One interesting plot is the exchange of combat techniques. The Power Rangers could teach the Avengers their martial arts - based fighting styles, while the Avengers could show the Rangers how to use their high - tech gadgets more effectively in combat.
Another great plot is a universe - merging scenario. Due to some sort of cosmic event, the universes of the Power Rangers and the Avengers start to blend. This means that the Rangers have to deal with the Avengers' villains in their own cities, and the Avengers have to face the Rangers' enemies. The two teams then must find a way to separate the universes again while also dealing with the new threats that this situation has created. It would be a great opportunity for character development as they adapt to the new and strange situations.
A fanfiction plot could be about a new threat that is specifically targeting the Omnitrix and the Power Rangers' power source. Ben and the Rangers have to figure out how the enemy is doing this and stop them. Along the way, they discover a hidden connection between the two power systems that was unknown before. There could be some character development for both Ben and the Rangers as they struggle to protect what they hold dear.
One idea could be a story where a new ranger from a different planet joins the SPD team. They have unique powers that the others don't, and at first, there's some tension as the team has to adjust to their new teammate. But eventually, they all work together to defeat a powerful new villain.
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.
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.
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.
A fanfiction could focus on a character from each group being transported to a strange new dimension. For example, Iron Man from the Avengers, Batman from the Justice League and the Red Ranger from Power Rangers. They must work together to find a way back home while also dealing with the threats in this new world. This would allow for interesting character interactions as they come from very different backgrounds.
In some fanfiction, there might be a story where the Power Rangers and the Avengers have to team up to fight a common enemy that is far more powerful than any they've faced before. This could involve a lot of strategy planning and combining of different fighting styles. Maybe the Rangers' martial arts skills blend with the Avengers' more brute - force or long - range attacks.
