Mother's Milk (character)

Mother's Milk, or simply M.M., is a fictional character appearing in the comic book series The Boys, created by Garth Ennis and Darick Robertson. He is a member of The Boys, a group of CIA-sponsored black ops agents led by Billy Butcher who observe, record, and sometimes liquidate "Supes" (i.e. super-powered individuals who often masquerade as superheroes) artificially created by the mega-conglomerate Vought.

M.M.'s mother was exposed to the superpower-inducing Compound V while she was pregnant, the result of which was her eventually mutating into a Cthulhu-like creature, and him becoming the first naturally-born Supe. To stay alive, Mother's Milk requires continued consumption of his mother's Compound V-enhancing "mother's milk" on a regular basis, leading to him taking the term as a sobriquet and boxing ring name. He later rises to become heavyweight champion of the world following his military career, before being recruited to the Boys after accidentally killing his opponent in the ring, becoming Butcher's second-in-command/best friend over years of missions and befriending Hugh "Wee Hughie" Campbell on his own recruitment. After helping Butcher finally get his revenge on Black Noir, M.M. learns that Butcher plans on killing all Supes and potential Supes (i.e. every person ever exposed to Compound V), including him and his daughter. After confronting Butcher over this (and for having already killed Frenchie, the Female, and M.M's abusive ex-wife), M.M. is killed by Butcher to prevent him from interfering with his plan. M.M.'s mother then gives milk to Hughie, who confronts and kills Butcher.
