Which McDonald's mascot was created as a thief who tried to steal hamburgers?

The Hamburglar was created as a McDonald's mascot who tried to steal hamburgers.

The character became part of the McDonaldland cast and was portrayed as a small, mischievous figure obsessed with hamburgers. His striped clothing, cape, and exaggerated speech made him visually distinctive in television commercials and promotional material.

The Hamburglar's design changed over the years. The earliest version looked more like an older villain, while a later redesign presented him as a younger, cartoon-like character. Despite those changes, the central joke remained his desire to take hamburgers from McDonald's.

The Hamburglar is sometimes confused with Captain Crook, another McDonaldland character. Captain Crook was associated with Filet-O-Fish sandwiches, whereas the Hamburglar's defining target was hamburgers.
