Rotten Rebecca is a character mentioned in ANDY HATES ROTTEN REBECCA!! (RAGE). While not stated, she is presumed to be Andy's psychotic ex-girlfriend. Little is known about her, however she was mentioned to have tried to stalk Andy, and the judge said that Andy and her couldn't see each other. Little is known about her, but she was revealed to have presumably dated and stalked Andy, making Violette go to court to testify. In one of their fan mail videos, they were asked about her, and William and Violette responded by saying they'd talk more about her in a future video. In WILLIAM ANDY ANDY BEAT EACH OTHER WITH PEPPERONI STICKS!!!, she was briefly mentioned by William, who said Andy was probably saving his pepperoni stick for her.
Despite not being in a video, a lot of people hate her based on conclusions of her. They said that she is even worse than Bill as she likes to stalk Andy and get in trouble with the law. However, sone fans like the sense of mystery she adds to the series, as not much is known about her. Those who are interested in finding out more about her often ask to know more details of her, which Violette said they might discuss in a future video. For now, she is mostly a mystery.
