The character of Rocket Raccoon is a complex and interesting one. He is known for his sarcastic humor and his mechanical expertise. While the franchise is inclusive in many ways, there is no story arc that has been presented as a gay story for Rocket. His character development is more about coming to terms with his own identity as a creation and finding his place among his friends, rather than any sexual - orientation - based storyline.
Your OC could be a mechanic from a different planet who idolizes Rocket. They join the Guardians after impressing them with their skills in fixing a crucial piece of the Milano. This could lead to a story about the OC learning the ropes of being a Guardian, getting into arguments with Rocket about the best ways to upgrade their weapons and ships, and also developing relationships with the other members of the team. It could also involve a plot where the OC has to face their own fears when they are in a dangerous situation on a mission.
To create a believable Rocket OC, consider their appearance. It should fit within the Guardians of the Galaxy universe. If they are from a cold planet, they might have some sort of fur or thick skin. Their personality also matters. They could be shy at first but open up as they get to know the Guardians. Their motivation is key. Maybe they want to prove themselves to Rocket because they admire him so much. And don't forget to give them a unique voice, both literally and figuratively. A distinct way of speaking and thinking will make them stand out and seem more real.
