The Flash himself, of course. He is the central character and his ability to time travel is what drives most of the stories. Fans love to explore his different adventures through time.
Reverse - Flash is also very popular. His complex relationship with the Flash, especially in a time - travel context, adds a lot of drama. He might go back in time to change things to his advantage or to mess with the Flash's life.
Some Flash time travel fanfics play with the idea of time travel via dreams. Barry Allen could enter a dream - like state where he experiences different timelines. It's an interesting take as it blurs the line between reality and the subconscious.
The Flash's time travel to the future in fanfiction is really interesting. Firstly, his ability to move through time can expose him to future technologies and civilizations. He could bring back knowledge of these things to the present. Secondly, his actions in the future might be misinterpreted by the people there. They could see him as a threat and try to stop him. This would create a conflict that he has to resolve while also dealing with the implications of his time travel on the future.
First, understand the Flash's time travel mechanics in the original source. Then, come up with a unique time period or event to send the Flash to. For example, you could send him back to the Wild West. Next, think about how his actions in that time will affect the present or future. Keep the story focused on the Flash's character growth through his time - traveling experiences.
One great aspect of Flash time travel fanfiction is the infinite possibilities it offers. Writers can explore different timelines, fix past mistakes, or even create alternate universes. For example, a popular plot could be Barry Allen going back in time to prevent a major villain from ever getting their powers. It allows for creative interpretations of the characters and their relationships.
One common theme is the idea of fixing a future gone wrong. The Flash might see a desolate future and go back in time to prevent certain events from happening. Another theme is the discovery of new powers or abilities in the future that he then tries to harness in the present.
Time lords from Doctor Who are also quite popular in x time travel fanfiction. Their natural ability to travel through time and space makes them a natural fit.
