Nobunaga Oda (織田信長, Oda Nobunaga) is the main antagonist in the Onimusha series. After defeating Imagawa Yoshimoto in Okehazama, Nobunaga established himself as a powerful leader who campaigned to unify Japan during the Sengoku period. However, Nobunaga met an untimely death after the battle when he was killed by a stray arrow which pierced his throat. Although he was presumed dead, Nobunaga was resurrected by the demons, who had been drawn to his cruel ambition during his mortal life.
Onimusha: Warlords Edit
In Onimusha: Warlords, Nobunaga was set to be initiated by the Demon Lord Fortinbras, but this scheme was foiled by Samanosuke Akechi as he defeated Fortinbras with the power of the Oni. The exact details of Samanosuke and Nobunaga's stand-off is told by Samanosuke himself in Onimusha Blade Warriors.
Onimusha 2: Samurai's Destiny Edit
In Onimusha 2: Samurai's Destiny, Nobunaga had ascended to become the new Demon Lord and terrorized Japan with his army of genma. His merciless attack on the Yagyu village, evoked the vengeance of Jubei Yagyu who sought to destroy him and his evil ambition. Nobunaga exercised his power to force slaves to mine huge supplies of gold in order to build the extraordinary Golden Evil Statue. This demonic behemoth was imbued with Nobunaga's spirit and was intended to crush any resistance, until Jubei summoned his ultimate Oni power to destroy it, along with Nobunaga - who vowed to return.
Onimusha 3: Demon Siege Edit
Nobunaga's ominous words were true, as he returned in Onimusha 3: Demon Siege. This time he planned to use the temporal distortions created by his scientist Guildenstern to control the past, present and future. This plan was thwarted by the combined efforts of Samanosuke Akechi and Jacques Blanc, and after an intense battle Nobunaga was finally defeated at Honnoji Temple in 1582, with his spirit absorbed into the Oni Gauntlet.
