As I can tell, this is loosely based on Incredibles 2 and Sengoku Avengers by genesischant on DeviantArt. This is their word about the idea:
"I was wanting to do a new redesigned/translated set of comics characters for a while, and the new Avengers movie presented a great team to build from. It has the kind of big iconic characters that work best for these sort of reimaginings. Instead of the theatrical 'chambara' setting I used for my Justice League, I decided that the historically based, yet still legendary figures of the Sengoku era of Japanese history would be the inspiration.
Iron Man ('Tetsu-jin', literally 'Iron-man') was the first character I worked on, and the elaborate samurai armor was an obvious choice. The distinctive mask keeps him recognizable. I used a fancy way of writing 'tetsu', meaning 'iron', as part of the patterned fabric. The interest with foreign technologies such as firearms was borrowed from the life of Sengoku celebrity Oda Nobunaga. The firearms themselves are fictionalized, but based on real-world examples.
Next up was Thor, who begged to be remade as a native Japanese deity. I ended up using 'Raijin' as the basis, known through popular culture as 'Raiden'. The thunder and lightning theme was great, and I gave him a rain hat and proper wet weather 'geta' sandals to stay with that theme. The weapon was a fusion of Raijin's hammer-like drumsticks and the real-life 'meteor hammer', which is a Chinese weapon with a similar Japanese equivalent.
I knew that the Hulk would be fun, and that he would be 'oni'-themed. I decided he would be a sorcerer who used paper 'ofuda' to seal in the monster ('kaibutsu') inside himself. The paper talismans have heavily modified versions of the character meaning 'to seal away' written on them, and his torn clothing have a seal script version of 'oni' that I've always liked. I considered using the traditional oni studded metal club, but I went the way I did to emphasize the character's history of destruction. He uses the Buddhist rosary to control his emotions.
My Loki was easily found after choosing my Thor. Kagu-tsuchi is a fire god like Loki, and is similarly both Raijin's brother and also an enemy of the gods. I gave him deer horns to replace his helmet and to bring to mind the asian dragon he is often depicted as. The mirror is based on one of the Imperial Regalia, and is my version of the Tesseract. In this story, the Lords of Yomi (the underworld) have given Kagu-tsuchi his father's spear (here representing the movie's scepter) and sent him against the mortal world.
Captain America was a challenge, and my friends helped a lot. They suggested the umbrella as a round element to replace the shield (hand-held shields weren't used at the time), and they suggested the 'sickly child who becomes a swordmaster' storyline, which is a standard for several great martial artists of the era. I had to abandon the nationalistic angle of the Captain, because Japan didn't exist as a country until it was united during this era. In keeping with that, this character is called 'Taishou', or 'General'. This is a rank that would be in line with both the legendary figures of the age and also similar to the position that the Captain had in the modern US army.
The SHIELD characters were a bit too obvious to me from the get-go. The ninja angle was a must, and I ended up using the famous 'Iga-ryuu' and 'Koga-ryuu' as my historical inspiration. The 'Tate-ryuu' (literally Shield School) is a blend of the two, with the Iga's job of protecting the Shogun, and the Koga's more relaxed (?) hierarchy. I gave my Fury two animal companions (messenger pigeons were a common method of secret communication) to represent the movie's Coulson and Hill.
I'm sure that's all a little TL;DR, but I really enjoyed working on these. I'll probably do something else like this in a while, but not until I have another idea this interesting."
Iron Man is reimagined as 'Tetsu-jin'.
Tetsuya Suzaku was born into a rich and powerful merchant family (though they had bought their way into a samurai house some years back). The Suzaku family owned mining interests as well as a variety of businesses that utilized the resources those mines produced. Weapons and armor were of particular interest to the brilliant young heir to the family name, and he voraciously studied the latest designs and barbarian technologies.
The fame and fortune of the Suzaku name increased due to his early adoption of new techniques and innovations. His personality and lifestyle ballooned with success, and his wild behavior led to a rift in the Suzaku family. A bloody attempt by a family faction to kidnap Tetsuya and force him reveal his new gunpowder formula forced him to change his outlook. He escaped the mine he was held in by building a suit of armor and weapons from strange materials he found in the mine depths.
Now he fights for his own philosophy of justice with a razor keen wit and the latest advancements in arms and armor.
Captain America is reimagined as 'Taisho'.
Shin Raijou was a sickly child of a low-level samurai bureaucrat, and was confined to his bed for much of his early years. He might have lived out his life in anonymity if he hadn't been present for a martial arts demonstration by a master swordsman. The young boy was enthralled, and afterwards begged the swordsman to take him on as a pupil.
The master refused, but Raijou went to his house where he found employment as a servant. He performed household chores faithfully for two years before finally being accepted as the old master's only student. He studied diligently, and his innate martial talent was revealed. After teaching all he knew, the old man was killed as the result of anti-bakufu treachery.
Raijou would spend the next decade as a soldier in the long and bloody unification conflict, distinguishing himself time and again as a sword prodigy and tactical genius. After the final battle, he disappeared, leaving the battlefield behind. He spent several years in solitude but now he's found a new sort of battle, to protect the people of the land and the honor of Japan.
Raijou favors a peculiar style of fighting that incorporates a steel-reinforced parasol. It sometimes serves as a non-lethal alternative to a sword, and sometimes is used in tandem with a sword.
Thor is reimagined as 'Raijin'.
Born of Izanami and Izanagi, Raijin is a powerful god of storms and thunder. He was sent down to Earth in human guise to stop the destruction waged by his brother, Kagu-tsuchi, god of fire and devastation.
Raijin has godlike strength and durability, and he wields a whirling manriki (meteor hammer variant) to frightening effect. He is good-natured and kind to mortals, but quick to anger and exceedingly stubborn.
He searches the islands of Japan to put an end to his brother's plans to sow chaos in the human world.
The Hulk is reimagined as 'Kaibutsu'.
Nobu Tsubana was a promising young onmyouji in the court of a powerful lord. When news spread of a terrible demon making trouble in the land, Tsubana was among those dispatched to exorcise it. The encounter with the mighty oni went awry, proving too much for any of the sorcerers and priests to handle, and Tsubana was forced to seal the creature inside his own body as a last resort.
Now Tsubana lives as a wandering outcast, for the demon within him will wake if he does not constantly keep his emotions controlled. When the oni stirs within him, he loses his grasp on his sanity as his body and mind both grow more monstrous. He uses meditation and specially prepared seals to keep himself from transforming into a monster.
Now he travels the roads of Japan, applying his skills as an onmyouji where they are needed, and battling fearsome youkai and kami attracted by the strong spiritual presence of the slumbering demon. Needless to say, only a fool would provoke his ire.
Black Widow is reimagined as 'Kumo', while Hawkeye is reimagined as 'Takajyou'.
'Kumo' is the code-name for the deadly ninja spy, Natsuko Iruma. Iruma was raised from birth in a brutal shinobi clan. She was trained to be an expert kunoichi, willing to kill or die at command. She was eventually assigned to infiltrate the court of the Shogun to destroy the shogunate from the inside.
The man known as 'Takajyou' was born Kin Obata. Obata was an orphan from a remote region of Japan, raised by bandits. His archery skills are without equal, easily able to fire off several shots at great range with pinpoint accuracy. He was the leader of a small gang until the day he was defeated and recruited by the spymaster of the Tate-ryuu.
It was here that Iruma came to the attention of the mysterious leader of the shogun's secret guard. Impressed with her superb skills, Iruma was given the option of joining. Fighting years of conditioning, she agreed to join, in large part due to her budding relationship with a fellow recruit, Takajyou.
Both now work for the fearsome Tate-ryuu, living and fighting in the shadows.
Nick Fury is reimagined as 'Furukawa'.
The Tate-ryuu, a shadowy group that backs the current bakufu government. It operates at all levels of society, with agents infiltrating and monitoring everything from the criminal elements to the Shogun's own household. The head of this secret clan is an enigma himself, a man known to his subordinates and enemies as Furukawa.
Naoki Furukawa is a true spymaster, author of a thousand devilish schemes, the indestructible figure that controls the feared Tate-ryuu. He keeps and trains birds to deliver orders to his operatives throughout Japan. He is rarely seen without Hiruko, the pigeon he entrusts with the most important missives, and Kou, an owl he's trained to intercept rivals' messenger fowl.
Loki is reimagined as 'Kagami'.
The man known as Kagami is truly the god of fire, Kagu-tsuchi, youngest son of the gods Izanagi and Izanami. His birth was difficult and his mother died. In a blind rage his father struck off the child's head.
Being a divine personage, Kagu-tsuchi recovered. However, he thereafter held a burning grudge in his heart against his father and all of Creation. When the opportunity presented itself, he stole the sacred mirror and used its power to transmit himself to the mortal world. There he used tricks and godly magics to sow chaos, using the mocking pseudonym Lord Kagami (a name which means 'mirror', but is written as 'fire god').
The gods elected to send Kagu-tsuchi's older brother Raijin after him to put an end to his brother's plot of destruction. The two siblings are destined to clash in a battle between immortals that will rage across the islands of Japan.
Well, I added my own OC to this collection, she's a European whose full name is yet to be revealed and only known as "Oya", and I am also including one of her descendants in the part of the Avengers we all know and love, as the equivalent to Winston Deavor. Also...I'm incorporating the setting that Thor and Raijin were long-term friends, and Tetsujin and Taisho's love affair was something that could be considered really outrageous, because, hey, Ancient Japan. I hope you're OK with period-typical homophobia.
