THE FUTURE, 2125
Michelle was your typical teenage girl, a little older than 18. She was a red-haired, 6'0, 170 pound average girl, neither prep nor a freak. She was openly lesbian and liked to flaunt it a bit. She lived in an isolated home 10 miles from the nearest suburb; her parents were away on a week-long vacation. She'd be left in charge of the house until they got back. She didn't mind terribly, as most of her friends didn't live too far away and she could take care of herself. Right now she was idly walking down the street, thinking about the future. Forests were all around her, though she knew one day they'd all be torn down. The evening was normal. And then she heard the faint, strange noises coming from the forest. They were sounds she had never heard before, and curiosity got the better of her. So she walked into the woods for a while, the sounds growing louder and louder. Finally she came across an injured woman; or rather what she thought was an injured woman. It was only when she got close that she saw that the woman wasn't human, not looking the way she did. No human has eyes that glow whitish-blue in the dark. Michelle froze, unsure what to do. She had never met an alien before, and that was definitely what was in front of her.
"Miss....I require assistance. My ship has crashed and I...am stranded here." the femme fatale voice sounded faintly synthesized.
The woman-thing got up from her prone position, and faced Michelle.
"Would you feel more comfortable if you could see me?" said the odd voice.
Michelle could barely get her lips to move, "Who are you? What are you?"
The humanoid activated a series of illumination lights, apparently set on low, as they provided enough light to get a good look at her and nothing else. Her body was strange-looking, seemingly machine-like but not made of any metal she had ever seen before. Her skin (or whatever it was supposed to be) was primarily white with black trim in many places, and strange brilliantly colored ornamentation in others. Her hands, face, and neck were light grey; her eyes were an intense shade of whitish-blue; and her punk-cut hair was white. The body of the strange humanoid was generating extremely faint but audible sounds: humming, beeping, pulsing, clicking, and several other strange sounds.
"My name is the name I chose for myself: Karen. My species is classified; my origins are classified; my mission is of the utmost importance. But that can wait."
Michelle stammered, "Are you...hostile? Are you here to take over our planet?"
The machine-thing called Karen laughed out loud and shook her head, "Even if I was hostile, there are hardly any of us left."
As soon as those words left Karen's mouth, she frowned in visible discomfort: "I should not have said that. I cannot believe I said that. No longer we got slaughtered....can't keep our damn mouths shut."
Michelle whispered, "What are you?"
Karen smirked, "I am a biomechanical life form from....obviously what you call outer space. My body is like a mechanical one only with biological components that essentially duplicate the functions of both an android and a biological humanoid. I have multiple power sources, even an emergency digestive system of sorts if it ever becomes necessary. It isn't like yours, my stomach is located in my back and food is ingested from the side. What are looking at me like that for? I'm a bloody alien...of course my organs are going to be different from yours! I have both a biological and technological nervous system that work in synch with one another...hence my ability to do calculations and have emotions. I am incapable of conception, although I have female sex organs my species are born sterile. My species does have a connection to this world, but I won't tell you any more than that. Not yet anyway."
Michelle was confused, "Why are the flesh-and-blood stuff?"
Karen signed, "Part of an experiment. I have the dubious distinction of being the prototype of my species. There would have been more of us if some group of unknown (a lie) aliens hadn't attacked our homeworld....I have no idea if any of the others survived. I think our attackers were anti-technology biologicals...probably the same species as whoever designed us. I bet our reproductive cycle was just too alien for them...they probably viewed us as abominations."
Michelle had been shaking her head for some time now, "Ok. Ok. That's great and all but why are you here?"
Karen smiled faintly, "I'll tell you later. I don't know if this is an unreasonable request or not, but can you please hide my in whatever sort of home you have? I don't think the locals will take kindly to my being here?"
For the longest time Michelle paused. "She doesn't seem dangerous...." thought Michelle.
Michelle signed, "All....right. Just don't do anything stupid like turn into some ugly bug monster or some shit like that. You can mimic humans right? You do have an ability to change your appearance right"
Karen tilted her head; "I can indeed make myself look human at will, as I already resemble the majority of the human body in shape anyway. (signs) I hope the rest of my species is having better luck with whoever the hell they've run into."
Michelle stuck her tongue out at the biomechanical thing called Karen, "Come on this way."
Then something troubled her, "Wait a second. If your stomach is in your back....away from where our digestive system is....well you do have...well you know?"
Karen nodded, "Yes, I do have a storage organ where your stomach would be, and a tube that connects my pseudo-stomach to my mouth."
Michelle looked puzzled, "But why? If the false-stomach and esophagus aren't for eating and digestion, then what the hell are those organs for?"
Karen smiled with a hint of mischief, "As I said before, miss, my organs aren't like yours. My digestive system isn't like yours."
And under her breath, so that the human couldn't hear, "And so is my artificial insemination system, which you definitely don't have. That's what my so-called digestive organs are really for. And, if you are willing to someday miss, you'll find out exactly how that impregnation system of mine works."
Michelle's Home
When Michelle agreed to hide Karen, she wasn't expected her to stay long. That brief stay turned into 3 months. During that stay, the federal government came looking for the missing aliens. Karen was understandably frightened, but Michelle figured the best way to hide the lost alien was to hide her in plain sight. For those 3 months, Michelle made up a story about Karen and kept her as a house guest. Her parents didn't really mind, they already assumed that Karen was her newest "girlfriend."
Karen was a fast learner, and did a reasonably convincing impersonation of a human teenager. In that time span, Michelle showed Karen around human civilization. It was difficult for Michelle to remember that Karen was an alien, as she was always in her human disguise for all that time. It definitely helped cool the tension between them, and a bond formed between them. It was only when her parents left for another trip, this time on business, that Karen told Michelle the real reason she had came to Earth.
