The Beatbox Alien (also called the Rapping Alien) is an unique alien shown in Men in Black II. Here, Jay convinces Kay (working at a post office in Massachusetts post-neuralyzation) that aliens are real. He then exposes that nearly everyone in the post office is an alien. Jay uses a translator to talk to the alien. They talk to each other in beatbox. The Beatbox Alien was portrayed by rapper Biz Markie.
- The second beat Jay does to communicate with the Beatbox Alien is from the end of the song "La Di Da Di" by Slick Rick.
