Wonder Man finale: Simon frees Trevor after on-set explosion and goes Hollywood

Gamesradar reports the Wonder Man finale closes with Simon Williams rising as a Hollywood star while Trevor Slattery takes the blame for an on-set explosion by reprising the Mandarin, is arrested by Damage Control, and is later rescued by Simon. In the episode Simon receives the original Wonder Man glasses, stars in the movie to rave reviews, and is told by his agent he has the "pick of projects"; Joe Pantoliano replaces Trevor as Barnaby at the premiere.

Simon's prison "research"—posing as trainee Alfonso with small-town officer Chuck—allows him to reach Trevor, reconcile, and use his ionic energy to break Trevor out through the roof, then secretly deposit money into Chuck's account for his daughter's medical fees. The finale also showcases more of Simon's abilities—extraordinary strength, ionic rays and flight—while the creators were non‑committal on whether he is a mutant; comics lore suggests ionic energy can grant near‑invulnerability.

Separately, Damage Control Deputy Secretary Heyerdahl confirmed Doorman will be "monitored for the rest of his life" and is the subject of government experiments. The show offers no post‑credits scenes and does not reveal Simon and Trevor's final destination.
