March, 1986: Windfall, former member of the Masters of Disaster who now goes by the name of Wendy Doe, is happy to be allowed to move in with Gabrielle Doe (Halo) and Tatsu Yamashiro (Katana). Meanwhile, the Masters of Disaster (joined by their new member Syonide), carrying the DNA samples of their dead former employer Baron Bedlam, meet their new employer – Kyack, warlike leader of the underground people. Elsewhere, Cave Carson and his team – Bulldozer Smith, Christie Madison, and Johnny Smith – while traveling underground in the Mighty Mole, are captured by a mind-controlled Prince Raynor. Sapphire Stagg Mason convinces her husband Rex Mason (Metamorpho) to get the Outsiders to rescue Cave Carson, whose latest expedition was financed by her father, Simon Stagg. After Looker feels she is summoned by the Abyssians for help, she, Katana, Halo, and Windfall are transported directly there and learn that Abyssia is threatened by other underground realms. The current leader of Abyssia, Rema, explains that Abyssia has been caught in a war between two underground realms, one led by the evil Kyack and the other led by good King Nobic, father of Prince Raynor, who has lately begun attacking Abyssia with his Kryptonian-level powers.

As the male Outsiders enter Kyack's castle, they find captured Abyssians who explain that the female Outsiders have been taken away to be executed. Upon learning that he lives again, Geo-Force vows to kill Baron Bedlam. Baron Bedlam attempts to kill the female Outsiders by exposing them to the powerful meteor's radiation. The male Outsiders arrive and battle the Masters of Disaster. Bedlam uses a focusing device on the meteor that he plans to destroy Markovia with in one powerful blast, and the betrayed Kyack fails to stop him. Starstriker arrives with his mind-controlled pawn Prince Raynor, planning to absorb the meteor's power himself. Heatwave and Coldsnap are somehow merged into a single being. After a battle, the Outsiders free Raynor, who destroys Baron Bedlam's device and vaporizes the Baron himself. Kyack is arrested and replaced by an elected governor, and Cave Carson and his crew are freed. At a peace banquet afterward, Princess Vee-Raa joins the Outsiders and travels with them to the upper world, where she has super-powers. Carson promises to keep his findings out of Stagg's hands.
