I'm not sure specifically if there is a fanfiction exactly about Camie Utsushimi being pregnant. There are so many fanfiction platforms and a vast amount of content out there. You could try searching on popular fanfiction websites like Archive of Our Own or FanFiction.net to see if such a story exists.
One interesting plotline could be Deku having to face off against his classmates in a series of challenges that test not only their quirks but also their teamwork and strategic thinking. Maybe there's a misunderstanding that leads to the conflict.
Here is a simple toga himiko camie oc fanfic: In the bustling city of Musutafu, there was a new student named Camie. She was a bit of an outcast with her own unique style. One day, she bumped into Toga Himiko. Toga was intrigued by Camie's carefree attitude. They started to hang out more and more. Camie showed Toga her favorite spots in the city, like the hidden cafes and rooftops. As they spent time together, they realized they had more in common than they thought, and a strong friendship began to form.
Deku himself is likely to shine. Given his powerful quirk and his growth throughout the main series, he'll surely put up a great fight against his classmates. Bakugo could also shine as he's always been in competition with Deku and has a very strong quirk.
One interesting aspect could be the different interpretations of the characters' powers. In fanfiction, the author might explore new ways Deku uses his One for All ability against Overhaul's powers. It can also show different battle strategies that might not be in the original manga or anime.
You can try looking on fanfiction websites like Archive of Our Own (AO3) or FanFiction.net. These platforms usually have a wide variety of fanfictions, including ones related to 'Deku vs Overhaul'. Just use their search functions to find what you're looking for.
A more emotional idea would be a story where Camie has lost her memory. Toga Himiko finds her and tries to help her remember who she is. Along the way, they discover secrets about each other and their pasts, strengthening their bond.
One possible plotline could be that Camie discovers she's pregnant unexpectedly and has to deal with the reactions of her friends and family. Maybe some are supportive, while others are shocked or disappointed.
The main differences are in their expressions and some minor details of personality. In the manga, Deku might seem a bit more intense, while in the anime, he's sometimes presented a bit softer.
Deku might be completely shocked at first. Since Bakugou has always been so aggressive towards him, he would never expect such a confession. He might just stand there, mouth agape, not knowing what to say.
