No, not Harry Potter's scar.

The Scar™ is a reference to the distinctive slash mark across Katherine Johnson's neck. This scar was given to her via sword in the 85th Annual Hunger Games by the famed (and then 17-year-old) Leah Matrix after Katherine's attempt at an attack. After the slice that would later become The Scar™ was dealt, Katherine left as the first tribute in recorded history to survive an attack by Leah Matrix.
