Ice Wall

Ice Wall (アイスウォール) is Cold Man's Special Weapon from Mega Man & Bass. When equipped with this weapon, Mega Man or Bass creates an ice column that can be pushed to attack enemies. This weapon is very helpful for Mega Man, as he cannot double jump like Bass, and it can be used to pass by spikes and reach high areas. The Ice Wall used by Cold Man however is spiked, so it cannot be stood on and used for transport. This weapon is Burner Man's weakness; using it on him pushes him into the spikes that surround his room for even more damage.
