Scarlett (Kristi Friday) is the main antagonist of Total Drama: Pahkitew Island and one of two villains from her season. Highly intelligent and seemingly polite, Scarlett appeared to be a qualified contestant for Total Drama. She was also the sidekick of self-proclaimed "supervillain" Max, whom she humored in his attempts at proving himself to be an evil supergenius. She also showed small acts of apparent kindness throughout the series, such as comforting Amy when she fakes being heartbroken over her sister calling her out for being a bully to her.
Scarlett revealed her true colors in the 10th episode of the season, "Scarlett Fever", which is that of a mad scientist who is quite wicked. During the episode, Chris revealed to the contestants that the island was really a robotic replica and that their "challenge" for the day was to deactivate the island before it self-destructed. Scarlett and Max managed to find a shortcut to the island's control center, where Scarlett proclaimed that the island was now under her control. When Max dismissed her and referred to her as his "sidekick", Scarlett became angry and made her villainous transformation, taking off her glasses and letting her hair down. After using one of Chris McClean's bear robots to scare Max out of the room, Scarlett contacted the host through the control center monitor and threatened to flee in an escape pod and allow the island to be destroyed with everyone on it unless he handed over the million dollar prize money, which was her true reason for joining the show. When Chris accused her of bluffing, Scarlett proved him wrong by firing tree missiles at the helicopter he was on with Chef Hatchet.
When the other contestants arrived to stop Scarlett, the evil redhead ignored Sky's pleas for mercy and sent more robots (these in the shape of Chris McClean himself) to defeat them. Shawn, however, was able to destroy them all and they used one robot to lure Scarlett out of the control room under the belief that Chris was going through with her order. Sugar tackled the villainess and hogtied her with her own hair while Sky successfully stopped the island's self-destruction process just in time. Scarlett was later eliminated along with Max, who Chris had grown annoyed with. Scarlett and Max were finally fired out of the elimination cannon, with Scarlett begging Chris to eliminate her with anyone but Max.
