Geth VI

The Geth VI is a virtual intelligence created by the geth to study the Reapers if Legion did not survive the suicide mission, was sold to Cerberus or was never activated. It is encountered during the mission to disable a geth dreadnought.

The Geth VI was constructed in Legion's likeness and contains memories identical to Legion's, with the exception of all data on events occurring after Saren Arterius's assault on Eden Prime. Non-standard elements of the Geth VI's armor, such as Commander Shepard's N7 armor shoulder piece and the hole in the geth's torso, are recreated via hologram. While Shepard insists on calling it Legion, it repeatedly affirms that it is not the same entity. The Geth VI is notably less friendly toward Shepard than Legion had been, and states that it cannot understand why Legion had befriended an organic such as Shepard.

The Rannoch campaign can end in one of two ways if the Geth VI is present, and a peaceful outcome is not possible. If Shepard chooses to let the geth die, the quarians will emerge victorious over the geth fleet and the Geth VI will claim that the geth's decision to trust organics was a mistake. If Shepard chooses to upload the Reaper code and save the geth, then Geth VI dissolves itself into the consensus to achieve true intelligence for all other geth. The upgraded geth then emerge victorious over the quarian fleet.
