This article is about the Caretaker of The Great Machine. For the Caretaker of The Great Machine, see: Zathras

"No one ever listens to Zathras. "Quite mad," they say. It is good that Zathras does not mind. Has even grown to like it. Oh, yes."


Zathras is a humanoid of unknown origin who, along with his nine brothers, takes care of the Great Machine on Epsilon III. They are all named Zathras, but with minute differences in pronunciation.[1]


Born in approximately 2150, Zathras grew up with his brothers to become a caretaker of the Great Machine.

He was first encountered on Babylon 4 and again when Jeffrey Sinclair returned to that station with the purpose of stealing it.[2]

By 2260 Zathras, 110 years old, was the oldest living caretaker of the Great Machine. During his many years of working with Varn and then Draal, Zathras had studied the machine. Over the years Zathras became so familiar with the machine that he knew things about the machine that even Draal had not yet learned. Draal was also familiar with Babylon 5 and its personnel, learning much about Ambassador Delenn, Ambassador Sinclair, and Captain John Sheridan.

He stayed behind with Sinclair on the journey back to use Babylon 4 as a base of operations during the last Great War, 1000 years in the past. Once Kosh and Ulkesh were satisfied that Sinclair was who he said he was, and entered a Chrysalis, Zathras began wiping the station systems to remove anything that could pinpoint their origins to safeguard the future.[3]

Although Zathras mostly lived on Epsilon III, helping Draal take care of the Great Machine, the actual homeworld of Zathras' species (along with their own race name) was never revealed.


Though he initially appears as a silly and somewhat clumsy creature, Zathras was very dedicated and loyal to the cause as well as wise and technically proficient. His most repeated phrase is "no one listens to Zathras".

He is depicted as a bit of a simpleton and will tend to talk a lot.
