"Worship me. Die for your crime of defying the House of One Hundred Demons, and repent in the afterlife. There are none before me, and will be none after me. I am the Demon King of the Sixth Heaven, Oda Nobunaga!" [Dramatic Cape Flourish]According to the Jesuit Father Luís Fróis, Oda Nobunaga called himself "Demon King of the Sixth Heaven" (dairokuten-maō), a title properly belonging to Māra, the Buddhist counterpart of Satan (though portrayed in mythology as a Noble Demon). While Nobunaga was most likely being sarcastic, and in any case he's not the only daimyō of the Sengoku Jidai whose ruthlessness has inspired a Historical Villain Upgrade, many popular depictions of Nobunaga literally demonize him, or at least give him supernatural powers. A subtrope of Historical Villain Upgrade. Compare We Didn't Start The Führer and Dracula (as Vlad Tepes).
Examples:Anime and Manga
- In Black Lion, Nobunaga is actually possessed by alien invaders who equip his armies with high-tech armaments so he can conquer Japan as a beachhead (probably; the backstory isn't covered much).
- In Samurai Deeper Kyo, Nobunaga was Japan's fiercest warlord who has a massive hate on for the main character. True to his nickname, his powers all revolve around Grim Reaper based attacks. Shou Hayami voices him here.
- In Wrath of the Ninja, Nobunaga appears to be the chief antagonist for the 3 heroes, conquering Japan with demonic help and seeking to be transformed into a demon himself. This time, however, there's a Man Behind the Man, a demon looking to use the bloodshed of war and Nobunaga's cruelty to power the demons themselves, and Nobunaga is just his patsy.
- In Blood Reign: Curse of the Yoma, Nobunaga doesn't directly appear, but the story takes place at the height of his conquests, and he influences the story since the main character is a ninja serving the Takeda clan when it opposes Nobunaga, and because the brutality of Nobunaga's conquests is giving power to the Yoma demons. At one point the main character thinks about Nobunaga's brutality and wonders if he is a demon. While he's doing this, Nobunaga and his army are seen in a montage, and all of them have glowing red eyes.
- In Ghost Sweeper Mikami, the vampire lord Nosferatu is actually Oda Nobunaga. Or if Father Karasu's theory is correct, Nosferatu murdered a young Nobunaga and stole his identity. Either way, Akechi Mitsuhide eventually discovered his master's demonic nature and that was the reason for his betrayal at Honno-ji.
- In the second Peacock King OVA, Castle of Illusion, a resurrected Nobunaga rebuilds Azuchi Castle as a fortress of evil and commands an unholy army of Cherubim.
- In Kamen Rider OOO's movie, the Kougami Foundation created a Homunculus copy of Nobunaga; since he was made from the same materials as the villainous Greeed, he ends up becoming a similar creature. However, this is revealed to be involuntary, instead acting as a Super-Powered Evil Side who comes forth to seek revenge on the descendants of those who killed the original Nobunaga.
- The Call of Cthulhu supplement Secrets of Japan reveals that Nobunaga is but one of Nyarlathotep's thousand masks, and that the Outer God still occasionally pulls him out for, of all things, business meetings.
- In MapleStory: Mark of Honor, Nobunaga's Evil Plan is to become the reincarnation of the Sixth Heaven Demon King.
- Double Subverted in Onimusha: Nobunaga starts out as human, gets an arrow through the throat, and is revived by demons to work for them—but winds up taking control of the demons who wanted him for a lackey! Incidentally, he pulls a One-Winged Angel twice in the second game, once in the third.
- In Persona 2 there are monsters/Persona based on Nobunaga called "Demon King", in Japanese, it's called "Dairoku Tenmaoh". Later, in Persona 4, Kanji Tatsumi's evolved Persona is a shortened version of these demon/Persona: "Rokuten Maoh".
- In Sengoku Basara Nobunaga is, once again, a cruel, ruthless S.O.B wielding a sword and shotgun combo and a nasty cape that can also attack enemies. It's also quite possibly the most Obviously Evil depiction of him ever: a Tin Tyrant decked out in Spikes of Villainy and often seen reclining on his throne of skulls. And when you have Norio Wakamoto as the voice actor, ham is, of course, to be expected.
- The anime turns this Up to Eleven: Dramatic Thunder and Ominous German Chanting accompany Nobunaga whenever he makes an appearance.
- And the third game (and The Movie of the anime) does even better when Nobunaga returns from Hell, having apparently taken over the sixth underworld and turned his epithet into a literal description. As a playable character, his story pretty much involves killing everyone else in Japan before returning to hell.
- Sakura Wars: So Long, My Love has Nobunaga as the Big Bad commanding The Legions of Hell.
