Everyone has a skill or something special about them that they are known for. Harry Potter, for example, the main character in Harry Potter and the Sorcerer's Stone was written by J.K. Rowling, is known for being "the boy who lived". His skills are defeating He-Who-Must-Not-Be-Named a.k.A Lord Voldemort. Although also very important, his personality and Quidditch skills tend to stand out last. Harry is a wonder in himself. He is an eleven-year-old scrawny kid who single-handedly defeated one of the most powerful wizards of all time, and he didn't even have a wand to defend himself. This is the first thing that automatically gets him noticed. Ever since that day when he was a toddler, he has been the most famous wizards. Kids grew up hearing about him from friends and family; older witches and wizards celebrated in his name, various books even had his name printed on them. Every witch and wizard who doesn't live under a rock know about him and what he's done. It is a great thing to be known for something great, but it tends to be the only thing others define him as. To most, he is only "the boy who lived.".
Another thing Harry is known for is his Quidditch skills. In his first year, thanks to Draco Malfoy, he becomes the new Gryffindor Seeker and the youngest house player in a century. His skills are thought to be inherited by his father James Potter, who was also a Quidditch player. This unknowingly gathers more fans for Harry, and further increases his popularity. Harry Potter is more than "the boy who lived". His personality is a major thing that his friends notice after the fame and fortune. He is brave, humble, loyal, modest, and kind. However, most people don't see that until after they see the fame and glory behind his name. When he becomes an outcast, most don't stick around to see what's behind the famous face. His friends and some of his teachers notice, but that's it.
