The first son of Oda Nobuhide and thus, the next lord of Owari. His brash and carefree attitude caused his father and the clan's retainers to dislike him and nicknamed him "the fool". However, behind his chaotic nature, Nobunaga was a highly intelligent man with boundless ambition and great strength and courage to back it up.
Blood Knight: His grin when he does battles is wide and vicious.
Catch Phrase: "It was inevitable!" Reputedly the historical Nobunaga's final words.
The Chosen One: Only the Star Savior is supposed to be able to pilot the mecha he easily takes over. Joan also has visions of him. According to Joan, he can prevent a calamity from befalling both stars.
Expy: Of Takuto Tsunashi. Nobunaga's hair is basically a gray and black version of Takuto's Ginga Bishonen red and yellow hair style, neither are lacking in the "flair" department, and they share the same voice actor
I Hate Past Me: Has had nightmares of the real life Nobunaga since he was a kid, and he has hated and feared that he could be such a person since.
Idiot Hero: Subverted. It's obvious that Nobunaga is very shrewd. He quickly figures out how his friend figured out he was talking about a girl, and when he discovers an enemy raiding party he immediately reports it rather then charging in. However, he also does not care at all for social niceties, choosing to ditch his own brother's coming of age ceremony for hunting. Hence his nickname, "The Fool"
Improbable Aiming Skills: He manages to take our three mecha units using nothing but a bow and arrow by firing through the small openings in the heads that allow the pilots to see.
A young woman from the Western Planet who frequently dreamed of a woman being burned at stake and was ridiculed for it. When Leonardo da Vinci offered her a chance to find out what destiny has in store for her, Jeanne took a leap of faith and traveled with the genius inventor to Eastern Planet. There, she met Oda Nobunaga whom she reluctantly served under the guise of a man.
Historical Beauty Update: While the real Jeanne D'arc was indeed buxom, though probably not quite to Kaguya's extreme, she had short, black hair and wore male clothing, whereas Kaguya has long blonde hair, big blue eyes and skimpy clothes. Though she does wear male clothing later.
Ms. Fanservice: In her Western garb. Not so much when disguised as a man.
Paper-Thin Disguise: The first time Himiko meets Jeanne, she immediately opens her shirt to confirm her suspicion. And Caesar just needs one look at her from afar to know she's a woman. Even Ichihime seems to know that she is female.
Primal Fear: Of fire. Most likely caused by her connection to the actual Jeanne D'arc and possibly Mori Ranmaru.
Cynicism Catalyst: His dead little sister. Though in an odd version of this, while Hideyoshi does use her death as motivation, he doesn't use it in revenge against the people who indirectly caused her death: the Oda clan.
Instant Expert: He almost immediately figures out how to expertly control Da Vinci's tank.
Yamato Nadeshiko: To the core. She is a true daughter of a noble warlord, elegant and soft-spoken much of the time but revealing a keen insight and will of iron when necessary. She supports her clan without a second thought, accepting an Arranged Marriage by threatening to kill her betrothed if he crosses her clan. When the castle comes under siege, she prepares to defend the castle with Naginata in hands.
The Only One Allowed to Defeat You: Though it was too late for Kenshin to play the trope straight, states that he was supposed to be the one to defeat Shingen, and is disappointed that Nobunaga beat him to it.
Creepy Cool Crosses: He's surrounded by Christian themes and imagery, and clearly not the hero he presents himself as.
The Faceless: His face is obscured from view by an eerie light. He seems to be able to make himself appear as whatever his target wants to see, appearing as an Ambiguously Brown man to Alexander and a stunning beautiful woman to Caesar. Their reactions, weeping Tears of Joy and swearing undying loyalty, suggest this allows Arthur to influence them.
Innocent Blue Eyes: Appears to Caesar as a maiden with beautiful blue eyes and golden hair, while playing up the innocent image associated with them.
Arranged Marriage: He agrees to side with the Oda Clan, in exchange for Ichihime's hand in marriage. She accepts, threatening to kill him if he goes back on his word. He greatly admires this, and shows genuine efforts to earn her affection.
Big Damn Heroes: Rescues everyone from Hannibal and Charlemagne, blasting away their ice-cloud and turning the tide of battle.
Brainwashed and Crazy: After seeing King Arthur's "face", which appears to him as a stunningly beautiful woman. This causes him to act as Arthur's agents, summoning Arthur's castle to the eastern planet and declaring his intentions to help Arthur bring about a new world. He even tries to destroy the Oda clan, before being freed by Nobu.
Cool Mask: It covers half of his face. He tells Mitsu that it originally covered an injury from a duel, but he found women were so fascinated by it that he decided to keep it. It shatters when Nobu frees him from Arthur's mind control.
Eleventh Hour Superpower: Rare villainous example. When Nobunaga is about to defeat him in Episode 12 he manages in desperation to "become a Dragon", overloading his mech on the quantum energy of the leylines.
Et Tu, Brute?: Well, he is Caesar. The imps turn on him, killing him and Ichihime.
Badass: To the point where Hideyoshi, Jeanne and Nobunaga touting a total of 5 Regalia are literally no match to him. He is also casually mentioned to be able of conquering the Star of the West had it not been for King Arthur.
