Cable Existence

(Nathan Summers) is a fictional character appearing in American comic books published by Marvel Comics, commonly in association with X-Force and the X-Men. The character first appeared as a newborn infant in Uncanny X-Men #201 (Jan. 1986) created by writer Chris Claremont, while Cable's adult identity was created by writer Louise Simonson and artist/co-writer Rob Liefeld, and first appeared in The New Mutants #87 (March 1990).
Nathan Summers is the biological son of the X-Men member Cyclops (Scott Summers) and Madelyne Pryor (Jean Grey's clone), the "half" brother of Rachel Summers and Nate Grey, and the genetic template for Stryfe. He is from a possible future timeline, having been transported as an infant to the future, where he grew into a warrior, before returning to the present.
Josh Brolin will portray Cable in the X-Men film series, beginning with Deadpool 2. Nathan Christopher Charles Summers is the son of Scott Summers (aka Cyclops), and Madeline Pryor (who was later revealed to be a clone of Jean Grey). Writer Chris Claremont, who had written the series since issue #94 (August 1975), revealed Madeline to be pregnant in X-Men/Alpha Flight #1 (December 1985).[2] The next depiction of her pregnancy was in The Uncanny X-Men #200, when she goes into premature labor.[3] In the following issue, #201 (January 1986), Nathan first appears as a newborn infant.
