Wolf

Gray wolf (Latin: Canis lupus) also known as the timber wolf, or western wolf, is a canid native to the wilderness and remote areas of North America, Eurasia, and northern, eastern and western Africa.

Background
Gray wolves originated in Eurasia during the Pleistocene, colonizing North America on at least three separate occasions during the Rancholabrean. Unlike dogs, which were domesticated from them, wolves are difficult if not impossible to tame and had a checkered reputation among humans, blamed for attacks on livestock and humans alike. Despite that, wolves were also widely respected and became a synonym for strength, loyalty, and teamwork. The nuclear holocaust had a limited impact on the common gray wolf, primarily in the form of freeing up land previously occupied for humans by their use. The wolves steadily proliferated, carving out a niche in between other apex predators vying for the same resources and soon became a common sight in various wasteland areas, including New California. Although the nuclear fallout had a marginal effect on most wolf populations, isolated groups like the ones inhabiting the wilds of Mount Desert Island, have steadily succumbed to the twisting influence of radiation and other environmental factors.

Wolf
There is little variation among the wolves of the wastes, unlike dogs descended from them. They are large, fast, and vicious if threatened. They tend to travel in packs and will defend one another to the death.

Appearances
Wolves appear in Fallout, Fallout 2, Far Harbor, and Fallout Tactics: Brotherhood of Steel. They are mentioned in Fallout 3, and were to appear in Van Buren, the canceled Fallout 3 by Interplay Entertainment''.
