My name is Jor El I was one of the top scientists on my planet a world known as Krypton. We were an advanced civilization albeit a flawed one like so many others. During the final days of my planet I only had time to build a ship for my one and only son Kal El.
The last thing my wife and I saw as the world burned was Kal El flying off toward his new home. When his ship arrived he was found by a couple who raised him as their own son I owe them more than I can possibly say for that. They lived happily for many years as a normal family regrettably however their happiness was short lived an organization known as S.H.I.E.L.D. learned of my son's existence they made attempts to take him from the Kent Family but were turned down at every attempt.
That was when Hydra an organization not so different from S.H.I.E.L.D. entered they took my son by force killed the couple who welcomed my son as one of their own as well as any S.H.I.E.L.D. agent not secretly aligned with Hydra. Knowing my son's potential Hydra did whatever they could to break from standard brain washing tactics to forcing him to comply.
None of it worked of course until finally a man by the name of John Garrett came up with a plan. The idea was to take the memories of an ideal Hydra recruit and place them inside my son and when his powers emerged make him the perfect weapon for Hydra.
As you might have surmised nothing went as they planned when Garrett died the project died with him and now that my son was freed from their control his powers had begun to awaken it took time as you might suspect somewhere over a year and as his powers awakened so did his memories his real memories.
Eventually my son made it to the Fortress of Solitude the last great collection of kryptonian knowledge. Five years have since passed and my son has embraced his destiny though he does not live among the humans as I had hoped his experience with humans has caused him to become socially withdrawn he lives in the shadows a silent protector. I do not know if the humans are aware of what he has done for them though it's unlikely.
My son is not alone in his quest to protect the earth he has made allies of some very remarkable people they do not support his decision to live in the shadows but they do understand his reasons. However there comes a time when no matter what your sins you must step out of the darkness and into the light.
