In the second season of "Star Trek: Picard," the good admiral (Patrick Stewart) is approached by his old rival, the trickster space deity Q (John de Lanice), about a new challenge. Q snaps his fingers and flings Picard into an alternate universe where Earth had become a galaxy-wide tyrannical power, devoted to the extermination of its perceived enemies. Earth had already driven the Romulans and the Klingons to extinction, and is now gearing up to execute the last-known Borg (Annie Werching). It's pretty grim. Picard, occupying the space of his tyrannical interdimensional counterpart, has to gather his friends (Q conveniently teleports several of them to the evil universe as well), and then travel back in time to the year 2024 to figure out how the evil universe came to be.

At the end of the season, it's revealed that Q only played his little time-travel game with Picard as a sort of wistful farewell.
