《孔雀王》系列不論在漫畫或動畫中，其最終結局都以光明與黑暗的融合為核心，呈現出一種超越善惡對立的哲學思考。故事圍繞主角孔雀與其姊姊朋子（天蛇王），經歷數萬年的輪迴與磨難後，再度重逢並最終融合於涅槃之中，象徵世間並無絕對的善或惡，而是光與暗的相互依存與平衡，也為新的神話篇章奠定基礎。

在漫畫正傳的最終部份，孔雀與天蛇王在金剛曼陀羅展開最終決戰。這場戰鬥不僅是力量的比拼，也是理念的交鋒，阿修羅等角色此時組成「金剛界四印會」，共同見證光明與黑暗的最終交融。孔雀以智拳印的力量促使朋子進入涅槃，兩人在母體中最終融合，化為虛無，象徵光明與黑暗的徹底消融與統一。這個結局強調，故事並非簡單地由一方消滅另一方，而是任何存在中皆包含光影，真正的平衡源於彼此的共存。

結局也帶來新篇章的象徵意義。孔雀與朋子歸於虛無後，世界迎來新的開始。天空中的孔雀羽毛化作光芒灑向大地，象徵新的神話誕生，延續系列的神秘色彩與哲學深度。漫畫家荻野真在病中堅持完成《孔雀王戰國轉生》的最終章，透過生命創作出這個關於光明與黑暗共存的宏大結局，彰顯作者對於系列精神的執著與敬意。

在動畫與電影方面，《真孔雀王》動畫電影忠實呈現漫畫的宏大結局，將光與暗融合的主題以視覺化方式展現。相較之下，早期電影版本（由阿部寬主演）多改編自漫畫初期故事，劇情與最終結局存在較大差異，未能完整呈現光明與黑暗合一的哲學意涵。整體而言，《孔雀王》的最終結局不僅是故事的收束，更是一種思想的升華，透過角色的輪迴與融合，傳達出光明與黑暗、善與惡共生的深刻主題。

The conclusion of the Peacock King series, both in manga and anime, centers on the fusion of light and darkness, presenting a philosophical reflection that transcends the simple dichotomy of good and evil. The story follows the protagonist, Kujaku, and his sister Ponko (the Heavenly Serpent King), who, after tens of thousands of years of reincarnation and trials, reunite and ultimately merge in nirvana. This symbolizes that in the world, there is no absolute good or evil; rather, light and dark coexist and balance one another, paving the way for a new mythological chapter.

In the final part of the manga’s main story, Kujaku and the Heavenly Serpent King engage in their ultimate battle within the Diamond Mandala. This confrontation is not merely a clash of strength but also a confrontation of ideals. At this moment, characters like Ashura form the “Diamond Realm Four Seals” and witness the ultimate convergence of light and darkness. Kujaku uses the power of the Wisdom Fist Seal to guide Ponko into nirvana, and the two ultimately merge within the cosmic womb, dissolving into nothingness. This represents the complete integration and unity of light and dark. The ending emphasizes that one side does not simply annihilate the other; rather, every existence contains both light and shadow, and true balance arises from their coexistence.

The ending also carries symbolic significance for a new chapter. After Kujaku and Ponko merge into nothingness, the world experiences a new beginning. Peacock feathers scattered across the sky transform into light, signifying the birth of a new myth and continuing the series’ mysterious and philosophical depth. The manga’s creator, Makoto Ogino, completed the final chapter of Peacock King: Sengoku Reincarnation despite being ill, using his life to craft this grand finale that emphasizes the coexistence of light and darkness, showcasing his dedication and respect for the spirit of the series.

In terms of animation and film, the True Peacock King anime faithfully presents the manga’s grand conclusion, visually portraying the theme of the fusion of light and darkness. In contrast, earlier live-action films starring Hiroshi Abe were mostly adaptations of the early manga stories and differed significantly from the final conclusion, failing to fully convey the philosophical meaning of the union of light and dark. Overall, the ending of Peacock King is not merely the conclusion of a story but an elevation of thought, communicating the profound theme of coexistence between light and dark, good and evil, through the cycles and fusion of its characters.
