Meta-Cooler Core

After Goku destroyed Cooler with a Super Kamehameha that launched the tyrant into the sun, a surviving fragment of Cooler's body drifted through space until it was intercepted by the Big Gete Star, a massive self-replicating machine that absorbed and integrated technology and organic material alike. The star recognized Cooler's extraordinary biology and made him its central processing unit, merging his consciousness with the machine network. What emerged was neither fully organic nor fully mechanical: it was Cooler's mind directing the resources of an entire technological civilization.

The Return of Cooler

The Meta-Cooler Core's most dangerous capability was its ability to manufacture Meta-Cooler drones. Each drone possessed power comparable to Cooler's Fourth Transformation and could be repaired and upgraded by the Big Gete Star instantly after taking damage. When Goku and Vegeta confronted the Meta-Cooler army on New Namek in the film Return of Cooler, they destroyed one drone only to face hundreds more. The Saiyans were eventually captured and connected directly to the Core, which began draining their energy to power the Big Gete Star. However, Goku and Vegeta overloaded the Core by flooding it with more energy than its circuits could handle, causing a chain reaction that destroyed the Big Gete Star and the Meta-Cooler Core along with it.
