Sigma is one of the characters in teen author Justin M. Anderson’s latest novel, Nothing But Trouble, and the unwilling mascot of Sigma’s Bookshelf.
Sigma is a teen with a lot of problems… the most prominent of which is having been turned into a lizard-like creature.
He is very sarcastic, and has a dry and dark sense of humor. He is hard to get along with, and is the kind of guy who would much rather eat someone than get to know them.
Below are several drawings of Sigma by Justin.
