Trainer: Go Pikachu!
Pikachu: No, forget you. I've worked my whole life fighting these damn animal-things and my reward is getting my ass kicked by bigger animal-things. So next time you want to kick someone's ass indirectly by kicking their animal-things ass with your animal-things ass, which is me, you can go fight them yourself, you pathetic piece of stuff.
Trainer: *Wipes a Tear from his eye*
My general perception of how pokemon really feel about their life.
