Hughie Campbell / Wee Hughie

Hugh Campbell often called by his nicknamed "Wee Hughie," Hughie first experiences the world of superhumans firsthand when his girlfriend was accidentally killed by 'A-Train', during a fight in which the latter was traveling faster than the speed of sound. Due to this experience, Butcher recruits to take Mallory's vacated spot on the Boys, and would later inject him with Compound V, without Hughie's permission.

Hughie grew up in rural Scotland, an adopted child. He had a rather bizarre childhood, including a period of trauma from exposure to a giant tapeworm and a childhood friend called Det with an unnaturally powerful stench. With his childhood friends, he played at being a boy detective; they also once threw stones at a dog, only for Hughie to get upset when one of his throws hit it's mark, and out of guilt would spend the evening taking the injured dog back to its home. As an adult, he'd leave for Glasgow. His relationship with his parents and childhood friends has him being irritated by how they sometimes treat him, while outside viewers (Starlight/Annie and Mallory) have pointed out he's lucky to have them.

Hughie is still an innocent to the Boys' world, and at times this has resulted in him becoming hesitant in his actions. Shortly after his first combat experience which resulted in his accidental killing of Blarney Cock, he became extremely worried about repeating the action, which nearly resulted in the escape of Swingwing in a subsequent operation. He also would become gradually disgusted with Butcher's easy willingness to torture their enemies and the others' lack of caring about it. As the series progressed, and the bloodshed gradually increased, Hughie would also grow angry with Butcher's dismissal of the constant violence ("big boys' rules") used in their operations.

Despite his distaste with the antics he's observed while a member of the Boys, he has developed a pair of close relationships within the community. He has made friends with Russian hero Vas and, unknowingly, the super-heroine Starlight, the latter with whom he developed a romantic relationship. Despite an early embarrassing accident where he had oral sex with her when she was menstruating, their relationship kept on going - causing Butcher to wonder, upon his discovery of the relationship, if Hughie was working for Vought-American. After becoming assured that he wasn't, Butcher would deliberately break the relationship up by setting Hughie up to see footage of Starlight's "induction" into the Seven. Unable to cope with the knowledge, he angrily laid into her and broke off the relationship, only to suffer guilt over his verbal abuse with her; the two reconciled and got back together. He finally comes clean to her in #55 about his work, and begs her to leave and hide so she's not killed when events eventually escalate to their conclusion.

Hughie is viewed as a genuinely nice guy by most people who know him, and he has several times risked himself to try and help people who were vulnerable or victimised: his rage over Swingwing callously killing a young man in #10, his attempts to save G-Wiz, and trying to fight the horrifically powerful Malchemical to defend Superduper in #43. Butcher was confused and irritated by the latter incidents, as he had advised him several times that the superhuman population largely does not care about normal people. The "Highland Laddie" miniseries had Hughie feeling discontent that, unlike Butcher, he isn't a hard man, but he seems incapable of being one. Annie would later tell him that he is just too nice because of his upbringing, but that this doesn't make him any less of a man.

In Herogasm #3, he was sexually assaulted by Black Noir. While he was left shocked and sickened over it, he did not say what happened to the other Boys, until much later in time. However, due to the fact the confession was timed right after their Flat Iron office was attacked, it was largely met with indifference.

During the events of the attempted coup of the US Government by the Homelander, Butcher captures A-Train with the hopes of getting Hughie to finally understand what it means to be one of The Boys. He makes Hughie listen to recorded conversations of them discussing Robin, hoping to convince him to murder A-Train. Hughie can't bring himself to kill the captured man, so Butcher starts playing further conversations of the Seven - tactic Hughie sees through and refuses to be provoked by, demanding Butcher to stop. However, when the tape reaches the Seven's plan to hire Starlight so they can degrade her, Hughie finally snaps and kicks A-Train's head off.[1]

In the aftermath of the fight with The Seven, Butcher tells The Boys that Hughie will be second in command, which infuriates his teammates, due to Butcher's revelation that Hughie sought out the position - a deliberate act by Butcher. Annie also leaves him, still unable to reconcile Hughie's job and his past attempts to conceal it. During the turmoil, during which the Boys are also disbanded, Hughie gets a text from Vas, but didn't understand what it meaning at first. After a visit to the Legend, during which he learns of Vas' death, he is given a clue by the Legend, who also advises him to see Kessler for help in remaining in the United States. The conversation with Kessler goes badly, in which Hughie's attempts to talk sensibly with the CIA man are rejected, and progress is only made after Hughie threatens him in a similar manner to Butcher. Hughie also decodes Vas' message as an email address, which results in an automatic reply containing evidence that Butcher has been obtaining modified Compound V that can be used to kill superhumans - and that he has killed Vas. It becomes clear that Butcher has been trying to get the team out of the way so he can carry out a mass murder of superhumans.

He intentionally resembles the British actor and writer Simon Pegg.

Ennis has said that Hughie has a "total inability to learn from his mistakes and change his ways [which] will eventually stand him in good stead... No doubt Hughie’s tendency to mope and turn inwards is a source of frustration to many readers, all used to comic heroes who learn from experience and develop into fully-rounded characters ready to handle anything. In my experience this is like no one who’s ever existed in real life; even the most capable people either maintain or eventually return to their essential flaws. I doubt any twenty-something lad unused to trauma and violence could simply absorb it straightaway, and if he did become hardened or inured it would be as a different, less sensitive person. In other words, Hughie’s bizarre triumph is that he remains Hughie."
