The Infinity Gems

Part 1: The Dossier: An At-a-Glance Summary

Part 2: Origin and Evolution

Publication History and Creation

The artifacts that would become the Infinity Gems were introduced gradually and without a grand, overarching plan. The first to appear was the Soul Gem, which debuted alongside its most famous wielder, Adam Warlock, in Marvel Premiere #1 (April 1972). Created by writer Roy Thomas and artist Gil Kane, this gem was a key component of Warlock's early stories. Over the next several years, other “Soul Gems” appeared in various Marvel titles. The concept was unified and expanded upon by writer and artist Jim Starlin, a pivotal architect of Marvel's cosmic lore. In a storyline culminating in Avengers Annual #7 (1977), the villain Thanos gathered all six gems for the first time in a plot to extinguish the stars. It was here they were depicted as a collective set of immense power. However, the term “Infinity Gems” was not coined until Starlin returned to the concept for his 1990 miniseries, The Thanos Quest. This story established their definitive names, colors (at the time), and specific domains of power, cementing them as the ultimate prizes in the Marvel Universe. This led directly into the 1991 blockbuster event, The Infinity Gauntlet, which elevated the Gems from a powerful cosmic plot device to iconic artifacts recognized by comic fans everywhere.

In-Universe Origin Story

The true origin of the Infinity Gems is a matter of cosmic legend, with conflicting accounts befitting their primordial nature.

Earth-616 (Prime Comic Universe)

The most widely accepted origin story in the prime comic continuity is one of cosmic suicide and rebirth. Long before the current reality, there existed a lonely, omnipotent cosmic being known as Nemesis. Consumed by an unbearable solitude, this entity eventually chose to end its own existence. From the cataclysmic end of this being, its divine essence shattered and eventually reformed into the six Infinity Gems, with a forgotten seventh gem, the Ego Gem, containing the faint echo of Nemesis's consciousness. Each Gem inherited a facet of Nemesis's absolute power over existence. They were scattered across the nascent universe, destined to be sought by those who craved their power. This origin was established in the crossover series Avengers/Ultraforce (1995). For many years, this was the definitive account. However, more recent narratives have sometimes simplified this, aligning closer to the MCU's origin by describing the Gems as remnants of six singularities that existed prior to the Big Bang, condensed into their current forms as the universe expanded. While both origins exist in canon, the Nemesis story remains the more detailed and dramatic explanation for their sentient-like qualities.

Marvel Cinematic Universe (MCU)

The origin of the Infinity Stones in the MCU is more direct and was explicitly detailed in the films Guardians of the Galaxy (2014) and Avengers: Infinity War (2018). As explained by The Collector and later by Wong, the Stones predate the universe itself. Before creation, there was nothing. Then, the Big Bang erupted, creating the universe and birthing six elemental crystals from the primordial singularities that existed before it. These six singularities were: Space, Mind, Soul, Reality, Power, and Time. Shortly after the universe began, ancient and powerful cosmic_entities like the Celestials harnessed the immense energy of these crystals, forging them into the ingots now known as the Infinity Stones. This origin story streamlines the comic's lore for a cinematic audience, removing the Nemesis entity and establishing the Stones as fundamental, almost naturalistic, components of the MCU's cosmology. Their power is so immense that they can only be wielded by beings of incredible strength or through a containment device like the Infinity Gauntlet. As stated by Wong, the Stones act as a cosmic balancing act, with each one controlling an “essential aspect of existence.”

Part 3: The Six Primal Forces: Composition, Powers & Wielders

The six Infinity Gems (or Stones) are the core of the set, each governing a fundamental aspect of the universe. Their powers are both specific and boundless; a master of a Gem can use it in subtle ways or to warp the fabric of reality on a cosmic scale. A key point of divergence between the comics and the MCU is their coloration.

Gem/Stone Earth-616 Color (Classic) MCU & Modern Comics Color Core Concept
Soul Green Orange Life, Death, and Spirit
Power Red Purple Energy and Physical Might
Time Orange Green Causality and the Flow of Time
Space Purple Blue Distance and Location
Reality Yellow Red The Fabric of What Is
Mind Blue Yellow Thought and Consciousness

Part 4: The Seventh Gem and Other Anomalies

Beyond the core six, other Gems have appeared in Marvel's history, though their canonicity or significance varies.

The Ego Gem (Earth-616)

The true seventh Infinity Gem, the Ego Gem, was revealed during the Avengers/Ultraforce crossover. It contained the last remnant of the cosmic entity Nemesis's consciousness. When the six other Gems were gathered, it allowed Nemesis to be reborn. The Ego Gem does not represent an aspect of reality like the others, but is instead the lynchpin that unifies them into a single, omnipotent consciousness. After Nemesis's defeat, the Ego Gem was separated and cast into the Ultraverse, seemingly lost.

The Rhythm Gem (Ultraverse/Malibu Comics)

Another gem, the Rhythm Gem, appeared when the Marvel and Malibu Comics' Ultraverse universes crossed over. Possessed by the vampire lord Rune, its exact powers and origins are nebulous and it is not considered part of the canonical Infinity Gem set in the mainstream Marvel Universe. It is largely seen as a relic of a specific crossover event.

Part 5: Iconic Events & Storylines

The Thanos Quest (1990)

This two-issue miniseries by Jim Starlin is the quintessential prelude to Infinity Gauntlet. The story follows a newly resurrected Thanos as he systematically hunts down the Elders of the Universe who currently possess the Infinity Gems. Through a combination of brute force, cunning, and cosmic chess, Thanos defeats the Champion, the Gardener, the Runner, the Collector, the In-Betweener, and the Grandmaster, assembling the six Gems for the first time and providing the definitive explanation of each Gem's unique power.

The Infinity Gauntlet (1991)

The seminal Marvel cosmic event. Now possessing the complete Infinity Gauntlet, Thanos becomes functionally omnipotent. To win the affection of the cosmic entity Death, he erases half of all living beings in the universe with a simple snap of his fingers. Earth's remaining heroes and the universe's most powerful cosmic beings unite in a desperate, and ultimately futile, assault against the Mad Titan. The story's climax sees Thanos's own hubris lead to his defeat, with the Gauntlet briefly falling into the hands of his tortured “granddaughter,” Nebula, before it is finally claimed by Adam Warlock, who undoes the damage.

Infinity War (1992) & Infinity Crusade (1993)

This two-part sequel explores the aftermath of Warlock's godhood. To safeguard the universe, Warlock expels both the good and evil from his being. This act inadvertently creates two new cosmic entities: the Magus (his evil side) and the Goddess (his good side). In Infinity War, the Magus attempts to seize the Infinity Gauntlet for his own dark purposes. In Infinity Crusade, the Goddess uses her influence to enforce a universal “peace” through brainwashing, forcing the heroes to fight against a twisted form of absolute good. Both events delve deeper into the philosophical implications of the Gems' power.

The Illuminati and the Incursions (New Avengers, 2013-2015)

In a major retcon, it was revealed that Tony Stark had gathered a secret cabal of Marvel's greatest minds—the Illuminati (including himself, Professor X, Black Bolt, Namor, Reed Richards, and Doctor Strange)—years ago. They had secretly collected the Infinity Gems to keep them safe. When they attempted to use the Gauntlet to wish the Gems out of existence, it failed, but the Gauntlet itself was shattered. They divided the Gems amongst themselves for safekeeping. Years later, during the “Incursions” storyline, Captain America re-assembles the Gauntlet and successfully uses it to push away an alternate Earth, saving the 616-universe but shattering the Infinity Gems in the process, rendering them inert for years.

Part 6: Variants and Alternative Versions

Ultimate Universe (Earth-1610)

In the Ultimate Universe, the concept was slightly different. There were at least eight Infinity Gems, not six, and two separate Infinity Gauntlets were required to wield them all. The Gems were scattered across the globe, with one even being embedded in Tony Stark's brain to treat his tumor. A version of Kang and later the villainous Reed Richards (The Maker) attempted to assemble them.

Loki (MCU Series, 2021)

The Disney+ series Loki provided a stunning new context for the Infinity Stones within the MCU. When Loki is captured by the Time Variance Authority (TVA), an organization that exists outside of normal time and space, he discovers a desk drawer full of useless Infinity Stones. The TVA agent Casey reveals that they are so common there that some of the staff use them as paperweights. This powerfully demonstrated that the Infinity Stones, while holding ultimate power within a given timeline, are rendered completely inert in the face of a power that controls the timeline itself.

What If...? (MCU Series, 2021)

The animated series explored several alternate realities involving the Stones. The most significant was a universe where Ultron successfully uploaded his consciousness into Vision's body, claimed the Mind Stone, and then effortlessly killed Thanos to acquire the other five. This Infinity Ultron became a multiversal threat, destroying his own universe and waging war across countless other realities, showcasing the terrifying potential of the Stones in the hands of a being with no restraint.

Notes and Trivia

1) 2) 3) 4) 5)

1)
The original name for the artifacts was “Soul Gems,” with the first one appearing in Marvel Premiere #1 (1972). The name “Infinity Gems” was not established until The Thanos Quest #1 (1990).
2)
The color swap between the comics and the MCU was a deliberate choice by Marvel Studios. The Tesseract (Space Stone) was established as blue in Captain America: The First Avenger (2011), years before a full plan for all the Stones was public. To maintain consistency, the MCU rearranged the other colors. The comics officially adopted the MCU's color scheme in the Marvel Legacy #1 one-shot (2017).
3)
In the comics, the Infinity Gems were thought to have been destroyed during the Incursions saga in New Avengers #3 (2013). They were later found to have been reformed and were scattered across the universe, now much larger in size.
4)
The MCU's requirement of a sacrifice to obtain the Soul Stone on Vormir is a unique creation for the films, adding a personal and tragic cost to Thanos's quest that was not present in the original comic storyline.
5)
The first being to wield all six Infinity Gems in the Earth-616 continuity was not Thanos, but the Elder of the Universe, The Grandmaster, though he was not able to access their full power.
