WMG / Cyborg 009

Cyborg 002 is the father of Brendon Small

The reincarnated 003 is pregnant with 001 at the end of God's War

The ending states that even though 001 isn't present in the group shot, he's still there. Joe and Francoise are married in this new world and Ivan will be reincarnated as their son, since Francoise served as a substitute mother to him during the series proper.

Cyborg 009 is a Speed Force user

Think about it. It all fits. The Superspeed, the molecule acceleration in the God's War OVA's, the red and yellow theme? Cyborg 009 is either now, or will someday become The Flash of his world.

Cyborg 004 was fighting his Tethered counterpart

Albert Heinrich's doppelganger in "Man or Machine" was actually his Tethered clone, who had received cybernetic augmentation to mirror his upper world counterpart. Much like the other Tethered, Albert's clone was incapable of speech and driven by an implacable desire to murder his counterpart.

Cyborg 008's original appearance was deliberately altered to look more stereotypical by Black Ghost.

BG felt that he'd more effective as a worldwide agent of terror if he looked particularly strange to seafaring cultures including other Africans. They altered his facial bone structure in such a way that it would have been too dangerous to revert him back to normal, until 008 began began developing severe anxiety attacks and depression regarding his appearance. For the sake of 008's mental health Dr. Gilmore was forced to perform the surgery, leading to his more normal appearances in later incarnations of the show.
