Originally named by the descendants of those held in Chinese internment camps before the Great War, the Yao Guai is a ferocious mutated bear.Fallout 4 loading screen hint

Yao guai are a species of mutated bears that inhabit the Commonwealth, the Island and Nuka-World in 2287.

Background[edit | edit source]

Named by descendants of those held in Chinese internment camps before the Great War, yao guai are mutated American black bears[1][2][3] and one of the more vicious creatures of the wasteland, sporting razor sharp claws and teeth, and a nasty temperament.[4]

Characteristics[edit | edit source]

Yao guai are large, mutated ursines that are descended from the bears that lived across America before the Great War. They are able to reproduce, as evidenced by the presence of cubs and some have extended lifespans, such as the pre-War circus bear, Ruzka. Wild yao guai will attack nearly any other animals or people they encounter, including deathclaws. Despite this, yao guai exhibit a gentle, familial bond toward one another when found together and can even be domesticated.[5]

Gameplay attributes[edit | edit source]

They seem to appear as often during the daytime as they do during the night. This is a primary difference between the Commonwealth yao guai compared to the Capital Wasteland variants which are more nocturnal in nature.

These creatures also have the ability to cause, unlike their Capital Wasteland counterparts, the staggering effect on every one of their attacks, even if the player character is quick enough to block them. For this reason, melee fighting against yao guai might be difficult, especially with slow weapons or if fighting against a group. Attacks must be properly timed, otherwise, the player character might get stuck in the stagger effect, giving yao guai enough time to strike once again.

Variants[edit | edit source]

Stunted yao guai[edit | edit source]

Fo4 stunted yao guai.jpg

Not as physically imposing as normal yao guai due to minor malformations, past injuries, or arrested development. As a result, they are less of a threat compared to other variants. Wherever they are found with another yao guai it is usually one with a similar affliction.
