Code Lyoko is about a group of four boarding school students enrolled at Kadic Junior High School: Jeremie Belpois, Odd Della Robbia, Ulrich Stern, and Yumi Ishiyama. The students travel to the virtual world of Lyoko — which is found in a supercomputer housed in the basement of an abandoned factory near the school — to fight against a deadly multi-agent system named XANA and prevent him from taking over the world. In the first season, they also tried to bring a virtual being trapped on Lyoko, Aelita Schaeffer to Earth.
I like this anime since I watched it in 2003-2005. It was one of my first 3D animes. Idea is good and the story developpment is nice specially from a season to another. I liked that caracters powers or weapons "evolution" too.
This a nice anime specially for 10-15 years old but I'm 25 and still enjoy it.
