Gwen (voiced sa pamamagitan ng Megen Fahlenblock) is labled as "goth girl" although "misunderstood" is madami acurate. She auditioned for TDI on a dare, thinking she'd never get on, but when she did, she decided she could use the money to help her mom or go to college. Her mga kaibigan on the island are Trent (her pag-ibig interest), Leshawna (her BFF), Bridgette (a good friend), Duncan, Owen, and Cody (whom she nakakita as a annoying little brother). She came in segundo place, losing to Owen on "The Very Last Episode, Really."
Catchphrase: whatever
She will be on Total Drama Action.
