Rommbu first arrived on Earth when his race sent him to the planet in order to demand humanity's surrender before they conquered the planet. When the humans refused, he went to his spaceship, unbeknownst to him John Hunter had snuck aboard trying to escape from the police. Rommbu eventually found John and demanded that he show Rommbu a safe place to land and recharge his ship, so John led him to the inside of an active volcano before an eruption, killing him and seemingly killing Rommbu.[1]
