A mysterious new female Crimson Cowl had formed a more mercenary Masters of Evil alongside Klaw, Tiger Shark, Cyclone, Flying Tiger, and Man-Killer, and they repeatedly battled the Thunderbolts both before and after their split with Zemo, eventually delivering an ultimatum: rejoin the Masters or be destroyed. Taking over the abandoned high-tech Mount Charteris complex as their headquarters and recruiting a small army of new members-including Aqueduct, Bison, Blackwing, Boomerang, Cardinal, Constrictor, Dragonfly, Eel, Icemaster, Joystick, Lodestone, Man-Ape, Quicksand, Scorcher, Shatterfist, Shockwave, Slyde, Sunstroke, and Supercharger-the Masters used weather control technology to launch a grand global blackmail scheme which was foiled by the Thunderbolts (now led by Hawkeye), who captured almost all the Masters and adopted the Mount Charteris base as their new headquarters.
