The concept of “Infinity” as a collection of all-powerful artifacts was not introduced all at once, but rather evolved over several years. The first of these objects to appear was the Soul Gem. It debuted, unnamed, in Marvel Premiere
#1 (April 1972), created by writer Roy Thomas and artist Gil Kane. In this story, the High Evolutionary bestows the mysterious gem upon the artificial man he created, Adam Warlock, to aid him on his journey.
The idea was expanded upon significantly by writer and artist Jim Starlin, who became the primary architect of Marvel's cosmic sagas. Starlin took a deep interest in Adam Warlock and the Soul Gem, eventually revealing its name and consciousness. He then introduced five other “Soul Gems” in a storyline involving thanos in the mid-1970s. However, it wasn't until the 1990 limited series The Thanos Quest
that Starlin fully codified the concept. He retconned the six “Soul Gems” into the singular Infinity Gems, each with a unique name, color, and dominion over a specific aspect of existence. This series, followed by the universe-altering event The Infinity Gauntlet
(1991), cemented the Gems' place as the most powerful and sought-after objects in the Marvel Universe, a status they have held ever since.
The origin of these cosmic powerhouses differs significantly between the primary comic book continuity and the cinematic universe, reflecting the different narrative needs of each medium.
The origin of the Infinity Gems in the Earth-616 comics is as epic and complex as their power. Initially, their creation was shrouded in mystery. The Elders of the Universe, ancient beings who had encountered them, knew only that they were objects of unimaginable power. The definitive origin was later revealed in a crossover with the Malibu Comics' Ultraverse. It was established that the six Gems (along with a forgotten seventh) were the remnants of a nigh-omnipotent, primordial cosmic entity named Nemesis. Existing alone in a void before creation, this being grew lonely and, in an act of cosmic despair, ended its own existence. The cataclysm of its suicide shattered its consciousness and power, and its core essence crystallized into the six primary Infinity Gems. Each Gem contained a facet of this being's boundless power. This origin explains their synergistic nature; when brought together, they don't just add their powers, they multiply them exponentially, seeking to reform the omnipotent being from which they were born. This origin story also introduced the Ego Gem, the seventh gem containing the core consciousness of Nemesis, which sought to reunite with the others. Later storylines have sometimes simplified or retconned this, suggesting the Gems are simply primordial artifacts from the creation of the universe, similar to the MCU's origin, but the Nemesis story remains the most detailed account of their genesis.
The MCU (designated as Earth-199999) presents a more streamlined and scientifically-grounded, albeit still cosmic, origin for the artifacts, now known as the Infinity Stones. This explanation was first provided by The Collector in Guardians of the Galaxy
(2014) and later reiterated by Wong in Avengers: Infinity War
(2018).
According to this canon, before the universe began, there was nothing. Then, the Big Bang erupted, creating all of existence. At this moment of creation, six elemental crystals were formed, each one governing an essential aspect of the new universe. These are the Infinity Stones.
“Before creation itself, there were six singularities. Then the universe exploded into existence, and the remnants of these systems were forged into concentrated ingots… Infinity Stones.”
- The Collector
This origin positions the Stones not as the remains of a being, but as fundamental constants of the universe itself, like laws of physics given tangible form. They were scattered across the cosmos and wielded by ancient cosmic beings, such as the Celestials (as seen with Eson the Searcher using the Power Stone). Over millennia, they were housed in various containers and sought by those who understood their true potential, culminating in the obsessive, galaxy-spanning quest of Thanos to unite them and impose his will on the universe. This simpler origin story makes the Stones' purpose and power immediately understandable to a broad film audience without requiring deep dives into cosmic lore.
The concept of “Infinity” is primarily understood through its physical manifestations: the Gems/Stones and the devices created to wield them.
In the comics, the Infinity Gems are the core components. They are small, smooth, ovular jewels, and their colors have notably changed over the years to align with the MCU's popular depiction.
Infinity Gem | Original Color | Modern Color (Post-2017) | Aspect of Reality | Known Powers and Abilities |
---|---|---|---|---|
Soul Gem | Green | Orange | Soul | Allows the wielder to observe, manipulate, and steal the souls of the living and the dead. Contains a pocket dimension called Soul-World. Can devolve or evolve beings. At its peak, can control all life in the universe. |
Time Gem | Orange | Green | Time | Grants total control over the past, present, and future. Allows for time travel, stopping time, and creating time loops. The wielder can see all possible timelines and exist at all points in time simultaneously. Can age or de-age beings or entire worlds. |
Space Gem | Purple | Blue | Space | Grants control over space itself. Allows for teleportation (of oneself, others, or objects) to any location imaginable. Can warp or rearrange space, increase speed, and make the wielder omnipresent. Its power can hold entire universes in one's hand. |
Mind Gem | Blue | Yellow | Mind | Taps the wielder into the universal consciousness. Grants vast psionic abilities, including telepathy and telekinesis, on a cosmic scale. Can connect with every mind in existence simultaneously. Allows the user to bring thoughts and dreams into reality. |
Reality Gem | Yellow | Red | Reality | Arguably the most powerful and dangerous Gem. Allows the wielder to alter reality to their whim, violating all known laws of science and nature. It can create any reality or illusion the user can conceive. It requires great care, as its effects can backfire without the other Gems to stabilize it. |
Power Gem | Red | Purple | Power | Accesses all power and energy that ever has or ever will exist. It enhances the power of the other five Gems. On its own, it grants the user superhuman strength, durability, and the ability to manipulate any form of energy, making them physically unstoppable. |
Other Key Artifacts and Concepts:
The MCU's Infinity Stones are more rugged and rock-like in their raw form. Their colors have been consistent since their introduction and have since been adopted by the comics.
Infinity Stone | Color | Containment Unit(s) | Aspect of Reality | Known Powers and Abilities |
---|---|---|---|---|
Soul Stone | Orange | None (Guarded on Vormir) | Soul | The least understood Stone. Can manipulate life and death and requires a soul-for-a-soul sacrifice to obtain. Used by Thanos to identify the real Doctor Strange among his duplicates. Appears to have a form of sentience. |
Time Stone | Green | Eye of Agamotto | Time | Allows for precise control over time, including creating time loops (as used against Dormammu), reversing time locally (repairing Hong Kong), and viewing millions of possible futures (as done by Doctor Strange). |
Space Stone | Blue | Tesseract | Space | Powers interstellar travel by opening wormholes. Used by Loki to open the portal for the Chitauri invasion. Can project powerful energy blasts. Its energy was the source of Captain Marvel's powers. |
Mind Stone | Yellow | Scepter, Vision's Forehead | Mind | Can control the minds of others (as used by Loki). It granted Scarlet Witch and Quicksilver their powers. When housed in Vision's synthetic body, it granted him sentience, consciousness, and energy projection abilities. |
Reality Stone | Red | Aether (a liquid, parasitic form) | Reality | Can convert matter and create realistic, large-scale illusions (as used by Thanos on Knowhere). Malekith planned to use its convergence-powered state to revert the universe to eternal darkness. |
Power Stone | Purple | The Orb, Cosmic-Rod | Power | An incredibly destructive force. Capable of destroying entire planets with a single touch to the surface. It grants the wielder immense energy projection and physical power. The Guardians of the Galaxy could only wield it together by sharing its energy load. |
Other Key Artifacts:
The pursuit of infinite power has defined many of Marvel's greatest heroes and villains.
The Avengers
to 2019's Avengers: Endgame
is defined by the Infinity Stones. The Mind Stone created two of their members (and one enemy, Ultron), the Time Stone was guarded by their ally Doctor Strange, and their ultimate triumph came from Tony Stark's sacrifice, using a custom-built Gauntlet to snap Thanos and his armies out of existence.The name “Infinity” is synonymous with several of Marvel's most epic and consequential story arcs.
This two-issue miniseries is the direct prequel to The Infinity Gauntlet. It chronicles in detail how Thanos, recently resurrected by Mistress Death, systematically hunts down and acquires each of the six Infinity Gems. He doesn't use brute force, but rather cunning, intellect, and ruthless strategy to outwit the ancient Elders of the Universe who possess them—including the Champion, the Gardener, the Collector, and the Grandmaster. It's a masterclass in showcasing Thanos's threat level even before he assembles the Gauntlet.
This is the benchmark for all cosmic events in comics. With the Gauntlet complete, Thanos ascends to godhood. With a literal snap of his fingers, he erases half of all living beings in the universe. The surviving heroes of Earth and cosmic champions launch a desperate, doomed assault on his fortress. The story's climax is a masterwork of cosmic drama, involving Thanos defeating Eternity itself, only to lose the Gauntlet due to his own hubris and a surprise intervention by his captive “granddaughter,” Nebula. The Gauntlet ultimately falls to Adam Warlock, who undoes the damage and becomes the new guardian of Infinity.
More than a single event, the “Infinity Saga” is the overarching narrative of Phases One, Two, and Three of the Marvel Cinematic Universe. From the Tesseract's appearance in Captain America: The First Avenger
and the Scepter in The Avengers
to the final confrontation in Avengers: Endgame
, the story of the Infinity Stones is the central thread.
Avengers: Infinity War
(2018) adapted the core premise of The Infinity Gauntlet: Thanos's successful quest to gather the stones and wipe out half of all life, ending on a shocking downbeat note with the heroes' utter failure.Avengers: Endgame
(2019) served as the grand finale, focusing on the survivors' “Time Heist” to retrieve the Stones from the past, undo the snap, and fight a final, epic battle against a past version of Thanos. It culminates in Iron Man's sacrifice, using the Stones to save the universe, providing a definitive conclusion to the saga.Despite its name, this major comic book event by Jonathan Hickman is not directly related to the 1990s sagas. The story has two main plots: the Avengers heading into space to fight an ancient race known as the Builders, and Thanos invading a defenseless Earth in their absence. While the Infinity Gems are a central part of Hickman's overall Avengers run that precedes this event (the Illuminati gathered them to prevent multiversal “Incursions,” only for the Gems to shatter), they are not the focus of the Infinity event itself. The name primarily serves as a branding link to Marvel's cosmic line.
