One idea could be a crossover where Naruto characters find themselves in the dark and Gothic world of Castlevania: Lords of Shadow 2. For example, Naruto's ability to use chakra could be pitted against the dark magic of the Castlevania universe. Maybe Naruto and his friends have to team up with the protagonist of Lords of Shadow 2 to defeat a common enemy that threatens both their worlds.
One common theme is the struggle between good and evil. In a crossover, the characters from Castlevania Lords of Shadow 2 often bring their own moral compasses and have to navigate the moral landscapes of the other universe they cross into. Another theme is power. How the powers of the characters from Lords of Shadow 2 compare and interact with the powers in the crossover universe can be really interesting.
Well, in Castlevania Lords of Shadow, Gabriel is a key figure. His love for Marie drives him. He travels through a dark and dangerous world filled with gothic horror elements. He gradually uncovers that there are greater forces at play. He gets powers from different sources during his adventures. As he battles the Lords of Shadow, he becomes more and more entwined in a web of secrets and prophecies. In the end, his actions have far - reaching consequences for both the living and the dead.
First, you need to research both universes thoroughly. Know the characters, their abilities, and the settings well. For Naruto, understand the different ninja clans, jutsus, and the overall ninja world. For Castlevania: Lords of Shadow 2, study the lore of the vampires, the dark magic, and the various locations. Then, come up with an interesting premise for the crossover. It could be a conflict that brings the two worlds together, like a dark force that threatens both Naruto's world and the Castlevania world.
Well, a really interesting 'Castlevania Lords of Shadow Laura fanfic' might be one that pairs her up with an unexpected character. For example, a fanfic where she teams up with a minor character from the game world to fight a new threat. This could create a whole new dynamic and story arc. Also, a fanfic that explores Laura's connection to the magic or dark elements in the game's world in a more in - depth way can be very engaging. It could show how she might have been affected by the dark forces around her and how she copes with it.
One idea could be exploring the backstory of a minor character in the game. For example, a sidekick of the main protagonist who has their own motives and secrets that tie into the overall lore of the Castlevania Lords of Shadow universe.
I really like 'Carmilla's Scheme in Dracula's Realm'. In this fanfic, Carmilla is depicted as a very cunning character who is constantly plotting within Dracula's castle. It gives a lot of depth to her character. As for Dracula, his power and brooding nature are well - presented. There's also 'Alliance of the Dark' which shows an unlikely alliance between them against a common enemy. It's a great read if you want to see them interact in a different way than in the original series.
Well, Reddit can be a good place to start. There are some subreddits dedicated to Castlevania fanfics. You can post a request for Laura - focused fanfics in those subreddits and the community might be able to point you in the right direction. Additionally, some Castlevania fan forums might have sections dedicated to fanfics where you can find 'Castlevania Lords of Shadow Laura fanfic'.
Sora from Kingdom Hearts could be a fun addition. His positive attitude and his ability to use keyblades and magic would be a different take in the dark Castlevania setting. He could bring a sense of hope and light to the story. Also, Cloud Strife from Final Fantasy VII. His Buster Sword skills and his experience in fighting against powerful foes like Sephiroth could translate well in the battles against the lords and demons in Castlevania Lords of Shadow. His stoic personality would also create an interesting dynamic with the more emotional characters in the game.
