||||| This is a concept I have for my Undertale/ Pokémon crossover |||||

The strings that upheld them forced Frisk to follow the strange Umbreon. They liked him. Though the face honestly spooked Frisk, they were forced to oblige to the wishes of the entity controlling them, however. They didn't a choice in this.

Frisk sighed as their body moved wobbly, but the entity didn't seem to care about taking their time like the young human child did. It was unnatural, this entity. It seemed to want to help, but it also took them down a dangerous path.

Frisk shivered. They didn't want to relive it. Seeing their friends fall in the run they were on was more than enough.

No control. Frisk wasn't in control.

Fear. One day, the entity would get bored of this run again, and take everyone out.

Frisk shook their thoughts as an invisible controller forced them to move around a tree. Now wasn't the time. They needed to get out of here and save their friends by leading them back to their world.

The Umbreon, Eon, glanced back at them with a slight smirk. "Well, we're here." He informed them with aloofness. His scarf suspiciously staying still when the wind blew.

"Can't believe that worked. I'm glad I got you right where I want you. You're very stupid, you know? Following a stranger. Haven't your parents ever told you not to trust strangers? Hah! This is the perfect opportunity to defeat you." The Umbreon commented, shooting a Shadow Ball at Frisk.

Frisk yelped, unaware of the situation. What was going on?! They were tricked?

The Umbreon continued.

"Didn't you know the ruleset for this world? Heh. Liar. You're from this world, aren't you? You just wanted to mess with me."

"In this world, it's Battle or be wreaked." The Umbreon started firing off a brigade of Shadow Balls.

Frisk managed to dodge the Shadow Ball. The entity must have known this trick beforehand. It was used with Flowey after all. Was this Flowey? Or was this some bad Pokemon?

Frisk could feel something in their soul tell them no. This Pokemon—or whatever the creature was if they were lying about this being some sort of Pokemon world—was obviously not evil; they were struggling. Frisk didn't know with what exactly, but they could see despite the harsh exterior their eyes shown regret.

It was as if they didn't want to do this; the regret didn't stop them from firing attacks, however.

Their attacks hit Frisk after a bit of dodging. It seems the entity in control couldn't dodge the attacks forever. 

I don't even know how I am doing this. Frisk thought as they panted heavily from the dodge attempts.

The young Cyndaquil barely jumped out of the way of an incoming black-and-white attack. The Umbreon turned around in anger.

"Stay still?! It'll be easier for the both of us if you just give up." These words. Such familiar, yet still unique. Frisk felt angry. Give up? Is there such a thing as giving up?!

This Pokémon was the one who attacked them, and he would be the one to regret his decisions. Frisk tried to use an attack move; they failed to even begin to charge up the Ember attack.

Dang it! Eon—this villain makes it look so easy! But I'm not a Pokémon. I'm a kid.

Frisk sighed. How could they even beat this creature if they puke to even charge up the ember? Or whatever that fire attack was. Frisk wasn't even sure if this Pokémon had been lying to them about the rest. Their identity, however, didn't seem like the Umbreon called Eon they were meant to pretend to be.

Frisk shook their head. They couldn't give up now! The strange entity behind them wouldn't, and neither shall they. The entity was silent, but right in one way: they had to fight. And fight they shall. Frisk flinched.

But not kill. They did not wish to kill. But was it really up to them?

Frisk could feel their soul resonating, allowing them control. For now. This battle has allowed both of them a chance to attack this unknown creature, this such unknown Pokémon.

This soul of theirs—it wanted revenge. Despite it holding itself back, this entity within their soul really wanted to hurt this creature. It wanted to harm this creature for lying, for deceiving them and their friends; it wanted revenge for attacking Frisk and leading them away from all their loyal friends.

How would their friends react if they found Frisk dead? The soul seemed to be asking such questions as it took control out of rage. This greatly scared Frisk. What if the controller wanted to kill again?! Frisk wouldn't be able to stop them.

Their eyes widened, and the entity seemed to understand they were overstepping the child's boundaries. The entity let Frisk take control, carefully glowing inside their chest.

Fortunately for Frisk, the duplicate Pokémon in front of them didn't question the strange struggle; they only seemed to stare at Frisk for a moment before continuing attacking. However, their expression seemed disturbed.

Frisk fought off the creature with as much attack as they could, begging the entity to use the powers since they themselves didn't know how to, and the entity seemed to know how to use the powers they had more.

Fire powers. Fire moves. That's what Eon, or whatever this Umbreon's name is, claimed what Frisk had was. But should Frisk use those powers? They felt...like too much.

Frisk pondered it for a moment. I've used violence before, but that was with my own two hands. And now? I've got superpowers I can use to defeat others. Is this really a good thing? Sure it's easier, but at what cost are these powers given to me? It frightens me. Frisk thought as they skid to a halt in front of the Umbreon.

They weren't moving themselves this time.

The cost? The cost of these powers? What more could these powers be used for, but for battle? The creatures here faint and fall over, not die. As long as you hold back everything you have it'll be okay. I promise you with each control I do, I won't cause chaos. Not this time, little Frisk. There's definitely something bigger at stake here than what either of us can imagine. I'll help you with these fire powers for now, but the Ember must at some point come from your own skills.

Frisk opened their mouth as they felt something warm build up within their chest. Then that fire formed in their mouth and they shot the ball of fire, charring not only the Umbreon, but the area around them.

Then, the Umbreon fainted and changed shape. It was a purple gooey creature. Frisk growled. So they weren't even an Umbreon? Before Frisk could take things into their own paws, a bone shot out from the ground. The strange purple blobbing Pokémon screamed, and just barely dodged the attack in their weakened state. Unfortunately for them, a Cubone with psychic powers grabbed a hold of them with those same powers and held them down with blue energy.

"Who are you, and why are you attacking Frisk?" Sans growled as one of his eyes glowed blue. Frisk could see all their friends show up, prepared to attack this strange blob in case they tried anything and were able to escape the blue magic.

The purple creature just panicked. The one thing that stayed the same between transformation was the weird face, which seemed to fit the purple blob better than the Umbreon they claimed to be. "P-Please don't hurt me!" They stuttered in fear, their blobby body shaking immediately. The strange bubbly creature was now acting like a victim instead of acting like the one who attacked first.

"Then, talk. Why'd you hurt the punk?!" Undyne shouted, her eye glowing through her patch with rage as she threw her bigger fish paws towards the abomination. The purple creature screamed in pain, profusely apologizing. Tears began to stream down the strange creature's face.

They were a medium purple, with narrow brown-black eyes. They seemed to not have any paws or feet, molding them from whatever body they had. They were surely a weird creature, that's for sure. Nothing like Frisk had seen on their journeys.

"I-I," the purple creature began shaking violently. "Undyne! You're scaring them! They can't tell us anything if you're going to strangle them! Let them go." A soft voice soothingly brays.

Frisk smiles at the voice of their goat mom, now bearing huge horns and a strong appearing grassy body. Frisk wouldn't want to mess with her, they knew that. They've experienced it before and hated it. Many times actually.

But seeing her here to protect them— it was nice. Undyne dropped the Pokémon. The Pokémon was still shaking. "T-Thank you! I'm sorry, I really am! You all seemed so nice, so I thought I'd take advantage of your niceness. I just...thought if I could defeat an opponent for once, the starter squad would let me in—you wouldn't even know, though. I saw that delayed Ember coming from your Cyndaquil friend. I didn't believe you when you said you weren't from this world and now—it's a weird thought, but it makes more sense now."

The Pokémon moved a bit before continuing, shaking. "I didn't lie to you when I defined Pokémon, however I lied still. I lied about being an Umbreon—being Eon. I am not an Umbreon, nor am I called Eon. I took that name, stole the appearance you saw, and started this whole thing to prove I'm worthy enough to be called 'powerful'. I'm sorry, this world is a cruel one. It's made everyone's heads a little insane." The purple creature spoke before bowing a little; their figure squishing flat like a pancake.

Why would you want to become powerful? Is it because of this 'Starter Squad?' They sound like a super secret club or something. Frisk thought warily. They dared not say this out loud.

This Pokémon seemed sensitive—maybe false but even so, Frisk wanted to help them if it would be useful to help them prove themselves to someone who thought they weren't worthy. Frisk knew what that was like. Their energy was beginning to return to them, their strings loosening.

At first nobody said anything, but then: "THEN WHAT ARE YOU CALLED, WEIRD PURPLE BLOB? THE GREAT PAPYRUS WOULD LIKE TO KNOW WHAT AND WHO YOU ARE." Papyrus 'stated.'

The purple Pokémon glanced at the ground at first, nervousness spiking as they sighed. "I'm considered an abomination to the other Pokémon." They began, closing their eyes in pain from the words spoken about them. "A failed clone of the Pokémon, Mew. The myth, the legend, the true new species Pokémon. I was one of the failed attempts. There are many like me. Eventually, the humans would make Mewtwo: the true clone of Mew. And me? I'm just a failure sent into the wild because this is my true form. I'm genderless—they and them to you, I can transform just like Mew, heck I can even use opponents moves like them. They didn't want me. No one wants me. I'm not worthy enough for anyone, aren't I? I just thought proving myself to the other Pokémon would make them realize how cool Ditto can be—that's what I am, a Ditto."

That didn't answer anyone's questions about who they were, but no one interrupted them. Frisk felt sorry for this 'Ditto.' Being shunned just because you're a failed clone of something sounds awful. Why was this Mew so worshipped by humans? Frisk didn't understand their own species—not in this universe at least. Even though their looks were odd, Frisk could tell they were a powerful Pokémon. They had more than took them on, though Frisk was unsure how they failed at beating them.

"I've been constantly trying to prove myself all my life. No one wants a Ditto like me in their life. 'Ew, Gross! A Ditto! Get it away from me!' Or, 'Ditto are the world's most undesirables for dating and friendship. Stuff like that. I'm sorry for attacking the child. I just wanted to show I was a Pokémon to be reckoned with." The ditto apologized.

"I forgive you!" Frisk cheerfully exclaimed without a second thought. The Ditto confusingly frowned. They didn't seem to understand why Frisk was so forgiving despite everything they've done against them. They forgave their friends when they attacked them. In fact, Frisk enjoyed the way they made them their friend. It was just in Frisk's nature to forgive. They might have forgiven their actual human parents way too many times before.

"Wh-what? I—Anyways my name is Puro. Puro the Ditto. I know I attacked you and everything, but I hope we can become friends." The Ditto introduced himself. "That's how it always happens with friendship!" Frisk cheerfully accepted, immediately hugging the Ditto like they've been friends longer than five seconds. "E-Excuse me?" Puro confusingly stuttered in alarm.

Sans was amused. "Oh man. You don't know how friendship really works. Don't worry, it's as easy as sleeping and eating all the ketchup." Sans assured lazily, putting a paw on the Ditto's head since he—more like no one—had no idea where their shoulders were.

"SANS! THAT IS NOT A VERY GOOD EXAMPLE!"

Sans snickered. "Well, you know what I mean, Kid."

Anyways this is the concept I have for that Undertale/Pokémon story. Not sure if this is going to be copy and pasted or if I'll edit it and then decide to put it in or what. All I know is I want to add this Ditto named Puro.

Yes Puro is named after the character Puro from the video game Changed. I thought the name was too good to not use it.

Anyways, I hope to see some thoughts on this. I don't really know if it's a good idea. I mean I like the idea of Ditto being shunned for being fake Mews. Also I thought the in this world part of Puro's philosophy was funny. Not sure if it's the best one I could have used for them. And yeah them is what I do plan on using for the gender because it just makes sense. Especially in a world where Pokémon who are genderless do give themselves gender labels despite being genderless/unidentifiable sexes.

Anyways let me know your thoughts. I put a lot of work into thinking of how to introduce Puro. Lol.
