Actually he might be back in his own series
On Thursday evening, news broke that actor Robert Downey Jr. is already in talks to return as Tony Stark/Iron Man for a new Disney+ TV series. If true, Tony would feature in a show called Iron Heart, based on the Marvel comic book series and character of the same name. In contemporary Marvel comics, Iron Heart is the alias for a new version of Iron Man, who is actually a woman named Riri Williams. In the series, Riri takes over the mantle of Iron Man from Tony Stark, who basically retires.
