To create a compelling OC mercenary, start with their motivation. What drives them to be a mercenary? Is it money, revenge, or something else? Then, think about their appearance. A cool - looking weapon or a unique style of dress can make them stand out. Also, consider their relationships. Do they have an old friend or a mentor from their mercenary days? These relationships can add depth to the character. They should also have flaws. Maybe they're too impulsive or too trusting at times. This makes them more human and interesting.
