Koga was as lost as possible tenfold. He was far from home and family, of that he was certain. Beyond that, he had no idea where he was. On the plus side, he still had his Pokemon team: Gardevoir, Charizard, Aggron, Rampardos, Alakazam, and Swampert; his sword & dagger, for emergency purposes; his Key Stones - two on each arm and one on his necklace - for each of his Pokemon that could Mega evolve; and his life, which meant he could figure out where he was and how he could return home.
As he got up from the ground, he felt several eyes watching him. When he looked up, he was struck with astonishment. Staring at him were several creatures that looked similar to Ponyta and Rapidash, except that they were varied in color, they weren't on fire, and some of them had wings.
What in the name of Arceus - what manner of Pokemon are they?! Koga thought as the creatures stared at him. He would have spoke, but he was pounced on by the pink Ponyta.
"HI! I'm Pinkie Pie! I've never seen anything like you. What's your name? Where are you from? Why do you have a sword? We should throw a Welcome-To-Equestria party! What kind of-" the Ponyta that called herself Pinkie Pie - for it had a very high-pitched feminine voice - had her mouth suddenly zipped shut. The purple Rapidash with wings walked up as its horn glowed and Pinkie Pie was dragged back by the same glow.
"Sorry about my friend, she's always excited when somepony new shows up. My name is Twilight Sparkle. You've already met Pinkie Pie here. That's Applejack, Rarity, Fluttershy, and Rainbow Dash."
"Howdy," said the orange Ponyta with a blonde mane & tail and a stetson.
"Hello, darling," greeted the almost-white Rapidash with a royal purple mane & tail.
"Hi…" whispered the pastel yellow winged Ponyta with a pastel pink mane & tail.
"And who and what are you?" said the cyan winged Ponyta with a rainbow mane & tail as she flew into Koga's face.
"Rainbow Dash!" Twilight scolded as her horn glowed again and Rainbow was pulled away in the same manner as Pinkie Pie. "Where are your manners?"
"Do you not see it's armed?! It could be a threat!" Rainbow countered.
"Perhaps if you let it talk," Koga said, gaining the attention of the group, "it could introduce itself before any hostilities arise. My name is Koga Diamond. I am a human from - " he was interrupted by a loud crack as a large tree started to fall onto the group. Reacting instinctively, he grabbed two Pokeballs from his belt and yelled, "Hold up the tree!" As he threw them, they opened to reveal his two powerhouse Pokemon: Swampert and Charizard. The moment the Pokeballs left his hands, he placed his fingers onto two of his Key Stones, which activated immediately, causing Swampert and Charizard to evolve into Mega Swampert and Mega Charizard X.
"Swampert and Charizard, I need you to move that tree away from us," said Koga. "So, as I was saying..." he paused, noticing the varying degrees of shock and fear on each of the girls' - mares' - faces, with Fluttershy hiding behind Applejack and Rainbow gaping in astonishment.
"Great work, you two. Return and rest," Koga said as he pulled out the two Pokeballs from before. "I think we should find a safer place to discuss matters further."
Author's Note - Thanks for reading this! I wanted to clarify on one thing before you leave: I know you can't Mega Evolve more than one Pokemon at a time in the games, and though I understand the reason one is unable to Mega Evolve more than one Pokemon at a time in that instance, I believe that more Key Stones equals more Mega Evolved Pokemon. With that, one must work extremely hard to obtain more Key Stones, and at some point I plan on making stories regarding how Koga was able to obtain 5 Key Stones. Maybe after I finish this one.
Also, criticism is much appreciated, so please review.
