Teleportation in fiction is often depicted in various ways. Sometimes it's a flash of light and a person disappears from one place and instantly appears in another. For example, in 'Star Trek', they use the transporter which breaks down a person's molecules and reassembles them at the destination. In some superhero stories, like 'Nightcrawler' in X - Men, it's a more magical - looking blue smoke and a quick jump through dimensions to get to a new location.
Teleportation in fiction is frequently presented as a convenient plot device. It can be used to quickly move characters across great distances, whether it's across a city or across galaxies. In some science - fiction novels, teleportation is a carefully calculated scientific process that requires a lot of energy and precise coordinates. However, in more fantasy - based stories, it can be a more mysterious and less - defined ability that just works without much explanation.
