The Kraken is a fictional sea monster. It is based on the mythical beast in mythology (extremely redundant). It is a sea monster that does the bidding of Davy Jones. When summoned by him, it arises from the ocean. Often Davy Jones tells it to destroy ships that he believes threaten or annoy him. The Kraken kills Jack Sparrow and destroys the "Black Pearl" but Jack lived. The Kraken is Killed in fact by Davy Jones. He has a lizardy kind of skin.
