A really cool Gokaiger fanfiction idea is one where they travel to different dimensions not just to find the Ranger Keys, but also to solve problems in those dimensions. They could end up in a dimension where the concept of time is broken and have to fix it while also dealing with local villains.
There could be a Gokaiger fanfiction that focuses on the backstories of each individual Gokaiger. For example, how they came to be chosen for the mission and what their lives were like before joining the team. This would give more depth to the characters and make the story more engaging.
One idea could be a crossover with the Power Rangers. The Gokaigers could team up with the Rangers to fight a common enemy that threatens both their universes. Maybe they start off as rivals, not understanding each other's ways, but then learn to work together as they realize the scale of the threat.
One interesting IT 2017 fanfiction could be about an alternate ending where the Losers' Club has different ways of defeating Pennywise. For example, they might use a different set of skills or items that are not in the original movie.
How about including characters from Sailor Moon? It would be really interesting to see the Gokaigers interact with the Sailor Scouts. Maybe they could learn some new strategies from the Scouts' magic-based attacks.
One possible plot is that the Lion Guard discovers some strange energy signatures that seem out of place in their world. These turn out to be related to the Gokaigers' power sources. As they try to figure out what's going on, the Gokaigers also detect a disruption in the balance of their power. They meet up and find out that a powerful enemy is trying to harness the combined power of both the Gokaigers' ranger powers and the magic of the Lion Guard's world. So, they have to put aside their differences and work together. The Lion Guard can use their natural abilities like Simba's roar, while the Gokaigers can use their mecha and ranger attacks to battle this new threat.
One interesting Ramattra fanfiction could be about his origin story. It might explore how he came to be and the events that led to his current beliefs and actions. Another could be a story where Ramattra forms an unlikely alliance with a hero he once considered an enemy, leading to a whole new adventure full of moral dilemmas and intense battles. There are also fanfictions that focus on his relationship with other Overwatch characters in a more personal, non - combat way, like his conversations and shared experiences with them.
One interesting Nightwish fanfiction could be one that explores the backstories of the band members in a fictionalized way. For example, it might create a story about how Tuomas Holopainen got inspired to write some of their most famous songs.
One interesting Shanks fanfiction could be about his early days as a pirate. It might explore his relationships with his crewmates back then.
One type of Annie 1982 fanfiction could be set in an alternate universe. In this universe, Annie could have different powers or abilities. For instance, she might be able to communicate with animals, which could lead to all sorts of new and exciting storylines. Another aspect could be that the fanfictions expand on the backstories of the characters, like delving deeper into Annie's past before she came to the orphanage, which can add more layers to the story.
Some 'Naruto' fanfictions are really cool. For instance, the ones that give Naruto new powers. Maybe he gets a power related to space - time manipulation that he has to learn to control. This can lead to really exciting adventures and battles. Also, fanfictions that rewrite the whole story from an alternate point of view, like from the view of the Akatsuki members, can be very interesting as it shows a different side of the 'Naruto' universe.
One interesting Watamote fanfiction could be those that explore Tomoko's growth in different social situations. For example, a fanfiction might focus on her joining a new club at school and how she overcomes her social anxiety there. Another could be about her making a real, deep friendship outside of her usual awkward encounters.
