In one way or another, Avengers: Endgame is expected to mark the end of Robert Downey Jr.'s long run in the Marvel Cinematic Universe, and if he joins, Iron Man is almost certain to be with him to go.
More specifically, Tony Stark will go, but that does not mean that Iron Man will disappear from the MCU forever.
Iron Man's armor does not have to be pushed into a closet to rust. Like Captain America, Disney could easily find a way to replace it.
The comics put someone on armor on several occasions when Iron Man was disabled, MIA, or temporarily dead (a passing death is a common condition in the US superhero world).
To be honest, Gwy neth Paltrow and Don Cheadle are unlikely to increase their stake in the MCU. Paltrow appeared to be rather disappointed with acting in general and Marvel in particular – though she later appeared in Spider-Man: Homecoming and Avengers: Infinity War and at age 54 Cheadle  image = "image" class = "Lazyimage Lazyoad" data-src = "https://hips.hearstapps.com/digitalspyuk.cdnds.net/17/26/1498486014-gwneth-paltrow-pepper-potts-marvel .jpg crop = 1XW: 1xh, center, top & resize = 480: * "/> [19659006(Disney[196590074LookingaußerhalbderMCUesgibtandereCharakterediekürzlichdieRolledesIronManübernahmenbevorerzuseinenboshaftenWegenzurückkehrtehatteDoctorDoomseinenStatusals"InfamousIronMan"DerZusammenschlussvonDisneyundFoxistaufdemWegwasbedeutetdassdieFilmrechtefürDoomzurückkehrenwerdeninMarvelStudiosobwohlesunwahrscheinlicherscheintdassderberühmteSchurkeineineheroischeRollegeratenwürde
another successor was Riri Williams, a genius teenager The African-American engineering student, d She had taken care of her own suit, was looked after by Tony and eventually received the title "Ironheart". It would certainly give the MCU the opportunity to continue its slow progress towards better diversity and representation – and we will take this opportunity to call Amandla Stenberg a perfect casting choice.
Even if Marvel does not choose a new Iron Man, there will still be an ingenious tech free in the Avengers lineup – and many Candidates to step into the rocket-propelled shoes.
Bruce Banner already plays a similar role in the Avengers (if he does not turn into the much less intelligent Hulk, at least) and even got a turn in Tony's Hulkbuster suit in Infinity War .

Likewise, we have Spider-Man. Peter Parker is traditionally one of Marvel's greatest inventors Even though the MCU has not really explored this aspect of Tom Holland's youthful version of the character yet, he also received his own "Iron Spider" suit in the Infinity War
O Although Marvel really wants to take a step back from the often flawed Tony (who accidentally calls the Apocalyptic-minded Ultron (unless we do not forget it), there is one person widely recognized as his intellectual equal and probably as their superior.
This is Black Panther's little sister Shuri, who has already established herself in her short tenure at MCU T & # 39; Challa's version of Q, equipping him with amazing combat gear AND reversing the winter soldier's murderous brainwashing. As far as we can tell, it has also developed most of the technology in Wakanda's sophisticated capital.
It makes Tony's armor and death robots look rather miserable in comparison, and it helps everyone worship the upcoming actress Letitia Wright.
If that Everything is not enough for the Marvel Studios, there is still a degree they could keep Tony Stark to farewell after Downey's departure, but we really do not recommend it.
There was a notorious story in the Avengers comics titled "The Crossing", which basically revealed the iron Man had been secretly evil for centuries: The Avengers recruited a 19-year-old Tony from the past to help them and the Story ended with older Tony coming to himself to ga Heroic Sacrifice ™.
We can not see how they make Downey's Iron Man evil, but they could introduce a younger version of the character, if they really want that. But if the president of Marvel Studios, Kevin Feige, is not revealed even to the crazy puppet of Supervillains, this seems highly unlikely.
Avengers: Endgame will be released on April 26th.
