Although Victor Stone was a noteworthy example of a Cyborg, such life forms were rare during the twentieth century. In fact, when Superman met Cybron in 1988, he had assumed that with the exception of Cyborg, such technology was still around a thousand years away from being invented.
- ↑ As seen in the Superfriends season 9 episode The Bizarro Super Powers Team (1985).
- ↑ As seen in the Superfriends season 9 episode The Seeds of Doom (1985).
- ↑ As seen in the Superman episode Cybron Strikes (1988). It should be noted however, that Cyborg wasn't actually mentioned in that episode, but still, he would have known him for three years at that point which is why it's being mentioned here. He obviously was referring to the existence of Cybernetic Organisms in the general sense, which with the exception of Victor Stone, didn't actually exist at that time.
