B-4 was a Soong-type android created by Noonian Soong. He was one of three failed prototypes before the construction of Lore was successful. Although B-4 was outwardly identical to both Data and Lore, the two final androids built, B-4 was not equipped with a positronic brain as sophisticated as those of his brothers.
The existence of B-4 was not known to Starfleet until 2380, when the disassembled pieces of the android were found by the crew of the USS Enterprise-E on Kolarus III. The pieces had been planted there by Shinzon as part of an elaborate scheme to lure Jean-Luc Picard near Romulus in order to capture him. B-4 was also used as an unwitting spy; he was equipped with a second memory port that contained subversive programming that compelled him to download vital data about the positions of all Federation starships and their coded communications frequencies.
Although he recognized B-4's limitations, Data wished to give his brother the opportunity to expand his capabilities, much in the same way that he himself had in years past. Towards that end, Data willingly copied all of his memories to B-4, hoping that the added experiences would help B-4 to expand beyond his original programming. However, soon afterward, B-4 had to be deactivated because of the danger he posed to the Enterprise crew, as a result of Shinzon's tampering.
A short time later, Data was killed while destroying the Scimitar, having voluntarily sacrificed himself to save his crewmates. B-4 was reactivated so that Picard could tell him of his brother's death, but Picard sadly departed the meeting when his attempts to explain what Data meant to them only confused B-4. Although some of Data's memories began to surface as Picard left the android in his ready room, B-4 beginning to sing the song that Data had sung at Riker and Troi's wedding shortly before B-4's discovery, his future was uncertain.
