Marcelo Cassaro

Marcelo Cassaro (born August 15, 1970) is a Brazilian writer of comic books, role-playing games and the science-fiction book "Sword of the Galaxy" ("Espada da Galáxia"). 
Early career.
In 1985 at age fifteen, Cassaro became a design assistant and in-between artist for animated cartoons in the Maurício de Sousa studios. In 1989 he was hired as an artist and screenwriter by Abril Jovem for television shows like "Joe Carioca", "Os Trapalhões", and "Jaspion".
Award winning writer and artist.
In 1999 Cassaro created with artist Erica Awano the manga book "Holy Avenger"; it became the longest published non-child-oriented comic in Brazil. Like Japanese manga, the first three pages of each chapter were printed in color, while the remaining pages were black and white, and each issue had a two-page map showing the journey of the characters, a summary of previous events, and profiles of the main characters. But going against the standard practice of printing manga so that it read right-to-left, which conformed with Japanese reading practices, "Holy Avenger" was printed to be read left-to-right instead. It was the first Brazilian manga book to sell 30,000 copies each month. Forty issues were published from 1995 to 2004.
Cassara also worked as author and editor on: 
In 1995, Cassaro started "Dragão Brasil", the first Brazilian monthly magazine specialized in RPG games, and the only one to complete more than 100 editions. He left that position and worked as an author of RPGs based on licensed video games such as "Street Fighter", "Final Fight", "Darkstalkers" and "Megaman". He is also one of the authors of "Tormenta", the most successful RPG in Brazil; and "3D&T", an RPG game based on manga and anime.
In 2009, Cassaro started writing for "Turma da Mônica Jovem", the best selling comic book in South America.
