Sea Dragon is a type of monster in the Monster Hunter series of games. It is a sea dragon monster and also the earliest discovered sea dragon monster. In the game, it is known as the "Sea Dragon" or "Deep Sea Overlord" and is referred to as the "Lord of the Sea". Its organs on its back store lightning power, filling the nearby ocean with high voltage electricity. The back of the sea dragon's body is covered with a blue-green shell, and its belly is covered with delicate milky white skin armor. It has five pairs of brown discharge organs on its back, two of which are longer and the rest are shorter. When using powerful lightning strikes, its back skin emits white light, and when it is angry, its mouth sprays lightning.
