Lord Grog used to be the leader of the goblin army, until he was killed by Xane. His model is based on the goblin warrior from Terraria.

He wasn't very good leader, because he blamed Smurg for every mistake he made, and every time the goblins get attacked, he only shouted: "Every goblin for himself!" and never made any battle strategies. Also, he almost always failed to remember the names of his goblins.
