There could be a Flashpoint Crossover Fanfiction that focuses on the Flashpoint villains crossing over into a more stable DC universe. The villains would be out of their element, and seeing how they adapt and cause chaos in a new world would be really engaging. Their motives might change as they encounter new challenges and heroes.
One interesting plot idea could be that the Flashpoint event somehow creates a rift that pulls characters from Supernatural into the Flashpoint universe. For example, Sam and Dean Winchester could be chasing a demon that escapes into this new, altered reality. They'd have to deal with the different laws of physics and the presence of superheroes like Flash. Another idea is that a powerful supernatural being from the Supernatural world causes the Flashpoint event in the first place, perhaps as part of a larger plan to reshape all of existence. And a third idea could be that a character from Flashpoint, like Iris West, has some latent supernatural ability that is awakened by the presence of the Winchester brothers, and they have to figure out how to control it before it causes chaos in both their worlds.
Well, for one, Harrison Wells from Flashpoint and Castiel would be really interesting. Wells is a brilliant scientist, and Castiel is an angel. Wells could be intrigued by Castiel's otherworldly nature and try to study him, while Castiel could use Wells' knowledge to better understand the science - based threats in the Flashpoint universe. Another cool combination would be Felicity Smoak from Flashpoint and Rowena from Supernatural. Felicity is a tech - genius, and Rowena is a powerful witch. They could either be rivals, with Felicity trying to use her tech to counter Rowena's magic, or they could team up and create some really powerful spells or gadgets. And then there's Oliver Queen from Flashpoint and Sam Winchester. Oliver is a skilled archer and fighter, and Sam is a hunter. They could share their combat techniques and knowledge, and together they could take on some really tough opponents in both the Flashpoint and Supernatural worlds.
One interesting concept could be the alternate character developments. In Flashpoint Fanfic, characters might have different backstories and motivations compared to the original. For example, a hero could start as a villain or vice versa, which creates a whole new dynamic for the story.
When writing Flashpoint Crossover Fanfiction, it's important to stay true to the essence of the characters while also exploring new aspects. Don't be afraid to deviate a little from the original storylines to create something fresh. And of course, write in a way that engages the readers, with good pacing and description.
Another plot development could be that Flashpoint Batman tries to convince the regular Batman to change his ways. He might see the regular Batman's methods as too soft or ineffective. This could create a lot of internal conflict for the regular Batman as he questions his own beliefs and methods in the face of this alternate - self's criticism.
One idea could be exploring how the Flashpoint Paradox affects the relationships between the Young Justice team members. For example, some friendships might be strengthened while others could be strained due to the altered timeline.
I'm not entirely sure specifically what the top stories in Flashpoint 2020 were without more context. It could be about various events like political happenings, scientific breakthroughs, or cultural phenomena. Maybe it included stories about the start of the COVID - 19 pandemic which was a major global event in 2020.
Some fanfictions could be about how the events of Flashpoint in the 'Watch Flashpoint' scenario impact the Young Justice characters' backstories. It could be really interesting to see how their origin stories change in this new context.
One popular 'audreyv flashpoint fanfic' might be the one that focuses on the character development of Audrey in the Flashpoint universe. It could explore her relationships with other characters in a new and interesting way.
One interesting Talion Crossover Fanfiction could be a crossover with 'The Lord of the Rings' characters other than the ones already in the original game. For example, Talion interacting with Aragorn in a different time or place. It could explore how their leadership styles compare and contrast.
