Marvin T. "Mother's" Milk is one of the main characters in the Amazon series The Boys and an original member of black ops group The Boys.

Mother’s Milk left Butcher and The Boys for a reason. Now he’s got a good job, where he’s making a difference in the lives of wayward kids, and he’s made a happy home with the love of his life, Monique. But Butcher insists he can’t fight the war on Supes without M.M.’s detail-obsessed, methodical mind. And if M.M. is being honest with himself, he misses the action. But he worries that Butcher’s win-at-all-cost pursuit of Homelander will put lives at risk – especially the people M.M. cares about.
