One possible storyline could be that Hiro Okamura uses his technological skills to create a device that can enhance Power Girl's powers even further. This could lead to them teaming up to fight a powerful villain who is threatening the city.

But as they get to know each other better, they realize they can complement each other's abilities and become friends and allies.
Perhaps in the fanfic, Hiro Okamura discovers a way to travel to Power Girl's home dimension. There, he helps her deal with a threat that her own world's technology can't handle. This could involve Hiro's unique knowledge of robotics and advanced engineering. Or it could be a story where Power Girl is injured and Hiro has to use his tech to keep her alive while she heals, and during this time, they develop a deep bond.
Hiro Okamura's technological powers could enhance Power Girl's abilities. For example, he could create a power - enhancing suit for her.
One possible storyline could be Hiro struggling with his new - found feelings for Baymax.

For example, Hiro could have dreams about Baymax in a more romantic context and then have to come to terms with his feelings.
One possible storyline could be a team - up against a powerful new villain in Gotham. Power Girl's super - strength and flight combined with Batman's detective skills would make for an exciting adventure. They could start off not trusting each other fully, with Batman being cautious of Power Girl's more brash and powerful approach, but as the story progresses, they learn to work together effectively.
Another idea is that Hiro is influenced by a dark force or a villain who convinces him that the world needs to be 'fixed' in a more extreme way. He might then create dangerous and unregulated technology that starts to cause chaos in San Fransokyo. He could see himself as a sort of anti - hero, believing his actions are for the greater good when in reality they are causing harm.
Perhaps there could be a story where Baymax starts to develop more human - like emotions and he and Hiro have to deal with the implications of that. Hiro might help Baymax understand these new feelings while also learning more about himself in the process.

A storyline could be that Katy helps Shawn discover his family roots. Since Katy is a mother figure, she might be interested in Shawn's past and help him dig into his family history. This could involve going to different places, meeting old relatives or friends of his family. Or, they could be in a situation where they have to pretend to be a couple for some reason. Maybe to help out a friend who is hosting an event where only couples are invited. This would lead to some awkward and funny moments between them as they try to act like a real couple. Also, they could team up to solve a mystery in their neighborhood, like a series of strange happenings around the local park.
One possible plot could be that as a girl, Hiro might face different challenges in the world of robotics. Maybe she has to work harder to be taken seriously in a male - dominated field.
