Fight on New Namek, Big Getti Star is in orbit
Metal Cooler Curbstomps.
Ya know, Metal Cooler can create as much units as he wants, can regenerate, adapts to the fight quickly, can fight using instant transmition and each unit gets stronger after every fight.
With Big Gete Star is overkill, it can create an unlimted amount of Metal Coolers, each one stronger than the one before.
If the Big Gete Star isnt destroyed, then Android 13 just cant kill more than 4 or 5 Metal Coolers.
