well i remember him as the character rather the the actor that whay I said I had trouble remember his name, but not his powers but yes death bolt's actor was Doug jones
and yeah he was killed by snart

the nazi guy one second his name is baron Von

Meta-human
[FONT="]Meta[/FONT][FONT="]-[/FONT][FONT="]human[/FONT][FONT="]s, shortened as [/FONT][FONT="]meta[/FONT][FONT="]s, and often referred to as super[/FONT][FONT="]human[/FONT][FONT="]s, are individuals who acquired powers and abilities unlike those of normal [/FONT][FONT="]human[/FONT][FONT="]s after experiencing mutation of their bodies (in comparison to magic users, who learned how to[/FONT]
[FONT="]harness primordial energies without being mutated themselves). Most obtained their powers after surviving an explosion caused by a malfunction of the S.T.A.R. Labs particle accelerator on December 11, 2013. These people were exposed to the particles and dark matter that altered their genetic, chemical, or even atomic structure, giving them a variety of abilities. Their abilities seem to often relate to what energy or matter the future superhumans were directly in contact with at the time of exposure.[/FONT]
[FONT="]On Earth Two, intending to prevent the negative effects of the particle accelerator, Dr. Harrison Wells of that universe allowed excess radiation to flow underground, with the first meta-human appearing 11 hours following.[1]

Overview
[FONT="]Meta-humans are represented by a wide spectrum of mutated people, with mental state, physical appearance and physiological specifics unique for each individual. The conditions they were in during the exposure to the mutative element seem to affect how the mutation changes a person. Furthermore, there are dormant meta-humans, like Henry Hewitt and Jefferson Jackson, whose powers did not resurface until the connection to Firestorm Matrix, which either re-enabled their mutative physiology, or represented a new mutation altogether.[2][/FONT]
[FONT="]Most meta-humans seen on Earth One and Earth Two mutated after exposure to dark matter connected to the S.T.A.R. Labs particle accelerator. Some meta-humans acquired their powers through other means, not directly related to being hit by the wave of dark energy after the particle accelerator explosion. Among such meta-humans are Eliza Harmon (used Velocity serums to give herself superhuman speed, although she may have been a dormant meta-human prior to that), Valentina Vostok (used the Operation Svarog version of Firestorm Matrix to become a Soviet Firestorm) and Jake Simmons (source of mutation unknown). Through unknown means, meta-humans of Earth Nineteen and Earth Three also acquired powers. In other universes, like Earth Thirty-Eight, humans would mutate as part of an accident without any dark matter involved, like what happened with Livewire. There's a middle-ground case regarding advanced cyborgs, like Metallo: while mostly enhanced by cybernetics, Metallos were mutated on some level, surviving despite their bodies being filled with Kryptoniteenergy, and requiring the Kryptonite "heart" to function properly.[/FONT]
[FONT="]It is arguable whether those affected by the Mirakuru drug can be considered true meta-humans. On the one hand, their case is similar to that of Eliza Harmon, who amplified herself with the Velocity drug, receiving meta-human powers at the cost of negative effects for sanity. On the other hand, their condition is reversible, as a Mirakuru cure was created, that allowed to cure Slade Wilson and Roy Harper. However, the Flash's meta-human powers were also taken away from him when Hunter Zolomon stole his speed, turning him into a normal human once again. Additionally, Slade Wilson was affected by the Mirakuru for years, implying that he would retain his superhuman abilities if not for the cure. One way or another, Barry Allen researched the case of Cyrus Gold, a Mirakuru-affected member of the Church of Blood as part of his hunt for "the impossible", which otherwise included meta-humans.[3][/FONT]
[FONT="]Some meta-humans consider themselves separate, or at least different enough from the regular humans to identify as something else. The prime example of such thinking would be members of Zoom's meta-human group, who ushered in the Metapocalypse upon Central City. In the speech before his followers, Zoom depicted humans as the archetypal "Other", claiming that they think that Earth One belongs just to them, and inciting the meta-humans under his command to take over this world. Characteristically of this group, Killer Frost, Black Siren, King Shark and Reverb were all shown preferring to refer to themselves with their meta-human "names", instead of their original ones. Interestingly, Hunter Zolomon himself preferred to be called by the name of the man whose identity he stole, Jay Garrick, rather than his own meta-human nickname, or especially his real name, as shown when Caitlin Snow called him "Hunter", causing Zolomon to relive a painful traumatic flashback.[4][/FONT]
[FONT="]Meta-humans are not to be confused with magic users, like Damien Darhk or John Constantine, who receive their powers not thanks to mutation, but by manipulating primordial energies of the universe, such as Light of the Soul. However, it is possible for an individual to exhibit both magic powers and abilities related to mutated physiology, Vandal Savage being a prime example of such.[5][6][/FONT]

umm the arrow verse isn't that developed on the meta gene thing . the books and the video game explanations and dc animated are however.
examples like the game DCuniverse online

Metagene
[FONT="]During their attempted invasion of Earth, the Dominators discovered that some humans had a "biological variant" they called the "Metagene". Scientifically defined as the genetic source of an Earth-born metahuman's "super abilities", this gene often lies dormant within an individual 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. However, examples have also arisen where individuals are born with their metagene already active or their metagene suddenly becomes active later in life with no apparent instigation.
It is possible for individuals skilled in science and biology to manipulate, dampen or modify the activities of the metagene: while the Dominators were able to devise a "Gene Bomb" able to accelerate the metagene activity to the point of cellular and physical instabilities, Earth scientists have been able to create devices that can also repress the metagene; enabling a metahuman to be incarcerated in a prison facility.[/FONT]
[FONT="]The origin of the metagene can be traced back to the alien overlord Lord Vimana of the Vimanian alien race who, over 3 million years ago, in an effort to create a race of super powered slaves for their empire, forced their worker drones to mate with humanity's ancestors
Australopithecus afarensis (3 million years ago), and later
Homo erectus (1.5 million years ago). While it is unknown what became of the Vimanians, the genetic potential of the metagene was discovered in
Homo sapiens (500,000 - 250,000 years ago) by the White Martian race. The White Martians performed experiments on these primitive humans and changed how the metahuman phenotype was expressed by the metagene. Due to their experimentations, the White Martians altered the destiny of the human race. 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. As punishment for this, the group of renegades known as the Hyperclan was exiled to the Still Zone, a version of the
Phantom Zone.[/FONT]
[FONT="]In modern day, in response to the witnessed power that metahumans exhibited in the battlefield during World War II, various countries have started up "Metahuman Programs" with the aim to create metahuman soldiers or weapons through the manipulation of the metagene to use for various purposes.
Focusing on the
United States of America, their Metahuman Program began with the development of serums and chemical science in an effort to chemically enhance subjects beyond typical human levels (
Deathstroke's origins stem from these proceedures). The nation's focus would later move on to the usage of atomic power and alien technology to enhance their subjects; one infamous instance of this focus was the Atom Project, wherein the military fused a subject with atomic energy before containing them within an nigh-indestructible shell of alien alloy (
Captain Atom and
Major Force originate from the Atom Project). Since the
Lex Luthor Presidency, the United States' metahuman programs have turned to nanotechnology to create enhanced robotic soldiers as a "defense against the threat of metahuman attack". This resulted in the creation of the
OMAC Project.[/FONT]
