Since the Marvel Cinematic Universe began in 2008, there has been only one endgame: war. In 2018, Marvel Studios will mark the end of an era in Avengers: Infinity War from directors Joe and Anthony Russo. The big bad Thanos seeks the six Infinity Stones, ancient relics from beyond time and space that are too powerful for any one person to wield. With his Infinity Gauntlet, Thanos can literally hold all the power in the universe in his hand, and it’s up to the superheroes of the Marvel Universe to stop him.

While several Marvel movies have dealt directly with the Infinity Stones, such as in 2012’s The Avengers or 2014’s Guardians of the Galaxy, others not so much. It can get even more confusing, as each Stone is capable of specific powers, and they’ve all been scattered about all over the place.

So before Infinity War begins, here is a handy, up-to-the-minute guide to all the known Infinity Stones, their appearances, and their current whereabouts. This page will be updated to reflect current releases of Marvel movies. In 2018, there will be Black Panther in February and Avengers: Infinity War in May.

This has been updated to reflect the most recent Marvel movie, Thor: Ragnarok.

What Are the Infinity Stones?

Predating the Big Bang, the Infinity Stones are six singularities that compress the powers of the universe. The stones have been used to wipe out whole civilizations with a single gesture, and so the stones have been scattered throughout the universe. Much of what is known about the Infinity Stones was told by the Collector in Guardians of the Galaxy.

In the comics, the Infinity Stones were known as Infinity Gems, and the first of which (the Soul Gem) was introduced in Marvel Premiere #1 in April 1972. More came, and, eventually, they were plot devices for Jim Starlin’s 1991 series The Infinity Gauntlet, which will be loosely adapted into next year’s Avengers: Infinity War. (The film shares its title with The Infinity War, released in 1992.)

In The Infinity Gauntlet, Thanos is madly in love with the personification of Death and tries to woo her by amassing all the power in the universe. He collects the gems and uses them to crush the Marvel Universe until his granddaughter Nebula dons the Gauntlet and reverses his destruction. Afterward, the powerless Thanos ends up working on a farm. There are worse ways to go out.

As stated, there are six of them in the Marvel Cinematic Universe. They are:

Thor Avengers Infinity Stone
The Tesseract, as seen in 'The Avengers.'

The Space Stone (the Tesseract, Blue)

Appears in: post-credits scene of Thor (2011), Captain America: The First Avenger (2011), The Avengers (2012), and Thor: Ragnarok (2017).

What it does: With the ability to generate wormholes, it allows species to travel great distances in an instant. Loki uses the Tesseract to unleash the Chitauri in New York in The Avengers. This event is known as the Battle of New York, but it is also sometimes referred to as “the Incident.”

Current whereabouts: Since The Avengers, the Tesseract was kept in Odin’s vault on Asgard. But it’s a safe bet that Loki swiped it at the end of Thor: Ragnarok.

Mind Stone Infinity War Vision

The Mind Stone (Loki’s Scepter/Vision, Yellow)

Appears in: The Avengers (2012), Avengers: Age of Ultron (2015), and Captain America: Civil War (2016).

What it does: Capable of controlling minds and enhancing intelligence, Thanos gives the Mind Stone to Loki to wield in his scepter to build an army in The Avengers. After Loki’s defeat, his scepter falls into the hands of Hydra commander Baron Wolfgang von Strucker, who uses it for human experimentation, where he turns two poor Sokovian siblings into Quicksilver and Scarlet Witch.

Throughout the events of Avengers: Age of Ultron, Thor fuses the Mind Stone into Tony Stark’s A.I. assistant, J.a.R.V.I.S., to create Vision.

Current whereabouts: It’s basically Vision, who is still an active Avenger under the command of Tony Stark at the end of Captain America: Civil War.

Thor Aether Infinity Stone
The Aether, also known as the Reality Stone, in 'Thor: The Dark World.'

The Reality Stone (the Aether, Red)

Appears in: Thor: The Dark World (2013).

What it does: Turned into a liquid weapon called the Aether by Malekith (Christopher Eccleston), the Reality Stone is able to return the universe to its pre-Big Bang state.

Current whereabouts: Knowing of its horrific power, the Asgardians gave the Aether to the Collector in the post-credits scene of Thor: The Dark World. The Asgardians trusted the Collector to keep it separate from the Tesseract on their world, knowing it can be dangerous keeping as much as two Infinity Stones together on one planet. As far as anyone knows, it’s still with the Collector in his ruined home on Knowhere.

The Orb Guardians of the Galaxy
The Orb in 'Guardians of the Galaxy.'

The Power Stone (in the “Orb,” Purple)

Appears in: Guardians of the Galaxy (2014).

What it does: As demonstrated when it was used by Star-Lord (Chris Pratt) to kill Ronan the Accuser (Lee Pace), the Power Stone is nothing but raw power and can destroy whole civilizations, let alone an emo warlord.

Current whereabouts: Star-Lord unknowingly salvaged the Power Stone contained in an “orb” at the beginning of Guardians of the Galaxy. Upon learning of its power, the Guardians kept it from Ronan, and it’s now safe on Xandar with the Nova Corps, the military police of the Nova Empire.

Eye of Agomotto Doctor Strange Avengers
The Eye of Agomotto in 'Doctor Strange.'

The Time Stone (the Eye of Agomotto, Green)

Appears in: Doctor Strange (2016).

What it does: Used by Doctor Strange (Benedict Cumberbatch) to create a time-loop to destroy Dormammu, the Time Stone can alter and manipulate time.

Current whereabouts: Under custody of the Masters of the Mystic Arts (namely Wong) at Kamar-Taj in Kathmandu, Nepal.

The Soul Stone (Orange)

Appears in: TBD.

What it does: In the comics, the Soul Gem can steal, control, and alter the souls of the living and the dead. It might even be able to control all life in the universe if the films behave like the comics do. Nobody in the known MCU has possession the Soul Stone, yet.

Current whereabouts: ???

Thanos Infinity Gauntlet MCU

The Infinity Gauntlet (Gold)

Appears in: Thor (2011), Avengers: Age of Ultron (2015), Thor: Ragnarok (2017).

What it does: To control the powers of the Infinity Stones, one must wield the Infinity Gauntlet. True to its name, it is a literal glove with slots on the knuckles and the back of the hand to place the stones in them.

Current whereabouts: A fake gauntlet was kept in Odin’s vault on Asgard. A left-hand gauntlet is shown in the end credits of Avengers: Age of Ultron, worn by Thanos, who mutters to himself: “Fine. I’ll do it myself.”
