What are some interesting plot ideas for a 'naruto meets star butterfly' fanfiction?

In this fanfiction, perhaps they would team up to fight a common enemy. Star Butterfly's unique magical powers combined with Naruto's strength as a ninja would make for an interesting battle. They could be in a world that has elements of both their universes, and they'd have to figure out how to work together. For example, Naruto could use his speed and stealth to get close to the enemy while Star Butterfly uses her magic to distract or weaken the foe from a distance.

One plot idea could be that Stanford Pines discovers a portal to Star Butterfly's dimension. He teams up with Star to stop an evil force that is threatening both their worlds. Maybe it's an ancient entity that has the power to disrupt magic in Mewni and the strange anomalies in Gravity Falls.

One idea could be a character with the butterfly bloodline being an outcast in the Hidden Leaf Village at first. Because their abilities seem so strange compared to the common ninja skills. As the story progresses, they prove their worth during a big battle against an invading force. Their butterfly - like wings can be used for both quick evasion and powerful wind - based attacks.

One idea could be that Noodlehammer Naruto has some unique jutsu related to his 'noodlehammer' concept that he teaches to the original Naruto. This could lead to new ways of fighting enemies in the Naruto world. Another plot could involve them teaming up to face a powerful new villain who is immune to normal ninja techniques but is vulnerable to the strange powers of Noodlehammer Naruto.

One idea could be that the Star Trek crew discovers a new planet where magic exists instead of advanced technology. They have to learn to interact with the magic - for example, the teleporters might malfunction in the presence of magic fields and they need to use magical portals to get around. Another could be a character from the Star Trek universe getting magical powers and having to deal with the moral implications, like whether to use it for the good of the Federation or for personal gain.

One idea could be Boruto getting transported back in time and meeting a young Naruto. He could then help Naruto avoid some of the early hardships he faced, but also realizes that those hardships made Naruto who he is. Another could be Naruto and Boruto switching bodies for a day, which would lead to humorous situations as they try to navigate each other's lives. A third idea might be that Boruto discovers a hidden power within himself by training with Naruto in a special dimension where time moves differently.

One idea could be that Ichigo and Naruto are transported to a strange new dimension where they have to work together to find their way back home. They start by comparing their skills and learning from each other. For example, Naruto could teach Ichigo some of his shadow clone techniques, while Ichigo shows Naruto how to use his zanpakuto more effectively.

In some fanfictions, they could meet during a time - travel incident. Naruto from the present meets Naruko from the past or vice versa. They then exchange knowledge about the future or past events, which changes the course of their own timelines. This could lead to some really interesting character development as they both try to adapt to the new information and how it affects their relationships with their friends and family.

Maybe Kagome is mistaken for a new ninja from a far - off land. She has to quickly learn the ways of the ninja while also trying to find a way to return to her own time. Naruto could be the one to help her adapt and in the process they learn from each other's unique abilities.

In some fanfictions, they meet in a situation where Sasuke has lost his memory. Naruto then takes it upon himself to help Sasuke regain his memories and in the process, they go on various adventures together, facing different challenges that test their bond all over again.
