Data

Data was an android and counterpart of the Data of the primary universe in the Mirror Broken offshoot of the mirror universe.

As with his primary universe counterpart, the likeness of Brent Spiner was used for the mirror universe version of Data.

Designed and built by Noonien Soong, Data was working in a mine when Imperial Starfleet officer Jean-Luc Picard recruited him to serve under his command on the ISS Stargazer. By then the Terran Empire was on the verge of defeat at the hands of the more powerful Klingon-Cardassian Alliance. Unlike his primary universe counterpart, this version of Data had no ethical subroutines to keep him from carrying out the orders of his commanding officer.

When Picard became aware of the construction of a new ISS Enterprise (NCC-1701-D), Data assisted Picard in taking control of the vessel from Captain Jellico. He was then assigned to the Enterprise as operations and second officer.
