Well, I really liked 'The Unseen Bond' fanfic about azazel and nightcrawler. It focuses on the emotional side of their relationship. It shows how Nightcrawler struggles with the fact that Azazel is his father. And then there's 'Azazel's Redemption Arc' which is quite unique. It gives Azazel a chance to redeem himself through his relationship with Nightcrawler. Also, 'Nightcrawler's Journey with Azazel' is a good read as it takes the two on an adventure together.
Summoning a demon in comics often requires a combination of factors. It could involve knowing specific spells, having access to forbidden knowledge, or being in a particular supernatural setting. But remember, it's all fictional!
In such a fanfiction, Naruto being the son of Azazel would bring a whole new dynamic. His chakra could be seen as a unique form of power in the Highschool DxD universe. He could potentially use it to enhance his physical abilities even more than the normal characters in that world. And his rasengan? It could be a really powerful attack against the various creatures in the story. He might also have some internal conflict about his heritage, being part - ninja and part - fallen angel.
Common themes in azazel x riptide fanfiction include exploration of their different personalities. Since they are likely different in nature, how they complement or clash with each other can be a major theme. The theme of sacrifice might also be there. In a dangerous situation, one character might be willing to sacrifice for the other. And there's often the theme of discovery, whether it's about themselves, their relationship, or the world around them.
One interesting Azazel fanfiction could be one where he mentors the main character in a more in - depth way, exploring his knowledge and skills. For example, a story where he takes the protagonist on a journey through different dimensions to teach about the various supernatural elements in the Highschool DxD universe.
One prevalent theme is likely to be the battle between good and evil. Given the nature of the characters, Issei as the son of Azazel may be caught in the middle of this eternal struggle. He may have to decide which side to take or find a way to balance the two. There could also be themes related to family secrets and the revelations that come with uncovering them, which add to the drama and intrigue in the fanfiction.
Well, it might be someone like Vali. He has his own sense of justice and is extremely powerful. In fanfiction, the author could easily shape him into a heroic heir. He has a complex personality and his interactions with Azazel could lead to a great storyline with him as the heroic figure.
The complex relationship between them. Azazel being Nightcrawler's father yet having a dark and mysterious past. It's like a puzzle that fanfic writers can play with.
