Karl Urban stars as Billy Butcher, leader of the Boys.

Urban, who’s from New Zealand, puts on a cockney accent for his portrayal of Butcher, who’s British. Butcher also has a loyal bulldog named Terror who, in the comics, follows him around almost everywhere.

Both characters are similar in appearance, but Urban’s version has facial hair.

Jack Quaid stars as the most unlikely and reluctant member of the Boys, Hughie Campbell.

In the comics, Hughie is from Scotland. In the show, he’s an American who works as an electronics salesman before Butcher recruits him for his rag-tag vigilante group.

Quaid’s Hughie is clean-shaven and had more hair than his comic-book counterpart.

Both versions of the character often feel guilty about their immoral actions and decisions made as part of their work in the Boys.

The Seven’s patriotic leader, Homelander, is portrayed by New Zealand native Antony Starr.

Starr’s “Boys” costume takes plenty of inspiration from his comic-book character, from the gold eagles on the shoulders to the striped cape that emulates the American flag.

Homelander’s psychopathic nature is touched on in the comics, but it’s amped up to an alarming rate in the TV series.

Erin Moriarty portrays Annie January/Starlight, a supe who genuinely wants to do good in the world.

Starlight can absorb electricity and emit energy blasts from her hands.

Just like her comic-book character, Moriarty’s version of Starlight hails from Des Moines, Iowa, where she was part of the supe group known as Young Americans.

In the show and the comic books, Vought forces Starlight to swap her caped costume for a more revealing bodysuit with a plunging neckline.

The Deep from the comics looks significantly different from the supe played by Chace Crawford.

In the comics, you can barely see The Deep’s face because of the antique diving helmet that he wears. In the show, Crawford’s green costume is slim-fitting and omits the headgear and large cape from the comics.

The Deep also has a more substantial role in “The Boys,” whereas he’s a less active and relevant character in the source material.

Dominique McElligott’s version of Queen Maeve looks significantly different.

In the comics, Queen Maeve is blonde and often seen with a martini in her hand. In the show, she has reddish-brown hair.

Both versions of the supe wear armored costumes, but the colors are different. In the source material, her outfit is purple and silver. In the series, it’s burgundy and silver.

Jessie T. Usher plays The Seven’s self-absorbed speedster, A-Train.

In the show as well as the comics, A-Train was part of the young supe group called Teenage Kix before joining The Seven.

In the source material, he’s a much more inexperienced supe and mainly interacts with fellow Seven member Jack From Jupiter.

The Seven’s most enigmatic member, Black Noir, is portrayed by Nathan Mitchell in the TV show adaptation.

The character doesn’t speak, but he’s stealthy and skilled with knives.

Laz Alonso stars as Mother’s Milk, the most level-headed member of the Boys.

In the show and the comics, Mother’s Milk is cool under pressure and pragmatic. He’s also extremely meticulous and values cleanliness.

Frenchie, the Boys’ tech-savvy member, is portrayed by Tomer Capone.

In the series and the source material, Frenchie’s dialogue is a mix of French and English. Frenchie’s signature accessory is the goggles, which he also wears sometimes in the show.

Karen Fukuhara plays the only female member of The Boys, Kimiko Miyashiro.

In the comics and the show, she’s referred to as The Female. Season two of “The Boys,” revealed her name and more about her origin.

She and Frenchie have a similar dynamic, with him showing empathy and compassion despite her ability to brutally murder people.

Claudia Doumit plays Victoria Neuman in “The Boys,” a gender-swapped version of Vic the Veep from the comics.

In the source material, Vic is a pro-supe Vice President of the US. He’s unintelligent and can’t seem to speak past a third-grade level.

In the Prime Video show, she’s secretly a Congresswoman who denounces supe-terrorists. In the season two finale, Victoria is revealed to be a supe who was orchestrating the mysterious head-poppings.

Jensen Ackles will make his debut as Soldier Boy in season three.

Ackles’ green-and-gold costume is significantly different from his comic-book counterpart, who has a blue outfit with stars and red armbands. Both versions of Soldier Boy are armed with a gold shield.

In the comics, Soldier Boy is part of a group called Payback, but longs to be part of The Seven.
