"This should do it." It looked down at itself, pleased.
The two - rather long - legs jut out under it's torso. It used it's new - ew - five fingers to feel along it's skin, feeling the bumps of a ribcage underneath. A heartbeat too.
In front of it was a mirror, and staring back at itself was a human. Well, an illusion of one.
Time and time again, the newly star bound aliens, humans, had infiltrated it's species ranks through elaborate disguises. They got better at it every time.
Not only were humans great with what they call "make up" but they had a way of mimicking their behaviors. It's species tried to replicate this. Failed to. In the end, they had something better.
A team of highly immoral scientists who were given boundless permission to try whatever the hell they wanted. And they went with genetic mutation.
It was a painful change, and slow. Agonizingly slow. But now, it was a super solider with one superpower. A shape-shifter.
And it was time to test it out.
It strolled out of the bathroom and into the eating area where various alien species were seated. Only one human - the unwitting test subject - was present.
If this could pass for normal conversation, this could pass for war.
It strolled right up to the other creature - a man who had not yet seen him - and sat down.
"I'm glad to see one other human on this station," it said.
The human non-committedly looked up. Only to jump with a start after taking it in.
"What are you?" he said.
"A human?" it said. If it's species could sweat, it would do so by now.
The man stared at it a moment. He turned to the alien on his right and pointed to his left.
"Forgive me if this question is batshit insane, but what do you see?"
"Two humans?" The alien had three eyes.
Her species' third eye was famous for detecting the most miniscule details and then committing it to subconscious memory. The rise and fall of a chest. The careful rythem of a human heart. How often - or little - a human blinks. Even human's make-up tricks couldn't bypass her species' extra form of security.
"So it is," said the man. She turned away and it found itself blinking quickly in relief. It cut that out when the human turned to it. "Sorry, I guess you're just real ugly."
"Ugh, rude." All humans are ugly.
He scooted in closer on the bench and leaned in towards it. It found itself leaning away, but couldn't help but notice the bead of sweat on the human's forehead and how the pupils were shrunken as far as they could.
"Wanna hear an old Earth tale?"
"I'm sure I know it." Was this a test?
"I doubt you know this one. My grandfather experienced it himself." He leaned away. It had stop itself from blinking too rapidly again. "This is about an Earth cryptid."
"Bigfoot?" it said, but nodded as if it already knew.
"Everyone knows Bigfoot," he laughed. "No, he was driving down a dark country road unlit by street lights. He didn't have his brights on - that's important to the story, you see - but heaven knows why."
Brights??? What are brights???
"Down the road an animal was crossing. A simple male deer with antlers. He couldn't see its body yet, but he was familiar with the eyes. They glowed as his car sped closer."
"He slowed as the deer became more apparent, and eventually came to a stop when the creature wouldn't move. By now, he could see the antlers, the four legs, the neck. Not in detail, mind you, but he could see it "
Other aliens in the room- not hearing this conversation - were trickling out of the room. There was no dramatic reason for this, they simply finished their lunch. The human, not paying any attention to his own lunch, continued the story.
"It's not uncommon for deer to freeze, especially when lights flood their eyes. So my grandfather gave it a moment to realize it should run. When seconds ticked by, he honked at it."
"There was something... off... about the deer. It looked every way like a deer, but the longer he stared, the longer that just didn't seem right."
"Was it a deer?" it said.
"It was not."
"What was it?"
"Not a deer."
The alien found itself frown at this in a perfectly human way.
"Time went on, and my grandfather decided to turn on the brights to try and see the creature better. And it was still... a deer... but not..."
It found its frown deepening.
"What's worse was it began to move. Similar to a deer, but all wrong. Like maybe its legs bent the wrong way. Or perhaps the legs were too long. It was every way like a deer, but it just was not."
"He drove home as soon as that not deer was out of his path. And yes, he found himself alive the next morning. But that encounter disturbed him, so he recounted it to everyone. And many people - especially in that town - could tell him their own stories."
"...okay?"
"Well, that story is funny. Probably a figment of his imagination, but it does reflect a very real human instinct."
This was another test. "Would this be something I know of?"
"It's called uncanny valley. It occurs to us when something looks human... but is not."
"Why?"
"Well, rumor has it that it was a instinct formed from a predator. Something that looked human but was not. A not human."
"A not human? Is this true?"
"No," he said. He laughed. "No, we most likely developed it for something a lot more practical. Corpses, you see. They carry a lot of bacteria, so we have a fear of them."
"...interesting."
"I have that very same feeling of you," he said. The room was empty besides the two. He reached for his bottle above his lunch tray.
"But I'm not a corpse?"
"You're about to be."
The human tossed down the bottle, effectively cracking off the bottom half and forming his weapon.
It shape-shifted as it scurried away to retreat from the very much human.
