Butcher’s Desperate Gamble in ‘The Boys’ Season 5 Episode 7 Just Turned Him Into the Show’s Most Dangerous Villain

‘The Boys’ has always thrived on blurring the line between hero and monster, but the penultimate episode of its final season just shattered that line entirely. In this week’s episode, Billy Butcher’s latest desperate plan to take down Homelander is revealed after the Supe-killing virus is rendered useless against an immortal enemy.

Titled ‘The Frenchman, the Female, and the Man Called Mother’s Milk’, the penultimate episode officially streamed on May 13, 2026, exclusively on Amazon Prime Video. With one episode left before the curtain falls on Eric Kripke’s superhero satire, this chapter arrives as one of the most bruising, emotionally gutting installments the show has ever delivered, and it fundamentally reframes who the real villain of the finale will be.

Butcher’s New Plan Pushes the Anti-Hero to His Absolute Limit

Using uranium and research tied to the Russians’ original experiments on Soldier Boy, Butcher hopes to turn Kimiko into a weapon capable of neutralizing Homelander’s powers. Despite the risks, Kimiko agrees to undergo the procedure, while Frenchie stays by her side throughout the process.

Sister Sage joined hands with Butcher and the gang in the previous episode, and in this installment she was closely working with the group to take down Homelander. The team recreated Soldier Boy’s radiation beam, which can strip any Supe of both their powers and their immortality.

Sister Sage uses an incredibly unstable machine on Kimiko, heavily relying on her regeneration abilities to withstand extreme radiation and alter Compound V. Sadly, this desperate plan spirals out of control rapidly.

In the final minutes of the episode, Kimiko becomes a lab rat for the experiment, locked in a chamber and exposed to extreme radiation for thirty seconds. Her skin starts to burn and she collapses inside the chamber.

Frenchie’s Heartbreaking Sacrifice Costs the Team Everything

Frenchie sacrificed himself to save Kimiko while she recovered. The episode’s theme was all about love and its illogical unpredictability, and as a direct continuation of this theme, his death hit with maximum emotional weight.

Frenchie decides to stay behind after hiding Kimiko and Sister Sage inside a zinc-lined space so Homelander cannot sense them. With nobody else around, he becomes the only person standing between Homelander and the others. He tries bluffing Homelander by claiming the team has successfully recreated Soldier Boy’s power, then throws a few insults at him instead of begging for mercy.

When the villain questioned Frenchie about turning Kimiko into a Supe with Soldier Boy’s blast powers, the chemist confirmed that the plan worked. Soaked with uranium, Homelander flew off before the power could be used against him, but the tragedy struck when Frenchie was also irradiated, leading to radiation sickness and his slow death in Kimiko’s arms.

Instead of going out during a huge action scene, Frenchie dies protecting the people he loves most, which feels entirely true to his character. Season 5 has already delivered major deaths, but losing a core group member carries a different weight entirely.

Homelander’s Immortal Grip on the Oval Office Begins a New Nightmare

Homelander was seen basking in his new immortal reign, smiling with his legs up on the White House desk. With a little squeeze, he killed the President after Ashley had revealed the man’s true inner thoughts about him, and this was just the first indication that the newly self-proclaimed God has a zero-tolerance policy toward those who refuse to worship him.

Oh Father had been executing a marketing campaign to introduce Homelander as a deity within a New World Order, complete with a musical number and religious-themed content. Multiple words linked to Jesus were censored across the world during this episode on Prime Video.

Using psychic Supes’ abilities to discern the faithful from the rest, people who failed the test were immediately eradicated by other Supes, despite Oh Father pleading that he could convert them.

Gen V characters Marie Moreau and Jordan Li finally appear in the episode, after showrunner Eric Kripke had previously teased that the ‘Gen V’ kids would show up before the season ended. Many fans have begun speculating on the significance of Marie’s hemokinesis powers, which could potentially remove the V1 component from Homelander’s bloodstream and make him mortal again.

Butcher Goes Rogue and Sets Up a Three-Way War for the Finale

Billy Butcher has officially crossed the point of no return in this episode, abandoning his team to execute a genocidal endgame with the Supe-virus. By fully surrendering to the Joe Kessler hallucination, Butcher has transitioned from the show’s anti-hero to its secondary antagonist, setting up a three-way war for the series finale.

The show is positioning both Butcher and Homelander as villains heading into the finale. Homelander represents fascist tyranny while Butcher represents nihilistic genocide, and the remaining Boys are trapped between them.

The most heartbreaking beat of the episode involves Ryan’s realization that neither his father nor his mentor actually has his best interests at heart, setting him up as the wild card for the finale as the only person powerful enough to stop Homelander, but one who no longer has a clear reason to save the world Butcher is trying to poison.

The ‘The Boys’ series finale, titled ‘Blood and Bone’, is set for May 20, 2026, on Prime Video. With Frenchie gone, Homelander playing God, and Butcher now a genuine threat to every Supe on Earth including his own allies, the endgame has arrived in the most devastating shape imaginable. Now that Butcher has fully become a monster in his own right, is there any version of this finale where he can be considered anything other than the final villain Hughie has to stop?
