This artwork debuted on Reddit, with some Redditors theorizing that Iron Man is the most important Marvel hero, so they put him on the Soul Stone artwork just because of that, and not because he has any connection to the Soul Stone. Regardless, we will likely get our first glimpse of the Soul Stone in Avengers: Infinity War, hitting theaters May 4, which will be followed by the final Phase 3 movie, Avengers 4 on May 3, 2019.
It’s possible that there may have been a connection to Tony Stark with the Soul Stone all along, but we won’t know for sure until Avengers: Infinity War hits theaters on May 4.
A new promo poster for Infinity War showcases all of the Infinity Stones, which seems to offer a big hint at where the Soul Stone may be.
One of the biggest mysteries yet to be solved in the Marvel Cinematic Universe is when and where fans will finally get to see the sixth and final Infinity Gem, the Soul Stone. Many thought that Black Panther would reveal where the Soul Stone is, since it’s the last movie before Avengers: Infinity War hits theaters on May 4, but that never happened, so it seems we’ll finally get to see it in Infinity War.
