Although a much rarer version of this exists for SNES, it has little in common with its Mega Drive counterpart and is more of port of the unlicensed. Siegfried, who made his debut in the original Soul Edge and has been a series mainstay ever since, is a German knight whose mind was lost when he mistakenly. Over the course of history, the Soul Calibur, passed on through generations by the guardians of the sword, has been used to shatter the Soul Edge and the subsequent blades created from its fragments. Soul Edge VS Samurai Spirits is an unlicensed fighting game released on the Sega Mega Drive as a follow up to both Soul Calibur and Samurai Spirits II.It was presumably developed by the same company as they use the same exact fighting engine. By forging the Soul Calibur, and trapping his own soul within the blade, Algol created the one holy blade powerful enough to destroy the Soul Edge. Algol then knew that the Soul Edge had to be destroyed.

Possessed by the power of the Soul Edge, Algol's son attacked the Hero King who, with great pain and reluctance, was forced to kill the young man. The man who succeeded in this was Algol's own son. This man, Algol, sought to use the sword to bring about peace to the world, and was heralded as the 'Hero King.' Unfortunately, the draw of the Soul Edge attracted several men to attempt to steal the blade. Only one man was able to wield the evil sword Soul Edge without becoming tainted by it. However, after years of bloodshed, the sword evolved into a powerful instrument of evil, tainting all those who grasped its power with an overwhelming urge to conquer and destroy. The Soul Calibur was created in order to destroy the evil blade Soul Edge, a weapon originally forged to be an ordinary blade.
