Brian Michael Bendis-penned, animated comic-thing, Chronicles of Doom, but Dr. Doom is sort of a jerk. That's primarily why you'll spend most of your time in the now-live Marvel Heroes working to deliver him a swift punch in the metal jaw.
The final episode follows Dr. Doom as his plan to seize the Cosmic Cube comes to fruition and as he broods dramatically and monologues about an invincible army in the way super-villains generally do. There's also a mysterious figure watching Doom from beyond -- presumably pondering a method for intervening in his dastardly plans.
Check it out after the jump. And if you missed episode three, well, we've thrown that one in for you as well.
