Well, one possible plot development could be Shepard using his/her new - found survivor status to unite different alien races even more closely. Maybe Shepard starts a new initiative for inter - galactic cooperation that was not possible during the war.
There could be Garrus. Since he's Shepard's close friend, he'd likely still be by Shepard's side, helping out in the post - war situation. Maybe they work together to take down any remaining threats.
In 'naruto after 4th war fanfic', a really cool plot development could be the integration of the tailed beasts into normal society. Since the war is over, the tailed beasts are no longer seen as just weapons. They might start to live among the humans, and some ninja could even form bonds with them outside of being jinchuriki. This would completely change the power dynamics and social structure of the ninja world. Also, there could be a plot where Naruto uses his new - found influence after the war to create a more unified ninja world, where villages share resources and knowledge more freely.
One idea could be exploring the backstory of the dragon commanders. Maybe how they were chosen and trained before they took on their important roles. Another could be a story where a dragon commander has to form an alliance with an unexpected group to save their land from a new, powerful threat.
One popular theme is romance. Many fanfics explore her relationships with other characters like Garrus or Kaidan in a more in - depth way. Another theme is her leadership, showing different aspects of how she commands the Normandy crew and makes tough decisions.
One common plotline could be Shepard having to adjust to the more bureaucratic and political aspects of being an admiral. For example, dealing with different alien species' political representatives in a more diplomatic way compared to when just a commander on the front lines. Another could be Shepard using their new rank to push for more far - reaching military strategies against the Reapers or other threats. Maybe Shepard has to oversee the training and deployment of new recruits, which was not as much of a concern when leading a small, elite team.
In some 'naruto is banished fanfic', one interesting plot could be Naruto finding a new hidden village that accepts him wholeheartedly. He might then train with unique jutsus there and form new alliances.
There could be a new friendship formed between characters that wasn't in the original. Maybe a character overcomes a major fear or achieves a personal goal.
One interesting plotline could be Bardock using his newfound chance at life to train and become an even stronger warrior. He might then use his power to protect planets that were previously doomed in the original story. Another could be Bardock interacting with characters he never got to meet before, like certain Earthlings, and learning about their ways of life and fighting styles.
One idea could be to cross Supreme Commander with a sci - fi RPG like Mass Effect. The Supreme Commander's advanced technology could be introduced into the Mass Effect universe, causing a stir among the various species. Maybe the protagonist has to figure out how to use the Supreme Commander's strategic resources to fend off a new Reaper threat.
In 'naruto things change fanfic', one interesting plot development could be the altered relationships between characters. For example, Naruto might form unexpected alliances earlier in the story, which changes the whole dynamic of his training and growth.

They might have more complex motives that deviate from the original Naruto storyline, leading to more nuanced confrontations.
