The Avengers #107

In "The Master Plan of the Space Phantom!", the Avengers are trapped in a deadly game of cat and mouse as Black Panther, Scarlet Witch, Iron Man, and Hawkeye remain captive under the Space Phantom’s eerie control. With Captain America drawing on his past battles with HYDRA to track his missing teammates, and Vision torn between his own identity and the tempting offer to inhabit Wonder Man’s body, the stakes rise in this pivotal 1973 issue written by Steve Englehart and illustrated by Jim Starlin and George Tuska, with inks by Dave Cockrum and Jim Starlin, colors by Glynis Wein, and letters by Denise Vladimer. The cover by Rich Buckler captures the tension perfectly.
