Ep. 10: Alien King Nikochan attempts to destroy Earth after abducting Arale and Gatchan

10

The Alien King Nikochan kidnaps Arale and Gatchan with the goal of destroying the Earth. However, Gatchan consumes the alien spaceship, thwarting the immediate attack. While Dr. Slump constructs a replacement vessel, Nikochan becomes increasingly distressed by the welcoming attitude the Earth's inhabitants display toward aliens. This positive reception drives him to madness. Although the new spaceship is eventually completed, it never departs from the planet, leaving the Earth intact despite the initial threat.
