This wasn't going to stop and Spring Lock knew it, as did the princesses, he had to defend himself. After the incident in Ponyville they came to the conclusion that Trevor was more than capable of attacking Spring Lock whenever he wanted now, he was toying with them and they knew it. But why; to instill fear? To make him feel worse about what happened so many years back? It was an accident yet, here he was, trying to get to Spring Lock and do something that even Celestia couldn't imagine. As Spring Lock marched to his old workshop the princesses followed close behind him, constantly asking him what he was going to do. He ignored then and continued to move with a determined look on his face. He may be old, but he wasn't going to to just let himself die.

He kicked open the door to the workshop and marched to the far back of the shop, using his horn to light the way. He eventually stopped in front of a large black tarp that practically blended in with the darkness around them. The princesses almost didn't notice it, it wasn't until they followed his stern gaze to the large plastic blanket that they actually managed to see it.

Twilight, being the most curious of the group walked closer to it and reach out to touch the tarp, only for her hoof to be smacked away by Spring Lock. "Don't touch it!"

Twilight grabbed her hoof and rubbed it before taking a step back. For an old stallion he could hit pretty hard. "What is it?"

Spring Lock sighed. "Celestia," The sun princesses eyes suddenly focused on the old stallion's form. "remember how I told you that I was working on my own private project before Trevor died? How I said I was working on something to thank him?"

Celestia nodded, remembering that horrible day in full detail. She used to have nightmares about it, so nothing about it ever escaped her. "Of course I do."

Spring Lock turned to face the three princesses who stared at him slightly out of curiosity. "Trevor had his own projects as well. I was the one who wanted to give foals a friend to play with, something that would make them laugh and smile. I was very lonely as a colt, I didn't have any friends, so I wanted to make sure nopony would ever have to be as lonely as I once was."

"Pardon my interruption, but where exactly are you going with this?" Luna asked, wishing he would just get to the point.

Spring Lock growled slightly at her, "Trevor was more than happy to help, but unlike me he despised children. He had more fun scaring them with his appearance than trying to be friends with them. It was very rare for him to show any sympathy toward them. I always knew he had a darker side to him, but I never thought he would be capable of becoming a monster...I digress though. Remember how everypony always wanted Trevor over for their Nightmare Night parties, Celestia?"

"I remember," She replied, "but I don't quite follow where you are going with this."

"I'm just trying to make you all understand." He explained, "They wanted him over because he could scare full grown stallions until they wet themselves, he was the very definition of fear on that holiday. He loved fear, not feeling it, but to instill it in others. He started working on his own project just as I did, only his was much more macabre. He wanted to create an animatronic that would show his love for Nightmare Night, that would show his love for horror." The tarp suddenly became engulfed in Spring Lock's magical aura. "Princess, I give you," The tarp was suddenly pulled away, "Nightmare Fredbear."

The princesses all jumped at the sight of it. It resembled Freddy, but barley, its body was larger and more round, but also twisted and evil looking. Its mouth had rows upon rows of sharp teeth and so did its midsection, it had long metal claws at the end of its hands, and it wore a bright purple hat and bow-tie.

"By the sun above, how could someone come up with something so horrible?" Celestia asked, having no idea what kind of pony it would take to create this for fun.

Luna leaned closer to the animatronic, "I do not understand why you're showing us this. What is its relevance?"

"It wasn't just made for scaring ponies," Spring Lock explained, "he wanted it to be more than just a toy for Nightmare Night. He programmed it differently from the others and gave this one defensive capabilities. He was going to use it as his own personal body guard. I can only hope that it wasn't meant to protect just him."

Twilight tilted her head in confusion, "Why would he do that? There are guards all around the castle. Why wouldn't he feel safe with them?"

"Despite what you might think, Trevor was relatively paranoid by all of the dangerous creatures here. He thought the guards here were too soft and could handle a truly dangerous situation. Honestly, with all that's happened here since he died, I can't say I blame him. He also had a number of trust issues, especially with the guard. They used to give him dirty looks all the time, even more so when he was around Celestia. He thought they were plotting against him and he knew he would be easily overpowered if they tried something against him."

Hearing these about Trevor slightly disturbed and worried Celestia. Had he really not felt safe in Equestria, even around her? "I had no idea he felt this way. If only he had just told me."

"He didn't want you to know. He figured that you had enough problems what with managing this, and I quote, Chaotic place and the magical city full of snobby douche-bags." The old stallion began charging his magic, hopefully he would have what it took to charge this beast of a machine. "This can go one of two ways. Either the animatronic will protect us or it will attack and set out to find Trevor, making our current predicament much more dangerous. You may want to take a step back. It if chooses the later then I would like it if none of you are harmed."

The princesses all looked at each other before stepping forward and putting a hoof in front of Spring Lock. "Please, allow us." Luna said, causing Spring Lock to lower his charge and let the royal family do their work.

They all turned their gaze over to the giant metal monster laying before them. After a confirming nod between them they started to charge the animatronic, letting a mix of golden, blue, and lavender colored magic seep from their horns and flow into it until a small charging symbol appeared on its chest showed that it was powering on. Once it was fully charged they cut off their magic and waited. Its eyes started to glow bright red as it hummed to life, looking up at them before getting up onto its feet; standing taller than Celestia, even having height over that of her long horn.

It scanned the area, recognizing the royalty that stood in front of it, however its gaze rested on Celestia. "Greetings Princess," It spoke in a disturbingly deep robotic voice, "It is a pleasure to finally meet you." It walked toward Celestia and lowered itself onto one knee, bowing to her. Its actions surprised the princesses, it seemed to show much more respect than the others, but they were meant for foals, their primary function was to be playful little critters. They had no idea what one that was meant to scare and protect would behave like. It rose back to its original standing position, "How may I assist you?"

Spring Lock pushed pass the princesses so he would be standing right in the animatronics line of sight. Its facial scanners instantly recognized the wrinkled unicorn. "Fredbear, what are your primary objectives?"

It's head looked straight forward as it started to reply with its initial programming. "Protect Trevor, protect Spring Lock, protect Celestia, scare any and all living things on Nightmare Night to the best of my abilities." Once it was done reading off its list of duties it turned its head back down to the ponies. "Where is master Trevor?"

Celestia and Spring Lock were the only ones who knew the full story of what had happened and explained to Fredbear in great detail what had happened. Luna and Twilight listened intently as well, however, the princess of friendship was beginning to find it difficult to hold her lunch and had a number of close calls as the story went on.

Spring Lock was forced to finish the story as Celestia found herself being almost impossible to understand through her sobs. Trevor's death still haunted her and a part of her still wanted to refuse that he was the reason for any of this, that he actually wanted to cause harm to Spring Lock. "So that's the situation. I feel that Trevor is seeking vengeance upon me for the horrible accident and I need your help. You are my last hope Fredbear; I think he's going to kill me."

"I find your story illogical in a number of ways. One does not simply come back from the dead Spring Lock, perhaps you are growing delusional in your old age. Even so, I will protect you and the princesses from any oncoming threat." The group let out a relived sigh as the animatronic agreed to guard them. "However, if your story is true and it is master Trevor, then I will not destroy him. My mission is to protect you all, Trevor included. I can apprehend and subdue him, but I am not capable of ending his life."

"I would expect nothing more. Perhaps if he is contained we may be able to-" Spring Lock was suddenly cut off as a loud bang echoed behind them.

They all turned to face the source and watched as the head of Bonnie, beaten and mutilated, skid across the floor to their hooves. Behind the sound of metal being dragged across concrete they could hear the sound of steel footsteps coming their way. Before long Trevor emerged from the darkness, dragging the body of an eviscerated Freddy behind him. He tossed the barely functioning animatronic toward them.

Spring Lock ran over to Freddy and looked him over, just like Chica, his battery had been torn out of his chest, Somehow, it was still clinging to life as it looked up at him. "Oh Freddy..." He muttered with a single tear running down his cheek as he watched the light in its eyes slowly die out. His horn lit up and a small teddy bear appeared in front of him. It wore a tiny black hat and bow-tie and had the name 'Freddy' stitched onto it chest. He gazed at the stuffed animal with a look of nostalgia and lowered it onto the lifeless animatronic. "You were always my favorite." He finished, looking up at the hunk of rusted metal standing before them.

"It's been a while, old friend. I'm honestly a bit surprised you managed to live this long. I knew better though, you weren't going to let something as simple as age take you. Well, now you won't have to." Trevor began to make his way over to the group.

Fredbear's facial scanners couldn't make heads or tails out of this things appearance, but despite the robotic distortion he recognized the voice as Trevor's. "So the stories were true." It said, walking in front of the group, causing Trevor to stop in his tracks. He didn't even notice Fredbear, until now that is. "I thought for sure the ponies here were becoming delirious, speaking about your death and resurrection."

Trevor chuckled slightly, "Of course, the only logical one of the group. It's a bit sad that I never got to activate you before all of this." As much as he would love to speak to his most favorite of the animatronics, he had a mission and he wasn't planning on stalling it any longer. "Step aside Fredbear, Spring Lock and I have some personal matters to discuss."

"You forget, Trevor, I can detect the hostility in your voice no matter how much you try to hide it." Fredbear explained, "I cannot allow you to harm Spring Lock."

Trevor didn't bother hiding it anymore, he knew better; He did make this animatronic after all. "Fredbear...you are my creation, you do as I say and get out of my way!" He demanded, his voice becoming deeper and much more robotic.

Fredbear's defense programming kicked in as he watched Trevor raise his fist and swing at it. It reached out and grabbed his wrist, stopping his attempt to assault it dead in its tracks.

Trevor may not be able to feel due to his robotic body, but he could detect the damage being inflicted on his arm just by the sheer grip of the animatronic standing in his way. He had forgotten just how strong he had made Fredbear, but that wasn't going to stop him. He pulled down with all his might on his captured arm, causing Fredbear to stumble. Taking this opportunity he drove his knee into the animatronic's chest, putting a dent in it right on top of its battery.

Fredbear's warning signs went off in its head as its battery cracked from the immense force. It could feel itself slowly beginning to lose power. Before it could react it was shoved to the ground and the next thing it knew, Trevor was on top of it, punching its chest over and over again.

It wasn't too hard to bring down the over sized robotic bear from hell if you knew how he worked. Being his creator, Trevor knew that Fredbear only had one weakness. In order to destroy him you had to attack him at his power source. It was a good thing he didn't have time to layer the metals like he originally wanted to, otherwise he would have been a goner. While lost in though he found himself being struck in the side of the head by one of Freadbear's large claws, causing him to be knocked several feet away from it.

Fredbear pulled himself back onto his feet, as did Trevor who was twitching wildly. That hit must have done some serious damage if this was how his body was reacting. However, it took its fair share of blows from him. Its battery was almost completely depleted from the massive amount of brute force that had been forced upon it. It tried move closer to Trevor but found that its legs had shut down, it didn't have enough power to walk and soon enough not even to stand. Fredbear gave Trevor one last death glare before its body shut down and it collapsed to the floor.

Trevor laughed as he turned to face the group of ponies who watched in horror as Fredbear was defeated. "You-you-you-you-you see?" He said, his voice becoming as glitched as his movements as he walked closer to them. "You can't beat-beat-beat-beat me! Did you really th-th-think that he could save you? I cr-cr-cr-creat-t-ted Fre-Fredbeard! I know how he wor-wor-wor-wor-works! My head may be a r-r-r-rotten sack of flesh, but I am not an idiot!" Luna quickly charged her horn and fired a magical beam at Trevor. He stumbled a bit, but held himself together. Suddenly five separate battery lights appeared on his chest, each one showing that it was almost fully charged. "Go ahead pr-pr-princess! You're only making this w-w-w-worse for you-yourself!"

The princesses back away, they wouldn't be able to stop him by force. They were not physically strong enough to take him down and their magic only fueled him. Twilight tried to teleport them all away but the stress of the situation was making it nearly impossible to focus.

Spring Lock bowed his head and sighed before walking over to meet the spasming animatronic hybrid half way. "Okay Trevor, you win. I'm all yours. Please just leave them alone, just take me."

"Spring Lock, no! You can't-" Twilight attempted to shout, but was cut off by Spring Lock's raised hoof.

Spring Lock lowered his hoof and looked up into the bright red eyes of the one he used to call his friend. "Just take me."

"Gladly." Trevor replied, grabbing Spring Lock by his neck and lifting him into the air.

The princesses began to stare intently and gasped in shock.

Spring Lock stared into Trevor's evil eyes. "Goodbye, Trevor."

His robotic face took on an angered expression as he spoke. "I am not Tr-Tr-Tr-Trevor. My n-n-name is Springtrap!" Before he could deliver the final blow he saw that Spring Lock's eyes had become very wide, but not at him. His head shot in the direction of the princesses who were sharing the same look, but for some reason they were all staring pass him. As if there was something...behind him. He turned around to find out what it was they were all so fixated on and immediately regretted every decision he had ever made. The shock that went through his mind was enough to make him drop Spring Lock to the ground. How could he have forgotten this? How could he let his blind rage make him completely miss a detail as important as this!?

Fredbear, now standing straight an tall, powered back on. It's red eyes shining bright and locking on to its target. "Primary power source damaged. Switching to back-up battery," It stated aloud.

Trevor looked up at the massive beast. "Fu-fu-fuck..." Was all he managed to say as Fredbear raised one of his large claws and slammed it into him with enough force to send him across the room and into a wall. The impact cracked the concrete structure and Trevor's robotic body fell into a sitting position, his head hanging down as if he were asleep.

Spring Lock slowly recovered on the ground, gasping for air. The princesses ran over to assist him. He assured them he was alright before looking up at Fredbear. "Thank you, friend." He simply said. "Thank you."

Fredbear didn't reply, it just stared down at the ponies and scanned them to make sure there was no permanent damage to any of them. "Scan complete, your vitals are returning to normal. However, I believe some rest would do you good."

Spring Lock chuckled at Fredbears comment, but there was some tension in the air. Celestia, after hearing that Spring Lock was okay, walked over to Fredbear and shot him a stern look. "I though you said you wouldn't kill him...You said you were not able to kill him because he was your creator!"

All eyes were now on Celestia and Fredbear. "I did not kill him." He replied, making Celestia's eyes grow wide with hope. "I incapacitated him. His batteries are unharmed, however he will face further glitches until his brain can recover from the trauma."

Twilight tilted her head at this. "Wait, what do you mean his brain?"

"Trevor's body is dead, but my readings show that his brain is still active." He replied.

They all looked over at Trevor's robotic form. He looked dead, but it was confirmed that he wasn't by the violent twitches he had every few seconds. The all ran over to his side, Spring Lock being picked up and carried by Fredbear so he would have to 'Stress himself further'. Once they got over Twilight cautiously reached out, but stopped just before touching him and look up at Fredbear. "Is it safe?"

FredBear nodded, "His reading show that he is unconscious."

Twilight gulped slightly before continuing, placing a hoof on his mask and lifting it. She gagged from the sight of his rotten flesh decorating a heavily damaged skull, but pressed on and continued to lift the mask until his entire head was exposed. She held her breath as she leaned over his body. What she saw defied all scientific possibilities. There it was, a perfectly normal, living, working brain with wires jammed deep into it. "I can't believe it..." Everypony now became focused on Twilight, they could practically see the gears in her head turning as her scientific mind started to work at a level that would frighten most geniuses. She turned back to the group and took a few steps away from Trevor's body. "Spring Lock, how have the animatronic that you've made manage to last so long?"

Spring Lock was a bit taken back by her sudden change and her questioning, but he figured it would be easier to just answer her than to start questioning everything himself. She was starting to look a bit frightening. "Well, I cast preservation spells on the exterior. It doesn't really affect the outside metals since they're constantly exposed to both air and weather, but I use it primarily to make sure the wiring, battery, and endo-skeletons won't fall apart due to age." At that moment, it was like the spring lock's in his head suddenly snapped together. "Wait, you don't think-"

"I do, in fact, I think a lot." She said before he could even finish his sentence."I think that your preservation spells completely preserved his brain." She said proudly.

"If that were true," Luna began, "then how come the rest of his body has decomposed?"

"Very good question, Luna. He said the preservation spell doesn't work outside the suit because it's constantly exposed to the elements. Therefore, when the suit started to rust and fall apart everything on the inside began to follow suit; no pun intended. However, the only part of the suit that has the littlest amount of damage is the head. With the jaw structure being the way it is it would allow air into the mask which made his face decompose with the rest of his body, but the top of it doesn't seem to have a whole lot of damage which would allow it to continue preserving the top portion of his head. So for the passed thirty years his brain has been in the same state since it died, making it continue to be fresh and able to be brought back with little to no repercussions." She explained, practically making the other ponies' heads spin. "See how these wires ended up digging into his frontal lobe? When we powered the suit it fed the power from the battery all the way into his brain."

"Allowing him to come back to life..." Celestia finished.

"Exactly!" Twilight put a hoof to her chin as her mind continued to come up with different theories and ideas. "Celestia, you were probably the closest to him other than Spring Lock, but then again Spring Lock knew him on a different level...Anyway, did either of you know him as being a very aggressive individual.

The two looked to each other and nodded. "Not at all. He was definitely strange and would act up sometimes, but he never let his anger get the better of him." Spring Lock commented.

"Mhm." Twilight hummed, turning her attention to Fredbear. "Fredbear, I want you to run another scan on Trevor, I would like to know what condition his nerves ending are in."

"Yes princess." It ran a quick but thorough scan on Trevor's body, finding little to no other living organisms within it other than the brain. "He appears to have none. They were likely damaged at some point, as of now they are complete decomposed."

"Perfect, everything is falling into place." Twilight muttered to herself.

Luna gave Twilight a concerned look. "Twilight, where are you going with this?"

She smiled at them, "Allow me to explain." The group let out a collective sigh to which she merely huffed at. "Anyway! When a perfectly healthy brain, much like the one currently in that suit, is subjected to something like this it can act up. When you take away one of it's senses it enhances all of your others. However, all of his senses were stripped away the second he died, not only that, but his body became almost completely decomposed, so he either way he lost everything. Sight, smell, touch, it's all gone. That suit is the only reason his brain can recognize anything, all of his sense are coming from that suit. That being said, the brain no longer has those senses. When you take away a sense the brain becomes hungry for information and enhances everything else. All of his physical senses were stripped away from him, leaving it to enhance the only thing he had left, his emotions." She waited a bit to let the information sink in. "Celestia, when he reached out to touch you that day and you withdrew, it hurt him a lot more than anything else ever could. Then when he walked away his mind pointed to the only one it could blame other than himself, that being the one who made the suit." Spring Lock's features sank, but Twilight continued. "When he had someone to blame his mind began to feed him intense amounts of anger. And think about this for a second; whenever he destroyed an animatronic he took their battery and put them in himself to give him more power. That power wouldn't just feed into the suit, it fed into his brain, making it more active and making it enhance those feelings." She paused for a moment to look back at the poor soul laying unconscious behind her. "He's not evil and he's not a monster, he's a slave to whatever emotion his mind gives him."

They all wore a melancholy look as the realization dawned on them. This whole time they thought he was lashing out because his death had changed him when really he had actually been fighting himself and suffering from something he could not control.

"There is a bright side to this story though." Twilight began, earning their attention once more. "All of this is happening because his emotions have been enhanced. Things like this happens to ponies in the medical field more often then you'd think."

Celestia's eyes suddenly got brighter. "Which would mean-"

"Yes, princess." Twilight replied, not even needing to hear the rest of her question, "We can help him. We just need to be there for him when he needs us and we need to be patient."

Trevor's mask suddenly slammed shut with a loud metallic smack and the lights in his eyes rebooted, tearing two large holes in the surrounding darkness.
