      Technically technically, … I can’t think of a specific example involving humans… but a Slaaneshi cult would absolutely both fuck and/or kill other species if so inclined.

    My favourite alien invasion scenario is a small meteorite containing a small core of self replicating nanobots.

    It lands on the surface, cools down to a moderate temperature and then starts replicating using the surrounding material and minerals. First day, there’s nothing, second day still nothing, a week later it looks like mold, a week later mold is now a meter square, a week later it is a kilometer square, now it looks like a moving liquid and just starts spreading around and even lifts into the air in wisps and starts spreading in new areas everywhere down wind. A month later, it’s liquefying whole fields and the spread is jumping into the oceans, jungles, deserts, even mountains, ice caps and glaciers. Six months later it is on every continent and people are becoming infected with the air borne spores … it makes them sick, unwell and eventually kills them as the nanobots consume their organs and body parts. Pictures come out everywhere of forests being consumed, animals, birds, fish, everything and anything. Militaries and scientists try to figure out how to destroy it … fire, chemicals, radiation, extreme heat, extreme cold … nothing works. Extreme heat seems to work but only at the rate of tens of thousands of degrees at a time, same with extreme cold to near absolute zero conditions which only seems to slow it down. Neither extreme heat nor extreme cold mechanisms can be employed without massive amounts of energy.

    Within a year, its everywhere and only accelerating exponentially without end.

    A year later, the entire planet has been liquified into a long never ending global mass of nanobots floating on a sea of magma on the earth’s surface. No mountains, no oceans, no land, no water, no atmosphere, just a never ending sea of grey formless matter.

    … and a thought that often reminds me of how dangerous the universe can be is the idea that there might be random small or large meteorites like the one I described here, may or may be floating around randomly through space waiting to just land on a planet like ours.

      Similar to this are uh… tiberium, some kind of alien fungal infection or virus or bacteria that integrates with the biosphere in a parasitic/mutualistic way… and ice-nine.

      You could also maybe have… what if a giant mass of whatever Odo from DS9 is actually made of… somehow crashes on Earth, or any planet… and then over the course of centuries or millenia… the meta material eventually segregates, escapes its pool… and slowly but surely acts as basically a plague of mimics, just getting better and better at assuming the forms of all biology on the planet, potentially massively disrupting the ecosystem before they become conscious and cognizant and sapient enough to realize what they’re doing.
