White Dragon

Any long-necked dragon skeletons. Sometimes called a Skeledragon, Bone Dragon, Quetzalcoatl, or Wyrm. There are two basic types of White Dragons, those with their necks bound to a wall, and those which are free to move around as they please (either float, bounce, or burrow). Any variety can be a boss in a game (often called a Bone Dragon King) and some of the names used can refer to any of the types depending on the games. Skeledragon is a term used in older American games used only for the bound variety. White Dragon can be used for a bound variety or a unbound variety. The term Quetzalcoatl can be used to describe a bouncing or free-floating unbound varieties. Some unbound dragons are controlled by fleaman riders called Dragon Riders. Some are considered the spines of deceased dragons, while others are said to be the remains of a long-necked dinosaur. Some still have their flesh in tact or are alive, but otherwise behave like their skeletal counterparts. The White Dragon boss in Castlevania: The Adventure ReBirth is normally bound, but is able to slither around the floors, walls, and ceilings.

Castlevania II: Simon's Quest
Unlike most bound white dragons, this one is bound to the ground instead of a wall.

Castlevania II: Belmont's Revenge
The Angel Mummy is essentially two bound White Dragons, the upper one having a human skull, while the bottom one has a dragon skull.

Castlevania 64 and Castlevania Legacy of Darkness
The White Dragons (The Dragon in Prima's Guide) is a two-headed dragon boss from the games Castlevania 64 and Castlevania: Legacy of Darkness.

They attack by releasing blue fireballs from the mouths. After one of the heads lose half of the energy, its color will change from white to gray and will release a large amount of fire from the mouth.

When one White Dragon loses half of it's HP it drops a massive amount of collectable materials, including Red Jewels, Sun Cards, Moon Cards, Gold (ranging from 100 to 500), Cross, Axe, and Holy Water. It then drops all those materials again upon defeat.

In Castlevania Legacy of Darkness it will only drop Red jewels, Sun Cards, Moon Cards, and Gold.

Castlevania: Curse of Darkness
Alternate elemental varieties of White Dragons in this game include Frost Dragon and Thunder Dragon.

Harmony of Dissonance
Found in only one room in the castle near the entrance to the final battle, the White Dragon Lv3 is unique in that it is not fastened to the wall, but instead roams freely around the background, flying and twisting around corridors, and not actively seeking out the player.

Aria of Sorrow
The Bone Dragon King appears in Aria of Sorrow, but is unnamed and is invincible. The dragon is summoned by Chaos, and protects the core of Chaos, flying around and shooting spheres of goo that ricochets off of the walls. The Bone Dragon King does not have an entry in the bestiary, and is only defeated when Chaos is defeated.

Belmont's Revenge
The Ground Serpent (called such in Japan and the Bone Dragon in North America) was one of the bosses that could be fought in Dracula's Castle in Castlevania II: Belmont's Revenge. Its long body burrowed in and out of the ground in a weaving pattern.

Harmony of Dissonance
Although the Bone Dragon King never appears in Harmony of Dissonance, a leveled-up White Dragon acts similarly to the Bone Dragon King, and Death's second form looks like and acts similarly to the Bone Dragon king as well.

Castlevania: The Adventure ReBirth
The Bone Dragon King in this game is normally bound to a wall. However, it can detach itself and crawl around before perching on another wall. It can also shoot blue energy blasts and smash its head against the floor.
