Yao guai (Honest Hearts)

Yao guai are a species of mutated black bear found in Zion Canyon in 2281.

Biology
The yao guai of Zion Canyon are visually identical to the yao guai of the Capital Wasteland, but are typically larger. In Zion Canyon, they form small dens of three to four yao guai and live in the multiple caves the pocket the canyon. They exhibit a gentle, familial bond toward those in their dens, provided they do not feel threatened by an observer's presence. Yao guai will attack nearly any other animals or people they encounter. They apparently subsist only on the geckos that inhabit Zion, as they do not attack bighorners in the same area. This may appear uncharacteristic, but is consistent with predators not unnecessarily exhausting their food supply.

Gameplay attributes
Yao guai are extremely fast and powerful creatures, second only to deathclaws in terms of raw strength and speed. Unlike deathclaws, they are less alert; the player may come in contact with one when it is asleep or laying down. Unlike in Fallout 3, yao guai are not affected by the Animal Friend perk and will attack on sight. The Sorrows tribe has been able to use yao guai paws to create yao guai gauntlets. These gauntlets use the weight of the bear's paw and its sharp claws to deliver a vicious attack.

Yao guai
These creatures are nearly identical to the yao guai found in the Capital Wasteland. They are second to only the deathclaw in terms of raw strength and speed. They are also normally found in groups of two to four.

Yao guai cub
Yao guai cubs are simply smaller, weaker and less deadly versions of their parents. They are encountered with their parents. At lower levels they may replace encounters with older varieties.

Giant yao guai
Giant yao guai are larger versions of yao guai. A giant yao guai can easily kill a low-level player if they're not careful. Early in the Honest Hearts add-on, a giant yao guai attacks and kills a green gecko on top of a rock while the player approaches the Dead Horses Camp. A few of these can be found near The Red Gate.

Appearances
Yao guai appear in the Fallout: New Vegas add-on Honest Hearts.
