First, you can combine traits. For example, take a Naruto character's loyalty and combine it with an EMS - related character's technological savvy. Let's say a ninja from Naruto is paired with an EMS engineer. The ninja's determination and the engineer's creativity would make for an interesting dynamic. Second, give them common goals. If they both want to stop a powerful villain who threatens both their worlds, they'll have to learn to work together. This will force them to grow and develop new skills.
A cool plot could be a crossover where the EMS has a connection to an ancient Naruto artifact. Say, an EMS - powered device can unlock the secrets of an old, sealed jutsu. Characters from both sides would then team up to explore this mystery. They'd face challenges like different cultures clashing. The EMS characters might not understand the ninja code, and the Naruto characters would be confused by the EMS technology. This would lead to some interesting character development and interactions.
One idea could be that Naruto somehow gains the EMS (Eternal Mangekyou Sharingan) and Rinnegan powers simultaneously. Maybe through some ancient jutsu experiment gone wrong/right. He then has to learn to control these new powers while facing an old enemy who has also gained a new and dangerous power. This would lead to epic battles and Naruto exploring new ways to use these combined powers, like using EMS - enhanced speed with Rinnegan - based space - time ninjutsu.
A new character could be introduced as the main antagonist. This character could be an outcast ninja who has secretly been researching and combining the powers of EMS and Rinnegan. He believes that the ninja world should be ruled by the strongest, and he thinks he is the one. So he starts causing chaos and destruction, and Naruto has to stop him using his own EMS - Rinnegan combination.
In fanfiction, one way to combine EMS (Eternal Mangekyou Sharingan) and Rinnegan powers could be through a powerful jutsu. For example, a character might create a new form of ninjutsu that draws on the unique abilities of both. The EMS could provide enhanced visual perception and the ability to cast powerful genjutsu, while the Rinnegan could offer control over different elements and the six paths techniques. They could be combined in a way that allows for teleportation between different dimensions, using the space - time manipulation aspects of both powers.
Power is a common theme. Since the EMS gives such great power, many fanfictions explore how the characters handle it. Another theme is legacy, as the EMS is often seen as a part of a family's or clan's power heritage. And there's also the theme of redemption in some cases, where a character uses the EMS to make up for past wrongs.
It could be interesting to see Naruto with both EMS and Rinnegan in fanfiction. Naruto is known for his Uzumaki vitality and his ability to master new powers quickly. Having EMS and Rinnegan would give him an entirely different set of skills. He could combine the Rasengan with Rinnegan - based techniques and use the EMS - enhanced perception to dodge attacks even better. His positive attitude and never - give - up spirit would make for an exciting exploration of these powers.
