While the Fantastic Four had fought various villains such as the Mole Man, Skrulls, the Miracle Man, and Namor the Sub-Mariner, Doom managed to overshadow them all and became the Fantastic Four's archnemesis. During the 1970s, Doom branched out to more Marvel titles such as Astonishing Tales, The Incredible Hulk, and Super-Villain Team-Up (1975). Beginning with issue #42, he also had appearances in Marvel Team-Up (February 1976). Doom's origin was also a feature in Astonishing Tales when his ties to the villain Mephisto were revealed.
