<p> Arthur's massive Zweihänder weapon, Deathcalibur is used by the Black Knight not only for conventional combat, but also as a means of summoning the Knights of the Underworld to the Grand Kingdom. The sword focuses many of the King's attacks during the Faraway Avalon battle. Despite its name, Deathcalibur is not a component of Excalibur nor one of the Sacred Swords. It appears to be as illusory as Arthur himself, dissolving to black mist along with the King after Sonic slays him. </p>
