《聖鬥士星矢》北歐篇是動畫原創劇情中最具史詩感的章節之一，描繪五小強與奧丁神之地──亞斯格特的神鬥士之間的宿命對決。這些神鬥士不僅造型華麗，戰力也堪比黃金聖鬥士，他們的戰鬥不只是力量的碰撞，更是忠誠、悲傷與信念的試煉。以下是對七位神鬥士的實力排序、技能解析以及他們的最終命運的全盤剖析。

在這場寒冰與榮耀交織的戰場上，最強者無疑是天樞星(Duhbe Alpha)雙頭龍齊格弗里德(Siegfried)，他作為希路達麾下的第一神鬥士，不僅氣場逼人，戰力也足以匹敵撒加等黃金聖鬥士中的頂級存在。他的必殺技「奧丁神劍」(Odin Sword)能斬開星辰，「狂風暴雪雙龍拳」(Dragon Blizzard)則釋放出接近絕對零度的寒氣。然而，在與紫龍的死戰中，他最終選擇收手，決定與海魔女蘇蘭特同歸於盡。因對希路達的忠誠和內心的覺醒而犧牲，成為最具悲劇色彩的角色。

緊隨其後的是操控冰火雙屬性的天璇星(Merak Beta)——八足馬哈根(Beta Merak Hagen)，他那足以凍結火焰的「宇宙凍結」(Universe Freezing)與燃燒一切的「烈焰拳」(Great Ardent Pressure)展現出極致對比的戰鬥風格。然而，冰河以極光處刑破解其攻勢，並藉由芙蕾雅的情感牽絆，讓哈根心神動搖，最終敗下陣來。

排名第三的天璣星(Phecda Gamma)巨蟒德爾魯/索爾（Thor）是典型的力量型戰士，他雙持雷神之鎚，力大無窮，其招式「ミョルニルハンマーによる攻撃」(Hammer)能震裂大地。必殺技泰坦巨風(Titanic Hercules)儘管力量驚人，但他動作略顯遲緩，成為星矢天馬彗星拳的破綻所在，最終因速度與策略的劣勢落敗。

天權星(Megrez Delta) 紫水晶 阿魯貝利西(Alberich)則是神鬥士中最具謀略的一位。他擅長自然操控，能以「精靈魔拳」(Nature Unity)喚起植物與冰霜形成陷阱，並以「紫水晶之盾」(Amethyst Shield)困住對手。然而，他的詭計與野心最終被紫龍識破，摧毀他的防禦，也揭示他自私冷酷的本性。

野性十足的玉衡星(Alioth Epsilon)法庫達/芬里爾（Fenrir）以狼群戰法著稱，動作敏捷，招式如「極地凶狼爪」(Wolf Cruelty Claw)與召喚「北極狼群」讓對手難以應對。但在一輝的幻魔拳面前，他的精神防線被撕裂，最終敗於「鳳翼天翔」的全面攻擊。

音波系的神鬥士瑤光星(Alkaid Eta)米伊美(Meem)擅長用琴音作戰，其「死亡交響曲」與「豎琴光速拳」(Harp speed light)讓瞬一度陷入苦戰。然而，面對一輝跟瞬的星雲風暴的正面對決，他的音波終究被粉碎，而其內心對養父捷克弗里德的愧疚與悲傷也使他在戰鬥中喪失戰意，選擇放棄。

至於神秘的影子神鬥士巴度(Bud)，作為開陽星(Mizar Dzeta)希度(Syd)的影子兄弟，他專精暗殺與突襲，能以「影子維京虎吼拳」(Shadow Viking Tiger Claw)隱身偷襲。然而，他的心中懷著對弟弟的矛盾情感，當星矢與冰河聯手進攻時，他終因情感糾葛而敗下陣來，成為最具人性掙扎的一位神鬥士。

隨著七位神鬥士陸續敗北，北歐篇也迎來高潮。原來希路達女王早已被海皇波塞冬操控，才會與聖鬥士為敵。最終，星矢穿上奧丁神袍，舉起永恆之槍貫穿詛咒結界，使希路達重獲清明。這場寒冰下的信仰之戰，終以五小強的勝利和神鬥士的救贖收場。

雖然北歐篇非原著劇情，但其情節悲壯、人物立體，加上寒冰系招式的視覺張力，使其成為《聖鬥士星矢》動畫中最令人難忘的篇章之一。神鬥士們並非純粹的反派，而是背負信仰與忠誠的戰士，每一位的倒下，都是一段北歐神話的終章。

The Asgard Arc of Saint Seiya is one of the most epic original storylines in the anime adaptation. It depicts a fateful showdown between the five Bronze Saints and the God Warriors of Asgard, the land ruled by Odin. These God Warriors not only possess stunning designs but also have powers that rival those of the Gold Saints. Their battles are more than mere clashes of strength—they are trials of loyalty, sorrow, and conviction. The following is a comprehensive analysis of the seven God Warriors, including their power rankings, signature abilities, and ultimate fates.

On this battlefield of ice and honor, the strongest warrior is undoubtedly Dubhe Alpha Siegfried, the Twin-Headed Dragon. As the leading God Warrior under Hilda, he radiates overwhelming presence and power comparable to the top-tier Gold Saints, such as Saga. His ultimate technique, the Odin Sword, can slash through the stars, while Dragon Blizzard releases cold approaching absolute zero. In his final duel with Shiryu, Siegfried chooses to retreat from the fight and sacrifices himself by perishing alongside the Sea Sorceress Sorrento. Driven by his loyalty to Hilda and a newfound inner awakening, he becomes the arc's most tragic figure.

Next in power is Merak Beta Hagen, the God Warrior of Fire and Ice. His signature moves include Universe Freezing, capable of freezing flames, and Great Ardent Pressure, which burns all in its path. These dual attributes create a striking contrast in battle. However, Hyoga ultimately overcomes him using Aurora Execution, and through Freya’s emotional appeal, Hagen’s resolve wavers, leading to his defeat.

Ranked third is Phecda Gamma Thor, the giant serpent wielder of dual Mjölnir hammers. A classic powerhouse, his mighty attack Titanic Hercules shakes the earth itself. Yet, his slower movements become a fatal flaw, allowing Seiya’s Pegasus Comet Fist to exploit his lack of speed and strategy, resulting in his fall.

Megrez Delta Alberich, the Amethyst warrior, stands out as the most cunning among the God Warriors. He commands nature with Nature Unity, summoning plants and frost to trap opponents, while his Amethyst Shield ensnares enemies in crystal. But his treacherous schemes and ambition are ultimately exposed and destroyed by Shiryu, revealing his selfish and cold-hearted nature.

Alioth Epsilon Fenrir, a wild and feral fighter, fights with the aid of arctic wolves. His attacks, such as Wolf Cruelty Claw and the summoning of Northern Wolves, are fast and relentless. However, against Ikki’s Phantom Demon Fist, Fenrir’s mental defenses collapse, and he is overwhelmed by the Phoenix's Wings Rise in a full assault.

Alkaid Eta Mime, the sonic warrior, uses his harp as a weapon. His Death Symphony and Harp Speed Light once corner Shun in battle. Yet, when confronted by both Ikki and Shun, Mime’s sonic waves are shattered by Nebula Storm. His inner conflict and guilt over his foster father Siegfried cause him to lose his will to fight, leading to his surrender.

Finally, the mysterious Bud, the shadow God Warrior of Mizar Zeta Syd, specializes in stealth and assassination. His Shadow Viking Tiger Claw allows him to strike from the shadows. However, his conflicted emotions toward his brother Syd weaken his resolve. When Seiya and Hyoga combine forces, Bud is ultimately defeated, standing as the God Warrior with the most visible human struggle.

As each of the seven God Warriors falls, the Asgard Arc reaches its climax. It is revealed that Queen Hilda was under Poseidon's control, which explains her hostility toward the Saints. Ultimately, Seiya dons the Odin Robe and wields the Eternal Spear to pierce the cursed barrier, restoring Hilda’s sanity. This battle of faith beneath the ice ends with the victory of the Bronze Saints and the redemption of the God Warriors.

Although the Asgard Arc is not part of the original manga, its tragic narrative, well-developed characters, and visually striking ice-based techniques make it one of the most memorable arcs in the Saint Seiya anime. The God Warriors are not merely villains; they are warriors bound by loyalty and faith, each of their defeats marking the end of a Nordic legend.
