Which McDonald's character was designed as a living version of the Big Mac sandwich?

Officer Big Mac was designed as a living version of the Big Mac sandwich.

The character appeared in McDonaldland advertising as a police officer with a head shaped like a Big Mac. His design turned a menu item into a person within the fictional advertising world, allowing McDonald's to promote product identity through character-based storytelling.

Officer Big Mac belonged to a broader group of branded figures that included Ronald McDonald, Grimace, the Hamburglar, Mayor McCheese, and Birdie. Each character used exaggerated visual cues so audiences could identify a product, personality, or role quickly. Officer Big Mac's most obvious cue was the sandwich itself.

He is often confused with Mayor McCheese because both characters have food-based heads and civic titles. Mayor McCheese's head was a cheeseburger, while Officer Big Mac's design specifically referenced the Big Mac. This distinction makes the character a precise example of product-based branding.
