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.
Invader Zim
Variety’s Steven Oxman, wrote, “[Invader Zim] captures a nice blend of the innocent and the satirical”. Further stating that, “The artwork [in the show] isn’t especially original but still manages to create a nicely off-center vision of Earth and its inhabitants. Vasquez and co-writer Rob Hummel throw in some clever quips at life on this planet, taking aim particularly at the doomsaying schoolteacher, Ms. Bitters. Kevin Manthei’s music provides strong accompaniment to the escapades.” Ryan Carlquist, from Screen Rant said, “Invader Zim is without a doubt one of the strangest and chillingly creepy television programs to debut on Nickelodeon. Following in the trippy cartoon styles of The Ren & Stimpy Show before it, Invader Zim doubled down on its oddball off-brand humor and its silly and often-times haunting characters. Invader Zim now appears to be a product that just happened to arrive far too soon. Rick and Morty has proven that audiences will flock in droves to be unnerved and made uncomfortable by a show that propels forward thanks to its “off the rails” narrative. The lack of a real coherent structure is something that's often lauded in television today, but was virtually unheard of in cartoons back when Invader Zim premiered.”
