Agent J (born James Darrell Edwards III, and also called Jay, or just J) is a fictional MIB agent in the film Men in Black, its sequels Men in Black II and Men in Black 3, and Men in Black: The Series. Jay is portrayed by Will Smith in the three films and voiced by Keith Diamond in the animated series.
Not much is known of the life of James Darrell Edwards III prior to being recruited to MIB. His appearance as a small child in 1969 in Men in Black 3 would place his year of birth in 1965 (yet in real life, Will Smith was born in 1968). His father, United States Army Colonel James Darrell Edwards II, was working security at Kennedy Space Center for the Apollo 11 launch when he was murdered by Boris the Animal after assisting Agent K in stopping a chain of events that would have led to K's death and a widescale invasion of Earth forty years later. Although young James was present at the event, K uses the neuralyzer on the young boy, saying his father was a hero. James was left with his father's pocket watch to remember him by. Nothing else is known about the preceding twenty-eight years save that James became an accomplished police officer with the New York City Police Department. It does not appear as if he had any family by the mid-1990s.
Though little is known of J's personal life outside of his role as an agent of Men in Black, he is known to be a big fan of both video games, which he is seen playing in his off hours, and rap music. A line of dialogue from Men in Black II suggests his mother once bought him a Game Boy.
Agent J's MIB career starts out when, as NYPD officer James Edwards, he runs down a swift, wall-climbing alien on foot. When MIB Agent K notices his potential, he recruits him into the MIB (it should be noted that within the continuity of the series, the events of Men in Black 3 would imply that K recognized J from their meeting in the 60s). At first, Edwards is suspicious, but he decides to join. He is registered as Agent J and his energetic, enthusiastic attitude brings humor to a bland organization. J is not fond of K's diminutive references to him (son, sport, slick, kid, etc.), but gets used to it. In his various adventures, he encounters Frank, the dog; finds out that Jeebs, the pawn store owner is actually an alien, not just a buyer of stolen goods from chain snatchers like he originally thought when he was a detective; and delivers a baby squid. Their first official mission is to stop an alien Bug from leaving Earth with a tiny galaxy before the galaxy's owners disintegrate the planet. During the final confrontation with the bug, K is swallowed by it in an attempt to get his gun back, leaving J to keep him on Earth. When he starts squishing cockroaches, the Bug confronts him, but before it can attack him, K shoots it from the inside. The Bug was finally killed by Dr. Laurel Weaver (Linda Fiorentino), a morgue worker. When K requests to be neuralyzed (a memory-wiping procedure) to retire, J fulfills the request and his new partner is Laurel, who becomes known as Agent L.
Agent J stays as the partner of Agent K as the events right after the destruction of the Bug by Agent L never occur. Not only he remains the partner of Agent K but also is still considered a rookie by most of the MIBs, including Agent K, L and Z. He is rarely allowed to drive an official MIB Car, many secrets are kept from him, they don't let him handle certain equipment, among other things. 
At some point between the first and second film, L goes back to her morgue career, and J has gained a reputation for neuralyzing all of her successors for, in his opinion, unsuitability to work at MIB; at the beginning of the film, he neuralyzes his new partner Agent T because he forces T to admit that he joined the agency to be a hero, something that is fundamentally impossible in the Men in Black due to the secretive nature of the organization. Other than that, he has developed into a superb and highly respected agent. When he is sent to get K back to face a new threat to which only he had details of locked away in his mind, J's temporary partner is an alien disguised as a talkative pug, Frank. J investigates a murder at a local pizza joint committed by Serleena, the Kylothian queen who has arrived to find the Light of Zartha after destroying several planets. During the investigation, he meets and falls in love with an employee named Laura Vasquez. Despite the MIB's policy, J does not neuralyze her. J then heads to find Kevin Brown who holds the key to finding the Light of Zartha and stopping Serleena before she could get her hands on the Light. When K is de-neuralyzed, J is once again the rookie, but for revenge, J gives K the Noisy Cricket (the tiny gun that K saddled him with in the first movie, though it does have a strong blast). The duo discover the light is Laura, and J (reluctantly) allows her to fulfill her destiny as he and K finally destroy Serleena for good.
During the film, J has a particular enmity with the alien criminal known as Jara, whom J stopped from stealing the Earth's ozone layer.
In the third film J has become a well-respected, Rank A MIB agent in the year 2012. The escaped alien criminal Boris the Animal time-travels back to 1969 and murders a young K, which could result in the end of the world as K was no longer present to establish a force-field that could permanently protect Earth from invasion by Boris's species. Thanks to "being there" when the major moment in history changed (the installation of the ArcNet), J was able to retain all memory of K. J travels back to 1969 to save his partner although hampered by his lack of knowledge of K's personal life or the specific details of the case that killed him. To keep the present unchanged by Boris's interference, J advises K to kill the Boglodite instead of arresting him as in the original timeline. Despite the odds, J and the young K are able to activate the ArcNet force field around Earth and defeat the Borises with the older one getting burned to death by Apollo 11's exhaust; K kills the younger Boris after witnessing him killing a colonel, who is later revealed to be J's father. J also witnessed the young K neuralyzing the young J and then telling the young James that his father was a hero. Following his return to the present timeline, J, now knowing of his father's last moments, comes by to the old K and thanks him for watching his back, to which K responds that it was a 'privilege.'
