Author note: one part of my own connected FNAF universe.

Bonnie found himself flowing in a dark void. He looked around until he saw it. A blue light that looked be some type of barrier. He had seen this barrier many times before as a child. He knew what was on the other side it and knew what would happen if it broke.

He noticed a small crack appearing in the center of the barrier. His eyes widened as he could see glowing purple eyes staring back at him. He knew what this meant. It was trying to escape and if it was successful then everyone around him would be in danger.

"NO!"

A roar echoed throughout the empty void. He had to do something fast before the barrier breaks completely. There was no telling what that thing could do.

"Hey bro, wake up!"

#

Bonnie woke up to see his younger brother TB standing over him. Bonnie lightly pushed him aside. The two brothers lived together in an apartment not far from the pizzeria where they both worked. TB titled his head to the side at his brother in confusion.

"Why are you in my room," Bonnie asked.

"You weren't getting up," TB replied, "I heard your alarm going off."

Bonnie looked at the alarm clock on his nightstand. He was five minutes late getting up this morning. He got out of bed to get ready for work. TB was walking out of the room behind him.

"Did you get back late from your date with Chi last night?"

"No, I got back when I said that I could."

"Then why were you late getting up?"

Bonnie remembered his dream. Was it really a dream or was he really seeing that thing trying to escape? He wasn't sure which it was. He could only imagine what would happen if it did get free. He looked over at his brother as he was throwing his guitar case over his shoulder.

"Hey TB," he called, 'what would you do if you know who escaped from mom's barrier?"

TB froze at the question. He looked over at his brother with horror on his face. Bonnie knew that he still remembers what that thing could do. He had seen it back when they were kids.

"Is…. he trying to get out," TB asked nervously.

"I don't know," Bonnie replied, "I had a dream that the barrier was breaking."

If TB's face could then it would have turned pale at the thought. Sure the creature never hurt him, but he knew what it was capable of and boy it was terrifying.

"You know what never mind," said Bonnie, "forget I said anything."

He grabbed his guitar case and walked toward the door. TB watched him walk to the door. If that thing did get out then there was no telling what could happen. TB knew that there was nothing that could it once it was let free.

#

Bonnie and TB arrived at the pizzeria. Bonnie pushed the door opened to see at the others were already there. TB walked in behind him trying to act like his usual goofy self.

"Hey gang," he said.

"There you two are," said Freddy, "you're late."

"Sorry about that boss," said Bonnie, "kind of overslept."

"You were busy with my sister last night weren't you," Chica teased.

Chi's cheeks turned pink at her sister's comment. Bonnie rolled his eyes at Chica. TB sneered at that until his brother glared at him from the corner of his eye.

"Never mind that now," said Freddy, "come on we get a show to put on."

"Right," they all replied.

#

Bonnie felt strange all day. He stood on the stage doing his best to put on a good show. He heard a growl in his head. He knew that could only mean one thing. It was getting free. He noticed that one of his eyes had changed to the creature's vision.

Damn it, it is coming out.

The toys were performing on the other side of the room. TB had noticed that one of his brother's eyes had changed to the creature's. He knew that wasn't good. Bonnie blinked as his vision was back to normal. He tried to play it off as nothing, but he knew that it wasn't. the show ended and the curtain closed.

Bonnie could hear Foxy and Mangle starting their show next. Freddy and Chica were too busy talking about how well that went. Bonnie knew that they didn't notice what happened with him. He was relieved to know that they didn't see.

"Bro," TB called.

Bonnie turned to face his brother. TB gestured o his own eye. Bonnie knew that he had seen it. He hoped that no one else had noticed. The toys walked toward them. Chi walked over and kissed him on the mouth. He returned the kiss as he felt his worries slip away.

Leave it to his girlfriend to put his mind at ease. They heard the pirate show end meaning that the day was over. Chi wrapped her arms around Bonnie's torso as she snugged to him. He could hear the creature inside of him let out a soft purr.

"Good work everyone," said Freddy, "let's clean up."

"Got it," everyone replied.

#

Bonnie and Chi were cleaning in one room while everyone else was handling another. Chi would take any chance to be alone with him. Bonnie held his head as he could hear the creature growling his head. He felt a hand on his shoulder. He looked over to see Chi standing there giving him a worried look.

"Are you alright," she asked.

"Yeah, I'm fine angel," he replied.

"You've been acting strange all day. Are you sure that you're okay?"

"Yeah, I'm fine."

Chi didn't buy that. She knew that there was something wrong with her boyfriend. She knew him better than that. Bonnie knew that she wouldn't buy it. She knew him too well for that to even work. He finished his job and let out a sigh. Chi had just finished her job and grabbed his hand. He looked at her thinking that she wanted to make out like they normally would if they were alone.

"Are you sure that you're okay," she asked.

"Yeah, I'm fine," he replied.

"Bonnie, please tell me what's going on."

"It's nothing angel."

He knew that he couldn't tell her about what was going with him. He couldn't risk anyone knowing about the beast inside of him. He had to call his mother about this when he gets home tonight before the barrier breaks completely.

#

"What am I going to tell Freddy,." TB asked.

Bonnie had decided to stay home today as he was going to call their mother to come help with his problem.

"I already told him that I'm not feeling well," Bonnie replied, "just go with that if anyone asked."

"You know that Chi would want to come by to see you after work."

Bonnie knew that as Chi would come over whenever he was sick and take care of him. Bonnie loved that about her, but he couldn't that happen this time.

"Tell her that it could be contagious."

They both knew that wouldn't stop her. Chi would go through hell for him if she had to. TB sighed before walking out of the door. Bonnie picked up the phone to call their mother, but unfortunately he only got her voice mail. He sighed as he left a message before hanging up the phone. He put his hands to his face.

He could hear the monster growling in his head. He felt himself falling forward onto the floor. He dug his fingers into the carpet. He could feel something inside of him shatter. He knew that meant that the barrier had completely broken now.

"Damn it," he swore, "he's free."

He waited for something to happen, but nothing did. He wondered if it was exhausted from breaking the barrier. He sat up onto the floor looking up at the ceiling. What could he do now that the barrier was broken. He knew that meant he had to watch himself with the others for now on.

#

"Really, Chi, my brother's okay," said TB.

"If he really was then he would have come into work today," said Chi, "now open the door."

TB groaned as he knew that Chi wouldn't listen to him. When it came to her boyfriend: she didn't fool around. He unlocked the door, and they stepped inside. Bonnie was lying on the couch looking up at the ceiling. He looked up to see them enter the apartment.

TB gave him an apologetic look. Bonnie wasn't surprised that his girlfriend would come over to check on him. She walked over to him. He sat up on the couch as she sat down beside him.

"How are you feeling," she asked.

"I feel a little better," he replied.

"That's good to hear, I was worried."

"I'm doing just fine angel.

Both brothers knew that Chi would stick around if Bonnie needed her. He did like it when she came over to take care of him. He felt like she was his wife with the way that she treated him. She reached up to touch his forehead. He maybe an animatronic but that didn't mean that he wasn't immune to diseases.

"You don't have a fever," she said, "that's good. Why don't I make dinner tonight."

"You don't have to do that angel," Bonnie replied, "we're good here."

"Nope, I'm making dinner tonight."

She stood up and headed to the kitchen. The brothers knew that she wouldn't listen. TB sat down onto the couch beside his brother.

"Did you call mom," he asked.

"I did, but I haven't heard anything back yet," Bonnie replied, "also, he broke through."

A look of terrier crossed his face. Bonnie knew that he was concern of what could happen just like he was. TB looked over at Chi. How would she react if she knew what was really going on with Bonnie. Bonnie was having the same thought. He was scared of she would think if she knew about his dark side.

"We just have to make sure that you don't lost your temper," TB murmured.

#

After dinner Chi decided to spend the night. Bonnie laid in his bed with her snugged close to his side. He looked down at her as she slept. He was afraid to fall asleep. The creature could come out and could hurt her. He couldn't bare the thought of hurting her. Chi moaned in her sleep as she snugged closer to him.

He stroked her head tenderly. How could she react to see the beast that was hidden deep inside? Would she look at him the same? Would she be afraid of him? He couldn't bare the thought of her rejecting him. She was the one thing that he couldn't live without. He leaned down and kissed her on top of the head.

"I love you angel," he whispered, "I hope that you never find out about my darker side."

#

Bonnie could see it staring back at him. He sat up in his bed. The creature looked down at a sleeping Chi that was still curled up to him. Bonnie held his breath as the creature reached down and gently stroked her cheek.

"Beautiful," it said.

"Don't touch her," Bonnie shouted.

The creature looked up at him and snarled. He watched as it leaned down to kiss Chi on the cheek. Bonnie was shocked to see this. He knew seen this thing show anything other than rage and aggression. This was something completely different.

The creature glared up at him before it stepped back into the shadows behind it. Bonnie looked down at Chi to check to see if the creature did anything to her. He sighed with relief to see that she was fine. He leaned down and placed a kiss onto her cheek.

"I promise to protect you from myself," he whispered.

#

Bonnie walked around the pizzeria the next day. He knew that he couldn't afford to stay home for long. his dream kept replaying in his head. why did his dark side act that way toward Chi? He hadn't seen it do that before.

He looked over to see his best friend: Foxy and his girlfriend: Mangle sitting at pirate cove talking. He looked over to see Freddy and Chica with their three kids. BB and JJ ran around the stage room playing a game of tag. The puppet and Golden Freddy were talking off to the side. Fred and TB were chatting on the small stage where they would stand on during performances.

He looked around but didn't see Chi anywhere. He wondered if she was in the kitchen. She could be in there cleaning the kitchen. He was about to walk toward the kitchen when something caused him to stop in his tracks.

He held his head as he fell onto his knees. He could feel something clawing out to the surface. He let out a loud scream. The others looked over to see him on the floor. Chi came running out from the kitchen to see him on the floor.

"Bon," Foxy called as he ran to his side.

"Bonnie," Chi cried out.

"S-stay back," Bonnie roared as he screamed.

He got down onto his hands and knees as his body began to change. TB stood there frozen with fear as he knew what was happening. Bonnie cried out as his teeth grew sharper as sharp claws shot out from his fingertips.

"Everyone get back," the puppet ordered.

Chi didn't listen as she reached out her hand toward him. Bonnie roared out as the transformation was complete. TB ran over and pushed Foxy back to prevent him from getting any closer.

"Bonnie," Chi called.

The creature looked up at her as it breathed heavily. It stood up revealing the beast that stood there. The creature snarled at the others. The puppet and Golden Freddy jumped into action and went on the attack. The creature reached out and grabbed them both by the throat. It roared before slamming their heads together.

It dropped them to the floor. Freddy ordered the others to get back. Chi stood there looking up at the creature that use to be her boyfriend. The creature looked down at her. It took a step toward her. TB saw this and called out to the creature.

"Nightmare Bonnie," he shouted, "don't do it!"

The creature stopped and looked over its shoulder at him. TB stood there waiting to see what it would do now. The creature let out a low growl at him. TB knew that it recognized as its little brother. The creature turned back to Chi.

Chi was backing up to the wall behind her. The creature walked toward her. She felt her back hit the wall. It reached out and gently touched her cheek. She looked up at its eyes. They were gentle and kind just like Bonnie whenever he stared at her.

It touched her cheek and gently stroked it. She reached up to touch its cheek. The creature purred under her touch. She smiled up at the creature. It was still her Bonnie.

"Bonnie," she said.

"N.B., " TB called, "please don't…."

He stopped as he noticed that he wasn't hurting her. Instead, it seemed to be in love with her like just his brother. The creature leaned forward and kissed her beak. She wrapped her arms around its neck as she returned the kiss.

They pulled away staring into each other's eyes. The pulled back as it let out a roar of pain. It fell onto the floor face first. Chi got to her knees at its side. The puppet stood there with Golden Freddy at his side. Chi watched the creature turned back to Bonnie.

"TB, what was that," Foxy asked.

"I'll explain later," TB replied.

#

"You mean to tell us that Bonnie has two personalities," Freddy asked.

"Yeah," TB replied, "the one that you all know very well and then there's Nightmare Bonnie or N.B. as we call him."

"How long has this been a thing," Foxy asked.

"Since we were kids."

"Why haven't said anything about this," Freddy asked.

"We didn't think about it," TB replied, "our mom had managed to lock up N.B. or so we thought. It came out yesterday."

"Was that why, he was acting weird as of late," Chica asked.

"Yeah, I'll never forget when I first saw N.B.," said TB putting his hands to his head, "I was in the first grade and was on my own home from school when these older kids jumped me. They beat me pretty bad that day. Bonnie showed up and saw what they did do me. He was so mad, madder than I've ever seen him and that was when he first turned into N.B., after that our mom had to seal him away as he was dangerous."

"I can't believe it," said Foxy, "this whole time he had this and we didn't know."

"What now Freddy," Chica asked.

"I don't know," Freddy replied, "I just don't know."

#

Chi was sitting in the back with Bonnie. The puppet had to chain him up in case that creature came out again. Bonnie moaned as he opened his eyes. Chi gasped as he saw up or at least he tried to. He looked down to see the chains around him.

"Bonnie," she cried throwing her arms around him.

"Chi," he said in surprise.

"I was worried."

"What happened?"

"You don't remember? You turned into some strange creature."

"Crap he got out. Did he hurt anyone?"

"You did send the puppet and Golden Freddy flying."

"Crap."

"Bonnie what was that thing?"

He sighed as he knew that he had to tell her now. N.B. had come out and revealed himself to the others. He wouldn't be surprised if they were scared of him now. He told her everything that he knew about N.B. which wasn't much.

He waited for her to yell at him, asking not he didn't tell her before they started dating. He could imagine her deciding that it was too risky for her to stay with him. He could see her breaking up with him as she was scared of what he could do to her, but instead she didn't say anything. She wrapped her arms around him as she hugged him, which surprised him.

"I wish that I knew sooner," she said, "I'm so sorry that you had to go through this on your own."

"Chi…"

"If I knew sooner then I could have helped you."

"You aren't afraid?"

"Why would I be afraid of my own boyfriend," she asked as she pulled away from him as she stared into his eyes, "what kind of girlfriend would I be if I leave you when you need me."

"Chi…"

"Besides, he seems care for me like you do," she explained, "I'm too worried."

"Thank you, Chi," he said pulling her into another hug.

"I'll always be there for you, Bonnie. I love you."

"I love you too."

The door opened and they pulled away to see the puppet and Golden Freddy entering the room with a pink bunny right behind them. Bonnie was relieved to see his mother standing there.

"Sorry, it took a while," said his mother, "I was busy."

"Your mother and brother explained everything to us," said the puppet.

"I'm sorry that I didn't say anything about this," said Bonnie.

"What understand your reasoning," said Golden Freddy, "something like this can't just be shared so willingly."

"Agreed," said the puppet, "you have to be careful of who you share this information with."

"Unfortunately, with the barrier broken," said his mother, "nothing can be done about N.B."

"What should we be on the lookout for in the future to make sure this doesn't happen again," Golden Freddy asked.

"Well, anger can trigger the transformation, but he has to be beyond angry for it to occur. Also, if you what you said it true then it's safe to assume that it has a soft spot for Chi just like my son does. N.B. usually shares the same emotions toward his loved ones as Bonnie does."

"So, watch his temper," said the puppet, "he won't harm us?"

"Not unless you are the cause of his rage," she mother replied, "also, keep me posted if this happens again."

"Got it," said Golden Freddy, "are you sure that you can't reseal N.B.?"

"I'm afraid not, once the seal is broken it can't be sealed away again."

Both Golden Freddy and the puppet looked at each other. This could prove to be difficult and getting use to.

#

Bonnie's friends had been careful not to trigger N.B. but so far it rarely showed its face. It did appear whenever Bonnie was in danger or any of his friends. They had learned when Bonnie had transformed: Chi was the only one that could keep N.B. in check.

Bonnie was playing his guitar as Chi approached him. She sat down on the stage beside him. Bonnie had just finished the song that had been practicing for a party tomorrow.

"How are you feeling," she asked.

"Okay, I guess, I'm really sorry about N.B.," he replied, "I never meant for you to find out about him."

"Don't worry about it. He's a big a cuddly rabbit toward me anyways."

He chuckled at that. He knew that N.B. had a soft spot for her just he did. She wrapped her arms around him as she snugged to him. He set his guitar down at his side. He was grateful that she didn't run away from him. He knew that she would always have his back no matter what.

"Thank you angel," he whispered, "for accepting my dark side."

"I love everything about you," she replied, "even your dark side. I love you."

"I love you too."
