A strange encounter

Oh boy this is old. And not good, so expect an unfinished (and rather bad) story.

Two shiny Pokémon encounters each other in battle, enemies from the start. But the two both face challenges that they have to make peace over to overcome- But the two also form a relationship along the way.
⚠️Please note that this story has violent, gore-like themes, strong language, and/or sexual themes. Pokemon is a game directed toward a younger audience so I want to warn readers of a younger age about these themes. Thanks!
