Mother's Milk, or simply M.M., is a fictional character and antihero appearing in the comic book series The Boys, created by Garth Ennis and Darick Robertson.

Born Baron Wallis,[1] 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.

Unlike the comic series, Marvin T. "Mother's" Milk, primarily known as M.M., is depicted as a regular human (though still a military veteran) with a dislike of Vought and its Supes resulting from a car crash caused by Soldier Boy in M.M.

's youth, which killed his mother, uncle, and grandfather, and led to his father working himself to death as a lawyer unsuccessfully attempting to sue Vought.

A large, highly patient and methodical African-American man, Mother's Milk first appears in issue #2.

Taught by his father to check every possible angle and means of attack, can be somewhat particular (getting annoyed whenever anyone doesn't put a drink coaster under their glasses).

His mother worked in a factory that had previously been a Vought-American (VA) laboratory, and hadn't been sanitized afterwards, leading to her being contaminated with Compound V. As a result, his brother Michael was born with severe mental disability and he himself was born needing regular doses of his mother's breast milk to survive, the true origin of his nickname.

[3] His father worked tirelessly to sue VA over his children's special needs and eventually succeeded, but the experience took a large mental and physical toll on him.

would go on to perform community work and raise his increasingly rebellious daughter, now a teenager (and as a result of Compound V, matured early – although she appears 16–17, she's only 12 chronologically); Janine shows M.M.

He is one of the few people who receives any consistent level of civility (at least to his face) from the pathologically rude Butcher, who thinks very highly of him.

He is also the only member of the Boys (other than Hughie, the new recruit) who thinks that at least a few superheroes might be acting out of genuine altruism (as mentioned in issue #6).

[7] In The Bloody Doors Off, Mother's Milk discovers that his abusive ex-wife and daughter were in a pornographic film together.

Mother's Milk finished having a meeting with The Boys on stopping Butcher from using a weaponized version of the "V" compound on the rest of the Supes and the innocents that were affected.

Butcher walks in on Mother's Milk, questioning why he wasn't trying to fix his issues with his daughter, thinking that would get him out of the picture for good.

's mother after his death, discovering she has grown into an enormous Cthulhu-like blob creature; her breasts have elongated to tentacles (explaining why M.M.

displays nausea when snakes are described by a nature show in an earlier issue) and she seems only able to say "MY BOY..." when she spots Hughie, apparently not realizing he is not her son.

When she grabs him with one tentacle and presents another with a distended nipple at the end, Hughie consents to drink, possibly hoping the milk will strengthen him (he is unable to keep it down, however), and manages to stop Butcher from enacting his plan, killing him before toasting to the memory of M.M.

Hughie reads through the diary which delves into Butcher's moral justifications and darker work with Boys (including M.M.)

prior to Hughie's own recruitment, including when they had tortured and cut out the tongue of a child (a parody of Billy Batson / Captain Marvel) to prevent them from ever being able to return to their Supe form.

was a child, killing his grandfather, which Vought had then covered up by claiming Soldier Boy's actions were caused by apprehending car thieves.

[17][18] Mother's Milk is a physically fit former boxer and United States Army Ranger later employed by the CIA, one of the only naturally-born Supes, resulting from his mother being exposed to large quantities of the enhancement drug Compound V,[19][20] granting him superhuman levels of strength and durability which allow him to casually injure and kill regular humans as well as "Supe" superhumans.

[22] In the Amazon Prime Video streaming television adaptation, Mother's Milk is instead depicted as a regular human, opposed to Butcher's use of the temporary superpower-inducing V-24 in the third season.
