This is something I've been wondering for some time, and this thread has really made me curious, but a question for KRAD...since you are a connoisseur and writer of both...in an ultimate fan-boy crossover, if you could pick any of the various incarnations/regenerations, which Doctor (Who) would you team up with which Trek series and crew???
Well, if I was picking a Doctor to write on general principle, it'd be either Four or Nine, simply because they're my two favorites.
As for which flavor of
Trek, that's tougher. See, the Doctor has the ability (as, I believe, Stephen Moffat his own self once put it, though I may be misattributing) to go from being in the brig/dungeon to being on the bridge/in total control of the situation in 20 minutes or less. The nature of a great deal of
Who fiction (and a
Trek crossover would fall into this category) is that he tends to take over from whoever's nominally in charge. That's harder to do in
Trek fiction, because the captain really is in charge, and it's tough to supersede Kirk or Picard or Sisko or Janeway or Calhoun or Gold or whoever.
So I guess I'd do it with
Enterprise.
