 Thus far, all five Star Trek series have featured at least one  character who is the first of their species in Starfleet. In Voyager  there are two: the holographic Doctor (EMH), and Icheb  (Brunali/Borg). Neelix (Talaxian), Kes (Ocampan) and Seven of Nine  (Human/Borg) also served specific functions on the ship, but were  never formally inducted.
