Users are human beings born with abnormal genetic traits that allow them to bestow powers and abilities caused by evolution, genetic experiments, being bestowed powers from other beings or sources, etc.
Also, thanks to the human side of their heritage, (if the powers are genetic based) the user is able to use these abilities without becoming a monster, i.e. keeping their human physique, sanity, and humanity without it being altered from possible instability.
Depending on the amount of powers they possess by far, especially immunities, Metahumans can be much more stronger and powerful than regular Humans in the long run, for example, they could survive environments that would be otherwise dangerous to normal Humans, they can defeat threats that regular to peak Humans couldn't fight back, or even handle occupations to a much better intuitive standard, as well as better skills that normal to peak Humans could never hope to reach.
