Tik-Tok is still an important figure, though. Created by the firm of Smith and Tinker in the Land of Ev (who were also responsible for the iron giant with the hammer that guards the Nome Kingdom, and the talking Hundred-Year Alarm Clock possessed by the Wicked Witch Singra), he has three different wind-up mechanisms, one each for thought, speech, and action. He originally belonged to King Evoldo, who locked him in a cave before committing suicide. Dorothy found him there, and brought him to Oz, where he still lives today. Well, except he doesn't really live, because Baum makes a clear distinction between the automated Tik-Tok and created beings who are magically brought to life, like the Scarecrow, the Patchwork Girl, and the Glass Cat. It's not entirely clear how Tik-Tok differs from these other beings, but maybe it has something to do with free will. Tik-Tok does have a certain level of free will and independent thought, but he was constructed to be a servant, and seems to stick to that role. The other three characters I mentioned were also created for servile functions, but all of them walked out on those duties to seek better lives. Also, Tik-Tok doesn't seem to have the same depth of emotion. That said, I'm not sure he's ENTIRELY emotionless, since he does have the occasional independent opinion. Indeed, Ruth Plumly Thompson and John R. Neill show Tik-Tok feeling and expressing enjoyment, but I kind of think they didn't really understand the character as Baum wrote him.
There's an article arguing that Tik-Tok obeyed Isaac Asimov's Three Laws of Robotics long before Asimov thought them up. While interesting, it contains some major stretches, such as the implication that the people of Ev and Oogaboo are not human, but Smith and Tinker somehow are. One fictional universe other than Asimov's own that DOES incorporate the Three Laws, however, is that of the Mega Man games. At the end of Mega Man 7, Dr. Wily reminds the hero that no robot can harm a human being, to which Mega Man replies that he is "more than a robot," but he never gets the chance to do any harm. These laws apparently also apply to Wily's own robots, even though I don't think a villain like him would have any problem with them hurting people. And as far as I can remember, it's true that the fighting in the series is always machine against machine. So, to get stereotypically geeky for a minute, would Mega Man or Tik-Tok win in a fight? I think it would have to be Mega Man, especially with all of his weapon attachments. On the other hand, Rock does seem to be a bit clumsily made, and is immediately destroyed when he hits spikes, which I don't believe would be the case with Tik-Tok. And the Evian robot isn't devoid of fighting skills. He knocks out Wheelers with a dinner pail in Ozma of Oz, handles a gun in Tik-Tok of Oz (although I don't think he ever actually fires it), and is said to be practicing swordplay at the beginning of The Yellow Knight of Oz (maybe he had a new software cartridge installed).
Of course, I can't really write a post about fictional robots without mentioning Futurama's Bender Bending Rodriguez, who would probably beat either Tik-Tok or Mega Man, since he would fight dirty. I'll probably be seeing more of Bender pretty soon, since Bender's Game comes out this week, and I have it at the top of my Netflix queue. Yeah, I know a TRUE Futurama fan would buy a copy, but I'm still holding out hope for a four-pack once these movies are all released.
