There’s a specific dread reserved for the “comic relief” sidekick. It smells like desperation and stale popcorn. I remember sitting in a theater for Batman & Robin, watching Chris O’Donnell try to salvage a script that hated him, and realizing that a bad sidekick is worse than a bad villain. A villain wants to kill you. A bad sidekick wastes your time.
I confess: I groaned when the Mandarin reveal happened in Iron Man 3. But time has been kind to Ben Kingsley‘s Trevor Slattery. He’s a cockroach in the nuclear apocalypse of the MCU—useless, delusional, completely indestructible. Now, in a twist that feels like a satirist’s fever dream, Marvel‘s Wonder Man series positions him as the franchise’s first official Phase 6 sidekick. Or as he insists: “mentor.”

The Actor and His “Mentor”
Marvel is leaning hard into meta-narrative for Wonder Man. The show isn’t just another superhero origin—it’s a Hollywood satire. The dynamic between Yahya Abdul-Mateen II’s Simon Williams and Kingsley’s Trevor Slattery is described as having a “white-hot affinity” built on their shared love of acting, despite being “wildly different people.”
Kingsley, in true character, refuses the sidekick label. “I would not classify myself as a sidekick; I am a mentor,” he declared in a recent featurette. Brilliant character work. In horror movies, the guy who thinks he’s the expert is usually the first one eaten by the werewolf. In the MCU, he’s the one who accidentally saves the day because he’s too oblivious to realize he’s in danger.
While the marketing pushes comedy, Simon Williams is a powerhouse in the comics. Having a washed-up actor as his “guy in the chair” deliberately subverts the Ned Leeds/Microchip trope. It suggests Phase 6 is willing to get weird—and that might be exactly what the franchise needs after the Multiverse Saga exhaustion.

Phase 6’s Sidekick Renaissance
Slattery isn’t alone. The upcoming slate is stacked with support dynamics that redefine the hero-sidekick relationship across the MCU.
For those tracking these alliances, our Marvel Cinematic Universe: The Ultimate Guide & Timeline breaks down the saga’s history. But looking forward, the roster reveals Marvel’s strategy.
Sam Wilson and Joaquin Torres continue the Captain America legacy, with Danny Ramirez’s Torres stepping into the Falcon role after Brave New World. They’ll reunite in Avengers: Doomsday this December. Namor brings his own lethal lieutenants—Namora and Attuma—confirmed via set photos from Bahrain. These aren’t quippy friends; they’re soldiers.
The tragic separations hit harder. Ned Leeds returns in Brand New Day without memories of Peter Parker—a melancholic setup straight from indie drama. Foggy Nelson and Karen Page anchor Daredevil: Born Again Season 2, grounding Matt Murdock’s vigilante chaos in human stakes.

Why Trevor Slattery Matters
By centering a failed actor as Simon Williams’ guide, Marvel signals Wonder Man will be character-driven chaos rather than plot-driven spectacle.
It creates necessary contrast. Bucky Barnes and the Thunderbolts bring deadly seriousness on one side. Trevor Slattery brings absolute absurdity on the other. If everyone’s a stoic badass, the movie’s boring. If everyone’s a joke machine, it’s annoying. You need the fools to make the kings look regal.
The show also positions itself as commentary on superhero culture itself—a celebrity-obsessed, image-driven industry where the line between hero and actor blurs. Simon Williams hiding superpowers while navigating Hollywood with his delusional “mentor” is either brilliant satire or a disaster waiting to happen.
Key Takeaways
- The court jester arrives. Trevor Slattery’s return as “mentor” brings meta-commentary to Phase 6’s opening chapter.
- Sidekicks are strategic. From Torres inheriting Falcon to Ned’s tragic memory wipe, support characters carry emotional weight in the new slate.
- Tone diversification. Wonder Man balances the serious Thunderbolts/Doomsday energy with absurdist comedy.
- Hollywood satire. The series is as much about celebrity as heroism—a risk that could pay off or alienate audiences.
FAQ: Wonder Man and Phase 6 Sidekicks
Is Trevor Slattery actually a superhero now?
No, and that’s the point. Trevor remains a powerless, slightly delusional actor. His role in Wonder Man is strictly as a “mentor” to Simon Williams—guiding him through celebrity, not combat. He’s the comic foil, not the muscle. The show seems designed to explore what happens when someone with no business being near superheroes becomes essential to one.
Will Ned Leeds become the Hobgoblin in the MCU?
No confirmation yet. His return in Brand New Day without Peter Parker memories suggests a blank slate. But the MCU loves tragic irony—putting Spider-Man against his forgotten best friend would fit the darker Phase 6 tone. The setup exists; whether they pull the trigger remains uncertain.
Why is Marvel emphasizing sidekicks in Phase 6?
Because the originals are gone. Iron Man, Black Widow, Captain America (Steve Rogers)—the anchors are dead or retired. Phase 6 must build new emotional centers, and sidekicks who’ve graduated to lead roles (Sam Wilson, Torres, Murdock’s allies) carry legacy without requiring legacy actors. It’s succession planning disguised as storytelling.
The strangest thing about Trevor Slattery’s return is how inevitable it feels. A decade ago, he was a punchline that nearly derailed Iron Man 3‘s reputation. Now he’s the emotional anchor of a Disney+ series about celebrity, heroism, and the absurdity of both.
Maybe that’s the secret Phase 6 needs. Not more cosmic threats or multiverse variants—but a washed-up actor from Croydon who thinks he’s a mentor, stumbling through a world that has no idea what to do with him.
Neither do I. But I’m watching anyway.
