Moore (Fallout)

Moore was one of the four psykers, along with Gideon, Wiggum, and Lucy, that was kept behind a forcefield in the Master's Lair beneath the Cathedral. Presumably, he was one of the Master's failed experiments in trying to awaken psychic powers in humans, as Moore was quite clearly insane. Described as a "scruffy looking fellow", and wearing a Psychic Nullifier, Moore proved to be quite unintelligible when the Vault Dweller encountered him. The only useful information he had provided was that "Gideon speaks the way", with regards to the Vault Dweller reaching the Master himself. It can be assumed that Moore died with the destruction of the Cathedral.

According to the Fallout Bible 3 by Chris Avellone, Moore was a pyrokinetic-dominant psyker. These powers were apparently suppressed when Moore was fitted with a psychic nullifier.
