Summary: A group of Native Americans comes under attack by a giant totem claiming to be a ghost warrior, who tells them to fight against those who have built upon their land. The tribal leaders call in John Thunder, who brings along his fellow Centurions Ace and Jake. While John confers with his people, Ace and Jake are attacked by Hacker. Meanwhile, the giant ghost warrior appears to John and his tribe and brainwashes them into attacking a geological research lab. John tracks down the ghost warrior and finds out that it is really a giant Traumatizer controlled by Doc Terror. Terror traps John, and as his brainwashed victims keep Ace and Jake occupied, Terror attacks the real target: a nearby space port. John must free himself and his people, and assist his Centurion friends.
