Avengers: Infinity War - EVERY Soul Stone Theory Ranked Worst To Best
9. It's Somehow Linked To Tony Stark
This one's arguably the most out-of-nowhere theory of them all, but thanks to a leaked piece of promotional art, it seems there may be a link between Tony Stark and the Soul Stone.
The artwork shows images of each of the Infinity Stones with the character they're most closely tied to: Captain America and the Space Stone (Tesseract), Star-Lord and the Power Stone (the Orb), Doctor Strange and the Time Stone (Eye Of Agamotto), Thor and the Reality Stone (Aether) and Vision and the Mind Stone. And the Soul Stone has Iron Man on...
Could that mean he's linked? Could that give weight to the slightly-wild-sounding rumour that the Starks used the Soul Stone and science to create a son when they could naturally?
Response
It's definitely interesting, but the idea of him BEING the Soul Stone is a little too far-fetched, even for the MCU. It could simply be that he's the Avenger who will find the Soul Stone?
That would be a lot more likely than him wearing an AI-enabled suit a lot of the time, which could somehow run schematics on his suit and body (and monitor his health) and NOT notice a big glowing magical Stone inside him.
