Hedgor is the leader of Stompede gang. He created it by punching other gargants from being lazy into action. Even Brodd himself was forced to listen. Several Man-crusher gargants and few other Mega-Gargants joined Hedgor because of his strength, loot and overall destruction he brought.
He is loud, strong and suprisingly smart for a gargant. Every pipsqueek that confronts him will most likely end under his huge feet.
