Brock grew up in the slums. His mother was neglectful and spent her money on drugs rather than food, but at least she never hit him.
He started running drugs and messages for the gangs when he was old enough to wander around alone after school. Anything to earn enough Petty cash enough to get a full belly. Eventually, he started doing more, because he’s not an idiot and he’s got a desire to prove he’s not worthless.
He’s good at what he does, but nothing can beat bad luck. HYDRA finds him in juvie and takes him into their system. Teaching him espionage until he ages out and sending him into the world as an agent.
He joins the marines first, wanting to make something of himself and proving his worth enough that the parent organization hiding in SHIELD picks him up. He works his way to the top to become the Handler to their best asset.
Then it all goes to hell…
