Great Glacial Aegir

Great Glacial Aegir is an Ultimate Move performed by Shoto Todoroki using the Half-Cold Half-Hot Quirk and the Flashfire Fist: Phosphor technique.

Description
Shoto builds up his fire and ice, rushes toward his opponent, hits them with his fist and unleashes a massive wave of cold fire, able to cover a massive section of terrain completely in ice. It has also been shown to be used like a explosion as it spread around Gunga Forest to stop a powerful explosion.

This move was first used against Dabi during the Final War. This move's power was enough to completely extinguish Dabi's inferno he made with his Blueflame Quirk, and to temporarily incapacitate the villain. It was used a second time at a more powerful level to extinguish Dabi's explosion.
