Nathan Summers is the biological son of the X-Men member Cyclops (Scott Summers) and his first wife Madelyne Pryor (Jean Grey's clone). This makes him the "half"-brother of Rachel Summers (a child of Scott and Jean from an alternate timeline who later comes to the mainstream Marvel timeline) and Nate Grey (a clone created from the combined DNA of Scott and Jean). The mutant terrorist Stryfe is a clone of Cable and one of his deadliest enemies. Born in the present-day, Nathan was infected with a deadly techno-organic virus while still an infant. He was sent into a possible future timeline where he could be treated and live his life. In this future world, Nathan grew into the warrior Cable and became an enemy of the villain Apocalypse. He later returned to the present-day era, initially arriving some years before his own birth. Since making his home in the modern era, he has worked alongside the X-Men (including Cyclops and Jean Grey) and reformed the New Mutants group into the original X-Force. He had frequent battles against the near-invincible assassin Deadpool, who later became an on-again, off-again ally for years. In the 2018 Extermination mini-series, Cable was killed and replaced by a younger, time-displaced version of himself who decided that the older one didn't do a good enough job. This younger Cable (sometimes called Kid Cable) is still operating today.
