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.
Pickle Rick
Zach Blumenfeld of "Paste" calls the episode "arguably the most eagerly anticipated "Rick and Morty episode ever"" due to the large amount of episode content released by Adult Swim before it premiered. Green calls the Pickle Rick concept "season 3's most anticipated wrinkle." In June 2017, "Polygon" published an article entitled "Pickle Rick is already everyone's favorite character from Rick and Morty's third season", citing actions of fans such as creating Twitter and Tumblr accounts for the character. Julia Alexander, the writer of the article, comments that the show has "found a dedicated fan base because of the absurdity it bases its comedy in."
