The characters from Danmachi could have a range of reactions to Fate fanfiction. Some might be confused at first, especially if the fanfiction has very complex Fate lore. However, those who are more open - minded, like Bell, might be excited to explore new stories and ideas. He could see similarities in the way heroes are portrayed in both worlds and be inspired by it.
One way a Danmachi - Fate fanfiction crossover could function is through the concept of parallel universes. The two universes could be connected in some way, and certain events could cause portals to open between them. In this scenario, the adventurers from Danmachi would enter the Fate world. They would be faced with the complex politics and power struggles there. The Fate characters might view the Danmachi characters as strange new entities. There could be a lot of misunderstandings at first, but as they get to know each other, they could learn from each other's strengths. For example, the Danmachi characters could learn about the strategic use of Command Spells from the Fate characters, while the Fate characters could be impressed by the physical combat skills of the Danmachi adventurers.
A third idea is a crossover where the characters from both universes have to team up to face a common enemy. Maybe an ancient evil that threatens both the world of Fate and the DxD world. They would need to combine their powers and strategies, like the devils using their demonic powers along with the Servants' unique abilities.
Issei is often a popular character in Fate DxD Gamer fanfiction. His original character traits from DxD can be enhanced or modified in interesting ways due to the gamer elements. For instance, he might gain new leveling systems related to his perverted nature, which could be both humorous and add a new layer to his character development.
First, you need to have a solid understanding of both universes. Know the rules, the characters, and the powers in Fate and DxD. This will help you create a believable crossover. For instance, if you're bringing a Fate character into the DxD world, you have to consider how their magic will work in a world full of devils and angels.
One interesting Fate DxD Gamer fanfiction could be the one where the main character uses their gamer skills to outwit devils in the DxD universe. For example, they might use strategic thinking similar to a game strategy to overcome challenges in the Rating Games.
One great Fate fanfiction in the context of a Highschool DxD reader is 'Fate/Highschool DxD Crossover.' It combines the exciting elements of both universes really well. The characters from Fate interact in an interesting way with those from Highschool DxD, and the plot has some great twists.
One idea could be to have the Servants from Fate interact with the Devils in DxD in a battle royale setting. Maybe the Holy Grail somehow ends up in the DxD universe and all the factions are after it.
Rias Gremory remains a popular choice. She is a central figure in DxD, and when combined with the Fate system, her leadership and her own powers can be explored in new ways. For example, how she might strategize against opponents who use Fate - based powers or how she might incorporate such powers into her own devilish abilities. Plus, her romantic and friendly relationships are always interesting to see in the context of this fanfiction.
Well, in 'Fate System DxD Fanfiction', the idea of how different Servants from the Fate series interact with the Devils in DxD is really cool. For example, a heroic spirit like Archer might have some really interesting exchanges with Rias or other devil characters. They could share their combat experiences or knowledge about different forms of power, which would be a great source of character development and plot twists.
