This page is about the Miscellaneous Characters in the Code Lyoko franchise who are not noteworthy enough to have their own pages, but have more information than just their names in the List of characters page.
Peter Duncan was a french criminal. Duncan was arrested prior to the beginning of "Common Interest" for various crimes, including art theft, safe cracking, kidnapping, and bank robbery. He claims to not talk to cops. X.A.N.A. possessed him during prisoner transport. Duncan then escaped, and walked through the woods to a uranium transport truck. Duncan stole the uranium, and walked back to the Supercomputer. He passed out several times on the way, due to supercomputer failures. He kidnapped Jeremie Belpois from The Hospital, and forced him to install the new rod. Duncan attacked Jeremie after the rod was swapped. Once the tower was deactivated, the Lyoko Warriors dropped him off at a police station.
