The Emergency Medical Android
The Emergency Medical Android was a character from The Voyager Encounter simulation in the Museum of Kyrian Heritage.
In this simulation, the "EMA" developed biogenic weapons during the Vaskan-Kyrian war and tortured prisoners with a neural solvent to gain tactical information for the warship Voyager.
After the EMH backup module was discovered in 3074 and The Doctor activated, the simple fact of his holographic nature was enough to make Quarren question what he thought he had known about Voyager. This doubt ultimately led to The Doctor debunking the utterly inaccurate revisionist history the simulation taught. (VOY: "Living Witness")
The outer appearance of the EMA was quite similar to the EMH, except for the yellow hue of its eyes, comparable to fellow android Lieutenant Commander Data, and quiet mechanical sounds when it moved.
Like the EMH, the EMA was portrayed by Robert Picardo.
