One idea could be a demon OC who was once a human but was cursed into becoming a demon. This demon could be trying to find a way to break the curse while interacting with the main Gravity Falls characters. For example, they might befriend Dipper and Mabel and the trio could go on adventures together to find a magical artifact that could reverse the curse.
Think about the OC's backstory when designing them. If your demon OC was born from a magical experiment gone wrong, they might have some strange physical features like extra eyes or tentacle - like limbs. Or if they were once a forest spirit corrupted into a demon, they could have parts of their body that resemble tree bark or leaves. Combine elements from different sources in Gravity Falls and your own imagination to make a truly one - of - a - kind design.
One interesting Gravity Falls OC fanfiction could be about an OC who has the power to control time and how they interact with the main characters like Dipper and Mabel. They might use their power to prevent certain disasters in Gravity Falls or to gain knowledge from different time periods.
To create a great plot for a Gravity Falls male OC fanfiction, consider the setting. Gravity Falls is full of strange and wonderful places.

It can lighten the mood during tense situations, like when dealing with the supernatural threats in Gravity Falls.

I'm not sure if there is a specific 'Naruto and Wendy Romance' in Gravity Falls fanfiction. Gravity Falls has its own unique set of characters and storylines, and Naruto is from a completely different anime. While fanfiction can be very creative and cross - over in unexpected ways, it's not a common or well - known combination within the Gravity Falls fanfic world.
