They're not simply drones following orders. They're biomechanical entities with genuine intelligence and autonomy, which is why backup versions with amplified powers were created.

The very existence of the Kal reveals something unsettling about their purpose: they were built with intelligence precisely so they could succeed where drones would fail.
