Following on the heels of Star Trek: Strange New Worlds season 2, it's time for more fun with the crew of the U.S.S. Cerritos in Star Trek: Lower Decks season 4.

After two members of the Cerritos cast appeared in a crossover episode with Strange New Worlds, sending the animated characters from their timeline to that of the U.S.S. Enterprise centuries earlier, this season on the animated series will see the crew of the Cerritos have an interaction with the U.S.S. Voyager. We can only imagine what fun adventures will come from it.
