Characterization is key. The way Gale is portrayed should be in line with his original character in the Hunger Games series. The OC should also be well - developed, with a clear backstory and motives. For example, if the OC is from a different district, their district's culture and how it shapes them should be explored. Another element is the relationship between Gale and the OC. It should be believable and add something new to the story.
When it comes to Hunger Games fanfic about Peeta and Gale, a lot depends on the writer's perspective. Some might write Peeta as the underdog who finally gets his happy ending, while Gale is the one who loses out on Katniss. Others may explore a world where Peeta and Gale become friends, despite their differences. They could bond over their shared experiences in the Hunger Games, like the loss of friends and the struggle against the Capitol. This can make for some really interesting fanfic storylines.
I've heard of a fanfic called 'Gale and the Mysterious OC'. In this story, the OC has some unique abilities that draw Gale in and they embark on a journey that's both dangerous and full of self - discovery. It's a well - written fanfic that gives a lot of depth to Gale's character. Another one is 'Gale's Redemption through the OC', which shows Gale's journey towards redemption with the help of the OC, exploring themes of forgiveness and second chances in the context of the Hunger Games universe.
One common theme is friendship. Gale has a strong personality, and when combined with an original character, their friendship can be explored in different ways, like how they support each other in the harsh world of 'Hunger Games'.
Peeta is often seen as the kind - hearted and soft - spoken one in fanfic. He might be written as having a deep understanding of art and culture, which he uses to comfort himself and others. Gale, in contrast, is usually the tough guy. He is more action - oriented and may be shown as being more impulsive. For example, in some fanfics, when there is a threat, Gale is the first to jump into action while Peeta thinks about the consequences.
One interesting storyline could be Gale and Peeta teaming up after the games. They realize that the Capitol has pitted them against each other for too long and decide to work together to bring about real change in the districts. They use their different skills, Gale's hunting and survival skills and Peeta's charm and way with words, to start a rebellion from within.
Gale would likely become more hardened. The pain of being whipped would make him more determined to fight against the Capitol. He might become less trusting of others, fearing that they could be informants who led to his whipping. For example, he could be more cautious around people he used to consider friends.
