It is notable that his concept bears similarities with Soulcalibur IV boss Algol. Despite being unused, Edgardo is still considered a canon character. He sought revenge against the Azure Knight for the death of his parents. However, he came to sympathize with Siegfried. Claiming to be an ally to Siegfried, he encountered and fought Taki prior to Soulcalibur IV. He was defeated, but spared.
