Author's Note: TT = TemTale

Season 1 Summary: Kathy and Nick are back! The two duo are sent to various Undertale AUs. The two must work with the other AUs to stop the villains Luminous and Descorda. The villains are stealing AU rocks. Can Kathy and the gang stop them before it is too late?


It has been two months since TT!Frisk fell down the hole. King TT!Asgore and ambassador TT!Frisk has been doing a good job at merging the monster kind with the humans. Many of them are like TT!Frisk, the rest are shy or scared around the monsters. But soon, they too turn kind like TT!Frisk. Some monsters are unable to go above the ground. TT!Frisk has deemed them too "different".

TT!Temmie is a monster that met the criteria. All she ever wanted to do is to go to college. Despite her being deemed too "different", TT!Temmie is persistent. She asked TT!Asgore why she could not go to the surface world. TT!Asgore would come up with an excuse for why she could not go above. TT!Temmie would nod and come back the next day. She did this for one hundred days straight. On the one hundredth day, TT!Asgore got angry at her. He told her why she could not go above.

"Don't you understand? You are too different. That is why you will never go up there!" the king roars with anger.

The words echoed in the castle. TT!Temmie begins to cry.

"B-but.." she begins but her tears stop her from talking.

The king setting aside his anger told her to go home. TT!Temmie did not listen. She ran to the door that stood between her and the surface world. The king ran after her.

Outside, TT!Alphys and TT!Gaster were doing an experiment right outside the door. It is meant to bring TT!Gaster back as a skeleton.

"Stop that monster!" the king yells as loudly as he could.

TT!Gaster stopped what he is doing to catch TT!Temmie. TT!Temmie is still crying when TT!Gaster scooped her up. TT!Alphys yelled at TT!Gaster to not move. She had pulled the lever. TT!Gaster and Temmie fused into one entity. They had become TT!Gem EX dubbed by TT!Alphys. TT!Frisk quickly received word of the new threat. Unable to befriend the monster, TT!Frisk sealed the creature by reinstating the barrier. Fueled with anger, TT!Gem EX rounded up all the monsters using their new powers. TT!Gem EX decided that if they could not go outside, then no one can. TT!Frisk went back to the hole and tried to Reset the place. But, it is too late. There was nothing anyone could have done to stop TT!Gem EX.

- One Year Later -

TT!Kathy and TT!Nick are climbing up Mount Ebbott. TT!Kathy has dark brown hair, brown eyes, a grey head-band, gray pants, glasses, soft red shirt with two white strips on the side, and white shoes. TT!Nick has blue hair with the front part slightly covering his eyes, blue eyes, white shirt with blue buttons, blue jeans, and white shoes.

The duo decided to take a vacation from their everyday crazy life. TT!Nick reached the top before TT!Kathy. He could have become a dragon and just have flown up the mountain. TT!Nick decided not to and scale this mountain without the use of flight. Then again, he could teleport.

"Next time, choose something smaller to climb." TT!Kathy said out of breath.

She has never climbed a mountain as tall as this one before. TT!Nick pulled her up.

"Thanks." TT!Kathy said setting her backpack down.

"Would you look at that view." TT!Nick said in awe as he placed his backpack in his virtual inventory box (VI box for short).

As TT!Kathy looks at the view, TT!Nick's watches beeps. He decides to investigate this phenomenon. It leads Nick to a large hole on this mountain top.

"Nick, how high do you think we are?" TT!Kathy asks looking away from the beautiful view.

TT!Nick did not respond. He is staring down the hole. TT!Kathy walks over to him to get his attention. She then saw this adorable strange creature. It barely climbed out of the hole. The fluffy creature is directly across from the two humans.

"Aww! What a cute puppy!" TT!Kathy said practically falling in love with the creature.

TT!Nick stared at the creature. It is giving off strange readings on his watch. TT!Nick silenced his watch as the creature looks up at them.

"Hoi! I'm Temmie! Good to met u!" TT!Temmie chimes.

TT!Temmie resembled a cat with dog ears on the side of it's head. It has normal cat ears, shoulder length gray hair, a striped blue and black shirt. TT!Temmie sounds female. TT!Kathy's heart melted at the sight of TT!Temmie's cuteness.

"Did that dog just talk?" TT!Kathy asks in utter shock, yet still in love with this cute creature.

TT!Nick debated on whether or not to tell her where they are. Would TT!Kathy believe him if he told her that they are in Orville, Nevada? Or that they had only climbed for an hour because TT!Nick teleported them to a certain point of Mt. Ebbott? Or the fact that he hypnotized her to sleep, just to pull this all off? Probably not.

"I'm trwing to get to the surface. But Tem too scared to fall into ole and hurt myself." TT!Temmie said whinnying a bit.

"Aww! We will help you Temmie." TT!Kathy said talking to TT!Temmie as if she was a baby.

TT!Kathy wanted to hug TT!Temmie. TT!Temmie wags her long white tail. TT!Temmie is happy that someone is finally going to help her.

TT!Nick notices a white hand with a hole in the middle. The hand drags that monster dog down. To TT!Kathy, TT!Temmie fell into the hole without warning.

"Temmie!" TT!Kathy yells.

Without thinking, she jumps after the dog.

"Kathy!" TT!Nick yells. TT!Nick wanted to go after her, but he lacks the emotions to do so.

'Interesting... When is the last time that was written? Being soulless down there may be bad for me, if the monsters find out.' TT!Nick thinks as he debated on jumping in.

Unable to feel, TT!Nick goes after her.

TT!Kathy is falling faster than him. She had somehow managed to grab to TT!Temmie. TT!Kathy and TT!Temmie appeare to be unconscious as well.

'The shock of the fall must have sent them into shock.' TT!Nick thinks as he grew out his dragon wings and tail.

His gray wings propels him forwards. His tail kept him from spiraling out of control. TT!Nick reaches TT!Kathy holding on to TT!Temmie in the matter of seconds. He now has them in his arms. TT!Nick is about to fly back up when he spots a ghost.

It is appears to be a skeleton monster. It has a black coat, grey pants, black shoes, a bright blue shirt, and white hands with a hole in the center. The monster's face had two chunks missing from the top left an bottom right and his eyes sockets were a rectangular shape with white pupils.

TT!Nick knew that this monster caused TT!Temmie to fall once he recognized the hands. TT!Nick used his tail and wings to keep the creature away from the duo. TT!Nick wanted to get out of the underground. The creature's pleading look gave TT!Nick a sense that this creature needs help. TT!Nick then noticed a bright yellow dog collar that is around the creature's neck

TT!Nick could not explain why this monster wanted his help. They did just meet. The ghost then flew towards TT!Nick. That caused TT!Nick to panic. TT!Nick dropped TT!Kathy and TT!Temmie in an effort to keep the ghost from going inside their body. It is too late. The ghost went inside of TT!Nick. TT!Nick teleported out of the hole from panicking.

- ArcadeTale -

Meanwhile, ArcadeAhri Foxtails is talking to ArcadeJena and ArcadeSans. ArcadeAhri is one of the goddess of her AU and the Author of ArcadeTale. Though no one knows that she is the Author.

She has long beautiful white hair, blue eyes, and a single white tail. Her outfits consists of a white shirt with a blue crystal in the center, a white skirt, yellow boots with a blue crystal in the center, a yellow crown with a blue crystal in the center, white wings with a blue protection on the top part of the wings.

ArcadeJena is listening to her. Her outfit consists of a purple with pink in the middle coat, blue jeans, white shoes, a pink sport headband, yellow eyes, and light color brunette hair. Under ArcadeJena's bang, there was a small "bandage". It is in the shape of a diamond and is purple with a pink outline.

ArcadeSans is half-way listening. ArcadeSans has a bright blue sweater, blue shorts with purple diamonds, blue sneakers with a bit of yellow, blue headphones that are attached to yellow glasses, and a yellow scar on his left eye. Some call him Arcade for short. He knows that they are talking about going to an AU to protect something called the AU rock. Apparently these rocks may be in danger. ArcadeSans thinks to himself that they are overreacting.

As the trio are talking, the sky from above opened up. TT!Nick and the ghost fell through the hole. TT!Nick has reverted back to his human form. ArcadeSans quickly jumped into action. ArcadeSans uses his telekinesis to slow TT!Nick's and the ghost's fall.

ArcadeAhri and company ran to where ArcadeSans lowered them to. Upon arriving, they saw what seemed to be a younger version of an AU Gaster. They have never seen a Gaster like this one before.

"Are you okay?" TT!Gaster asks TT!Nick as he pushed himself off of TT!Nick.

He sounds scared.

"Nah... What? Where?" TT!Nick slowly gets up.

He rubbed his head. TT!Nick felt drained. He looked around the place that he is in. Did he and that ghost went into a different AU when the ghost went inside of TT!Nick? That is interesting. Slowly recovering, TT!Nick stretched like a cat.

"Hey! You okay?" ArcadeSans yells getting the duo's attention.

The trio stopped running upon seeing both the man and ghost completely unscathed.

"Yeah... we are fine." TT!Nick said with a smile.

TT!Nick began to read the minds of the people around him once he regained some of his strength. That should allow TT!Nick to act in a specific way.

"I'm so sorry! I thought you were a superhero. And you are one! This is the best day ever! I need your help." TT!Gaster said enthusiastically. The ghost seems to be blissfully unaware of their situation.

"I don't know what you mean by that, sir. I am just a normal man who was teleported to this place by you." TT!Nick said in a calm tone.
