There is some sort of carnivorous mega-creature. What it is doesn't matter. What does matter is that it can kill pretty much anything. Imagine a mini-kaiju. Like, only the size of a double-decker bus or two. If it wanted, it could take on an elephant, if any were nearby. Also, its skin is about as bullet-resistant as that of a tank.

Humans aren't aware of it.

Then, one night, a few hundred or maybe more of these pop up all around the world, crawl out of the sea, kill and eat something, and crawl back. Reasons for doing this are unknown.

My question is, what is the most likely first target of these mini-kaiju? Cows? Humans? Sea-birds by the dozen?

Likeliness should be from the point of view of statistics, about what creatures are most likely to be around in these places.

Of course there are going at least a few casualties from a whole bunch of species, but what species is going to be hit the hardest?

An additional thing of note is that it is not a turtle-roosting or hatching da or anything like that.

    $\begingroup$ Are the attacks targeted (ie part of a co-ordinated assault on humans or land in general, either among the kaiju themselves, or by a controlling force)? Or are they acting in an animalistic fashion, following some (xeno)biological imperative? $\endgroup$

    $\begingroup$ It depends what they are partial to real doesn't it? They may gorge on whatever creature they come across first or they might be a bit choosier, how can we tell? $\endgroup$

  • $\begingroup$ More to their point, what is their motivation for attacking? If it's food, there has to be a reason for why they don't just go for fish. $\endgroup$ Jan 24, 2020 at 13:21
  • $\begingroup$ If you get one answer for "cows" and another for "humans", how would you be able to determine which answer is better? This is completely open ended and on top of that it's not even a world-building question. "What happens in my story" is off-topic. $\endgroup$

  • $\begingroup$ @Stephen biological imperative. Maybe they are being crowded out from underwater, and are heading for shallower areas. $\endgroup$ Jan 24, 2020 at 13:39

Pretty much anything made out of meat.

Gathering from them acting from biological imperatives, a radical change of behavior in a species like this is very likely sheer desperation. Humans are the most prolific predators on Earth. We empty our seas of fish and these aquatic residents are fed up... or actually, not fed at all but still desperate to get their fill.

Evolutionary speaking, the creature hasn't left its terrestrial lifestyle long enough to eliminate its terrestrial abilities, even if it hasn't shown any interest in it before. Thus allowing it to walk on the surface. When hungry enough, people and animals will eat whatever they can sink their teeth in.

I want to make one little caveat here. If your creatures are biologically motivated, it tends to be a more gradual process. Isolated events at first when issues start manifesting which increase in frequency as an undesirable situation persists or worsens.


Does it want to eat? It could attack big mamals easy to find.

Is it in fear, pain, angry? It could attack any light and sound sources, that means cars, buildings, etc.
