As a main antagonist of season 2, Stormfront is an avowed neo-Nazi and match made in hell for Homelander. This ruthless role, played by Aya Cash, is the antithesis of Cash’s stage role in Giant on Broadway and in London, as a Jewish American publisher who confronts Roald Dahl (played by John Lithgow) on his antisemitic writings. She was up for a 2026 Tony Award nomination for her performance.

Cash has also appeared off Broadway in various productions, starting with The Pain and the Itch at Playwrights Horizons.

After playing a Marvel superhero on The Eternals, Kumail Nanjiani also appears in The Boys's “Imagine” parody and returns to season 5 to be among another ill-fated celebrity circle.

Those who only know Ethan Slater as the titular square sponge in the SpongeBob SquarePants musical or Boq in the Wicked movies might be shocked to see him as villain Dr. Thomas R. Godolkin in Gen V. For theatre fans who know him as Lee Harvey Oswald in the Classic Stage Company’s 2022 revival of Assassins, it wouldn't be surprising. Slater also makes a cameo in The Boys season 5 and is slated to appear in Vought Rising.

She will reportedly reprise her performance in New York in spring 2027.

In a fitting commentary on child actors struggling in adulthood, The Boys cast Haley Joel Osment, famous in his youth for The Sixth Sense and Forrest Gump, as a supe television star past the height of fame. Osment made his Broadway debut in David Mamet's play American Buffalo in 2008.

The "John and Sun-Hee" short in Diabolical is the anthology’s most heartwrenching installment, owing in part to Randall Duk Kim, voicing a husband desperate to find a cure for his dying wife.

The Obie Award winner is a co-founder of the American Players Theatre and frequently interpreted the works of Frank Chin, first in The Chickencoop Chinaman, the first Asian American-authored play to be produced professionally in New York.

In Gen V, Sean Patrick Thomas plays ex-superhero Polarity, a man with magnetic powers and father of main character Andre Anderson.

In addition, he has Off-Broadway credits in Shakespeare's Timon of Athens and Much Ado About Nothing.

Christian Slater, who narrates the Diabolical short “An Animated Short Where Pissed-Off Supes Kill Their Parents,” had quite the youthful days on Broadway.

Laila Robins is the steely Colonel Grace Mallory, who founded the titular Boys to fight against Vought. The Walking Dead star has a prolific stage resume that began with The Real Thing on Broadway in 1985.

Malcolm Barrett plays Seth Reed, a writer at Vought.

In 2024, he appeared in the play Brushstroke at Odyssey Theatre Ensemble.

Yup, that's Samuel L. Jackson performing a voice cameo as a hammerhead shark, Xander, who berates the Deep (a corrupt superhero with aquatic powers) for betraying his ocean bethern. It's a deep-cut homage to Jackson's initial pursuit of marine biology before he became recognized for his acting work.

Jackson's early theatre career included A Soldier's Play — said to have caught the attention of Spike Lee, who elevated the actor to greater prominence in films like School Daze and Do the Right Thing.
