It's been roughly two years since they were announced, but Disney XD's long-planned Marvel superhero cartoons, Avengers Assemble and Hulk and the Agents of SMASH have finally been given proper release dates, voice casts and new posters showcasing their animated styles.

Avengers Assemble will star Adrian Pasdar (Heroes) as Iron Man, Fred Tatasciore (Ultimate Spider-Man) as the Hulk, Roger Craig Smith (Wreck-It Ralph) as Captain America, Travis Willingham (Shelf Life) as Thor, Troy Baker (Ultimate Spider-Man) as Hawkeye, Laura Bailey (Super Hero Squad) as Black Widow, and Bumper Robinson (The Game) as The Falcon.

While the previous animated iteration of the Avengers, Avengers: Earth's Mightiest Heroes, was critically acclaimed, most fans can agree that it had at least one major flaw: Marvel's Dracula didn't make an appearance. The new version, however, promises appearances by not only everyone's favorite Lord of the Vampires, but also Dr. Doom and the Atlantean Attuma.

Hulk and The Agents of SMASH will see the Green Goliath assembling a team of like-wise hulked-out heroes to take down threats too powerful for other acronym-ed organizations such as SHIELD. The series will star Tatasciore as the voice of the Hulk (matching his role in Avengers Assemble), Eliza Dushku (Dollhouse) as She-Hulk, Clancy Brown (Avengers: Earth's Mightiest Heroes) as Red Hulk, Ben Diskin (Avatar: The Last Airbender) as Skaar, and Seth Green (Robot Chicken) as A-Bomb.

Disney XD has posted a free preview of the 2008 issue of Hulk #3 (written by Jeph Loeb, drawn by Ed McGuinness) on its website, featuring a fight between A-Bomb, Green Hulk and Red Hulk, in a seeming effort to help introduce the characters to new fans.

Avengers Assemble is set to debut on Sunday, July 7 at 11 a.m. EST. Hulk and The Agents of SMASH will premiere Sunday, August 11 at 11 am. EST.
