Synopsis:
The Challengers are summoned to the lab of Professor Elber and warned of an alien robot invasion. When the first robot arrives on Earth, the Challs race to defeat it. However, Prof is lost in the encounter and believed dead.

Another robot appears elsewhere, so the Challs leave to combat it. Rocky destroys a cave, but he appears to be killed in the explosion.

Ace and Red then stage their own deaths having deduced that Elber is responsible for the robots. Elber orders his robots to attack. Rocky and Prof return to rescue their comrades, having survived their seemingly fatal encounters. Together the team defeats the robots. Ace exposes Elber as a robot too. With the robots destroyed, the threat to Earth is over.
