Which McDonaldland character debuted in 1971 as a striped thief who wanted hamburgers?

The Hamburglar debuted in 1971 as a striped thief who wanted to steal hamburgers.

He was one of the main characters in McDonald's McDonaldland advertising, a fictional setting built around Ronald McDonald and other personified brand figures. The early Hamburglar had a more sinister appearance, but McDonald's later redesigned him as a smaller, younger, and more playful character for a child-focused audience.

His black-and-white striped clothing, cape, gloves, and repeated hamburger obsession made him visually easy to recognize. The Hamburglar is sometimes confused with Captain Crook, another McDonaldland villain associated with Filet-O-Fish. Their separate roles show how McDonald's used characters to give individual menu items their own advertising identities.
