CHARACTER BIO: Professor Gregor Shapanka was a scientist of Hungarian birth who was obsessed with immortality. Deciding that cryonics were the first step towards his goal, he entered into the employ of Stark Industries in order to find some means of financing his research. Shapanka attempted to steal directly from Stark Industries' head, Tony Stark to finance his goals. When he was caught and fired, he stole technology from Stark Industries to create a costume containing cold-generating devices.

He first appeared under the name Jack Frost in Tales of Suspense volume 1 #45, and adopted the name Blizzard in his next appearance, Iron Man volume 1 #86. On several occasions, he worked alongside other villains in the employ of the multimillionaire Justin Hammer. He somehow temporarily gained cold-based powers that were inherent and not technology-based (at this point he also went through a deep transformation in personality, isolating himself from the rest of humanity), but he lost these powers at some point after a battle with the Hulk. The Blizzard was killed by the time traveler Iron Man 2020 (Arno Stark, a descendant of Iron Man) in Amazing Spider-Man Annual #20.

Donald "Donny" Gill was a criminal who was given either Shapanka's original Blizzard costume or a close duplicate of it by agents of Justin Hammer. He first appeared in Iron Man volume 1 #223. He was occasionally partnered with the Beetle and Blacklash (also known as Whiplash) as the "B-Team".

After Whiplash's death, Donny briefly became an employee of MODOK in yet another world takeover, but was quickly defeated by the Avengers. Angered by the fact that he had lost out once again, he found She-Hulk in a bar and preceded to freeze her in a block of ice, which she quickly snapped out of. However, as She-Hulk had had a hard day anyway, she refused to fight Donny; instead, she had him sit down next to her and carefully got him drunk before handing him over to the police.

Although the replacement Iron Man (James Rhodes, later codenamed War Machine) convinced the Blizzard to leave Hammer's service and attempt to reform, he eventually returned to crime and to his old employer. Much later, Abner Jenkins (the Beetle, now codenamed MACH-1) convinced him to join his new team of Thunderbolts. He is currently trying his best to reform. Very meek for a former super-villain, he has some trouble asserting himself. Donny is now part of Thunderbolts Team B and busy apprehending super-villains for the Commission on Superhuman Activities.

All Blizzards had the same powers which were derived from their costume. The original costume used by all three Blizzard had the following abilities: The micro circuitry of the costume is highly advanced and enables the wearer to freeze any moisture in the air around the wearer into unusually hard ice to form various projectiles and shields. It is capable of shooting small ice missiles or bullets with sufficient force and density to cut steel. The wearer can also make metal brittle by coming into direct contact with it. The wearer is effectively shielded from sub-zero temperatures the suit generates. It can also project enough cold to lower the temperature in a room from 68 to 32 degrees Fahrenheit in 30 seconds. However, the finite supply of water and moisture that the suit is able to take into its reserves is not sufficient to create giant ice bridges such as the mutant Iceman is capable of creating.

The current costume used by Donny Gill has been improved upon by the members of the Thunderbolts formerly known as the Beetle and the Fixer. It can essentially emulate most of the powers originally wielded by the mutant known as Iceman, including the spontaneous generation of Ice Bridges for extremely swift and maneuverable transportation (it does not give the wearer thermal vision). The limits of this costume are not yet known.

Aside from the costume none of the Blizzards had any permanent superhuman abilities. However, the first Blizzard was an accomplished engineer and a pioneer in the field of cryonics.
