Ice Wave

Ice Wave (アイスウェーブ) is Frost Man's special weapon. It sends a flow of ice along the floor until it hits a wall. It can freeze enemies (and some take damage by it), and it can even freeze the lava fountains in Sword Man's level. It is Tengu Man's weakness, freezing him to the platform for a moment, allowing Mega Man to fire extra shots. In Mega Man 10, the third Weapons Archive accesses Frost Man's data and uses the Ice Wave.
