Margaret is a character from "Regular Show" and is Mordecai's love interest on the show. She is a 22 year old robin with a curved hairstyle and usually wears yellow shirts and jeans when she's not working at the coffee shop in which she wears a light yellow dress. She is voiced by Janie Haddad.
During the first seasons of Regular Show, she had gone through a bunch of ex-boyfriends before she decided to settle down to Mordecai. During the rest of the series, she has developed a crush on Mordecai as he always had one on her. Margaret hardly gets mad at the two heroes. In "Steak me Amadeus", she attends a college which was her dream college, which pressures her from becoming Mordecai's girlfriend, even when the two have become an official couple.
In the MCF stories, she transfers from her college to Cartoon Town's college to get close to Mordecai and is his girlfriend. She makes a debut in "MCF: The Song of Circe" where she has a break from college to meet Mordecai and Rigby's new bosses the MCF. She gets jealous of Circe when she arrives searching for a boyfriend, but knows Mordecai would never dump her for Circe and teams up with Sylvia and the MCF to get him, Rigby and Wander off of Aeaea(Circe's island).
