The Judge, played by Brian Thompson, is a character in the television series Buffy the Vampire Slayer.
Judge is an ancient and legendary blue-skinned demon from the Middle Ages. He was brought forth to rid Earth of the plague of humanity. He was named The Judge for he had come to separate the righteous from the wicked and burn the righteous down. In the 14th century an army was sent against the Judge, and though most of the warriors died, the army was able to dismember the Judge, but not to kill him, as "no weapon forged" can kill him. The pieces were placed in iron boxes and buried "in every corner of the Earth". For six hundred years he remained aware of his status.
In the two-part episode "Surprise"/"Innocence", he is restored by Drusilla after she has gathered together all the boxes, but is then blasted into pieces by Buffy Summers with a US Army FGM-148 Javelin rocket launcher, revealing that the "no weapon forged" rule from the 14th century was merely descriptive, not prophetic. The Scooby Gang picks up the pieces and keeps them separate.
