You're right. Evil Harry, or Kymble, was a hypochondriac Trill. The other characters were....
The Doctor - a hologram who had his rights violated by everyone with the slighest provocation
Captain Jenkins - (Janeway) - a warlike, highly unethical Human
Katanay - (Chakotay) - a Bajoran thug with a tattoo of a Bajoran dragon on his cheek
Torrey - (Torres) - a rude Human
Marseilles - (Paris) - a Human who, despite being married to Torrey, was a rampant womanizer
Tulak - (Tuvok) - an aggressive Human with a goatee
Three of Eight - (Seven of Nine) - a Human freed from the Borg Collective who was the only crewmember to side with the Doctor
Neelix didn't have a counterpart. That might be why he was the only one who praised The Doctor's writing.
