Code Lyoko - Season 4 Episode 10

When a comet passes near Earth, X.A.N.A. uses a laser-equipped military satellite to split it into chunks, simultaneously aiming the bulk of it directly at the factory. Aelita, Odd, and Ulrich are exploring the digital sea at the time, and X.A.N.A. traps them with a firewall to prevent them from stopping the attack. Meanwhile, Yumi is stuck at school and, when informed of the attack, works to evacuate the school. Jeremy tells Yumi to connect his laptop to an antenna to tap into the military satellite and destroy the comet. She does so with help from Hiroki and Johnny. However, X.A.N.A. prevents them from doing so. Unable to stop the attack, Aelita reasons that X.A.N.A. is more concerned with taking her prisoner than destroying the Supercomputer, and to test her theory, she has Odd devirtualize her. Having guessed correctly, she watches as X.A.N.A. destroys the comet and calls off his own attack on his own accord.
