Alliance

Throughout the show campers decide to make or join an Alliance to help themselves or to get rid of others. Many campers had an alliance or were part of an alliance in both Total Drama Island and Total Drama Action.

Alliances

 * LeShawna's Alliance: A new alliance in Total Drama Action. LeShawna asks Duncan and Harold to be in a alliance with her in the episode One Flu Over the Cuckoos. Harold refused to join an alliance with Duncan, claiming he's a "worthless punk", though he admitted that, if Duncan were not to be in the alliance, he would join. Duncan just laughs at the idea and jokes about it, angering LeShawna. LeShawna's motivation for forming this alliance is to "keep Heather off her back", as LeShawna's only other defense against Heather was Bridgette and Gwen who were both eliminated in past episodes. With Heather eliminated in Million Dollar Babies, LeShawna tried again to form a alliance between the three in Dial M for Merger, but with a new motivation: To make it to the final three. Harold and Duncan still refused to work together until LeShawna told them to cooperate just to get closer to the million dollar prize. Harold and Duncan reluctantly forms the alliance with LeShawna. This alliance ends quickly with LeShawna's elimination in the next episode from the second Guys alliance.


 * Heather-Harold Alliance: A new alliance in which Heather and Harold are in. Harold says he'll only gonna be in an alliance if it is called some thing else. The status of this alliance is unknown, as Heather was eliminated before the alliance took affect.


 * Chef's Illegal Alliance: A new alliance in Total Drama Action. Chef Hatchet approached DJ about possibly forming an alliance. In exchange for toughening DJ up to make him a better competitor, DJ would give Chef half the prize money if he were to win. It is the only one with 2 people with the same voice actor. The alliance ends as DJ confessed to everyone about him and Chef teaming up in The Sand Witch Project, which also got DJ eliminated.


 * Duncan's Guys' Alliance: After realizing that there are more girls then boys, Duncan has Owen, Geoff, and DJ join a guys only alliance. He decided to have all the guys vote off Bridgette since she is the most athletic of the girls left. Since Geoff has a crush on her Geoff didn't vote her off, resulting into the Guys hanging Geoff upside down from a tree.


 * Duncan-Heather Alliance: In the Wawanakwa Gone Wild!, Duncan decides he needs an alliance so he teams up with Heather. Duncan tells Heather that he'll take them into the final two. When Heather gets paralyzed Duncan cleans the bathroom for her. This alliance seemingly only lasted one episode, but it was mentioned in "Are We There, Yeti?" when Duncan was eliminated by Heather.


 * Gwen and Owen's Freebie Alliance: During the Triple Dog Dare semi-final competition, Gwen decided to ally herself with Owen and asked him to help her take down Heather once and for all promising him half of her winnings if she wins. Owen agreed and gave half of his freebies to Gwen. It worked and Heather was finally eliminated from the competition.


 * Heather's Alliance: Heather is the first one to make a alliance. Her plan was to take two other campers to the finale three. She chose Lindsay and Beth due to Lindsay's stupidity and Beth's desperation. Heather made it clear though that she is the leader. She mostly abused her role as such by making her alliance do stuff that involved nothing of the challenges, This caused Beth to quit her alliance. Later in the show, Izzy joins for unknown reasons, although quits soon afterward without much of a complaint from Heather. After the Bike race though, Lindsay lost because of Heather and had to go off the island. It is revealed before Lindsay left though that Heather never really liked her or anyone who was in her alliance. Heather may have another alliance with Harold in Total Drama Action, though with her elimination it has ended.


 * Justin's Alliance: In Beach Blanket Bogus, Justin admits in the confessional that he will try to manipulate Beth's feelings and use her to make it to the finals. This may also involve Lindsay and Owen. However, this alliance never took hold, since the girls were able to break their obsession with Justin before he wanted to use them.


 * LeShawna's "Eliminate Heather" Alliance: After Gwen sees Heather kissing Trent, she tells LeShawna and this provokes her to start a alliance to convince almost everyone on the island (minus Heather's Alliance and Trent) to vote either Heather or Trent off the island. When Heather gets invincibility they have to vote off Trent. After Trent is voted off though, Heather admits that it was all a trick to get either Trent or Gwen off. Gwen, Bridgette and Leshawna continue to have an alliance and try to vote Heather off.


 * Second Guys' Alliance: Formed by Justin in Super Hero-Id. Once he points out that the guys are outnumbered, four to three, he convinces Harold and Duncan to form an alliance with him. They are responsible for the elimination of LeShawna, and is no longer in effect since both Justin and Harold are eliminated as of 2008: A Space Owen, though its possible that since Harold and Duncan rarely got along anyways, it ended when Justin was eliminated in The Princess Pride


 * Courtney's Alliance: Formed by Courtney in Crouching Courtney, Hidden Owen. She points out that the girls are outnumbered by the guys (two to three). Beth is her only alliance member so far. Courtney says that she will do anything to get Beth in an alliance with her, so she offers Beth snacks and does tasks for her, like cooking the poisonous fish. This alliance seemingly ended the next episode, yet another short alliance.


 * Chris' Secret Alliance': Formed by Chris before Rock n' Rule. Chris let Owen return after finding out Owen's Family is in debt due to buying a cheese cellar, but under one condition: Sabotage the contestants Unfortunately, Owen's guilty conscience doesnt help with his antagonistic ways, which in the end gets him fired, thus ending this alliance.
