The Shrike Can Shape Shift

If u/socmedisevil's theory is correct, then it wouldn't be the first time fans have seen a ship drastically change shape in the "Star Trek" universe. In Season 3 of "Star Trek: Discovery," Booker's (David Ajala) ship is capable of rearranging itself mid-flight. That, however, is in the year 3188, almost 800 years after the events of "Picard." 

What's more, it's one thing for pieces of a ship to shift around like Booker's, but it's another for a ship to be able to transform like Changelings do. Still, others on the thread agree it's possible. 

"Should be simple for a race who specializes in shape shifting," u/tebower81 posted. Meanwhile, another user, u/ReaperXHanzo, suggested that programmable matter should be able to achieve this; however, that is also something that is not yet achievable in this time period.  

A technological explanation wouldn't necessarily be out of the question either. After all, the Shrike has the capability to teleport itself and torpedoes from enemy ships. The crew of the Titan is utterly baffled by this technology too, meaning that Starfleet may not be familiar with Changeling tech. 

Having the Changelings as a major antagonist in "Picard" solidifies the series' connection specifically to "DS9" lore, broadening it out from "The Next Generation" connections. Easter eggs linking the events of the series to "DS9," as well as "Voyager," have been littered throughout, so there is a chance "Picard" could tie up some stories from these series, or at least expand the lore.
