Rodak calls the monster Dilas (Grania) to Earth to destroy Goldar. Claw is also reactivated by Rodak, and now the Space Avenger faces two monsters! As Goldar battles Dilas, the creature disappears. Horonda and his men have Mikko, Gam and the Commander pinned down. Goldar comes to Miko’s assistance, but not before Claw infects Mikko with nerve gas. Horonda escapes and meets with Rodak. The two villains decide to detonate the H-Bombs. They kidnap the daughter of an army H-bomb expert, Yazowa, to force him to set the timing device. But, instead of freeing Yazowa and his daughter, Horonda and Rodak tie them to the bomb. Mikko recovers and calls for Goldar when Dilas attacks. Unaware that Yazowa has cleverly installed a tiny safety mechanism in the H-Bomb, Rodak begins the countdown to the big explosion. There is only a small, sparkling blast in which Yazowa is hurt.
