Most characters in Hostess pastry comic advertisements never hit the big time (hello, Ding-A-Ling Gang), but one villain slipped on through. That dubious honor would go to Icemaster, an Iceman knockoff who sports a goatee to denote how evil he is.
Even though he debuted in 1979, Icemaster was totally unused until Kurt Busiek resurrected the character in Thunderbolts 20 years later. After staying out of the limelight for another 12 years, Icemaster made an appearance in Fear Itself: The Home Front #2. In a story by Christos Gage and Mike Mayhew, Icemaster is one of the heroes who pounds the tar out of Speedball. Even after all these years, he still loves his baked goods. Icemaster, you've officially arrived.
