There exists a toxic mutagen called the Exo-gene (also referred to as the Exogene). For example, Superman and Wonder Woman were categorized as Alpha-level, while Metamorpho was considered a Beta.

There are roughly 1.3 million metahumans on Earth, 99.5% of which are considered “nuisance-level” (such as kids who can bend spoons with their mind and the old lady “who keeps hitting at Powerball”).The other 0.5% are what Checkmate and the O.M.A.C.s consider Alpha- and Beta-level threats. Superman and Martian Manhunter (aliens) as well as Wonder Woman (a near-goddess) and Aquaman (an Atlantean) are referred to in many instances as “metahumans.” It can refer to anyone with extranormal powers, no matter the origins and including those not born with such power. The terms “meta” and “metahuman” do not only refer to humans born with biological variants. And from that time onward, the Sons of Vulcan passed the metavirus down in an unbroken line, sworn to hunt and kill White Martians. This metavirus was responsible for the empowerment of the very first Son of Vulcan. The White Martians also created a metavirus, a metagene that could be passed from host to host via touch. As punishment for this, the group of renegades known as the Hyperclan was exiled to the Still Zone, a version of the Phantom Zone. Whereas before evolution would have eventually made mankind into a race of superhumans similar to the Daxamites and Kryptonians, now only a select few humans would be able to develop metahuman powers. Due to their experimentations, they actually altered the destiny of the human race. The White Martians performed experiments on these primitive humans, changing the metagene. The genetic potential for a future metagene was discovered in ancient human DNA by the White Martian race. Other metahumans may also experience a minor to radical alteration in physical appearance from the human norm-wings, gills, a tail, fur, altered skin-color, etc. Examples of powers shared by many individuals include telepathy, telekinesis, flight, the ability to project energy, accelerated healing and enhanced physical strength, agility, or senses-all to variable limits. Some metahumans may be born with incredible and incomprehensible powers and abilities. However, Dinah Laurel was born with a metagene, from which her famed ultrasonic scream, known as the Canary Cry, developed. Although her mother (Dinah Drake Lance, the original Black Canary) was a superhero, neither she nor her husband Larry Lance were born with any known metagenes. One well-known example involves Dinah Laurel Lance, the second Black Canary. There are also people born with superhuman abilities, suggesting the metagene can activate spontaneously and without any prior appearance in the ancestry. This gene often lay dormant until a moment of extraordinary physiological stress activated it, and upon activation it would use the source of the biostress as a catalyst for “genetic change,” resulting in metahuman abilities. One of the Dominators discovered that some humans had a “biological variant” he called the meta-gene (also spelled “metagene”). Sometimes possession of the Meta-Gene enables human beings to survive what would otherwise be considered fatal circumstances, thereby allowing external forces to prompt a physiological change which may generate super-powers The Metagene Possession of a Meta-Gene does not automatically equate to an individual being gifted with super-powers however.

This extra gene is referred to as the Meta-Gene. Metahumans possess an extra gene in their biological structure, which is commonly responsible for the genesis of latent super-powers. Metahumans, by definition, are indiginous to the planet Earth, and make up a signficant portion of the planet’s super-hero and villain community. So, “metahuman” simply describes persons and/or abilities beyond normal human limits. The prefix meta-, in this context, simply means “beyond”-as in metastable, which is “beyond regular stability ready to collapse at the slightest disruption”, or metamorphosis, which is “the state of going beyond a single shape”. Metahumans: A term coined by the alien Dominators, and used to describe any human being with what are commonly described as “super powers”. Some Metahumans may generate unusual physical characteristics, such as animalistic features, or increased size, etc.
