Some fanfictions might explore the Black Ranger's family background more deeply. For example, what if he discovers that his family has a connection to an ancient evil that he now has to fight? Or perhaps a story where the Black Ranger loses his powers temporarily and has to rely on his wits and martial arts skills to still contribute to the team. He could also have an adventure where he teams up with a former Ranger from a different generation.
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.
One idea could be the Black Ranger getting lost in a parallel dimension. He has to use his skills and wits to find his way back home while facing new enemies and making unexpected allies. Another plot could involve him losing his powers temporarily and having to rely on his martial arts training to protect the city.
The Pink Ranger could be an interesting character to pair with the Black Ranger. Maybe they have a love - interest kind of relationship where their different personalities clash at first but then they grow to understand and care for each other. Also, a villain who has a personal vendetta against the Black Ranger could be paired with him in a story. This would create a lot of tension and conflict, making for an exciting plot.
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.
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.
One plot idea could be that your OC is a long - lost Samurai who has been in hiding. They come back to help the current Rangers when a new, more powerful enemy emerges. Another idea is that your OC has a power that the villains want to steal, so the Rangers have to protect them while also dealing with the threat.
One plot idea could be the female red ranger having to prove herself in a male - dominated ranger team. She could face discrimination at first but then show her unique skills in combat and leadership, winning over her teammates. Another idea is that she discovers a new power source that is related to her femininity, like a power that is linked to the power of nature and female intuition. Maybe she has to go on a solo quest to master this power while the rest of the team is dealing with a different threat.
Another idea is a character swap. Picture Naruto as a Power Ranger Samurai. He would bring his ninja skills and determination to the team. His Rasengan could be transformed into a special attack for his Samurai Zord. Or, a Power Ranger Samurai could be sent to the Naruto world and have to learn ninja techniques to survive and help the village.
She could be from a hidden clan. Maybe her clan was in charge of protecting a powerful and ancient artifact. But when the Nighloks started getting more aggressive, her clan decided it was time for her to join the Power Rangers. Her skills with the katana, which she learned from her clan's strict training regime, would be a great asset to the team.
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.
One popular trope is the samurai ranger facing a powerful ancient evil. This often involves a lot of intense battles and the ranger having to draw on their inner strength and the power of their samurai heritage. Another is the development of unique relationships within the ranger team, like a mentor - mentee relationship or a deep friendship that helps them overcome challenges. And there's also the trope of the ranger unlocking new powers or forms, which adds an exciting element to the fanfiction.
