Spotlight On: Magenta (Frances Kane Isn't Herself Today) (Volume 1, Issue #17)
When Frances Kane struggles with her dual identity as the super heroine Magenta, she turns to S.T.A.R. Lab doctor Alysia Demalis, who offers to help her using a new experimental therapy. The therapy is supposed to split Frances and Magenta into separate personalities as a first step towards resolving the psychological issues of both. Instead, Dr. Demalis uses it to turn Frances into a brainwashed sleeper assassin. When Thunder and Lightning pose a threat to the doctor's plans, she triggers "Magenta" and programs her to kill the two superheroes.
