Melissa Gold was a troubled runaway who developed a hard edge to her personality, referring to herself as “Mimi”, in order to survive on the streets. She eventually found work as a costumed professional wrestler, taking the stage name Screaming Mimi, and joined the wrestling team known as the Grapplers.
The Grapplers became renowned for their colorful personalities and ringside antics, but the wrestling federation denied them the opportunity to make the amount of money their male counterparts made. Instead, the group agreed to earn supplementary income by performing a covert operation for the Roxxon Oil Company and were given special paraphernalia to assist them in their mission. The mission failed, and the Grapplers were tried and jailed for their misdeeds.
Imprisoned in the Big House, Melissa is one of the few inmates who proved open to rehabilitation, even expressing interest in using her abilities for good. During the Breakout, she escaped the Big House with Mandrill and Vermin, but refused to participate in any violent actions against S.H.I.E.L.D. personell, and surrendered herself immediately to Maria Hill and the Wasp. She remains in S.H.I.E.L.D. custody.
