Wally Mack

Wally Mack is a resident of Vault 101 in 2277, and is a member of a greaser gang called the Tunnel Snakes.

Background
Born in 2258, Wally is the brains of the Tunnel Snakes. He doesn't talk as much as the others, but they listen to what he has to say when he does say something. He is one of the Lone Wanderer's peers in Vault 101 and is encountered throughout the Lone Wanderer's youth inside Vault 101.

By 2287, Mack had traveled to the Commonwealth where he reestablished the Tunnel Snakes. Setting up their base of operations in Fens Way station, they discovered old radioactive waste barrels, with Mack believing that the gang could gain superpowers from them. Over time, Mack and the other Tunnel Snakes succumbed to radiation sickness, transforming into feral ghouls.

Relationships
During their formative years, the Tunnel Snakes harassed other students in Vault 101, even being bold enough to taunt the Overseer's daughter, Amata Almodovar. Butch DeLoria presumes to be the leader of the Tunnel Snakes, but Wally Mack might disagree if challenged.

Wally is the son of Allen and Gloria Mack. Wally's siblings are Stevie and Susie. Butch DeLoria and Paul Hannon Jr. are Wally's friends and fellow gang members.
