By now, Helmut Zemo had assumed his late father's title as the new Baron Zemo. Trying to destroy Captain America through his love for the Avengers, Zemo assembled the largest Masters of Evil yet, recruiting Absorbing Man, Titania, Moonstone, Grey Gargoyle, Screaming Mimi, Yellowjacket, Blackout, Bulldozer, Fixer, Goliath, Mister Hyde, Piledriver, Thunderball, Tiger Shark, Wrecker, and Whirlwind. Grey Gargoyle and Screaming Mimi were captured by the Avengers and Paladin during Zemo's recruiting drive, and the unreliable Whirlwind was sent off on a make-work assignment, but the rest of the Masters staged a carefully planned assault in which they managed to invade and occupy Avengers Mansion, wrecking the historic headquarters, taking Jarvis and several Avengers hostage, beating Hercules nearly to death, and forcing Captain America to watch while Jarvis was brutally tortured. Aided by Ant-Man (Scott Lang) and Doctor Druid, the Avengers finally retook the Mansion. A few Masters escaped, but more were captured, Blackout was killed, and Zemo and Moonstone were both gravely injured. Whirlwind and Tiger Shark were soon apprehended by Tigra, Hellcat and Hank Pym.
