Unleash your evil side with our Child Generator Rex Van Kleiss Costume. This officially licensed cartoon outfit includes a coat with attached shirt, inflatable arm weapon, and character mask. This antagonist wears a long brown coat over his ensemble. His mechanical chest piece is printed on the shirt to recreate his nanite technology on your clothes. Van Kleiss' goal is to create a world inhabited entirely by EVOs. You can add some spunk to your Van Kleiss uniform with accessories from the TV show like gloves, boots, and other weapons. You can also get your friends to dress as other characters from the cartoon and form a dress-up group. Have a blast trick-or-treating or simply watching the show in style with our boy's Van Kleiss Generator Rex costume.
