To cover up the fact that William disappeared from Earth after X.A.N.A. took control of him, Jeremie created a clone of William. The clone was supposed to act just like William did so that nobody would suspect his absence, but the clone has often exhibited very dim-witted behavior and often required the Lyoko Warriors' supervision. The clone was created at the end of the episode Double Take. He was an Artificial Intelligence in humanoid form as Aelita was thought to be in the first two seasons.
He was deleted in Down to Earth, by Jeremie and Aelita, who created him, since the real William was freed from X.A.N.A.
X.A.N.A. managed to take control of the clone in Wreck Room to get William out of Lyoko, which caused Jeremie's program from the tower, that created the clone, to malfunction. In this episode, he was also elected the monitor of the Rec Room. This was undone by a Return to the Past.
When Jim stated that he was a real piece of work, the clone replied: "Oh, I'm not just any piece of work, I'm a digitally generated polymorphic energy field controlled by a non-evolving, basic, behavioral program." This, and the fact that he told Milly and Tamiya about the factory, told Jeremie that he had failed to instill the fact that Lyoko and all related subjects had to remain secret.
Despite, at least in theory, not being able to learn new behavior, he did start to show some emotions in A Lack of Goodwill, such as empathy for Milly and Tamiya, defensive behavior, and even playful behavior in the end. He didn't understand idioms.
Code Lyoko: Evolution
X.A.N.A. created a clone of William to steal the rest of Yumi's source codes in Rivalry. However, he was stopped by Ulrich, and it chased after him, where it confronted both him and the real William in the gym. However, Odd deactivated the tower and the clone was destroyed before it could harm Ulrich and William.
X.A.N.A. created another clone on Lyoko in The Codeless. This clone took William's virtualized form, but the orange lines on his costume were green and he had a black eye of X.A.N.A. on his forehead. It confronted Yumi and William at the activated tower. It tried to bring William back to X.A.N.A.'s side by saying the Lyoko Warriors were using him, especially Yumi. William fell under the clone's influence for a short time and chased Yumi down, but he later snapped out of it and stalled the clone long enough for Yumi to get to the tower, deactivate it, and destroy the clone. While the William clone in Season 4 was shown to be stupid, the William clone in The Codeless displays all the traits of a sociopath; he manipulates William and Yumi, he has a large ego, and he shows no remorse for trying to devirtualize Yumi.
In False Pretenses, X.A.N.A. made a spectre of William to confuse Odd, who also had two spectres of same image made to confuse William. To try determining who was the real Odd and William, they tried asking each other personal questions, where Odd asked both Williams if he had kissed Yumi yet, to which they both hesitantly refused to answer the question, saying "Uhh... pass." The William clone then asked Odd how many girls in his class he had dated, to which he threatened to devirtualize Odd, claiming he must be the fake since he could not recount the names of every girl he had dated. Odd then devirtualized both the William and Odd clones as Jeremie launched a program causing a halo to appear around each clone.
