Ares (also known as "Palgaea") is the Greek God of War, who is trying to take Soul Edge to dethrone his father: Zeus. He commanded the Grand Priest of the Fygul Cestemus sect, Kunpaetku, to create a golem to help find him. Although Kunpaetku created Astaroth in hopes of taking Soul Edge for himself, he didn't know that Ares, to assure Astaroth's loyalty, implanted Keres, the Agent of Death, inside him.
- Bestowed Aeon Calcos with new powers and encouraged him to 'devour Holy Warriors'.
- Enemy of Hephaestus as of Soulcalibur V.
- In the God of War series, Ares is killed by Kratos in the first installment, who then goes on to take Ares' mantle as the Ancient Greek God of War. That doesn't influence the Soul series in any form, since Kratos' appearance is non-canon.
