If you've watched Godzilla and Pacific Rim you know what a Kaijuu is.
Kaijuus are monsters of epic proportions, as tall as the Empire State building or as large as 3 supercarriers of the USA.
I'm currently writing a short story about why monsters from "Another Dimension" keep attacking Earth.
Currently I have these reasons:
- Prevention - Some super advanced alien species deemed humans way too destructive and periodically sends their monsters to cull the human population.
- A viable world to live in - Kaijuus are living organisms as well, they have deemed Earth as a good place to stay and see humans as pests.
- Conflict - Some hub dub story of a god siring 2 species, one of them are the Kaijuus who inherited the power, and the other are the humans who inherited the wisdom of the said god. Ever since, they are at war.
- Emotional Negativity - They are attracted to the emotions of humans, particularly negative emotions.
As you can see it's rather short and I think the above reasons are rather superficial or not sufficient enough for Kaijuus to try annihilate the human race.
Are there any other probable reasons why a Kaijuu would attack humans?
Or are the reasons above sufficient enough to explain why Kaijuus are killing humans?
