Lantern goblins are people who have been possessed by evil spirits that are under the control of jack of the lantern. These spirits can only posses you on Halloween and can only be warded off by a lit jack-o-lantern. Once you've been possessed, you are a under Jack's control. With heightened abilities, like super strength and speed, you make a pretty good evil minion. Oh, and did I forget to mention that you also have a horrible little hankering for flesh?
