Villains' alliances

The villains' alliances are alliances formed by multiple villainous contestants throughout Total Drama.

Dancing With Cowboys
In the beginning of the episode, Heather approaches Scott into forming an alliance and he agrees. Soon after, Scott approaches Sugar to join their alliance, and she agrees. After the challenge, the alliance agrees to eliminate Ezekiel but Sugar has other plans and decides to try and eliminate her enemy, Courtney. At the ceremony, Ezekiel received two of the three votes, and Courtney is ultimately eliminated because Sugar convinced her other team mates to vote against her as Courtney had lost the challenge. Realizing who voted off Courtney, Scott, thanks to Sugar, seeks revenge against Ezekiel, Ella, Sierra, Katie, and Jo. He is conflicted on Sugar however as him and Heather need her as an ally.

3:10 to the Horse of Losers
Heather and Scott are both angry at Sugar for her actions in eliminating Courtney. Heather particularly scolds Sugar and threatens to eliminate her. Scott on the other hand attempts to calm both down, and doesn't think it is right to vote off Sugar. Ezekiel begins to annoy the three of them and the others so they decide to target him again to hopefully get him eliminated this time. After their teams' second lost in a row, every member of their team vote him off, eliminating him.

The Root'nous Toot'nous Ludicrous
Seeking revenge against Sierra for eliminating Courtney, Scott tells his alliance to eliminate Sierra, both for eliminating Courtney, and for her lack of usefulness.

The Wild Bunch of Losers
Scott is seen taking a nap outside. He is suddenly woken up by Ezekiel, proposing an alliance. Scott accepts this on the grounds that Zeke vote with him and never betray him. However, Heather and Sugar don't trust Ezekiel, and refuse to ally with him, unlike Scott. From Scott's efforts, he manages to get his alliance to eliminate Ella, but he is confused when Ezekiel is eliminated.

Serpent Showdown
The alliance realizes that since the merge is coming around soon and Jo was very keen on being on a team with the Venomous Vipers, they feel that if Jo merges, she may try to form alliances with members of that team, which could effectively ruin Scott's alliance. Thus, Scott tells his alliance to eliminate Jo for being a possible threat later on, being cruel to all members of the team, and for being unlikable.

This Town Ain't Big Enough For the Nine of Us!
Scott attempts to form an alliance with Cody and Duncan, believing they may potentially join him, Sugar, and Heather. Not knowing that Scott is also allied with both of them, Duncan agrees, but Cody is unsure. In Heather's talent performance, she reads Sky's diary, which causes everyone to be mad at her besides the alliance, and Samey. Scott realizes the numbers aren't in his alliance's favor, and attempts to stop anyone from voting Heather, saying that at least the performance is creative. Heather asks Scott and Sugar to vote off Lindsay, to which they agree. Heather thinks she can also survive if she gets Katie on their side, but fails when Katie betrays Heather and votes her off in a 5-4 vote for Heather. The alliance is effectively hurt, worrying Scott and Sugar.

Yodelayhee...Who?
Scott, despite him not getting along with Cody, brings up to him and Duncan that they are outnumbered by the girls 3-4 and they should keep with their alliance. Cody refuses, as he doesn't want to work with guys like Duncan and Scott, but Scott angrily informs him that they're all he's got. Cody reluctantly agrees to the alliance but notes that once they get to the Final 5, it's every contestant for themselves. Sugar asks Scott later if he wants to reform the alliance with her. He seems happy at first, but says in the confessional that he wouldn't know what to do with Sugar if the guys alliance won over the girls and that it's hard for him to keep two alliances in mind, but realizes that she could help in numbers. Scott is sad when Sugar is eliminated during the challenge, thus ending the alliance, and forcing Scott to keep with his new one. When it comes to voting, Scott realizes that Samey is leading the girl's alliance and can tell they voted for him previously. Cody and Duncan follow his orders to vote for Samey, and in a 3-3 vote, Scott wins in the tiebreaker, leading to Samey's elimination.

The 5 Not So Lucky Horse Riders
Cody wakes up immediately wanting out of his alliance with Duncan and Scott, but is manipulated into staying after both of them threaten him that they'll eliminate him unless he stays working with them, knowing they'll need at least a 3-2 vote to their advantage. Cody reluctantly agrees, but is ashamed of himself to be part of an antagonistic alliance. When Katie eavsdrops on the guy's so she can find out their secret plans and manipulate one of them into joining the guy's alliance, Duncan and Scott threaten her to go away, whereas Cody welcomes her, and believes she can be a good member, confusing Duncan and Scott, as they know she is not trustworthy in the slightest, and force her to go away so they can discuss plans in private. Duncan and Scott both agree their best course of action is to eliminate Katie next, slightly angering Cody. After Duncan and Scott are both successfully the two winners of the challenge, they have the choice of eliminating someone. Scott sends Duncan a letter from the hospital because of his injuries, asking that Duncan make the decision to eliminate Katie. Although Scott brings up that Lindsay is a threat in the letter, Katie is more manipulative. After contemplating his decision, Duncan says that their decision is Katie, resulting in her elimination.

Three Enemigos
Scott is dissapointed that Cody is eliminated, as even though he disliked him, he found him very trustworthy, yet still realizes the math of voting is still in his and Duncan's favor. They both agree that they should take each other to the finale.

The Final Finalé
Duncan roots for Scott to win in the challenge against Lindsay so that their alliance is successful, which is exactly what happens, making Duncan cheer in delight.
