What could be an interesting plot for a Marvel and Dragon Ball Z crossover fanfic?

The plot might involve a villain who has the ability to steal both ki and chakra. This forces Goku and Naruto to team up. Goku, with his Super Saiyan forms, provides brute strength, while Naruto, with his various jutsu like Rasengan and his Sage Mode, offers strategic combat skills. They would have to combine their powers in unique ways to defeat this new threat.

A cool plot could be a tournament - style crossover. A powerful being from another dimension decides to host a tournament where fighters from Dragon Ball Z and Devilman are invited. Characters like Vegeta and Devilman's friend Akira Fudo would compete. There could be unexpected alliances and rivalries. For example, Piccolo might initially see Devilman as a threat but later realize they have a common goal of protecting their respective worlds. And in the end, they all have to team up against the true evil that the tournament organizer has in store.

A plot might involve the Dragon Balls being scattered across the Bleach universe. Ichigo hears rumors about these powerful orbs and starts looking for them. Meanwhile, Goku and his friends also end up in the Bleach world while searching for the Dragon Balls. They meet the Soul Reapers and at first there's some tension. But as they learn more about each other's goals, they work together. The Soul Reapers are fascinated by Goku's power and training methods, and Goku is intrigued by the concept of souls and the afterlife in the Bleach world.

One interesting storyline could be Goku teaming up with Iron Man. Goku's raw power and martial arts skills combined with Iron Man's high - tech gadgets would make for an epic battle against a common enemy like Thanos. They could learn from each other's fighting styles and strategies. Another could be Vegeta and Captain America. Vegeta's pride and determination would clash and also blend well with Captain America's leadership and unwavering sense of justice. A third storyline could involve the Z - Fighters helping the X - Men deal with a mutant - hating villain. The Z - Fighters' unique powers would add a new dimension to the X - Men's battles.

One interesting plot point is the power - level comparison. In these crossovers, fans often get to see how the powerful ninjas from Naruto stack up against the super - powered Saiyans from Dragon Ball Z. It's fascinating to imagine a fight between Naruto's Sage Mode and Goku's Super Saiyan form.

A cool plot might involve a rift in space - time that pulls the Dragon Ball Z world and the DC Universe together. Vegeta could be at odds with Wonder Woman at first, seeing her as a rival in terms of strength and combat skills. The Justice League and the Z Fighters then discover that an ancient evil force from both of their universes' pasts has been awakened. They must learn to work together, with Gohan and Robin sharing their intelligence to figure out a plan. The Saiyans' transformation abilities and the Justice League's various powers like the Flash's speed would be crucial in the final battle against this evil.

Perhaps a magic spell in the Fairy Tail world goes wrong and creates a portal that sucks in some of the main characters from Dragon Ball Z. Vegeta, for example, would initially be angry about being in this strange new place but would soon realize that there are powerful foes and allies here. The Fairy Tail guild could hold a tournament to see who is the strongest among them and the Saiyans join in. This would lead to epic battles and also some comical moments as the two groups with very different cultures try to understand each other.

One possible plot could be that Luffy and his crew are sailing in the Grand Line when they encounter a strange energy. It turns out to be a Dragon Ball. They then have to deal with various villains from both universes trying to get the ball. Maybe Frieza hears about it and teams up with some of the pirates from One Piece. And Goku, sensing the power of the Dragon Ball, also arrives in the One Piece world to help Luffy protect it.

Perhaps the Dragon Balls get scattered across the Yu - Gi - Oh world. Yugi and his friends, along with Goku and the Z - fighters, have to search for them. But there are evil forces in the Yu - Gi - Oh world that want to use the Dragon Balls for their own gain. So, they have to battle these foes while also dealing with the various challenges and mysteries of the Yu - Gi - Oh universe, like the different types of card decks and the power of the Shadow Realm.

One idea could be to combine the power - up mechanics of Dragon Ball Z with the strategic battles of Fire Emblem. For example, characters in the fanfic could gain new abilities similar to Super Saiyan transformations during intense battles in the Fire Emblem - like battlefields. They could use these new powers to turn the tide of the fight against the enemy forces, which could be a mix of both Dragon Ball Z villains and Fire Emblem antagonists.
