Edgardo is a fictional character that was meant to be introduced in Soulcalibur III, along with Tira, Setsuka and Zasalamel. Since his in-game model, but not his movelist, was completed, Edgardo never made it into the final game due to scheduling issues and the resulting time pressure. He did, however, appear in Soulcalibur: Broken Destiny, as a custom character in Quick Match mode.
Despite being unused, Edgardo is still considered a canon character.
Claiming to be an ally to Siegfried, he encountered and fought Taki prior to Soulcalibur IV. He was defeated, but spared.
