Least Favorite Character Seven of Nine.... She was quite attractive despite the obvious handicap of being blonde (not into large breasts either).
Favorite Character-Robert Picardo. Robert Picardo didn't play the Doctor, Robert Picardo just told people he was the Doctor and they believed him..... But something negative.....
I think, after losing his freakin mind on more than one occasion, he kinda became a liability of Data-like preportions.
