You were walking down one of the routes with one of your Pokémon by your side, on your way to the nearest town. You've sprayed yourself yourself with plenty of repels, so there were barely any Pokémon in your way.

Then, you feel a Pokémon hit you hard in the back of the head, but thankfully all that came from it was pain.

"Oh, sorry 'bout that!"

You turn around to see a fellow trainer carrying a billiard cue in his hands. "Didn't mean to hit you!"
