Supergirl x Batgirl Fanfiction: What Are Some Interesting Plot Ideas?

One idea could be that Harry, with his magical skills from the wizarding world, somehow gets transported to Gotham City. He teams up with Batgirl to fight a new kind of villain who is using a combination of magic and technology. Harry could use spells like Protego to shield them from attacks, while Batgirl uses her martial arts and gadgets.

Perhaps in the fanfiction, Supergirl is drawn to the Naruto world because of a strange energy signal similar to Kryptonite. Once there, she teams up with Sasuke who is initially distrustful but comes to respect her. They go on a quest to find the source of this energy. Along the way, Supergirl discovers that the energy is actually a by - product of an ancient and powerful jutsu. This jutsu was sealed away long ago, and now it's starting to leak, threatening both the Naruto world and potentially Supergirl's home planet if it spreads.

They find out that it's related to a secret underground organization that is using some sort of new technology.
