The scar on Harry Potter's forehead represents his parent’s sacrifice in order to protect him. Due to her mother dying for her son, she gave Harry the most powerful protection she could: love. During an ancient ritual in which she stood in Voldemort’s way, Harry's mother dictated that should Voldemort ever try to attempt to curse Harry, each curse would come back at him. Specifically, Lord Voldemort's soul latches onto Harry Potter, which creates the scar. The lightning shaped scar is a significant symbol that separates Harry from all other magicians, such as a mark of destiny for a brighter future and a symbol of hope to all.
