I notice you don't have an intelligence officer. I'l like to suggest a Founder shape-shifter for the role. A young one, probably in the form of a female, but, of course, adaptable to any form. The shape shifting would be extremely useful in espionage. As a "young" Founder, it would be very interested in exploring new things, as in sexually. I'll place several limitations on its abilities; I don't want to be accused of god-modding (I guess the original Founders were!). I think it's "normal" form would be as a Deltan female in appearance.
If this is acceptable, I'll post the character on that list.
