Chapter 1: Begin

Sylvie huddled under the tall leaves of the bush, slowly eating the Watmei berry she found while roaming the wilderness.
"Sylvie."
Sylvie turned around, to see Sarah padding towards her, ribbons floating around her head.
"Lets be careful, earlier today the scouts around the town saw two trainers leave Nuvema Town with a stash of Pokeballs and Pokemon. They are sure to go after us, non-native Pokemon and all.
Sylvie nodded, pricking her ears to listen for the crunching of human feet.
They were Sylveons, rare Pokemon that came here from Kalos, that now lived in Unova due to... extreme circumstance. They both wore shiny seashell necklaces that were from their native Eevee Clan in Kanto, fabled to summon the legendary Yveltal and Xerneas.
Listening carefully, Sylvie heard a few, heavy feet pad by.
"Hey, Zachary, what should we catch? I mean, Oshawott and Snivy seem to need a little oomph to back up their technique."
Sarah glanced at Sylvie worrisomely. Trainers talking about catching Pokemon was NEVER a good sign.
"Sylvie. Lets go swim together to the beach just ahead so we don't have to worry anymore on Route 1." mouthed Sarah.
"But... you don't swim well, and besides, berries are rare over there! A Milotic could attack us!"
Sarah replied, "Its the only way."
Glancing out of the tall grass, Sylvie made sure the trainers weren't looking at them, then ran across to the river.
Sarah did the same, but not very quietly.
"Ow!" cried a little Flebebe. The tiny creature drifted away on the wind. Sarah sprinted for the berry bushes, but it was too late.
"Dude! New Pokemon! And one is shiny!" cried the boy, his eyes almost as wide as dinner plates.
"I bet they're super powerful!" replied the girl, tossing a red and white Pokeball as she spoke.
"Go, Snivy!"
A green, white and yellow Pokemon leapt out, glaring at the Sylveons.
"I have never seen this species, even after years in Juniper's lab. Hmph. I think I'll demonstrate my power!" mumbled the Snivy.The Pokemon tackled Sylvie, seemingly sniffing the Sylveon's scent out, and pinned her.
"Let. Go. Of. Me." growled Sylvie, clawing the Snivy's belly.
Getting back up, she saw that Sarah wasn't doing well. The Oshawott had used Water Gun and damaged Sarah, despite Sarah being, like, 45 "levels" higher. Now, Sarah was struggling to land a hit, blasting Oshawott with Moonblast repeatedly.
"Snivy! Use Vine Whip!"
Two powerful green vines came out of Snivy's neck, and whipped Sylvie, blasting her into the trees.
"Great, Snivy! Take a good rest!" the girl said, and Snivy was sucked back into her ball.
"How horrendous. Being captive. Those humans want me for my shiny pelt, as far as I know." growled Sylvie.
Launching herself off the branch, she landed on Oshawott, tackling him and using Trump Card at point-blank range.
"Grr..." cried Oshawott.
Oshawott fainted, and the boy called him back sadly.
Just as they were going to flee, the humans started to throw balls at them, running almost as fast as Speed Deoxys.
"Run!" cried Sarah, sprinting towards the river.
Just as Sarah plunged into the icy water, the boy threw a wad of sleep powder, and Sarah started to weaken.
"Flee... Let them get me instead of you..."
Just then, Sarah sunk into the river, and a ball caught her. The ball floated on the water, rumbling as Sarah clearly struggled, then a burst of light.... and Sylvie lost Sarah to the humans.
"NO!"
Tears stinging her like Beedrills, Sylvie plunged into the water, quickly swimming away.
Just as the boy picked up his ball, the girl pointed her finger at Sylvie.
"The shiny one is getting away! Zachary, do you have more Foongus sleep powder?" she cried.
"Zachary" reached into his blue bag, to come up with five Potions, ten Pokeballs, his fainted Oshawott... and that was it.
"Curses! No powder left! We'll just have to capture her the hard way."
A smile crept across the girl's face like a Seviper in stealth mode.
"Well, then I have a special ball Mom gave me that should do the trick, but first lets try a few Pokeballs." said the girl. Zachary nodded, and ran towards Sylvie.
Swimming harder, Sylvie kicked up more spray as she desperately tried to get to the beach ahead.
Beneath her, a giant Milotic glared at Sylvie's belly.
"A non-water type. She doesn't deserve to share the water with us."
Without warning, the rainbow-colored serpent leered up, and blasted Sylvie backwards into Zachary.
"Go, Pokeball! Don't let go of that Pokemon!"
The smooth ball hit Sylvie's leg, and darkness came over her.
Sylvie struggled to stay awake, and pushed against the plastic.
"Don't keep me! I want to get Sarah free!" cried Sylvie.
If balls had minds, the Pokeball seemed to regret trying to capture her. In a burst of blue light, Sylvie came out, a little ruffled.
"Aargh! Almost had it!" cried the girl, stamping her foot.
Taking out a black ball, Sylvie barely had time to get on shore and shake her fur out before the ball hit her.. and darkness overwhelmed her senses.
Before she blacked out, the girl screeched, "Yes! My first captured Pokemon!"
All went black.

Author's Note: I renamed Sabrina Sarah because it sounded a lot more like the word "Sylveon". How did you like the first chapter?
