Cosmium is a gravity-repelling metal mined on Pluto and reduced to a substance called Gravitex. Nucleo, the Mad Martian, is suspected to be responsible of the theft of large amounts of the Gravitex.

Following Nucleo to the planet Doba, Commodore Rex Clive of the Space Rangers and Stella Dawn of the STARS encounter one of the previously-thought extinct Lizardines sent by Nucleo to attack them. Rex kills the creature, which he thinks is the last of its kind.

After being attacked by the Lizardine, Rex and Stella are attacked by two "Super Robots", as Stella calls them. The robots are "immune to jet guns". The pair escape them by going into den of the Lizardine.
