Each character in the game has an individual special attack which inflicts more damage than regular attacks, so you'll have a lot choices to conquer your opponents and win the fight.
The two playable characters from Total Drama in Cartoon Network TKO are 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 is stomping on the ground, causing rocky spikes to rise up and injure his opponent. Chef Hatchet's special attack is throwing a sink at his opponent.
