Dubhe Alpha Sigfried (アルファ星ドゥベのジークフリート, Arufa-sei Duube no Jīkufurīto) is one of the seven God Warriors of Asgard. He serves as an antagonist during the Asgard Arc.
The Invicible Warrior
Siegfried is said to be the reincarnation of the legendary hero Siegfried, a famous warrior and grandson of Odin, who battled and defeated the dragon Fafnir. However, he fell victim to a cursed ring found among Fafnir's treasures, which ultimately lead to his death at the hands of the Valkyrie Brynhildr, whom he became betrothed to and later was manipulated into betraying. Angered by his infidelity and unaware that he had been influenced by others, Brynhildr convinced Siegfried's brother-in-law to murder him.
Reborn in the present time, Siegfried had met Hilda, the priestess of Odin, long before becoming a God Warrior. Although life was hard, Hilda ruled Asgard with kindness and benevolence, and prayed that war never come to Asgard. Siegfried loved Hilda secretly in his heart, and vowed to protect her with his life.
When the time for the return of the legendary God Warriors has come, Siegfried and his best friend Merak Beta Hägen were chosen to become God Warriors. However, he noticed that Hilda had changed, becoming more aggressive and power hungry soon after. He was additionally warned by Freya that a drastic change had come over the priestess of Asgard. Siegfried didn't belive Freya and, despite Hilda's altered personality, he remained loyal to her.
The Last Defender Of Asgard
After the six other God Warriors were defeated, Siegfried was the last opponent for Seiya in front of the statue of Odin. Siegfried stated that he is impressed as fighting continued despite being repeatedly damaged. Seiya tells Hilda that she was under control of the Nibelung ring, but Siegfried does not believe it, and considers his words are absurd. Seiya attacks him with Ryu Sei Ken, but Siegfried refuses Seiya's attack as if his body was protected by an invisible shield. He then uses his sword of Odin attack to knock Seiya.
Phoenix Ikki, Andromeda Shun and Cygnus Hyoga came to the statue of Odin, and were shocked to see that Seiya had been defeated. Ikki challenges Siegfried to fight, but what dominates Siegfried easily with his speed and strength, defeating similarly. Then turns to avoid Shun and Hyoga, both wounded from previous battles, and Odin uses his sword against them, leaving the four bronze saints fallen.
To his surprise, Seiya gets up and tries to fight him again. Siegfried then prepares for his attack "Blizzard Dragon" against Seiya, but Shaina, arriving with Shiryu in time, jumping to protect this attack. Despite this, both were "defeated" by Siegfried technique.
Shiryu, seeing as this is the last standing bronze saint, so Siegfried faces in battle. However, all his attacks, including his Rozan Sho Ryu Ha, were rejected by the barrier created by the cosmos of Siegfried. Shiryu then realizes that the only way to defeat Siegfried was to use its Rozan Kou Ryu ha to this God Warrior. However, the spirit of Shura warns, saying that using this technique would result in the death of both, and the destruction of the last sapphire Odin. Detecting Shiryu's doubt to use his suicide attack, Siegfried is released, and attacks him with your most powerful attack: Blizzard Dragon.
Shiryu realizes the weakness of Siegfried and attacks him with the most powerful technique Rozan Ryu Ko and gets hit in the heart which causes weakening and then Siegfried tells Seiya Shiryu on Invincible Warrior and legend Also on his weak point before falling unconscious.
Siegfried does not die at that time since shortly after Siren Sorrento appeared, one of the Poseidon's marine general, and tells how as Polaris Hilda was changed by the Nibelungen Ring. Siegfried, full of anger, faces Sorrento and tries to kill him in the same way Dragon Shiryu did with Capricorn Shura. However, Sorrento escapes and survived the attack, but not Siegfried, who died in the process.
Sword of Odin (オーディーン・ソード, Ōdīn sōdo, "Odin Sword"): Siegfried energize his Cosmo concentrating it in his hand and using the index finger to direct the attack, which is not direct. The coup in the soil generates a circle around his opponent, creating a wall of cosmic forces, preventing their movement and a possible escape from the opponent. Within the circle a column of raw energy reaches its opponent from the bottom up, with sharp rocks and debris, devidamentes energized, releasing it to the sky and smashing his armor and body. The more strategic strike warrior Siegfried.
Dragon Bravest Blizzard (ドラゴン・ブレーヴェスト・ブリザード, Doragon Burēvesuto Burizādo, "Dragon Bravest Blizzard"): The most powerful blow of the God Warrior. Siegfried concentrates all his power in his fists surrounded by powerful lightning, then shoots two huge balls of energy that are powerful winds, triggered by his fists. When Siegfried launches the attack, it creates a sort of capsule formed by the high winds made the cosmos and the energy of the Warrior God that immobilizes his opponent. Further, the sealable take the form of heads of dragons, clashing against the enemy, and destroying it completely.
- As stated prior, Siegfried's character is based on the tragic hero of Richard Wagner's Ring cycle. In the original Norse myth, his character is named Sigurd; Siegfried had originally been the name of Sigurd's father.
- Siegfried's Cloth is meant to resemble the dragon Fafnir, a former dwarf prince who fell victim to the Nibelung Ring's influence, and who was slain by the hero.
