How many multi-episode characters died in Star Trek?

[Starglider]

Sort of up in the air, but what about Gul Dukhat? Did he really die? Or just go to hell or some nonsense? It's been awhile since I last saw the DS9 finale.

Not sure, but Kai Winn definitely died on camera.

Sisko asks if he's dead, and the Prophets say he's "where he belongs, with the Pah-Wraiths". So I guess he's still alive, for a given value of "alive".

[Captain Seafort]

another minor nitpick, but I don't think Sloan ever said he was the director of Section 31 did he?

He called himself "Director Sloan", but he never clarified whether he was the Director or merely a Director, so the answer to your question is "no".

Probably "alive" in the same way Sisko's "alive".

Lupaza and Furel, two of Kira's old resistance comrades appeared at least twice and were both killed in The Darkness and the Light by bomb. Weyoun could also be considered as well. While he may have come back from death in the past, by his WYLB death it was clear that he could not be replaced.

Edit: Also, one of the Red Squad cadets who appeared in DS9 Homefront reappeared and was killed on the Valiant when it was destroyed.

Edit 2: Trip.

[Skylon]

I can't believe nobody thought of Sarek.

Also:

David Marcus (Kirk's son....two films).
Commander Remmick (TNG...appeared in season 1...later turned out to be the host of an alien parasite and was fried awesomely for 80's TV).

Does Trips death in Riker's holosuite count?

[open_sketchbook]

Obviously not; at no point did Next Generation but in on the finale of my favorite Trek and ruin it for me, so your question is clearly nonesense.

[Lonestar]

Weyoun

[Skylon]

Data

And, of course, Lore. He might be the most recurring TNG to be killed off, lasting a handful of episodes and most the show's years.

I dunno if I'd call him killed. Wasn't he just turned off and disassembled, making it easy for a possible return?

[Drooling Iguana]

Edit 2: Trip.

Personally, I consider that entire episode to have been based of false records created to cover up Reed's recruitment of Trip into Section 31.

I consider the entire series to be the product of a daydream patrick Duffy had while taking a shower.

Spock died and came back to live and thus is prohibited by the OP.

Kirk never died; he just went to the nexus.

But he left the nexus and later killed.

Yes indeed. Which is why he counts. Unlike Spock, who died of radiation poisoning in St II and was regenerated back to life by the Genesis effect. Hence why he doesn't count according to he OPs rules.

Mr. Leslie.

[Patrick Degan]

Mr. Leslie.

Hmmmm... Kinda iffy. Mr. Leslie appeared to be one of the casualties on Argus X in "Obsessoin", but in the third season we definitely see him on the Enterprise and still being addressed as "Mr. Leslie".
