What is cyrokinesis?
Digimon laugh at Absolute Zero. Some of them even drink stuff at that temperature. Still, not voting for them. Voting for:
Tycho's Buster Smash from Diebuster. She can freeze everything in dozens of kilometers area down to absurdly bellow the absolute zero.Here, absurdly below= -1,000,020,000,000 Celsius to be exact
