Garage Kids was a short pilot that introduced the concept of Code Lyoko. The content no longer fits with Code Lyoko canon; The Lyoko Warriors have their Lyoko powers on Earth, particularly shown by Yumi's telekinesis. The atmosphere is darker, perhaps too much for a kids show. The characters' voices are different, and there was no mention of Lyoko or Aelita. The virtual world is called Xanadu instead of Lyoko.
Garage Kids got its character models and animation styles from Les enfants.
Code Lyoko: Prequel (2006)
Before the third season aired, there was a two-part prequel episode that aired, telling about how the Lyoko Warriors first met with each other and how they discovered the supercomputer, the virtual world of Lyoko, Aelita, X.A.N.A., and how the Lyoko Warriors were founded.
There was little linear storyline in Season 1. The big deal (return trips to the past do not resurrect humans) was only explained in Teddygozilla and the season 1 finale known as False Start, but all other episodes could be seen in any order, or even not seen, and you can understand the whole story. That's why we first see Theo in the episode Claustrophobia, and Taelia is completely forgotten after the events of The Girl of the Dreams. An interview with a writer team of French forum revealed that it was a channel's exigence: they wanted kids to understand the story even if they miss some episodes or even if the channel released them in the wrong order.
The original episode titles are in French and there are multiple possible translations for some titles. Therefore, the English titles are not official.
Code Lyoko Evolution airs on France 4 in France. During the season's original run, France 4 decided (without consulting Moonscoop) to re-air episodes 1-18 beginning in May, the week after episode 18's original screening, and ending in September. According to TV guides, a second hiatus is looking likely once episode 18 airs again. However, Canal J began showing the episodes in November, so the last seven episodes of the first season arrived earlier than expected.
Episode 114 of the series, The Trap, was released on iTunes France at the start of the unexpected hiatus, but shortly removed.
During the first hiatus, the last seven episodes of the first season had aired on the Hungarian and Romanian channel Megamax. Consequently, most bootleg episodes have the Megamax logo in them.
Cartoon Network USA will not air the season, but instead it will air on Kabillion. A pilot episode of the dub was released on February 28, 2013.
As of April 8, 2011 all seasons are on iTunes France to buy and rent.
This was the only season in which no cutscenes were included to any episodes since this season was live action.
