Holographic Datas.
There have been multiple timelines, alternate realities and parallel universes that have all contained versions of Data, as well as various reproductions and replicants.
Data Soongs[]
Other versions of Data[]
Myriad Universes[]
Data in myriad universes.
- In an alternate timeline where Soong-type android were mass-produced, Data left Starfleet and founded a Soong colony on Turing with his brother Lore. Their adaptation of Iconian technology led to a peaceful, Federation-dominated Milky Way Galaxy. (Myriad Universes - Echoes and Refractions novel: Brave New World)
- In a reality where the Cardassians discovered the Bajoran wormhole, Data left the Enterprise-E to become captain of the USS Sutherland. (Myriad Universes - Echoes and Refractions novel: A Gutted World)
The Last Generation.
- In a timeline where Captain Braxton helped assassinate Federation President Ra-ghoratreii, Data helped create a new timeline where the Federation was not conquered by the Klingon Empire. (TNG - Myriad Universes comic: "The Last Generation")
Picard's death[]
In most timelines where Jean-Luc Picard was killed during his time as Locutus of Borg, Lieutenant Worf, son of Mogh was promoted ahead of Data to first officer. (TNG episode: "Parallels")
In one timeline where Picard had died, Commander Data became William T. Riker's first officer. (TNG novel: Headlong Flight)
Other realities[]
In some versions of reality, the Enterprise-E or other versions of it were commanded by Captain Data or Captain Data Soong. In others, he survived the 2379 encounter with the Scimitar. (TNG novel: Q & A)
Only a torso-less head remained of Data on an Earth conquered by Romulans in the 23rd century. It was hardwired into Geordi La Forge's skull to allow the engineer to see. (TNG comic: "Deviations")
