The Infinity Stones are becoming an ever-more important aspect of the Marvel Cinematic Universe. Identified as the remnants of the six singularities that existed in the universe prior to the Big Bang - Space, Time, Reality, Mind, Power and Soul -- we have been slowly learning about all of them in Marvel Studios' movies for years now, and it won't be long before they are put center stage in the upcoming The Avengers: Infinity War - which will feature the Mad Titan known as Thanos working to collect all of the stones into the Infinity Gauntlet and possess the powers of a god.
But while hardcore comic book fans are fully aware of what the Infinity Stones are and what they do, there are surely many out there who are confused by all of it and have no way of keeping it all straight. That's exactly why we have created this handy little guide, which will not only explain exactly what all of the stones are, but where we first saw them in the Marvel Cinematic Universe and where they were last seen. Read on!
Where We First Saw It: Known as The Tesseract, the Space Stone was hidden for centuries on Earth in a church in Tonsberg, Norway, but in Captain America: The First Avenger we see it get stolen by Red Skull in 1942. It would later end up in the hands of S.H.I.E.L.D. (as first seen in Thor 's post-credits sequence).
Where We Last Saw It: After being stolen from S.H.I.E.L.D. by Loki in The Avengers, the Tesseract was put in a special case and transported back to Asgard by Thor (along with Loki in chains). It spent years locked away in Odin's Treasure room, but that's probably no longer the case given the expression on Loki's face when he spotted it at the end of Thor: Ragnarok.
What It Does: The Space Stone is utilized by Red Skull and Hydra during World War II as a weaponizable-energy source, but -- as seen in The Avengers - it's power is actually much greater than that. The Tesseract can actually be used to open up doors in space -- as demonstrated when Loki uses it to land on Earth and usher in an alien invasion.
