Crystal and John manage to regain control over Skyvault's computer with the disc. But Skyvault will be blown up with the strappers launched by the alien computer. Crystal and John restore the computer and the virus within to call off the attack. After that, Ace arrives with a reviving gun which will cure the computer. Crystal and John succeed into beaming Ace inside Skyvault and he achieves his mission. Meanwhile Max needs John's help to take over and cure the computers in Sealab. They succeed and now Skyvault and Sealab are functioning normally. The alien computer turns against Dr. Terror as it takes over Dominion. It launches strappers to blow up a passing asteroid that would destroy all organic life on Earth. While Dr. Terror and Hacker try to stop the alien computer, the Centurions attack their forces but fail to take over the fortress where the members of the council are held prisoners.
