Ivan Reis was born in São Paulo, Brazil. He started his career at the age of 14, working with Brazil’s famous cartoon artist, Mauricio de Sousa. Through this association, he contributed to the review Histórias Reais de Drácula, published by Bloch Editores, and drew several cartoons for Editora Fênix. At the same time, Reis worked for an advertising agency. Then in 1995, he attracted the attention of Dark Horse Publishing in the United States and appeared in their anthology, Dark Horse Presents. Ivan became the penciller on a title called Ghost, and continued to work on that project until 1996. Other Dark Horse books that Reis illustrated were Time Cop, The Mask, Máscara and Xena. During this period, he also drew a number of Lady Death comics for Chaos! In 1997, another American comic book company took notice of Ivan. That company was DC Comics.
