Agent K (usually called Kay), born Kevin Cunningham Brown, is a fictional character and one of the two main protagonists of the Men in Black franchise (the other being Agent J). Kay is portrayed by Tommy Lee Jones in the three films, with Josh Brolin portraying his younger self in the third film, and voiced by Ed O'Ross and Gregg Berger in the animated series. The film's trading card series and Men in Black: The Game give K's full name as Kevin Cunningham, a nod to Lowell Cunningham, the creator of the comic.
