The Harlequin monster is modeled and named after a classical form of clown known as a harlequin. Harlequins were distinguished by dressing in clothing covered in diamond color schemes of orange/red and green/black which the feathers of the Harlequin Demon channel. They are also portrayed as having jester hats which the three tentacles of the Harlequin Demon resemble. In classical tradition, Harlequins were trickster characters who often played demons or the devil in story performances, hence the nature of the Harlequin Demon.
