Reinhard Moonstag is a German rapper. In the early 1990s, he starred in McDonalds commercials as a German knockoff of Mac Tonight, the McDonalds mascot played by Moon Man. While his position as a competitor of Moon Man has placed him and Moon Man at odds from time to time, Moonstag is generally supportive of Moon Man in his genocidal quest to kill all non-Aryans.

He has appeared on several songs, such as some on The Killing Moon. He has also personally introduced Moon Man to the stage in Bavaria for his performance which was part of the infamous Lunatic Tour.
