Davey Johnson was born and raised in Grand Island, Nebraska, birthplace of Dick Cavett and Henry Fonda. At the age of nine, he was run over by a van, broke his leg, and spent a month and a half in the hospital, where he decided to stop pursuing sports and start a relationship with the stage. In 2002, Davey graduated from Nebraska Wesleyan University with a BFA in Theater Performance and a minor in Japanese. Soon after, Davey moved to Los Angeles, California, where he has established himself as a frequent performer at alternative comedy venues (such as the Upright Citizens Brigade Theatre, the Steve Allen Theater, and the Comedy Central Stage) and as a commercial actor. On Adventure Time, Davey voices Xergiok in "The Silent King," "The Great Bird Man," and "All the Little People," as well as the title character named after him in the season five episode, "Davey."
