1. Ultron

(The Avengers, Marvel Comics)

Who else is this much fun to talk about?

Ultron is one of the greatest visual designs I've ever seen for a supervillain. He was a prototypical evil robot, and one of the best robots in all of comics. Ultron was an artificial intelligence created by Hank Pym. His original body looked like a moderately evil vacuum cleaner. But that evil Hoover had plans.

That haunting face burns itself into your brain. Like a robot jack o'lantern. But spookier. When you see that wide smile flowing with Kirby Crackle coming at you out of the darkness, you wonder if maybe this time he really is going to take over the world. Ultron is also scary for his habit of constantly re-building himself to be bigger and better. He's almost at the singularity. And we should all fear his terrifying wrath.

When I close my eyes and picture a comic book robot, Ultron's grin immediately comes to mind.

And there you have it. Ten wonderful machines for your reading pleasure. Good, evil, neutral, all manner of Artificial Americans. I, for one, welcome our new robot overlords. Can't do much worse a job.
