The METABARON

Nameless (a.k.a. No Name), son of Aghora, is the last of a dynasty of perfect warriors known as the Metabarons.
Every Metabaron is handicapped by his father so that his endurance to pain is tested. He receives a powerful mechanical body part as a replacement for the destroyed limb, making every Metabaron a cyborg (in Nameless is the right ear and part of the brain).
In each generation, the son and heir must eventually face his father in a battle to the death. These battles have taken many forms, from hand-to-hand combat to dogfighting space duels. The rite of succession is only achieved once the cursed son succeeds in killing his father.
Bushitaka is the strict code of honor followed by the Metabarons (profoundly influenced by the Japanese Bushido). It demands that the practitioner dedicate themselves to victory in all things at any cost. Compromise is never an option, and the only alternative to victory is death. Bushitaka demands that the practitioner stifle all emotion, even to the point of sacrificing their own family members in the pursuit of total victory.
Each Metabaron draws upon an array of advanced weaponry known as the Metabaronic Weapons. These also includes cybernetically-implanted lasers, nanotech nuclear warheads implanted in the body, swords which can disintegrate in bursts of flame, and advanced spaceships.
Many of the Metabarons also exhibit powerful psychic abilities.
