The Klyntar, colloquially and more commonly referred to as symbiotes, are a fictional species of extraterrestrial parasitic life forms appearing in American comic books published by Marvel Comics, most commonly in association with Spider-Man. The symbiotes, as their alternative name suggest, form a symbiotic bond with their hosts, through which a single entity is created. They are able to alter their hosts' personalities and/or memories by influencing their darkest desires, along with amplifying their physical and emotional traits and personality and thereby granting them super-human abilities. The symbiotes are also weakened when in range of extreme sounds or sonic frequencies. There are more than 40 known symbiotes in the Marvel Universe.
