Stream cartoons Code Lyoko Prequel Realizing the danger the supercomputer represents, Jeremie takes the advice of his new friends(Ulrich, Odd, and Yumi)and decides to shut it down, but not before bringing Maya (Aelita) into the real world. Meanwhile, the strange events become a consistent problem when an electric orb begins hunting Jeremie and his friends. In a trip to Lyoko, Ulrich, Odd and Yumi work together to get Maya to the tower under the assumption that it will bring her to the real world. This assumption is ultimately false, shutting down Xana’s attack rather than materializing her. Maya (who discovers her real name of Aelita when shutting down the tower) suggests they shut down the supercomputer, but the group decides to help Jeremie until Aelita is in the real world. Yumi then says they have to help, because they are Lyoko Warriors.
