Mike

Mike was a camper on Total Drama: Revenge of the Island, as a member of the Mutant Maggots. He returned as a contestant for Total Drama All-Stars, as a member of the Heroic Hamsters, and was one of the finalists of the season. Under the control of his evil alternate personality, Mal he was also the main antagonist of the season.

Personality
Mike is a nice, well-meaning pup. However, he isn't himself a lot of the time, as he suffers from Multiple Personality Disorder. This causes him to involuntarily switch to a different person in certain situations, afterwards with no memory to what has happened. According to Mike himself, his condition has caused him much strife in the past. This contributes to him refusing to tell the other contestants about it at first. He instead chooses to be known as an overly dedicated actor/comedian. However, in many instances he finds his claims falling apart. This is especially so when dealing with his crush, Eve. He appears to be at peace with it by Total Drama All-Stars, not even hesitant to announce when he is planning on switching.

TDAS Episode 13:The Final Wreck-ening shows that Mike actually deeply cares for his alters despite finding them troublesome, often unpredictable behavior, he is far from elated at the idea of getting rid of them. Mike's own demeanor is kind, cheerful, and upbeat, but he is also awkward, hesitant, and secretive. He will not admit to things unless directly confronted, but even then he is reluctant to do so. He loves action movies and sports, particularly ultimate kickboxing. His biography hints that he may volunteer to help other young people, and develops positive relationships with them. Mike is extremely protective of Eve and earns a reputation as not being harmful to anything or anyone. He tends to care about people even at the risk of losing the game. As a result of his kindness, the others refuse to believe he is of any threat when certain campers warn of the danger amongst them.
