Harry Potter's Scar

Harry's scar is seemingly so small and insignificant but sums his entire existence. It doesn't do much to further the plot. The scar's whole purpose is to be one giant, everlasting symbol. It shows his intense past and his promising future, his acceptance of the world and his troubles with it. The Harry Potter Series is, at its core as most books are, the fight between good and evil. At the base of that fight is Harry, at the opposing side, Voldemort. The scar is the symbol of the relationship between them, thus the symbol of the whole book together. The scar is everything in the Harry Potter series. It's in the center of the plot, and the main character.
