It could start with a simple act of kindness, like Chopper treating the OC's injury. Then there's the 'shared secret' trope. They might share a secret that only they know, which deepens their connection. And the 'power - up' trope, where the OC somehow helps Chopper unlock a new level of his power, or vice versa, through their strong emotional bond.
One common trope is the 'fish out of water' situation. The OC, being new to Chopper's world, might struggle to adapt to the strange and often dangerous pirate life. For example, they could be shocked by the battles and the rough nature of the crew at first. Another trope is the 'healing relationship'. Chopper, being a doctor, could heal the OC not just physically but also emotionally, and in turn, the OC could help Chopper grow in confidence and understanding of human relationships. There's also the 'adventure buddies' trope where they go on various adventures together, facing challenges side by side and relying on each other's unique skills.
