Thomas Brennan

Warden Thomas Brennan was the head of Eastern Regional Penitentiary before the Great War.

Background
Warden Brennan oversaw the transition of the prison from a human-staffed facility into a fully automated penitentiary. All of the prison's staff were replaced with robots, while Brennan stayed until his retirement benefits went into place. Brennan also fitted every prisoner, no matter their crime, with an explosive prisoner collar to prevent escape from the decaying prison. He was eventually replaced by the Warden Mainframe, which is still active as of 2102.

Appearances
Thomas Brennan is mentioned only in Fallout 76.
