Barbie is the main protagonist of Barbie Video Game Hero. She is teleported into her tablet when she accepts Cutie's request to beta test his game in order to defeat a virus infecting it. She was chosen to save the game world, due to her high scores in gaming. Her favorite video game is Just Dance, a real-life dancing game series.

Video Game form
- When Barbie is in the game, she is an anime character with extremely long pigtails with a pink bang, and a blue smiling heart that floats above her head. Her outfit consists of:
- A blue shorts leotard with digital square and heart patterns that are more visible in the dark; with pink as its secondary color, along with yellow hearts and a pink heart brooch.

- The base color of the skirt is pink in Levels 2 and 3.
