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.
Wismichu
In 2008 he began uploading videos to YouTube, initially gameplay videos. Nowadays, his videos often consist of videoblogs, prank videos, and parody videos, mostly infused with an absurdist and dark style of humour, often comparable to [adult swim]'s "Rick and Morty" (which he has referenced multiple times and is indeed a fan of) or the Deadpool comic series.
