Cable
From: Marvel Comics
Nathan Summers is the son of “Cyclops” Scott Summers and Jean Grey clone, Madelyne Pryor. Mister Sinister manages to get Nathan away from them, but before he can fully infect Nathan with a techno-organic virus, he is saved. Of course, it is still in his system but in the future…he can be treated. Thus, they’d head to the future to ensure Nathan survived. Eventually, the techno virus is stopped but it still affected him some. That only led to some extra mutant powers due to the cybernetic enhancements the virus offered, such as enhanced strength and speed along with being able to interface with any technology. Of course, he also has telekinesis and telepathy. All of this led him to become a notable warrior, known as Cable.
He became a major enemy to Apocalypse in this future world but decided to go back in time a few years before his own birth. This is a time in which his parents aren’t who they once were. Cyclops is with Jean Grey, not her clone at this time. Thus, making interactions with Cable pretty awkward. Cable puts the X-Force together with a lot of newer mutants to take on present-day threats in this newer era. It is clear that Cable’s line is pretty much invisible. If he feels a life needs to end, even that of a child, he will end it if he believes it will ensure the safety of mankind. There are very few comic book antiheroes this cold and unwavering, making Cable one of the best in our eyes.
