Rosie Stronghold, Third generation hero, daughter of the Commander and Jetstream, and Will's twin sister. Unlike her brother, she already knows her power, and it's neither super strength nor flying. No, Rosie teleports, and she can also control water, both powers being from her grandparents instead of her parents. Starting Sky High, she becomes immediately drawn to the most feared guy in the entire school- Warren Peace. The only problem? Their dads are arch enemies, as are he and Will.
But fire and water? Opposites definitely attract!
(All rights go to Disney, I only own Rosie.)
