XANA Warrior: William Clone

William Clone (voiced by David Gasman) was created by Jeremy to fill in at school so no one would know that the real William was gone. The clone wasn't very smart though. It had enough common sense not to do dangerous things, and it would answer insults in a very plain fashion, not getting mad as it didn't know what the person meant. It had no emotions aside from confusion and happiness. So it would say the logical answer to jokes. This would often confuse people, occasionally with humorous results, as those around him believed William was playing dumb. He was created By Jeremie Belpois. He is in 9th Grade and is a minor character.

In one episode it was shown to demonstrate rage. The real William, possessed by XANA, returned to the real world and attacked Milly and Tamiya (who had found the factory and were inside the control room at the time) because they got in the way of XANA's plan. During this time the clone protected them using abilities equal to possessed William (super speed and strength etc.), performing well against the original until XANA-William hacked into Jeremy's console and deactivated his program, causing it to disappear.

The first time Jeremy made a clone was in the episode "Double Take" and the clone was of himself to fill in at school so he could work longer. He succeeded activating a tower for the first time. It worked for a while, but XANA-William attacked the tower in attempt to take control of the clone, and the Lyoko warriors, in new suits and weapons that Jeremy had been working on, were sent to stop him. They managed to defend the tower and stop William. Aside from that and having to explain everything to it, the clone of William after that worked just fine. Jeremy later put up a defense program to prevent XANA from further attempts at taking control of the clone.

The only other recorded time XANA took control of the clone of William was in the episode "Wreck Room." Jeremy had written a program to free the real William, but it malfunctioned and bugged up the defense program on the tower maintaining the William clone in the real world. At this point XANA had XANA-William go and corrupt the tower so it (XANA) could take control of the clone. The possessed William did succeed, with a resultant attack on the team in the real world. In the end the team managed to fix the tower and thus the clone. They returned to the past to keep Lyoko and the clone of William a secret.

In the episode "Down to Earth" the team had finally saved real William from XANA returning him to the real world, where William’s parents had shown up for a visit, which wasn't going well. William's parents had become suspicious of the clone due to its strange behavior and abnormally happy disposition, which were opposite of their experience with him. When the team and William got to the clone and William's parents, his dad had just declared that he (the clone) wasn't his real son, as he was too happy and totally obedient. The real William was kicked out of one school because he put stickers all over the Principal's car. The team distracted William's parents and Principal Delmas, and while they weren't looking Jeremy deactivated the clone causing it to disappear. At which point the real William quickly took its place, and acted like himself, getting his parents to calm down and clearing everything up (without anyone knowing about the clone). Jim was the only person who saw the clone disappear, and of course didn't understand what had happened.

William Clone is listed as a supporting character because he is only a copy of a main character, and he is only in the show until the team rescue the real William.
