In a presentation to advertising executives in New York, The Cartoon Network announced it will air more than 500 new half-hours, including five new animated series this year. The new shows are:

Megas XLR – A new action-comedy series about a 20-something grease monkey who discovers a giant fighting robot from the future in a New Jersey landfill. Premieres on Saturday, May 1, at 9 p.m.

Foster’s Home for Imaginary Friends – From Craig McCracken, creator of The Powerpuff Girls, Foster’s Home for Imaginary Friends premieres with a 90-minute feature on Friday, July 16, followed by the series premiere on Friday, September 3.

Justice League Unlimited – The heroes of the Justice League return in August with a new series, Justice League Unlimited, which incorporates a bold new look and a much larger scope.

Atomic Betty – This new series, set to premiere in September, follows the adventures of Betty, a little girl with a secret superhero identity.

Hi Hi Puffy AmiYumi – One of Japan’s biggest pop music acts arrives in America, not with a massive stadium tour but as a cartoon. Hi Hi Puffy AmiYumi, set to debut in December, follows the adventures of two very cool, but very different, pop stars as they travel from gig to gig or just hang out in their hometown of Tokyo.

The Life and Times of Juniper Lee – Juniper Lee is a typical 11-year-old girl born into the secret responsibility of fighting the forces of mischief and chaos that hide everywhere. On any given day, she may have to skip out on her best friend’s birthday party to discipline some unruly 6-foot leprechauns or smack down some troublemaking gnomes. The Life and Times of Juniper Lee, from creator Judd Winnick, will premiere in February 2005.
