Grodus

Grodus is a Metagross and leader of the X-Nauts. His goal is to awaken the treasure that sleeps behind the Hundred Thousand Year Door and use it to wipe out humanity and re-establish the Alakagross Civilization. In order to accomplish this, he attempted to kidnap and turn Squealer to his side to get him possessed by the treasure. When this did not work, he took him by force behind the door.
