There could be a plot where Zatanna has to help Spiderman when he gets caught in a magical curse. Spiderman loses his powers or is turned into something else, and Zatanna uses her magic to figure out how to reverse it. This allows for a lot of exploration of both characters' abilities and their friendship as they face this challenge together.
One idea could be that Zatanna is magically transported to the Harry Potter universe. She uses her unique magic skills to help Harry and his friends in a difficult situation, like during a battle against Voldemort. Maybe she could use her magic to create illusions to deceive the Death Eaters.
One idea could be that Spiderman 2099 has to team up with a group of rebels from a future dystopia to take down a powerful corporation that controls the city. They might face advanced technology and dangerous enforcers.
Another idea is a time - travel fanfiction. Spider - Man could be sent back in time to when his Uncle Ben was still alive. He would have the chance to prevent his uncle's death, but he'd also have to deal with the consequences of changing the timeline, like how it might affect his own development as a hero.
One plot idea could be that Superboy and Zatanna are sent on a mission together to a magical realm. There, they have to combine Superboy's strength and Zatanna's magic to defeat an ancient evil. Another could be a story where Zatanna accidentally casts a spell on Superboy that gives him temporary magical powers, and they have to figure out how to reverse it while also dealing with villains who want to use Superboy's new powers for their own gain. A third idea is that they discover a connection between Kryptonian technology and ancient magic, and they must work together to stop a mad scientist from misusing this knowledge.
A story could be set in a future where the worlds of Marvel and DC have merged. Spiderman and Starfire are part of a new superhero team. They have to deal with the cultural differences between their two groups of heroes as well as face off against new villains created by the merger of the two universes.
One idea could be exploring what would happen if Spider - Man had to team up with a villain to stop a greater threat. For example, partnering with Doctor Octopus to take on an alien invasion.
One idea could be that Spider - Man has to face a new villain who has the power to manipulate his darkest fears and turn them into reality. Another could be a version where Spider - Man is wrongly accused of a major crime and has to clear his name while also dealing with the city turning against him.
A cool plot could be that there is a glitch in the game world that starts causing real - world disasters. Spiderman has to figure out how to fix the glitch by going deeper into the game code, all while still dealing with his regular villains.
One idea could be exploring how they balance their superhero duties with the impending arrival of a baby. Maybe they start training a new generation of heroes early, like teaching their unborn child's future friends or sidekicks some basic skills. Another plot could involve the magical and technological challenges of protecting the baby. Since Batman has his high - tech gadgets and Zatanna has her magic, they could combine forces to create a super - safe nursery protected by both technology and magic spells.
Another idea is that the OC is a non - magic user who gets caught in a magical conflict that Zatanna is involved in. The OC has to rely on their wits and physical skills while Zatanna uses her magic. Their relationship could grow as they learn from each other's strengths and weaknesses. For example, the OC might teach Zatanna some street - smart tactics, and Zatanna could introduce the OC to the world of magic.
