The "Guivre" or "wivre" is a serpent-like dragon of the European folklore, that used to dwell on rivers and lakes. It could attack by shooting water from its mouth, or with a highly poisonous breath.
During the Middle Ages, guivres were accused of spreading plagues and diseases.
According to a French legend, a method to defeat this monster was casually discovered. A young boy was bathing on a river when the dragon appeared and, when the boy came out of the water naked, the huge serpent felt ashamed and abandoned the place immediately. Since then, that was the method used to scare off these beasts.
This card may have inspired Jurak Guivre; each has a similar effect of special summoning a card when it destroys a monster.
