Sherry's appearance is the one which varied the most throughout the games, with her most common traits being a more human-like face and long pink hair. In the first game she wears a green dress and is about as tall as Sparkster himself. In the second game she is given a visual overhaul, appearing much taller and wearing a light blue dress.
In Rocket Knight, Sherry only appears briefly during the ending sequence, with a somewhat older appearance and less human-like face.
Despite being a princess, Sherry is a very educate and kind person, if only a bit naive. She eventually becomes Sparkster's girlfriend, though they eventually break up when Sparkster retires from his Rocket Knight position and leaves Zephyrus. Though she is left heartbroken, she still seems to care for him.
Being the princess of Zephyrus, Sherry is the inheritor to the "Key to the Seal", needed to reactivate the sealed Pig Star. Because of this the Emperor Devligus Devotindos orders her kidnapping and takes her to his castle in the Devotindos Empire. Once she unseals the Pig Star she is left behind by Devligus, being rescued by Sparkster and using her magical powers to allow Sparkster to fly in space. Once the Pig Star is destroyed Sparkster takes her back to Zephyrus.
