TOS: Chekov, Uhura, Sulu
TNG: Pulaski, Wesley, Yar
DS9: Jadzia, Bashir, Keiko, Kira (sometimes)
VOY: Kim, Janeway, Chakotay
ENT: Trip, Phlox, Mayweather,
Abramsverse: Uhura, Chekov, Scotty
I don't think several of these qualify as "Loved Trek Characters"...
Kim? Wesley? Chakotay? Pulaski?
You may have a point with Wesley, but based on some responses I have seen on this site, the rest seem to have a following, if a cultish one.
