Uncanny Valley (Morph Trait)

There is a point where synthetic human looks become uncannily realistic and human-seeming, but they remain just different enough that their looks seem creepy or even repulsive phenomenon called the 'uncanny valley'. Morphs whose looks fall into this range suffer a -10 modifier on social skill tests when dealing with humans. This modifier does not apply to interactions with xenomorphs or those with the infolife or uplift backgrounds.
