Here's a Trait.
Only a Mother Could Love* - Character has a terribly disfiguring feature on their face. Depending on EXP invested, such a feature can either Intimidate, or mentally scar (Fear?) people. Depending on situation, can either add a +4 or -4 to Negotiation Rolls, and, during the beginning of a combat phase, the enemy must make a Concentration Roll to not be distracted by said feature.
Sounds more like a Flaw.
