During his years working for Hammer Industries as a hired goon, Donald Gill had a troubled conscience. He had access to the powerful 'Blizzard Battlesuit', which could create blasts of intense cold, walls of ice, and other chilling effects, but he did not want to be used as a cog in a life of crime. He wanted to belong to a team and help those around him. He had been given opportunities to reform in the past, including a brief run with The Thunderbolts, but it was a recent encounter with Chase Stein which created the possibility of working with S.H.I.E.L.D.
