Who could be some good characters to include in a 'Shadow of War Crossover Fanfiction'?

Clary Fray would be a great character to include as she is one of the main characters in the Shadow Hunter world. Her skills and determination can add a lot to a crossover story.

If you're doing a crossover with the Mass Effect series, Shepard could be a great character to include. Shepard's leadership and combat experience against various alien races would be interesting when paired with the Horsemen's fight against the forces of Hell. Also, including some of the alien species from Mass Effect like the Krogan or the Asari could create some really cool interactions.

If it's a crossover with 'Ice Age', Manny the mammoth would be a great addition. His calm and gentle nature could contrast with Grug's over - protective and sometimes gruff attitude. Sid the sloth could also bring some comical relief with his goofy antics.

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.

Hermione Granger from 'Harry Potter' could be an interesting addition. She could use her magic knowledge to study the mummy. Maybe she could find a spell to control or at least understand the mummy better. It would be a really unique combination of magic and ancient Egyptian mystery.

Professor Oak could also be an interesting addition. As a Pokémon expert, he might be fascinated by Mewtwo and try to study it. This could create a conflict as Mewtwo is not one to be easily studied. It could also lead to a deeper understanding of Mewtwo's origin and abilities.

Batman would be a great character to include. His no - kill rule contrasts with Deadshot's assassin nature. Their interactions would be full of tension and moral debates. Harley Quinn could also be included. Her chaotic personality could add an element of unpredictability to the story. She might team up with Deadshot for a mission or be a distraction during one of his hits.

Simba from 'The Lion King' would also fit well. His experience of losing his kingdom and then reclaiming it is similar to Moses' story in some ways. They could bond over their shared experiences of exile and the journey to regain their rightful place.

In a crossover with a detective story, a smart detective character would fit well. He or she could initially be suspicious of Radio Rebel's anonymous radio persona but then come to realize that she can be a valuable asset in solving a big mystery. They could work together to uncover secrets in the city, with Radio Rebel using her radio show to gather tips from the public.

Goku from Dragon Ball would be an obvious choice. Since Beerus is from the Dragon Ball universe already, their interactions are always full of energy and interesting power dynamics. They could team up against a new, powerful enemy that threatens both of their worlds in the crossover.
