Leader: Ultron-5 (as the Crimson Cowl)
Whirlwind, Radioactive Man, Melter, and Black
The second group of costumed criminals calling themselves
the Masters of Evil were organized by the robotic Ultron-5,
creation of Henry
Pym (then known as Goliath), who concealed his identity
from the others in the guise of the Crimson Cowl. Ultron
planned to launch a surprise attack on the Avengers
in their mansion
headquarters, and maneuvered the Avengers' butler
Edwin Jarvis to sell them the blueprints to the Avengers'
security systems. Their raid was successful and the Masters
took the Avengers captive. However, the second Black Knight,
who joined the Masters in order to betray them to the
Avengers, initiated the Avengers' rescue. The second Masters
of Evil were defeated by the Avengers, but Ultron-5 escaped,
to plague the Avengers subsequently without human accomplices.
Klaw, the Melter, Radioactive Man, and Whirlwind challenged
the Avengers a second time, but were easily defeated.
