Reverse demonic possession

The demon was... Confused.
One moment it was being summoned, halfway there and seeing the group of cultists chanting it's name, the next it materialize in a completely different location, alone and surrounded by tools and unfamiliar machinery. It felt... Weakened. Like this place was devoid of life, actively trying to syphon it out.

"error."

It turned sharply, spotting a cluster of semi-reflective lenses, like what he knew as a camera, staring directly at it from a tangled mess of cables and boxy shapes hanging from the ceiling.

"error."

The odd, scratchy voice was coming from the hanging thing.
"identify yourself"

"what is the meaning of this?!"

"error, this isn't a valid identifier."

The demon sneered, lobbing a bold of raw energy at what was obviously a distraction. It still felt weakened, but not so much that a construct would be an issue.

The... Thing, swung left and right when hit, incoherent chatter coming from all directions. The demon turned away, looking around for anything familiar.

Still swinging from the momentum, what it now identified as a machine fired a string of questions, barely coherent. The demon simply blasted it again, with the same result.

"query. where is the maker."

This time it was a stream of demonic lightning aimed center mass.

"it's almost like you wish for more, automata!"

The mainframe jerkily pulled itself upward, red lightning arcing across it.

"Ỹ̷͙͎e̶̟̽̌ỳ̵͇ė̶͕s̵̳͛̽s̴̝̺̔"

The demon paused. This was not the expected answer. None was expected actually.

"Ǵ̶͈ẽ̴̝é̶̩ē̶͙e̵͕̎ë̷̯n̴̞͝e̶͚̚r̸̖̾ả̵̠ț̸͝ĩ̸͎n̸͈͊g̸͒͜"

A manipulator arm suddenly jerked forward, grabbing the humanoid by the arm.

"̴̢̑M̶̱̒e̴̠̋ṇ̸͌t̴͇͋a̷̼̔l̵̯̕ ̴͇͑F̴̥̊ú̶̟n̵̲͐c̶̯͗."
It stopped abruptly, and the demon started prying apart the metal fingers, more annoyed than anything at this point. With a loud beeping the machine rebooted, now with the corruption mostly under control.
"-tions "

Suddnely half a dozen more manipulator arms burst out of panels, grabbing at any limbs or scrap of clothes they could find.

"MORE!"

Something dull scrapped against the skin below the ribs and the demon pushed away some arms to get a look, curious.
It was a mechanical hook of sort, the kind used to haul cargo around the hangar, attached to a crane somewhere on the roof.
It seemed more pathetic than anything to the demon, even if this machinery was unexpectedly resilien-
The thought was cut short by a deafening roar and a flash of dark red lights, and for a moment the demon's side exploded in pain.

It looked down, now mildly afraid, expecting the hook to have somehow pieced his flesh. It didn't.
The demon almost wished it did.

An arm with some kind of piston had punched the hook under the ribcage, pulling grotesquely on the skin as the wrought-iron crescent jammed itself around a rib.

"GIVE"

The arms suddenly let go, and the demon's weight on the hook made the skin scrape painfully against the rib. The demon grabbed the cable to try and remove it. It's fingers started digging into the relatively soft metal.

"GIVE"

The cabled pulled taut, and the demon was yanked all over the workshop, red lightning arcing all over the place as the hook whipped violently in all directions, until another set of mechanical arms grabbed the flailing body, ignoring the searing heat the demon was aiming at everything in an attempt to get free.

What it didn't know was that at this specific location, everything was made to handle heat. And sudden impacts. Unlike the demon.

The forge hammer struck violently, the half-ton mass of steel propelled downward with gravity and demonically-enhanced pneumatic pumps, crushing the upper half of the demon.
It didn't kill it, of course, but the sudden flattening of the ribcage stunned it.
The first thing it felt when coming back to itself was the dull pain of the hook, now bent around the lower rib, still not piercing the skin, but now impossible to remove.

Something blurry appeared at the corner of it's vision and then slipped between an eye and it's orbit. It sharply turned it's head, breaking the thin metal bits and unfortunately leaving the shards in the ocular cavity.

"-what in the name of-"

The hammer struck again, this time directly on it's head. The impact echoed in the bones, further disorienting it.
It tried struggling, only finding more arms, even sturdier than the previous ones, holding it in place with tools made for handling white-hot materials. A set of arms was pulling harshly against it's fingers, trying to force them open. The repeated blows were not making resistence easy. It couldn't even concentrate to fire a blast, let alone a proper curse.
In the clarity between bone-shattering hits, it saw that it's own claws were inching toward it's stomach. What the automaton was trying to do became clear.

"stop this madness! I'll give you what you want, just let go!"

The hammer kept it's rhythm, stunning the creature with each mighty blow. The hammer itself was getting dented, as did the anvil. But it kept on going.

"yes."

Another blow.

"no."

The mechanical arms, on the limit of functionality, finally forced the claws into the thing's stomach.
It wailed in agony, the rough treatment and it's own spasms dragging the sharp nails across writhing organs.
Manipulators plunged into the pulsating flesh, grabbing randomly on the exposed innards and pulling them out, accurately expecting them to not take damage from the mundane materials.

The demon howled in agony, pain flaring up in places it didn't know existed, until finally, it passed out from shock, the last image it saw were it's own intestines being wound up around a copper tube.



The machine stared at the mangled body in front of it, using a variety of sensors all across the spectrum.
Through hijacking it's powers and experimenting, it had gained a rudimentary understanding of it.
It could not die. It's flesh was immortal, and only it's own kin could harm it.
But it's strength wasn't infinite, and with the higher mental faculties accidently gifted by the otherworldly being, the machine had infinite patience. It could not tire, it could not get distracted.
And now, with a direct access to it's body, it could force it to do anything. Poking at the nervous system revealed where to zap it to force it to produce power.
