This page is about the original version that appears in Fallout: New Vegas. For the cloned model that appears in the Fallout: New Vegas add-on Lonesome Road, see ED-E (Lonesome Road). For an overview of eyebots in the Fallout series, see eyebot.
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 a courier of the Mojave Express and delivered to Johnson Nash. Unable to repair it himself, Nash left ED-E to languish on Primm's branch office counter, where it remained while Primm was taken over by escaped convicts. When the Courier arrives in Primm, he/she is able to repair ED-E, allowing it to join the Courier's quest as a 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.
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 is available in the Mojave before Lonesome Road is begun. In addition, ED-E can be upgraded by finding five circuit boards in the add-on:
Rank 1 - Weapon Maintenance Function: Access to a daily dialogue option allowing ED-E to instantly restore your currently equipped weapon's condition by 25%.
Rank 2 - Energy/Microfusion Cell Production: Access to a daily dialogue option allowing ED-E to produce a number of energy and microfusion cells for you. Also, through dialogue and skill checks, ED-E can 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%.
ED-E remained forgotten in the shop of Johnson Nash, until it was repaired by another courier who let it continue on its journey to Navarro. ED-E was eventually discovered by the Followers of the Apocalypse who managed to recover vast databanks of scientific knowledge.
With its logs cleared and its systems upgraded ED-E remained a vigilant and constant companion to the Courier. The Brotherhood used the information recovered from ED-E to create a small army of Duraframe eyebots.
With its logs cleared and its systems upgraded ED-E is discovered by a traveling caravan, who take him on as a protector as they wander the wastes. The Followers of the Apocalypse used the information recovered from ED-E on Poseidon Energy, to develop new methods to harness the energy of the sun.

When first encountered ED-E has a bumper sticker on its right side saying "My child is an HONOR STUDENT at Roosevelt Academy," which is a location in Fallout 3. On the opposite side from the bumper sticker is a "Great Midwest" Illinois 2062 license plate reading "2ED-E59". The numbers are more worn and faded than the letters, so a quick glance makes it appear to read "ED-E". This is elaborated on in Lonesome Road, where the duplicate version mentions that the original had to stop in Chicago, Illinois for repairs.
Regardless of who upgrades it, ED-E's appearance will be altered. If upgraded by the Followers, the armor will remain the same, but its zapper will slightly change, shooting light blue projectiles instead of the standard red laser. If upgraded by the Brotherhood, it will result in ED-E having a much cleaner appearance, signifying its improved armor. Both upgrades will remove all of ED-E's stickers and the license plate.
ED-E behaves like a human in pathfinding, which means it can set off traps (and can even be knocked down by the Ranger Takedown) even though it hovers.
ED-E does not have much HP to start with. When it is upgraded, however, it will have more than most other companions.
Since ED-E is a robot, it is not affected by poison.
If ED-E is ever frenzied, it will become hostile if dismissed as a companion and returned to Primm. The only exception is if it is sent to be upgraded.
After having completed the game and the "ED-E My Love" quest, ED-E will give an account of what happened after the events of the game; however, its account is given using its signature beeps, so you need to have general subtitles enabled to understand them.
ED-E might strafe side-to-side if multiple enemies are in sight. Although it seems tactical, it won't help if the enemies have firearms.
Even though ED-E is a robot, you can still heal it with stimpaks.
Many non-player characters will express their attitudes toward ED-E upon seeing it. For example, legionaries will express their discomfort around it, Boomers will want to examine it further, Fiends will mutter "A flying robot...man, I must be fucked up...." believing ED-E to be a drug fueled hallucination, and the owners of the Atomic Wrangler Casino will find it strange.
In the E3 2010 Trailer which shows ED-E being shot by a unseen raider, the first shot knocks off his license plate, though when found in game he still has the license plate attached. It may have been reattached by Johnson Nash, or the person who found ED-E, while searching for its parts along the road.
ED-E's character arc was designed by Alik Hooper.
ps3xbox360 If you travel to Big MT without completing ED-E My Love, the Followers option may never appear.
xbox360ps3pc When exiting Bloodborne Cave and Vault 22, ED-E may get stuck in the opening of the cave. In the latest patch, ED-E will instead show up as a marker, but can't be found in the surroundings or in the cave.
ps3xbox360 When at Black Mountain, it is possible that ED-E will disappear after the player is attacked by super mutants in the small pass with the bear traps and the large boulder. It can also happen in the entrance of Vault 22. This might be fixed by going to Sierra Madre (and starting the Dead Money add-on) or by using one of the companion dismissal terminals loaded by the patch released just before the release of Old World Blues. When dismissed via the terminal, there will be a message saying that ED-E has returned to Primm.
xbox360 After upgrading ED-E's armor, its inventory weight goes up from 1 to 2. Traveling to the Fort and back with ED-E as a companion permanently adds an additional 2 to its weight EACH time you go there, eventually making it impossible to place items in its inventory. There is no known way to remove this invisible item weight, and the only way to prevent it is by dismissing ED-E before traveling there. Telling it to wait elsewhere before going to the Fort still adds the extra phantom weight. Apparently, its laser is being duplicated each time your weapons are forcibly removed at the Fort. Even if you enter the Fort without invitation, or the enter with proper Legion reputation (i.e. bad rep, not giving weapons), this may happen.
ps3pc After upgrading ED-E's weapon system, if it is destroyed, the dialogue and text about losing its perk after its death will not appear at all. You can lose ED-E without noticing its death in battles or if it strays too far from the player by its own way being in [DANGER] mode because of the hostiles around it. A related bug exists where if ED-E is destroyed, its perk still remains in the player's Pip-Boy and still fully working. This can be fixed by using console commands prid <ref_id>; moveto player; disable; resurrect; enable where "ref_id" is set for specific ED-E type.
pcps3xbox360 The upgraded weapon system from the Followers of the Apocalypse upgrade can be lost at random, particularly in casinos or in Caesar's Fort. It is actually two different weapons: Energy Zap(00166B94) and Electrical Zap(001694DF), and can be restored with AddItem after targeting ED-E. They require energy cell ammunition (00078CC2), but don't actually consume it.
xbox360 It is possible for ED-E (after the armor upgrade) to not use its weapons and not even move. If you fast-travel or use the wait command, it will rejoin you.
xbox360 Sometimes while speaking to ED-E, a gunfire sound will trigger instead of the regular beeping noise.
ps3xbox360 ED-E may occasionally lose the dialogue option for his daily repair, even after waiting 24 hours. To fix this, travel to The Divide and back and the option should reappear.
xbox360pc Sometimes, without having finished ED-E My Love, he will sometimes use his upgrade (from the Followers) even though he hasn't been upgraded yet. He appears to switch between his original and upgraded gun. There is no known fix.
xbox360pc Occasionally when you fast travel, ED-E loses anything you have put in his inventory. ED-E may also lose unique weapons.
ps3xbox360 ED-E may randomly attack friendly AIs for no reason.
