Garage

Garage Kids was originally intended to be the name and concept for Code Lyoko. They decided to switch to the current name and concept instead of sticking with what is seen in the five-minute pilot. The original hook of the series is seen below. Most of it is still true of Code Lyoko, except for some minor details.
This is the original plot for Garage Kids. Much of this still holds true for Code Lyoko, though various names and places have been altered.
Lyoko is portrayed quite differently in Garage Kids, being called "Xanadu" instead. The antagonist appeared and acted very much like Xana in Code Lyoko, but was given no name in Garage Kids. The three main fighters, such as Yumi, with her telekinesis, were able to exert their special powers outside of Lyoko. Aelita does not seem to exist in Garage Kids, and no character models of her were ever made.
Garage Kids is similar in many ways to Code Lyoko, but several stark differences exist, as well. The differences are seen in the minor details, such as outfits and backgrounds. The similarities can be seen in the larger details, such as the overall theme and characters involved.
