Jack Oh' Lantern also known as Stingy Jack was a drunkard in Ireland who died of drinking too much alcohol and was forced to roam between the planes of good and evil for his sinful ways.
Every Halloween, Jack Oh' Lantern tries to come to the mortal realm and take revenge on it. Every time though someone like Mike, Bern, Hatter, or Steve stop him with hilarious results.
