For a Fallout savage worlds game I have mostly written up (with 0 realistic plans to run though), the Overseer is a man named Johnathan Wiseau, which due to a stroke part of his face is paralyzed and caused him to slur his words and suffer from Foreign Accent Syndrome.
His Best Friend(tm) is Marcus, the chief maintenance technician, although his job keeps him pretty busy so unfortunately the PCs wouldn't be able to interact much with him.
The overseer's assistant is Denny Hawk (actually no, its Hawks) and lost his parents to cancer when he was really young, and the overseer decided to adopt him as his own. (actually wait, it IS Hawk.)
The medical officer/counselor is named Peter, although he sometimes goes by Steven, and he's always a little paranoid that the nuclear reactor that powers the vault will explode.
The medical officer's nurse is a beautiful woman named Lisa, and shes currently in a relationship with the overseer. Her best friend is the children's teacher, Michelle.
And although the vault corridors are kinda cramped, they still take time off to bond by playing catch with an old football.
