The Symbiotes (originally known as the Klyntar) are a fictional race of amorphous extraterrestrial symbiotes appearing in American comic books published by Marvel Comics. The Symbiotes bond with their hosts, creating a symbiotic bond through which creates a single entity.

The first appearance(s) of a symbiote occurs in The Amazing Spider-Man #252, The Spectacular Spider-Man #90, and Marvel Team-Up #141 (released concurrently in May 1984), in which Spider-Man brings one home to Earth after the Secret Wars (Secret Wars #8, which was released months later, details his first encounter with it). The concept was created by a Marvel Comics reader, with the publisher purchasing the idea for $220. The original design was then modified by Mike Zeck, becoming the Venom symbiote. The concept would be explored and used throughout multiple storylines, spin-off comics, and derivative projects.

The Klyntar, as the symbiotes call themselves, originate from a planet of the same name in the Andromeda Galaxy, and are a benevolent species which believes in helping others, which they attempt to do by creating heroes through the process of bonding to the morally and physically ideal. Hosts afflicted with chemical imbalances or cultural malignancy can corrupt symbiotes, turning them into destructive parasites which combat their altruistic brethren by spreading lies and disinformation about their own kind, in order to make other races fear and hate the species as a whole.

The corrupted Klyntar became more widespread than their benevolent counterparts, establishing a space faring culture dedicated to infecting and overtaking planets. The corrupted Klyntar force their hosts to perform death-defying feats in order to feed off of the resulting rushes of adrenaline, and other hormones, such as phenethylamine. These host beings would be sucked dry, exhausted by the constant stress and exertion, or simply die in a failed stunt.
