The Boys S5E5 Guide: Supernatural Reunion & Seth Rogen Cameo
The Boys Season 5 Episode 5 features a massive Supernatural reunion and a brutal Seth Rogen cameo. Explore the Bombsight lore and every Easter egg here!

The stakes have never been higher as The Boys Season 5 Episode 5, titled "One-Shots," delivers a masterclass in meta-commentary, visceral gore, and the long-awaited "Supernatural" reunion that fans have demanded for years. As the series hurtles toward its final conclusion, showrunner Eric Kripke has transformed this installment into a star-studded bloodbath that serves as both a political allegory and a "stealth sequel" to the 2013 comedy classic This Is the End.

In The Boys Season 5 Episode 5, the hunt for V1—a substance rumored to grant Homelander true immortality—takes Soldier Boy and the Vought leader to Hollywood. What follows is a chaotic collision of television's most beloved actors and a brutal culling of the A-list elite. From the introduction of Mister Marathon to the satirical "Homelander Bible," this episode fundamentally shifts the power dynamics of the Vought universe.

The Supernatural Reunion: Sam, Dean, and Castiel Together Again

For fans of the long-running CW series Supernatural, The Boys Season 5 Episode 5 is the ultimate payoff. Eric Kripke has finally brought together the "Team Free Will" trio: Jensen Ackles (Soldier Boy), Jared Padalecki (Mister Marathon), and Misha Collins (Malchemical). This marks a total of four major Supernatural alumni appearing in the series, following Jeffrey Dean Morgan’s introduction in Season 4.

Jared Padalecki makes his debut as Mister Marathon, the original speedster of The Seven who was unceremoniously replaced by A-Train years prior. Unlike his comic book counterpart, who was a white, clean-cut hero, the TV version of Mister Marathon is a washed-up, bitter Hollywood socialite. He is joined by Misha Collins as Malchemical, a supe with the ability to emit a potent knockout gas from his mouth.

The reunion takes a dark turn when Malchemical, at the urging of Marathon, uses his gas to incapacitate Homelander. This triggers a violent confrontation where Soldier Boy—in a moment of meta-irony—chokes out Malchemical. For fans, seeing "Dean" attack "Castiel" was a shocking subversion of their brotherly bond on Supernatural. The sequence concludes with Homelander awakening and brutally stomping Mister Marathon’s head, effectively ending Padalecki's brief but memorable stint on the show.

Who are the cameos in The Boys Season 5 Episode 5?

  • Seth Rogen: Playing himself as a Hollywood elite and Starlight supporter.
  • Jared Padalecki: Starring as the retired speedster Mister Marathon.
  • Misha Collins: Appearing as the gas-emitting supe Malchemical.
  • Christopher Mintz-Plasse, Kumail Nanjiani, and Will Forte: Playing fictionalized, fearful versions of themselves.
  • Celebrities in 'Freedom Camps': Mentioned names include Meryl Streep, Benedict Cumberbatch, Joaquin Phoenix, and Macaulay Culkin.

Seth Rogen's Brutal Cameo and the 'This Is the End' Connection

Seth Rogen, who serves as an Executive Producer and was instrumental in bringing The Boys to television, appears as himself in a scene that mirrors his 2013 film This Is the End. In that movie, celebrities played exaggerated versions of themselves during the apocalypse; here, they attempt to survive the "Homelander apocalypse."

Rogen is joined by Christopher Mintz-Plasse, Kumail Nanjiani, and Will Forte for a high-stakes poker game at Mister Marathon's mansion. The meta-humor peaks with a Superbad reunion between Rogen and Mintz-Plasse, featuring a jab at their real-life co-star Michael Cera. The actors discuss the "Freedom Camps"—Vought-run internment centers for celebrities who opposed Homelander’s regime.

The list of celebrities currently held in Freedom Camps or executed includes:

  • Aziz Ansari, Macaulay Culkin, and Joaquin Phoenix (Detained)
  • Meryl Streep, Benedict Cumberbatch, and Benedict Wong (Detained)
  • Kiefer Sutherland (Detained)
  • Bill Hader (Confirmed Executed)
  • Channing Tatum and Post Malone (Next on the hit list)

The scene ends in typical The Boys fashion: Soldier Boy uses the A-listers as human shields in a fight against Mister Marathon. Rogen suffers the most graphic exit, being literally torn in half by the speedster before Marathon himself is executed by Homelander.

Who is Bombsight? The Search for V1 Explained

A major plot point in The Boys Season 5 Episode 5 is the search for Bombsight. In the original comic book lore, Bombsight was a member of the Payback team during World War II, serving as a predecessor to supes like Stormfront. He was known for his durability and the ability to generate explosive force.

In the television adaptation, Bombsight is framed as the keeper of the V1 formula. While Compound V creates supes, V1 is whispered to be a refined version that could grant Homelander permanent invulnerability and halt his aging process. Stan Edgar provided the initial lead, but it was Soldier Boy's interrogation of Mister Marathon that confirmed Bombsight is still alive and hiding. The quest for V1 sets the stage for a final showdown, as Billy Butcher and the Boys are also racing to find Bombsight to prevent Homelander from becoming a literal, unkillable god.

Homelander's New Religion: The 'Brand New American Testament'

The episode’s sharpest satirical teeth are reserved for Firecracker and her rebranding of Vought. She unveils a plan to transition Homelander from a "prophet" to a "god" through the Democratic Church of America. This subplot introduces the "Brand New American Testament," a Bible supplement written by an AI trained on Pat Robertson.

The Pat Robertson AI satire serves as a scathing critique of the intersection between celebrity worship and religious nationalism. By using AI to generate scripture, Vought effectively removes the "meekness" of traditional Christianity, replacing it with a doctrine of strength and supe-supremacy. This religious upheaval is designed by Sister Sage to trigger civil unrest, allowing Vought to justify the "Freedom Camps" and the recall of all supes from overseas to police American metros.

Mister Marathon: Comics vs. TV Comparison

Long-term fans of the comics will notice significant changes to Mister Marathon. In the source material, he was a member of the original Seven who died during the failed 9/11 plane rescue—the same event where Homelander famously abandoned the passengers. The TV show reimagines him as a survivor who was simply "aged out" and replaced by A-Train.

This change allows the show to explore the "washed-up celebrity" trope. While the comic version was a tragic figure of Vought's early incompetence, the TV version (played by Padalecki) is a sycophant who tries to play both sides, eventually paying the ultimate price for his lack of conviction.

Key Takeaways from The Boys Season 5 Episode 5

  • The Supernatural Reunion: Jensen Ackles, Jared Padalecki, and Misha Collins shared the screen for a violent, meta-filled sequence.
  • The Meta-Culling: Seth Rogen, Christopher Mintz-Plasse, and others played themselves, with Rogen meeting a gruesome end.
  • The Homelander Bible: Vought is using AI-generated scripture (based on Pat Robertson) to deify Homelander.
  • V1 and Bombsight: The race is on for the V1 formula, which could make Homelander immortal.
  • Malchemical's Powers: While he uses gas in the show, his comic counterpart was an elemental shapeshifter; his TV fate remains a choke-hold away from death.

Conclusion: The Beginning of the End

The Boys Season 5 Episode 5 successfully balances its "One-Shot" vignettes with a forward-moving narrative that places Homelander on the precipice of godhood. The episode addresses the "meta-fatigue" of celebrity cameos by literally killing them off, signaling that the time for jokes is over. As we look toward the final episodes, the question remains: Can Bombsight be found before Homelander secures the V1 formula? With Sister Sage manipulating the shadows and Black Noir seeking revenge on The Deep, the world of Vought is a powder keg waiting for a spark.
