In case anyone was wondering,

[hider=Info on Rin]
Poochyena has a very keen sense of smell, allowing it to find and chase its prey with ease. It takes a bite at anything that moves, and makes the hair on its tail bristle out to try to intimidate its foes. Known for its tenacious nature, it chases after prey until the victim becomes exhausted. If its prey strikes back, it may turn tail. It is omnivorous and will eat anything. This Pokémon lives in grasslands and forests.

It might be good to just have a look to get an idea of what the pokemon is like? I know this is a chill RP but it makes sense to at least do that much. Like Luke. Most Serperiors glare at everything to test them. If they back down, then he won't fight them full force. If they meet his gaze, he's more than willing to fight them with everything he's got. And that's just according to the Bulbapedia. That being the case, you don't have to make your pokemon like that just maybe.. try to explain why they aren't like the norm?
