Jet Manhaver is an ambitious Cerritos officer who fills Boimler's old position and clashes with Mariner during a dangerous away mission.
Jet Manhaver is a competitive human officer aboard the USS Cerritos who once dated Barbara Brinson. In Kayshon, His Eyes Open, he takes over Boimler's position after Boimler transfers to the Titan, making Mariner feel threatened, and joins her, Tendi, Rutherford and the new security chief Kayshon on a mission to catalogue a dead collector's estate.
When the estate's automated defenses attack, Jet and Mariner argue over how to escape, until both realize they need to let Rutherford and Tendi take charge, and the team returns safely. Jet was voiced by Marcus Henderson.
