A metahuman is a human being with superhuman abilities, whether they be physical, mental, or both. Metahumans are a common trope in science fiction, and they can be used to explore a variety of themes, such as the nature of humanity, the limits of human potential, and the dangers of power.
There are many different ways to create a metahuman in science fiction. Some common methods include genetic engineering, exposure to radiation or other hazardous substances, and mystical or supernatural events. The specific method used will often depend on the story’s setting and the desired tone. For example, a story set in a near-future world might use genetic engineering to create metahumans, while a story set in a fantasy world might use mystical or supernatural events.
