Cyclops

Characteristics
From the basis of a human, cyclopi have a single eye each in the center of their foreheads, in place of two eyes. The size of their eyes vary among them.

apparently, the size of the eye indicates how much magical power they have, so cyclops with small eyes tend to have low self-esteem.

Also, it seems that females who have smaller eyes have bigger breasts and vice versa.
