Marvel revealed the news of Tony Stark’s retirement, due to take place at the end of the Civil War II comic series.
The new Iron Man in question is Riri Williams, a science genius who enrolls at MIT at just 15-years-old.
She comes to Stark’s attention after building her own model of the Iron Man suit.
But does this mean Downey Jr’s cinematic incarnation will be replaced by a black female actress?
Riri Williams is the new Iron Man, or should that be Iron Lady?
The star has played Iron Man an incredible six times in Iron Man 1-3, both Avengers movies and Captain America Civil War.
He’s due to play the playboy billionaire at least another three times.
Next year he’ll star alongside Tom Holland in Spider-Man: Homecoming, followed by Avengers Infinity War Parts One and Two in 2018 and 2019.
The star’s also confirmed he will make Iron Man 4, with a release date most like after 2020 in the Marvel Cinematic Universe’s Phase 4.
Assuming he finally hangs up the suit after a record breaking ten films, it wouldn’t be surprising if an actress replaced him in the iconic role.
There’s similar speculation surrounding Hugh Jackman’s Wolverine replacement.
The Aussie actor is currently filming Wolverine 3, his ninth movie as the immortal X-Men superhero.
With the Essex Corp reference in the end credits sequence of X-Men Apocalypse, fans are pretty certain he’s lined up to be replaced by X-23, a female clone of Wolverine.
Thor's also undergone a gender transformation in the comics, with a new storyline as a woman.
Civil War II sees Iron Man go head to head with Captain Marvel over the issue of preventing crimes before they happen, just like Tom Cruise's Minority Report.
Captain Marvel is to be introduced into the Marvel Cinematic Universe in 2018 and is likely to be played by Brie Larson.
