One idea could be that Barry Allen accidentally runs so fast that he breaches the multiverse and ends up in the Harry Potter world. He could use his super speed to help Harry and his friends in their battles, like quickly disarming Death Eaters.

They could learn from each other's skills, Harry teaching Barry about magic and Barry teaching Harry about science and speed.
Perhaps in the fanfiction, Barry Allen discovers that his speed force has a connection to the magic in the Harry Potter universe. He could be drawn to Hogwarts where he meets Harry Potter. They find out that they are both destined to stop a powerful dark force that is threatening both the wizarding world and Central City. Barry's ability to move at super - speed could be used to protect Hogwarts from attacks, while Harry's magic could help Barry deal with magical threats in his own world.
The combination of two very different universes. Harry Potter has magic, wizards, and a complex magical society, while Barry Allen is a superhero with super - speed. Merging these two concepts can lead to really unique and unexpected storylines.
Well, an interesting plot might be that Barry and Kara discover a connection between their powers at a deeper level. For example, their powers are linked to an ancient energy source.

One plot idea could be that Oliver, in his yandere state, becomes overly possessive of Barry. He starts to interfere in Barry's superhero activities, believing he can protect him better.

This could lead to a conflict where the League has to decide how to deal with Oliver while also protecting Barry from his over - the - top affections.
One plot idea could be that Fem Barry Allen, with her super - speed abilities, and Oliver Queen, the skilled archer, team up to take on a new threat in Star City.

Another idea is that they start off as rivals, competing to see who can protect the city better, but gradually fall in love as they realize they can achieve more together. And a third plot could be that they get transported to an alternate dimension where they have to rely on each other completely to find their way back home while also facing off against versions of themselves from that dimension.
Maybe the OC is from a parallel universe where the rules of the Flash's powers are different.
