Texhnolyze (テクノライズ, Tekunoraizu) are the artificial limbs to be attached to a human body.
Texhnolyzation is the process of replacing organic limbs with highly advanced prosthetics. Eriko Kamata (Doc) thought that texhnolyzation was the very means for mankind to evolve into the next species.
The texhnolyze technology applied to humans, mainly in Ichise and Onishi's case but also Kano. Later events take this trope to a very disturbing extreme with the Shapes, humans who discard their biological bodies to be almost fully automatized as mechanical beings.
