Fanfiction about Naruto and Selene in the Underworld: What could be the possible plotlines?

A plotline could involve Selene's pregnancy causing a rift in the vampire community. Some vampires might see the child as a threat to their traditional ways or a potential source of power. So, Selene has to deal with not only the physical and emotional aspects of pregnancy but also the political turmoil within her own kind.

There could also be original characters created specifically for the fanfiction. These characters could be hybrids of the Naruto and Selene universes, perhaps having a mix of ninja abilities and Underworld powers. They could add new dimensions to the story and help drive the plot forward, whether as friends or foes to Naruto and Selene.

Some fanfictions could explore the idea of Selene teaching Naruto about the secrets of the Underworld. Naruto, in turn, could show Selene his ninja way and how determination and hard work can overcome great obstacles. This could lead to a series of adventures as they explore different regions of the Underworld together.

Well, Naruto's Nine - Tails chakra is a huge power source. If he were to share some of that chakra with Selene, she could gain new abilities. Maybe she could use it to create a powerful shield around them, since the Nine - Tails' chakra is known for its raw power. On the other hand, Selene's power to control the blood of her enemies could be used to immobilize opponents while Naruto prepares his more complex jutsus. Their combined powers would be a very interesting and powerful mix that could be used to overcome many difficult challenges in the Underworld.

One possible fanfiction could be that Selene and Michael's pregnancy is a sign of hope for the vampire and lycan clans. Their child could be seen as a symbol of unity, bringing an end to the long - standing feud. Maybe in the story, they have to face many challenges during the pregnancy, like threats from those who oppose the union of a vampire and a lycan.

The plot could also involve a time - related crisis. Maybe something is threatening the timeline, and the only way to fix it is for future Naruto to raise his younger self in a certain way. So, future Naruto has to make sure that the younger Naruto grows up to be strong enough to face this threat while also maintaining the integrity of the timeline.

One possible plotline could be that Naruto somehow ends up in Akeno's world. They meet and at first Akeno is a bit shy around Naruto. Naruto, with his positive attitude, gradually befriends her. They could go on adventures together, like facing some common enemies in Akeno's realm. Naruto's ninja skills would be very useful in such situations.

One possible plotline could be that Naruto is in a life - threatening battle against a powerful enemy. Gaara arrives just in time, using his sand powers to shield Naruto from a fatal attack. Then they team up, with Gaara's strategic thinking and Naruto's unwavering determination, they gradually turn the tide of the battle.

One possible plotline could be that Naruto is somehow mind - controlled. Maybe an enemy uses a powerful genjutsu on him, making him see the Konoha 12 as threats to the village instead of comrades. This would lead to a tragic situation where Naruto, in his altered state of mind, attacks them.

Perhaps the plot could start with Yugito initially being a normal acquaintance of Naruto. But after some incident, like Naruto saving her life, her feelings turn into a yandere - like obsession. She then starts following Naruto everywhere, much to his confusion at first. As the story progresses, Naruto has to figure out how to deal with her obsessive behavior without hurting her feelings too much, while also maintaining his own goals and relationships.
