8 MORE Video Game Heroes Who Turned Evil In The Sequel
6. Siegfried Schtauffen - Soul Calibur
The Soul Edge, the weapon of legend. It was the desire of all the cast of the original title in the Soul Calibur series to wrest control of the weapon from Cervantes who was its current wielder at the time.
As the franchise has gone on and the lore around this sword has changed and grown, one thing has remained the same, it's power corrupts absolutely and can turn even the mightiest heroes into the greatest villains, and there is no better example of this than the sorry tale of Siegfried.
This warrior set out to find the sword only for it to take his very soul in the process. As the newly dubbed Nightmare, Siegfried was forced to commit atrocities as the weapon used his body like a puppet and became the primary antagonist of the series.
Eventually, he would be freed from the monsters control and set out to destroy the weapon once and for all, but for a time there was no one who didn't look upon his shadowy form in terror.
