Maybe there's a spell in the Harry Potter universe that somehow calls Kara Danvers to Hogwarts. She then has to adjust to the magical rules while also teaching the wizards and witches about her own kind of powers. For example, she could show them how to use super - strength in a non - magical way, like building things faster. And in return, they teach her some advanced magic spells.
Another possibility is that Kara and Hermione become friends. Kara could introduce Hermione to some advanced technology from her world, while Hermione could teach Kara about the complex magic in the wizarding world. They could work together on some sort of project that combines science and magic, like creating a device that can detect dark magic using a combination of muggle technology and spells.
Kara Danvers could fit in as a sort of outsider - hero. She has powers that are different from magic, but she could learn to respect and work with magic. For instance, she might use her super - speed to quickly gather ingredients for potions or her heat vision to melt through locked doors in Hogwarts' secret passages.
Begin by creating a setting. Decide if the story will take place mainly in the wizarding world, in Kara's world, or in a new place that combines elements of both. Then, introduce your characters. Write about how Kara first encounters the wizarding world or how the wizards react to her presence. You can start with a scene that grabs the reader's attention, such as Kara crashing into Hogwarts during a Quidditch match.
One idea could be a story where Oliver Queen finds himself in Kara's universe by some sort of multiverse accident. He teams up with Kara to fight a common enemy that is causing chaos in both their worlds. Their different fighting styles, Oliver's more grounded archery and hand - to - hand combat and Kara's super - powered abilities, would make for an interesting dynamic in battles.

One possible scenario in such a fanfiction could be that Kara gets physically hurt during a fight against a powerful enemy while Lena is desperately trying to find a way to save her.

I'd recommend 'The Danvers Sisters' Journey'. It focuses on their growth as individuals and as sisters. It has some really heartwarming moments, like when they have late - night talks and share their deepest fears.
