I am guilty of owning more dolls in my Star Trek collection. Here is the Next Generation set.
You may notice that I still have work to do. No Commander Data… No Geordy La Forge… No Wesley Crusher (if such a doll even exists)… These figures are all dressed for a TNG movie that practically nobody liked.
I also have two Star Trek Voyager dolls, Captain Janeway and Seven of Nine.
It is probable that no other figures from this series exist in twelve inches.
Captain Sisko is the only figure I have ever seen for Deep Space Nine, though I have a suspicion that more exist, at least the female crew members, and maybe that wonderfully devious Ferengi Quark.

Greetings. What is the name of the company that manufactured the Troi, Riker, Picard and Wolf dolls please? Can you tell me what year they were manufactured? Are these American or foreign?
http://www.playmatestoys.com Those figures were copyrighted in 1998 and released as a tie-in with the movie Star Trek : Insurrection. I believe the company is in both America and Japan, at least their factories are.
Thanks for taking the time to respond. Much appreciated! 🖖😁
