Nemesis lives on as the Nth Degree. Jesse continues to threaten the Star Sheriffs with the Cobalt Blue Blaster. The Seventh Cavalry flies off to attack the Outrider Planet. But the Nth Degree causes the Planet to swerve out of orbit, putting it on a collision course with Planet Yuma. With Colt still injured, the three other Star Sheriffs fly off to stop the Nth Degree and prevent the collision. They defeat a Renegade Unit, then fly into the Outrider Planet through the barrel of the Cobalt Blue Blaster. Jesse fires a blast while they're in the barrel, but the Ramrod fires in the opposite direction. The two blasts meet, cancelling each other out so that Planet Yuma is safe. Jesse pilots a powerful Renegade unit to attack the Star Sheriffs. Jesse traps the Star Sheriffs until Colt, who is still injured, arrives in the Bronco Buster to save them. Jesse follows the Star Sheriffs to the chamber of the Nth Degree. They defeat the Nth Degree and Jesse and cause the Outrider Planet to explode back into the Vapor Zone before it can collide with Planet Yuma. The New Frontier is safe.
