Quote1 While I possess the Terrigen Mists, I am more important an aide to our High Lord than is Sinister with all his genetic machinations. The Mists are mutagenic, it is how I have the ability to turn my ordinary countrymen into the most extraordinary of creatures. Quote2

Quote1 We're creatures of Terrigen. And Terrigen is poetry, running in our veins. Quote2


The exposure to the Terrigen Mists, or Terrigenesis (sometimes called "T-Gen",[1] Terrigenisis,[2] or Terrigenation)[3] is a process allowing Earth Inhumans to inhale the Mists obtained from the use of the Terrigen Crystals, in order to activate their Inhuman genes and ascend as meta-humans.

Inhumans are "terrigenated",[3] and "undergo"[3] terrigenation or terrigenesis.[3]


Phadion and Rhaya were exiled off the island Attilan for opposing Kadir, along with Tuk,[4] heir of Attilan, possibly their son, and the first offspring of the Inhumans. Tuk lived among the mortals, and his genetic code passed down through generation, increasing the ordinary humans' susceptibility to mutation.[5]

Inhuman geneticist Randac isolated the catalyst for his people about 25,000 years ago,[6] He named the material in crystal form Terrigen.[7] Having taken the work of the Kree, he intended to use it to evolve his people into weapons able to fight back if the Kree returned, creating controversy and dividing his people by his works. Exposing himself to the Mists, Randac became a Godlike-entity,[8] with mental abilities equaling those of the Eternals.[3]

He created a program of voluntary Terrigenesis, which was eventually stopped due to half of the subjects demonstrating nonhuman mutations. This led to the creation of genetic screening before Terrigenesis.[3]




When at the correct temperature and with exposure to water, the crystals react to produce the Terrigen Mists. These vapors are then pumped into a flux chamber during the Terrigenesis process, powering the Inhuman.[7]

Randac's original process was refined and regulated to avoid accidents.[8]

In the last moments of the Silent War, the Terrigen Crystals stolen by Quicksilver and the O*N*E were once again placed into the Terrigen chamber, but Karnak stated that, due to several missing fragments, Terrigenesis would be more unpredictable in the future.[9]

On Earth-1610, Sapphire stood thirteen days and nights before emerging of the Terrigen Mists as Tri-Clops.[10]

Rules and Customs[]

Even among the Inhumans, Terrigenesis is not a common process and not every Inhuman will go through it. In the past, all Inhumans were allowed, producing "radical" and "monstrous" mutations, while damaging the Inhuman gene pool.[7]

In order to stop that genetic loss, every Inhuman had to go through a strict genetic screening before being allowed to go through the transformation. After "many millenia", that strict rule allowed the Inhumans to restore their genetic diversity.[7]

Due to the risk of uncontrolled mutations, the Genetic Council had forbid any humans to go through Terrigenesis and the genetic screening prohibited the Terrigenesis to any Inhuman with human lineage.[7]

As a general rule, Terrigenesis was predominately undertaken by older individuals. Restricted by genetic screenings[7], it was considered as a rite of passage that was not taken by every Inhuman[8]. Inhumans would prepare all their lives to undergo Terrigenesis.[1]

It was the choice of the parents (especially the father)[11] to expose their children to Terrigenesis, or one of the older Inhumans. Most Inhumans go through the mutagenic process.[12]


Richard Schlickeisen's cocoon


During the Terrigenesis process (the exposure to the Terrigen begins), Inhumans will often form a cocoon around themselves,[8] named "Inhuman Terrigenesis Cocoons",[13] "Terrigen Cocoon",[13] "Cocoon of metamorphosis" (by Meruda),[14] or simply "Cocoons".[13]

It seems not all Inhumans or hybrids create a Cocoon:

The time before the cocoon's hatching "is down to matters of just how much Inhuman genetic code a person might possess, and how dominant or recessive it might be, and also to the quantity and purity of the Terrigen that sets off the transformation."[18] Terrigenesis can be incomplete, triggering a cocoon but not result transformation and, in some instances, killing the subject.[19]

Other species, including humans, mutants, and Skrulls have not been shown to form a cocoon, and allegedly, humans don't form a cocoon.[20]

Quote1 Inhuman-kind. When we encounter Terrigen, we change, becoming something other, with new shapes, new gifts that are impossible to predict Quote2

Terrigenesis transformations[]

The process will produce a new gene in the Inhuman genetic settings,[21] or triggered latent mutant genes,[22] Inhuman genome[19] or Inhuman gene[23] granting him powers and/or a new appearance, with results impossible to predict.[19]

A belief of the Inhumans is that the Terrigenesis revealed the true nature of the beings who go through it.[24]

Quote1 Does the Terrigen respond to the environment? Is there a chemical intelligence inside Terrigen? Quote2
Dr. June Covington[src]
Quote1 Terrigenesis works interactively. It gives you what you most desire. Or conversely, what you most fear. There is anecdotal evidence that some Inhumans emerge from the Mists as their worst nightmare. Quote2
Professor Cartwright[src]

It has also been theorized that Terrigenesis responds to the needs, fears, or desires of the Inhuman as individuals or a nation;

  • Geneticist Ultarnt proposed that Terregenesis was related to the needs of the Inhumans. After studying the seemingly random transformations she realised the mists altered the Inhumans to adapt to the needs of the group, conflict lead to more aggressive mutations. However, this discovery was deemed too great for the Inhumans and it's secret was hidden with only a handful like Karnak knowing this.[25]
  • During the Silent War, Professor Cartwright stated that the Terrigenesis acted to give the subject his most desired or most feared thought. Just as Cartwright, who desired to be like his idol Captain America, was given muscular form. In this way he theorized that some control over the process was possible in order to influence Terrigenesis.[26]
    • He furthermore stated that the Secondary Terrigenesis was even more risky.[26]
  • During the War of Kings, Karnak stated that the high number of aquatic mutations among the new Inhumans was possibly an anticipation of the Terrigen Mists, to provide for the needs of soldiers to be effective in zero-gravity environment in a predominately space based conflict.[citation needed]
  • Later, during the release of the Terrigen Bomb on Earth, other cases hinted towards theories of correlation on the individual scale:
    • June Covington stated that Richard Schlickeisen's mutation, an invisibility to the machines, was "a magnificent enhancement for the 21st century", because of the global electronical surveillance, and postulated that the Terrigen was sentient and receptive to the environment.[21]
    • Joey Nobili developed light-drawing abilities allowing to reproduce complex drawings, while he never managed to draw correctly what he imagined before.[27]
  • It is said that Inhumans are often born to serve a specific purpose.[28]

Similarly, during the Evolutionaries' attacks on non-strictly human types, Sun Girl considered that the appearance of Nuhuman Mark Sim and his energy-absorption was no coincidence.[29]

On Earth-199999, it is the belief of the Inhumans who live at Afterlife that the Terrigen mists give an individual their abilities to serve a particular purpose. For example, the Inhuman known as Lash was given abilities that were perfectly able to counter those of Hive, another Inhuman. However, it is also implied that an Inhuman's abilities are purely random, as their Kree creators view them as "failed experiments."[30][31][32][33]

On Earth-1610, it was stated "the abilities granted inside [the Terrigen Mists] are entirely dependent of nature's whims".[10]

Comparatively, Doctor Lucius Kleinstein supposed correlations between personality and the mutations among the mutants.[34] Also related, the Gamma Mutates themselves allegedly obtain physical transformation matching their subconscious.[35]

Reproduction of other species features[]

Another statement (from Kree Accuser Ronan) was that the Inhumans had been molded after other species:[36]

As part of an authorized experiment, Timberius was mutated using plant DNA and Terrigen, turning him in a plant-like Inhuman with botanopathic abilities.[3]


There is an hereditary transmission of terrigenated attributes: The Inhumans are often born with characteristics from their parents, but frequently are strictly human in appearance also.[12]

A few relations have been witnessed, some of those relations being free of the Terrigenesis process:

  • Stallior and his family were stated to have all obtained their centaur-like bodies thanks to the "hereditary transfer of Terrigenated attributes from ten generations",[3] hinting that there maybe and/or sometimes is a moment when Terrigenesis gifts set themselves into the genetic make-up and is transmitted through birth.
  • Lockjaw's grandpup from the future Puppy inherited his grandfather's teleportation, but could also travel across time.[38]
  • The Bird People were hereditary winged Inhumans, who eventually split.[39]
  • The tribe that would spawn the Hidden Ones were gifted with the same "persuasion" powers, along with the same appearance,[40] but were also granted with individual powers and mutated fake visual appearance.[41]

Others are presumably more or less tied to Terrigenesis:

It is unclear if there is a hereditary impact concerning the Terrigenesis mutations.

Gorgon Petragon (Earth-616) from Silent War Vol 1 1 001

Gorgon after Secondary Terrigenesis

Secondary Terrigenesis[]

Quote1 If there were any justice, secondary Terrigenesis would devolve you into a puddle of protoplasmic slime! Quote2
Professor Cartwright to Gorgon[src]

Passing twice through the Terrigen Mists, named Secondary Terrigenesis,[17][44] is seemingly a dangerous procedure. It was first alleged that it was never performed by the Inhumans,[17] but was revealed as quite an uncommon occurrence.[26]

Under the rule of Gral, successive exposure to the Terrigen were stated to further the extent of mutations.[45]

Professor Cartwright subjected Gorgon to the mists, developing further his animalistic mutation.[17]

He also stated that the Secondary Terrigenesis was more risky as the Terrigen transformation was prone to pervert the initial transformation.[26]

At the last moments of the Silent War, Carthus of the Genetic Council asked for Black Bolt to began a program of compulsory Terrigenesis and Secondary Terrigenesis, to produce a massive army to counter the USA, but those propositions were rejected by Karnak, as the Secondary Terrigenesis was too disastrous.[9]

Also see the Secondary Mutation, a process occurring among the mutants.

Terrigen Bomb[]

While not stated to be a Secondary Terrigenesis, Black Bolt's exposure to the Terrigen Bomb weakened him,[citation needed] until he recovered in a bath of exogenetically charged waters.[46]


Later, the Nuhuman Quickfire was exposed by Jason Quantrell to what he called "kind of Secondary Terrigenesis, an upgrade", trapping her into some sort of red, translucid, flexible, allegedly hard-to-break-through cocoon in which she was still awake.[44]

Effects by species and processes[]

Terrigenesis from Son of M Vol 1 2 0001

Terrigenesis fail on an Inhuman


The Inhumans, who went through Terrigenesis, demonstrated a nearly unlimited diversity of powers and mutations as the mutants or the Warpies.


According to the Dark Rider, Inhumans with two distinct forms are rare, making Devlor[47] an Inhuman mutant.[48]

On Earth-199999, Andrew Garner was also gifted with abilities that resembled shapeshifting.[49] Garner spent periods of time between his pre-Terrigenesis form where he exhibited no Inhuman abilities and a monstrous persona known as "Lash" which showed a complete physical transformation and had energy-based abilities. The reason for this transformation is that he emerged from his Terrigenesis cocoon before he had fully transitioned into his Inhuman form. Once this transition was complete, the Lash persona apparently took over with no possible return to his human form.[31] That ability to shift between human and Inhuman form was considered as unique.[50]

Non-human mutations[]

The development of "radically non-human mutations" is seen as a bad Terrigenesis result,[45] and occurred in numerous occasions:

  • Under the reign of Randac, half of the voluntary subjects were affected by such results.[45]
  • Under the reign of Gral, the whole population was forced to undergo Terrigenesis, with three quarters of the population being turned into "non-humanoid types".[45]


It was intended that many Inhumans that went through the Mists never came back.[51]

Petras Petragon (Earth-616) from Inhumanity Vol 1 1 001

Petras's mutation


The last Attilan Inhuman to have gone through the Terrigenesis was Petras Petragon, the nine year-old son to Gorgon. The process turned him in a minotaur-like creature, as an example of the failure of the Terrigenesis,[8] and later in an human form requiring life support to survive.[52]

Terrigenesis from Secret Invasion Inhumans Vol 1 3 0001

Rynda exposing her fetus to the Mists


Black Bolt was exposed while in the womb to the Terrigen Mist as an experiment of his parents, Agon and Rynda. That experiment concluded with the birth of one of the most powerful Inhumans ever.[53]


According to the Dark Rider, the shapeshifter Devlor was the only case of an Inhuman with two distinct forms, supposing that Devlor was different among his own kind[47] and making him a mutant.[48]

He was indeed considered as having an unstable Terrigen-enhanced form, to not be a true Inhuman and called him a "cripple" and a "deviate-changeling".[54]


Theoretically, Terrigenesis is authorized only for pure Inhumans and is denied to any descendant of humans.[7] However, there are a few cases of Inhuman hybrids known to have undergone Terrigenesis.


On Earth-616, the Inhuman/Deviant hybrid Maelstrom did at some point undergo Terrigenesis.[55][56] It is seemingly unlikely that the Deviant/Inhuman hybrid Ransak underwent Terrigenesis.[citation needed]

On Earth-9997, Ransak didn't demonstrate any powers due to the Terrigen Mists released in Earth atmosphere.[citation needed]

A case of a Deviant (due to his Deviant syndrome mutation) who went through Terrigenesis would be Thane, son of Thanos, described in the section about the Inhuman/Eternal (Deviant Mutants) hybrids.

Eternals (Deviant Mutants)[]

Following the detonation of the Terrigen Bomb, Thane, son of Thanos' legacy was activated, revealing his lineage and its relation with Death,[24] presumably along with the Deviant syndrome mutation of his father.


While the Genetic Council and the genetic screening prohibited the Terrigenesis to any Inhuman with human lineage,[7] there have been many Inhuman descendants revealed through Terrigenesis:

Using a Terrigen Bomb, a cloud of Terrigen Mist (also known as T-Cloud)[57] was released by Black Bolt on Earth's atmosphere when Thanos invaded Attilan.[58] Its resulting propagation around the world affected all humans with Inhuman ancestry (originated from the dissemination of some lost tribes among the early human populations),[16] causing them to undergo "wild Terrigenesis" (as called by Karnak),[8] a process that consisted of the formation of a cocoon around them, which would then hatch after a variable period of time. The cocoon could open immediately after forming, or days later.[59] The resulting superpowered individuals from this event became known as "NuHumans,"[1][59] "Attilans" (on human social networks),[60] and "Changelings" (by Chinese soldiers).[59]

Also see the List of NuHumans activated by the Terrigen Bomb.

Also humans from their mutant side, the Inhuman/mutants hybrids may have differences in their Terrigenesis reactions.


Luna, born from the mutant Quicksilver and the Inhuman Crystal, was tested by Reed Richards who stated that her mutant and inhuman genes had cancelled each other out and she was technically human.[61] She was consequently denied the Terrigenesis[7] by the Genetic Council.[62]

At age six,[7] she was exposed to the Terrigen Mists by Quicksilver[62] and was granted with empathy, short-term precognition (or anticipation) by aura[63] visualization,[64] and later empathic manipulation, but suffered both dependency[65] and loss of control from her powers, requiring her to wear shades.[64] She also developed a psychic link with the Mists,[66] and suffered migraines from it.[63]

With the High Evolutionary claiming that Quicksilver isn't a mutant, but a mutate "masquerading" as a mutant,[67] Luna's status as a mutant/Inhuman hybrid has been cast in doubt. But, there are examples of mutant/Inhuman hybrids that have survived, and even thrived, like Talogan of Earth-691 and alternate reality versions of Luna Maximoff, but that can be explained away by the fact that mutant biology can vary from reality to reality.

Ms. Marvel was revealed to have both Inhuman and mutant genes and gained different powers from each side of her heritage. Due to Ms. Marvel undergoing Terrigenesis before her mutant powers could manifest, Charles Xavier believed that this was why she was not inflicted with M-Pox when exposed Terrigen Mist.[68]

Other Homo species[]

The Terrigen Mists were stated to be potent enough to cause any living organism to mutate from exposure to it.[69]


A case of human (technically human due to her Inhuman and mutant genes cancelling each other) went through Terrigenesis would be Luna, described in the section about the Inhuman/Mutant hybrids.

The Mists released from the Terrigen Bomb don't seem to have affected the base-line humans: Karnak stated that the Bomb didn't release Terrigen Mists, when Hank McCoy confirmed that all data suggested that the Mists were toxic to humans.[8]

Dr. Hydro, using the Terrigen Mists (possibly acquired from Maesltrom and/or Phaeder), mutated his followers into green skinned scaly amphibians known as the Hydro-Men. They were all depowered by Reed Richards using an Anti-Terrigen Compound.[70]

Quote1 The human body cannot withstand Terrigenesis Quote2
Professor Cartwright[src]
Quote1 The process of Terrigenesis is lethal to humans. Within days or weeks of undergoing the process, you will die. Quote2
Maria Hill to U.S. Marines volunteers[src]

Professor Cartwright, who was exposed to the mists and developed a strong musculature, caused the President of United States to order more experiments on humans, calling for U.S. Marines volunteers.[63] The Terrigenesis gave him what he most desired: a peak human body like Captain America, but was condemned to die soon after his transformation, his body quickly decaying.[63][26][71]

Quote1 The Mists of Terrigen have worked their alchemy on human and Inhuman alike, shaping creatures of terrible beauty, with the ability to inflict pain in more ways than could be imagined. Quote2

A dozen U.S. Marines willingly subjected themselves to Terrigenesis, after which they developed powerful mutations, but condemned themselves as well.[71][9]

Such Terrigenesis were accompanied with side effects: "Dizzy spells, nausea, itchy scalp"[63] at first, but eventually death in days or weeks,[26] as their body decayed as with Cartwright's physical mutations[71] and head implosion of a psionic Marine.[9]

In a rare cases, "pure humans" (as far as we know) exposed to Terrigen Mists were able to develop powers without dying, though the powers revealed were unstable:

  • Crossbones developed the ability to fire energy blasts from his face and later lost this power.[72]
  • Aamir Khan was ostensibly exposed to Terrigen mists and developed the ability of blasting psychic force fields around himself, but quickly blacked out.[20] However, it remains unclear both if Aamir was really a pure human or an Inhuman descendant, and if the gas he inhaled was pure Terrigen or not.

In Earth-199999, humans with no Inhuman lineage were unaffected by pure Terrigen. Attempts to make artificial Terrigen crystals and mists, however, often had devastating effects on humans.

  • Jiaying and the Inhuman community at Afterlife synthesized Terrigen crystals from devices known as Diviners. These crystals were contaminated with the Diviner metal, which was lethal to humans. Anyone with no Inhuman lineage would be petrified if they were exposed to the mists produced by these crystals.[73][74]
  • Holden Radcliffe's attempts to replicate the Kree experiments that created the original Inhumans for Hive resulted in the creation of Primitive Inhumans. These Primitives were gifted with enhanced physical abilities, but were grotesquely transformed and had diminished cognitive abilities.[33]


It was stated that the gene changing the Inhumans was the same that the one having triggered the mutation in the human population, turning them into mutants.[75]

Also humans, the mutants may have differences in their Terrigenesis reactions.

Alpha Primitives[]

While exposing themselves to a high dose of Terrigen Mist ("a mist concentration than any Inhuman has ever dared"), three leaders of an Alpha Primitives riot transformed into an entity composed of three spheroid forms emitting an aura of mental energy, the Trikon.[76]

The Alpha Primitives who would become the Trikon knew that they were risking death in the process.[76]


Because of their human lineage, mutants are supposed to be kept away from the Terrigenesis.[7]

Depowered Mutants[]

Quicksilver,[7][77][78][26] and Beast,[79] both inspired by divine visions, asked Black Bolt and Medusa to be allowed to use the Terrigen Mists to reverse the effects on the mutants depowered by the M-Day event.[64] Both demands were denied due to the necessity of a genetic screening and the rule forbidding humans or human descendants from undergoing Terrigenesis[7] and that Terrigenesis would only bring harm to mutants.[79]

Quicksilver believed that the Terrigen Crystals had chosen him[78][26] and viewed the M-Day event as a divine test. He believed that Terrigenesis would only work on mutants who were worthy.[77]

Such Terrigenesis was accompanied with similar side effects as other humans, with at least being "Dizzy feelings",[64] but the transformed mutants were either depowered without further harm, other than their lack of control of their power,[80] or exploded from the energies within themselves.[81]

Direct exposure - Mist Inhalations[]

The Mists were indeed able to restore the mutants powers of depowered mutants, but at higher and uncontrollable levels:

The first dose of Mists had to be inhaled and took a few minutes before becoming effective.[65]

It was believed that for their powers to be fully restored, the mutants had to repeatedly expose themselves to the Mists,[62][64][65] Through repeated inhalations of the Mists, Quicksilver absorbed the properties of the Terrigen Mists,[82][83][78] having his hands[80] and chest[81] encrusted with Terrigen Crystals.

Eventually, the effects of the mists faded naturally.[80]

Direct exposure - Quicksilver's Terrigenesis power[]

Quicksilver then absorbed the properties of the Terrigen Mists,[82][83][78] by piercing his flesh with the Terrigen Crystals after six days and nights of exposure to the Mists.[78]

Using the Terrigen Crystals encrusted in his hands, he was able restore Reaper powers in mere seconds by touching him.[80]

Those repowered mutants were short-lived,[82] save for Reaper who wasn't on the way of explosion until "channeled-exposed" repowered mutants started to get lose themselves.[81]

Channeled exposure[]

Stating that Rictor had a connection to nature due to his former powers, Quicksilver asked him to help him repower the mutants by channeling the process, as the evolution stems from nature.[85]

Those powers were seemingly effective and controlled, but in fact unstable, and the bodies were quickly overwhelmed by the energies, and exploded.[81]

While Elijah Cross exploded,[81] Abyss retreated into his Brimstone Dimension with Fatale and Abyss, freezing their state, before they would be extracted from that dimension by Terrance Hoffman, and their energies were drag out, allowing them to live with their mutant appearances, but depowered.[86]

Active Mutants[]

Quicksilver also used the Terrigen Crystals on active mutants, with deleterious effects.

He first used those as a way to threaten Strong Guy, stating that he didn't knew if nothing would happen, or if an active mutant would explode.[83] He later theorized after had tried that the restorative properties of the Terrigen Mists would cause a cellular feedback.[87]

When Quicksilver tried to harm Layla Miller with Terrigen Crystals, she wasn't affected, and he stated she wasn't a mutant.[81] It is possible that would be related with her unclear mutant status.

The Terrigen Mists released into the atmosphere by the T-Bomb were proved to kill the mutants slowly, gradually incapacitating them. Additionally, all mutants were sterilized by the so-called Terrigen Plague.[88]

  • As an example, Rogue was especially sensitive to the effects of Terrigen mists on their mutant physiology, exhibiting first skin rashes,[89] eventually requiring life support.[90]

On Earth-295, Maximus intended to use the Terrigen Mists to mutate the X-Men, granting them freaks appearances while allowing him to mold them.[91]

Other Earthlings species[]

O*N*E Professor Cartwright stated that he had used the Terrigen Mists on "animal subjects, with somewhat mixed results".[17]

Apes: The Insimians[]


Alien species[]



Maximus was tasked with the mission to adapt the Mist for the Kree evolution to start again, but he found out that the Mist weren't of any help for them, as no mutation occurred.[citation needed]

On Earth-200080, the Kree were seemingly affected by the Terrigen Rains, and were able to develop thanks to those mutations, upgrading their genetic core,[92] but the exact details are unknown.

Terrigenesis from Secret Invasion Inhumans Vol 1 2 0001

Skrull through repeated Terrigenesis


The Skrulls have been proved to be sensible to the Mist: During the Secret Invasion, Medusa tortured a Skrull by throwing him into the Mist repeatedly, developing random mutations along with great sufferance. Among the mutations were a furred gorilla-like arm, the other being turned into a snake-like being seemingly autonomous, and also an additional face with glowing eyes on the side of the head.[93]

It was stated by Finesse that the Mists didn't worked as power bestowal substance on the Skrulls, and that the supposed Skrull who impersonated Quicksilver's after M-Day (Pietro's lie) shouldn't had "regained his lost mutant powers" by using Terrigen Mists.[94]


Other processes have been proved to replace Terrigenesis in order to activate Inhuman powers.

Human Torch's presence[]

For some reason, Human Torch was able to activate the recessive Inhuman gene of Toro, who was thought for years to be a mutant.[95]

Amphogen and Antigen Tree from Fantastic Four Vol 1 577 0001

Amphogen water & Antigen Tree

Hyde Formula[]


Similar processes[]


The Kree experiments and technology has allowed other processes,[96] similar to the Terrigenesis, to be achieved on over a hundred worlds,[97] according to the Supreme Intelligence's Metagenesis plan. All species tested were successes, reacting to specific race-based catalysts.[98]

All species of the Universal Inhumans,[99] save for five tribes were slaughtered by the Kree Accusers Corps.[98]

Amphogenesis & Amphogen[]

The Amphogenesis was used to power the Moord (Inhuman Badoon).

It consists of a drop of the "irreplaceable diluted water from the dormant Amphogen" (it is unclear if it was absorbed or simply dropped on).[96]

Antigenesis & Antigen Tree[]

The Antigenesis was used to power the Inhuman Kymellians.

It consists of the consumption of the nectar of blooms of Antigen Tree.[96]

Isogen Orbs and Exogen Spice from Fantastic Four Vol 1 577 0001

Isogen Orbs & Exogen Spice

Exogenesis & the Exogen Spice[]

The Exogenesis was used to power the Inhuman Dire Wraiths.

It consists of the inhalation of the Exogen Spice,[96] using an instrument similar to a hookah.

After being strongly weakened by the detonation of the Terrigen Bomb, Black Bolt recovered from that power loss thanks to a bath in exogenetically charged waters from Maximus.[46]

Isogenesis & Isogen Orbs[]

The Isogenesis was used to power the Inhuman Centaurians.

It consists of the injection of the extract of the Isogen Orbs.[96]

Xerogenesis & the Xerogen Crystals[]

Using the Kree device Slave Engine, and empowering the Xerogen Crystals, or Xerigen Crystals,[100] the Inhumans were able to turn human in other creatures, the Alpha Primitives, by making them inhale the Xerogen Mists.[101]

The origin of the Xerogenesis is unknown, and it is not known either if it is part of the Metagenesis experiments.
