Iron Man #159

In "When Strikes Diablo," Iron Man returns to Stark International after a daring rescue at the Roosevelt Island tramway, only to find himself confronting a mystery within his own ranks. Al Bido, a janitor with an uncanny grasp of chemistry and no memory of his past, begins to uncover unsettling truths during a session with the company's psychologist—truths that point to a shocking identity hidden beneath his quiet demeanor. Written by Roger McKenzie and illustrated by Paul Smith, with inks by Marie Severin, Terry Austin, and D. Hands, and colored by Don Warfield, this 1982 issue features a cover by Paul Smith that captures the tension of a man unraveling his own past.
