The first season, titled Gēmusetto Machu Picchu (stylized as ゲ–ムセット Machu Picchu), follows the exploits of Makasu, a sportsman and relic thief, who constantly challenges the gods of several different religions for their relics, and his companion Back Pocket Dimension Flying Bear, on their quest to gain the treasures of the Inca-gods all the while he is chased by Bendy Rivers, a member of Interpol tasked with stopping Makasu.
The first season parodies anime-style shows, intentionally using rather strange and amateurish animation, constantly shifting quality in drawing-style, as well as rather off-beat and crass humor.
The series' debut was also simulcast on the Canadian cable network Action,[2] which was already scheduled to become an Adult Swim-branded channel later that morning at 6:00 a.m.[3] The second season was initially announced on April 1, 2020, with the cold open and intro to episode 1 airing as the start of Adult Swim's April Fools prank.
The intro, however, would be interrupted by Post Malone, leading into the actual prank for the night, three-and-a-half hours of sneak peeks.
Creator Max Simonet originally confirmed a September 25, 2020 release date on the Adult Swim Podcast.
