* The movie ''[[Venom (2018 film)|Venom]]'' explains that this relationship becomes mutually necessary for a symbiote and their host: the symbiote needs to eat {{spoiler|living creatures to survive, and would prefer brains}}. Meanwhile the host cannot heal from the parasitic infection unless the symbiote heals them, using energy from {{spoiler|their food}}. In the sequel ''Venom: Let There Be Carnage'', Eddie and Venom have made compromises: {{spoiler|Eddie has Venom eat chickens instead, while keeping some for pets, because they can't eat every bad person in San Francisco; even one every couple of months is arousing suspicion from the cops. Meanwhile Venom heals Eddie's wounds, and at least tries to mend his broken heart when Anne announces she's engaged again by cooking him a hearty breakfast}}.

* In the ''[[Plague Year Series]]'' by Jeff Carlson, a deadly nanotech has covered the planet and exists everywhere below 10,000 ft feet in elevation.

Unfortunately, the original nano will never go away, so it and the vaccine nano are now permanent facts of life.
