Meta-Cooler Core (SSJJ)

Meta-Cooler Core is the result of the main computer of the Big Gete Star absorbing and merging with Cooler. They served as the main antagonist in The Return of Cooler, however, in the Dragon Ball Advanced - the Big Gete Star attacked Vampa and was defeated by Broly.

Appearance
All that remained of Cooler was a portion of his head while the Big Gete Star replaced most his body.

Background
In the movie; Cooler was drifting through space after he was blasted into the sun by Goku when he was found by the Big Gete Star. While in Dragon Ball Advanced; after being revived following the defeat of the Dark Empire and Atla - Cooler returned to Age 780 and intended to better himself in order to best Frieza and take over the Frieza Force.

Dragon Ball Z
Meta-Cooler Core set a course for New Namek with the intent on draining the planet and taking the Namekians as fuel for the star. Dende learned of this terrible event, calls to Earth's warriors for help.

Goku destroyed Meta-Cooler Core's body while Vegeta destroyed his chip ending Meta-Cooler once and for all.

Dragon Ball Super
Meta-Cooler Core set its sights on Vampa to harvest its unusual core for energy and try to its inhabitants as a fuel source. However, Broly responded with a swarm of Vampa Beetles and Ba as he battle against the Meta-Coolers and Meta-Cooler Core.

Broly was able to stop the Big Gete Star and managed to separate Cooler from it - sparing him. Cooler offered to leave him alone as his debt to Broly and simply left the planet.

Power
Meta-Cooler Core was seemingly a match for Goku and Vegeta but in Dragon Ball Advanced - he was no match for Broly and lifeforms of Vampa.

Abilities
Meta-Cooler Core has the same transformations and techniques as stated on the canon wiki.
