Name-Face Name

Nicknames can say something about a guy. A deformity, mask, or the looks of a person can give them a Name-Face Name. A Name-Face Name is when a character's nickname comes from a characteristic of their face.

Often leads to Only Known by Their Nickname.

Compare Captain Color Beard.

Examples of Name-Face Name include:
