Megan Gwynn is a Welsh teenager who attends the Xavier Institute for mutants. Her mutant powers activated after an accident with her bicycle in the road nearly hitting car. She got a scholarship to attend the Xavier Institute of Higher Learning. After enrolling at the Institute, Gwynn was assigned to the Paragons training squad under the tutelage of former New Mutant, Rahne Sinclair, Wolfsbane. When it was revealed that Sinclair had been in a romantic relationship with a student, Josh Foley, she left the school, and was replaced by her former teammate, Magma.
Gwynn has proven herself to be an amiable and cheerful student, and she fit in well with her squad. Following the events of House of M, almost all of the Institute's students were de-powered, leading to the dissolution of the school's training squads. Gwynn is one of only 27 student, along with her fellow former Paragons, Trance, Wolf Cub, and Match, to have retained her mutant abilities.
