Based on the animated television series, Atomic Betty for Game Boy Advance is a side-scrolling platform game that pits the intergalactic pre-teen and her friends against Maximus I.Q. and his evil associates. Playable characters include Betty, Sparky, X-5, Noah, and Paloma, each with different special abilities. Players can choose the three characters they think will be best suited for a particular mission, and then switch between them on the fly as they play through the level.
