List of alliances

Alliances consists of two or more people who work together to get each other farther in the game. Alliance typically vote together, or simply vow to never vote anyone else in the alliance. However, these can easily be betrayed and a player could take advantage of the alliance in order to hurt it later on. Usually, an alliance's main goal is to make sure that only the people involved in it are left standing. This usually succeeds, but is prone to failure.

Below is a list of alliances throughout the seasons. Please note that some of the alliances may be a bit weird, as in earlier seasons, alliances were made with anyone and by anyone.

Byron's Total Drama Island
The first alliance formed was between Alejandro, Brick and Lightning, formed by the former right after the first elimination. Unfortunately, Lightning dropped out of the competition soon afterwards, so Alejandro pulled Rex into the alliance, who ultimately agreed. Later on, they also invited Katie.

While Shawn's and Liz's eliminations were mostly caused by themselves, Dawn would soon be a victim to this alliance. The foursome Ant alliance would target Courtney and Raven next, but they merged before this could happen.

Soon after Alejandro's alliance was created, an inter-team alliance between Courtney, Diana, Izzy and Raven was made. The four girls usually told each other who to vote on each team, which would be the cause of Jay's elimination. With the alliance still together, Courtney was swapped over to the Adventurous Ants, Raven's team, due to their low numbers from Liz's elimination.

These two alliances were the main opposing alliances during the season, and would become more prominent during the merge phase

Only one more alliance was made. Though barely ever used, Katie, Raven and Rex made an alliance to suspect Alejandro's suspicious behavior, as he tried to get the trio to target each other. With this, Raven was more desperate into wanting Alejandro out, but Katie stuck to her alliance with him.

When the merge phase came, San and Dawn returned to the game. With Dawn's refusal to be pulled into any alliances, the girl alliance pulled San into their alliance after Raven's drop-out. With the 4 votes, they also convinced Rex and Brick into voting for Alejandro, to which the duo agreed. Thus would be the cause of Alejandro's elimination.

The girls also added Gwen to their alliance to secure numbers, but when the girls wanted to target Jason, Gwen refused and helped Jason, Brick, Katie and Rex vote Izzy out, succeeding in doing so. The girls kicked Gwen out of their alliance, but Gwen would soon make a new one with Jason and Diana.

Both of the main alliances would work together to blindside Rex after this. The final 8 alliances would now be: an alliance between San, Courtney and Diana, one between Jason, Gwen and Diana, and one between Katie and Brick.

An auto would cause the San-Courtney-Diana alliance to be down in numbers, as San was automatically eliminated and Courtney now didn't have enough votes with her to save her. With this, Diana depended more on her alliance with the couple.

The longest lasting alliance would be the final three alliance, and they would soon dissolve once they worked together to get Katie out and make it to the final three.
