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.
Rick Sanchez (Rick and Morty)
Rick has been stated to be pansexual by Justin Roiland, one of the show's creators and executive producers. This was shown in "Auto Erotic Assimilation", when Rick connects with Unity, an ex-lover who is a collective hive mind of assimilated individuals from the planet they occupy. Throughout the series, Rick's sexuality has also been heavily hinted at, mostly in his backstory.
