(Power of Neo [TemTale ver.] plays)

TT!Kathy and TT!Temmie run towards Judgment Hall. A very angry TT!Mettaton Neo chases them.

"Darling! I know that being held captive is not the idea I have in my mind... but it will suffice!" TT!Mettaton Neo yells as he launches a yellow beam from his cannon.
TT!Kathy and TT!Temmie dodges the attack. This sent the trio into a battle.

"I don't want to marry you! How many times do I have to tell you!?" TT!Kathy asks out of anger.

TT!Temmie launches white pellets towards TT! Mettaton. The attacks look like fireworks. TT! Mettaton dodges before attacking the duo with flying boots. TT!Kathy dodges his attack, but TT!Temmie does not dodge in time.

"Temmie!" TT!Kathy cries out.
She choose "Fight". TT!Kathy use Flareon's powers. She used another Flamethrower.

"Darling... You are testing my patience." TT! Mettaton sounded furious after it hit him.

He launched a double beam. One from his eye and the other from his cannon. TT!Kathy grabs TT!Temmie to have a higher chance at survival. The attack lasts a bit longer than the previous.

"Temmie, is there a way out of this hall?" TT!Kathy asks with a plan forming in her mind. They luckily are not hit.

"Yes. I can get out of here by fleeing. Why do you ask?" TT!Temmie answers, but did not attack.

"I need you to flee. Bring the syringe here as fast as you can." TT!Kathy said thinking quick on her feet.

"I don't want to leave you." TT!Temmie whined.

"You have less health than me. Go! I will be fine." TT!Kathy assures her.

"Um... Okay! But don't lose." TT!Temmie hesitates. She eventually runs away from the fight.

"It's just you and me darling. I don't want to hurt that cute face of yours." TT!Mettaton pouted.

"I know this isn't you, Mettaton. Try to fight the dark magic!" TT!Kathy said with hope.

"Fight it? No darling. I can finally see clearly." TT! Mettaton said sounding scornful.

TT!Kathy chose "Fight". She launches a Will-O-Wisp at him, but misses.

"Then I will fight, until you go back to the way you were." TT!Kathy said strictly.

TT!Mettaton looks at his health. A few more hits and he is done for.

TT!Temmie is now outside the zone and looking frantically for the syringe. She could not hear the battle nor the song anymore.

"Where is it?" TT!Temmie asks herself multiple times.

She frantically looked through the drawers that are there. TT!Nick casually walked in on TT!Temmie.

"What are you doing?" TT!Gaster asks her.

"Ack!" TT!Temmie had a small heart attack. She tumbles backwards. TT!Nick lifts her up when TT!Temmie can't get back on her legs.

"Look I am really sorry about this whole situation I got you and Kathy in. I thought I was doing the right thing. But, I have learned from my mistakes." TT!Temmie said to TT!Gaster sounding very apologetic.

"... So, where is she?" TT!Gaster hesitated a bit. He is unable to tell if they could trust her.

"She is fighting Mettaton who is in his Neo form." TT!Temmie said honestly.

"That explains why I feel someone is using more magic than usual." TT!Gaster mutters.

"How can we fix Mettaton from his corrupted SOUL?" TT!Nick asks. He places TT!Temmie down.

"I am looking for a syringe that contains light magic. It should, hypothetical, cure him." TT!Temmie said. She fails to realize that there is no way TT!Nick could have known that TT!Mettaton has a corrupted SOUL.

"Let's look for it then." TT!Nick said sounding content. He looks for the syringe in various drawers.

"...Hey. I'm-I'm super sorry about fusing with you and causing you to end up like this. Can-Can you ever forgive me?" TT!Temmie asks sounding terrified.

"... I blamed you for so long. When we were fused together I felt the anger you had for me and those who helped. I did not mean to experiment on the Temmie kind if it led to this. I did not know that Chara and Frisk were going to use you for their own nefarious purposes. I should be the one apologizing." TT!Gaster said looking at TT!Temmie.

TT!Temmie smiles and wags her tail. She jumps into TT!Gaster's arms.

"I forgive you." She said sounding happy.

"I forgive you, too." TT!Gaster said hugging TT!Temmie tightly.

TT!Nick managed to find the syringe. He let the two have their little moment. TT!Nick enters the hall.

(For the Fans [TemTale ver.] plays)

There he saw TT!Kathy being pinned to the ground. TT!Mettaton uses his noodle arm to hold her by the throat. TT!Mettaon stood above TT!Kathy when he had a good grap. His cannon began loading itself with dark magic.

"Soon we shall be together." TT!Mettaton said with a wild smile.

TT!Kathy struggles to free herself. She thought about doing an absurd action. She stops wiggling and TT!Mettaton's grip starts to chock her. TT!Kathy gasps for air. TT!Mettaton hesitates on launching the beam. He realizes what he is doing. Panicking, TT!Mettaton releases his grip on Kathy. The song ends.

"Darling?! Are you okay?!" TT!Mettaton asks as he is about to comfort his future wife.

TT!Nick teleports behind TT!Mettaton and injected the syringe on his neck. TT!Mettaton gags and gasps for air. He falls down. As he fell, he took his shot and broke a window. TT!Mettaton's SOUL turns normal before he passes out.

"You okay?" TT!Nick asks. He causally walks over to TT!Kathy.

"No. What took you so long? I just saw what my life would have been with Mettaton flash before my eyes. It wasn't pretty." TT!Kathy answers as she regains her composure. TT!Nick offers his hand to help her off the floor.

"Life with a handsome robot would seem like a good life to most people." TT!Nick teases her. TT!Kathy is pulled up.

"Ha. Ha. Ha. Very funny Nick." TT!Kathy said sarcastically. She removes any dust on her.

"I told Gaster you had this under control. What do you want to do now?" TT!Nick asks her.

TT!Kathy walks towards the room that has the barrier with TT!Nick following her. They leave an unconscious TT!Mettaton behind.

"When I was with Sans and Frisk, they told me about a barrier in this place. It supposedly needs a human and monster SOUL in order to cross it. But, knowing a particular person... I think it won't matter." TT!Kathy informs TT!Nick. She just hoped that she remembered the details correctly.

"Oh. Let's go break a barrier then." TT!Nick said sounding like a kid.

The Author breaks the barrier because the plot demands it. The monsters reach the surface upon hearing word of the barrier being broken.

The king and queen went over to TT!Kathy and TT!Nick once the monsters set up camp. The king has broad shoulders, a golden mane and beard, a pair of visible fangs, a left large curved horn, a right broken horn, two medium length ears, and green eyes. This anthropomorphic king wears a suit of armor, a light blue cape with a dark blue trim, black with a yellow trim shoulder pads, and a yellow crown with a light blue gem. The king is holding a long, dark blue trident adorned with a light blue diamond.

The queen has medium length ears and medium length horns. She has a pair of visible fangs, long eyelashes, and red eyes. This anthropomorphic queen has a golden crown with three magenta gems. She wears a long dark purple robe with gray sleeves that displays this AU's symbol on her chest.

"I want to thank you two on behalf of the entire kingdom for saving us" TT!Asgore said with gratitude.

"I can't believe we get to see the surface again." TT!Toriel said with a disbelief tone.

"We can find the humans' families. They would be so pleased to see their children again." TT!Asgore said with a smile.

"What did you do to them?" TT!Kathy asks the royal goats.

"Human. We placed the others before you in cryogenic chambers. They have been asleep for all these years. We were about to unfreeze them, when Gem EX attacked us. I hope the chambers are still in the same place. My how two months just fly by." TT!Torial replies.

"Your majesties? Umm... It has been a year." TT!Nick said rather hesitant.

"How do you know that?" TT!Kathy quickly asks him.

"About a year ago, there was news that monsters had surfaced up. Paul and I went to go investigate. We found a small town, but no monsters." TT!Nick explains sounding rather disappointed.

He wanted to greet the monsters that day. The king and queen both knew. They called for TT!Frisk.

"How many times?" TT!Asgore asks sounding rather furious.

"I don't know what you are talking about." TT!Frisk said innocently.

"Frisk." TT!Torial softly glares at him.

"3... million." TT!Frisk said very quietly.

"Louder." TT!Asgore demands.

"3 million" TT!Frisk repeats himself. He fidgets in his spot.

"(Sigh) Frisk... I don't understand why you would do such a thing. How many times did we reach the surface? How many times did we die in the genocide route? How many times did we try to put you in the cryogenic chambers to prevent Chara from possessing you?" The queen asks.

"I... I don't know." TT!Frisk said honestly.

"Temmie? What is going on?" TT!Kathy whispers to her upon seeing the adorable creature.

She was passing by with a recovered rectangle Mettaton. TT!Nick simply listens to them.

"The Resets." TT!Temmie said in a hushed tone.

The king and queen take TT!Fisk to their tent.

"Resets?" TT!Kathy asks giving her a confused look.

"Frisk has the ability to Reset, darling. He has been doing that ever since he fell down." TT!Mettaton explains.

"That is... awful. I can't imagine living the same day over and over again. Is he going to Reset again?" TT!Kathy asks sounding worried.

"I don't think so. Ever since you fell down, Frisk hasn't been able to Reset." TT!Sans said as he joins the conversation.

"You don't think that..." TT!Kathy's voice trails off as she slowly put the pieces together.

"Darling? You okay?" TT!Mettaton asks her.

"No. If Frisk abused the power, then why me?" TT!Kathy slowly panicks.

"Probably because your Determination is stronger than Frisk's. I thought I would never see this day. Don't worry Kat. I may have known you for a bit, but I know you aren't gonna Reset a bunch like Frisk there." TT!Sans said hoping to calm TT!Kathy down.

TT!Kathy is surprised that TT!Sans calls her that. Only her friends call her Kat.

"I feel the weight of the world on my shoulders." TT!Kathy said quietly. She did not think the monsters heard her.

"If you ever think about Resetting, then call me. Maybe we can even talk about books. Lately, I'm reading a book about anti-gravity. It's impossible to put down." TT!Sans said as he pats Kathy gently on the back.

"I'll need your number first." TT!Kathy said with a small smile. She took out the phone and punchs in TT!Sans' number.

The pun went unnoticed by only TT!Kathy. After a good laugh, TT!Mettaton begs TT!Kathy to put his in. TT!Kathy gave in to stop his begging. She even added TT!Temmie's number. Apparently, TT!Frisk is grounded for life for abusing his power.

"Nick!" a familiar voice yell from the distance.

It is ArcadeJana and ArcadeSans. They rush over to TT!Nick.

"Hide me!" TT!Nick finally spoke. He quickly hide behind TT!Kathy. It fails because he is still visible.

"We have been looking all over for you. We need to talk." ArcadeJena said. She sounds out of breath.

"I know nothing." TT!Nick said sounding innocent. He uses TT!Kathy as a human shield.

"Stop hiding behind your girlfriend and be a man! Tell us how you know those names!" ArcadeSans said angrily. His eye glows blue and yellow.

"Your eye is on fire." TT!Kathy bluntly said. She fails to realize what ArcadeSans called her.

"I am not a man. I am a mouse. Tell them Kathy." TT!Nick begs.

"Kathy?" ArcadeJena asks as she looks at the human shield.

"Yes, I am she. What do you want?" TT!Kathy responds. She is confused because she had no idea what is going on.

"Your boyfriend here has very sensitive information that we need to know where he got it." ArcadeSans said aggressively. His glowing eye went away.

"Boyfriend? What? Listen here you two. Nick gets all of his information from Google." TT!Kathy lies as she gets a bit flustered.

She and TT!Nick are only friends. Besides, telling them that TT!Nick can read minds will make them hostile.

"Google? You mean to tell me that he gets his information from the internet!?" ArcadeJena sounds shocked.

"Yes I do. And I am not ashamed to say that." TT!Nick said as he came out from his hiding spot.

"So... we just came here for nothing." ArcadeSans sounded defeated. No one answers him.

"Just who are you?" TT!Kathy asks them.

"Kat. Do you remember when I told you that Gaster and I went to an alternate universe? These guys are from there." TT!Nick explains briefly.

"I'm Jena and this is my significant other, Sans. We are from an alternative universe called ArcadeTale." ArcadeJena introduces herself and ArcadeSans.

"Okay?" TT!Kathy said sounding very intrigued.

She didn't believe TT!Nick and TT!Gaster actually went to an different universe. But, seeing people that look very different yes similar from this ones here... clearly makes her feel like there is more out there. Perhaps there is a Kathy out there that is nothing like her.

There is a loud boom in the distance. It shakes the earth.

"What is that?" TT!Kathy jumps a bit from the loud noise.

"We should go check it out." ArcadeJena said. She led ArcadeSans towards the source.

"We should follow them darling." TT!Mettaton takes TT!Kathy's right hand and follows them.

"Hey!" TT!Kathy objects, but is not heard.

TT!Mettaton pulls TT!Kathy until they made it to the source. The leave the others behind.

Two figures appeared from the dust. The first has long black hair and bangs, ruffled black fox-like ears, a black coat with red stripes, a pale pink skirt, and orange eyes. ArcadeDescorda is her name. The other figure stands near her.

ArcadeLuminous is her sister. She has a white hoodie, white hair, gray eyes, an indigo shirt, white pants, and white shoes. Her sweater has white sleeves, periwinkle sides, and a royal blue belt near the top.

"Where is that rock?" ArcadeLuminous angrily destroys another building.

"If we don't find it, we won't get our utopia world." ArcadeDescorda sounded a tad stressed.

"You two!" ArcadeJena yell catches their attention.

She did not seem too happy to see these two sisters.

"Well. Well. Well. If it isn't the heroine Jena and her sidekick Sans. Didn't think you would find us here." ArcadeDescorda said with a wicked smile.

"After what you did last time, we can't let you go easily." ArcadeSans said with his eye glowing.

"Mettaton, stop pulling me!" TT!Kathy begs quietly.

She and the rest of the group are standing behind ArcadeJena and ArcadeSans.

"I sense the AU map that will lead us to the rock." ArcadeLuminous said looking around. Her eyes landed on TT!Kathy.

"Don't worry darling! I will protect you from these outsiders." TT!Mettaton said bravely. He pushes TT!Kathy behind him.

"I am not your darling." TT!Kathy hissed at him.

"How cute. Do you really think you can protect her from us?" ArcadeLuminous said with a sneer.

She suddenly rushes towards TT!Mettaton ready to fight him. TT!Kathy does not think twice. She uses her Eevee's Protect on the group.

ArcadeLuminous bounces off the green barrier. Her, TT!Kathy, and TT!Mettaton are sent into a battle.

(Enemy Approaching [ArcadeTale ver.] plays)

ArcadeLuminous stood across from her opponents.

"Are you going to spare me, Frisk? You should know that won't work." ArcadeLuminous said angrily.

Knowing that ArcadeFrisk is friends with both sisters, ArcadeLuminous is actually expecting this Frisk to show her mercy.

"I am not Frisk." TT!Kathy said as she chose the "Fight" button. TT!Kathy uses Swift on ArcadeLuminous.

"What?" ArcadeLuminous sounded surprised. She barely dodges the attack.

TT!Mettaton launches a few yellow bombs. They exploded when it hit ArcadeLuminous. She did her best at dodging, but the bombs took off 50 HP.

"I will kill you both then!" ArcadeLuminous said enraged.

She would have to kill them unless they show Mercy. She attacks both TT!Kathy and TT!Mettaton. TT!Mettaton got hit, while TT!Kathy dodges the attack. TT!Mettaton lost 20 HP.

TT!Kathy chose to "Fight". This time, she uses Hidden Power. ArcadeLuminous is unable to dodge. TT!Mettaton launched the bombs again. None misses. Max damage!

ArcadeLuminous is too tired to attack. TT!Kathy uses the "Fight" button yet again. She uses Swift. Critical hit!

"Maybe we should Spare her now." TT!Mettaton suggested as he choose not to attack.

ArcadeLuminous is low on health. ArcadeDescorda enters the battle. She sees her injured sister.

"You are not like the other Frisks that we have met." ArcadeDescorda points out. She sounds impressed.

The sisters are sparing you.

'Giving up already? I never seen this before. Most people I have met would have fought until the very end.' TT!Kathy thought.

TT!Kathy chose the "Mercy" button after curiosity got the better of her.
TT!Mettaton did the same.

The song ends as does the battle.

"So, 'not' Frisk, what are you gonna do now?" ArcadeDescorda asks as she helps her sister stand.

"I want to know what you two are doing to this town." TT!Kathy sounds hostile.

"We are looking for something called an AU rock. Now if you can kindly tell me where it is, we won't destroy this entire village." ArcadeDescorda answers in a threatening tone. ArcadeLuminous groans in pain.

"My head. Ugh! Descorda, we have to retreat to our home world ." ArcadeLuminous said as she rubs her head.

ArcadeDescorda glares at TT!Kathy before using an AU portal remote. The thing is gray and has a small screen that lists the AU the two sisters are going to. ArcadeDescorda typed in "ArcadeTale" before pushing a red button.

A slate colored swirling portal appeared. ArcadeLuminous swiftly dragged TT!Kathy in.

"Darling!" TT!Mettaton cries. He runs to the portal.

ArcadeSans and ArcadeJena could not believe what had occurred. They are so baffled, that they do nothing.

"You won't stop us this time!" ArcadeDescorda said with a sneer.

ArcadeSans and ArcadeJena went through the portal. TT!Mettaton could not rescue TT!Kathy.

"We should follow them... right?" ArcadeJena asks ArcadeSans.

"Yeah... We also should have stopped the battle." ArcadeSans looked lazily at the ground.

"Don't we have some kind of remote to follow them?" TT!Mettaton asks the two.

"Yeah... ArcadeGaster gave us an AU portal device a long time ago. We can use it to get to ArcadeTale." ArcadeJena brings out the remote.

- ArcadeTale: Waterfall Area -

"I can't believe this. Even after Frisk befriend them." ArcadeSans sighed heavily as he went through the portal. He waited for the others.

"Who are those humans?" TT!Mettaton asks.

"Their names are Luminous and Descorda. They are from our AU. And they are a bit dangerous." ArcadeJena said. She does not want to tell a stranger the whole story.

The sisters have not bothered them since ArcadeFrisk befriend them. So why are they trying to steal the AU rocks? ArcadeJena ponders this as the portal closes behind her.

"What is an AU rock?" TT!Nick asks snapping ArcadeJena from her thoughts.

"It's hard to explain." ArcadeJena said trying to think of the best way to explain it.

"All we know is that our universe has a rock that keeps the world going. Kinda like water." ArcadeSans did his best to explain.

"Okay? So... without the AU rock the world stops?" TT!'Mettaton tries to understand.

"As far as we know yes. The world eventually dies." ArcadeSans said before he realizes that there are four of them here.

"Wait... How the h-ll did you get her?" ArcadeJena beats ArcadeSans to the punch. She sounds unfriendly.

"I teleported at the very last second." TT!Nick rolled his eyes.

"... I... I am speechless." ArcadeJena said with a sigh.

The group begins to search for the lost cat. So far, TT!Kathy and the two sisters are nowhere to be seen.

Meanwhile, in a different part of Waterfall. The two evil sisters are dragging TT!Kathy. TT!Kathy's hands are tied with a rope that the sisters found. They carefully watch her as they whisper to one another.

"Why did you tell us to retreat? We could have beaten them if you did not fall asleep." ArcadeDescorda scolds her sister.

"Hush now! I sensed the rock when that girl showed up. I think she is the key to finding the rock." ArcadeLuminous said in a hushed tone.

"She must be like Ahri then. The two must be the maps to finding the their AU's rocks." ArcadeDescorda said putting two and two together.

"Yes. And since she doesn't know us, we can get her to lead us to any AU rock." ArcadeLuminous said with a smile.

"For our sake, I hope she can find all the rocks we are looking for." ArcadeDescorda said in a strict tone.

"Lets go find them." ArcadeLuminous said.

TT!Kathy heard every word. They are passing by some glowing blue flowers. They are releasing some blue pixels. They are called Echo flowers. How does she know that!

"I think you should know that I am not Frisk. My name is Kathy. And I would like to be freed from the rope." TT!Kathy said nicely. Both sisters looked at her.

"Kathy? As in Ahri's good friend? The one whom is supposed to be in the hospital?" ArcadeDescorda asks as she is caught off-guard by TT!Kathy's niceness.

"This is not our Kathy, sister! She is from another universe." ArcadeLuminous scolds her sister.

Both began to bicker over this. TT!Kathy sees her chance. She quickly unties the poorly made knot by pulling it with her teeth. TT!Kathy then uses Eevee's Dig to get far away from the sisters.
