In the TV sitcom 'Seinfeld', what is the name of Jerry's nemesis, played by Wayne Knight?

Newman is a recurring character and arch-nemesis of Jerry Seinfeld on the television show 'Seinfeld'. Portrayed by Wayne Knight from 1992 until the show's finale in 1998, Newman was ranked 16th on 'The Rolling Stones' list of '40 Greatest TV Villains of All Time'.

'Seinfeld' is an American sitcom created by Jerry Seinfeld, who also plays the main character of the same name. The show is about four friends in New York City living their day-to-day lives. Jerry is a comedian who always gets himself into strange situations. His friend George Costanza (played by Jason Alexander) is a neurotic estate agent, who is convinced nobody likes him. The third friend in the group is Elaine Bennes (played by Julia Louis-Dreyfus), Jerry's ex-girlfriend, and the fourth is Cosmo Kramer (played by Michael Richards), Jerry's very tall neighbour.

Newman is a lazy mailman who works for the United States Postal Service. Whilst he is a friend of Kramer, he and Jerry never see eye-to-eye. Despite the show beginning in 1989, Newman did not physically appear until 1992, although his voice had been heard several times off-screen in previous episodes.

Throughout the series, Newman often schemes against Jerry, who he thinks is not deserving of his fame as a comedian. Jerry frequently refers to Newman as "pure evil", but when asked why the character hated Newman so much, the actor responded, "it just seemed funny to hate Newman."
