Show Mistress Death with our Thanos swag how much she means to you! Thanos is known as the' Mad Titan' or the' Avatar of Death' that I think he earned with the Guardians of the Galaxy in a Mario Kart game. The winner got the Gauntlet of Infinity! Now that I'm thinking about it, I should probably go back and read that storyline again. Do you want to be a Thanos fan? Then some of this stuff you need!
