|This needs a stretch.|
Jack O'Lantern is a living pumpkin monster.
Insert details here.
It has a fun-loving mind of its own unless it was joined to the Headless Horseman, which could make Jack act as his head.
Powers and abilities
He can breathe a stream of fire, only once as this burns out his candle(his lifeline).
