ED-E

Eyebot Duraframe Subject E, more commonly known as ED-E (pronounced "Eddie" by some and "E-D-E" by others) is a Duraframe eyebot and possible companion in 2281. It is first found in defunct state at the Nash residence in Primm.

Background
ED-E is an Enclave eyebot from the East Coast, built by Whitley at Adams Air Force Base. ED-E is a prototype "duraframe" model. ED-E and its fellows in The Divide have been enhanced for regular combat as opposed to the original model, which functioned primarily as a mobile radio transmitter. However, since the war of 2277, when the Enclave necessitated an increased production of the Hellfire armor, eyebot production was halted, making ED-E the last known surviving model.

At Adams Air Force Base, Whitley uploaded an enormous amount of valuable data on Poseidon Energy and his duraframe research into ED-E's logs, then dispatched it on a cross-country journey to Navarro, past Rockville, Hagerstown, The Pitt, Denver, Nephi, Zion Canyon, Caliente, the Hub, Necropolis, Lost Hills, and San Francisco.

ED-E's first stop was a hidden Enclave outpost in Chicago for upgrades and repairs. It then traveled across the Mojave Wasteland, where it was shot twice by an unidentified sniper, dealing a large amount of damage. This eventually left it deactivated near Primm, where it was found and taken in by an unnamed courier of the Mojave Express and delivered to Johnson Nash. Unable to repair it himself, Nash left ED-E to languish on the Primm's branch office counter, where it remained ignored as escaped convicts took over the town. When the Courier arrives in Primm, they are able to repair ED-E and, in turn, it becomes their companion.

Although ED-E still retains all of its data and understanding of its mission, its internal positioning hardware is badly damaged. The only reason it has not been seized by interested parties is because ED-E has not communicated its special mission to anyone.

Quests

 * ED-E My Love: Once ED-E's logs are discovered, the Brotherhood of Steel and the Followers of the Apocalypse will express interest in it, offering upgrades in exchange for its data.
 * Lonesome Road add-on: A copied, mass-produced version of the original ED-E, still retaining all its memories of the Courier and its own mission, is found in The Divide and is needed to advance through almost all the quests there.

Other interactions
When first found in the Nash residence at Primm, ED-E is broken and lying on a counter. It can be repaired by having one of the following:
 * A Repair skill of 65.
 * A Science skill of 55, with a subsequent Repair skill of 35.
 * Three pieces of scrap metal, two sensor modules, and one scrap electronics.

Lonesome Road

 * With the Lonesome Road add-on installed, ED-E can be used to create items as if it were a workbench or reloading bench, through dialogue. This option will already be available even before Lonesome Road has begun.
 * ED-E can be further upgraded by finding five circuit boards in the Divide:
 * Rank 1 - Weapon maintenance function: Access to a daily dialogue option allowing ED-E to instantly restore the condition of the Courier's currently equipped weapon by 25%. (This can be increased to 35% with skill check, after obtaining rank 2).
 * Rank 2 - Energy/microfusion cell production: Access to a daily dialogue option allowing ED-E to produce a number of energy and microfusion cells. Also, through dialogue and skill checks, ED-E can produce more cells per prompt, or be made to produce flamer fuel or satchel charges (which share the same once-per-day cooldown as the energy and microfusion cells).
 * Rank 3 - Increased DT: +2 DT for both the Courier and ED-E.
 * Rank 4 - Beam damage bonus: +5 to beam weapon damage; affects the same list of weapons affected by the Laser Commander perk.
 * Rank 5 - V.A.T.S. accuracy bonus: Chance to hit targets in V.A.T.S. increased by 5%.

Appearances
ED-E appears in Fallout: New Vegas, and on the cover of All Roads. A duplicate of ED-E also appears in Lonesome Road as a companion.
