歐貝利斯克的巨神兵（オベリスクの巨神兵 / Obelisk the Tormentor）是《遊戲王》系列中極具代表性的三幻神之一，與太陽神的翼神龍、歐西里斯的天空龍並列，擁有強大的戰鬥能力與特殊效果，象徵著無可匹敵的破壞力。在原作漫畫、動畫及遊戲卡牌中，歐貝利斯克的巨神兵以其威壓感十足的外觀、毀滅性的效果與獨特的召喚條件，成為許多《遊戲王》粉絲心中的經典卡片。

首次登場於原作漫畫《遊戲王》「決鬥都市篇」，是海馬瀨人所持有的幻神獸，在決鬥中展現出極強的支配力。其卡面以藍色巨人形象示人，肌肉發達，充滿戰神般的威嚴，並以雙臂交叉的姿態象徵無可撼動的力量。漫畫與動畫中的歐貝利斯克被賦予特殊的「神之力」，能夠無視許多規則，展現超越常規怪獸的壓倒性能力。

在官方發行的實體卡牌中，歐貝利斯克的巨神兵屬於「幻神獸族」，擁有4000攻擊力與4000防禦力，並且需要三體怪獸作為祭品才能召喚。作為三幻神之一，它具備無法被對手指定為效果對象的耐性，能夠抵擋許多針對性效果，提升場上的生存能力。最具代表性的效果是「神拳粉碎」，當解放場上的兩體怪獸作為祭品時，能夠一次性摧毀對手場上的所有怪獸，並給予對手4000點傷害，展現毀滅性的終結能力。然而，缺點是無法進行特殊召喚，且通常召喚時需要三體怪獸作為祭品，使其在實戰中較難運用，特別是在高速環境的比賽中，如何有效召喚並利用其效果成為一大挑戰。

相比其他幻神獸，歐貝利斯克的巨神兵強調純粹的戰鬥破壞力，擁有穩定的攻擊與抗性，不易受到效果干擾，使其在某些場合具有優勢。然而，缺乏自主保護機制，且不能像太陽神的翼神龍那樣靈活適應各種戰術，這使得它在競技環境中較少被採用。但對於喜愛三幻神的玩家來說，仍然是一張極具收藏價值與象徵意義的卡片，在某些特定構築中也能發揮強大的壓制力。

總體而言，歐貝利斯克的巨神兵作為《遊戲王》歷史上的傳奇卡片，無論是從故事背景、卡片設計，還是其戰術價值來看，都具有極高的地位。雖然在現代決鬥環境中受到召喚條件的限制，但其獨特的效果與強大的攻擊力，依然讓它成為許多玩家心目中的神話級存在。

Obelisk the Tormentor (オベリスクの巨神兵) is one of the three legendary Egyptian God Cards in the Yu-Gi-Oh! series, alongside The Winged Dragon of Ra and Slifer the Sky Dragon. Known for its immense battle prowess and unique effects, Obelisk symbolizes unparalleled destructive power. With its imposing appearance, devastating abilities, and distinct summoning requirements, it has become an iconic card among Yu-Gi-Oh! fans across the manga, anime, and trading card game.

Obelisk the Tormentor first appeared in the original Yu-Gi-Oh! manga during the "Battle City" arc as the Egyptian God Card owned by Seto Kaiba, demonstrating overwhelming dominance in duels. The card features a towering blue giant with a heavily muscular build, exuding the presence of a war god. Its signature pose, with arms crossed, symbolizes an unshakable and invincible force. In both the manga and anime, Obelisk is depicted as possessing a divine power that ignores many standard game rules, showcasing abilities far beyond those of ordinary monsters.

In the official Yu-Gi-Oh! trading card game, Obelisk the Tormentor belongs to the "Divine-Beast" type, boasting 4000 ATK and 4000 DEF. It requires three tributes to be Normal Summoned, reinforcing its status as a powerful yet demanding card. As one of the Egyptian Gods, it possesses built-in immunity from being targeted by opponent’s card effects, granting it strong resistance against removal or disruption. Its most iconic ability is Fist of Fate, which allows the player to tribute two monsters to destroy all monsters on the opponent’s field and inflict 4000 damage, making it a game-ending force. However, its biggest drawback is that it cannot be Special Summoned and relies on tribute summoning, making it difficult to use effectively in high-speed competitive formats. Mastering its summoning and timing is a major challenge for duelists.

Compared to the other Egyptian God Cards, Obelisk the Tormentor emphasizes pure battle power, offering stable attack strength and defensive resistance, making it less vulnerable to disruption. However, unlike The Winged Dragon of Ra, which has versatile adaptability, or Slifer the Sky Dragon, which scales with the player’s hand size, Obelisk lacks built-in protection mechanics and flexibility in strategy. As a result, it is rarely used in competitive play, but remains a highly valued card among collectors and fans. In certain deck builds, it can still serve as a powerful boss monster capable of turning the tide of a duel.

Overall, Obelisk the Tormentor stands as a legendary card in Yu-Gi-Oh! history. Whether in terms of lore, card design, or strategic impact, it holds an esteemed position in the franchise. While modern duel formats may limit its usability due to its summoning conditions, its unique abilities and formidable attack power ensure that it remains an iconic and mythical card in the hearts of many Yu-Gi-Oh! players.
