Apollo or Apollon may refer to the leader of the Greek mythology-themed cyborgs, appearing in the Mythos arc and adaptations that source the story. His incarnations are listed below, and differ in some regards.

Depending on the incarnation, he is either the younger brother of a cyborg known as Helena or Artemis, or his connection to them is unstated (as with the Mega-CD game).
