Members: The Melter, the Radioactive Man, the Black
Knight, and later the Executioner and the Enchantress.
The original Masters of Evil were organized by Baron
Zemo, a former Nazi scientist who first fought Captain
America during World War Two. Learning that his foe
had been revived, Zemo vowed to get revenge. To engage
Captain America's companions in the Avengers,
Zemo enlisted Thor's enemy the Radioactive Man, Iron
Man's adversary the Melter, and Giant-Man
and the Wasp's
nemesis the Black Knight, and lured the Avengers into
battle on the streets of New York. Although his accomplices
were subdued, Zemo escaped and soon allied himself with
the Asgardian gods the Executioner and the Enchantress.
Their scheme to turn Thor against the other Avengers failed,
as did their creation of Wonder Man as a pawn to use against
them. Zemo finally had the Executioner and Enchantress
free the Melter and the Black Knight from jail so they
could all join forces against the Avengers. (The Radioactive
Man had been deported to his native China.) While the
rest of the Avengers defeated the assembled Masters, Captain
America fought Baron Zemo in South America, a battle that
ended in Zemo's accidental death.
