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.

Mercer's shape - shifting abilities could be an interesting contrast to the mutants' powers, and there could be a conflict or an alliance depending on the story's direction.
