Chaotic was a Danish trading card game. It expanded to an online game in America which then became a television program based on the game. The program was able to be seen on 4Kids TV (Fox affiliates, nationwide), Jetix, The CW4Kids, Cartoon Network and Disney XD. It was brought over to the United States from Denmark by Bryan C. Gannon and Chaotic USA Entertainment Group, and produced by Chaotic USA Entertainment Group, 4Kids Productions and Bardel Entertainment. The trading card game came out 6 September 2006 in the U.S. and Canada.

Each card comes with a unique code which the owner can upload onto the Chaotic website. This allows the owner to trade and play online using their own card collection. The game was well known to be the only game with a TV show, an online game, and a TCG that were all integrated. However, the online game is currently closed.

The animated series was produced by 4Kids Entertainment. It was animated by Canadian studio Bardel Entertainment for season 1 and South Korean studio Dong Woo Animation for season 2 and 3. It is based on the Danish trading card game of the same name. Much of the plot is based on the original storyline of the Danish trading card game. The show ran from 2006 to 2010.
