I've always had this idea for a great X-Men story, and it goes something like this:
The X-Men are doing their usual thing--hanging around and waiting for someone to attack them--and all of a sudden Apocalypse drops out of the sky. He does his usual stuff about how he will make rivers run red with blood and the sun will darken with the ashes of burnt bodies and he will sit on a throne of skulls and only the strong will survive. . .
And as he's doing this, the X-Men walk away, disgusted. Heard it so many times and so many ways, and they're just tired of it. Every panel is people's feet walking away in the foreground as Apocalypse gets smaller and smaller in the background.
And all the while, Apocalypse is still doing his usual tired spiel, only with added desperation now. "Come on! Throne of skulls! Rivers of blood! Survival of the fittest! C'mon guys!"
And that's the last we ever see of Apocalypse.
