The most important and simultaneously ambiguous theoretical concepts in the analysis of techno-body, which is regarded as dis-embodied figure in posthumanism, are ‘corporeality’, ‘gender identity’, and the dimension of ‘post-gender’ in the theoretical reflection on techno-body from the techno-feminist perspective. I analyze the different processes of dis-embodiment and re-embodiment in the comparing of Maria in the movie <Metropolis> and Ava in the movie <Ex Machina>. It is necessary to redefine the concept of corporeality of techno-body as hybrid form of ‘human’ and ‘machine’ in the theoretical application of techno-feminism. Corporeality of techno-body has no more the meaning of organic body, but the meaning of the floating body according to the programming process of techno-body. The dis-embodiment of ‘Maschinen-Mensch’ Maria in the movie <Metropolis> and re-embodiment of human body of A.I. robot Ava in the movie <Ex Machina> confirm that the hybrid subject between human and machine establishes in a techno-body as a robot. In this context the hybrid subject can be considered as the main theoretical point of techno-feminism.
