Johnny is the real powerplayer nerd, he cares about gold and magic items only.
If he only could he'd spend the all day killing orcs with his blade, complaining about the small amount of treasure they leave behind.
He based on Might. He's the tank of the party and, as tradition teaches, he can withstand tons of punishment and focus the enemy hate to help his low health fellows.
With him as a leader you party will get a boost to HP and/or strength.
