The mystery of the final Infinity Stone has encouraged many fan theories, as the wait continues for Marvel‘s Avengers Infinity War.
More popular ideas have suggested Heimdall has the gem or it’s somewhere in Wakanda.
But then last week some promo art leaked of the six Infinity Stones, with one superhero connected to each one.
Each character is known to be in possession of a specific Infinity Stone, or as come across one in the past.
However the Soul Stone is included and appears to have a link to Iron Man. But in what way?
A theory that has resurfaced references a link from Iron Man 2, when the deceased Howard Stark, Tony’s father, leaves him a recorded message.
He says: “What is and always will be my greatest creation, is you.”
The theory goes, therefore, that Howard created Tony with the Soul Stone some how.
After all, he had his son later in life and let’s not forget that each Infinity Stones is encased in a different form.
With this in mind, would Thanos have to kill Iron Man to have the Soul Stone in his possession?
Avengers Infinity War will be released in UK cinemas on April 27, 2018.
