Water Dragons are giant sea dwelling dragon-like beasts. The first such creatures appeared as an incarnation of the Greek mythological beast Hydra, which had several heads.
They were called Water Dragons in Dracula's Curse, and Orphic Vipers in Super Castlevania IV. The latter wave all around and attack in their own ways: one breathes a short-ranged flame, and the other spits three-directional fireballs. Although referred to as two different monsters in the western localization of Super Castlevania IV (probably referencing the dragons from Dracula's Curse), in the Japanese version it is called Twin Head Dragon, making it a single creature with two heads.
A single headed serpent appeared in Rondo of Blood as the harder alternative to the first boss of the game. A version of this creature with arms appeared as the first boss of Legacy of Darkness. This Water Dragon also made an appearance in Castlevania: The Arcade.
An icy water dragon called Rahab first appeared in Boku Dracula-kun. It was later mentioned in Symphony of the Night, where the Icebrand sword was referred to as Rahab's Sword in Japan. In Portrait of Ruin it's also referred as Rahab's Sword, and it would be called the same in Aria of Sorrow. The great beast made its second boss appearance as a more fish-like creature in Dawn of Sorrow. Certain attacks would cause a brittle ice bridge over the surface from which one could walk on.
