-Golden Boy to John Constantine
John Constantine's twin brother, who in this dimension was strangled by John's umbilicle cord in the womb. But in another dimension he was the one who lived. He was also named John and grew to be everything his twin brother wasn't; a powerful, well-adjusted, and well-loved, magician.
The Golden Boy and John saw image of one another and the Golden Boy was afraid of his twin and attempted to kill John. This set off a reaction, which eventually led to the combining of their souls.
