“Organics fear us. We wish to understand, not incite.”

Legion is the name taken by the gestalt consciousness formed by 1,183 geth programs inhabiting a unique geth "mobile platform". The name was chosen at EDI's suggestion. Legion has been searching the galaxy for Commander Shepard ever since the Battle of the Citadel.

Legion is voiced by D.C. Douglas.

Legion is a unique geth mobile platform, designed to operate outside the Perseus Veil and interact with organics directly. To that purpose, it houses 1,183 geth programs, as opposed to the one hundred in other platforms, enabling it to operate independently and speak. Appearance wise, Legion presented an opportunity to develop the basic geth design by adding moving parts that allowed it to animate with detailed expressions. The flaps on Legion's head serve the same purpose as eyebrows to form expression, raising to imply surprise or interest and folding forward much like the furrowing of the brow to show concentration.

It was created and dispatched following Commander Shepard's destruction of the Old Machine "Nazara", known to the rest of the galaxy as the Reaper Sovereign, investigating several of the worlds Shepard visited — Eden Prime, Therum, Feros, Noveria, Virmire, Ilos, and a dozen uncharted worlds. Eventually it found the Normandy's crash site on the planet Alchera, salvaging a piece of Shepard's N7 armor and incorporating it into itself to repair damage sustained on Eden Prime after being shot by Alliance soldiers. If questioned about specifically using Shepard's N7 armour to repair itself, Legion becomes evasive, first rationalizing with "there was a hole" and then states "no data available" after being pressed, suggesting that it was the result of an irrational action, which goes against the concept that every action the geth do is the result of calculation, unaffected by emotion.

Legion is first encountered while searching for the IFF on the derelict Reaper. It is surprised to find Commander Shepard (to whom it refers as Shepard-Commander) alive, but assists Shepard's team against the husks roaming the dead ship. Eventually, it is knocked out by a husk while opening the way for them to reach the ship's mass effect core. If recovered, it can be sold to Cerberus for research (as intact geth are hard to come by), or brought aboard the Normandy SR-2 and stored under guard in the ship's AI Core. It can then be reactivated for Shepard to interrogate it.


When the geth does not appear to be hostile, it expresses its wish to help Shepard's mission, at which point it will join Shepard's team. When Shepard asks the geth its name, it simply states "Geth". Not satisfied, the Commander rephrases the question until EDI steps in and, referring to the number of programs active in the single mobile platform, quotes a passage from Mark 5:9 in the New Testament — "My name is Legion: for we are many". The geth believes this to be an "appropriate metaphor" and thus becomes known as Legion.

Legion speaks in a straight-forward and robotic fashion, often answering with single words. When using whole sentences its word structure is very organized. Legion regards itself not as a single being, but as a gestalt entity which must achieve consensus to act. Legion expresses admiration for EDI, because unlike the geth who are made up of different processes that rely on each other, EDI handles all the functions on the Normandy by herself, though it also questions how she manages to maintain stability. Legion occasionally expresses its disapproval of how EDI's activities and development are shackled aboard the Normandy.

Legion can, if asked, give more insight into the geth, and often expresses interest in philosophical questions. It also discusses the geth-quarian war, referring to them politely as "creators", which is also how it addresses Tali and some quarians the squad encounter. Legion will, if prompted by Shepard, play back an audio recording from the geth collective memory, in which an early geth haltingly asks its quarian master whether or not it has a soul, an event mentioned by Tali in the original Mass Effect. Legion clarifies that this wasn't the first time a geth had asked the question, but it was the first time it frightened the quarians.

After a while, Legion will inform Shepard that geth are actually apathetic towards organics. Those geth fighting organics are "heretics" following the Reapers or, as they call them, "The Old Machines". Legion will explain that the heretics are developing a virus that will turn all geth into followers of the Reapers and asks you to head to an old, heretic-held quarian space station in order to destroy the virus threatening the peaceful geth. Shepard later discovers this virus could have another purpose: rewriting the hostile heretics to peacefully rejoin the geth.

After both Legion's and Tali's loyalty missions are completed, they confront each other over the quarians' development of anti-geth weapons in preparation for war. Unless a Charm / Intimidate choice is used, one of them will lose their loyalty. Note that if the initial Charm / Intimidate option is greyed out, or if Shepard sides with Tali, there is a Renegade and a Paragon dialogue option that will restore Legion's loyalty and vice versa.


  • Specifically, Legion's name comes from a passage in the Gospel of Mark, in the New Testament of the Bible. In the passage Jesus was traveling when he came across a man possessed by demons. When Jesus asked the man his name, the demons within him responded "My name is Legion, for we are many". The demons begged Jesus to send them into a nearby herd of pigs instead of sending them away. Jesus did so, and the demons made the pigs charge off a nearby cliff and die.
  • From time to time, Legion will do the Robot as one of its idle animations.[1] This can happen in both the AI Core and on missions where Legion is in the Commander's squad.
  • Shepard's N7 armor was originally added to the design concept just for fun, but has now become an integral part of Legion's appearance and back story.
  • Earlier in ME2's development Legion's acquisition mission was not part of the critical path, and could occur earlier in the game. Only later was it decided to fold the Reaper IFF into Legion's acquisition. This required only slight rewrites to the existing mission aboard the derelict Reaper. Evidence of this earlier design lies in Legion's unique dialogue lines for places like Purgatory, which can be heard if one uses save file modification and brings Legion along for the mission.
  • Legion claims that Shepard encountered Sovereign on Ilos during the first game, even though this encounter actually happened on Virmire. It's uncertain whether this is a writing error, or if Legion simply has wrong information about the occurrence.
  • Legion, as a character, may be a reference to One of Many, a companion who can be gained in Neverwinter Nights 2: Mask of the Betrayer. One of Many is an embodiment of countless undead souls combined into a single sentient being, similar to the amalgam of programs that make up Legion. One of Many, being undead, is seen as an enemy to many characters of the game, like Legion, and shares some less than positive interactions with other companions.
  • Legion possesses a single antenna-like attachment on its left shoulder, a trait shared with large bipedal geth units, such as the Juggernaut, who have two (one on each shoulder), but which is absent in man-sized ones, such as the Shock Trooper. Although its exact function has yet to be revealed, it likely exists to emphasise the uniqueness of its mobile platform.
  • Curiously, at one point during the suicide mission Legion refers to itself as "I" rather than "we" if you choose it as a tech specialist. This may simply be a script error, as Legion refers to itself as "we" all other times.
  • It is possible to see Legion before its first cutscene. After the two husks are killed by an unknown sniper on the derelict Reaper, if you look around in the back of the room the shots came from, Legion can be seen standing on the ledge at the back. It will walk away slowly once you enter the room.
  • As with all squad members, Legion has unique dialogue that can be heard at various locations, during missions or assignments, or if a specific squad member is in the selected team.
  • The Shadow Broker has files on Legion which can be accessed aboard his ship.
