The TV show Ben 10 was created by the company  Man of Action Entertainment. Ben 10 was produced by Cartoon Network Studios. Man of Action is a group of comic book creators Duncan Rouleau, Joe Casey, Joe Kelly, and Steven T. Seagle. The group worked on the Ben 10 concept for nearly 3 years before  Cartoon Network picked up the series . Dave Johnson also helped in the design development. Early on  in development, it was decided that a villain would be within the Omnitrix. After Ghostfreak was created the creators added dialog into the first season to give the audience that there is something more to ghostfreak. Originally Cannonbolt, the 11th alien transformation in the series was going to be in the original set of aliens but was replaced by ghostfreak. When doing test animations for the series, the first alien to be tested was four arms. It was the most popular transformation out of all the aliens for Man of Action. Many of the unused designs for Upchuck were recycled in the episode ben 10,000 as to of Ben’s aliens “Spitter” and “Articguana”, and as a villain Sploot. Steven E Gordon worked  on an early version of the show, and some of his concept work reveals that Ben Tennyson was originally going to be a redhead young boy. Gordon also has early design of the Omnitrix which look more like a watch the the final version, as well as different designs and names for the alien transformation. Some of the early names for the transformation were 

“StrongGuy”,“Inferno”,”RazorJaw”,”Dragonfly”,”Plantguy”, and “Digger”. 

Some of the early designs for the aliens were more human design, and superheroic.
The series centers around Ben Tennyson (Played by Tara Strong), a ten year old on a cross-country summer vacation, with his cousin Gwen and their grandfather Max. On their first night camping in there grandfather’s RV affectionately named the Rustbucket, Ben finds an alien pod with a mysterious watch-like device named the Omnitrix. The device permanently attaches itself to his wrist  giving him the ability to transform into variety of alien life-forms each with their own powers. WIth his newfound superpowers, Ben has to learn the responsibilities of being a hero. During their vacation, the Tennyson are attacked by various enemies ranging from space aliens to supernatural beings. The theme song for the series was written by Andy Sturmer and sung by Ms. Moxy. The main title was created by Renegade Animation, who was well kown for Hi Hi puffy Amiyumi, which was created by Ben 10’s executive producer Sam Register. The flash animated sequence during the main title was designed to let the audience know that the show is going to be fun and not just an action show.  The opening credits were altered in the third season and beyond to reflect that ghostfreak was no longer to be used, and was replaced by Cannonbolt as the ninth alien. Steven Blum voices Ben’s alien transformations Heatblast and Ghostfreak, as well as the series’ main villain Vilgax.
