Deviants are superhumans who possess abnormal abilities afforded to them by the "muta-gene". They are humans with powers that were not granted to them through means of magical or cosmic forces, but instead were born with such abilities.
Deviants can be present in both humans and animals, and their abilities can range from manipulation of a certain forms of energy or matter, to flight, enhanced senses and strength, or other physical and mental enhancements. Basically, they can possess a wide array of powerful abilities that puts them on par with and even surpass other supernatural creatures
Deviants, despite their human origins, have many distinctive traits in regards to biology, physiology, and genetics from their evolutionary predecessors. Deviants can have wildly varying biological appearances depending on the nature of their mutation. Deviants can also come in categories and that is evident in an Omega Deviant. An Omega Deviant is one with the most powerful genetic potential of their mutant abilities. Some abilities depicted by deviants described as Omega-level include immortality, extreme manipulation of matter and energy, high psionic ability, strong telekinesis, and the potential to exist beyond the boundaries of the known physical universe.
Mutation, in question, is caused by the "muta-gene" in the Deviants' DNA. Mutations normally manifest themselves during puberty, often as a result of a traumatic event. Some Deviants exhibit their mutations at birth, however, while others do not manifest their powers until adulthood. Deviants can also develop a secondary mutation, whereby their mutant physiology is capable of responding to the need for survival. Thus in rare occasions a deviant's powers change or become even greater, and in rare cases they can develop a new, often unrelated ability.
Normal humans, either out of fear, jealousy, or prejudice often detest and reject Deviants, calling them "freaks", "mutates", or "abominations" and, on many accounts, physically abusing them or those suspected to be one. This in turn caused many Deviants to live out in the streets, be on the run from authorities, learning how to survive on their own, and even willing to kill others either for their own gain or other personal reasons. Many Deviants have stated that their own families shunned them for their abilities, which has lead to verabl and even physical abuse to where they even have been kicked out of their own homes.
While Deviants are seen as 'monsters' by many, they are nonetheless capable of showing emotion and acting like any other human due to them being born from human mothers in the first place.
