A popular aspect in this type of fanfiction is the relationship development. At first, there may be mistrust between Alex Mercer and the OC. Maybe the OC has heard rumors about Mercer being a threat. But as they are forced to interact more, they start to see each other's true selves. The OC might see the good in Mercer that others overlook. This can lead to a romantic relationship in some fanfictions, but not always. Sometimes it's a deep platonic bond. For instance, they could be like comrades - in - arms, relying on each other's strengths to face the various challenges in the Prototype world.
First, you need to understand the character of Alex Mercer well. Know his backstory, his powers, and his motives. This will help you create a more believable interaction with your OC. For the OC, give them a distinct personality and backstory too. They should not be a flat character. Second, start with an interesting hook. It could be a situation where the OC and Mercer first meet in a dangerous or unexpected way. Third, develop their relationship gradually. Don't rush into a deep connection right away. Let it build over time as they face challenges together.
