One idea could be that Naruto discovers Bakugan in his world somehow. Maybe during a mission in a mysterious forest, he stumbles upon a Bakugan and its Gate Card. He then has to figure out how to use it, and it could potentially give him new powers. Another plot could involve Naruto and his friends teaming up with Bakugan brawlers from another dimension to fight a common enemy that threatens both their worlds. This would bring in the unique abilities of the Bakugan and the ninja skills of Naruto and his comrades.
Well, a cool plot could be that the Akatsuki is interested in the Bakugan for some reason. They start collecting them to use in their plans for world domination. Naruto, being Naruto, decides to stop them. He meets a Bakugan expert who tells him that only a true hero can master the Bakugan. Naruto then embarks on a journey to become that hero and take on the Akatsuki. In this fanfic, the Bakugan could have different abilities based on the ninja elements like fire, water, etc.
One idea could be a story where Apollonir is lost in a strange dimension and has to find his way back while facing various new Bakugan threats. He could make unexpected allies along the way.
Well, a great plot could be centered around a mystery. Let's say there are strange occurrences in their world that seem to be related to Bakugan Shadow's past. Mylene becomes determined to solve this mystery. As they dig deeper, they uncover secrets that not only change their understanding of Bakugan Shadow but also put them in danger. They might have to face off against an ancient enemy who is trying to keep these secrets buried. Mylene uses her intelligence and courage, while Bakugan Shadow uses its strength and special powers to overcome the obstacles in their path.
A plot could involve a group of Gundalians and Earthlings teaming up to face a new, powerful threat that is neither from their world. This new threat could be a mysterious entity that has the ability to corrupt Bakugan and they have to find a way to stop it before all Bakugan are affected. They would need to combine their knowledge and skills to overcome this. For example, the Gundalians might know some ancient techniques to purify Bakugan while the Earthlings could contribute their strategic thinking developed from their own battles.
A really interesting plot for a Bakugan Drago x Wavern fanfiction could be set in an alternate universe. In this universe, Drago and Wavern are from different factions that are at war. They meet by chance and initially are hostile towards each other. But as they get to know each other better, they start to question the reasons for the war. They then have to decide whether to follow their factions or side with each other and try to bring peace to this alternate Bakugan world. This would involve a lot of character development and exploration of their relationship in a complex and unique setting.
One idea could be a crossover where Naruto's world and the world of X - 23 from the X - Men collide. Maybe X - 23 is on a mission and accidentally ends up in the Hidden Leaf Village. She has to learn to adapt to this new place with its different culture and ninja ways. Naruto could be intrigued by her and her abilities, and they could team up to face a common enemy.
Maybe a plot where Alice and Masquerade are forced to team up. They could be in a situation where they have to battle a common enemy that is far more powerful than either of them alone. At first, they might be hesitant and full of mistrust, but as they fight together, they start to understand each other better and develop a strange sort of friendship. This could also involve exploring their different fighting styles and how they combine them to defeat the enemy.
Perhaps Neo could teach Naruto about the concept of the digital world, which Naruto then uses to create a new form of jutsu. Meanwhile, Naruto could show Neo the power of friendship and teamwork in the ninja way, changing Neo's perspective on fighting.
One idea could be that Inari, inspired by Naruto's determination, decides to train hard and develop his own unique ninja skills. He could then join Naruto on a small mission in the Land of Waves and prove his worth. Another plot could be a time - travel plot where Naruto is sent back in time to when Inari was a child and he has to protect Inari and his mother from Gato's men in a different way, changing the course of history in the Land of Waves.
One idea could be that Naruto and Erza are brought together by a powerful magic spell that transports Naruto to the Fairy Tail world. They initially misunderstand each other due to their different backgrounds and abilities. But as they face common enemies, they start to learn from one another. Naruto could teach Erza about his ninja way of never giving up, and Erza could show Naruto the power of magic and the importance of friendship within the guild.
A plot where Naruto and Boruto have to team up to fight a new, powerful enemy that neither could defeat alone. This would allow for some great father - son bonding moments and also show how their skills complement each other. For example, Naruto's brute strength combined with Boruto's unique ninja techniques. It could also explore how Naruto imparts his wisdom about the ninja way to Boruto during the battle.
