Agent L

Agent L (also called Elle, or just L, originally Dr. Laurel Weaver) is an agent of the MiB. She is a beautiful but cynical former deputy medical examiner. She joined MiB after Agent K was neuralyzed, so she became Agent J's new partner but later became chief scientific officer and an assistant to Zed after Agent K came back to be J's partner. In the original film, she was played by Linda Fiorentino. 
== History ==
=== Before MiB ===
In the background, she played a large part before becoming an agent. Laurel Weaver is portrayed as a young and cynical deputy medical examiner. She has a fairly slender figure, and dark hair.
In the first film Laurel investigates the corpse of a man that Officer James Edwards chased. She finds that the man had two different sets of eyelids.
Later on, J, and K search the morgue to look for the bodies of aliens that were killed by Edgar the Bug. After this, she is neuralyzed.
During the middle of the film, she is held captive by Edgar and visited by the agents again. She tries to alert J of the threat with subtle hints but he doesn't catch on until later. Laurel criticizes him for taking too long to get the hint, as he argues back before Edgar stops them. Edgar escapes while abducting Laurel in order to deter pursuit, she attempts to convince him to let her go, implies that Earth will declare war in response due to her being its ruler. However, this only encourages him, since it meant ensuring that he can feed his family's mouths. Laurel compliments his looking out for family and managed to escape. She witnessed Jay and Kay then arrived and shot the ship down.
At the end of the film, she kills the rest of Edgar, after pieces of him tried to kill Kay and Jay while they were unaware, she remarks she is interested in their jobs. Afterwards, she is recruited by the MiB and becomes J's new partner Agent L.
==== Men In Black: The Series ====
In Men in Black The Series she is moved to the lab inside MiB headquarters becoming the chief scientific officer and an assistant to Zed. She also changed her hair from black to blonde.
In The Long Goodbye Syndrome when Jay is pursued by Skraaldian aliens she gives J a freezing weapon to defend himself from them after J accidentally blew one alien up by firing his noisy cricket at him.
In The Big Bad Bug Syndrome, L is pursued by another Bug named Edwin, Edgar's brother who wants revenge on her for Edgar's death. She is kidnapped again but when J and K arrive to rescue her all three are captured. They are later rescued by the Worms and a group of Bug bounty hunters. When the Bug bounty hunters need sugar to survive the Worms give them their sugared coffee. The bounty hunters fire at Edwin killing him just like how Edgar was killed.
In The Musical Chairs Syndrome her role as the chief scientific officer is later replaced by Dr. Zan'dozz Zeeltor because she wanted to move into field work.
She is also given a new partner an alien named Agent X, since J and K were partners again. Since the second film is set before the series, she was de-neuralyzied off-screen for her capabilities shortly before Men in Black 3 (as she couldn't work for Zed after the events of that movie since the latter died). She most likely became an assistant of Agent O after she took the place of Zed after his death.
===== Men In Black II =====
In Men in Black II, set before the series, L does not appear, but is mentioned once. J explains that L apparently wanted to return to medical examiner work.
