I also like 'Finnick's Secret Love'. Here, the OC has a mysterious past which adds an extra layer of intrigue to the story. The way the author develops the relationship between Finnick and the OC is really engaging, with a lot of tender moments and some great twists along the way.
One popular 'The Hunger Games Finnick fanfiction' is 'Finnick's Redemption'. It delves deep into Finnick's past traumas and his journey towards healing. The author does a great job of portraying his complex character and his relationships within the Hunger Games universe.

To write a good Hunger Games Finnick OC fanfiction, you should do in - depth research on the Hunger Games universe. Know the rules, the different districts, and the overall atmosphere. For your OC, give them distinct physical and personality traits. For instance, your OC could have a scar from a past accident that symbolizes their strength. When it comes to Finnick, explore his relationships with other characters in the original story and how your OC fits into that web. Also, use vivid language to describe the action and emotions. For example, when Finnick and the OC are in a fight, describe the fear in their eyes and the adrenaline in their veins.
Another theme is survival. They have to not only survive the physical threats like the Games but also the emotional and mental challenges that come with their relationship. It's about how they support each other to stay alive in a cruel world.
One great Finnick OC fanfiction is 'Finnick's New Beginning'. It creates a really interesting original character who teams up with Finnick in the arena. The story is full of action and the relationship between Finnick and the OC is developed really well.
Annie Cresta would be an obvious choice. Their relationship in the original story was deep and complex, so exploring it more in fanfiction could be great. Another good character to pair him with could be Katniss Everdeen. They both had strong personalities and were part of the rebellion. Their interactions could lead to some interesting storylines. Peeta Mellark could also be a good pairing. Finnick could help Peeta during the Games or in the post - Games situation, and their different skills and personalities could create some engaging scenes.
One great fanfiction could be about Finnick and Katniss teaming up in the arena in a way that wasn't shown in the original books. They use their unique skills to outwit the Capitol's new and devious traps.
One great fanfiction could be 'Finnick's Redemption'. It delves into Finnick's life after the games, how he copes with the trauma. Another is 'Finnick and the Lost Years' which fills in the gaps of his past that the original series didn't fully explore. And 'Finnick's New Hope' where he becomes a symbol of change in Panem.
Fanfiction.net is a good bet. Just search for 'Finnick' in the Hunger Games section. Another option is Wattpad. Sometimes it has some really creative Finnick fanfictions. But be aware that the quality can vary more on Wattpad compared to the other two platforms.
There's also 'A New Hope in the Arena'. In this fanfiction, the original character brings a fresh perspective to the Games. The author does a great job of developing the character's relationships with the existing characters from the series. It's a story that really draws you in and makes you care about what happens to the OC.
