Superhuman qualities are qualities that exceed those found in humans. Superhuman abilities are found in some fictional characters, especially as superheroes in American comic books. Fictional characters have been portrayed as having psychic abilities, flying abilities, impossible strength, or exceptional proficiency beyond human capability. Superhuman can also mean something that is not human, but considered to be "superior" to humans in some way, e.g. a tiger may be described as having "superhuman strength".
Superhuman abilities may result from human enhancement by genetic modification, cybernetic implants, nanotechnology, radiation or from human evolution in the distant future.
