Bio: Kregg first appeared at the conclusion of the skirmish that took place on the planet Thraxxa between the Grayson family (Omni-man and his son Invincible) and the Viltrumite operatives who had been sent to retrieve them. Upon his arrival, Kregg surveyed the destruction their conflict had caused, and was pleasantly surprised by the raw strength that Omni-manís son had obviously brought to bear during the battle. In addition to allowing Invincible to live, Kregg granted him the title of Viltrumite Agent of Earth. Kregg further gave him a time-limit to conquer the planet. He then left with the then helpless Omni-man in chains, and took him to a heavy security Viltrumite prison to recover from his wounds.
