Arnie Kowalski (Lou Hirsch) is George's American cousin and confidant. Originally a superhero himself named Polarman, he lost his powers because he began charging for his services. He is portrayed as being greedy, willing to do anything to make money, regardless of who it harms, including himself. In one episode, he gets his powers back from the Ultron Council, and becomes the new hero in town, in order to allow George to have a break from his duties and to spend more time with Janet. However, he soon has them taken away again when he is caught stealing from those he saved, including stealing the Crown Jewels from the Queen.
