If you're a Zombies fan, specifically a Black Ops Zombies fan, chances are that you've heard of the Ronald Raygun, the name of which is clearly a play on former US president Ronald Reagan, who served from 1981 to 1989.
Ronald Reagan also appears in the Black Ops Cold War campaign as the United States president. It makes sense, as he was the president during the real-life Cold War era. After all, Call of Duty games are known for non-fictitious characters and being heavily inspired by real war events.
There is a brand new easter egg added in the Outbreak mode which not only guarantees a Raygun, but is also very rare to come across. Treyarch has added a unique zombie with a pink-haired mohawk in the game named Ronald Raygun.
Ronald Raygun has been a meme for quite some time in the Zombies community with the last name "Reagan" sounding very similar to "Raygun", hence the play on the words resulting in Ronald Raygun.
