Does Tony Stark have another Arc Reactor embedded in his body? Other than the Arc Reactors in the Iron Man suits, I mean.

  • Have you seen Iron Man 3? I don't want to spoil it for you, but if you're seeing anything past then, you're going to get differing answers.

  • @Axelrod - Hence why I've listed the films in which he does, and the film in which he doesn't. Simples.

  • @Richard Yes, you did a great job updating your answer to include something I asked about before I was going to post. -_-

  • Going by the movies, I thought the reactor embedded in his chest did double duty - keeping him alive AND powering his suit. Didn't think the suit had its own reactor.

1 Answer 1


Throughout the Iron Man films (I, II and III) Tony Stark has arc reactors embedded in his chest. In the films they power the electromagnet that prevents shrapnel from entering his heart.

enter image description here

At the end of Iron Man III, he finally has the surgery needed to remove the shrapnel, obviating the need to have an arc reactor embedded into his chest.

Note that the latest MCU movies (Avengers II, Captain America: Civil War) are set after Iron Man III, which means that he doesn't have an arc reactor in his chest in these films.

    In fact, there are a couple of places in Civil War where you can see Tony's chest, and a scar is visible where the arc reactor once was.

    Does this mean Loki could have been able to control Iron Man if he had the patience to wait until now before attacking? geeksandcleats.com/wp-content/uploads/2014/11/… May 9, 2016 at 17:36

    Oh, well that answers my question about Tony not dying in Civil War.

    @JohnSensebe - Generally you'd fill such a large surgical cavity with a silicone implant or sterile collagen fleece.
