A really interesting fanfic in this genre is 'OC's Justice League Adventure'. In this one, the OC is not a typical hero. They come from a different dimension and have to learn the ways of the Justice League's Earth. It's full of humor as the OC makes mistakes while trying to fit in and also has some deep moments when they share their own world's problems with the League members.
There's also 'The Secret OC of the Justice League'. Here, the OC has been secretly helping the Justice League all along, but no one knows their true identity. The story unfolds as the OC's identity is gradually revealed, and there are many plot twists along the way. It's a great read for those who like mystery - filled fanfictions.
One great 'OC Justice League Fanfiction' is 'The New Hero Among Them'. It's about an original character with unique powers who joins the Justice League. The story focuses on how the OC adapts to the big - league environment and forms relationships with the well - known heroes. It has exciting action scenes where the OC's powers are put to good use against classic villains.
One common theme is the 'fish - out - of - water' story, like when an OC from a normal life suddenly gets thrown into the world of the Justice League. It creates a lot of opportunities for character growth and comedic moments as they struggle to understand the superhero world.
I highly recommend 'Justice League: The Lost Years'. This fanfiction delves deep into the backstories of the members. It's full of action, mystery, and some really cool alternate versions of their powers. It's a long read but definitely worth it.
The OC's personality can be very distinct. They could be extremely humorous and use that to lighten the mood during tense situations. This would be different from the more serious natures of some of the Justice League members like Batman. Also, they could have a strong moral code that is not exactly the same as the League's, which would lead to interesting discussions and interactions.
One of the best is 'Tower of Babel'. In this story, Batman's contingency plans against the Justice League members are stolen and used against them. It shows the complexity of the relationships within the team and how dangerous their powers can be when misused. It also delves into the trust issues among the heroes.
The OC shop owner could be a former member of a secret society that has knowledge about the Justice League's enemies. They use their shop as a cover while secretly helping the League by providing intel. For example, they overhear conversations from villains who visit the shop thinking it's just an ordinary place.
An OC (Original Character) villain in the Justice League universe could be really interesting. For example, let's call our villain 'Shadowcaster'. He has the power to manipulate shadows and create illusions within them. In the fanfiction, he could start by targeting the less - known members of the Justice League, like Hawkman. He'd use his shadow powers to make Hawkman question his own reality, causing chaos within the team as they try to figure out what's wrong with their comrade. This would draw the attention of the big guns like Superman and Batman, who then have to figure out how to combat a villain they've never faced before.
There's also 'The Dark Knight of the Future in the League'. This fanfiction focuses on Batman Beyond's unique perspective within the Justice League. It shows how his different set of skills, being more in tune with the future tech, can be both an asset and a source of conflict. It's not too long but packs a punch in terms of character development and action scenes.
The 'Justice League: Crisis on Infinite Earths' also involves time travel elements. The League has to deal with threats across different timelines and universes. They travel through time to prevent the destruction of multiple Earths. It's a complex and epic story that shows how the Justice League copes with the chaos of different time periods and realities.
The 'JLA: Year One' is also excellent. It details the early days of the Justice League. Batman plays a crucial role in bringing the team together. His detective skills and leadership, although a bit unorthodox at times, are vital for the formation of the iconic superhero team. It's a great story that gives insights into the relationships between the characters from the start.
One of the best is 'Tower of Babel'. In this story, Batman's contingency plans against the Justice League members are stolen and used against them. It shows the complexity of the relationships within the team and how dangerous it can be when their secrets are exposed.
