Casshern Sins (キャシャーン Sins) is a reboot of the classic anime series Casshan, produced by Tatsunoko and animated by Madhouse. The series completely discards the continuity presented in the original Casshan anime series, in which Casshern was a cybernetic superhero battling the evil robotic forces of Braiking Boss in a post-apocalyptic Earth. In Casshern Sins, Casshern is presented as a cyborg subordinate of Braiking Boss who was ordered to assassinate the savior of mankind, and has thus doomed the Earth to ruin. Casshern Sins made its English broadcast premiere on Funimation Channel on December 14, 2010. A manga adaptation was published in Jive's Monthly Comic Rush Magazine. In the United States, the series began airing on Adult Swim's Toonami block as part of its premiere on May 26, 2012.
