The President of the United States

From Ben10versepedia

The President of the United States appeared in "The Unnaturals", where "the Squires" and the Forever Knights tried to replace him with a robot. When Ben as Fourarms defeated the Squires Coach robot and the Omnitrix timed out, the robot coach was about to attack the President but Ben saved him and destroyed the robot for good. The President mistakes Ben for Cash, one of the bullies that picks on him, for saving his life because Ben took Cash's place in the last game. It should be noted that this is a fictional president, and not a caricature of the current one actually in office.
