Freddy's hotel: the purple suit

Mr. David's storage building counted as abandoned and Amy decided to buy it. She found some purple clothing and lots of blueprints of rejected animatronics and hotels, and she even found an animatronic creation center filled with automatic machines with scrap metal, parts, cords and chips. She was fascinated by it and she transformed the place into a museum in memory of Mr. David's genius mind.
But she was only doing it for the money as she was about to be broke. She spent her last currency on this museum and it was all worth it in the end as it gave her way more than what she paid for it.
Technicians, night and day guards and janitors were happy to help out for free or to get paid. One of the technicians decided to build the canceled animatronics so that the kids can be entertained and be played with.
All animatronics were made out of plastic. Water pumping and electricity from their endoskeleton kept them active. A computer was inserted in the center of them.
No accidents or abnormalities took place, that is until someone decided to wear one of the purple suits of Mr. David. It was a technician called Link Ludovic. He repaired many technical issues with the animatronics and was a big help for the team.
He had the key to enter every office and room, and as he was about to finish the job he saw an old rusted door with a broken knob. He was curious and wanted to know what stood behind this door, so he lockpicked it and turned on his flashlight.
At the corner of a wall he found a human-like endoskeleton with human teeth and realistic human eyes and nose. It also had its own thoracic cage. It was turned off.
He was flipped out by this humanoid endoskeleton and he tried to leave, but the door slammed shut behind him. He tried to open it but the door knob fell off, and as he looked back the endoskeleton was standing on the left instead of sitting to the right.
Everytime he looked back the endoskeleton would be closer, so he kicked down the door and began to run to the nearest exit. He made it out of the hellish place and he never looked back.
His car was damaged and pieces were missing including a few wheels. Link knew that it was that cursed human-like endoskeleton. Loud metal-like footsteps followed him and he heard a broken, low, robotic voice asking him,
Why did you abandon me, creator? I was meant to be the peak of technology!
Link yelled, swore at the robot and repeated that he was not its creator, but the robot didn't believe him and chased him in a forest faster and faster.
Link tripped face first on the ground and screamed, but no one could hear him as he was lost somewhere in a vast forest at night. Everything was deathly still and silent; not even animals made noise, it's just the wind.
The endoskeleton covered his mouth and got ready to take what's left of Link.
Endoskeleton
Finally with your body on my side, I will take over your kind as it was always meant to be.
The endoskeleton cut through the back of Link and wore his body as a suit. Now he looked like a living human. No clues were left behind. The endoskeleton learned a lot about Link's family and adapted to live like him and create more versions of himself to conquer humanity.
