Thunderball joined the Masters of Evil alongside the rest of the Wrecking Crew, and took over Avengers Mansion. As part of this "Siege of Avengers Mansion", the Wrecking Crew, along with other Masters as Tiger Shark and Mister Hyde, beat a drunken Olympian demigod Hercules nearly to death. However, they were drained of their power by Thor in retaliation. Thunderball was later protected from the Wrecker's vengeance by the Thing.
