10. Smallville (Almost)
Main Character Missing: Clark Kent (1 Episode, almost).
Which Episode?: "Gemini" (Season 7, Episode 9).
Is It Still Good?: Yes Okay, this one is cheating a little. It bends so many rules it could earn a spot in the X-Men film series continuity. The plot is basically your run of the mill Smallville Season 7 episode. It plods along like there's no missing Clark, and that's because, in all technicality, there isn't. This is another reason why this particular entry is probably cheating, as the actor who plays Superman, Tom Welling, is actually playing Bizarro disguising himself as the Man Of Steel throughout the whole episode. So the actor is entirely present, but what about the character? Well, he has about six seconds of screen time at the very end of the episode, frozen in the Fortress Of Solitude. In addition to this, it's also a kind-hearted Christmas venture, worthy of a watch.
