Rick Sanchez (Rick and Morty)
He is formally referred to as Rick Sanchez C-137 (alias: "Terror Rick") by the Trans-Dimensional Council of Ricks, in reference to his original universe, "C-137", and penchant for instigating wars with inter-galactic empires. Both Rick and Morty are voiced by Roiland. Volume 1 of the "Rick and Morty" comic series follows the Rick and Morty of Dimension C-132 while most issues of subsequent instalments follow the Rick and Morty of "C-137"; the video game "Pocket Mortys" follows the Rick and Morty of C-123.
Bottle episode
The adult-animated sci-fi sitcom "Rick and Morty" has a bottle episode called "Rixty Minutes". In it, the Smith family alternates between watching the lives of alternate versions of themselves on special goggles and commercials on the TV, the latter being entirely improvised sketches by co-creator Justin Roiland.
