tyrant imprisoned morg and continued to siphon off his power cosmic and store it into his orbs. eventually morg escaped and went back to his master galactus, and served as herald again for a brief time. in a battle between galactus and tyrant, morg found the ultimate nullifier and used it to melt most of tyrant's body then betrayed both masters by cutting off his own arm while he tried to escape the final nullification blast (tyrant's drone attached itself to the nullifier and morg's arm thus not allowing morg to separate himself from the nullifier). his escape failed and the nullifier exploded, destroying galactus' ship and all aboard.
