Eternal. Nihilist. Madman. Would-be lover of Death itself. Thanos of Titan is all these things - and even before he created the Infinity Gauntlet and decimated half the universe, he was still a mighty force to be reckoned with. Here, collected in one volume for the first time, is the complete story of Thanos' first life - and first death. Witness as Thanos targets Captain Marvel and the Avengers in a bid to become a god, manipulates Adam Warlock, and finally lays siege to the Earth itself! Guest-starring Daredevil, Spider-Man, the Thing, Moondragon, Drax the Destroyer and more! By cosmic mastermind Jim Starlin!
