Code Lyoko (2009)
Code Lyoko tells the story of four boarding school students enrolled at Kadic Academy: Odd, Ulrich, Yumi, and Jeremie, who discover an artificial intelligence unit, Aelita, who is the sole inhabitant of a digital world known as Lyoko. An evil program of the Supercomputer that houses Lyoko, X.A.N.A., plots for reasons unknown on destroying all humans on our fair planet. X.A.N.A. attacks Earth by using Towers to hack into electronic devices, possess objects, or take control of non-sentient organisms. Our four heroes must then escort Aelita to the activated Tower, where she deactivates it, and saves humanity in the process. X.A.N.A. develops many different strategies to try and kill our heroes, such as making them listen to music that makes people go into a coma and die, imprisoning them within Lyoko, putting them inside a semi-functional virtual world that looks like Earth, trying to send two trains carrying poisonous chemicals at each other, and various other schemes. During this time the main characters deal with their school lives, fall in love, become rivals, yell at each other, go crazy, and generally deal with their split lives.
