“Well your parents wanted you to get plastic surgery, no? Well they came to me to make you perfect and I did just zat.”
— Dr. Socks explaining to Leto that her parents wanted her to get plastic surgery.
Dr. Socks is an evil scientist who runs his own business of being a "plastic surgeon". (He calls it this to get human's attention.)
When humans don't ask him for plastic surgery, he practices on his potion making skills.
He regularly makes potions that transform him into a human so he can talk to them. His normal form is a heatling (for which he is a heatling).
When he gets mad, he turns red, he catches himself on fire and his german accent disappears.
