“The Horn of the Unicorn!”

In "The Horn of the Unicorn!", Tony Stark faces off against the enigmatic warrior Unicorn, only to realize the fight is being manipulated by an unseen force lurking in the shadows. Written by Bill Mantlo and brought to life by Herb Trimpe and Keith Pollard’s dynamic art, this 1978 issue delivers a tense, mystery-driven clash with a hint of something deeper at play. The cover by John Romita Jr. and Bob McLeod captures the intensity of the moment.
