Wally Mack

 is a resident of Vault 101. He is younger than the Lone Wanderer. He is a member of the Tunnel Snakes gang. Mr. Mack is the son of Allen and Gloria Mack. Wally's siblings are Steve and Susie. Butch DeLoria and Paul Hannon Jr. are Wally's friends and fellow gang members.

Wally is highly intelligent, a natural leader, and has a strong opinion on many issues. Even as a young kid, his friend Butch recognizes his intelligent and leadership qualities. However, Wally is very abusive and bullying of those he doesn't like. He is especially abusive of the Lone Wanderer.

In the 2260's, at one of Wally's birthday parties, the robot Andy performs magic tricks and children play Hunt the Mutant on the Atrium.

Later, on July 13, 2268, Wally attends the tenth birthday party of the Lone Wanderer after receiving an invitation from Amata Almodovar. She invited him upon the insistence of the Lone Wanderer's father. During the party, Wally expresses his scorn for the party to the Lone Wanderer's face. Wally believes the Pip-Boy 3000A is antiquated junk and thinks the decorations are for a younger kid. Later at the party, with his closest friends, they discuss possible names for their gang. On August 3, 2274, before the G.O.A.T., Wally and his friends are sexually harassing Amata near the classroom. The Lone Wanderer can side with Amata, side with the Tunnel Snakes, or leave Amata with the Tunnel Snakes.

Wally judges the G.O.A.T. test is pointless and arbitrary, walking out of the class before hearing his teacher's answer to what Wally's future occupation would be.

Later, crisis in Vault 101, Wally can be found living in the Vault 101 Dweller's old room. He reveals that he has left the Tunnel Snakes and claims that his father, Allen, saved Stanley, and insults James for good measure.
