Exclusive: Marvel's Super Hero Squad Enlists A-List Guest Stars

The Super Hero Squad Show, Cartoon Network's adorable kid-friendly series starring Marvel Comics icons, boldly goes on a casting spree for its upcoming second season, which will be previewed next week Comic-Con.

"We explore what happens in the Marvel Universe outside of Earth — different dimensions, outer space and all these crazy places," says Cort Lane, Marvel's VP for animation. "So we took the opportunity to feature guest stars to explore those more sci-fi characters." Cameos will come from a hall of fame of the genre, as well as some prime-time comedy stars, to emphasize the show's humorous tone.

On the roster are (pictured, clockwise from top): Star Trek's George Takei, returning as Galactus, Ty Burrell (Modern Family) as Captain Marvel, Jim Parsons (The Big Bang Theory) as Nightmare, Jane Lynch (Glee) as Nebula, Katee Sackhoff (Battlestar Galactica) as She-Hulk and Adam West (Batman) as Nighthawk.

Also coming this season are Mark Hamill (Star Wars), Jonathan Frakes and Michael Dorn (Star Trek: The Next Generation), John Barrowman (Torchwood), James Marsters (Buffy the Vampire Slayer), Kevin Sorbo (Hercules) and Nina Dobrev (The Vampire Diaries). "Honestly, it's shocking," Lane jokes, "because we're only paying scale."
