In this fanfiction, a really exciting crossover would be the Pokemon trainers from the Pokemon world coming to the Naruto world during the Fourth War. They could use their Pokemon to fight against the powerful ninja enemies. For instance, Ash could arrive with his Pikachu and team up with Naruto. The different strategies of Pokemon battles and ninja battles could be combined. The Pokemon could also provide unique support, like a Chansey using its healing abilities to help the injured ninja on the battlefield.
One exciting crossover could be a battle between Naruto and a Kryptonian. Imagine Naruto's ninjutsu against the super strength and flight of a Kryptonian. And if a Saiyan were added to the mix, like Goku, the power levels would be off the charts. The Saiyan's ability to transform and gain power could make for an epic three - way battle.
In this kind of fanfiction, there could be a crossover where the Pokemon world's healing techniques are combined with Naruto's medical ninjutsu. Since there's the 'immortal' aspect, perhaps an elixir from the Pokemon world that grants immortality is sought after in the Naruto world. Also, the different regions in the Pokemon world could be like hidden villages in Naruto. Trainers from the Pokemon world could come to the Naruto world to learn about chakra, and Naruto characters could go to the Pokemon world to understand their unique powers.
In Naruto Pokemon God fanfiction, the idea of the Pokemon world's gods having an impact on the Naruto world is very popular. For instance, the god of Pokemon like Dialga could manipulate time in the Naruto universe. Or Giratina could be involved in the darker aspects of the Naruto world, like the Orochimaru - like experiments. And many fanfictions explore how the Pokemon themselves would adapt to the chakra - based environment of the Naruto world.
One exciting crossover could be Naruto using his godlike powers in the Devil May Cry universe. He might use his shadow clones to outwit the demons. Another could be Dante teaching Naruto some sword - fighting skills, which Naruto could then combine with his own ninja techniques. It would be really cool to see Naruto's rasengan in the Devil May Cry setting, perhaps modified with some Devil May Cry magic for an even more powerful attack.
The Goku vs. Hulk crossover is really exciting. Goku's speed and strength against Hulk's brute force is a great matchup. Goku's ability to move at super - fast speeds and land powerful blows, while Hulk just gets stronger as he gets angrier. It's a battle of different power dynamics.
A Naruto and One Piece crossover is likely to be popular as well. The idea of Naruto and his friends joining Luffy on his pirate adventures, exploring the different islands and facing the various pirates and marines, is really appealing to fans.
The characters' abilities can combine in interesting ways. For example, a ninja like Sakura could use her superhuman strength along with a Pokemon's physical attack. So if she teams up with a Machamp, they could deliver some really powerful punches. Naruto's ability to create multiple clones could be used in combination with a Pokemon that has a wide - area attack move. He could send out his clones and then have a Pokemon like Gardevoir use Psychic to attack a large group of enemies all at once.
Well, a really cool crossover in a Pirate Naruto x One Piece fanfic could be the sharing of abilities. For example, if Zoro was able to learn some chakra control from Naruto, he might be able to enhance his sword attacks with an extra energy source. Also, the ninjas from Naruto's world could teach the One Piece characters some stealth techniques, which would be very useful for the Straw Hats when they are sneaking onto an enemy ship.
One of the most heartbreaking scenes could be when his friends find out about Naruto's death. For example, Sakura, who has been with Naruto through so much, would be completely shattered. Her reaction of disbelief and then overwhelming grief would be really sad. Another scene might be when the whole village of Konoha hears the news. The silence that would fall over the village, with people just stopping in their tracks, would be a very poignant moment.
A really interesting crossover is when the Fruits Basket characters' zodiac animals are related to specific Pokemon types. For example, the rat character could be associated with a Pikachu - like electric type Pokemon. It creates a whole new dynamic.
