Technomimicry – The ability to become a machine and/or turn organic beings into machines. The ability of an organic being to merge with a robot. The ability of a robot to possess humans and effectively make them into robot servitors. A cyborg is part machine and part human. Technomimicry goes beyond cyborgization and is the transformation of the human into a robot or robot servitor.
Also, the ability to turn a robot into a human although this is much less common than turning a human into a robot.
The Maschinenmensch of the film Metropolis (1927) is the archetype of this sort of a character.
A video is worth a thousand pictures!
