Valkyrie

Valerie Kellum was an archeologist who discovered what she first took for an ancient spear. A more careful examination led to the realization that the spear had a technological component. She traveled around Europe looking for ideas about its origin and ended up in a local Crey facility. When a Crey security team tried to take the weapon from her it activated and injected Valerie with advanced nanites that transformed her into Valkyrie, a extraordinary warrior with a completely different personality. She broke free and traveled to Paragon City where Positron is helping her come to terms with her new identity.
