A physician and old shipmate of Jean-Luc Picard from the USS Stargazer, who in 2399 examines him for a return to space and delivers a grave diagnosis.
Doctor Moritz Benayoun is played by David Paymer in Maps and Legends, the second episode of Star Trek: Picard. He served as a medical officer under Picard on the Stargazer and has remained his friend and doctor in the decades since.
Picard, intending to look for Bruce Maddox and Soji, asks him to certify that he is fit for interstellar service. Benayoun comes to the chateau with the results in person. Picard is in fine shape for his age except for an abnormality in the parietal lobe, of which he was warned long ago.
The doctor explains that it could develop into any of several syndromes, some worse than others, but that all of them end the same way. He offers to pass him anyway, remarking that Picard seems to want to go back into the cold.
