Nightkin

The Nightkin are an elite warrior caste in the Master's super mutant army and the apex of his creation.

Overview
They are superior to their fellow Super Mutants both in intellect and skill, as the FEV-II dipping has not damaged their intelligence. While in the Master's Army, they have access to superior weapons and armour, including the stealth boys.

Prolonged use of the devices led to a permanent alteration of the pigment of their bodies - instead of the usual dull-green, their skin is sky-blue.

Fallout
They can be found in the upper levels of the Cathedral, as well as inside the Mariposa Military Base, including the nearby cells surrounding it in the form of random patrol encounters. After the Master's fall, many surviving unity super mutants had become a chaotic wasteland wandering force, set on to destroy everything it encountered.

They are superior to other super mutants in skill, equipment, and weaponry. Many of the nightkin are equipped with cloaking devices, such as stealth boys. The only gaming effect of this is to give them a slight ethereal look, as it does not affect the PC's chance of hitting them.

Fallout 2
Some of the roving super mutant bands include nightkin. However, they no longer use stealth boys.

Fallout: Brotherhood of Steel
Also, other parts of super mutant army, after the death of Master, are gathered and formed a new faction, led by Attis.

Many years after their regrouping, these mutants captured the Secret Vault in order to use the FEV reserves stored in it. Attis's goal was to continue the Master's plan. His army had an elite unit of nightkin, much improved in skill, and equipped with high-tec suits to enhance their abilities and has the same function as the stealth boy. These suits probably originated from, or were made in, the Secret Vault.

Fallout: New Vegas
Some of the Nightkin reappear, suffering from severe psychological disturbances (schizophrenia and psychosis are most common), which are a side effect of prolonged Stealth Boy use.

A Nightkin is responsible for the nightly slaughter of Dusty McBride's Brahmin in Novac every night around midnight. He can be found during the day cloaked behind a boulder to the west of the city just across the road. Here, you can hear him complaining about constant insomnia and trying to shush voices that only he can seem to hear...

The follower, Lily, is a nightkin and a former soldier in the Master's army.

Some Nightkin are Antlerists, and believe in their God, Antler and take orders from him/her.

Nightkin play an important part in the quest Come Fly With Me. They are holding the basement area of REPCONN Test Area.

The Nightkin in "Fallout: New Vegas" can be found wielding a weapon known as the Rebar Club. They are believed to be a more intelligent version of 3rd generation super mutants (listening to the black mountain radio).

Bugs

 * In Fallout: New Vegas, the shaders that make Nightkin invisible will sometimes be bugged, causing them to remain invisible after deactivating their Stealth Boys (although they will be treated as visible for the purpose of calculating VATS percentages). This has been observed in the REPCONN Test Site basement, and appears to be linked to reloading a save in the basement after being killed.

Appearances
The nightkin appear in Fallout in the Cathedral and the Mariposa Military Base, in Fallout 2 as a hostile encounter on the world map, in the Secret Vault in Fallout: Brotherhood of Steel, and make a comeback in Fallout: New Vegas.

Behind the scenes
In Fallout 3, the word 'Nightkin' occasionally appears in the password list when hacking a terminal.
