Abilities: The Black Knight was a master of swordsmanship, of horseback riding, and of all forms of combat known in Britain at the time of Camelot.
Weapons: The Ebony Blade, forged from a meteorite by Merlin, possesses a number of unusual properties, some innate to the metal, and others due to magical enchantments. The sword is extraordinarily hard and invulnerable to all harm. Weighing fifty pounds, the sword is capable of cleaving through any substance up to foot-thick steel, with the probable exception of Adamantium. Its mystical properties include an immunity to magic. The sword can deflect mystical energy and shatter mystical barriers and shields. When angled in a certain way, the Ebony Blade will absorb energy. It is not known whether this latter capability of the sword is due to a physical property of the blade's metal or to an enchantment. For unknown reasons contact with the Ebony Blade once caused the Grey Gargoyle to change back from his stone-like form into his normal human one.
Merlin created a magical bond between the sword and its prime wielder (the original Black Knight and his successor) enabling that wielder, through arcane means, to transport himself magically to the sword or the sword magically to himself should the sword be separated from its wielder.
Merlin also placed an enchantment on the Ebony Blade such that the wielder of the sword could not be killed (although he could be injured) while he carried it, except by a weapon made from the same meteor as the Ebony Blade.
Due to the mystical bond that Merlin created between the Ebony Blade and its prime wielder, "evil" acts of bloodshed committed with the sword by its wielder with mystically taint the sword. The Ebony Blade will then mystically induce its wielder to commit further acts of bloodshed. The present wielder of the Ebony Blade, Dane Whitman, the Twentieth Century's Black Knight, purged the Ebony Blade of evil by plunging it into the enchanted Brazier of Truth, but should Whitman use the sword for "evil" ends, its malevolent influence will begin and start to grow once more.
