Louis Sadler was a Canadian soldier who at some unrevealed point in time was given superpowers--superstrength, limited invulnerability, and perhaps others--by a so-far-unrevealed process. He used these powers during World War Two as Canada's foremost superhero during the war. After the war he went underground in his crimefighting, revealing his identity in 1963 and retiring to raise his son. When his son died of AIDS, Sadler went into a depression, but after a conflict with Alpha Flight and Northstar he recovered from his depression and rage.
