed by Dr. Myuu and given his strongest Machine Mutant, Luud, in Age 775. Dolltaki uses his skills as a swindler to create the scam religion Luudism on planet Luud, and begins gathering energy from its adherents.

He takes a fancy to Pan and has her transformed into a doll, but in the end he receives the same destiny and is transformed into a doll himself and absorbed by Luud. Inside the giant Machine Mutant Luud, Dolltaki is forced by Pan to reveal Luud's weak point. Goku and Pan destroy Luud and all the people who were absorbed regain their bodies.

Dolltaki runs away from Planet Luud and retreats to planet M-2.
