Warning! Spoilers for The Boys comic book series below.
In The Boys comic book, Queen Maeve has a secret son named Blarney Cock, who might have the most absurd, messed-up story among his fellow Supes in the series. Not only does Blarney Cock's story involve getting killed and resurrected, but heavily features some of the most depraved acts in the comics - which says something, especially given the outright grossness The Boys often portrayed.
Queen Maeve is The Boys answer to Wonder Woman and one of the least problematic characters on The Seven's superteam roster. In the comics, Queen Maeve shares a brief romance with Homelander but is tricked into being assaulted by Black Noir. She also becomes an alcoholic after Homelander refuses to save a hijacked plane on 9/11. Queen Maeve ultimately stands up to Homelander after he confronted Starlight, which led to her brutal death. Later comics reveal that Maeve had a secret son who was also a superhero, Blarney Cock, who isn't exactly someone she'd be proud of.
Blarney Cock, an Irish Supe who's part of the Teenage Kix superteam, first debuted in The Boys #4. Blarney, who has the powers of flight (and later resurrection) participates in team orgies, takes hard drugs, and is just a terrible person in general. In the series sixth issue, Billy Butcher and his gang attempt to take down the Teenage Kix, with the fight ending with Hughie accidentally killing Blarney by sticking his hand through his chest (powered by Compound-V). As Blarney lays dead on the ground, a hamster crawls out his pants - as it was hiding in his ... backside area.
Later in the series, Blarney Cock would return as a zombie-like version of his past self. He would break into Hughie's apartment and urinate on the floor in an effort to retrieve his hampster. Hughie would snap his neck, killing him again - with his body being lit on fire so that he wouldn't come back again. Much later in the series, it was revealed that Blarney Cock was the son of Queen Maeve and the Legend, who had a secret affair. Whether Maeve kept tabs on Blarney Cock is unknown, as the reveal was sort of thrown-in without any real big purpose or future storylines following up on it.
Blarney Cock was a disgusting, foul Supe who readers would later find out had a connection to Queen Maeve. Perhaps, if Maeve played an active role in his life, he wouldn't have turned out to be such a gross Supe. Their true relationship was never revealed, however. It would be surprising if The Boys' television series adapted Blarney Cock as Queen Maeve's son in his comic form, as he seems like a character who is best to be left on the cutting room floor.
