Wolf

A Wolf (Canis lupus) is the largest extant wild member of the Canidae family.

On Gaia, Wolves were introduced during the 2007 Halloween event. However, they would not be seen for three years afterward. They made a return during the 2011 Halloween event as the result of drug induced lycanthropy, Gaians changing into werewolves. A werewolf is a mythological or folkloric human with the ability to shapeshift into a wolf or an anthropomorphic wolf-like creature, either purposely, by being bitten by another werewolf, or after being placed under a curse.

Anatomy
Wolves are slender, powerfully built animals with large, deeply descending ribcages and sloping backs. Their abdomens are pulled in, and their necks heavily muscled. Their limbs are long and robust, with comparatively small paws. They have large heads and blunt muzzles, their ears are triangular. The common fur shades are, black, gray, and brown.

Other types
During the Halloween event, as Gaians were being turned, there were a variety of wolves to appear, one that stood out in particular was the "Sparkledog", a colorful wolf-like creature decorated in accessories. Others seemed to appear elemental, and reflect that by fur color, such as the Ice and Shadow. And bright colors such as blood red.

Connection
The wolves resemble the common gray wolf with its most obvious anatomical features, despite some wolves being more colorful than others.

Behavior
There has not been much history to judge the behavior of the wolf, however, based on the events, wolves seem to behave much like a real wolf would.

Halloween 2007
In this event, a manga and two short films were released to tell the tale of the vampires in Gaia. The Von Helson Sisters were back, and were revealed to be a part of a family of vampires. The short film MMVII:White Eclipse introduced a white wolf that made an attempt to attack Moira, it was later hunted down by Louie Von Helson and killed.

Halloween 2011
In this event, a manga was released that was about how Halloween events effected the citizens of of the towns. Louie and Ian wanted to throw a masquerade to defuse the peoples fears.
 * Halloween 2k11

The peaceful theme of the party lasted only for a moments as citizens that consumed a new product called Gro-Gain Max, were effected with a case of lycanthropy as a resulting side effect, the masquerade quickly became overrun with rampaging werewolves; nearby clans of werewolf hunters swarmed in to the fight.

Trivia

 * Due to drug induced lycanthropy, it is currently unknown if werewolves of Gaia are effected by lunar changes.
