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.
