Wally Mack

Wally Mack is one of the inhabitants of Vault 101, a few years older than the Vault 101 Dweller. His father is one of Vault 101's Security Guardsman. He is a member of the Tunnel Snakes gang. He is arrogant and very self-confident, believing he is in fact, the leader of the Tunnel Snakes, not Butch (Butch is even not willing to argue this when confronted). Unlike the other Tunnel Snakes members, who both admit to actually liking the Vault 101 Dweller despite picking on him/her, Wally seems to genuinely dislike him/her. .

Wally managed to figure out the G.O.A.T. test was pointless and arbitrary, walking out of the class before hearing Mr. Brotch's answer to what Wally's future occupation would be. He eventually becomes one of the Vault's guards.
