This is just my AU based on pokemon Black and White. Some of its story is different from the game. (Also bad grammar)
Thousand years ago.
The illusion fox was rolling around in the snow in front of the cave, while his friends tried to make a snowman with their soft paw. Although that was the coldest winter the ghost/normal pokemon had ever felt, it is also the most memorable memory he had. 'Why?' people may ask...
Only a week after that winter, an event that affected to the whole Hisui happened. The two legendaries Dialga and Palkia were out of control.
Even though they had the chosen one who was sent by Arceus prevented the situation from being worse, a lot of pokemon living at Mt. Coronet included all the poor Zorua's friends couldn't make though it.
Everyone but him...
The wave of time which appeared when Dialga attacking suddenly hit the white fox, 'but nothing happened...' At least that's what he thought.
The illusion fox managed to run away from the chaos.
In the present, Unova region.
At Accumala town, while team Plasma is talking about 'Liberating pokemon from human' at the town's centre. N, who is the king of team Plasma, is standing in the corner of the town, observating people and their pokemon. Then a brown hair girl with a pink hat comes out of the crowd and objects what Ghetsis said.
On a random window, an 'Umbreon' watched all the things, the pokemon has cyan bands and rings on its body instead of the usual yellow color. The girl remind 'Umbreon' of those main characters he once heard in the human village everytime he sneaked in tried to find some food. But the thing that makes it pays attention the most neither is the weird guy who is talking loudly or that girl, it looks at N and his Purrloin, the two who are talking normally as if there is no language different between human and pokemon. "What is that man?" He thinks.
At the time team Plasma leaves is when 'Umbreon' returns to its home, an abandoned house in the forest. The house once belongs to a group of human that used this place as a thing they called 'Restaurant'. Although the moonlight pokemon don't know what is it, he sure that it's once a crowded place.
After making sure that the entrance was covered, he lie on the dusty sofa, 'Umbreon' takes off his illusion, returns to the Hisuian Zorua. Due to being hit by the power of time, Zorua can't evolve nor die. He used to spend his time praticing in improving his strength and illusion. The ghost fox's favourite 'costume' is a shiny Umbreon, he don't remember how did he meet one, but the color combination and the feeling it brought never faded from his memory.
Now, his purpose has changed, he wants to be a human.
"How can weak species like human become the ruler of this world?" He always thinks about that question.
Zorua is right, human can't use a single move to protect themselves, they can't even understand our language, the language that ALL species of pokemon know. Or more specifically, human can't hear pokemon. The white fox's mind is always filled with curiosity, he wants to seek the truth, that's why he spends hours per day observing human.
Unfortunately, mimicking a human is Zorua's hardest challenge, it is not only the fact that he needs to learn how to speak human's language but also designing his own 'costume'.Pokemon can't fully understand human's words, only some like moves' name or 'dodge' they can clearly know. Most of the other words are too complicated for pokemon, he feel like he isn't different from a kid who tries to learn a foreign language. ''Why can't they use old language as before?" Zorua thinks, remembers the time when human and pokemon were as wild as the other.
Speaking human language is still possible for pokemon, thou. There is a Meowth who can speak those things fluently just by learning like what human do to learn a new language, at least that's what the pokemon rumours to each other.
And that's just the first problem... Unlike pokemon, every human has a different appearance, therefore, he can't just copy a person like he do with pokemon. Zorua's imagination is the only thing that he can't improve by training. In order to find his own 'human costume', the Normal/Ghost type gathers pieces that he like from a lot of human he has met into a drawing to have a complete body. "Today is the last part, the face and hair style!" Zorua said while coloring the clothes by some crayons that he stole from a place full of little human.
Suddenly the image of a girl he saw this morning appears in his mind "Wear a hat maybe cool!" then he draw a cap by a red crayon on the head. About the hair, the fox choses the color brown, the best color for blending in the human. Zorua remembers the spiky tea-color guy who was talking to the Purrloin.
"Alright! A mess hair like that looks cool!" He said in his mind, but reduce the length of the hair much shorter.
Finally, after a long time, Zorua has complete his first human form. Now he only needs hours of pratice to make sure the illusion doesn't have any mistakes.
Route 2
Hilda is totally confused by the guy named N that battled with her in Accumula town.
"Is it true that he can speak with pokemon?"
"What does he mean by liberating pokemon?"
"Are you okay, Hilda?" Bianca, one of two friends that started the journey with her asked with a worrying expression.
Cheren, the other friends said "You are thinking about that weird guy, right?"
Hilda nods. Bianca asked Cheren who the guy Cheren mentioned was, that time she was in pokemon centre so obviously she didn't know what happened outside. While Cheren is explaining to Bianca what happened that time, Hilda with her Oshawott fight wild pokemon to prepare for their first gym battle. Far away, a brown-hair boy who definitely not a Hisuian Zorua in disguise, he is watching them.
"I wonder if I can find a partner like them" He whispers to himself. He can ask a random pokemon for help if he want, but he truly wants to be a real human, that's mean he wants to trick the pokemon, too. When he is lost in his thought, two vine whips attack him. The boy has no problem dodging it, he looks at the direction where the vine whips came from, a snake-like pokemon, its trainer, the boy who wears red glasses is staring at him.
"Are you stalking us?" He asked the brunette.
"Okay Zorua, this is the exam for your years of learning!" The boy opens his mouth, tries to say a human word.
"No..."
"Then why are you here?" Cheren asks again.
"I...lost"
"Things turn out to be better than when I practice alone with that broken mirror." The fox thinks
Suddenly an idea appears in his mind, he slowly asks them in order not to misspell anything "Can...I..go..with...you?
Obviously Cheren who has been cautious about Zorua since the begining, doesn't agree with that, but Bianca put her hand on his shoulder.
"Cheren, it seems like he doesn't have any pokemon with him, how can we let him alone in the dark like that?! And his voice, it sound like he has been run out of energy to talk."
"I'll take that as an advice for next time" The fox under the illusion thinks
"But-" Before Cheren could tell Bianca his suspicion of Zorua, Hilda , the girl who cause the fox's attention last day, cut out the Red-Glasses sentence.
"I agree with Bianca. Cheren, if you don't like him, we can help him to catch a pokemon then leave, but until TOMORROW" She points her finger to the moon, which is shown that it's already midnight"
Cheren sigh "Even you too, Hilda? Fine, but only tonight, he's still a stalker to me"
After their conversation, they decide to start camping at the vast ground near them. This is the Zorua's first time tasting human non-leftovers food, it is warm and the taste is much more delicious than those in the trash can, of course. "You're pretty hungry, aren't you?" Bianca said, the fox-in-disguise nods while still eating.
Suddenly Hilda asks him "May I ask what is your name? It's weird for me to just call 'you' like this."
The Hisui pokemon stops for a bit. "Oh craps I forgot about the name! Gotta make one quickly"
Base on Hilda's name, he changes it a bit, Zorua drinks the soup then answers "H-Hilbert..."
"That's a cool name, it's also similiar to mine, too!" She smile "Do you think this is destiny?"
Hilbert shows a confusing expression on his face.
"Just a joke!" Hilda said. "Anyway nice to meet you, Hilbert!"
"Nice...to..meet you!" Hilbert tries to said as fast as he can while still focuses on the human pronunciation.
And that is the fox's first day as a human. Honestly I want to make Hilbert become more mysterious, but thing turned out to be the begining of a romance story. ._. Tomorrow is my exam btw, I don't think there will be new chapter soon.
I'm wondering what pokemon should be his first partner, obviously not a Unovan Zorua, I want it to be more special than that.
