Another could be a crossover with the DC Universe, where Vegeta and Superman have a showdown to see who's stronger. Or perhaps a crossover with the Final Fantasy series, with the Dragon Ball characters in a world filled with magic and summons.

One idea could be that Goku and Naruto meet during a universal tournament. Goku, being his usual self, is excited to fight strong opponents. Naruto, on the other hand, is intrigued by Goku's pure love for combat. They could team up against a powerful enemy from another dimension who threatens both their worlds.

One idea could be that Naruto and Goku meet during a interdimensional rift. They decide to have a friendly spar, with Naruto using his shadow clones and Rasengan while Goku goes Super Saiyan. Another could be that the Akatsuki are after the Dragon Balls for some reason, and the Z - fighters team up with the ninja of Konoha to stop them.

One idea could be a crossover with the Naruto universe. Imagine Goku meeting Naruto and them having a friendly sparring match. Another could be a crossover with the One Piece world, where the Z - fighters team up with the Straw Hat Pirates to take on a common enemy. And a crossover with the Harry Potter universe, with the Saiyans learning magic at Hogwarts.

A great 'Dragon Ball Super Crossover Fanfiction' concept might involve a crossover with the Harry Potter world. The Saiyans could visit Hogwarts. Maybe Vegeta could be really intrigued by the magic there and try to learn some spells, while at the same time the wizards are in awe of the Saiyans' power. There could be a dark wizard who wants to use the Dragon Balls for his own evil purposes, and the Hogwarts students and the Z - fighters have to work together to stop him.

One idea could be a battle between Goku and Superman. They could start off as rivals, each thinking their own planet needs more protection. As they fight, they gradually realize they have more in common than they thought, like their strong sense of justice. Then they team up to face a common enemy, like Darkseid and Frieza working together.

A crossover with the One Piece universe could also be cool. Imagine Luffy and Goku having a friendly competition to see who can defeat more enemies. The different power systems, like Devil Fruits and ki, would create interesting battles and interactions.

One interesting idea could be how the concept of hypnosis is integrated into the Dragon Ball universe. Maybe it's used as a new form of combat strategy, where a character hypnotizes their opponent to lower their guard or make them perform certain actions against their will.

One idea could be exploring Cus's training in a new dimension. Maybe she discovers a hidden power within herself during a sparring session with an unknown opponent.
