Ben 10, Voice Actors from the world Wikia

Ben 10 (also later known as Ben 10 Classic) is an American animated series created by Man of Action (a group consisting of Duncan Rouleau, Joe Casey, Joe Kelly, and Steven T. Seagle), and produced by Cartoon Network Studios. The series is about a 10-year-old boy named Ben Tennyson who gets a watch-like alien device called the "Omnitrix" (the prefix omni means all). Attached to his wrist, this allows him to transform into various alien creatures. He then uses these powers to fight evil from Earth
