Man of Action Studios is a group of comic book creators featuring Duncan Rouleau (writer), Joe Casey (writer and artist), Joe Kelly (writer and artist) and Steven T. Seagle (writer and artist). They are famous for creating ''WesternAnimation/{{Ben 10}}'' and ''WesternAnimation/GeneratorRex'' for Creator/CartoonNetwork.

Man of Action got its start when writers Steven Seagle and Joe Kelly stood in front of the panel platform at the San Diego Comic Con, while Joe Casey leaned casually at the end, and artist Duncan Rouleau parked himself behind the lectern. The four friends recalled how they created Man of Action many years ago in response to "wanting a place to sit down at the San Diego Comic Con". They grew tired of wandering around the large convention and decided they needed a booth. In order to have a booth, they needed a company.

During the time they worked on Cartoon Network, the team was fairly popular for creating two rather well-received shows, including [[{{Ben10}} one]] that became iconic of the channel and got three sequels (though they were only directly involved with the Original Show, they did contribute to some of the sequel, such as writing the Crossover Ben10GeneratorRexHeroesUnited). However, they have since then started working for Marvel Animation, where they gathered some haters in the comic book fanbase due to their Marvel series (especially WesternAnimation/UltimateSpiderMan) being rather... [[LoveItOrHateIt controversial]].
