Welcome to the world of Pokémon- a world beyond what you know from the Game Freak games! In this world, Pokémon fight, and if they fall in battle, they wind up stuck inside a Poké Ball until they are sent out. It was a standard battle in a stadium floating in midair, most likely representing Elesa's Flying-type Gym in Mistralton City, and two Pokémon were standing in said stadium: the elegant Grass-type princess Lilligant, and the Melody Pokémon Meloetta (Aria Forme).
"Ah! Isn't it perfect weather outside for an epic Poké Bros. battle?" Lilligant asked the Mythical Pokémon standing beside her, stretching.
Meloetta snapped to her senses from her daydream. "Ah! Oh. Sorry, Lilligant," she* said uneasily as she looked up at the sky. "Yeah, the weather certainly is beautiful right now...the Forces of Nature** did a fantastic job on today's weather! And Espeon's weather forecast was spot on, to say the least!"
Suddenly a voice came over the PA system: the voice of an announcer Exploud. "And in this corner, it's the evolution to Scyther, it's the original Bug/Steel-type...capable of Mega Evolution, it's...Scizor!" A Poké Ball that was lime green and grey (representing the Bug- and Steel-types) landed on the floor of the stadium, and what popped out was a primarily red humanoid Pokémon with small, silvery grey wings and claws that looked vaguely like small heads. A red-and-grey stone shaped like a cat's eye marble hung around his neck on a piece of string. It was Scizor, a returning veteran to the tournament in the same way as Fennec and Fearow were. Scizor demonstrated the sharpness of his claws quickly before grabbing his Mega Stone with one claw, careful not to shatter anything.
The Exploud laughed a hardy laugh. "Very amazing, Mr. Blade! An awesome entrance!" he exclaimed, then started talking again, this time for the other side of the battlefield. "And in this corner, we have the small black hole of Normal-types...please give a warm welcome Munchlax!" An entirely white Poké Ball with a red streak in the center (Premier Ball) dropped onto the battleground, and a Munchlax burst out. This particular Munchlax wasn't quite as laid back as other Munchlax, having been in Poké Bros. since the first tournament. "Now, let the fight begin!"
Meanwhile, up high in a faraway realm in the sky, a Swanna stood in front of what looked like a psychic cauldron, repeatedly flapping one wing in the sense that he was cheering for the competitors in the current battle.
"...and it's a claw to the left, a sock to the nose, a Low Kick to the right, a Bullet Punch, a...random Return attack? Regardless, this is one battle that no hero is going to give up on any time soon!"
Swanna flaps his wings vigorously. "Scizor and Munchlax here are my kind of Pokémon," he said happily as he shot a Bubble Beam attack toward the sky. Then he realized what Umbreon had said earlier in the day: their world was going to be invaded. 'But I do hope our world isn't disintegrated within the next five minutes...' Swanna looked toward the sky, then back to the fight.
A/N: Sorry if this isn't the most eventful chapter in the world, but it's the first chapter of what I hope is truly epic story!
