Cartoon Network TKO (Titanic Kungfubot Offensive) was a crossover game, which featured Total Drama Action, produced by Cartoon Network. The game was first released in early 2009 but has since been removed from the site.
Each character in the game had an individual special attack which inflicted more damage than regular attacks, so you would have a lot choices to conquer your opponents and win the fight.
The two playable characters from Total Drama in Cartoon Network TKO were Duncan and Chef Hatchet. They were both added on June 20, 2009, right after the premiere of Total Drama Action on Cartoon Network.
Duncan's special attack was stomping on the ground, causing rocky spikes to rise up and injure his opponent. Chef Hatchet's special attack was throwing a sink at his opponent.
As of 2011, the player could earn badges for their profile by achieving certain objectives within the game. One of the badges featured Chef and Duncan together. It could have been earned if the player won a game playing as both Duncan and Chef.
Cartoon Network shows that had aired new premieres and episodes from 2007-2010 were all represented with characters in the game. These shows are: Adventure Time, Chowder, Ben 10: Alien Force, Ben 10: Ultimate Alien, Generator Rex, Johnny Test, The Marvelous Misadventures of Flapjack, Sym-Bionic Titan, The Secret Saturdays, and Total Drama.
