I feel like any aliens that were prey at some point in evolution would have an odd fear of humans. Mostly cause they look like predators, act a bit like predators, and ARE predators. One perfect example is when we're focused on something like a mosquito that's been bugging us for a long time and we are just done.
Alien: "What. What..?"
Human: *HUNTING down a mosquito it saw*
Alien: ".... yeah I am really uncomfortable...."
Human: *quiet footsteps, pupils dialated, intense focus,*
Alien: *WAR FLASHBACKS*
Human: "Found you." *absolutely desimates the mosquito, squashing it into a million pieces as it's guts and various body parts liquidize into blood of the bloodthirsty, now stained on the palm of the human. A living being now reduced to a useless corpse as the human wipes the remains on their pants*
Alien: "I feel like I've just gained trauma."
okay fucking fun addition to this post. Hunting instincts in humans absolutely still exist and are usually triggered either by fascination or anger. The polar opposite of flight is pursue. An anecdote for this is that the other day my sister, who is an avid "take the bug outside in a cup" rescues kittens in her free time kinda person, looked out the window and saw a chicken in the middle of our driveway. which is a very unusual occurrence despite us living in the country.
All she had to do was say the words "there's a chicken" and her as well as my own body language immediately shifted. We were out the door and in the yard already sorta hunched over and walking on the balls of our feet, fucking flanking this chicken. No words were exchanged. We just slowly circled this chicken like a couple of rabid dogs. totally single-mindedly focused on capturing the prey.
The chicken could feel it, it immediately began counter maneuvers to avoid us and it was faster. But there were two of us and we knew the land better, we knew how to herd it into a corner, carefully watching it's body language and lurching to counter it's escape attempts. And it was fucking thrilling.
Of course, when we both closed in on it and finally got our hands on the poor thing we simply took it into the back patio away from the cats and the vultures that wanted to actually finish the job. No harm came to the bird. We located its owner and returned him to his flock but still. From an outside perspective, it was a bit unnerving. And for the chicken, it was no different than being hunted. He was just lucky enough that we were predators who appreciated the companionship of pets and were more concerned with returning him to his humans than eating him.
Now imagine any fucking alien species watching a pair of humans, who literally rehabilitate animals in their free time, who are not soldiers and seem to be totally domesticated, just absolutely flip a switch and turn into pack-hunting pursuit predators? On a single word.
(felt like the bulldog from Rio's bird chasing monologue hit a little too hard after this)
