Top 9 World’s Most Famous Ghosts (3 of 5)
Casper the Friendly Ghost
Just as Slimer isn’t concerned about rattling any phantom chains, this little guy also doesn’t want to scare people. Created in the 1930s by Seymour Reit and Joe Oriolo, Casper became a comic book and cartoon star, alongside friends like Wendy the Good Little Witch. His wholesome persona made death oddly kid-friendly, though some people have debated whether jokes about the afterlife go hand-in-hand or should be banned.

King Hamlet
From one written story to the next one, we have Shakespeare, who loved a good ghost plot. But none of them comes even close to King Hamlet in Hamlet. Without his midnight appearances, there’d be no revenge plot, no brooding prince, no “To be or not to be.” The apparition that escaped the Purgatory claims he was killed by his brother Claudius and demands justice or, as he puts it, “vengeance from beyond the grave.” Spooky!
