Scott Summers (Cable) (Earth-4126)

"I don't know who, or what, I am. I don't know what I was created for. The only thing I do know, is that there is voice in the back of my head telling me to kill.... Scott Summers."

-Cable

HYDRA
When Cable first opened his eyes, he could not remember anything about his past. He was welcomed into the world by the leader of HYDRA, Baron Magnus. Magnus informed Cable that their organization was meant to cleanse the world of human filth, and that he was a mutant. He had the ability to manipulate energy and blast it from his hands, eyes, or anywhere else from his body.

Training
Cable was put through intense, harsh training on Hydra Island. He was constantly insulted by some of the heads such as Quicksilver and Pyro, though he did not know why, and frankly, he didn't care. He knew he didn't want to be doing this. Eventually, he contacted Baron Magnus, requesting permission to leave. When he was denied, he attacked Magnus and broke out, stealing a small, submersible boat, which allowed him to get away.

Civilization
When Cable reached New York, he attempted to hide out in an apartment, but he was continuously drawn to action, trying to start fights with anyone he came into contact with. Eventually that little voice in his head tried to get him to kill someone, and he decided it was time to act.

Silent Guardian
He created a costume and decided to use his true name, Cable, as his hero persona. His first act of heroism was noticed during a battle between the Avengers and their enemies, Code Red. While most of them were down, Taskmater was about to stab Captain America, but Cable shot him through the head, killing him, saving Captain America's life. Cable was caught on camera before disappearing, and was dubbed the "Silent Guardian".
