Armitage

 is the bodyguard of Dr. Zimmer. While seemingly very human, he is in fact, not. He is one of Zimmer's many androids.

Armitage is armed with an AEP7 Laser Pistol, and wears a Merc Adventurer Outfit. Despite his status as an android, and his claim that he could "snap your neck like a chicken bone", he is of average human durability.

Trivia

 * Armitage is a very common cyberpunk name since William Gibson used it for the Wintermute-controlled mercenary in his 1984 novel Neuromancer. Gibson's work is considered the archetypal cyberpunk novel, and is also the antecedent for the idea of "wired reflexes." Prior games (such as the early 1990s tabletop RPG Shadowrun and its computer-game spinoffs) have also referenced Gibson's cyberpunk world with borrowed concepts and character names.
 * Professor Armitage is a character in H.P. Lovecraft's famous story, "The Dunwich Horror." Although the android-related allusions to "Armitage" are more relevant to Fallout 3, the popularity of the name has its origins in Lovecraft. Also considering the Dunwich Building is a location in Fallout 3, it's not a stretch to perceive a small nod to Lovecraft.
 * Armitage's name may also be a reference to Naomi Armitage (the titular character of the Armitage the Third anime), an android so indistinguishable from a human that she can even have human children.
