* At first appears to be the case in ''Webcomic/MareInternum'', when [[spoiler: some kind of Martian fungus attaches itself to Mike.]] Later [[JustifiedTrope justified]] when we find out that [[spoiler: Earth life evolved from Martian waste.]]

* ''Literature/{{Animorphs}}'' uses that trope a lot, with varying plausibility :
** Andalites are a species which [[FridgeLogic somehow]] eat grass with they hooves. Whether grass is something unique to both the Andalite planet and Earth or just a common biological formation for most inhabited planets is not developed.

** [[{{Animorphism}} The technology that game the series it's name]] is based on absorbing DNA. It [[FridgeBrilliance starts to make sense]] with ''[[{{Prequel}} The Elimist Chronicles]]'', which explain that the Ellimist [[spoiler:created the Pemalites to seed life on as much planets as possible, to beat [[EvilGod Crayak]] at their "Will all life in the universe be utterly destroyed or not" game]], so they probably used the same DNA-based cell for each one.

** The Star Trek novel ''Uhura's Song'' was all ''about'' finding the cure for an epidemic striking both humans and the catlike Eeiauoans, complicated (among other factors) by the fact that nobody on the planet that should hold the solution recognized its symptoms.

* Quofum, a mysterious world near the ''Literature/HumaanxCommonwealth'', has an '''insanely''' diverse ecosystem, featuring organisms with radically different biochemistry - carbon-based, silicon-based, sulfate-based, gaseous, etc - living side by side. By rights, most of these lifeforms and/or their waste products really ought to be poisoning one another, and the atmosphere shouldn't even be ''stable'', let alone breathable to humans. Yet neither humans nor thranx have any trouble breathing there, and the only signs of an unusual chemical environment are a pink sky and oceans that are 9% ''alcohol''. [[spoiler: Granted, the whole planet is a Xunca experiment, so habitable conditions may be maintained artificially no matter '''how''' incompatible its life forms.]]

* The Flood from ''Franchise/{{Halo}}'' can infest any creature with enough biomass and individual sapience to support the parasite. This specifically excludes Hunters and Drones (being TheWormThatWalks and a giant termite, respectively).

Added DiffLines:

* The Zerg Hyperevolutionary Virus from ''Franchise/StarCraft'' is able to infect any alien it comes in contact with. It's also usually paired with a neural parasite. This is Justified by having the virus, as per namesake, evolve rapidly (about a million times more in a week than humans ever have in two million years). And the assumption that everything has DNA to infect. However, it doesn't work on Protoss due to their PsychicPowers supercharging their immune systems.

* ''VideoGame/{{Pikmin3}}'': The Koppaites can eat fruit found on PNF-404 without any trouble. However, it is noted that they searched practically the entire galaxy for planets with food safe for them to eat, and PNF-404 is the ''only one'' they found.

* ''VideoGame/{{Pikmin3}}'': The ''VideoGame/{{Pikmin}}'': In the second game, Olimar discusses the possibility of bringing back the giant fruits and vegetables he finds for use as food on Hocotate, but he also notes that he's not a biologist, so he's unable to test for health effects. Louie also eats most of the native fauna (including one explicitly described as "inedible"). In the third game, the Koppaites can eat fruit found on PNF-404 without any trouble. However, it is noted that they searched practically the entire galaxy for planets with food safe for them to eat, and PNF-404 is the ''only one'' they found.
