Dursleys took good care of him. So he is physically strong. Harry Potter is sorted in Slytherin. First two years, he tried to become friends with everyone but Slytherins didn't like the idea and other houses hated him especially Ron because he was Slytherin. All events happen the same way, but he does it alone, he is the smartest kid in his year. He is also the topper of the year. He would stop Slytherins from bullying others so that he can become friends with other houses due to which he used to get a beating from his housemates in Dungeons by all the Slytherins. In 3rd year, he made a deal with Draco that he will not stop them from bullying and become their friends if they don't bully in front of him. Draco agreed. Slytherins have won all quidditch cups with honesty as Harry being their seeker and House cups because of Harry's smartness. The story starts in Harry's 5th year on the train. I don't own Harry Potter. It's owned by JK Rowling.
