Metahuman

The term "metahuman" -- or "meta" for short -- is a catch-all term used IC to refer to anyone with abilities beyond the reach of an ordinary Earth-born human being, regardless of where those abilities come from.

Thus, metahumans include genetic mutants born with innate superhuman abilities, people altered by mutagens or even by freak accidents to gain such abilities, cyborgs with techological implants, aliens (both extraterrestrial and extradimensional) with natural talents normal humans don't have, supernatural creatures, humans with magical abilities, etc.

In lay usage it has also been extended to apply to apparently "normal" humans who nevertheless demonstrate exceptional abilities based on training or technology or artifacts. For example, someone wearing technologically sophisticated power armor, or wielding magical artifacts, or even just someone who has developed ordinary physical or mental skills to an exceptional degree, may be referred to as a metahuman. (Technically speaking this is incorrect, but only an expert would care.)

The term "superhuman" is often used synonymously.

The terms "superhero" and "cape" are often used to describe metahumans who appear in public to fight crime or otherwise do good things. The term "supervillain" is often used to describe metahumans who commit crimes or otherwise do bad things.
