NPC Proposal
A man comes up to you when you reach a point in the cave, not too far in, and starts to speak to you.
"You're a trainer, I see. One badge, not great but you're getting somewhere I guess. Allow me to introduce myself. I am the competitive pokemon guru,
Chou Toshio . Hmm, there's a lot of tough steel- and rock-types in this cave, strong fighting moves are a must. Here, take this Fighting Necktie to power up your fighting moves!"
Chou then hands the player a black belt.
"Well, good luck on becoming a good competitive pokemon player. I'll be watching your progress, and deleting any posts I dislike."
Chou then walks off into the cave.
