The theme of identity often comes up. Naruto has a strong sense of self - identity based on his village and his ninja way. Lucifer also has a complex identity. When they meet in fanfiction, they may question or redefine each other's identities. For instance, Naruto might make Lucifer question his own nature as an 'evil' being.
Power and its consequences are also a big theme. Naruto has his own set of powers in his universe, and when combined with Lucifer - who is often depicted as extremely powerful - it explores how these powers can be used, misused, or how they change the characters. This can lead to themes of corruption or self - discovery through power.
A common theme is the clash of different moralities. Naruto is from a world with a strong sense of right and wrong, while Lucifer has a more complex moral standing. Another theme could be power exchange. Maybe Naruto is offered power by Lucifer in exchange for something.
Friendship and rivalry are also common themes. Characters from Naruto and Highschool DxD may form new friendships or become rivals. For example, Naruto's friendly and outgoing nature might lead him to make friends with some of the characters in Highschool DxD, but his power also might make others see him as a rival. And in some fanfictions, the Lucifer aspect might add an extra layer of mystery or power dynamic to these relationships.
One common theme is redemption. When Lucifer is hurt, it can be a starting point for him to seek redemption for his past wrongdoings.
One common theme is loyalty. Fans often explore how Lucifer and Maze stay loyal to each other despite all the challenges they face. Another theme is self - discovery. Maze, in particular, is often on a journey to find out more about herself, and this is reflected in many fanfictions. And of course, friendship is a big theme. Their unique friendship, which is full of banter and deep understanding, is a central focus in a lot of fan - created stories.
Another theme is the exploration of good and evil. Since Lucifer is associated with evil in many ways, the oc's presence can either sway him towards good or they both end up in a moral gray area. It makes for really thought - provoking stories.
Redemption is also a big one. Given Lucifer's character arc in the show, fanfiction often delves deeper into his journey of self - discovery and redemption, especially in relation to Chloe. She's like his anchor in this process. For example, in many fics, we see how he tries to be a better person because of his love for her.
One common theme could be redemption. Despite being abused, Lucifer may strive for redemption. Another might be power struggles, as he tries to regain his power after being in an abused situation.
One common theme is love conquers all. Their relationship often faces various challenges like Lucifer's devilish nature and Chloe's human morals, but love always seems to prevail in these fanfictions.
One common theme is the struggle between good and evil within Lucifer himself. He is often depicted as a complex character who has both the capacity for great darkness but also some remnants of his former angelic self. Another theme is the exploration of power. Since Lucifer is a powerful being, his use and abuse of power in a dark context is often explored.
The theme of Lucifer's struggle with his devilish nature and Chloe's influence on him is also quite prevalent. Chloe represents the good and the human side, and she often challenges Lucifer to be better. Fanfiction might explore how he changes over time because of her. Also, the idea of their eternal bond, whether it's fated or just a strong connection they've developed, is a popular theme.
