Melody is Soos' girlfriend, who, goes on their first date with him in season 2 "Soos and the Real Girl". She's shown to be cheerful, with an interest in childish things (e.g animatronic pizza places, small kiddie rides, etc). She meets Soos when she finds him riding a small train in the Gravity Falls mall, before asking if he would like to go on a date later at "Hoo-Ha Owl's Pizzamatronic Jamboree".

She becomes a victim of Giffany's violence and constant need for Soos, being attacked by her on their date.
