Ernst Stavro Blofeld (born as Franz Oberhauser on October 4th, 1956) is 5'7 tall, has short-cropped greying hair, grey-green eyes, a square chin, and a slim build. Usually, he is wearing dark, simple clothing. 

Ernst is highly intelligent, manipulative, charming, arrogant and incredibly influential. There's something of a jealous, narcissistic control freak about him. He can be very sadistic and has low empathy, as well as no feelings of guilt or remorse.
