Okay my first crossover I'm posting on this site! Yay!

VERY, VERY, VERY, VERY, VERY IMPORTANT! Read this before reading the story!

This story is a special crossover. If there are any of you who don't know, and I feel like there will be a lot, I made a fnaf trilogy and it is that trilogy that is being crossed with Undertale. I do highly suggest if you haven't read them, to do so before reading this, but I know that some of you won't want to. So this is why I am writing this little important note. Basically if you don't want to read my fnaf trilogy at all, I have basically summarized the most important things to know about in this chapter. Basically it is nothing but retelling my three fnaf stories as quickly as I could managed. So you can read that if you want a brief understanding on who my fnaf characters are basically. But again I suggest you read my fnaf stories, which starts out with Facing the Past. But I have also written this so far in a way for you to understand who my fnaf characters are without too much confusion.

If you are someone who has read my fnaf trilogy, all the summary will be in italics, that why it will be a bit easier to find when the actual story begins, unless you want to read the summary. This chapter is majorly just a quick recap on all that has happened with Nick, Mike, Danny, and everyone else. The actual stuff doesn't happen till like the very end.

So yeah, you all have your options. Either read my fnaf trilogy then read this or just stick with the fast summary of them. Or, if you have read them, skip to the end or just read the summary for fun if you want.

END OF IMPORTANT STUFF:

Okay, well now that I have said all that, I hope you all enjoy this. I'm mostly doing this for fun. And in case fans of my trilogy are wondering, no this is not cannon to my fnaf stories. This is just something I wanted to do because I thought it would be fun. And so far it is. I'm going to also upload the second chapter soon, maybe before the day is over. If not, it will defiantly be up tomorrow some time.

Well with that all finally said, enjoy Breaking Reality! Also trilogy fans, look! It doesn't start with "Facing the..." It's a miracle!

Fazbear's Family Diner was the number one family restaurant in the entire town. Children and their parents would pack their ways in the small building in hopes of the delicious meals and the fun furry animatronics that would sing funny and cute songs. The owner of the building Fred Fazbear was a proud man because of his success and he shared in the success with his only son Luke and nephew Danny. It was always a wonderful day for those three. However, their happiness was not to last.

Luke, a bright young teen, loved the two popular animatronics dearly. Fredbear and Spring Bonnie also returned the feelings. They looked at Luke as well as his cousin Danny as part of their family. The four were just as close as Mr. Fazbear was to them. So it shouldn't come as a shock that Luke decided to ask the oldest robotic animal a small request. He wanted to wear the bear's suit and have a feel of what it is like to be an animatronic.

Fredbear, not seeing anything wrong with the idea, agreed, and all too soon, Luke was inside the spring lock suit. It was all so cool and amazing for the young teenager. He was so excited he began to jump around in joy. That is when everything went wrong, terribly, terribly wrong. It started with a loud snap. And Luke instantly knew something was wrong. Then the pain came. It attacked his body, wave after wave as each sharp metal end came thrashing and piercing into his body. Nothing he could do would stop the attack. The pain became too great until finally, the teen collapsed in a pool of his own blood.

It didn't take long for his body to be discovered by his father and cousin. The shock was too great for the two humans, as well as the animatronics. Fredbear blamed himself and Spring Bonnie grew cold and angry at the bear. But it was clear that Mr. Fazbear and Danny took it the hardest. Both became just as cold and angry as the rabbit, but none showed it more than Daniel.

He hid away, he lashed out, he completely gave up. His parents tried to reach out for him, but after many failed attempts, the poor teen just snapped. He attacked his parents and hurt them to the point they needed to go to the hospital. That would be the last time young Daniel Fazbear saw them. Years went by and Daniel hadn't gotten any better. He would lean off his uncle's success to get by, but when he wasn't mooching off of Mr. Fazbear, he was hiding himself away even more. Each day drew him farther into the darkness and closer and closer to his insanity. Then one day, he snapped again.

It started with a little boy who he noticed ran away from his older brother. So in an attempt to help him, he tried to bring the child back home. But when the boy annoyed him too much, Daniel grew angry, and when he became angry, his insanity began to crawl around inside of him. He couldn't stop himself as he managed to corner the child to an empty street. His annoyance only grew when he noticed just what building the boy was trying to get inside, the diner. Feeling his insanity reached its peak, Daniel Fazbear attacked. When he left, all that was left was a motionless heap on the ground surrounded by the dark red liquid.

With the death of that child, came the death of any hope Daniel had to becoming like his old self again. Now all that was left of the once happy teen was a monster filled with bloodlust. Many others would suffer because of this monster. Five other children to be precise.

Five children, all just wanting to celebrate a birthday party, but this purple suited monster had other plans for them. The birthday boy and girl, a set of twins, thought they were in for a treat when they and their friends were pulled aside by a furry yellow rabbit, but the second they laid eyes on the creature hiding away inside, they knew there was nothing they could do before they suffered the same fate as the first child back at the diner.

Years went by and Daniel once again hid himself away. Since the beginning of his crimes, he was caught only once, but because of the wealth of his uncle and the fact that the children were proclaimed as missing and not dead, he was able to escape his prison life. But he basically made his own home a prison, only leaving to buy food and such, then spending the rest of this days locked in darkness. The only thing keeping him going was his own madness.

Back at the new restaurants, even more tragedy was beginning to take place. The children, even though they have long since passed away, still lived in their own ways. Haunting the second establishment and eventually the third one that would pop up. Being children, you would think they would be happy and full of energy, but no. Because of the actions of Daniel, they grew just as angry as he was and filled with the need of revenge. The problem, they could not remember Daniel's face. So the best thing they decided to do, kill off every night guard who came in until finally they found him again. The only way for them to do this was to possess the loving animatronics.

The leader of the ghosts, the very first child, took over the puppet while the other five took over the five oldest animatronics, excluding Spring Bonnie. Once they were probably prepared, they went on the hunt. They killed many night guards, but none of them ended up to be their killer. The first ghost was growing anxious. He was desperate to find the man who murdered him, but luck just never seemed to come.

And all the killings were taking their toll on the animatronics. Freddy, the leader, did his best to stay strong for his robotic family, but it was clear the guilt of killing innocent lives was getting to all of them. He, Bonnie, Chica, and Foxy would grow quiet, barely putting their all in their acts both before and after the Toy versions of themselves were made.

Because of the dark atmosphere the ghost children had been creating, it didn't take long for the third building to be set up. Freddy and his gang continued to be the main cast and the Toys were unfortunately put away. Also forcing the ghost leader to stay away from the night guard hunt. Of course just because they lost their leader, the children continued to work just as hard to find their killer.

Everything continued on like this for more years until finally a new night guard showed up. Mike Schmidt. A young man who has had his own history with the Fazbear establishment. He started out when the third building was first opened up. He met Freddy and his friends and instantly made a strong bond with them. He would visit them constantly, and each day their bond would grow stronger until the boy basically became like a part of the Fazbear family. However one day Mike had to move away and the animatronics were forced back into their dark routine. It wasn't until the boy reached the age of twenty that he returned and even gained the job as the night guard in hopes of earning the money he needed and seeing his old robot friends. Just imagine the shock of his first night when his childhood friends tried to hunt him down and murder him.

The animatronics tried to help him as best they could, but the ghost children were relentless, trying all they could to capture and kill the freaked out guard. He managed to last until the end of the week that Mike decided enough was enough. He confronted the first murdered child, doing all he could to prove to him that he was not the killer. And to his shock, he succeeded.

With tears in the child's eyes, he ended up hugging the guard, crying away all his pain and sorrow since his death. Very soon the other children would join in, and Mike did the one thing no other guards managed to do. Ease the murderous children's minds. Days went on, and Mike would continue his job while getting along with the children. All seemed happy, but there was just one problem that they would face. Daniel.

Daniel, still suffering because of the mistakes he had made, decided he had enough, and thought of a wild and crazy plan to get rid of his nightmares for good. And while he started to work on his plan, one of the ghost children, a boy named Shawn, was unfortunately relapsing in his anger. His need for revenge returned and the first thing he decided to do was attack Mike, no longer believing the guard was innocent.

The first child did his best to help Mike, all while Daniel made his move. He ended up meeting Mike and after seeing just how much the ghost cared for him, took the young man hostage. Mike would fight, but he was basically helpless as Daniel kept him prisoner.

While Mike was being held captive, the once again revenge filled Shawn, bought mayhem back to the pizzeria. He forced the other children to work for him while also making the newly awaken Toy animatronics to work for him. And how unfortunate it was when two past workers were dragged into the mess and wound up the new prey for the angry child and possessed animatronics.

After all this took place, it wouldn't be long until these two situations crossed paths. Daniel snuck Mike around, basically using him as a shield against any possible attacks while Shawn did his best to kill off the past employees that were forced into the chaos.

It didn't take long for Daniel to cause trouble while in the building, catching the ghosts' attention before they could hurt the other humans. They went to investigate, finally facing their killer for the first time after many years.

Daniel looked at them, shaking in fear as he took notice of their furious gazes. In hopes to keep them away, he threatened the still captive Mike. It seemed to work and they ghost children slowly began to back off. Feeling confident, Daniel slowly started to escape, but Shawn wouldn't have that. He tried to stop the man. In shock, the killer began to wave his weapon, a small gun, around wildly.

Before anyone could put a stop to this a loud bang filled the room. With large, shocked eyes they children and killer turned to face a stiff Mike. The guard slowly looked down and noticed the globs of blood beginning to drip down his chest. He gave one last look to the children before his knees buckled and he collapsed on the ground.

In a matter of seconds, the very first murdered child grew furious. He pushed past Shawn, glaring down at the killer with all his pent up rage. It didn't take much convincing for the first child to get the others to back him up.

Knowing he was basically screwed, Daniel made a fast attempt to flee. He ended up finding the old and broken version of a familiar animatronic, Spring Bonnie. He gave a laugh, thinking the suit would be the best way to hide from the enraged kids, and slipped the robotic suit on. How was he to know that simply laughing would set off the inner locking inside, forcing the sharp jagged metal to pierce into his body, all too similarly to his deceased cousin, Luke.

Soon after Daniel's death, Mike was laid on a table and surrounded by the crying children. They prayed for him to wake up, but with one final goodbye, Mike closed his eyes for the last time. It all seemed to be the end for the kids. The only human who managed to befriend them was dead. They wept as quietly as possible, thinking they would never see their friend Mike again, but then a miracle happened.

A new ghost floated behind them, a fond smile forming on their faces. He called out to them and it only took a few seconds for the six of them to tackle him down in a large group hug.

Despite passing away, Mike was happy. He felt he didn't leave much behind, so he had no worries being trapped in pizzeria with the children as well as the animatronics. He was finally surrounded by a loving family.

Unfortunately there was one last obstacle they all had to go through, and once again it consisted of the purple suit wearing man. Like Mike, Daniel had also returned as a ghost. And he was even more furious than ever. He made a new plan, a plan to destroy every Fazbear building ever to exist in one last hope of getting rid of the children once and for all.

And for the longest time, his plan was working. He gained helpers, creatures created from his own new found ghostly powers, he forced old human 'friends' to help him, until his way would prevail. Everything was going according to plan for what felt like days.

It started with destroying the robotic part of the odd family. One by one, each animatronic was taken down, and the ghosts could do nothing about it. Then went the diner. With the help of a human on the outside, Daniel managed to destroy the old building his uncle had created so long ago, in a fiery explosion. It didn't take long for the second building to go. Leaving only the third pizzeria and a newly bought Fazbear's Fright.

But when there was only three animatronics left and the ghosts, they finally managed to change the tides around. The small allies Daniel had switched sides, the destroyed animatronics were quickly fixed up as best as they could be, and Daniel found himself surrounded. So in one final desperate attempt, he made a break for blowing up the building they were in. Unfortunately for him, the others stopped him.

But no words they spoke to get through to him would work. Even when the ghost of his dead cousin returned and tried to talk some reasoning back into the insane purple killer, it wouldn't work. Once again it all came down to Mike knocking some sense into him, just like he did for the children his first week. In this case, however, he was literally knocking the sense into Daniel. Hit after hit, Mike told the killer off. It wasn't until he noticed his words finally broke through that the guard stopped.

Knowing that Daniel failed, he told everyone for them to go away, leaving the stunned Daniel by himself. However it didn't take long for him to emotionlessly destroy Fazbear's Fright and sealing his fate of being stuck with everyone else in the only remaining building of the establishment.

Days went by, and Danny began doing the one thing he knew he was good at, hiding. Every time someone would try and find him, he would vanish. The ghost of Luke worked the hardest in trying to find Danny, with the help of the repaired Fredbear and Spring Bonnie.

However it wasn't those three who finally managed to locate and even talk to the killer, it was none other than his first victim. The child approached him, and doing something that would finally change the way the killer thought. He forgave the man for all the pain he's caused the child and the others.

To say Danny was shocked would be an understatement. Danny had never felt so confused and conflicted in his entire life. The very people who should be hating him for all eternity…had forgiven him. It was then a giant weight was lifted off his shoulders. He collapsed in front of the children and cried. Finally letting go of all his anger and pain. He knew he didn't deserve it, but these children still accepted Danny as part of their insane family.

And that, my lovely readers, is when our story finally begins. It begins with Nick, our wonderful first ghost child, and a typical day after all that insanity took place.

"Ugh…" Nick groaned in boredom, while glaring/pouting over at Mike. "Mikey! I'm tired of waiting!"

"Nick, I told you, I have to work."

"No you don't!" the child pointed out very stubbornly.

The night guard sighed and rubbed his eyes. "Look, I still have my job here, so yes, I do." He stood up from his chair and walked over to the child before picking him up. "Nick, listen, I promise as soon as I finish my shift, we can play all day."

"Promise?"

"I promise." Mike smiled and ruffled the boy's hair, much to the child's annoyance.

"Gah! Seriously!? Why do grownups do that!?" Nick complained while fixing his hair. Hopping out of the guard's grip, he huffed and began to leave the small office. "Fine Mikey, I'll wait…But you better keep you promise."

Mike just laughed as he returned to his seat. "Yes sir."

Nick giggled at that before walking away finally. He floated over to the main room for the pizzeria, finding all the relaxing animatronics and other ghosts there. He grinned and approached Danny from behind. Once he was properly behind him, the child let out a loud scream.

"AH!" Danny yelped, jumping out of his seat. When he heard the mocking laughter of the boy, he growled and sharply turned his head to face him. "NICK!"

"Hi Danny! Want to play?"

"No, I don't'."

"Aw…why not?" Nick pouted and floated up higher to be eyelevel with the man.

"Because I'm not in the mood." Danny pointed out, returning to his seat. "Especially after you did that little trick…"

Luke chuckled form his spot and looked at Nick. "Sorry about him pal. Danny is just a stick in the mud."

"Yeah, he's a jerk."

"I am not!"

Nick rolled his eyes. "Says the man who killed me…"

"Eh…" Danny lowered his head in shame and turned away. "J-just go play with someone else brat."

With a sigh, Nick agreed. "Fine…you're being a jerk again anyways…"

"You little…"

"Danny…" Luke spoke up in a warning tone.

"Hmph!" the old killer huffed and crossed his arms.

Rolling his eyes again, Nick decided to approach someone else. That's when he heard it. Laughter. Bright and giddy laughter. "Huh?" He looked around, trying to decide which of his new family was making that noise. None seemed to be laughing, which further confused the child.

"Nick?" a faint voice spoke up, breaking the child from his thoughts.

"Huh?" He looked over to see one of the other children looking at him. Her name was Sammy and was the twin brother of Shawn. She smiled softly and extended her hand. "Do you want to play a game with us?"

He looked down at her hand for a moment before looking over at the other remaining kids. "Uh…"

Suddenly he heard the laughter again.

Gasping, Nick began to look around. "Do you hear that Sammy?"

"Hear what?"

"That!" The two grew quiet, listening around them carefully. Nick noticed the soft giggling was coming from one of the hallways. He pointed dramatically at the location for Sammy to look at. "There! It's coming from over there!"

Sammy blinked in confusion, not hearing the noise at all. Before she could comment this, Nick ran away, determined to find out where the sound was coming from. "Ah! N-nick! Wait up!"

Hearing the commotion, Freddy approached along with Fredbear and Spring. "What's going on?" the brown bear questioned.

"It's Nick. He hears something."

"What?" Fredbear demanded confused. He looked off at the hallway the boy had ran down, trying his best to listen to any odd sound.

Spring huffed in annoyance and began to follow after him. "What are you idiots waiting for? Let's go find him before he gets himself in trouble."

The two bears agreed and followed after the rabbit, the other ghost children close behind. Noticing the group leave, Danny stood up out of curiosity and quickly joined them as well as Luke.

Nick meanwhile ran down the dark hallway as fast as he could, doing all he could to find the source of the noise. "Hello?" he questioned out loud. "Is someone there?"

He reached the end of the hall, but the odd laughter wouldn't go away.

A deep frown was quick to form on his face. "Hello!?" He screamed out, cupping his hands over his mouth in an attempt to be louder.

"~Hello~" a voice called out. What spooked the child was that the voice came from inside his head.

"Wh-who was that?"

"Don't worry Nick. All will be made clear soon."

"Where are you…?" the boy questioned, suddenly feeling very frightened for some reason.

"You know? It's very odd we are talking Nick. I never expected this from a reset. Never."

"'Reset'?" Nick repeated, still very confused.

"Yes, but no matter. I'll work with this. I don't mind at all. I don't know what happened to them, but I don't really care." The voice let out a loud giggle again. "So since they are gone, will you help me now Nick? Will you be my new partner?"

"Partner?"

"Yes. If you accept, just open that door to your left."

"Wha-" Nick looked over and sure enough there was a door he was sure never existed before. "What's going on?"

"Just open the door Nick. And we can start."

The child could faintly make out his family's frantic voices, but the mysterious giggling drowned them out. "I…I don't know…" he waited for whoever was talking to him to speak up again, but they didn't. "I…I…" He looked around, never noticing just how dark the end of the hallway really was. All he seem to be able to make out was the mysterious door.

Something inside of him told him to ignore this. To just walk away and never have to worry about whatever was going on again. But for some reason he felt drawn to the door. He felt like he needed to know what would happen if he were to open it. He felt…determined to find out. So with a small gulp to calm his nerves, he grabbed the knob and pulled the door open.

Slowly he stepped inside, not recognizing the room he was in. "Wh-where am I?"

Suddenly the door slammed shut and Nick jumped in fright. He felt tears form in his eyes as he looked around in fear. "Mikey? Freddy?" He called out in hopes of one of his family members being there. "Anyon-"

That's when he heard a loud snap. He looked down, gasping in shock when he notice the floor beginning to crack and break under his feet. He tried to float up to avoid standing on the fragile floor, but he couldn't.

"Huh? What's going o-" Suddenly the floorboards all broke away, leaving a large hole under his body. He let out a loud scream of fright as he felt himself being dragged down into the darkness. "AAAAAAAAAAAAHHHHHHHH! MIKEY! SOMEONE! HELP ME!" He called out for help.

The darkness enveloped him, not leaving a trace he was down the freshly made hole.

The happy giggling returned after all that. "~But nobody came~"

And there you have it! The first chapter of my Undertale and Fnaf crossover! I hope those who haven't read my fnaf trilogy aren't too confused. I'm going to try and keep characters like Nick as simple to understand as possible. And as for fnaf characters I haven't really brought up much, I'll be describing important stuff about them as the story goes on.

So who could that voice have been talking to Nick? Hmm...oh it must be so difficult to figure it out! Haha, anyways, yes, Nick was definitely talking to someone very important to the Undertale universe. It will be only a matter of time before we hear from them again. hahaha!

Well I don't have much else to say now. I basically got all I wanted to say at the top. So I'll end this here!

Until next time! Bye! And don't forget to review!
