Many fans of One-Punch Man will recognize the monster-hunting hero Genos. His early appearance in the series has produced many gags, especially at the expense of Saitama as his self-proclaimed apprentice. His past is full of tragedy and mystery, with an arc that has yet to play out in full detail. One thing that is clear is that Genos is an advanced cyborg, which has led to his infamous hero name Demon Cyborg. But, just how much of Genos is cybernetic? Is there anything human left in Genos or is he a walking, talking, killing machine?
