After Glenn destroys the android Thor in self-defense, Kolos captures him specifically to create an android duplicate. The plan uses the duplicated Glenn to infiltrate the National Intelligence Agency from within, allowing further thefts of electronics needed for more duplications.

Foreshadowing: The earlier thefts require electronics, and inserting an android into the NIA provides continuous access to technology.

The androids can be destroyed by zapping their heads with the pulsed laser beam located in Dornheimer's laboratory. The real Dornheimer reveals this weakness while imprisoned with Glenn, explaining that the androids' mechanical brains are vulnerable to concentrated laser fire.

After being duplicated, android Dornheimer declares himself head of the android master race and seizes control from Kolos. He orders the Thor androids to bind Kolos and begins duplicating Lisa, seeking to lead the invasion himself rather than follow the original alien's plan.

Kolos refuses to duplicate Lisa, triggering a direct conflict with android Dornheimer who wants to proceed with her duplication. This becomes a pivotal power struggle because Lisa represents the human element Kolos has kept intact, possibly hinting at his own unresolved humanity.
