The Super Sabre's origin was never established; his powers were mutant in origin. Super Sabre was active during World War Two with the Crimson Commando, Stonewall, and the Yankee Clipper (I). The quartet were active during World War Two, although it is not known if they teamed up any of the other heroes of the time or with groups like the Liberty Legion or the Invaders.
After the war the Commando, along with Stonewall and Super Sabre, returned to Massachusetts and began fighting crime, the Yankee Clipper (I) apparently having died during the war. In the early 1950s the trio offered their services to the American government in the fight against Communism, but the government declined their offer (for unspecified reasons) and instead persuaded the group to retire from active crimefighting.
Some time after that--perhaps a few years, perhaps a few decades, it was never made clear--the trio, disgusted with modern society, began capturing and playing "The Most Dangerous Game" with criminals and those they disapproved of. They came in conflict with and were defeated by Storm and the X-Men. Eventually the trio joined joined the government-sponsored group Freedom Force. During the Gulf War Super Sabre was killed by an Iraqi metahuman.
Super Sabre had superspeed and could create mini-sonic-booms by snapping his fingers. It was established that Super Sabre had a son who fought in the Vietnam War, though it is unknown whether the son had any superpowers.
Note: The Super-Sabre was a Korean War-era fighter plane. We're supposed to see the name "Super-Sabre" and associate it with speed and power. However, there's no good reason why a World War Two speedster would name himself after a plane that hasn't been invented yet. The only alternative explanation for this is that the Super-Sabre (whose civilian name was never given) had another superhero sobriquet during World War Two, or that Chris Claremont screwed up.
