Xana

Xana is still bent on taking over the world, but in this series he has some problems. Sowhere toward the end of the eighth episode, Team Lyoko accidently unleashes Zora, an AI originally designed to capture Xana and extract the location of Franz Hopper(Leading us to believe the Men and Black created her.) but she is quickly subdued by Xana's forces, where she is brainwashed by the Skypazoa. Now the new general over all of Xana's forces, Zora serves her new master and eventually destroys the supercomputer's core while Graham is scouting on Lyoko, cutting off Team Lyoko's link with Lyoko, and cutting them off from Graham. Jeremie is able to reboot the supercomputer but cannot materialize Graham until the Supercomputer's core is fully online. Graham is sent to get the Sword of Lyoko, which is the only thing that can recreate the core, but it is taken by Xana when Graham aquires it. Graham is then sent to a new sector inbetween Earth and Lyoko and must find a way back to Lyoko so he can steal the sword back while he is chased by the mysterious Maelstrom(Pronounced Mail-Storm). He eventually suceeds, with help from Aelita, and together they get back the sword and Graham is materialized. Maelstrom shortly thereafter takes the sword and fuses it wih Darkness, turning it into the Sword of Maelstrom. He then builds a wormhole so that he can escape from the computer and destroy the world. Xana is put in a coma in the process.
