Scar

Mad-Eye's many scars

The scar on Harry Potter's forehead was shaped like a Lightning bolt.

A scar is a permanent mark on the skin sometimes caused by a healed wound. Harry Potter has received many scars in his life, the most well-known being the lightning scar that can be seen on his forehead from where Voldemort's Killing Curse struck him as an infant. He, Alastor "Mad-Eye" Moody, Bill Weasley, and Remus Lupin are some notable wizards who have been scarred.
