I'll try to keep the list within reason: TOS: Spock, McCoy, Scotty TNG: Picard, Data, Troi, Spot (a request from Mrs. Blueshirt) DS9: Bashir, Kira, Quark, Garak (all of them, really; the ones I name can't be separated from how well they play off the other characters) VOY: Seven, the Doctor, Tuvok ENT: Phlox Antagonists: Q, Dukat, Weyoun, Toreth
In no particular order: Reed, Riker, Spock (Nimoy), Guinan, Bones (both versions), Kirk (both, but especially Pine), Damar, Dukat, Kira, Picard.
To be a bit fairer than I normally am I'm going to pick 2 from each series otherwise I'd just pick the cast from TOS. 1. Archer 2. T'Pol 3. Kirk 4. Spock 5. Picard 6. Data 7. Sisko 8. Worf 9. Janeway 10. EMH That was difficult.
I've watched all TOS, movies I-VI, XI-XII, & a smattering of YouTube TNG Clips, so, in true order, here goes: (BTW, unless otherwise specified, all TOS characters are just that: TOS characters.) 1.) Spock 2.) Kirk 3.) Bones (Nu- & Prime) 4.) Uhura 5.) Sulu 6.) Scottie 7.) Data 8.) Picard 9.) Khan (Nu- & Prime) 10.) Spot (SO CUTE!)
In no particular order: TOS: Scotty, McCoy, Kirk TNG: Picard, Worf DS9: O'Brien, Sisko, Jadzia Dax, Garak, Kira VOY: EMH ENT: Chef
