A character inspired by the dark sci-fi world of Blame! (a manga by Tsutomu Nihei).
It's a more slick hard surface version of the proto-organic style of robots from the manga.
In the world of Blame! , this robot is part of a defense system known as the Safeguard. It's designed to kill any humans that no longer carry Net Terminal Genes. What are Net Terminal Genes? Read, the manga! :)
