TOS - Scotty

TNG - Ro Laren or Riker

DS9 - O'Brien

Voyager - Chakotay

Enterprise - Isn't there a dog on it? Yeah, the dog.

You are thinking of Captain Archer's dog Porthos. Named after The Three Musketeers.

Hmmm...

TOS - Kirk of course.
TNG - Data I spose... hated everyone else (specially that No. 2 Riker)
DS9 - Dax - Jadzia and Mirror Ezri.
Voy - Lon Suder... (Basics 1+2) - Starfleet could use more like this guy!
Voy - Seven.
Ent - Archer + T'Pol - equal
Abrams - Pike - Very Inspiring character... I would join the girl guides if he told me to!
Abrams - Bones - Karl Urban pwned that role and cracked me up all through the movie.
Bab - Jon Sheridan - ooops wrong show!!

TOS: Kirk

TOS: Spock

TOS: McCoy

TOS: Sulu

TOS: Chekov

TOS: Uhura

TOS: Scotty

TOS: Chapel

TOS: Rand

last summer's little misadventure: McCoy, because Karl Urban was channeling DeForest Kelley

Speaking of recurring bit-characters, there was also a dark-haired yeoman that sometimes showed up in the series, she had a similar hairstyle to Rand's I think. >.>

TOS: Bones
TNG: Bev Crusher - prize for most beautiful woman on TV ever
DSN: Kira
Voyager: Janeway
Enterprise: a tie between: the closing credits and the guy who cancelled the series

TOS: Bones
Enterprise: Trip
Voyager: Doctor
TNG: Q
DS9: Martok

All three of them?

After thinking about it, Im changing my vote to Bones. While I like Spock, I loved Bone's crusty attitude; probly in part why I like House.

Did anyone else cry when they learned Kelley had died?

TOS: Toss up between Bones and Scotty
Reboot: Bones
TNG: Data
DS9: Dax (any and all of them)

Haven't watched VOY or ENT.
