Dragonfly was with the X-Men at NORAD in Cheyenne Mountain. After she was defeated, she was kidnapped and further mutated by the Stranger, eventually returning to Earth alongside several of his other specimens following a rescue by Quasar and a reality-displaced Squadron Supreme, and occasionally assumed the appearance of a giant dragonfly who could control insects. In this state, she was left mindless and manipulated into doing her sister's bidding.
Dragonfly was the cousin of one of Peter Parker’s fellow photographers at the Daily Bugle. However, he became their assassin, known as the Dragonfly. Their sensei, Madam Qwa, ordered Karsano to kill Meiko to prove his loyalty.
