The New Addition
"Hey, sport. Captured a new Pokemon. He's a dark type like you, and supposedly he's a legendary. You should say hi. Trainer's unsure if he's going to be a part of the main six or not. She wants to see how well he is with the others, first. So get off your ass and say hi."
Greninja scowled as he was rudely nudged out of his meditation zone. Blaziken just chuckled and grinned at him as he walked away smugly. Greninja rubbed his shoulder, sighing, before standing up. Their trainer had just acquired a new Pokemon, and from the sound of it, Blaziken was the one the trainer used to help acquire it. And why wouldn't he be? Blaziken grew very powerful with that mega stone of his. Cheap.
Greninja wasn't out during that battle. So he didn't quite know how it went; just that in the end, his trainer obtained a legendary Pokemon. The frog wandered around, searching for the new Pokemon, but it didn't take him long to find them. The other Pokemon that the trainer currently had out were staying far away from the new addition to the team, and he could see why. He, she, or it looked so...intimidating. The way the darkness flowed about it irregularly, that one eye that peeked from under that crimson maw. Scarf? Head decoration? Greninja didn't know what that was. He shivered. But he couldn't and wouldn't show weakness now. He was the second first totally first, shut up. best Pokemon, and he had to be an example for the others!
Greninja hopped up to the newbie.
"Hey...I...I heard you're new." How does one be social? Do introductions? "...I'm Greninja. Nice to meet you." Greninja stares at this being, trying to see if he could recognize this "Legendary Pokemon".
"..."
...nope.
"...er...who are you?" Greninja asks, head tilted, still keeping his guard up just in case this Pokemon turned out to be a hostile one. He wasn't well-versed in legendaries. He only knew of Xerneas and Yveltal, Arceus, Mew, and something that started with a Z that lived forever alone in a cave somewhere.
