Billy, who sit down in an empty dark room, after a moment of Michael Afton closed the door.
Billy hesitated, giving it as it was done, finally over, but yet... he felt it didn't...
He didn't wanted to stop what he was doing. Entertain children... Cook pizzas... Cook and prepare cakes for birthdays...
He didn't wanted to all of that to just... end...
But he couldn't do anything about it. He knew he couldn't, as after all... what was left for him? What was left for him to do?
He didn't had anywhere to go, Michael was clearly throwing Billy away, and Billy knew he didn't had anything left. He abandoned Henry without any warning, and the last thing he knew... Michael had to be right. And so... Billy decided to rest, as he really did what he had to do, and he was glad for it all... The MCI resting in peace, finish William for good, make Cassidy cooperate with him to take William soul... He did what he had to do, and he is proud of it all, and without any agony, he decided to let the remnant melt for a last use... For his peace to be achieved...
As his human body inside the suit started melting, a sudden red light suddenly appeared at his right. He turned to look, noticing Shadow Bonnie in the shadows, placing down an arcade. The arcade's screen was turned on, and from it, a red glow, and then, a sudden reflection of a red beam was shot to Billy, impacting him and pulling him inside the arcade.
In other place, Frisk was playing Princess Quest IV, but up of them, was Helps lurking in the shadows, and it then jumped, but Frisk easily moved back and dodged Helpy. Frisk hesitated, looking at Helpy, and after a second, Helpy suddenly started yelling and having some sort of spam. Frisk hesitated, wondering what was that for, but behind them, Vanny slowly appeared, and managed to slash Frisk in their left arm.
Frisk tried to punch Vanny with their right hand, but the scissors of ScrapBaby moved to cut and grab Frisk's arm, but in a sudden, the Princess Quest IV arcade's screen had a red glow, and shot Billy out of it.
As Billy was shot out of the arcade, he also noticed where he was being shot into, and he quickly landed kicking ScrapBaby and grabbing her scissors hand with both hands, and with some difficulty, he maga Ed to break ScrapBaby scissors hand.
Frisk hesitated, but Billy didn't, and he quickly, punched Vanny, sending her to fly back. Billy then turned to look at Frisk, and quickly grabbed them up to hold them with both arms against his chest.
Billy then started running, and quickly, Glamrock Freddy appeared following Billy.
Glamrock Freddy: "Way to go, superstar! And you, thanks for the help, who are you?"
Billy: "Is not the time for presentations, focus on not being overwhelmed."
Then, everything changes, the background changed into different locations of pizzerias, a factory, and other places, as they kept running.
After a short moment, the background stopped changing to a workshop factory on fire, debris falling everywhere. Billy's pupils changed from being green with red, into green with blue; Billy looked around, searching for an exit, while continued holding Frisk, and Glamrock Freddy reacted worried for what was happening, but Billy simply ignored whatever Glamrock Freddy was talking about.
Glamrock Freddy: "Oh no, everything is collapsing. Quick, we have to find an exit!"
Billy then jumped, getting through the debris with ease, and getting out, but as Billy was in mid air, everything changed again, now being a down part of the Murray's workshop factory where metal is being melt. Billy and Frisk looked down, noticing they were going to fall in a big bucket of melt metal still melting, and without hesitation, Billy there Frisk away, falling alone in the bucket.
As Frisk was thrown away, everything changed again, landing on Glamrock Freddy's stomach hatch.
Glamrock Freddy: "Here you are, superstar! I was worried for where you could have go, but don't worry, now you don't have to worry anymore, as-"
Then, something started happening inside Glamrock Freddy's stomach hatch, as Glamrock Freddy's pupils changed to hollow purple. After a short moment, Frisk reached to kick the stomach hatch and geting out badly injured.
Frisk ran to escape while Glamrock Freddy was chasing them, but then, the place changed again, and from a wall, a sudden wave of animatronics broke it down, running to chase Frisk too.
Frisk continued running, until a moment later, went to the left, going to another hallway. The animatronics quickly followed, but then, as they continued running down the hallway, a strange convenient lamp was in the edge of the turn, and Frisk walked out of being behind the convenient shaped lamp, sitting down.
After a short moment, Puppet flied, and stopped to be in front of Frisk while holding the necklace, and after a second of staring each other, Puppet simply flied through the hallway, leaving Frisk there.
Frisk fell down, to lay down from exhaustion of everything, but couldn't catch a break as everything changed again as they started falling down. Frisk turned to look to where they were falling, and was at the end of the Princess Quest minigame.
When Frisk was about to land, they are suddenly blinded by a sudden gold shine glow from the left, and then, catched up while they can't see. After few seconds, Frisk is placed down on the ground, and with high difficulty tries to look, it was Billy, but he was now 60% bigger and more golden and brightful than before.
Billy kneeled down, placing his right hand over Frisk left shoulder.
Billy: "Are you alright, little pal?"
Frisk hesitated, staring at Billy's eyes glowing with a green color. After a short moment of hesitation, Frisk nodded.
Billy: "That's good to know..."
Billy then got up, and started looking around, noticing the place, and the torches off.
Billy: "This place looks weird. Those torches are under... I'm unsure of what those strange little structures are behind each torch, but I also wonder why there are masks too... I don't understand, but... I have a feeling of... Something not being right..."
After a short moment, Frisk started walking forward, but then is pushed back by Billy while also in the same instant, there is a sudden collision. Frisk looks up, the golden glow now against a dark flame purple, and then notices Billy and Springtrap hands against each other, both pushing in the collision.
Springtrap: "Fascinating. You are something above the others. Unlike the rest, I cannot control you."
Billy: "I recognize your voice... Wait, you're not William, right?"
Springtrap: "Ah, so you recognize me. That's delightful. At least you're aware of who I am."
Billy: "I killed you twice! This time, I'll make sure you don't get back up!"
Springtrap: "I don't remember you killing me, but I dare you try. I ALWAYS COME BACK."
Billy: "Yeah, you do, but uglier each time. But I know how to kill you with ease."
Springtrap: "Oh, is that so? I invite you to try then."
Springtrap was slowly winning the clash, pushing Billy back, but at the same time, Billy's hands were also glowing with a white bright light that was covered by the golden glow of his entire body, and Springtrap is hands were slowly cracking.
With a quick move, Billy pulled Springtrap closer, and punched him in the face with his right hand, sending him away, but Springtrap recovered quickly and started floating while shaking his head.
Springtrap: "We're only starting. You'll fear me, as everyone else does."
Billy: "I doubt anyone would fear you, now come to fight!"
Billy was focused on Springtrap, while Springtrap was still mocking around and feeling he was having the upper hand. Billy's pupils changed to green with a red circle.
Springtrap hesitated, floating around, trying to see an opportunity, and then, teleported and rushed to attack them from behind. Billy turned around, and Springtrap then got punched by something that made him fly away, crashing against a wall. Billy hesitated, turning to look at his right, noticing Puppet.
Billy hesitated, in complete shock, feeling as he could cry as the last time he saw Puppet, was after Fredbear's PizzaWorld exploded, having her in his grip of what remained of her.
While Billy hesitated staring at Puppet, Puppet floated slowly towards Frisk, offering two gift boxes, and both opened, in the left the princess' sword, in the right the locker fixed and as brand new.
Billy: "Charlie, you're-"
Puppet moved her left hand, placing a finger in the mouth of Billy, doing a gesture to shut up but on his mouth instead of her own. Billy hesitated, changing his look constantly between the finger, her left hand, and her face.
Puppet: "I don't recognize you, but you're confusing yourself. I don't know how you know my name, but that doesn't matter now."
Billy: "... B-but... sigh... Yeah, you're still the Charlie I remember... Even if you died, and I clearly remember getting out of the debris... I guess whatever happened that brought me here... May have also brought you too..."
Billy then grabbed Puppet's left hand, and moved it away.
Billy: "Even if you're as I remember you be, you're not my Charlie."
Then, debris fell down, and the three turned to look, and Springtrap floated higher.
Springtrap: "I see, so you were also brought from somewhere else... That explains why you're different to every animatronic. And why you're SpringBonnie, the exact same springlock suit that I have been trapped for 30 years. But that's alright, that makes this much more fascinating."
Then, purple portals started appearing everywhere, from where animatronics started coming through.
Springtrap: "This is my world, all here is mine. And even if you two are not from here, your so lovely Charlie is mine too."
Springtrap then moved his right arm forward while opening his right hand. And a black smoke with fade dark purple on it started surrounding his right arm and hand.
Springtrap: "And so will you two soon."
The animatronics hesitated, waiting for the order. The three prepared themselves for the battle. All started with Springtrap shooting a black smoke blast with fade dark purple against the three, Billy jumping, Puppet floating, and Frisk dashing, the three dodged with ease, but all the animatronics started to rush.
The battle started.
All the animatronics quickly reached them, but only attacked Frisk and Billy. Both were on their own in their parts, while Puppet floated to fight Springtrap.
Both Billy and Frisk easily handled their parts, the animatronics, despite outnumbering them, were way weaker than each on their own.
Meanwhile, Puppet floated near Springtrap, both staring at each other.
Springtrap: "You again. I had enough of you getting in the way. You don't know how difficult you made everything to be."
Puppet: "This ends here, Mr. Afton."
Puppet then flied towards Springtrap, and their fight started, but for much Springtrap tried to hit Puppet, he couldn't as the way Puppet flied and floated made her dodge everything with ease, apart of Puppet already be hard to hit for the type of body the animatronic has as design.
After a moment, both Frisk and Billy were finished with the animatronics, and both stared for an instant at each other, and then a sudden black smoke blast impacted in between of them, making both turn to look, seeing Springtrap being more and more annoyed while trying to hit Puppet, until he was done by frustration, and needed to make an army of virtual glitch rabbits to appear to can win, and only then, Puppet finally fell, overwhelmed by the virtual glitch rabbits.
Springtrap: "Finally. I was done of you getting in the way, and annoying me by making all more difficult than had to be. But no more."
Springtrap then turned to look at Frisk and Billy, and then raised both arms while ascending up slowly.
Springtrap: "Now I just to finish with you two. I have to admit, you two will be harder to tear apart, but we'll see how many time I put you apart, before you can't be put back together."
Frisk hesitated, preparing themselves, while Billy seemed enraged as his pupils were now red.
Billy: "You put yourself high, but what is high is your fall. You want to test it? Then get down here and do it instead of saying. No more talking, fight. us."
Frisk hesitated, surprised by the sudden shift, but understands it, and decides to remain prepared for the last fight. Springtrap also hesitates, slightly annoyed by the mockery, but accepts to a direct confrontation, as teleports and instantly punches Billy, who blocked the punch.
Both then started the fight.
Springtrap teleported, trying to overwhelm Billy, but Billy easily reached to defend himself against Springtrap.
Each punch, blocked. Each blast, dodged or jumped.
Springtrap couldn't reach to hit Billy, until suddenly when he tried to hit Billy, Billy blocked and countered him, sending him to Frisk, who stabbed him with the princess' sword, making a light blast be shot from the top of the sword after the stab.
But suddenly, he glitched, and all went darker, and Shadow Bonnie and Shadow Freddy appeared, and Springtrap absorbed them both, and everything got consumed by the darkness.
After a moment, everything started to light up slightly, the only lights being Billy, Billy's pupils, and the princess' sword.
Both hesitated, staring at each other, until everything shaked. Both looked, seeing Springtrap now being huge massive. His appearance being more darker and with a shadow body with a sinister body with a dark purple constant flame covering his body.
Both prepared for the real last battle, and quickly, a lot of virtual glitch rabbits appeared, and all started flying towards both, but Billy quickly went to Frisk, grabbing them to put them on his back.
Billy: "Grab tightly, we need the sword to finish him off."
Then, he quickly jumped, quickly reaching high altitude, while moving to wall to wall, trying to dodge and evade the virtual glitch rabbits from bitting him, even kicking one as another while dodging and jumping.
But as Billy jumped here and there, Springtrap made platforms and walls appear and move in sudden instants, trying to make Billy can't dodge, but Springtrap didn't really know how to use the Nightmare Mode power, what ended being a help for Billy to can dodge more unpredictably, instead of being a disadvantage for him.
As Billy jumped around, he eventually reached to be near Springtrap is head, and started dodging the virtual glitch rabbits, to kick them and impact them on Springtrap is head, making them explode one by one on Springtrap's is head.
After a short moment, Billy launched Frisk at Springtrap's head, and Frisk quickly stabbed Springtrap in the forehead with the sword, making him have cracks over his body, which cracks after a second started to open and drop yellow light from them.
Billy fell down, and stood still while observing. Frisk hesitated, turning to look at Billy, and then jumping, and Billy catched Frisk and placing them down while Springtrap was slowly cracking more and more, until he eventually exploded with a blind yellow light, but even that light was still having a flame dark purple shadowy smoke covering everything.
The battle didn't finish yet, and in a sudden, something suddenly kicked Frisk sending them far away and crash against a wall.
Billy hesitated, surprised and worried, but Frisk was perfectly fine, it was just pure strength with no real damage, as Frisk easily moved out of the small crater they did on the wall.
Then, Billy felt something, and turned to look, but got punched on the face, barely moving him. Springtrap looked more broken than ever, but still Springtrap with a now shadow body and in NM. But Billy remained standing still, careless of that punch.
Billy: "You're not the only one who brought anyone to the battle."
Springtrap hesitated, wondering his next move, while being in desperation, and taking steps back.
Billy moved, standing sideway with his pose to his right while staring at Springtrap, and then, a fadeful silhouette was being seen, with their backagainst Billy's, in same position but in the opposite direction... Cassidy.
Billy: "Ready?"
Cassidy: "Ready."
Then, both charged, quickly starting to combo Springtrap. Both fought alongside, their coordination surprisingly near perfection.
Billy started by punching Springtrap, then Cassidy grabbed Springtrap's head and jumpscared him, and Billy punched his face making him take a step back, and Cassidy pushed him against Billy, who lifted his right leg to kick Springtrap's right knee in the side and making Springtrap fall to knee down but quickly kicking Springtrap in the face.
Cassidy then punched Springtrap's face, making him be pushed to the other side, and Billy kicked Springtrap in the torso, sending him to fall down, but Cassidy pushed Springtrap up before touching the ground with his back, and Billy quickly grabbed Springtrap's right leg and crashed him down to then spin and send him to crash against a wall.
Springtrap crashes against a wall, but is quickly combo'd by hallucinations from Cassidy while Billy jumps to get impulsed. When Billy jumps, gets impulsed and lands a kick burst kick on Springtrap, making the wall tremble and break, and Billy jumps doing a backflip while Springtrap is sent to fly and crash against another wall.
But before Springtrap crashes against the wall, Cassidy pushes him back, and Billy started comboing Springtrap by punches and kicks, breaking his ankles by the kicks. And then, Billy did a flip and kicked Springtrap in the head making Springtrap flip around while being pushed to his left, and Cassidy grabbed Springtrap and crashed him against the floor to then force him to be carried around while eating the ground, until a short moment later be pulled to fly away.
Billy grabbed Springtrap mid air, and then landed down kneeling and moving Springtrap down, making Springtrap's back be broken as Billy's right knee impacts on Springtrap's back, and then, Billy quickly moved and kicked Springtrap, sending him away, and Cassidy punched him.
Then, both started to make Springtrap be sent back and forward to one and another, comboing him together, while also making the walls and ground be used for crash Springtrap against at.
The place started to break and slowly fall apart, but both didn't care and continued, while Springtrap started to also crack.
Both continued comboing Springtrap, moving in synchronization and as if both were dancing together in the rhythm of the battle.
Billy punched, and then Cassidy flied to punch or push Springtrap, and then Billy again punched or continued the combo differently. But both continued by each punching once and letting the other move to punch.
After a big while, Springtrap crashes against a wall, but Cassidy grabs him and pushes him towards Billy, who grabs his head firmly. After Billy grabbed Springtrap's head, Billy's eye sockets glowed blind white light, while his palms also glowed blind white light. Springtrap was unable to move, and Billy's grip started making overheating Springtrap's NM form, as he was melting Springtrap down.
Slowly, Springtrap's head started cracking from the sides to the center, more and more, while Springtrap couldn't defend or even move at all. After a short moment, Springtrap's head was severely cracked, until suddenly, Billy managed to overheat Springtrap, getting his head out of the NM, and in the same instant, Billy also instantly melted Springtrap's head, and also crashed it with his hand.
Springtrap body remained still for a second, before falling down, falling and losing the NM, and then, it collapsed.
Then, everything went back to the room where the Princess' Quest IV was, Billy hesitated and noticed how he was't glowing with that golden light anymore, but as his original golden color. A gray near white portal opened, and they turned to look at it, but then Billy turned to look at Frisk.
Billy: "I'm glad you're fine, even if at the end you didn't really need me. I simply couldn't let a child getting hurt."
Billy then flexed his left arm making his left arm grow up, and gave a thumb up with his let hand.
Billy: "If you ever need me again, I'll be there if I can. Have caution, little pal, even if you don't really have to worry about anything. You never know for what you're ready and for what you're not."
Frisk hesitated, and turned to the grey near white portal, and started walking towards it. And then, a sudden red beam was shot from the arcade, impacting Billy's back, and pulling him back in. Frisk hesitated, glancing to peak, but when Billy dragged into the arcade, Frisk turned back to continue walking towards the grey near white portal.
Back at Billy, he got back to the empty dark room he was, pulled back there, but crashing against a wall and falling to kneel down.
Billy hesitated, and then after few second, he walked to the middle wall where he was sitting at the beginning before being pulled the first time into the arcade, but then noticing there was not arcade anymore.
Billy hesitated, but was proud of being capable of have gave himself a last use for the last time, moving to rest in peace, knowing he just did and always did the best he could ever do, inside all he knew he had to do.
And then, his pupils flickered and then turned off, and his human body started to melt down.
After a moment, Billy's human body melted inside the suit, the Puppet's mask now pinned in the wall above Billy's head with some space up from Billy with both eye sockets also dark and empty, and a fade invisible balloon floating up from Billy's body.
