Dog MendonçaJoão Vicente "Dog" Mendonça is a boisterous fat, football-loving, womanizer, kinda dumb AND portuguese Occult Detective who protects monsters from humans or otherwise who had broken the code (the code is the fact that monsters don't reveal themselves to the humans). He's always accompanied by Pazuul his assistant, it seemed the two had already dangerous adventures before (such as beating Loch Ness). Pizzaboy meets him to help him find his bike stolen from a bunch of Gargoyles. Eventually this is the beginning of a beautiful friendship.
PizzaboyHis name is Eurico Catatau but everyone calls him Pizzaboy (wich is kinda weird cause you know, the book is portuguese and you don't find many portuguese people saying "pizzaboy"). He works in a, well... pizza store, and dreams of getting the girl of his dreams and have a better job. So it happens his bike is stolen by a bunch of gargoyles. By taking the advice from a friend, Pizzaboy contacts Dog and Pazuul, eventually setting the beginning of a beautiful freindship.
PazuulA demon trapped in a little girl's body. Apparently he used to work for hell but was banished (the exacly reasons why are unknown but it seemed he wasn't evil enough), as of now he works with Dog as his assistant.
