Tunnel Snakes

The Tunnel Snakes are a gang in Vault 101, composed of greasers from Vault 101. They wear Grease-style brown leather jackets over their vault suits and have recognisable 1950s haircuts. The members include Butch DeLoria, Wally Mack and Paul Hannon Jr.

Shortly before taking the G.O.A.T. exam, they can be found harassing Amata outside of the classroom, and the Vault 101 Dweller can either help her or take their side.

The leadership of the gang is nebulous. While Butch often acts, and is formally the leader, whenever Wally insists that he's in fact the leader, Butch will not argue against him.

It is later discovered by the Vault 101 Dweller 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.

Appearances
The Tunnel Snakes appear only in Fallout 3. Male player characters can choose to have the same haircut Butch sports, also named "The Tunnel Snake".
