Agent K (also known as K, Kay, and Kevin Brown) is a fictional Men in Black agent in the films Men in Black and Men in Black II and in the Men in Black animated series. Agent K is portrayed by Tommy Lee Jones in the two films and is voiced by Ed O'Ross, and later Gregg Berger in the animated series. Although formally known as Kevin Brown, the film's trading card series notes Agent K's name to be Kevin Cunningham, a nod to Lowell Cunningham, creator of the comic.
