WHERE ARE THE INFINITY STONES IN THE MOVIES?
Ah, now we have come to the crux of the matter. In Guardians of the Galaxy, it was explained that the six “stones” are actually six singularities whose existence preceded the Big Bang and were pressed into stones after the universe began.
Different from their comic book counterparts, the Infinity Stones are only physical gems at times, occasionally taking the form of strange gases or powerful cubes. Some of them have featured largely in the MCU while disguised, with their true nature revealed after the fact.
Here’s the location and form of each Infinity Stone, in order of their first appearance in the Marvel Cinematic Universe. It’s accurate to the timestamp on this post.
THE SPACE STONE
The first Infinity Stone to appear in a Marvel film, this one’s form — as a glowing blue cube about the size of a softball — was a neat red herring for another mighty Marvel Comics artifact, the Cosmic Cube. The Hydra agent called the Red Skull sought it in Captain America The First Avenger. Then it was recovered by S.H.I.E.L.D. in the 21st century, stolen by Loki and subsequently used to open the portal that brought the Chitauri army to New York in The Avengers. At the last scenes of The Avengers, Thor handed it back to Asgard’s armory for safekeeping.
The Tesseract was seen multiple times in Odin’s treasure room in Thor Ragnarok, in which all of Asgard was destroyed utterly by the fire demon, Surtur. The last time it was seen was when Loki visited the vault to recover Surtur’s skull.
Ragnarok gave us a good look at the god of mischief giving it a significant glance. And because the plot of Avengers Infinity War will have to relate to all six Infinity Stones — so it perhaps wasn’t destroyed along with Asgard — it appears likely that the Tesseract will ultimately be revealed to be in Loki’s grasp once again. Its characteristic color is blue.
THE MIND STONE
The Mind Stone first appeared, secretly, in The Avengers. Initially hidden in the tip of Loki’s mind-control scepter, the stone is one of the most well-traveled and consequential Stones of the bunch.
The Scepter was a gift from Thanos, who’d also financed the Chitauri army and rescued Loki from the void after he fell from Asgard’s rainbow bridge in Thor, in exchange for Loki leading the army to Earth. During the events of The Avengers, that scepter was confiscated for study by S.H.I.E.L.D., yet in Captain America The Winter Soldier, the stone was re-confiscated by Hydra in the latter’s takeover. It was used to awaken the powers of the Scarlet Witch and Quicksilver, before being recaptured by the Avengers in The Avengers Age of Ultron.
Tony Stark and Bruce Banner used the scepter to create the evil artificial intelligence Ultron, who was the first to realize that its power actually resided in the Mind Stone, which was inside the scepter. Ultron tried to use the Mind Stone to create a new body for himself.
That very body was recovered by the Avengers before he could insert his soul into it, and brought to life as the android the Vision, endowed with sentience by the Mind Stone embedded in his forehead.
For the time being, the Mind Stone is still embedded in the Vision’s forehead. It’s yellow.
THE REALITY STONE
The Reality Stone is seen mainly only in Thor The Dark World, where its malleable substance, called the Aether, was used as a weapon by the Dark Elf baddie Malekith. By the end of the movie, the Reality Stone was retrieved by Asgardian forces and brought to the Collector, and ancient being who … collects things, for safekeeping. Apparently, keeping two Stones in close range in Asgard’s armory might be too dangerous, and they already found the Space Stone, or Tesseract.
For all we know, the Collector still has the Reality Stone in his hands, though his base of operations was quite badly trashed in Guardians of the Galaxy. It is red.
THE POWER STONE
Speaking of Guardians of the Galaxy, its plot was centered around the Power Stone, recovered from an ancient ruin by Peter Quill and sought by the Collector and Ronan the Accuser. Ronan was supposed to be taking it for Thanos, but instead decided to use its powers to try to take revenge on the people of the planet Xandar.
After Ronan was defeated by the Guardians of the Galaxy, the Power Stone was given to Xandar’s Nova Corps, and is presumably in their possession still. It is purple.
THE TIME STONE
The Time Stone is seen prominently in Doctor Strange, where the eponymous hero uses the Eye of Agamotto’s ability over time to take down the demon Dormammu. Earth’s first sorcerer, Agamotto, had bound the Time Stone into a pendant thousands of years before.
At the end of Doctor Strange, Doctor Strange returns the Eye to the stronghold of Kamar-Taj in Nepal, where it likely still remains. Its color is green.
