Is there a specific name for the stereotypical personality type displayed by reluctant heroes in movies today?

Sorry if the question is a bit confusing but I'm referring to the reluctant heroes in movies like Disney movies and video games. Let's use Flynn Rider from Disney's "Tangled" as an example. He's not born a hero, he's a bit cocky and has boyish charm, he's not highly intelligent, he rushes into action, and he doesn't live such a honest life before his heroism. However, in the end he uses his stupid boyish charm, pulls a stunt or two, gets favored by luck and ends up winning the girl and saving the day. Is there a specific characterization or named character type that fits into this role?
