Summary
An earthquake wakes a Highbreed officer, who was put into stasis and only to be awakened if the Highbreed lost the war. Per his orders, he triggers a weapon of last resort meant to destroy Earth. Mind-controlling seeds take over Grandpa Max and five others, using them as the brain for a living bomb that will end all life on the planet. The Highbreed officer refuses to believe Ben's claims of peace, and won't divulge how to stop the creature. While Gwen and Kevin try to slow it down, Ben enlists the aid of Reinrassic III to get the Highbreed officer to cooperate. Unable to stop the monster from the outside, Ben, Gwen, and Kevin sneak inside the monster to destroy it within. They manage to save the humans being used as its brain, and the Highbreed officer sacrifices himself to dispose of the creature safely.
