>>31298592Rock leader, gym is a lonely rock in the middle of a dusty savannah, looks almost like Uluru.
There are two paths in the gym; one on the outside, one that goes inside the rock. The battles of the outer path is always stuck in a sandstorm, while the cave-path always has Stealth Rocks up.
The outer path's trainers focus on defensive tactics, stalling and playing it safe, whilst the trainers inside focus on raw power, usually via costly tactics.
The gym leader is part hiker, part zen monk/dirty hippy. He explains how his gym focuses on Rock types, who are made defensive but usually have great offensive prowess. His gym focuses on teaching both these sides to Rock pokemon.
The slots with two pokemon show which pokemon he'll use; if you went through the cave path, he'll use the top one. Arrive via out path, the bottom one (e.g. Carracosta). Same goes for the TM you receive, cave gives you Rock Polish, outer gives you Rock Tomb.
The Path badge represents the solid stone and jagged crystals of Rock types, linked together but distinct.
I'll rate all yours in a sec, sorry
