Alyssa is one of the babysitters that took Vicky captive when they wittnessed Timmy (the twerp) saving her life.
Alyssa looks slightly younger than Vicky. She wears red framed glasses, a white headband, and a red dress. She has curly red hair. She speaks with a valley girl accent and her voice sounds exactly the same as the other B.R.A.T.s.
The B.R.A.T.s took fellow member Vicky captive when she was rescued by Timmy from a life threatening incident. They considered this an act of weakness and expelled Vicky from their group. During the meeting, their leader Lauren Ledergerber was interrupted by her mother, so she told Alyssa the next meeting would be at her house to which Alyssa replied, "Totally." Later on, the B.R.A.T.s watch Vicky flip out on Timmy and decide she is "B.R.A.T. worthy material" again, but Vicky turns her anger on them and becomes the new leader of B.R.A.T., Alyssa admits that Vicky was always her hero.
