Star Trek: 10 Top Secret Artefacts At Daystrom Station

Nearly as dismissed as Nemesis itself, the late introduction of Soong prototype B-4 allowed a backdoor escape for Data following his death aboard the Scimitar.

It would be a backdoor that was only pried open some 20 years later midway through the third and final season of Picard but it was there nonetheless. Data's return would be realised through the awakening of the Soong golem, but B-4's remains also made their way there.

Fans will recall that B-4's parts were last seen stored at the Daystrom Institute on Earth when Jean-Luc was investigating the appearance of Dahj Asha. Between then (2399) and the opening of season three (two years later in 2401), B-4 has been moved off planet to the more secure facility where the minds of all of Soong's works have been combined into one entity.

The pre-Lore android's personality never actually resurfaced in Picard although it's interesting to note that the parts used in the show were the same as the ones used in Nemesis itself.

Disassembled once more in the central vault of the Daystrom Station, B-4 unceremoniously sat alongside the more human than human M-5-10 Soong-type creation that would bring back one of Star Trek's most beloved - and missed - characters.
