Well I caught it. Here's what I got:
Scar (The Lion King)
Kovu (The Lion King 2)
Zuko (Avatar: The Last Airbender)
Luke (Percy Jackson)
Tyrion (Game of Thrones)
Drago Bludvist (How To Train Your Dragon 2)
I want to know why the trend has been appearing so much. xD
At least Harry Potter has the scar on his forehead and is the main character.
