This question got me to thinking about how there have been many actors who have had several roles across the Star Trek franchise. It seems that once an actor demonstrates good performance in that franchise, it is very likely (at least more so than in other franchises, or it might just be my imagination) that they will be seen as another minor or major character later on.
So, I'm now curious to know which actor has had the most distinct roles in the franchise. Some likely candidates have already been named in the linked thread (e.g.: Majel Barrett, Jeffrey Combs) but I'd like to know if these are really the top ones?
Note that this question is asking about distinct roles. That is, variations of the same character (e.g.: holographic or dream-state representations, shapeshifters or alien possessions, etc.) do not count. I'd also like to exclude very closely related characters (e.g.: ancestors, descendants, similarly-crafted androids, etc. - I was originally going to include these, but then realized that Brent Spiner might be an all-too-easy winner).
Also, to keep this question in an SE-sized scope, I'm only looking to draw from primary-universe live-action productions up to and including ENT. That includes:
- TOS, and related films
- TNG, and related films
- J.J. Abrams' Star Trek universe
- Video Games
