In some fanfictions, Snape has badass moments when he outsmarts Voldemort. For example, he manages to mislead Voldemort about the location of a crucial magical artifact. He uses his Occlumency skills to his advantage, hiding his true thoughts and intentions while presenting false information in a very clever way. This not only shows his intelligence but also his courage as he risks his life to deceive the Dark Lord.
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.
There could be a moment where Percy stands up to an unjust authority figure in the fanfiction world. He defies them with such confidence and charisma that it makes him seem like a total badass.

One possible badass moment could be when bella stands up to a powerful alpha wolf. She shows no fear and uses her sharp tongue to put the wolf in its place.

One badass moment could be when Ezra single - handedly takes on a group of stormtroopers in a narrow corridor. Using his lightsaber and the Force to deflect blaster bolts back at them, he cuts through their ranks like a hot knife through butter. Another might be when he uses his Force powers to manipulate a large ship's controls from a distance to prevent it from crashing into a rebel base.
One common theme is the idea of sacrifice. The badass warrior often has to sacrifice something for the person they love. For example, in 'Akame ga Kill!', Tatsumi sacrifices his own safety and well - being for Akame and their comrades. Another theme is growth. The love story often forces the warrior to grow as a person. In 'Rurouni Kenshin', Kenshin grows and changes because of his relationship with Kaoru. He becomes more open and less isolated.
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.
One great anime is 'Akame ga Kill!'. It features a group of badass warriors fighting against a corrupt empire. Tatsumi, one of the main characters, has a complex relationship with Akame, which includes elements of love. Their story is filled with action, sacrifice, and a touch of romance.
