Another plot could involve a Sister of Battle who is on a mission to retrieve an important relic that has been lost in a Guardsman - occupied area. A particular Guardsman becomes involved in her mission, either by accident or because he has some knowledge that could be useful. As they search for the relic, they face internal conflicts within their respective orders as well as external threats.
One plot idea could be that a Guardsman gets separated from his unit during a battle and is rescued by a Sister of Battle. They then have to work together to make their way back to safety while facing various enemies and challenges along the way. This could lead to a growing respect and friendship between them.
A great one often has well - developed characters. The Guardsman should have his own personality, whether he's a grizzled veteran or a fresh recruit. The Sister of Battle should also be a complex character with her beliefs and values. And the story should have an engaging plot, like a joint mission against a common enemy in the Warhammer 40k universe.
It can start with mutual respect. For example, the Guardsman respects the combat skills and religious fervor of the Sister of Battle, while the Sister respects the tenacity and loyalty of the Guardsman. They can then be forced into situations where they have to rely on each other, like being trapped in a war - torn area and having to fight their way out together. This shared experience can deepen their relationship.
You can start by looking on fanfiction websites like Archive of Our Own (AO3). There are often many user - generated stories in the Warhammer 40k category that involve Guardsmen and Sisters of Battle. Another option is to check out dedicated Warhammer 40k fan forums. Some fans might share their own fanfiction or recommend good ones there.
One idea could be that they are forced to team up during a chaos invasion. The Battle Sister's faith and the Space Marine's combat skills complement each other as they fight hordes of daemons. Maybe they start off distrusting each other, but as the battle rages on, they learn to respect and rely on one another.
Another plot idea is that the Salvatore sister is forced to team up with Katherine. Perhaps there's a new, powerful enemy in town that only their combined knowledge and powers can defeat. As they work together, the sister starts to see Katherine in a different light, not just as the villain the Salvatores always thought she was. This could create a complex relationship full of tension and unexpected alliances.
One idea could be that Naruto and his twin sister have a special bond that allows them to share chakra in unique ways. For example, when Naruto is in a tough battle and running low on chakra, his sister can transfer some of hers to him, even from a distance. Another plot could revolve around them both having a secret mission that only they are trusted with by the Hokage. This mission could be related to an ancient prophecy that involves the siblings.
One idea could be a trainer who discovers a new Pokemon with an extremely powerful and unique Battle Bond ability. For example, it could be a Pokemon that not only powers up but also changes form in a completely unexpected way when the Battle Bond activates. Another plot could involve a trainer who has a difficult relationship with their Pokemon. Through the development of the Battle Bond, they learn to understand each other better and become a stronger team. A third idea is a story set in a tournament where the Battle Bond becomes a crucial factor. Trainers have to figure out how to trigger it at the right moment to gain an edge over their opponents.
One idea could be to focus on a new Autobot character arriving at Autobot City just before the battle. This character could bring a unique skill or weapon that helps turn the tide of the battle in unexpected ways.
An interesting plot for a Transformers Battle Stars fanfic could be a competition between the Autobots and Decepticons. Not a battle, but a race to complete a series of challenges on a newly - formed planet. The winner would get exclusive rights to the planet's resources. This would force the two factions to use their skills and intelligence in different ways than just fighting. Another plot could involve a human - like race that the Transformers encounter. The Transformers have to decide whether to protect this race or use them for their own ends, which causes internal conflict within both the Autobot and Decepticon ranks.
Well, a cool plot for an MLP Battle Force 5 fanfic could be that there's a strange energy wave that disrupts both the MLP world and the Battle Force 5 world. The ponies and the Battle Force 5 members start having strange abilities or problems because of it. They then have to figure out the source of this energy wave, which leads them on an adventure across both worlds. Along the way, they learn about each other's cultures and strengths, and in the end, they manage to stop the energy wave and become friends. It could also involve some of the ponies learning to drive the Battle Force 5 vehicles in a really funny way.
