- Quick Answer: While Homelander remains a threat, Season 5, Episode 4 highlights Butcher’s descent into villainy, mirroring his dark comic book counterpart and alienating his former allies.
The Boys Season 5 is expected to see the defeat of Homelander, but it may also be setting up Butcher as the series’ final villain, especially after the events of Episode 4, “King of Hell.”
Homelander has long been established as the main antagonist of the series, but recent developments suggest Butcher is gradually being shaped into the ultimate threat.
With the show drawing inspiration from the comic book series of the same name by Garth Ennis and Darick Robertson, which teases a dark ending, will Butcher ultimately be revealed as the final villain in The Boys Season 5?
What Happened in The Boys Season 5, Episode 4?
Warning: Major Spoilers Ahead. Read with Caution.
The Boys Season 5, Episode 4 follows the main characters on a journey to Fort Harmony in search of the V1 serum, which Homelander is also determined to obtain.
However, a Supe named Bombsight reaches it first. With the volatile power of another V1-enhanced Supe, Quinn, tensions escalate and ultimately erupt into a battle involving the main group.
While several characters, including Hughie and Kimiko, have shown darker sides, Butcher’s behavior has changed most dramatically.
He has become the most volatile member of the team, and his gradual transformation each season increasingly mirrors Homelander’s own descent.
In fact, the Season 4 finale already hinted at him embracing his worst instincts over his humanity, pushing him closer to villain territory.
So does this mean Butcher will ultimately become The Boys Season 5’s final threat?
Will Butcher Become The Boys Season 5 Villain?
Ever since The Boys began, Butcher has been driven by a singular mission: to destroy all Supes, especially Homelander, with whom he shares a deeply personal obsession.
This hatred has steadily pushed him further into his worst qualities, which become even more evident in Season 5, Episode 4.
In the episode, Butcher and MM discuss a plan to destroy V1 instead of using it to save Starlight and Kimiko.
Hughie overhears their conversation and calls Butcher out, telling him his human side is “dead” and labeling him a “monster.”
“Maybe I like it better this way,” Butcher replies.
Unmoved, Hughie goes further, telling him he is “as bad as Homelander, maybe worse,” showing how far Butcher has fallen.
The situation escalates when Butcher attacks Hughie, revealing just how unstable he has become and proving the claim that he may be the villain no one saw coming.
If the hit Prime Video series continues in this direction, it could be leaning toward a more comic-accurate, darker ending.
As everything collapses, Butcher’s crusade leads not only to the downfall of Supes, but also the destruction of his own team.
New episodes of The Boys Season 5 drop every Wednesday on Prime Video.
