See here for a list of people who have hosted various Symbiotes. Regardless of morality, they feed on their hosts' emotions, organic chemicals like adrenaline and phenethylamine (or just vital fluids in general), and flesh.

While the other symbiotes, known as the Symbiote Imperium or the Hive, would form their own empire and continue being parasitic, giving the species as a whole a bad reputation throughout the universe. The symbiotes that chose to rebel and attain true symbiotic bonds with their hosts would rebrand themselves as the Klyntar (their word for cage) and serve as protectors of the cosmos. Originally created to serve as parasitic and corruptive agents of Knull, Thor would sever their bond to their master and humanity would introduce them to positive concepts like love and honor, allowing them to rebel against Knull and develop on their own. The Symbiotes, also known as the Synoptic or the Symbian, are an alien species that usually exist in an amorphous state unless bonded to a host. Clockwise from the top: Venom, Scream, Carnage, Sleeper, Phage, Agony, Toxin, Lasher
