Avontuur Classics #1837

In "Het kopie-mysterie!", Tim and Tam Robinson find themselves caught in a twisted game of identity when the exiled alien Zurko traps them on an asteroid and creates an army of Tim duplicates to seize control of his home planet, Zytrox. With the help of June and Craig Robinson, the family must race to stop Zurko’s plan, uncovering a shocking weakness in the clones—high-frequency sound—before the planet falls.

In the depths of an alien cavern lit by eerie artificial glow, Captain Venture and Lieutenant MacKay face the unknown after their ship crashes into a hidden sea. Stranded in a world of towering trees and strange silence, the two must set aside rank and work together—sharing not just survival, but their first names for the first time.
