Avengers #55 🔑

1st Full Appearance - Ultron05

Avengers Vol. 1 #55, published in August 1968, is a major Silver Age key issue featuring the first full appearance of Ultron—revealed to be the true identity behind the mysterious Crimson Cowl introduced in the previous issue. Known here as Ultron-5, this marks the beginning of one of the Avengers’ most iconic and enduring villains.

Ultron is a sentient robot with advanced AI, originally created by Hank Pym (though that detail is revealed in later issues). His hatred of humanity, twisted intellect, and father-son conflict with Pym become central to Avengers lore—and a major force in the MCU decades later.

With the Masters of Evil still active and the Avengers vulnerable, Avengers #55 delivers action, betrayal, and one of the most important villain reveals in Marvel history.

Written by Roy Thomas and penciled by John Buscema, this is a must-have for Avengers and Ultron collectors.
