A third idea could be that the Time - Turner from 'Harry Potter' gets mixed up with the time - traveling technology of 'Legends of Tomorrow'. This causes all sorts of chaos as spells start to affect the time - ship and the Legends' equipment, and the wizards are confused by the advanced technology. The two groups have to work together to fix the mess and set time right again.
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.
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 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.
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.
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.
I think Hermione would be really interesting. She's so intelligent and resourceful in the 'Harry Potter' world. In a fanfiction with 'Legends of Tomorrow', she could use her vast knowledge of magic to help the Legends understand and deal with magical threats they encounter during their time - traveling adventures. She might be able to figure out how to combine magic with their technology in ways no one else could.
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 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 interesting idea in 'Harry Potter' fanfiction is the concept of alternate universes. For example, a fanfic might explore what would happen if Harry was sorted into Slytherin instead of Gryffindor. This could lead to a completely different set of relationships and storylines. Another idea could be time - travel fanfics where characters go back in time to change certain events in the wizarding world's history. It adds a whole new layer of complexity and intrigue to the original story.
Rather than seeking sex - related fanfiction, I would suggest exploring the rich lore, character development, and exciting adventures in Legends of Tomorrow through legitimate fan communities. They usually offer engaging stories, in - depth analyses of characters, and creative interpretations that are more family - friendly and in line with the spirit of the show.
