Guys' alliances

The Guys' Alliances are alliances formed by multiple males throughout Total Drama.

Hide and Be Sneaky
After the events of Search and Do not Destroy, which ended with Trent leaving, the guys were outnumbered six to four. As a result, Duncan got his friends DJ, Geoff and Owen to gather into a cave during the challenge to discuss the situation, and to form an alliance before the girls could eliminate all of them. Owen felt guilty about joining it, until Duncan forced him to join. It was formed to make sure that a guy won Total Drama Island. The only thing that the alliance actually accomplished was Bridgette's elimination.

That's Off the Chain!
The alliance was mentioned by Heather. Plus, the guys interacted together a lot in this episode.

Hook, Line, and Screamer
It is presumed that the alliance dissolved after DJ was eliminated in Hook, Line, and Screamer.

The Very Last Episode, Really!
Regardless of the alliance disbanding, a member still managed to win Total Drama Island. All the members rooted for him to win.

Total Drama, Drama, Drama, Drama Island
Owen, DJ, Tyler, and Cody form a guys' alliance to find the case with the million dollars in it. To become a stronger team, they tie themselves together with rope. The team is the first to find the case, but ultimately lose it to Harold and Heather when they drop it while Owen is going to the bathroom. They regain the case again but lose it after Courtney steals it. DJ and Owen make it to Total Drama Action, while Cody and Tyler do not.

Super Hero-ld
This is the start of the third stable guys' alliance. At the beginning of the episode, Justin points out that they guys are outnumbered and need to band together to overpower the girls. All of the guys agree to work together and the second guys' alliance is formed. After the superhero challenge, the guys try to decide which of the girls they want to eliminate. Justin wants Courtney eliminated, but Duncan reminds him that she had invincibility. Duncan suggests getting rid of Leshawna, much to Harold's refusal. After Courtney (who was convinced by Duncan) convinces Harold to send Leshawna home, Harold votes her off. The guys prevail and Leshawna is voted off, to the other girls' surprise, but Harold confesses his actions to Leshawna and begs for forgiveness. She forgives him before leaving in the Lame-o-sine.

The Princess Pride
Duncan is out of the alliance in The Princess Pride when he and Justin start fighting over Courtney. In the final challenge, Harold and Justin keep the alliance going to defeat Duncan, but then Justin betrays Harold. When Justin is eliminated, Harold and Duncan show no concern at all, indicating that the short-lived alliance had ended.

Trivia
