Wealth, Fame, and Power! W. D. Gaster, The King of The Pirates, had all those and the rest of what the world had to offer! Through many battles and trials, he had reached the pinnacle of the world's virtues and had nothing left but an illness that plagued him.

He brought himself in and was held at a worldwide public execution. Before he was executed, a man from the crowd asked:

"Where did you hide all your treasure?!"

To which the King of Pirates smiled and said:

"You want my treasure? You can have it! I left the most important treasure in the world on an island! Go and find it! 'For the next pirate that finds the UnderPiece, will be claimed the new King of The Pirates!"

Those were his final words before he was executed. He smiled to his death.

With those words, the world was flipped upside down as he created The Golden Pirate Era! People and already existing pirates from around the works started to sail the seas in search of the treasure that W. D. Gaster claimed to be-

The UnderPiece!

It had been Twenty Years since, and people have yet to find the treasure he was talking about. Except for one girl, who is now going to change the world by storm for the sake of her people.

This is the story of Muffet D. Baker and her way to becoming Queen of the Pirates!

Ralsei's eyes opened at this Susie girl's words. She saw her yellow soul glowing and it hit Ralsei right then, that maybe she is the next person to be on their ship.

According to the flag and the theory she had, a soul of incredible Justice was next in line to be a part of the Soul Parlour pirates! However, Retributive Justice?

She hadn't considered that there's be different kinds of Justice, it must depend on the person's belief in Justice. Each person's opinion on what Justice means to them is different.

Susie slammed her ax down, Lancer sidestepped and hugged the wall. The impact, broke the cement floor creating a rippling effect on the ground. Almost collapsing the entire room.

Ralsei spotted something. This room was flawed, the floor was able to be broken because it was cement, not magic darkness. This room was designed by Lancer, this was his room, of course, he wasn't thinking fully ahead for someone of his age.

"Oi, Muffet!" Ralsei said she had stopped herself a little. Did she really say 'Oi'? Her captain's vocab was rubbing off on her.

"Yo!" Muffet was trying to squeeze her head through the gate to escape.

Susie then slammed against the wall, trying to decapitate Lancer.

"S-Susie! Let's talk about this! I'm sorry, please-" Lancer pleaded, but Susie kept trying to cleave him entwine. He was a slippery guy.

"The floor is breakable! You know what to do from there!" Ralsei said while bracing herself by using some of her leftover Courage to make an orange bubble shield for herself.

Muffet smiled and winded up a singular punch. She slammed against the ground and the whole floor of the room concaved on itself. Everyone was falling into an abyss.

Muffet, Ralsei, Susie, and Lancer were plummeting into infinite darkness. They were all screaming for different reasons.

Ralsei was screaming in fear, Susie was yelling at Lancer out of anger, Lancer was screaming because he didn't want Susie to kill him, and Muffet was screaming because she loved the thrill of the fall.

"Imma kill you!" Susie said as she completely abandoned her ax and was trying to strangle him as they were falling.

"I just wanted to make my father proud Susie! It's really hard for me to do that! I'm sorry!" Lancer said flinching in fear as her hands were inches away from his neck.

Susie stopped.

"Be lucky I stuck around! Your mom didn't want to make two mistakes! Now get your bimbo ass up here!"

"I HATE YOU!"

Susie scoffed and retracted her hands. She looked to the bottom and saw a giant blue light at the bottom.

She looked at her new friend.

"Hey, spider girl, you're rubber right?!" Susie was practically calling a lifeline with that request.

Muffet thought about what she was going on about. Then it hit her.

"Aw Yeah!" Muffet said as she inhaled a bunch of air and bloated herself to the point where her stomach was the size of a giant balloon.

She then stretched her arms and grabbed Ralsei and Susie. Lancer just coughed up a parachute that had a symbol of a deltarune on it. He simply glided down.

When they hit the bottom, Muffet bounced off the floor lightly, protecting Susie and Ralsei. Muffet then reverted to her normal size and all three of them landed safely.

Lancer glided down toward the blue light. When all three of them adjusted, they had noticed that they were in a throne room. They had bounced and landed at the far end of the room away from the light. It was a very long and wide room like it was meant to host a ball for Giants.

At the end of the room, they could see that this was the room that held the fountain. They had made it to the fifth floor. All they had to do now was destroy the fountain, then fight the Chaos King.

However, it seems that their plan might have to change order.

"Dad! See! I brought them here for you, these mean people want to hurt you, but I know you're a good person right dad. Tell them that you've been a villain for fun but you're really a good guy!" Lancer said hugging his dad by his shin who was positioned on his throne.

"The heroes of light...three like the prophecy said..." The Chaos King spoke in a husky and deep voice. He was an enormous being, being 10"0 and on the fat side.

Lancer nodded furiously.

"Yep! Your son brought back all the people that wanted to harm you...all three! Now, this is the part where you guys talk it out cause there has been a huge misunderstanding...right?" Lancer was praying that they didn't have to fight, he always believed in solving problems with words. He still wasn't convinced that his father was as evil as they said.

The Chaos King patted his son's head.

"Talk...?" He then started to laugh a laugh that shook the room. Lancer was confused, why was he laughing.

"No son, there was never any talking...and what's this nonsense about being a villain for fun. Son, we are evil!" The Chaos King roared, which yet again, shook the room.

Lancer stood back scared.

"B-but that's what you told me..." Lancer started to sound hopeless again.

"Yes, that's what I said...because you're stupid enough to believe anything you're told! Why do you think I never let you inside the tree? It's because you were never worthy enough to stand in it! You don't breathe a sinister bone in your body, you're unfit to be a king after me! I'd rather die!" The Chaos King said with a serious and loud voice.

Muffet, Ralsei, and Susie clenched their fist. In rage.

Lancer started to stumble backward and he began crying.

"W-why dad-" Lancer tried to say before being interrupted by his dad.

"DON'T CALL ME THAT! IT'S DISGUSTING!" The King roared as he backhand punched Lancer against the wall of the room. Lancer coughed up blue blood and fell off the wall limply.

"TO HAVE SUCH A DISAPPOINTMENT CALL ME THAT IS REVOLTING!" The Chaos King was severely angered by his son.

Lancer crawled towards his dad.

"But dad...are you proud...?" Lancer tried getting atleast something out of his dad, but The Chaos King kicked him to the same wall. Lancer coughed up more blood, he was breathing heavily on the floor.

"HEY! STOP IT YOU ASSHOLE!" Susie said as she was readying her ax.

The Chaos King leaned down to his son and opened a book and shoved it in his face. The book was an even thicker copy of 'The Legend of Deltarune'.

"I WAS NEVER PROUD OF YOU! THE FOURTH PERSON TO AID THE HEROES OF LIGHT WAS SAID TO BE THE KING'S SON! HOW COULD I EVER BE PROUD OF- NO! EVEN LOVE YOU! DISGRACE TO THE THRONE!" He said as he tossed the book in Lancer's face and spat on him.

Bloodlust was consuming Muffet, Susie, and Ralsei.

"...You'd trust a book over your loyal son...?" Lancer proceeded to crawl limply at the question he proposed.

"HEH! ANYDAY! THE BOOK HAS BEEN MORE USEFUL TO ME THAN YOU HAVE YOU PUDGY PIECE OF SHIT!" The Chaos King said as he raised his foot and tried to squish Lancer to death.

When he completed the stomp, he felt like his foot was being restricted from fully killing him.

He lifted his foot to see that an orange dome was built over Lancer's body, protecting him from the attack.

Ralsei used the last of her courage to shield him from that attack.

The Chaos King stood there furious.

He didn't look too different from Lancer. However, the Chaos King was on thin ice from being obese. His gloves and hood were light blue. His cape was made out of the hardened darkness. He wore a crown of glowing light blue, his mouth was unbearable to look at. The weirdest thing about him was that he had a giant mouth on his stomach.

But the ugliest part about him was his chivalry.

Ralsei coughed up blood as her courage barrier shattered, the attack was so powerful, she had to use some of her energy and health to fully block it.

"HEH! SEEMS YOU MADE FRIENDS! BUT HOW LONG CAN YOUR FRIENDSHIP LAST YOU!" The Chaos King uttered before slamming his foot again.

This time, it was blocked by something more fleshy.

Muffet was holding up his enormous foot with her six arms.

Lancer looked up at her with the bit of energy he had, and she was smiling down at him.

"So dearie~ I heard you liked my spider cookies. I'll make you a whole batch once we leave, Whaddaya say?" Muffet giggled.

Lancer smiled slightly.

"JUST LET HIM DIE!" The Chaos King opened his mouth and shot a machine gun of Spades, a light manifestation of the Spade symbol on a deck of cards, at Lancer.

Before they could reach him, a barrage of spears came in at the same speed and canceled out all of the spades.

"So that's the story huh? You know what, that kid ain't that bad!" Said a familiar voice to Ralsei and Muffet.

The Chaos King looked up to see where the voice was coming from.

From the hole that Muffet made, Undyne came down on a board of bidents.

"Sorry I'm late guys, had to make a strange detour with Kris!" Undyne said looking at Susie at the last part of the statement.

"Where is he?!" Susie said with more concern than anger.

"I don't know, he said he had a plan but never actually told me. He's fine don't worry. Our job is to take down this fat sack of shit!" Undyne said with ferocity. Susie liked Undyne's vibe already.

Susie then looked at Lancer, bloodied and beaten...scared of his father that had caused him so much torment for years...

She knew that pain before...

Since she knows that pain, she knows exactly how to reciprocate it. Susie is brimming and overfilling with...

Retributive Justice!

The Chaos King was pissed that all his attempts were being warded off. As if he was entitled to take his son's life.

"ENOUGH WITH THE REUNION, NO ONE CAN STOP ME!" The Chaos King took out his stomach mouth's tongue. It was a long wire that had a spade at the end. He then whipped it as his son to cut him in half.

"Justice Form Number Two: Painful Retribution!" Susie roared almost as loud as the King as she used her ax to absorb the attack of the whip. She then swung her ax at him which he quickly used his indestructible cape to block. It knocked him back to the wall opposite of Lancer.

Muffet was proud of Susie's abilities and teamwork despite just knowing the people around her. She was a natural.

"Ralsei! Tend to yourself and Lancer!" Muffet yelled as she stretched her arms around Lancer and tossed it at her doctor.

Ralsei caught him, surprisingly, and ran further away from the fight and started to take out the medical equipment she kept under her green coat. It held wonders.

Before she could fully run away, she turned to them.

"Undyne! Muffet! I'm sorry, but I can only make these with the rest of what we have! Use it well, AND DON'T DIE!" Ralsei tossed two vials. One for Perseverance and Determination.

Undyne flew by on her board and caught both of them. She thanked Ralsei on the drive-by and flew quickly next to Susie and Muffet. She football tossed the Perseverance vial to her. The board dropped her off next to them.

In a line from left to right, it was Muffet, then Susie, then Undyne. In front of them, recovering from the attack was The Chaos King.

"Hey, captain..." Undyne muttered nicely.

"Yeah-" Muffet tried to respond to her but got smacked over the head with the spear.

"YOU ALMOST KILLED ME BACK THERE! I BROKE MY BACK!" Undyne yelled at her.

"I'm sorry! Geez!" Muffet said rubbing the back of her head, she hit her way too hard.

"Hey, guys...can you do me a solid?" Susie said seriously.

They both listened and nodded.

"I know you guys want to fight, I can't stop you from that. Anyone would want to kill this guy...but it's the same reason for...personal reasons...I want to be the one to end this fight...I feel like...I don't know...I'm meant to take this guy's life, for a little grudge I hold against myself. I want to be the savior this one time..." Susie said the most vulnerable and determined she could.

Undyne and Muffet both knew what she was talking about. In a deeper sense, this was her fight. They both knew that they weren't even supposed to be there, this was a story for Kris and her. They humbly agreed to her conditions.

"Thanks, guys, I see that the original plan has gone out the window...seems we need to beat him within...twenty minutes," Susie said thinking hard about what time it was.

"Why?" Muffet said rubbing her chin.

"It'll hit night in twenty minutes, if we don't beat him by then, the roots will be too strong and healthy for us to stop entirely, making everything we do here useless. We need to beat him and destroy the fountain before it can give the roots nutrients. If the fountain goes, everything else will!" Susie hoisted the ax over her left shoulder.

Muffet and Undyne laughed and got into a stance.

They were on a timer.

The Chaos King laughed.

"No matter how many numbers you stack up, soon, I will reach a level of divinity that the world has yet to see. I will become invincible! A god! You can only rely on yourself in these seas!" The Chaos King was enveloped in this weird purple and black aura. The aura of true evil.

Ralsei had checked Lancer's soul and it seemed that he had Kindness as his soul, however, she didn't have any vials of Kindness left after StarDrop island.

She could tend to him, but most of his wounds were fractures in his bones. She couldn't tend to it right with all the rumbling, she was unsure of what to do.

Lancer was slowly digging into his pocket and took out a whistle. Ralsei's eyes widened.

The energy of the whistle stopped the tension between the two sides they all paid attention to the silver mouthpiece Lancer held in his hands.

"Everyone...I'm sorry!" Lancer started crying waterfalls. He was biting his lip to not let out sighs, so much so that he even gritted his teeth together between sentences. He was trying to be a bigger man here.

"I was an idiot! I believed that maybe...I could have friends if I had just shown off my dad's fortune and everything my dad had to offer! But I was wrong!" Lancer wiped off his tears that seemed to endlessly flow.

Muffet turned to Lancer and started smiling, so did Undyne. She let out a grimy chuckle.

Susie just looked at him in silent awe. So did Ralsei.

"Now I know that all I had to do was...*sob*...be myself! Not what people expect me to be! So many times I *sob* was abused and treated like scum because of an association that I was proud of! I'm sick of it!" Lancer used his other hand to slam on the ground in anger at himself.

"You guys have given me something no one has ever done...something my family hasn't given me...*sob*...you gave me a chance!" Lancer held his free forearm over his eyes to try and stop his tears.

All four of the heroes of light smiled wholesomely.

"Thank you! All of you!" Lancer said shrieking into the throne room.

The Chaos King was scared of the whistle, the Jester was ordered to defend anyone who called it, even if was against another member of the tree. All he had to do was blow it and the battle was decided.

"S-son! Y-you can be King, I was just joking...we joke with each other. Come on, put the whistle down and we can discuss this, Father and Son!" Said the Chaos King, scared of the whistle and the person arriving if it were whistled.

Lancer looked at the people around him, and they all gave him hopeful eyes and a soft and honest smile.

"Shut up fatso! That last strand of hope that's vengeful...burns through blood! Enough of the jokes! I'm my own man now! You know what...?!" Lancer yelled at his father.

The Chaos King's jaw dropped. The four heroes of light started laughing hysterically, they were proud of the little guy, they all decided to play along.

"What~?" All four heroines said.

"...Was my theme song...cool?" Lancer said wiping off the last of his tears.

They all laughed in a giggle.

"Yeah, man! It was the best thing I heard!" They all said one after another.

Lancer smiled, he knew he was making the right decision.

"I'm glad...it's my deadbeat father's turn for my final chorus...MAKE HIM SING!" Lancer said as he slammed the whistle on the ground, breaking it instantly.

Lancer was filled with...

Overwhelming Kindness!

A giant wave of green washed over his body and completely healed his wounds.

They all heard his wishes loud and clear. The three heroes got into a stance and readied their weapons.

Muffet, her fist.

Susie, her ax.

Undyne, her Bident.

The Choas King started cackling.

"I hope you know, that whistle was the only way you can defeat me!" The Chaos King continued to cackle until he got cut off.

"If you think you can beat those three heroes of light by yourself, you're the Jester here!" Ralsei said from across the room.

The fighters started laughing in his face.

"Well! You guys just wasted five minutes being idiots! How do you plan to defeat me in even less time?!" The Chaos King raised a brow to them.

Undyne held up her vial in her left hand, Muffet held her vial in her top right hand, and Susie was surrounded with a yellow aura while holding the ax above her head. They were in perfect symmetry.

"Like this!" All of them said simultaneously.

Muffet and Undyne squeezed their vials and broke them. Engulfing them in a beacon of purple and red light. Susie's overwhelming sense of Retributive Justice matched her partner's aura intensity.

It was a wall of purple, yellow, and red. Opposing them was a thick blackened aura.

Here it was.

The showdown of light and dark.

The battle between The Heroes of Light and the Chaos King of Darkness.
