Well, a cool plot for such fanfiction could be an OC who is an outcast from a secret society in time. This society has its own rules about time travel and the OC breaks them, so they are on the run. They end up joining the Legends as a way to hide from their pursuers. Another plot could be an OC who has a power to sense when time is about to be disrupted on a large scale. This ability leads them to the Legends, and they have to work together to prevent a cataclysmic time - related event. Also, an OC who can transform into different historical figures, which both helps and hinders the Legends during their missions.
An interesting plot for DC Legends of Tomorrow OC fanfiction could involve an OC who is a long - lost relative of one of the main characters. This OC might have been hidden away in time for some reason and now resurfaces with unique powers. Maybe they have the ability to communicate with past versions of themselves, which gives them an edge in understanding time - related problems. Or perhaps an OC who is a time - displaced artist. They use their art to record and sometimes even change events in time, causing the Legends to have to deal with these artistic alterations.
A possible plot is that a powerful enemy from the future in the Legends of Tomorrow timeline discovers the power of chakra in the Naruto universe. So, they travel back in time to try and harness it for their own evil purposes. The Naruto characters, along with the Legends of Tomorrow crew, must then join forces to stop this enemy. This would involve the Legends of Tomorrow team learning about ninjutsu and the Naruto characters learning about time - travel technology.
One idea could be a crossover where the demigods from Percy Jackson meet the time - traveling heroes of Legends of Tomorrow. They could team up to stop a threat that spans across different timelines and mythologies. For example, a powerful ancient monster has been awakened in the future and is using time - travel to gain more power from the past. The demigods' powers and the time - travel abilities of the Legends would be combined to fight this foe.
Maybe there's a powerful magical artifact that has the ability to destroy both the Arrowverse and the timeline that the Legends protect. The two teams join forces to find this artifact before it falls into the wrong hands. They face numerous challenges and battles along the way, and some characters might have to make sacrifices to save the day.
One interesting storyline could be the Legends teaming up with characters from other DC shows in a different timeline. For example, they might meet the Justice League from an alternate reality where the rules of time and space are very different. This could lead to some really cool battles and power struggles as they try to figure out how to get back to their own timeline.
One title could be 'The Male OC's Adventure in Legends of Tomorrow'. It's simple and straightforward, clearly indicating that the story will be about a male original character in the Legends of Tomorrow universe.
One idea could be a crossover where the characters from 'Harry Potter' visit the world of 'Legends of Tomorrow'. They could team up with the Legends to fight a common magical - time - related enemy. For example, Voldemort could be trying to manipulate time to his advantage and the combined forces have to stop him.
An interesting plot could involve an OC who has the power to communicate with animals. In the story, they use this power to gather intel on the villains' plans. The animals could provide information that the Avengers wouldn't be able to get otherwise, like the location of a hidden lair or the movements of enemy troops.
One idea could be to explore an alternate timeline where the Legends accidentally change a major historical event in a way that creates a dystopian future. They then have to figure out how to fix it without making things worse.
First, give your OC a unique power. For example, the power to control the speed of time in a small area. Then, think about their backstory. Maybe they were an experiment gone wrong in a time - traveling lab. Their personality should be distinct as well. They could be a bit of a loner because of their strange power, but also have a strong sense of justice. Also, consider their goals. They might want to find a way to reverse the effects of the experiment on themselves.
Fanfiction often contains inappropriate or non - canon content, and 'DC Legends of Tomorrow' is a great show that should be focused on its official storylines, characters' development, and the amazing time - traveling adventures. So, I don't recommend seeking out sex fanfiction related to it.
