Code Lyoko - Season 1 Episode 2
Seeing Is Believing

Odd decides to start a music band with his friends. But Jeremy cant play, so they try to hire a drummer. In the end, the best drummer they can find is Nicholas (Sissis blond-haired crony). As the group argues over whether or not to let Nicholas join the band (Ulrich and Yumi: Pro-Nicholas. Odd: Anti-Nicholas, Pro-Naomi), Jeremie alerts them that XANA is planning to overload a pylon and send this massive electric current through the telephone wires to blow up a nuclear power plant. Just in the nick of time, Aelita, Ulrich, and Odd stop XANAs plan. At the end of the episode, Odd gives in and allows Nicholas to be the drummer of his rock band.
