White is a kingpin who loves white for no other reason than liking it. Some say he actually has a deep fear of the dark since he was born. Some say he fell into a washing machine when he was a kid. Some say the author is just lazy and didn't want to color it.

Anyway, White is 8 ft tall, weighs 2200 pounds (0% fat) and has an IQ of 250. He will fuck you up.
