The first Sabre was a former knife thrower named Paul Richarde until he was selected by Modred to oppose Black Knight. Paul Richarde was given an armor, an animated gargoyle. and Mordred's Ebony Dagger (the weapon with which Mordred had killed the first Black Knight). He was defeated by Black Knight after his horse Aragorn kicked the dagger from Le Sabre's hand.
The second Sabre is a mutant super villain. His first appearance was in X-Men #106. Young and reckless, Sabre was chosen by Mystique to join her new Brotherhood of Mutants, though never actually participated in any missions. He had the mutant ability of super speed, and took the name of the deceased Super Sabre. It is unknown if he continues to serve Mystique behind the scenes, or if he even retains his powers after Decimation. Hyper-accelerated metabolism augments his natural speed, reflexes, coordination, endurance, and the healing properties of his body.
The miniatures game Striker is a science fiction tactical wargame that was published by Game Designers' Workshop in 1981 as a boxed expansion to the Traveller role-playing game. It was notable for attempting to cover a broad range of technological levels and having an intricate "engineering" style of vehicle design by the player using formulas and tables. The combat rules were an elaboration on the rules introduced in the Azhanti High Lightning game, using a 2D6 mechanic very different from the original "Traveller" rules. A later game, Striker II, was based on the systems in GDW's Command Decision WWII rules and tied to the role-playing game Traveller: The New Era.
