Martin Fletcher was born in Massachusetts. During World War II, as Super Sabre he fought against the Axis powers which dominated Europe. He fought alongside three other heroes during this time: Stonewall, Crimson Commando, and Yankee Clipper. Following the war Super Sabre along with the Commando and Stonewall continued to fight crime. They even hoped to join the Human Torch in fighting communists, but government officials were concerned that the over enthusiastic heroes would cause a real war. The government requested that the trio retired, which they reluctantly did.
