Marvel: Organic Ice Form

Robert Drake (Iceman)
He has the ability to not only cover his body with ice but to actually become organic ice. Though the appearance is similar, Iceman is now actually translucent in his ice form. Iceman is virtually indestructible in this form and was able to rebuild himself. In his ice form, he is able to use the moisture in the air to form spikes, shields and attach other extra appendages to his body. It is currently unknown if Iceman would be considered immortal.

Due to the amoutn of water on Earth, Iceman has a virtually unlimited supply of moisture since it's always present in the surrounding air or environment. Even desert air has sufficient moisture content for him to make temporary practical use of; however, the mental effort needed to employ his mutant power under these circumstances could eventually fatigue him and render his freezing ability temporarily dysfunctional.
