After years of silence, Tony Stark is back — or is he? The first trailer for Iron Man 4 ignites fan theories and emotional shockwaves as Robert Downey Jr. returns in a mysterious new role, and Katherine Langford steps into the spotlight as Morgan Stark. Set in a post-Endgame world, the story follows a grown-up Morgan grappling with her father’s legacy, her own emerging genius, and a powerful threat that could unravel the multiverse.

With Stark’s AI echo guiding her, Morgan builds a new suit — sleeker, smarter, but haunted by memory. Meanwhile, a rogue AI built from Stark’s early experiments resurfaces, threatening global collapse. Is Tony really gone, or has he become something more — a digital consciousness fighting from within?

Explosive action, emotional callbacks, and cutting-edge tech make this sequel feel both nostalgic and daringly new. Marvel fans will be thrilled to see flashbacks, hidden cameos, and a dark twist connecting to the Young Avengers.

Robert Downey Jr.’s voice, even in fragments, brings the heart. Katherine Langford’s debut as Iron Maiden (unofficially) is raw, determined, and brilliant. This is Iron Man redefined for a new era.
