*Jennifer Ann "Jen" Masterson is one of the main characters of 6teen. She is Jonsey's stepsister because of her mom and his dad remarried. Jen is introduced in series as a responsible individual, born into a family in the shadow of her more glamorous and popular older sister, Courtney, and the prospect of taking on additional siblings. Some time before the series started after Christmas, her parents get divorced and Jen takes it harshly. She and Caitlin are the only ones in the group to never get fired. Jen's the only one in the group to have been continuously employed since the first episode (she hasn't changed jobs since getting her job at the Penalty Box). She is the tallest female of the group. Jen is a fan of the popular boy band DawgToy. Jen is highly allergic to mushrooms, eating them results in her becoming violently gassy and suffering from diarrhea. Jen's voice actor, Megan Fahlenbock, has also voiced Gwen from the Total Drama Series and Sam McCloud, one of the main characters' sisters, from Stoked. She and Gwen are very different, even though they share the same voice actor. Jen shares many similarities with Courtney from the Total Drama series. They both are "Type A" students and are generally very ambitious and competitive. However, Jen's a lot nicer than Courtney, who became meaner over the course of the Total Drama series. Coincidentally, Jen's older sister is named Courtney. Jen lives with Jonesy after Jonesy's dad and Jen's mom gets married. Jen is Irish Canadian. Jen's counterpart is Emma from Stoked, but Emma's got more of a laid-back Type B-personality

Hair: Auburn (some viewers perceive it as brown). Eyes: Blue (sometimes identified as light purple/violet). Build: Tallest female in the main group. Ethnicity: Irish-Canadian. Casual Outfit: Azure hoodie, white skirt with an indigo stripe, and white sneakers. *
