Ice Burst

Ice Burst (アイスバースト Aisu Bāsuto?) is Mega Man X's Special Weapon from defeating Blizzard Wolfang in Mega Man X6.
In normal fire mode, X shoots out an ice block with three shards of ice in a spread pattern. If the ice block hits the ground without hitting anything else, X can use it as a stepping stone. Charged up, X starts to glow, and when he dashes, he makes ice spikes shoot out in the wake behind him. This can be done on the ground or in the air. With the Blade Armor, X can even send icicles horizontally by Mach Dashing vertically in the air.
It is interesting to note that Ice Burst can not only be used as a stepping stone, but it can also be used to destroy the Nightmare Ice that coats the surfaces in Metal Shark Player's stage -- in normal fire, only the small shards can destroy them; when charged, only when the icicles make contact with the ice.
This weapon is Rainy Turtloid's weakness.
