Junebug and Johnny are mechanical musicians, motorcyclists, and lovers. They are both androids who used to work as miners until their escape.
In Act III, the duo encounter Conway, Shannon, and Ezra stranded on the highway. Junebug and Johnny fix Conway's truck, and go on to perform "Too Late to Love You," a song originally sung by Lysette, at the Lower Depths tavern.
History
Junebug and Johnny were originally part of a robotic crew manufactured by the Consolidated Power Company to drain Elkhorn Mine after its catastrophic flood. Junebug describes her original build as "about a half-foot shorter, and all gray. No eyes." While in the mine, Johnny discovered one of the archivists' tape decks. Listening to the miner's songs, he and Junebug realized they could be something more, leading them to escape.
Johnny once found a pet frog (or toad, depending on who you ask) in a shoebox on a playground and kept it for about six months.
Appearance
The two ran away in the night and have since been adjusting and detailing themselves to appear more human and more like themselves. Junebug now alters her appearance often, such as by dying her hair blue (and later orange, in Act IV), to reject their previous uniformity and to appear unique and "specific." Junebug consistently boasts a half-shaved hairstyle while Johnny wears dark sunglasses and a flattop. They drive around in their motorcycle with sidecar, which they may choose to name the Weird Vector, the Vicious Cycle, or the Sloth-on-wheels.
Personality
Junebug
Junebug is the de facto leader of the duo, and is more cynical, sassy, and solitary than Johnny. She has a biting sense of black humor – often dark to the point where her jokes are more tragic than funny – with which she habitually teases and flirts with Johnny, who she calls her "cricket." She tends to keep everyone else at an arm's length.
Although she buries it in bitterness and denial, Junebug occasionally lets slip glimpses of an identity crisis between person and machine. She seems concerned about genuineness, and tends to dismiss personal problems. At one point, Junebug may explain that she likes looking at porcelain figurines because of how peculiarly non-genuine she finds them – identical figures with their jobs "painted on" – their definition and value being told through little more than a paint job.
Johnny
Johnny is the more passive of the duo to the extent where he occasionally finds himself compared to a dog, staying behind or at the sidelines with Conway's hound. Despite his assertion that Junebug is the artist – and that he is "only an entertainer" – Johnny appears to be highly creative and poetic. He spends much of his time thinking, daydreaming, composing music, and being distracted by the world around him. He enjoys teasing Junebug, often with her same tragic sense of black humor, and refers to her as "ma'am.
Johnny has a particular affinity for sounds and animals; the duo may explain that he enjoys the digital cacophony of the arcade or the animals at the petting zoo. There are a number of stops along the Zero at which Johnny tries (often unsuccessfully) to record various sounds with his tape recorder. He calls Junebug "ma'am."

Inspiration
References to Loretta Lynn
Junebug was originally based on Loretta Lynn, a country singer-songwriter known for her song "Coal Miner's Daughter." Although her final design contains significant changes, Junebug's extravagant blue gown remains a reference to Lynn.
References to the transgender experience
Many of Junebug's experiences mirror those of transgender individuals. She was originally built with a different body and role in mind, and as a result has had to build her identity from the ground up. Additionally, Junebug's complaints about "authenticity" may be a metaphor for her own dysphoria.
