Officer O'Brian is a member of Vault 101 security in 2277.

Background

Lightly armored and keen to deliver a bit of punishment to the vault civilians, Officer O'Brian is a vicious, unthinking man who delights in the pain of others. The confusion of the Lone Wanderer's escape makes his violent tendencies all the easier to hide.[Non-canon 1][clarification needed]

Officer O'Brian is guarding the locked atrium door to the Vault 101 entrance together with Officer Richards.
