A more character - centered plot could be about the relationships between the Rangers. Like a story where Emily struggles with her feelings for Kevin, and how this affects their teamwork as Power Rangers. This could add an interesting layer of drama to the fanfiction.
A great plot might involve the Black Ranger getting lost in a different dimension while on a mission. In this dimension, he has to adapt to new rules and powers while trying to find his way back. He could meet new allies or face enemies that are unique to that place. Also, a plot about the Black Ranger having to train a new recruit who has a lot of potential but also a lot of recklessness could be interesting.
In a fanfiction scenario where Emily is kidnapped, perhaps the kidnappers are after some special power she has that she doesn't even know about yet. The Power Rangers would then have to not only rescue her but also figure out what this power is and how to protect it. Maybe they'd discover some ancient scrolls that give them a clue about her power.
Well, one interesting plot point could be the development of relationships between the Power Rangers. Their bonds might strengthen not only in their fight against evil but also in the context of love. For example, a Ranger might discover new feelings for a teammate during a particularly tough battle, adding an emotional layer to their story.
Some fanfictions also explore a crossover with the Transformers. Imagine the Power Rangers Samurai working alongside the Autobots or Decepticons. It creates a really unique and exciting universe where two very different types of heroes and villains interact. There could be epic battles and interesting team - up strategies in these crossovers.
An interesting plot for Power Rangers OC fanfiction could be an OC who starts off as a villain's minion but then has a change of heart. This OC might be forced to do the villain's bidding at first, but through interactions with the Power Rangers, they see the error of their ways. They could then use their knowledge of the villain's plans to help the Rangers. Maybe this OC has a special ability that is crucial in defeating a major villain in the end.
One plot idea could be a baby Power Ranger discovers their powers early. For example, the baby might accidentally activate their morphing ability while playing with a shiny object that turns out to be related to their Ranger powers. Another could be that the baby is the key to saving the Power Rangers from a new villain who has a weakness only the baby can exploit. Maybe the baby has a special power of innocence that can counter the villain's dark magic.
One idea could be a female Power Ranger who has the ability to communicate with animals and uses this to gain an edge in battles. For example, she might get help from a group of eagles to spot approaching enemies from afar.
One idea could be a story where a new ranger has to hide their identity as a ranger from their family who are against any form of superhero activity. It adds a layer of drama and secrecy.
One idea could be exploring the backstories of the Power Rangers before they joined the team. For example, how did they discover their potential? Another could be a time - travel plot where they go back to a crucial moment in the history of their planet or the Power Rangers as a whole. Maybe they could meet their predecessors and learn from them.
One interesting crossover could be the wizards from Harry Potter using their magic in the world of the Power Rangers Samurai. For example, Hermione could use her knowledge of spells to help the Power Rangers in a battle against a powerful enemy that combines dark magic and the forces the Rangers usually fight.
