Dubhe Alpha Siegfried
He is said to be the strongest warrior among the God Warriors and the second in command after Hilda. He is very loyal to Hilda and seems to harbor deeper feelings for her. In the beginning, he does not believe the Saints when they tell him that Hilda is being controlled by the Niebelungen Ring. However, after Poseidon's Sea General Siren Sorento arrived and told the truth, he switched sides and sacrificed himself to kill Siren Sorento (although Sorento was thought to have died, he actually survived and returns to Poseidon). His armor resembles the dragon Fafner. He is commented to be "invulnerable", in the same way as the Norse legendary hero Siegfried, one of the reasons why he is considered the strongest God Warrior. He shared a common weakness with Shiryū, namely the exposure of the location of his heart, during an attack. It's a common weakness which all Saints (who bear a dragon in their cloth) share.
He appears in the anime adaptation only.
