Harkness

Harkness, also known as A3-21, is the 35-year old Android, and is Rivet City's security chief in the year 2277.

Background
Harkness is an android, made in the year 2242. He escaped the Commonwealth to live his own life, but, because of the Synth Retention Bureau, he needed to get a new face and memory. After some searching he found Horace Pinkerton, a skilled surgeon that agreed to perform the facial construction surgery and memory swap needed for Harkness to begin his new life. After this, he got a job at Rivet City as security chief.

Daily schedule
During the day, Harkness can be found outside Flak 'N Shrapnel's weapon store in the Rivet City marketplace. He can also be located on the top floor of the Bridge Tower from 12:00 Midnight to 6:00AM.

Interactions with the player character
He is the first person you encounter upon finding Rivet City. He will demand that you state your purpose in Rivet City before he allows you to enter. With the right options he'll let you in. When you are doing The Replicated Man quest you can convince Harkness that he is an android, or tell Zimmer that he's the android and he will walk off with Zimmer back to the Commonwealth. If you are on Harkness' side, you can get him to kill Zimmer and Armitage or ask if you can do it yourself. After this is completed he will give you the A3-21's Plasma Rifle.

Related quests
Harkness is hunted by Dr. Zimmer, from the Commonwealth, who will pay well for his return.

He is considered a plot-critical NPC, and thus cannot be killed until this quest is complete. Before that, he can only be knocked out. Harkness remains an essential character even after The Replicated Man is completed, although this may be a bug caused by acquiring both rewards or neither for the quest (by obtaining the rewards from Harkness and Zimmer, then killing Zimmer to prevent him from taking Harkness). If you help him by killing Zimmer, he will award you with the A3-21's Plasma Rifle (A3-21 being his android name). You can also gain the Plasma Rifle by telling Harkness the truth.

Quotes
"I never should've let you on this damn boat!" "Everyone's so goddamn trigger happy these days." "We've got ourselves a psychopath. Everyone stand clear!" "You're just pissing me off!"

Appearances
appears only in Fallout 3.

Behind the scenes

 * When prompted with his activation code, Harkness will mention all of the 'runners' he killed. Along with the Snatcher reference from Gibson, this is a reference to Blade Runner/Do Androids Dream of Electric Sheep?.

Bugs

 * Harkness may end up permanently stuck in his initial position. This happens if the player either completes the quest Tranquility Lane without going to Rivet City beforehand, if the player answers "Forget it..." in their initial dialogue with Harkness, or if the player answers "I'm looking for history on Rivet City" for the Wasteland Survival Guide in their initial dialogue. He may still be interacted with if this happens.
 * Harkness can be pushed off the deck of Rivet City. When he lands in the water, he is stuck there and never returns to his post, although all the normal dialogue options remain. Moreover, if you speak to Commander Lana Danvers sometime afterwards, she tells the player that she has assumed head of security now that Harkness is gone. This has happened on the PS3 version, after both the Scientific Pursuits and The Replicated Man quests. (Confirmed PC and Xbox 360 version)
 * If you complete the Replicated Man quest by telling him he is an android and letting him kill Dr. Zimmer, he may stand in Rivet City Market permanently in the same spot.
 * If you instead complete the Replicated Man quest by informing Zimmer, but manage to kill Zimmer before he leaves with the android, Harkness will stay in Rivet City. His dialogue will be reset to answering as his android name, but he will from time to time be seen at his regular posts, at least once trying to stand in the same spot as Danvers. Occasionally, he will engage in conversation with Danvers when they are both in the market.
 * Harkness may spawn below the entrance of Rivet City, although this may have happened because an enemy attacked him.
