He is best known for his dynamic illustrations of giant robots — bringing iconic characters to life through comic covers, toy packaging, and concept art for companies like Hasbro, Marvel, IDW Publishing, Wizards of the Coast, and Skybound/Image.

Marcelo’s work appears on the Transformers Studio Series 86 toy line, G.I. Joe Classified Series, Marvel Legends packaging, and hundreds of officially licensed comic book covers.

In 2024, he made history as the first Brazilian artist inducted into the Transformers Hall of Fame.

“Marcelo’s artwork is the heartbeat of modern Transformers — no one draws bots with more energy and emotion.”
