Revolio Clockberg Jr.
Alien gearperson, party guest, and amateur musician first appearing in the "Ricksy Business" episode (April 14, 2014) of animated sci-fi spoof series Rick and Morty. He is also referred to as "Gearhead," but later reveals this is a racial epithet to his people.
He is an amateur historian of the Gear Wars of his people, and will go on and on about, even singing a song about it.
Clockberg's guitar appears to be based on Adam's guitar from "The Way to Eden" episode of Star Trek.
