CHAPTER 1: The World Of Pokémon

When Frisk used the reset button, but there was a glitch and instead of resetting everything over like normal. Everything was reset to something and somewhere new and different.

Sans, Papyrus, and the other Monsters however were brought along too. Frisk wasn't sure what was going on or even where they were, but it seemed familiar to Frisk.

Until she and the others found a abandoned Mansion that was huge and had enough room for every single one of them. However when they entered they found some kind of ghost like monster already living there, that looked very familiar to Frisk. So Frisk and Sans went up to it to speak to it.

But they were put into battle with the said Monster. However the Mercy button was gone and was replaced with a Catch button and a Run button.

This confused and worried Sans, but to Frisk it was familiar to her. She tried to remember, but it was useless. Sans looked at the Monster and asked it a question…

"Hey friend? We don't know what's going on and where the heck we are. Can you please help us?" Sans asked, the Monster look at him shocked.

"You can speak Pokémon?" It asked, everyone looked in confusion except Frisk.

Who look up in shock, disbelief, and became extremely excited. So much so that a huge smile appeared on her face. She was vibrating with happiness.

Frisk's POV

"Wait Pokémon!? No wonder everything here looked so familiar to me!" I exclaimed, Everyone looked at me in shock.

Cuz I usually have a blank and emotionless face which normally showed little to no emotions. Changed for the first time since they met me. Their expressions soon turned to questioning looks.

"Umm… Excuse me my child, but what's Pokémon?" Queen Toriel/Mom asked, everyone looked at me as I started to speak.

"Pokémon was a video game series that I had used to play back in the over world. I was basically a huge fan girl of it, but… after I fell into the Underground and you found me in that flower bed. I haven't played since and all the resets didn't help. I basically became immortal. I never even aged. I've made a log of everything with the amount of time I've been in the Underground. If I had never fell I'd be in my earlier or late thirties." I said, she looked at me in shock.

I tried bringing out the reset button, but instead a save button and some save slots appeared. I then began to panic.

"Kid what's wrong!?" Sans asked, seeing that I was panicking he pull me into a hug.

"Calm down Kid. Your scaring me. Tell me what's wrong." Sans asked, me softly. I closed my eyes and focused on my breathing.

"T… th… the… the reset button is gone, Sans!? What are we going to do. What will happen if Claire takes over again!? I don't want to kill you guys again!?" I said, while crying Sans continued to hug me.

"Kid you don't have to worry about that bad bone anymore. I looked into your soul and found that Claire's influence and spirit are gone your free. That's not all I also found out that me and the others' body's physiologically changed to match with this world in some way or something. I've lost most of my bone breaking speed, but in exchange my health increased and we bon't have to worry about becoming dust anymore." Sans said, I looked at him with hope.

"Really? You aren't lying, right?" I asked with tears falling. He wiped away my tears and gave me a kiss on my forehead making me blushed slightly.

[A/N: Frisk was 18 when she fell into the Underground, but because of how much time she had been down there and trying to help free the monsters and resetting every time she remained the same age, but time still moved the same. She been there for about 25 years. She fell into the Underground in early 2021. I know Undertales has been around a lot longer, but this is my first time making a Undertales fanfiction and I never played the game I've only seen a few animations on YouTube. So I'm sorry if I don't get some of the characters names and their personalities' right. I hope you all understand.]

"Yes, I'm sure Kid. You have nothing to worry about. I assure you." Sans said, rubbing my back calmingly it took a while but I was soon calmed down enough to talk again.

"Can you tell us more about this world? It may help us with understanding it better." Mom said, everyone nodded and looked at me.

I smiled and took a deep breath and started explaining everything.

"Sure, basically this world has Monsters that are called Pokémon. Pokémon are creatures that you can catch, train, battle, evolve, play, and preform with. In the pokémon games I've played and I for some reason liked pokémon that had looked scary and creepy to most people, but I found them cute.

There are 18 Pokémon types. Normal, Fire, Water, Grass, Electric, Ice, Fighting, Poison, Ground, Flying, Psychic, Bug, Rock, Ghost, Dragon, Dark, Steel, and Fairy.

Each type has its own strengths, weaknesses, and immunities. Ghost types for example are both strong and weak against other Ghost types. They are also weak against Dark types. They are strong against Psychic types. Poison type attacks aren't very effective against them. They are immune to Normal type attacks and Fighting type attacks and Normal types are immune to Ghost type attacks.

But a Pokémon can have up to two different typeings. Like Gengar here. Gengar is both a Ghost and Poison type Pokémon.

Gengar is also one of my favorite pokémon along with Mimikyu, Shiny Phantump, Shiny Hisuian Zorua, Darkrai, Alolan Marowak, most of the starters Pokémon, and Arceus's Mega Ghost type form." I said, taking a breath.

"Can we kill them?" Sans asked, I looked at him in shock.

"What!? No! Don't you even try to either! And why would you ask such a question Sans?! Also I think you guys should stay hidden here while I go to get some stuff to help hide your Monster appearances. I don't want someone to accidentally think you're a new species of pokémon and try to catch you. Sans you can come, but keep your hood up and head down. I suggest you change your shorts and slippers too. So you can hide the fact you're a living skeleton better. We can go and try selling the ruby currency from the Underground for Pokédollars." I said, handing Sans a pair of jeans and a pair of shoes.

He took them and put them on. We said our goodbyes to everyone and started towards east-west. After about 30 minutes of walking we had made it to a town. We entered a Pokémart. I went to the counter with Sans following.

"Excuse me?" I said, gaining one of the staff's attention.

"Yes?" He asked, looking at me.

"Can you tell me how much each of these are?" I asked, putting a green, a blue, a red, a purple, a silver, a gold, and a white ruby onto the counter.

This gain the staff's full attention. He looks at each of them very carefully to make sure they were not fake. He looked at me and Sans for a moment before answering.

"The red, green, and blue gems are worth about 25,000 each. The purple gem is worth around 50,000 . The silver one is worth 500,000 . The gold one is worth 1,000,000 and the white one is worth about 100,000,000 ." He whispered the last three to us.

He looked at me and Sans suspiciously. I looked at him with sadness.

"Kid where did you even get these from?" He asked, I smiled.

"The Underground! I was going around a cave smashing rocks when I suddenly found them after I smashed a rock and they among a lot of others." I said, this was not a complete lie or the truth either.

"Hmmm… I guess I'll take your word for it Kid, I'm Jeffrey by the way. Also I suggest you keep the prices of these three a secret to strangers. But if you want to sell them I recommend you sell them to only me and my brothers. So how much are you wanting to sell?" Jeffrey asked, with a smile.

I nodded and smiled. Jeffrey continued to smile. He rang up the money. It was a total of 101,625,000 , but I gave him more to round it up to 15,000,000,000,000 .

I decided to buy, a lot of Pokéballs, Great Balls, Ultra Balls, and everything else a pokémon trainer would need. We then said goodbye to Jeffrey. We then went to get some stuff to help hide our friends appearances. Clothes, shoes, hats, and bags.

Monsters who have tails either wear a dress, skirt, or Robes. Horns depending on how big they are. They will have to where a hat or a hoodie to cover their horns. They should be quite comfortable with and in their new disguises.

"Thank Arceus that I still have access to my unlimited pocket space storage. We be in trouble if I didn't still have it." I said, when we finally returned.

"I'm bone tired, kid. I'm going to go catch some Z's." Sans said, as he was lead by a Hunter and a Shiny Umbreon to his room I yawned and decided to followed them with Sans.

When we finally made it to the room. I thanked Hunter and Umbreon for the help and gave hunter two big boxes that are full of poké food, berries, Poképuffs, Pokécandies, and other foods that are for specific Pokémon.

"Here I'm not sure if it's enough cuz I don't know how many of you live here before me and my friends came so I hope you enjoy it and please share if it isn't enough I'll leave more beside our room door. Okay." I said with a smile.

"Hunt hunter!" Hunter said, then smiled.

"He said that it should be more than enough for everyone and also thank you for the food." S. Umbreon spoke Telepathically, and he then bow his head.

I smiled and scratched him behind the ear and offered him a Halloween theme Poképuff he quickly ate it and I cleaned off the crumbs off his face and he looked at me with a happy look. Before he ran off.

I entered the room and cuddle up against Sans under the covers. He hugged me closely. I smiled and snuggled into his chest and quickly fell asleep.

???'s POV

So I was successful in bringing them here. Good. I think I'll visit them tomorrow and introduce myself to them. Frisk knows a lot about pokémon and this world, but she, Sans, and Papyrus will have to leave and meet up with Ash, Pikachu, Serena, and Faye. So that they can help them save my world from Dieceanna (Die • C • Anna). Well I best start heading to them.

"Izuku!" I yelled out.

Suddenly a flash of green light appeared and in the shape of a green cat like pokémon.

"Yes, Lord Arceus?" Izuku asked, I smiled at him even though he may be a human with the ability to transform into any of my children. He's from another world that has super powers known as quirks.

He has a good heart and a good head on his shoulders. He still a hero in training, but he never ignores me when I call for him. I would go as far as to say I already consider him as a son.

"Izuku I'm trusting you to watch my pokémon worlds. While I make a trip to one of them to visit. I trust that you understand what I need you to do, correct?" I asked, he nodded and transformed into his Mega Arceus Form.

"Of course I do, Father." Izuku said, then he bowed his head and started watching my multiverse. I smiled at Izuku before transforming into my humanoid form.

And started speeding towards Frisk, Sans, Papyrus, and their friends.

"GOOD LUCK, FATHER!!" Izuku yelled after me.

"THANK YOU, MY BOY!" I yelled back.
