Morg was a simple executioner on the planet of Caraner. It was a medieval world of war and retribution, until the day the world devourer Galactus consumed it. The selfish executioner was spared the fate of the other inhabitants of Caraner, because he foolishly opposed Galactus. The world devourer selected the ruthless Morg as Herald. He would later replace the Earth girl Nova (Frankie Raye). Morg lacked the compassion for life that Frankie Raye and the other Heralds possessed. Instead of finding dry barren planets for Galactus to feed, Morg chose worlds that were teeming with life. On the planet of Bastion he discovered an immense power source that was known as the Well of Life. Morg bathed in the waters of the well. He gained tremendous mystical energy, which augmented his already enormous cosmic power. He eventually led Galactus to the planet to feed Due to his low morality, Morg’s position as Herald was contested by the Silver Surfer, former Herald of Galactus. The Silver Surfer gathered his fellow ex-heralds Firelord, Air-Walker, Terrax and Nova to confront Morg. Nova lost her life in the battle. Terrax the Tamer brutally defeated Morg in a vicious cosmic confrontation and kept the executioner’s ax. Galactus resurrected Morg once more but reduced his power level, making him equal to the other heralds.
