1 Balthazar's Angel: Is she in Balthazar's head? Is she part of his programming or a symptom of psychological disorder. Is she real? Why can't anyone else see her? This breathtaking blonde was generous, cruel, absolutely devoted to the one god, and had a perfect vision along with the will to follow it through. Her character, her state of being, even what side she was on, was maintained perfectly from the very first episode to theconclusion of Battlestar Galactica.
2 Data: An android living in a human world. One would think that the subject had been covered after decades of writing and t.v. materials on the subject. But our introduction to Data, attempting to whistle, proved that assumption wrong. Through seven seasons and four movies, Data never stopped showing us what is was like to look at the galaxy through the eyes of an artificial life form. Interviews from the cast and crew have revealed he was responsible for large portions of many episodes and one can truly believe it. When Data died, the movies were over.
3 Dr. Who: The storyline is unique in all of t.v.; a man who travels through time and space, exploring worlds, stopping threats, and correcting the time stream. That inevitably makes the lead interesting. But the lead changes every few years and each actor has brought his own unique characteristics; who can forget Tom Baker's scarf and jellie babies? The ridiculous smile of Christopher Eccleston? The always running David Tennant? characters themselves have been interesting. They are all fun, energetic, and brilliant (except of course for Hartnell, but he was a good introduction to the character). And there is that crazy way they all seem to take the obvious or the smart remark and come up with something brilliant and life-saving.
4 Prot: The lasting image of this "alien" is him grabbing a banana and eating it, unpealed, as a psychologist studies him for some pathology. He threw out one far-fetched explanation after another. It's almost like he doesn't want to be believed. So when we find out he is linked to some poor devil who had suffered an emotional trauma we have every reason to believe he is just a man who has lost his grip. That is, until he disappears on a sun ray
5 Dr. Balthazar: Brilliant, arrogant, a survivor, the president, a religious leader, responsible for the near-annihilation of his race, a sex addict, immoral, unethical - did I mention he was smart and cocky? Whether he was having sex with an angel only he could see, having a dual conversation with only one response to each person's statements, accidentally doing something to help the human race even as he was working only to save his own life, Balthazar was fascinating to watch week after week. To have made his character so intriguing amidst such a spectrum of actors was even more impressive.
6 Paul Atreides: Fated to end an empire and cost millions of lives, watching the struggle between his visions of the future, the political needs of the moment, and his desire to be free of responsibility made for an incredibly rich character. He walked through life knowing how and where each tragedy in his life would take place because he had chosen those events over others in order to ensure the best possible future for his race. His son would completely cut himself off from humanity with his enigmatic "Golden Path, but Paul allowed himself to feel everything.
