You have been fighting Cooler for a long time, both of you being battered after hours of combat with eachother

Cooler stands in front of a waterfall, he suddenly gains more muscle mass than he had before, and the white carapace on his head has increased in size, and he’s at least 10”6 now, doubling your height

Cooler: Time To Die!

A visor suddenly covers his face… this is Coolers final and strongest form.
