Universes collide on this week's episode of Ultimate Spider-Man, as Peter Parker is joined but an angry but lovable Hulk. Check out the promo for tomorrow's new episode of USM.

With Disney XD's Marvel Universe programming block debuting on April 1, USA Today has this clip of the new feature 'Master Class', in which viewers get a look at how to create the Marvels. In this sneak peek, Joe Quesada gives a tutorial on how to draw the Hulk, along with a history lesson on when and why the change was made from grey to green.

As we've already seen in some promotional stills, the Kree will be making their presence known in the upcoming second season of Avengers: Earth's Mightiest Heroes. Here's a look at what to expect when the show returns to Disney XD on April 1.

This sounds interesting. A new feature to be introduced in the upcoming Marvel Universe programming block, Marvel Mash-ups, to combine classic animated Marvel shows with new voiceovers and other twists. Triple rainbow Doctor Doom? Yes, please!

Says Cort Lane, Vice President, Animation Development & Production,

“We just went at it, taking sections, re-editing them, trying to do dialogue with them, and we got in the booth with some amazing voice actors such as Tom Kenney, the voice of SpongeBob Squarepants and Doctor Octopus on ‘Ultimate Spider-Man.’ We even encouraged the voice talent to riff off of our script.”

“We’re doing eight of them, and they are focused on introducing kids to characters they’ll see in Marvel Universe block and want to know more about,” Lane divulges. “I can tell you that we’re doing them for Iron Man, Iron Fist, White Tiger, and even villains like Doctor Octopus.

Marvel has released this new promo for the upcoming animated series Ultimate Spider-Man, which along with season 2 of Avengers: Earth's Mightiest Heroes will anchor the Marvel Universe programming block on Disney XD beginning April 1. Like the recently released clips from the premiere episode, this trailer combines Spectacular Spider-Man type action with comedy and art style reminiscent of Cartoon Network's Teen Titans.
