The Custodian

The Custodian is a protectron in the Big MT west tunnel in 2281.

Background
The Custodian is a unique protectron found in the Big MT west tunnel, along with some leveled MK series protectrons. The Custodian is the automated janitor for the train tunnel (complete with dust mop) and perhaps the train system itself. However, after Elijah wrecked the train system, it and the other protectrons became trapped inside.

Bugs

 * The Custodian (much like all of the Big MT protectrons) lacks the DT actor effect (+8 DT) possessed by normal protectrons.

Appearances
The Custodian appears only in the Fallout: New Vegas add-on Old World Blues.
