In the home version of Soul Edge (Soul Blade), an extra character named "Siegfried!" was added as an unlockable character. "Siegfried!" was an alternate version of the normal Siegfried taken from his no-input ending, where he was consumed by Soul Edge. This early version was very different from the former Nightmare, having crimson-red armor and a more flesh-like design, almost like if he was part of Soul Edge itself. He has no story nor ending, and only used Siegfried's Soul Edge without effects.
