Stan has a conniving personality. He is greedy and a sadistic Exterminator. He smokes heavily and is rude to others while smoking and talking to other people as well. He also is very murderous being he tried to destroy the hive of ants Lucas had asked him to do.
Stan is a slob with no regard for his personal hygiene and is very dirty. So dirty that flies fly around his stinky body and clothes. He also has a scruffy face, greasy-looking dark brown hair, and brown eyes. He also dresses in a cruddy red Exterminator suit.
