UnrevealedIcemaster

A true man of mystery, the Icemaster’s origin and history remain unknown. He once plotted to create another ice age, but his plan was stopped by the Human Torch. Much later, he was somehow contacted by the Crimson Cowl to join her assemblage of villains in the largest version of the Masters of Evil. At the time, the Masters embarked on a most ambitious plan: extorting a huge fortune in blackmail money from the world's governments by subjecting various major cities to phenomenally powerful artificial storms. While this kept heroes around the world occupied by forcing them to deal with the effects of the storms, the Thunderbolts confronted the villains at their headquarters at Mount Charteris, Colorado. After the final battle, Icemaster and the others were defeated and placed in custody.
