Gulper

Gulpers are mutated creatures found in Appalachia and on the Island.

Biology
Salamanders altered by both the nuclear fallout of the Great War as well as the persistent radiation of the Fog. These creatures have grown exponentially, towering over most humans.

One of the rare creatures found on the islands of Maine, they share their special attacks and animation set with the deathclaws. Gulpers roam the Island, at times hanging on trees in order to take their victims by surprise. They can also slide through swamps and hide underwater, where they are commonly found.

In Appalachia, gulpers can be found throughout the Mire and the Cranberry Bog. They stand with a hunched back, upright on their hind legs when moving slowly or standing still. They run using all four legs and are able to outrun a non-mutated human. If a player gets too close, they can pounce and swing their claws, dealing damage. When engaged in combat, they will rush towards the player, trying to dodge bullets if shot at, and will strike with various melee attacks.

Gulpers have the passive ability of slowly regenerating health and they will not enter buildings or climb stairs. If a player enters a building or uses stairs, the gulper will retreat but stay in the general area.

Appearances
Gulpers appear in the Fallout 4 add-on Far Harbor and Fallout 76. The young gulper appears only in Far Harbor. The Scorched gulper was introduced in Fallout 76.

Behind the scenes
Gulpers resemble the geckos found in Fallout 2 and Fallout: New Vegas.
