Loki

Loki is a black bunny adopted by Ennui and is unofficially dubbed by Don as the third member of The Goths.

Total Drama Presents: The Ridonculous Race
In Down and Outback, Ennui uses his ability to attract animals to easily capture ten bunnies for his team. Though he usually dislikes cute animals, he takes a liking towards a black bunny after realizing the destructive capabilities of his species on the Australian environment. He later decides to keep the bunny, giving it a heavy Gothic makeup look, and names it after the Norse god of mischief and chaos, Loki.

Loki is shown to have aggressive features and growls at almost anyone but the Goths as it seems quite fond of the latter. It prefers to cling onto Ennui's shoulders but is sometimes kept inside his shirt. Loki proves to be useful in challenges, as it helps Ennui locate a ring hidden under a pile of snow in Lord of the Ring Toss.

In Got Venom, despite the Ice Dancers attempting to sabotage Crimson and Ennui by getting rid of Loki, it decides to stay with its owners. After "linking" with Ennui, it comes up with a plan to collect a komodo dragon's venom. At the top of a tree, Loki attracts the attention of a komodo dragon and lets it drip its saliva into a bucket, winning the challenge for its owners. In the second challenge, Loki quickly helps the Goths locate their rug and secures their first place win.

In Dude Buggies, Loki jumps into a lion's mouth during the magic challenge. However, Ennui manages to pull it out safely. The magician overseeing the challenge is impressed by this and lets the Goths pass the challenge, allowing them to reach the Chill Zone first.

In El Bunny Supremo, Loki is stolen by the Jacques and Josee, and is hostile towards them during its capture. Upon realizing Loki's disappearance, the Goths subsequently stop performing in the challenge and desperately look for it. It eventually breaks free from Jacques and scares the Ice Dancers' donkeys away as it hops away and rides a donkey back to the Goths. This delay causes the Goths' elimination, which pleases the Ice Dancers, until Loki makes a cut-throat gesture at them, very much to their horror.

Loki is last seen in the season finale, watching the final outcome of the Race with its owners and is also seen during the final group photo.

Trivia

 * Loki's connection to destruction is associated with the concept of rabbits as an invasive species in Australia, where they are not native.
