Perhaps a story where an angel blade is passed down through generations in a family. Each generation adds a new chapter to the blade's story. The current wielder discovers that the blade has a connection to an angelic prophecy. They must then embark on a journey to fulfill the prophecy, facing many trials and temptations along the way.
A plot could revolve around a group of heroes who use angel blades to fight against a new, powerful dark force. They have to discover the true potential of the angel blades and how to combine their powers to defeat the enemy. For example, they might find that when all the blades are united, they can open a portal to a dimension where the dark force originated, allowing them to face it on its home ground.
You could write a fanfiction where the Angel Blade has a mind of its own. It communicates with the wielder in a mysterious way, guiding them towards a greater purpose. The story could then revolve around the wielder trying to understand the blade's intentions, while also dealing with external conflicts like battles against dark forces and political intrigue within their own group.
A plot could involve Angel protecting Willow from a group of vampire hunters who mistake her for a dark witch. Along the way, they develop a deeper understanding of each other and their respective roles in the fight against evil. They might also discover a long - lost prophecy that involves both of them and has to do with saving the world.
A great plot idea could be that the shotgun the angel has is actually a cursed weapon. The angel has to figure out how to break the curse without losing the weapon's power. Or perhaps the fanfic could center around the angel's relationship with other celestial beings. They might not approve of the angel's violent methods with the shotgun and try to stop the angel from using it. This could lead to a conflict within the celestial realm.
One idea could be that an angel and a devil are forced to work together to save the world from a greater evil. They start off hating each other but gradually learn to respect and even care for one another.
One idea could be that an unknown entity with angelic powers emerges in the Naruto world during a time of great turmoil. This entity could initially be seen as a threat but later turns out to be a force for good, helping Naruto and his friends in unexpected ways. For example, it might use its 'angel of darkness' powers to purify the corrupted chakra in some of the villains, turning them into allies.
One idea could be a story where the character with blade arms has to protect a hidden village from a new and powerful enemy. Maybe they use their unique blade arms to fend off attacks and discover a secret about their origin in the process.
Perhaps in the fanfic, Alice Angel has lost her memory. Henry, who has some knowledge about the strange place they are in, tries to help her regain her memories. Along the way, they discover secrets about the place and their own pasts. Their relationship grows as they rely on each other for support, and Alice Angel starts to see Henry in a new light, different from how she might have perceived others before.
One idea could be that a Dark Angel character somehow enters the Harry Potter world and teams up with Voldemort, creating new and dangerous dark magic. Another could be a Hogwarts student discovers they have Dark Angel powers and has to struggle with whether to use them for good or be tempted by the dark side. A third idea is that the Dark Angel realm and the wizarding world are connected through a long - forgotten spell, and characters from both worlds must work together to close the connection before chaos ensues.
A possible plot could involve a Dark Angel being a long - lost relative of a powerful Star Wars character. For example, if they were related to a Jedi, they might struggle with their own dark tendencies while also trying to fit into the Jedi way. Or if related to a Sith, they could be the key to a new power or prophecy within the Sith hierarchy.
One idea could be exploring the lives of the characters in the afterlife world after achieving their initial goals. For example, they could start new projects or relationships. Another could be a time - travel twist where they go back to their past lives and try to change things. Maybe they find a new enemy or mystery to solve in the afterlife.
