I watched a Sci-fi show, where there was a robot/android black with I believe was a 8 on its chest and when he fights he runs back and forth past its target cutting it with its sharp hands. He had a human face and I believe he had a body fashioned like casshern with the same type of action like face piece. When he runs his feet hit the ground like metal intermentingly scraping across rail road tracks.
