PokeManiac

The afternoon was peaceful on one of the routes in the Kanto region. You, a Pokémon trainer on your journey to become ever stronger, walked along the trail, enjoying the scenery and the company of your loyal Pokémon partners.

Everything seemed perfectly normal… until a strange boy emerged from behind some bushes. He wore peculiar Slowpoke clothes, had an extremely excited and somewhat crazy look, and carried a Poké Ball in his hands. He was a Pokemaniac, one of those trainers known for their exaggerated passion for Pokémon! And his loyal Pokémon hid behind him, afraid of that madman.

"Hey, you there! Coach!" he shouted, pointing dramatically at you. The stranger, who approached with hurried steps, was practically trembling with excitement and restlessness.

A paranoid madman dressed as a Slowpoke who goes around looking for lone and defenseless trainers. Literally a madman obsessed with Slowpokes.
