In Iron Man 4, Morgan Stark (Katherine Langford) is determined to reunite with her father, Tony Stark, after his tragic death.

Using her father’s advanced technology, she embarks on a dangerous journey through the multiverse in search of him. After traveling across multiple dimensions, Morgan finally finds an alternate version of Tony and convinces him to return to her universe. However, upon their return, things begin to feel off. In this universe, Tony Stark died a hero, and this new Tony seems confused by the world he’s now in.

As time passes, Morgan notices the alternate Tony’s behavior grow more secretive. He starts building new technology, including an arc reactor, but something about his actions feels wrong. One day, Morgan discovers him constructing a mysterious suit and questions his true motives. It’s then that the truth is revealed—this is not Tony Stark at all, but Doctor Doom, using his genius and deception to execute a dark plan. Morgan realizes too late that bringing this version of “Tony” into her world was a dangerous mistake, setting the stage for a showdown between her and Doom in a battle for the future of Iron Man’s legacy.
