The Terrigen Mist is a fictional substance in stories published by Marvel Comics, particularly those that feature the Inhumans, a fictional race of superhumans. The Terrigen Mists were first referenced in the Fantastic Four comic book series.[volume & issue needed]


The Terrigen Mist is a natural mutagen, arising as a vapor from the Terrigen Crystals, which are able to alter Inhuman biology. The Mists were discovered by the Inhuman geneticist Randac approximately 25,000 years ago. He immersed himself in the Mists and gained mental powers comparable to the Eternals.[1] Sometimes the mutated subjects gain superhuman abilities; Medusa, Black Bolt, and Kamala Khan are three examples of this.

However, in the past, uncontrolled exposure to the Mists (due in part to Randac wishing for all the Inhumans to undergo Terrigen treatment or Terrigenesis) mutated the majority of the Inhuman population into hideously deformed monsters. After centuries of eugenics and birth control, the Inhumans managed to mitigate the genetic damage and cultivated a more responsible use of the Terrigen Mists. The practice they developed was to let only genetically perfect specimens undergo the random mutations provoked by the Mists. Their theory was that genetic screening could avoid the risk of hideous and animal mutations in an individual. However, there are examples throughout the Inhumans' canon where an exposed Inhuman became a devolved, sometimes mindless, evolutionarily inferior throw-back. The term Alpha Primitives was coined for these unfortunate outcasts of Inhuman society, who would for centuries become the breeding stock of a slave race. Resentment at this caste system sometimes bubbles up, and the Alpha Primitives have tried to overthrow their rulers in multiple storylines, often as a result of manipulation by a third party.


Use by non-Inhumans

Since the introduction of the Terrigen Mists, the inhabitants of the Marvel Comics universe have believed that Terrigen Mists were toxic for regular Homo sapiens. When the depowered mutant Quicksilver subjected himself to the Mist, he gained the ability to travel through time as an acute enhancement to his former super-speed. Luna, Quicksilver's half-human half-inhuman daughter, gains psychic abilities from the Mists allowing her to see emotional auras emanating from individuals.

It is also shown in this series that depowered mutants, if exposed to the Terrigen Mists, gain an uncontrollable version of their former powers. For example, the Mists restore the hyperacute senses of Callisto, but all the amplified stimuli cause her to fall into a coma. However, the effect is only temporary as powers fade after a short while. At the end of the Son of M series, the U.S. government confiscates the Terrigen Crystals dropped by Quicksilver, which leads Black Bolt to declare war on the United States.

Use in the 'Silent War'

Use on X-Cell depowered mutants provided moments of renewed powers but then caused them to explode. Use on U.S. Marines in Silent War also proved that the mists, while providing temporary powers to humans who are certain in their purpose, also causes certain death. The Inhuman Gorgon was subjected to a second exposure while imprisoned, which increased his strength, but possibly lowered his intellect.[2]

The Inhumans have introduced the Terrigen Mists to the Kree to further their evolution. Also, they have planned on using the Utterance of Destiny, or the T-Bomb, which would spread the Mists all across the universe, making all living beings Inhumans, which to the prime group, would bring about equality and an end to war.

Use in Infinity and Inhumanity

During the end of the "Infinity" storyline, the Terrigen Bomb was detonated in Earth's atmosphere during the Inhumans' fight with Thanos. This caused anyone who was a descendant of an Inhuman to develop powers of their own.[3]

Xerogen Mist

The Kree left the Inhumans the Xerogen Crystals to use as a defense against the growing numbers of their human cousins. Whereas the Terrigen Mists enhance Inhumans with superpowers, the Xerogen Mists de-evolve humans into Alpha Primitives through a state of Xerogenesis. The deposed Inhuman King called the Unspoken removed the crystals from Attilan. But when he was banished, he cultivated and grew the Xerogen Crystals.[4]

The Mighty Avengers battled and defeated the Unspoken and the Xerogen crystals were returned to the Inhumans by Quicksilver. Queen Medusa quickly claimed that the Xerogen Crystals do not exist.

Relations to Terrigenesis

When the Universal Inhumans were being developed, there were different methods to different aliens that were similar to the Terrigenesis.

Amphogenesis is the process of injecting one drop of the diluted water from the dormant Amphogen (a mutagenic substance) that gives the Badoon members of the Universal Inhumans their powers.[5]

Antigenesis is the process of consuming the nectar that blooms from the Antigen Tree (a mutagenic substance) that gives the Kymellian members of the Universal Inhumans their powers.[5]

Exogenesis is the process of inhaling the Exogen Spice (a mutagenic substance) that gives the Dire Wraith members of the Universal Inhumans their powers.[5]

Isogenesis is the process of injecting the extract of the Isogen Orbs (a mutagenic substance) that gives the Centaurian members of the Universal Inhumans their powers.[5]

  • Throughout the second season of Agents of S.H.I.E.L.D., both S.H.I.E.L.D. and Hydra battle for possession of a mysterious obelisk that was found with a Kree corpse during World War II. It is eventually revealed to be called the "Diviner", a Kree artifact which would petrify anyone without Inhuman potential. In the episode "What They Become", the Diviner is brought to an underground Kree city to be activated, where it opens to reveal a Terrigen crystal and releases a small burst of Terrigen Mist, which causes Skye and Raina to undergo Terrigenesis.[6] In the episode "Aftershock," Terrigenesis causes Daisy "Skye" Johnson (Chloe Bennet) to develop earthquake-based abilities and gave Raina (Ruth Negga) a thorn-covered appearance. In the episode "Who You Really Are," a Kree warrior tells S.H.I.E.L.D. that the Inhumans were one of several experiments carried out by a rogue faction of Kree and that the Diviners contained Terrigen Crystals used for the Terrigenesis. In the episode "Scars", the Inhuman leader Jiaying (Dichen Lachman) reveals that the Inhumans can now artificially grow Terrigen Crystals on their own, but these new crystals are laced with Diviner metal, making them harmless to Inhumans but lethal to humans.
