Serleena is the main antagonist of Men in Black II.
As the evil leader of the Kylothians, Serleena was initially drawn to Earth several years back when the Zarthans attempted to bring the Light of Zartha to Earth under the watch of the MIB agency. Upon entering the scene, Serleena kills a Zarthan leader and dispaired as what she though was the Light of Zartha, flew into orbit. Over the years she travelled from planet to planet in her search for the shuttle, constantly being disappointed and destroying many worlds in bitter anger. However, she was contacted by Scrad & Charlie who notified her that the light had been back on Earth the whole time. After a quick change of course, Serleena headed to Earth, landing in New York. Slipping through the gardens, she finds a magazine showing a Victoria´s Secret model Lara Flynn Boyle in lingerie, working with what she had, she transforms into an exact copy of Boyle.
Almost immediately, a criminal attacks her with a knife. He takes her behind some bushes with the intent of raping her. However, in a twist of events she eats him alive, head first, cramming him tightly into her belly. She begins to digest the thief while walking casually back to the magazine, licking her fingers and moving her belly from left to right to digest him faster. Studying the magazine, she impatiently waits for the thief in her stomach to finish digesting while looking at the picture and tapping her belly with her fingers. Realizing that this ruins her disguise, she returns to the bushes and pukes up his body, then takes his clothes for later use.
She first stops by Scrad/Charlie´s department to find him watching TV and eating junk food. Without him knowing she´s Serleena, Scrad/Charlie gets impressed by her beauty, only to have her shove two tentacles into his ears as a bitter reminder of who he was talking to. They talk about finding the light and agree to look for information at a pizzaria nearby while she eats a greasy hamburger. At the pizzaria, Serleena questions an alien who might know the where-abouts of the Light; getting no usefull information, she slices him with her tentacles. She then storms MIB headquarters, taking everybody captive and releasing the agency's convicts for some assistance. She then sends a handfull of these convicts after Jay as he attempts to restore Kay's memory. After a quck memory restoration and brief brawl, Kay and Jay discover the Light is actually Laura Vasquez, a worker at the pizzeria and daughter of Zarthan Queen Laurana.
Upon returning to headquarters Jay stops the countdown of a machine that would launch Laura into space, and shoots Serleena before she can eat Kay. She is seemingly destroyed, but her initial worm form survives. Quickly, she regenerates and steals a futuristic vehicle to chase after the trio of Jay, Laura, and Kay. After an intense chase scene Serleena is tricked into being eaten by the giant worm, Jeff, along with her spaceship.
To be safe from Serleena's wrath, the trio reach a rooftop and prepare a hidden shuttle for Laura to leave on. However, Jeff bursts through the roof and explodes, revealing Serleena in a giant mutated wormlike form. As Jay was thrown around by her tentacles, trying not to be eaten, Kay casually spoke with Laura before shooting Serleena, releasing Jay. After launching Laura, Serleena returned and showed her true form, that of a huge viney plant, and flew after Laura, but Jay and Kay casually shot her with their weapons, destroying her in a bright fireworks display and returning to HQ.
