During WWII Super Sabre 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 (Jim Hammond) 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.
Fletcher, Crimson Commando, and Stonewall returned to America. When they arrived home they were disturbed by the criminal acts of people who thought they were "above the law". Finally deciding to do something they came out of retirement and would kidnap criminals and hunt them for sport. Later they accidentally captured Storm and realized that she was not a criminal. Faced with this dilemma they decided to hunt down Storm in order to keep their whereabouts a secret. Storm was also captured with another prison while they were hunted. Priscilla Morrison, who was in fact their actual target. Chasing down Morrison and Storm, Super Sabre was almost decapitated by a trap Storm had set. Later, Morrison betrayed Storm, but before she could kill Storm the Commando was able to kill her. Storm and the Commando then fought in combat, which she won. After she won she demanded that Commando and Stonewall turn themselves in. Distraught because they thought Super Sabre was dead, they complied and turned themselves in.
Months later Valerie Cooper arranged for the release of the Commando and Stonewall if they joined Freedom Force. They reluctantly agreed. Super Sabre turned up alive and also joined the Freedom Force.
Super Sabre and Freedom Force later worked with the X-Men against a cosmic entity known as the Adversary, but their attempts to enforce the government policy, the Mutant Registration Act, later led to battles with X-Factor and the New Mutants. Following a mission to Muir Island which resulted in Stonewall's death at the hands of the Reavers. Later during a mission which involved Cable, Super Sabre was almost decapitated again.
During an unknown period of time Super Sabre fought alongside other speedsters such as Quicksilver, Whizzer, Speed Demon, Black Racer, Makkari, Fast-Forward, and the female Captain Marvel. The Runner pitted them against each other to find out who is the fastest being in the galaxy.
The Commando then led a mission to Kuwait which led to a fight with the Middle Eastern mercenaries called Desert Sword. The mission ended with Super Sabre dead and the Commando crippled. Following this disaster, Freedom Force was disbanded.
Years later Wolverine visited the afterlife and was attacked by several of his dead foes, among them Stonewall, Pyro, and Super Sabre. Wolverine began to fight the dead villains until Colossus appeared to help Wolverine defeat them.
Recently, Selene revived Super Sabre and his former teammate Stonewall using a mixture of magic and the alien techno-organic virus on the island of Genosha. Selene sent Super Sabre and Stonewall to attack the X-Men on their new island of Utopia. He was last seen fighting against Colossus.
