One great 'Shadow Monarch Fanfiction' is 'The Ascent of the Shadow Monarch'. It has a really engaging plot that follows the main character's journey in a very detailed way.
You can start by looking on fanfiction websites like Archive of Our Own (AO3). It has a large collection of 'Shadow Monarch Fanfiction' with different ratings and tags to help you find what you're looking for.
It could be an original character. For example, a young orphan ninja who has always felt like an outcast in the village. Discovering the Shadow Monarch powers gives them a new sense of purpose and a chance to prove themselves.
One idea could be a crossover where the Shadow Monarch's powers are introduced into the Naruto world during a major conflict, like the Fourth Great Ninja War. The main character, perhaps a young ninja, discovers the power of the Shadow Monarch and has to learn to control it while also dealing with the existing political and power struggles in the ninja villages.
The characters in the movie included the supporting role of Qin Shi, the female protagonist, and the supporting role of Brother Shadow. The male lead was Zhang Yun, the one-punch priest, the female lead was Yggdrasil. I really, really like Lord Shadow, and the female lead was Aunty. It was a bloody profit!
"Shadow Dislikes Me for Being Weak, Overnight Class Change to Shadow Lord" Author: Sea of Heart Sea Sea, is a game/game novel with summoning flow, Priest, and relaxing elements. It's finished and can be enjoyed without worry.
[User recommendation: This is an era where professionals are the main players.]
The poor relied on mutation (god-level talent), while the rich relied on technology (rare props).
Zhang Yun, who had nothing, planned to lie flat and choose a nanny profession to wait for death.
Who knew that his shadow was unhappy.
[Your shadow thinks you're weak, so it changed its class to Shadow Lord overnight!]
[Your shadow has used the skill "Shadow Gate" and pulled you into the "Shadow Plane". It has begun to recall historical events and search for a suitable hero's soul!]
[You have contracted the Hero's Soul and obtained the Shadow Hero-Full Moon Queen. Renara (S+)!]
[Your shadow has killed the Dungeon Boss "Rock Lizard Dragon Whelp". The opponent's shadow has been extracted and transformed into a Shadow Soldier. You have been summoned "Shadow." The authority of the Rock Lizard Whelp!]
[Your shadow has sent over the Dungeon Clear Reward…]
Just like that, relying on Big Brother Shadow, who was carrying his luggage, Zhang Yun, who was a nanny, was even more exhausted.
Why would he work hard if he could win lying down?
Until…
He realized.
These historical events and the huge threat hidden in reality…
I hope you will like this book.
Some fanfictions might have a plotline where the shadow monarch powers are linked to an ancient magic in the Harry Potter world. Maybe it was a power that was once known but lost, and now it's resurfacing through the main character. This could lead to a search for the origin of these powers, uncovering long - forgotten secrets of the wizarding world and changing the power dynamics between the good and the bad in the fight against Voldemort.
Harry Potter himself is often a popular character in these fanfictions. Since he's the main character in the original series, it's easy to incorporate him into the shadow monarch concept. Another popular one could be Hermione. Her intelligence could be combined with shadow monarch powers in really interesting ways in fanfiction.
😋I recommend "I'm Pregnant with the Prince Regent's Baby". This is an ancient romance novel. In order to survive, the female protagonist, Ian, decided to hug the male protagonist's thigh. In the end, after rebirth, he found out that the male protagonist was a female supporting character. The male protagonist's true love, the female protagonist, had also been reborn. However, the female protagonist still decided to cling to the male protagonist's thigh and live until the last episode. In the end, the entire court was shocked to find that the emperor was pregnant, so the female protagonist ran away with the male protagonist's child, causing the Regent to be angry and chase after her. This was a poem about a woman. The female protagonist was the emperor, and the male protagonist was the only one who was favored. I hope you like this fairy's recommendation. Muah ~😗
