Lodar was a battle-scarred gladiator in the Preternian slave city of Targa when he stole magic from a sympathetic Zodac, forever gaining the ability to draw power from the Eternian sun and moons. Nearly invincible, Lodar soon conquered Targa intending to free its slaves, but power quickly corrupted him. He amused himself by creating the hideous but devoted Kobolds and pitting his subjects against them in the arena where he once fought. During the Great Wars, a disappointed Zodac helped King Grayskull liberate Targa and trap Lodar with his Kobolds in the catacombs beneath the city. With Lodars remaining power they endured motionless for thousands of years until Queen Balina and her wizard Draca freed them, exposing Lodar again to the Eternian sun. In return he helped them usurp the Targan throne from Balinas step-daughter Princess Rana, turning Targa once more into a slave city. Eventually Rana sought out He-Man, who fought Lodars warriors in the arena before persuading them to join forces and overthrow Balina, driving Lodar back into the catacombs.
