Allen Mack

Allen Mack is one of many Macks, which live in Vault 101. He is the father of Wally Mack. When the Vault 101 Dweller is escaping the Vault, Allen slams on the window of his vault room, calling for the guards and saying that everything is the Vault 101 Dweller and James's fault. You can see Gloria Mack sitting at a table behind Allen, with her hand on her head.

If the player killed the Overseer during their initial escape, Allen will be elected the new Overseer who is even more oppressive than the previous one and cannot be reasoned with.

One of his combat lines include "The Overseer will hear about this!" even after he becomes the Overseer himself should you happen to have Amata's dad killed, obviously a tidbit of inconsistence. (Unless he's forgetful, or likes to speak in third person)
