Which McDonald's advertising character was designed as a hamburger-headed mayor?

Mayor McCheese was designed as a hamburger-headed mayor in McDonald's advertising.

Mayor McCheese appeared in the McDonaldland advertising universe as a civic leader whose head resembled a cheeseburger. His design combined an oversized hamburger, a mayoral sash, and other exaggerated visual cues to make the character immediately legible to children.

The character belonged to the same imaginative advertising world as Ronald McDonald, Grimace, the Hamburglar, and other branded figures. Each character had a distinct role, which helped McDonald's turn menu items and restaurant themes into a recurring story setting.

Mayor McCheese is sometimes confused with Officer Big Mac because both were humanlike characters connected to McDonaldland's civic structure. Mayor McCheese's defining feature, however, is the hamburger head and mayoral identity.
