ナイトメア(ソウルキャリバー)
Main antagonist of the [[SoulCalibur|Soul]] series. He made his first appearance in [[Soul Edge]], with his proper debut being in SoulCalibur. With the [i]nom de guerre[/i] of the "Azure Knight," he is the host, wielder and living incarnation of the cursed sword, [[Soul Edge (weapon)|]].

Nightmare appears as a violent and ruthless creature covered in [[blue armor|dark blue armor]]. His prominent feature is his right arm, which has been twisted and transformed into large three-digit [[claws]] whose flesh overlaps his entire right arm and shoulder. He is depicted with Soul Edge in his [[left-handed|left hand]], symbolizing his polarity with [[siegfried schtauffen|Siegfried]]. Over the years, his appearance has progressively grown more and more demonic, as influenced by the state of Soul Edge itself. When unable to take possession of a corporeal body, Soul Edge can form Nightmare as a sentient suit of armor, though this is a desperation tactic.
