Bendy and co.'s bios located on my DeviantArt.

60 years ago…

A heartbeat rang through the halls of the broken studio, growing faint with each pulse as the room seemed to grow smaller with tainted breaths.

Henry busted down the exit. Bits and pieces of wood flew in all directions as did some of his blood. Coughing, he peered around him. It had been six days since he last saw the light of the sun. He should have been happy but no joy came to his features splattered with blood and ink. He clasped the grass with tears burning down his black-stained cheeks, giving a soft moan as he stayed still.

"Bendy", "Alice" and all those monsters that once were his peers finally have been destroyed. Boris sacrificed himself to protect him, the only Toon he actually wanted to save. The Ink Machine, however, he could not touch although he managed to shut it down. A pentagram scarred its side rendering it unbreakable as he learned with some of those Bendy cutouts. Who put it up there was most likely none other than Joey who had escaped in their final confrontation with "Bendy". Joey had helped him kill the monster but left him behind to deal with the others as if he blamed him for everything going so wrong. Figures, his former best friend never liked taking the blame for his own mistakes.

Against his better judgement, Henry peered back into the opening of the building. Some of the walls had caved in leaving the Machine exposed to see. It was strange how the Machine acted before he stopped "Bendy"; he had accidentally placed his hand upon the pentagram the same time as Joey did and small surge leapt into both of them it seemed. He almost felt…younger, like all his energy from his teenage years had returned. He felt immortal.

Now that he thought about it, what will happen when somebody unintentionally stumbles upon the Machine? To reactivate it would prove fatal. It was a little miracle he was still alive but he recognized some of the ink monsters' mannerisms so he had gained an advantage. After all, he was their true maker. He pitched and designed them, animated them for the silver screen but everybody gave Joey the credit. It was sickly sweet how the cartoons knew who their real creator was.

Scoffing, Henry stood up and dragged the half-broken axe he had stolen from "Alice" prior with him away from the desecrated studio. It was all over now. The nightmare was no more. He was ready to leave it all behind.

He did not hear the heartbeat within the Ink Machine's former citadel. He did not hear it slow down nor did he hear it cease. The Machine's painted pentagram stared at him as he left it behind once again.

The Allspark's blueish white color turned blood red as alarms blazed through Sumdac Tower. Its rings' symbols followed suit, groaning angrily while a darkened form fled its chamber. In the corner of its room, a piece of crystal fell off broken spherical casing and faded to a dark blue as it shattered upon the ground.

Bumblebee raced to the Tower with Bulkhead and Arcee in tow. Nobody had ever breached the Allspark's chambers before so it was obvious he along with many others were in a panic. He could see the plant life surrounding the Tower wobble and twitch, feeling the Allspark's rage surge within them as the top of the building pulsed a demanding red light through its windows.

One window on the second floor suddenly busted open with glass flying in all directions. The dark figure did not hesitate to jump out of it, hitting the ground with a perfectly timed roll to prevent injury. He froze when the three Autobots and several police cruisers slid to a halt. Holding an axe, he twirled the weapon in his hand and struck the asphalt with malice as a warning.

"I don't know who you are or what you want but stealing something from the Allspark is going to cost you nearly thirty years jail time at least. That's an extremely hefty crime, dumbass," the Camaro scowled as he transformed into robot mode.

Raf exited him with a gun drawn but raised a brow, "All this guy brought was an axe? Are you joking?"

The thief supposedly narrowed his eyes but with a cartoon character mask no one recognized covering his face, it was hard to tell. A portal erupted behind the criminal. Smiling, he immediately rushed through. It closed before anybody could stop him.

"Wha-?" The human stared in shock.

Arcee and Bulkhead shot each other looks before the Wrecker spoke, "I really hope the Allspark can trace its component as well as it used to."

"I hope so too," Bumblebee growled.

Two weeks later…

Nothing had come up about the Allspark's missing fragment and for once, the Allspark itself could not see its own piece anywhere. It must have been somewhere underground or among heavy mineral deposits to shield its signature. It was hard to say if it had been used for evil but the Allspark had yet to complain.

Ratchet had attempted to trace the Ground Bridge used but its origins were scattered as if the signal had been disoriented as well. The thief apparently was a lot more cunning than Bumblebee had originally thought so he'd give the guy that. It wasn't until a sudden power spike hit their radar did everything change.

"The outskirts of Chicago just fluxed a huge amount of unknown energy. The readings indicate that this surge has actually been operational for the last week but only now has its strength grown to the point where it could be detected. If my instincts are correct, it may be the Allspark's fragment," the medic groaned.

Arcee frowned, "Tell Optimus that Bumblebee, Bulkhead, and I will check it out. This guy is in serious trouble!"

Nodding, Ratchet poked in the coordinates and the Ground Bridge activated aggressively. It didn't take long for the femme to gather her two friends and soon enough, they darted into the vortex. When they exited, they found themselves in the middle of an open field in the midst of a large abandoned building.

"'Joey Drew Studios'? The thing looks like it was designed in the late nineteenth century!" Bulkhead exclaimed.

"Yeah but that would make swell for a hideout."

"Actually, Arcee, I get the feeling that isn't it," Bumblebee said as he pointed behind the building where a mining tunnel among the mountain lied.

The Wrecker whistled, "Those beams look like they were recently installed almost like it was built not too long ago. In fact, they're so new they appear like they were put in within the last few weeks!"

The two-wheeler grimaced, "That's impossible!"

"There's only one way to find out. Autobots, be on your guard!" The muscle car growled.

As they passed the building, all three could make out a few holes within the side but what was inside made them a bit worried. Dark splatters, old and crusted, lined the walls. Broken pipes and rotted posters that had the same cartoon character face the masked man wore also littered it but one area had an unusual outline on the floor where several pipes were broken. Some sort of well or machine had been moved.

Bumblebee paused and leaned into the small hole in the building. He could make out the damaged lettering on the posters barely but one word he saw on all of them was "Bendy". Why someone would wear a mask based on a character no one knew, or at least none he could research, was beyond him. Even the internet did little to help him as his internal web had practically no results except for a few things regarding Joey Drew. All it said was he was an animator and the boss of the company that went bankrupt during the Great Depression. It failed to specify why this "Bendy" was of any importance. As one could guess, he was the main character with "Alice Angel" and "Boris the Wolf" being his friends…or comedic opponents. There were even side characters like "Casey the Cargo Train", "The Butcher Gang", and even "The Fiendish Flock", all of whom seemed like antagonists or neutrals.

Then he noticed the cutouts. Human-sized cutouts stared at him from the back of the damaged room. They looked just like the mask the thief wore but slightly larger and less decayed minus the usual wear and tear. One floor belong them, a small hole was present. It was pitch black; maybe it led to the basement? He dismissed it as he signaled for his peers to follow.

When they reached the entrance to the mine shaft, one obvious thing that stuck out was the fact that the entrance was larger than Bulkhead. It also marked the beginning of rail tracks but they weren't rusted or even scathed, they were shining like new. It was wide enough to fit a train, perhaps even a Ultra-Electric Bullet Train which was currently the largest engine in the world. Whatever the mysterious masked man stole the fragment for, it was clear it may have been for someone more so than personal gain.

The Autobots walked down the tunnel with their headlights on for a few minutes as it seemed to go on for a bit. The farther in they got, the more they began to see prints similar to the ones in the building lined upon the wall of the tunnel. This time, though, the pictures were much more refined. In fact, they had extremely little worn areas at all. They too seemed new.

The Dancing Demon, Hell Fire Fighter, Sent From Above, all of them were perhaps lost cartoons or pitches for supposed skits that never got around to being made. Whether they actually existed anymore was not known. A few more cutouts lined the rocky hall and they apparently had new companions, plushy toys of Bendy, Boris, and Alice on the ground beside them. Some had crooked painted smiles while others had eyes missing and stuffing prodding out of its housing.

"Primus, this is creepy. Did this guy have an obsession with these cartoons?" Bulkhead muttered.

"Perhaps but maybe since it seemed to have fallen in the hands of this Joey Drew guy, he kept all of it because his family had worked on these shorts as animators or supervisors prior. Who knows how-"

Arcee suddenly paused, "Shh! Do you hear that?"

Both mechs froze in place, listening for the sound. Bee's optics narrowed. Indistinctly, he could hear…machinery. Gears grinding against others, assembly belts moving, and even faint whistling that was in tune to a song he did not recognize. The whistling ceased so it was apparent there was someone inside.

Slowly, Bumblebee moved forward. The tunnel began to curve to the right before light became present at what was assumed to be the end. When their optics adjusted, all three gawked at what they saw. A very spacious area with wood intertwined with rock on the cavern walls while it made up the floor and several staircases both human and Transformer sized. There was a towering pillar with the words "Heavenly Toys" on a custom sign on one side of the vast place also supporting a black liquid waterfall and enlarged toys sitting on the railing to its pool. Posters and cutouts were in great abundance, scattered high and low. State of the art technology was also embedded in the walls mixed with much older items like box TV's that supported very little color. Some of it almost looked like it was stolen as he had only seen the technology in the military forces. All of it was newer than what was seen outside.

The ceiling was mostly rock except for a patch just lopsided to the dark waterfall and a hole in the center in which beams of sunlight poured through though vegetation blocked some of it so the light itself was not too overwhelming. Grass seemed to have outgrown the surface and now started to climb upside down from the cavities above to the ceiling. Vines from a willow also hung down but the floor under both the gaps were surprisingly not covered in wood like the rest of the area, most likely to prevent the wood from decomposing from the moisture.

On the upper level accessed by staircase, three entrances resided to other rooms most likely. Three huge facial cutouts of Bendy, Alice, and Boris were above each with Alice's having the slogan "She's Quite a Gal" attached below her head. Alice and Boris were facing one another but Bendy was across from the other side of the area which held another room surrounded by gears, a sealed off door and the same type of pipelines Joey's studio held. Briefly the pipes pulsed and the small surge simultaneously followed the tubes into said concealed room. If the fragment was here, there was a chance it was in that room.

"Strange," the Camaro whispered. He peered back at Bendy's hall when he noticed something very off-putting. Plastered in the corner between Bendy and Alice's rooms, a pentagram rested. He remembered it was a symbol of darkness, one of ill and chaos. Whoever put it there did not have good intentions. Then again its religion sometimes was demonized in a greater scope than it deserved so perhaps it was a warning for intruders to scare them off.

The roar of a train whistle suddenly echoed through the tunnel making all three bots turn towards where they had just come from fully alert. Light upon the rock walls grew brighter around the turn as Bumblebee signaled for his team to move towards the side of the tracks they stood on. A slight rumble followed before a blur of black and white zoomed past them. Instead of curving with the tracks, the large train flew of the course and dove downward to the ground with such velocity. But it did not crash. The vehicle unexpectedly phased through the ground with no resistance, a ghostly groaned emitted from its actions until it disappeared completely with only a puddle of the same black stuff making up the waterfall present. The puddle seemingly shrunk and vanished.

The Autobots stared in outright horror when their attention was drawn to a similar roar which made them witness the same train spawned from a vertical wall to their left surge upward with the same amount of speed into the ceiling. It left its temporary exit and entrance puddles there as well. When they were no more, once again the train appeared at the far corner of the wall adjacent to the bots but this time it crawled across the wooden floor with its wheels like a centipede before curling around a column of rock in a serpent-like fashion. When it finally sat still, Bee's optics widened.

Eight passenger cars the train had but what linked them together looked like one black mass skewered through them and yet the cars' interior was visible with seats. The last car's end was flattened like a platypus' tail but with roof-bound spikes lining it. Its engine car had a smoke stack and yet the train resembled more of a freighter's appearance than a steam engine, the former of which had no chimney. What stood out the most were the facial features, especially the eyes, similar to the cartoon characters present in the posters and merchandise but it wasn't a cartoon…it was real! The fact that it had a face in general molded upon its appearance was scary. Then a thought struck Bumblebee: Casey the Cargo Train was a cartoon. No, there was no way that could be because cartoons cannot come to life!

The train suddenly jerked its head towards the Autobots with a scowl before narrowing its eyes. Licking its lips, sharp teeth flashed as a predatory grin formed. Arcee began to back away, making it lock onto her with a hiss until a dark laugh emitted from it.

"Arcee, don't move! You're baiting it," Bulkhead swallowed.

The window shutters on its body clattered like a rattlesnake's tail. It reared the same way as a serpent would when preparing to lunge and Bumblebee swore that had to be the scariest thing he had ever saw. Jaws opening with internal mandibles outstretched, the train roared and leapt towards them. Bulkhead tried to cover both of his friends upon instinct until…

"Casey!"

The train used its wheels to slow itself quickly and clamped its mouth shut to a nearly invisible line of shock, stopped only a few feet away from its prey. The rest of its body dangled to the floor below. Whimpering like a puppy, it slide off the small cliff and made its way to the largest stairwell where it crooned low in apology. Bumblebee, Bulkhead, and Arcee's horror returned when they saw who stood below.

A Cheshire fanged smile lit up, "Now, now, Casey, how can we be so rude to our guests? They didn't come for that fragment here to be eaten alive! We respect those who wander into our citadel, do we not?" A groan of forced approval bellowed from the train but it did nothing to oppose his master's words.

"Wait," Bumblebee interrupted, "Bendy?"

AN: The beginning of the unnatural relationship this is. Casey is the main OC here with tidbits of the Sheep and Little Ally Doll appearing later but throughout this, Casey lll will be the utmost important OC of the three (well five) of them. As you can see, there's going to be some surprises.
