What are the most interesting plot ideas in 'Mass Effect', 'Percy Jackson' and 'Naruto' fanfiction?

A possible plot is that in a mass harem fanfiction of Naruto and Percy Jackson, there is a competition among the harem members to gain the attention and affection of Naruto and Percy. This leads to some chaos and jealousy at first. However, Naruto and Percy work together to create a harmonious environment. They introduce their own cultures and values to the harem. Naruto shares the concept of ninja honor and Percy talks about Greek mythology and the importance of loyalty. As they do this, they also face external threats that require them to unite the harem and fight together.

One idea could be that Naruto is somehow transported to the Mass Effect universe and his unique abilities draw the attention of various female characters. They see his determination and power as something new and exciting, leading to a harem situation. For example, characters like Liara might be intrigued by his chakra abilities which are completely different from biotics in their world.

One idea could be that Naruto, with his unique abilities like the Rasengan and shadow clones, gets transported to the Mass Effect Andromeda universe. He could use his ninja skills to help the Pathfinder team in combat situations against the Kett or other enemies.

A possible plot is that a Mass Effect technology is introduced to the Naruto universe. Maybe a Mass Relay is found in the Hidden Leaf Village. This could lead to a whole new set of adventures as the ninja try to figure out what this strange technology is and how it can be used. Or, characters from both universes could be combined. Like a Turian with Sharingan abilities.

One idea could be that Naruto is somehow transported to the Mass Effect universe. He could use his ninja skills, like his shadow clones, in combat against the various alien species in Mass Effect. Maybe he teams up with Shepard and they learn from each other's combat styles.

One idea could be that Naruto somehow gets transported to the Mass Effect Andromeda universe. He might use his chakra powers in unique ways, like using Shadow Clones to outmaneuver the Kett. Another plot could involve Naruto befriending Ryder and teaching them about chakra, which then gives Ryder an edge in combat and exploration.

One interesting plot twist could be that Fem Shepard is actually related to a powerful clan in the Naruto universe. This could be revealed through some sort of genetic discovery. It would completely change her understanding of herself and her place in both universes. Another twist could be that Naruto discovers he has latent biotic abilities that are only awakened when he is in the Mass Effect universe. This would give him a whole new set of powers to explore and master, and also create a connection between him and the technology - based world of Mass Effect.

One interesting plot element is the power combination. For example, Naruto's chakra - based abilities combined with Percy's control over water as a son of Poseidon. It creates really cool battle scenes. Another is the cultural clash. The shinobi culture from Naruto and the demigod culture from Percy Jackson are very different. When characters from both worlds meet, there are misunderstandings at first, but then they learn from each other.

Another cool concept is the idea of a character with the Rinnegan being a biotic anomaly. Since biotics in Mass Effect are about manipulating dark energy fields, the Rinnegan's power to manipulate chakra could be seen as a parallel, and fanfictions might explore how this would change the perception and use of biotics in the Mass Effect universe. This could involve things like new biotic techniques or the character being hunted or revered for their unique abilities.

Perhaps a story where Percy and Natasha are both sent back in time to ancient Greece. There, they have to work together to change a certain event in history. Along the way, Percy gets to show Natasha his world of demigods and she gets to use her spy skills in a very different setting.
