M.O.D.A.M.

Bursting onto the scene in 1990's Quasar #9 — courtesy of the legendary Mark Gruenwald and artist Mike Manley — M.O.D.A.M. is a Copper Age Marvel creation with a menacing pedigree, operating under the banner of the notorious scientific terror organization A.I.M. Her appearances span titles like Captain America, Force Works, and Quasar, putting her in the orbit of heavy hitters like Captain America and Diamondback, which tells you everything about the caliber of conflict she's built for. Though her catalog footprint is compact, there's something deliciously compelling about a character who debuted with such a distinctive name and such formidable company — a true product of early '90s Marvel ambition.
