Er was eens... de ruimte

A message from the planet Leto has informed Omega that the robots are again in rebellion against human beings; Peter is sent to Leto with his friend Metro, but it's a very dangerous mission.

It's time for the friends to return to Omega; in the spaceship that carries them, Psi gets the strange feeling of being monitored; they meet a very strange commander.

After having accomplished their mission on Leto, Peter and his friends are on their way back when they witness a strange maneuver in space.

Peter makes an emergency landing on the planet Apis; he meets the last survivors of a species that inhabit the planet and are in constant danger.

Peter and Metro visit the planet Yama where they hope to find Psi, who is imprisoned by the enemy; they have one great advantage over the robots: emotion.

The capital of Yama is a flying spaceship heading to Omega; Peter and Metro are on the ship and still couldn't free Psi.
