Another angle could be a love story between Supergirl and Ghost Rider. It would be a very different kind of relationship, with Supergirl representing light and goodness, and Ghost Rider being a more tortured and dark figure. But perhaps their differences attract them to each other, and they have to overcome many obstacles, including the reactions of their respective friends and allies, to be together.
One possibility could be a story where Supergirl, with her super strength and flight, teams up with Ghost Rider. They could be fighting a common enemy that is causing chaos in both their worlds. Maybe a powerful demon that has escaped from the underworld and is causing havoc on Earth, and Supergirl's powers combined with Ghost Rider's hellish abilities are needed to stop it.
Perhaps there is a prophecy in the fanfiction that only Supergirl and Ghost Rider together can fulfill. This prophecy could be related to saving the multiverse from a great evil. They would have to embark on a long and dangerous journey, facing many trials along the way. Their relationship would develop from reluctant allies to true friends, and maybe even more as they grow closer through shared experiences.
Well, a really creative crossover is when they swap powers. Imagine Batman with the power of the Ghost Rider, riding his Batmobile while on fire and using the Penance Stare. It's a wild concept that makes for an exciting read.
Sure. In these crossovers, the lore of both Star Wars and Ghost Rider gets mashed up. The concept of the Force in Star Wars and the deal - making and demonic powers of Ghost Rider can create some really unique storylines. One fanfiction might have Darth Vader facing off against Ghost Rider, with Vader being both intimidated and curious about this new kind of power that seems to be a different form of the dark side he knows.
One interesting crossover could be the magic from Fairy Tail interacting with Ghost Rider's hellfire. For example, Natsu's fire magic might have an unexpected reaction when faced with Ghost Rider's hellish flames. Maybe the two could team up against a common enemy that is immune to normal forms of attack, but the combined power of Fairy Tail magic and Ghost Rider's abilities could defeat it.
One interesting crossover could be Ghost Rider teaming up with Batman. Imagine the contrast between Batman's detective skills and Ghost Rider's supernatural powers. They could face a villain who has both a criminal underworld connection and a dark magic aspect. Another could be Ghost Rider and Wonder Woman. Her strength and his hellish powers would make for an epic battle against a common enemy like Ares, who might be corrupted further by demonic forces.
A possible plot could involve the AllSpark from Transformers having an unexpected connection to the power source of Ghost Rider. Maybe the AllSpark's energy gets corrupted and Ghost Rider has to use his powers to purify it. This would bring together the two universes in a unique way and force both Ghost Rider and the Transformers to work together to save both their worlds.
A possible fanfiction could involve Bakugo. Imagine Bakugo, with his explosive temper, becoming Ghost Rider. His already fiery personality would blend well with the hellish flames of Ghost Rider. He could ride his motorcycle through the streets of the My Hero Academia cities, using his new powers to fight against villains who are more powerful than he could handle with just his Quirk. The combination of his natural combat skills and the otherworldly abilities of Ghost Rider would make for an exciting story.
One interesting crossover could be Percy using his water powers to help Supergirl when she's facing a fire - based villain. Maybe she's having trouble with a foe who can control intense heat and Percy steps in to douse the flames with his ability to manipulate water.
One interesting crossover could be the characters teaming up to fight a common supervillain. For example, Lex Luthor from Supergirl's world could team up with some of Arrow's villains like Deathstroke, and Team Arrow and Supergirl would have to combine their skills to take them down.
In a sense, it could be thought of as related to the idea of Ghost Rider fanfiction. Danny Phantom is about a boy who becomes a half - ghost and has to navigate a world of ghosts and other strange phenomena. This is somewhat similar to Ghost Rider's journey with his otherworldly powers. But Danny Phantom is an independent creation with its own lore. It has its own backstory for Danny's transformation, his relationships with other characters like his friends and family, and different antagonists. So while there may be some fanfiction - like connections, it stands on its own as a unique story.
