El Toro, Santo Rico's first super agent, was an early opponent of Henry Pym, then crusading against Communist agents as Giant-Man. He had rigged an election to become president of Santo Rico, but he was swiftly defeated by Giant-Man and the Wasp. There, he was recruited by Madame X for the Bratislava Complex. El Toro acted as Madame X's aide, bodyguard, and second in command of the Bratislava-based People's Defense Force.
