Siegfried of Dubhe

Siegfried is a fairly tall man with pale skin, blue eyes, and light brown hair. Of slight build and broad shoulders, his face displays a dignified bearing.

Siegfried is incredibly loyal to Hilda, to the point that he refuses to accept that she is doing wrong, and even when he finally admits it, he still prefers to honor his promise to protect her no matter what, even if she is no longer the person he knew. He is governed by an unbreakable code of honor and unequivocal respect for his rivals. Despite being the most powerful God Warrior, he is not conceited, but he also does not allow others to take him for a fool, as demonstrated by his recognition of Alberich's intentions of conquest. Despite his adamant will to follow his mistress to the death, he ultimately recognizes the actions of Seiya and his group as true justice and decides to sacrifice his life to save Asgard, demonstrating his willingness to abandon everything for his people.

Before occupying that position, he lived in the Temple of Valhalla with Hagen, Freya and Hilda, being the latter's personal guard, whom he said he would protect and follow to Hell itself if necessary. He always had doubts about the Battle against the Sanctuary and Athena, since he noticed a great change in Hilda of Polaris's attitude, however, he was not willing to disobey her, due to the loyalty he owed her and the strong feelings he had towards her. Siegfried is chosen as God Warrior of Dubhe and represents the Alpha Star, within the Big Dipper. He receives his God Robe on a mountain in Asgard, since it was located inside it. His first appearance is when, along with Hilda and his companions, they appear before Saori and the Bronze Saints, where his Cosmos begins to rival Seiya's. He reappears in the Temple of Valhalla, near the Statue of Odin, being the only God Warrior left alive and the last obstacle to save Athena and Hilda from Polaris. Seiya is the first to arrive before him, but his attacks are useless, since Siegfried has inherited the immortality of the Legendary Hero, becoming immune to blows. After this, the God Warrior counterattacks with his Odin Sword and easily defeats Pegasus. The next to arrive are Ikki, Hyōga and Shun. The Phoenix is ​​​​who faces him in a small combat, showing his great power and speed, however, the superiority of the God Warrior is overwhelming and the Bronze Saint falls quickly defeated. Seeing the defeat of his brother, Shun tries to protect himself, along with Hyōga, but not even the iron defense of the Andromeda Chain, prevents them from being affected by Siegfried's Odin Sword, both falling defeated as well.

After his companions fall, Seiya is the one who rises again. Seeing the determination in his adversary, the God Warrior uses his most powerful technique against him, but Shaina intervenes and both take part of the impact, all this before the eyes of a newly arrived Shiryū. The last remaining Bronze Saint begins to fight, but his attacks are also nullified by Siegfried's barrier. Despite this, he manages to detect his adversary's weak point, which is similar to his own, as his left fist falls for a moment leaving his heart exposed. This weak point was the same as the Legendary Hero's, because after bathing his body with Fafnir's blood, a blade fell on his back, at the level of his heart, leaving that place unprotected, the same one where he was later attacked and killed. Considering his mission over, Shiryū falls seriously injured by the continuous attacks received, leaving Pegasus the responsibility of defeating Siegfried. Seeing the Dragon's efforts, Seiya rejoins and exchanges blows with the God Warrior, but despite being struck in the heart, he remains standing, while Pegasus falls wounded and exhausted. The Sanctuary's defeat seems certain, but thanks to the Cosmos of Athena and her friends, Seiya rises again and launches one last attack, surpassing Siegfried's and striking him hard in the heart. Everything seems to be over, but the arrival of Sorrento de Sirena, a Sea General of Poseidon, complicates things. After understanding that Hilda was manipulated by the God of the Seas, to provoke the Battle against the Sanctuary, a dying Siegfried plucks his own Odin's Sapphire to give it to Seiya, confident that he would achieve victory.

Even though he is weak, the God Warrior prepares to continue fighting, but not even rupturing his eardrums can drown out his enemy's melody. Finally, in a suicidal attack, he manages to catch Sorrento and rise towards the Alpha Star. They die together, saying goodbye to Hilda, Asgard, and ready to reunite with their fallen comrades. It would later be learned that their sacrifice was in vain, as General Marino managed to escape before they disappeared into space. Siegfried's death generated a great sense of guilt in his older brother since he believed that if he had been stronger he could have saved Hilda so Siegfried would not have had to fight, this feeling of guilt led Siegfried to hate Athena, the Saints, Poseidon, and the Gods of Olympus. During Sigmund's battle against Gemini Saga, Alpha's God Robe along with Siegfried's "spirit" appear, at one point Sigmund believes that Siegfried is helping him defeat the Gold Saint because the shoulder pad, forearm, right arm and wrist of Alpha's God Robe are attached to Grane's God Robe but contrary to what Sigmund believed what Siegfried was trying to tell him was to not fight this would lead to Sigmund surrendering to Saga.

•Odin Sword: Siegfried points his index finger at his opponent and draws a circle on the ground from a distance around the target. When he completes the circle, everything inside is thrown into the air, as a violent release of energy occurs within the circle or marked area. Sharp rock and debris fragments rise vertically from the ground, flying to attack and cause intense pressure on the enemy.
•Dragon Bravest Blizzard: Siegfried intensifies his cosmos, creating lightning around his body, then concentrates that power in his fists and launches a very strong blow with both arms, while a kind of snow blizzard surrounds him, in his aura two dragon heads appear that shoot out and hit the opponent.
