Mistress Death believed that there was a cosmic imbalance in the universe - that there were more living than there were dead. As a result, Death resurrects her loyal servant Thanos, who is appointed the task of killing off half of the population of the universe. Not only is Thanos' power augmented by Death, he is granted access to the Infinity Well, where he realizes the power of the Infinity Gems. After much plotting and scheming, Thanos wrestles the gems from their owners and gains mastery over Power, Mind, Space, Reality, Time, and the Soul.
