Harry was Sorted into a Different House

Not the most original idea but still a fun one. Everyone just assumed Mr. Potty would be sorted into Gryffindor like his parents but what if he wasn't. Since the Sorting Hat will always let the person decide where they want to go. So what if Harry Potter ask to be sorted into another house but why ?

Maybe Harry meet someone in Diagon Alley that showed him that Slytherin wasn't just bullies and jerk.

Maybe Harry meet someone on the train that showed him the House of the Ravens can quench his thirst for knowledge.

Maybe Harry stood up for someone to show his loyalty, showing him his true color was yellow.
