Ratton is best known as the creator of Hymie the robot [Episode #19: "Back to the Old Drawing Board"]. Initially employed by KAOS, Hymie eventually joins CONTROL instead. Convinced that it is Hymie that gives CONTROL its advantage, KAOS calls upon Dr. Ratton to create an even more powerful robot to destroy him. The result is Groppo. In a short-sighted move, before sending Groppo after Hymie, KAOS agent Spinoza orders him to destroy Dr. Ratton, to ensure that KAOS will be the only organization with "the ultimate weapon" [Episode #68: "When Good Fellows Get Together"]. Portrayed by Jim Boles.
