Cyborg 0013 is an antagonist-turned-hero in the Cyborg 009: The Cyborg Soldier episodes, "Defeat the Invisible Opponent" and "Friend". He is the last model in Black Ghost's 00 line of cyborgs, a pudgy boy who was kidnapped by Black Ghost and linked to a giant robot.
0013 grew up in the same orphanage that 009 grew up in. He was at some point adopted, but in reality he was abducted by Black Ghost to be turned into a cyborg.
0013 first met 009 while out buying bread. However, he was quickly rushed away by his aids.
Later, 0013's robot arrived in Tokyo and rampaged through the city. Monitoring him was Skull and the other top brass of Black Ghost, who used 0013's destruction as a demonstration of Black Ghost's power.
However, 0013 was not without morality, as he refused to kill Dr. Kozumi and even helped 009 save a little girl. 009 was able to convince 0013 to turn good and 0013 killed the Black Ghost assassins going after 009. But, in order to break free of Black Ghost's control, he threw himself off a cliff. While his robot landed in the ocean, his body fell on hard ground. Before he died, he asked for 009's real name. 009 told him that his name was Joe. 0013 died before he could tell 009 his own.
