I continued fighting the horde on Earth, before taking the fight to Hell once more I was then was decommissioned Some years later though, i was called upon again to fight the hellish force attacking a space station, prompting me to return to Hell where i defeated the Mother of All Demons. In order to save Earth, I decided to close the portal from inside Hell and continue the fight against the demons The Mother's sister, Resurrector, wanted vengeance, thus teleported me to Earth to kill me there. But i fought my way to Hell again and defeated her there.
