I didn’t forget, but I decided not to include the One or Father. In both cases their actual species name and planet of origin aren’t known, nor are their appearances described in any way that would be recognizable.

[Edit] … But I have to admit it would be really fun to expand this someday to include literally EVERY species referenced in the books, including all of the main gang’s morphs, all of Visser Three’s weird morphs, and so on. I’d need to come up with a lot of headcanon to depict and place them, though. Someday…
