Warg

A Warg (also called a Fenrir or Anfauglir) is a large Wolf-like creature. They usually appear early on in their games, often guarding the entrance to the Castle. In 2D games, their large forms block ones path and they occasionally growl or lunge with their jaws. Some Wargs are able to set the ground ablaze, including Fire Wargs and Warg Riders. Soma Cruz could use a Warg's soul as a weapon in Castlevania: Dawn of Sorrow, which caused a thirsty Warg head to appear in front of him, which performed a single biting attack.

Wargs in Castlevania can sometimes be mounted by other creatures, such as Skeletons, Lesser Lycanthropes or the demon Andras. Gabriel Belmont is also able to ride a warg in Castlevania: Lords of Shadow after he stuns it.

Fenrirs in Castlevania: Curse of Darkness tend to run around and claw at intruders. Wolf Skeletons, while first appearing in Castlevania: Lament of Innocence, are known to actually be undead Fenrirs in Curse of Darkness.

In Norse mythology, Fenrir was a great wolf and the son of the god Loki. Its sons were referred to as Wargs. Tolkien expanded this term to include a race of evil wolf-like creatures. Wargs that could not spew fire in Symphony of the Night are called Anfauglir (Jaws of Thirst) in Japan, which was a powerful wolf beast in Tolkein's Middle Earth.
