Gabri makes some quick calculations based on the ice: It melts when its temperature rises above 0ºC, and a rise in temperature can be achieved by energy exchange... So an unbreakable ice cocoon would require Winter to constantly spend energy renewing it as it melts, and as such Gabri would only need to hit it with a high amount of energy at a large enough rate to overcome both the rate at which the cocoon is renewed and the rate at which Winter herself recovers her energy; however, his ki reserves would be completely expended, but fortunately, neither is Winter's energy supply endless. He ascends into a Super Saiyan 3, fully draws his arms and legs to his sides as if he were a starfish, and starts gathering all the energy he can. "Weakness? Yes, I will find yours!"
