He is the second boss if one does not count Gorge's Sergeant, of the game. He was possessed by the ooze of Mawgu, so he could not think clearly. He had held the Myrmec Queen captive and was working for Mawgu. The heroes however first freed the Queen and afterward battled Mad King Gorge. The Myrmecs tried to break the dam during the fight, and when you defeat King Gorge the dam breaks and the water turns him back to normal.
He is later seen on Volcano Island thanking the heroes and gives them the last piece they need which is a microwave.
When the battle starts, King Gorge will stick his lianas into the ground. The tips of the lianas will sprout out of the ground and will damage you if you get hit by them. The best way to evade this is to keep walking around. When the last liana from the attack sprouts out, you have to attack that. Do this three times until all of his lianas are dead.
You then must climb on the big leaves that lead to his head. You then just rapidly attack his head until you are sent back. He will first fire leaf bombs that will trap you if you get hit by them. You then repeat the process from before. However, at the second time you attack his head, you have to watch out for his purple fire breath. When you have attacked his head enough the second time, you have won.
His name is a parody of King George, one of the names that were used by many kings.
