Tunnel Snakes

The "" is a gang of greasers in Vault 101. They wear Grease-style brown leather jackets over their vault suits and have recognizable 1950s haircuts. The members of the gang are Butch DeLoria, Wally Mack, and Paul Hannon Jr.. The leadership of the gang shifts consistently between Butch and Wally, with Paul following whomever is in charge at the moment. One other Vault resident, Freddie Gomez, desires membership in the "Tunnel Snakes" gang and the gang members approve of Freddie's bullying of his peers. Freddie's father, Officer Gomez, disapproves of his son's association with the gang.

In the late 2260's, the young Butch is actively organizing the gang and recruiting new members. During a late afternoon meeting on July 13, 2268, Butch holds an open panel for possible gang names. Wally suggests "Mackers" and "Hell's Overseers"; whereas, Paul suggests "Grease Weasels", "Vaultikins", and "Vault Dwellers". Butch suggests "Vault Rats" and "Vault Snakes". The name "Vault Snakes" was eventually accepted by the gang, and changed to "Tunnel Snakes". A carefully drawn and designed snake is sewn onto the leather surface of the jackets' backs. The snake's body forms the letter 'S'.

Many years later, on August 3, 2274, the gang members are harassing Amata Almodovar near the classroom. They are chiding her for being a daddy's girl and a daughter of the Overseer, and the gang would give her a good time in the storeroom. By a good time, the young males are implying sexual intercourse. Amata is offended and frustrated by the unwanted sexual advances of the gang members, and visibly protects herself by crossing her arms across her chest. In this situation, a player's character could chose one of three possible paths. The paths could involve a player's character helping Amata for good karma, helping the "Tunnel Snakes" for bad karma, or forcing Amata into resolving the situation for herself.

It is later discovered by the Lone Wanderer while accessing the Overseer's computer that the Overseer has used them to harass people in secret in situations where having his security force do so would be undesirable. ("Escape!")

Appearances
The Tunnel Snakes appeared only in Fallout 3. Male player characters could choose to have the same haircut as Butch. The haircut is named "The Tunnel Snake".

Trivia
When Butch DeLoria, Wally Mack and Paul Hannon Jr. discuss about the gang´s name during the Lone Wanderer´s birthday party, one of the names purposed is "Vault Dwellers", what may be a reference to the main character of Fallout 1. Also, Butch negatively responses to the name, claiming it to be riddiculous.
