In the meantime, the Markalite FAHP's are deployed by large Markalite GYRO rockets, and the final battle against the Mysterians' base of operations commences. Atsumi enters the dome and finds the women, alive and unharmed, in an unguarded room. Taking them back to the tunnel, Atsumi finds Shiraishi, who admits the Mysterians duped him and have no good intentions, and then returns to the dome and sacrifices himself in a final attack on the base from the inside while the Markalite FAHP's assault the base from above ground. The dome collapses and then explodes as Adachi and the women reach safety in the hills above the Mysterians' occupied land. A few enemy spaceships are observed fleeing into space, out of range of Earth weaponry, and Dr. Adachi comments on the need for continued vigilance.
