First Avengers Appearance: Avengers V1 #6 (Jul 1964)

A Nazi scientist who performed many acts of Infamy during World War II bringing him into conflict with Captain America and Nick Fury’s war time unit, the Howling Commandos. Zemo hid in South America for many years until he was outraged to find his arch foe Captain America still alive and part of the modern hero group The Avengers.

Obsessed with the need to destroy Cap and the Avengers, Zemo created the Masters of Evil consisting firstly of the Melter, the Radioactive Man and the Black Knight Later it was the Enchantress and The Executioner. This obsession resulted in Zemo being a recurring opponent in the early days (Avengers V1 #6, 7, 9, and 10) before being killed while battling Captain America (Avengers V1 #15).

 Note: Don’t expect to find any stories published in the 1940s involving Zemo. He was created in the early 1960s and retroactively written into Captain America’s history including being responsible for Cap and Bucky's apparent death towards the end of the war.
