A Devore inspector who serves as Kashyk's second-in-command during the repeated searches of Voyager for hidden telepaths in 2375, carrying out the inspections with cold, methodical efficiency.
Prax is a Devore officer seen in the fifth-season Voyager episode Counterpoint, where he is played by J. Patrick McCormack. He serves directly under Inspector Kashyk and leads the armed teams that board Voyager each time the ship is stopped in Devore space.
While Kashyk plays music over the comm system and chats with Captain Janeway in her ready room, Prax does the practical work: lining up the crew, checking the manifest and scanning cargo bays for telepaths, whom the Devore Imperium treats as criminals.
When Kashyk later appears to defect, Prax takes over the pursuit. At the end, after Janeway's ruse leaves the Devore with nothing but empty transporter buffers, Kashyk tells Prax to leave the whole embarrassing incident out of the record.
