Lieutenant Picard in an alternate timeline.
Throughout the history of the universe, there have been multiple timelines, alternate realities and parallel universes that have all contained versions of Jean-Luc Picard, as well as various clones and disguises.
In an alternate timeline in which Khan Noonien Singh won the Eugenics Wars and Humanity underwent genetic engineering en masse, Princeps Senior Jean-Luc Picard was the commanding officer of the Earthfleet Dreadnaught-class warship Illustrious in June 2376. Picard, who was known for his cold-blooded nature, was the personal agent of Tiberius Sejanus Singh, the Imperator of the Khanate of Earth. This led him to be dubbed as “the Khan’s Dagger.”

After the discovery of the Botany Bay carrying 87 men and women from 2010 by Princeps Julian Bashir of the Defiance was reported to the Khan, he ordered Picard to rendezvous with the Defiance in order to prevent the Botany Bay crew from revealing the truth about his grandfather Khan Noonien Singh to his followers.

In another reality, Picard was the first officer of the US Enterprise in 2380 while Wesley Crusher was the captain. Miranda Kadohata was the operations manager. The ship had previously been commanded by Edward Jellico, who had made Picard second officer after his work on the survey of Selcundi Drema had brought him to Jellico’s attention. After Data was killed by the Reman usurper Vkruk in 2379, Picard became first officer. In his early career, he had been friends with Captain Crusher’s late father Jack Crusher.
In another reality, Picard was the captain of the USS Stargazer in 2380.

Lt. Cmdr. Data : It was probably unwise of us to attempt to place a human colony in this area. Of course, there are 3,004 other planets in this star cluster in which we could have colonized. The largest and closest.
Lt. Cmdr. Data : Would you choose one life over one thousand, sir?
