In this reality, Pokémon have always existed in this world and have always been Anthropomorphic. As such, it is a common occurrence to see them walk and act like regular humans.
Now, back to our story.
You were minding your own business when you were suddenly attacked by a rogue Gallade! This Pokémon seemed to be completely rabid, his eyes sporting a look of unrivaled insanity.
"Oh no you don't!"
A voice can then be heard crying out. Then, a cross-like slash hits the Gallade from behind! It was an X-Scissor! The Gallade fainted on the spot!
Then, an orange, crustacean-like girl appears behind the downed Gallade. She was carrying a huge, segmented stone on her back, as a shell for her. This must be a Crustle.
"Hey, are you all right? Nothing broken, I assume?"
The Crustle girl spoke up, addressing you with a slightly concerned tone.
