Another approach could be a crossover with a fantasy series like The Lord of the Rings. Nightmare could find himself in Middle - earth, perhaps being mistaken for a powerful dark entity. This would lead to him having to deal with the various races and powers there, and it could be really interesting to see how he interacts with characters like Aragorn or Gandalf.
A more unique idea might be to cross Nightmare with a character from a sci - fi universe, say, a Cybernetic warrior. The fanfiction could focus on how Nightmare's ancient, mystical powers interact with the advanced technology of the cybernetic being. There could be a struggle for control over a powerful energy source that has the potential to change both their worlds.
Study the body language and dialogue styles of both characters. If Nightmare is interacting with a more talkative character like Dante from Devil May Cry, Nightmare's more brooding and menacing presence can be contrasted with Dante's witty and confident banter. Their body language would also be different, with Nightmare perhaps having a more imposing stance while Dante is more relaxed but ready to strike at any moment.
A great Soul Calibur crossover fanfiction idea could involve a crossover with the Street Fighter series. The diverse fighting styles of Street Fighter characters like Ryu and Chun - Li could clash or collaborate with those from Soul Calibur in an epic battle - filled story. Also, a crossover with the God of War universe would be intense. Kratos' brutal combat style against the Soul Calibur characters would be a sight to behold. Or, consider a crossover with the Kingdom Hearts series, where the Heartless could add an extra layer of danger to the Soul Calibur world.
First, choose the crossover universe carefully. Decide which other franchise or world you want to blend with Soul Calibur. Then, research both universes thoroughly. Know the characters, their abilities, and the lore. Next, come up with a basic plot. It could be a conflict, a quest, or a mystery that involves characters from both worlds. After that, start writing the introduction, introducing the setting and the main characters.
Power dynamics is another theme. Nightmare is a very powerful character, and Tira is also quite formidable in her own way. Fanfics may show how they vie for power or how one submits to the other in different situations, adding an interesting layer to their relationship.
It could be someone like Naruto himself. With his ability to use massive amounts of chakra and his powerful jutsus, he would be a formidable force in the Soul Calibur world. He could also learn to use Soul Calibur weapons, making him even more powerful.
I'm not sure of the exact titles, but you can try searching on fanfic platforms like FanFiction.net or Archive of Our Own. Look for tags like 'Soul Calibur', 'Nightmare', and 'Tira' to find relevant fanfics.

One idea could be a crossover between a horror movie like 'Nightmare on Elm Street' and a popular fantasy series such as 'Harry Potter'. Imagine Freddy Krueger showing up in Hogwarts, causing chaos among the students. Another could be a crossover with 'The Walking Dead', where the nightmares of the apocalypse blend with the already terrifying world of the undead. Or perhaps a crossover with a superhero universe, like 'Marvel', where the heroes have to face their worst nightmares in a new and unexpected way.
One idea could be a crossover with the 'Lord of the Rings' universe. The Soul of Cinder could be a powerful entity that somehow ends up in Middle - earth. Maybe it's mistaken for a dark lord by some and has to prove its true nature. Another option is a crossover with 'Final Fantasy'. The Soul of Cinder's abilities could be translated into the magic and combat system of 'Final Fantasy', creating some really interesting battles.
