The Quartet of Villains is a group of four unnamed villains who appears in the Ninjago: Masters of Spinjitzu graphic novel Stone Cold. Each appeared to be either an inhuman creature or else a human wearing a costume, with its members resembling a vampire, a humanoid moth, and two lizard-like humanoids. They were previously imprisoned in the Tower of Tears by Sensei Wu before being released by Lord Garmadon, only to be defeated as Sensei Wu started going after his old foes rather than waiting for them to attack him.
