Carbon Costume

Professor Paradox (voiced by David McCallum) is a time travelling professor on the Cartoon Network show Ben 10.  Professor Paradox forgot his true name long ago and adopted his current moniker after escaping from an alternate reality.  Professor Paradox has two main costumes; a simple modern design with a lab coat, green goggles, brown vest, black tie and slacks, and then a more elaborate look that includes a metal gauntlet, riding boots, and walking stick.  Both designs use the black pants and vest, and you can add accessories to these pieces in order to emulate the version you are interested in replicating.
