wasn't there an albino Klingon? He might have been from a novel, which I guess from reading these threads isn't canon. Can't remember which novel it was though (I've read so many).
The Albino from "Blood Oath" was mentioned above, but you're probably thinking of "Bernie," a dwarf-albino Klingon-human hybrid from Peter David's first run of Star Trek
comics from DC. When PAD was required to abandon that storyline in the comic, he resolved it in the TNG novel Strike Zone
, in which Bernie (implicitly) reappeared as Ambassador Kobry.
