'Wonder Man' Ending Explained: Will Simon Return to MCU in 'Avengers: Doomsday'?

Published 01/28/2026, 2:53 AM EST

Wonder Man may have wrapped neatly, yet it leaves viewers squinting at the exit sign, convinced another scene is coming. Viewers were enamored by the series as it tracked Hollywood actor Simon Williams navigating sudden powers, fame anxiety, and reluctant heroism through sharp industry satire. Taking a break from Yahya Abdul Mateen II and Ben Kingsley's comedic dynamic, one is left with more questions about what will happen to Simon Williams.

That ending feels as satisfying as the journey itself, while deliberately leaving just enough unresolved to invite larger Marvel speculation.

Trevor Slattery deliberately resurrects the Mandarin persona to redirect blame after Simon Williams accidentally detonates the film set with uncontrolled ionic energy. By recording a public confession, Trevor shifts the blame to himself, reframing the explosion as ideological theater rather than negligence, shielding Simon from professional and legal ruin.

The blast from the past of Iron Man 3 did not amuse the authorities, as they took action immediately. Trevor was not just arrested by the Department of Damage Control (DODC) but was also sent to the facility in a highly secured black box, making escape impossible for him.

With Trevor Slattery incarcerated, the Wonder Man film resumes production, replacing him with Joe Pantoliano as Barnaby. The finished movie premieres to commercial triumph, and Simon Williams finally earns the emotional approval of his brother, Eric Williams, who recognizes his legitimate talent. Yet success curdles into guilt. Simon understands that his acclaim rests on Trevor’s erasure, not his own merit, prompting him to reject lucrative contracts and redirect his ambition toward correcting the imbalance that fame has politely concealed.

Simon Williams engineers his rescue with performance rather than brute force. He embeds himself near the desert facility by shadowing prison guard Chuck Eastman, claiming role preparation, while quietly paying off Eastman’s family debts to remove collateral damage from the plan. Inside the facility under the alias Alfonso, Simon locates Trevor Slattery and finally stops suppressing his ionic abilities. He flies through the prison roof to escape as 'Everybody’s Talkin’ plays, marking acceptance of power without theatrical pretense. 

Do You Need to Watch 'Wonder Man' Before 'Avengers: Doomsday?'

For a series that happily broke the Marvel mold, the ending is unusually tidy, which somehow leaves fans asking even more questions.

Will Wonder Man reappear in Avengers: Doomsday?

Marvel Studios insists nothing is confirmed, which in practice means everything is possible. Simon Williams exits Wonder Man without a teaser card, yet Andrew Guest promptly informs audiences that the man now qualifies as battlefield furniture for Doctor Doom.

The series also positions Simon geographically and narratively. California already hosts Ant-Man, She-Hulk, and Shang-Chi, echoing Wonder Man’s West Coast Avengers roots. His bond with Trevor Slattery further links him to Shang-Chi, creating a plausible entry point into Avengers-level coordination.

Casting speculation surrounding Avengers: Doomsday remains fluid, with ongoing debate about Tom Holland and Chris Pratt appearances. Within that atmosphere, Yahya Abdul-Mateen II joining the speculative roster feels less fanciful, especially given Marvel’s habit of quietly upgrading breakout characters into ensemble players.
