Morgan the Raider is a pirate.
That is how the man who has been chasing him for the past three years at the start of the first recorded adventure describes him. A pirate from another era, one of a particular breed who lived outside the boundaries of normal rules and regulations, gaining a reputation and following and loyalty such that over time they become almost a "government unto themselves". Such was how Morgan is described by one of the men tasked with tracking him down.
There is a lot of intended mystery to the backstory that is Morgan. Real name, for one. He is Morgan. First name? Last name? Not really stated but since he is called Mr. Morgan by at least one person, we will go with that.
Occupation? One does not put 'pirate' on any application but since Morgan is unlikely to be filling out any forms with the truth, that is not really an issue. If he did, though, it likely would have been 'entrepeneur' since that is how Morgan sees himself.
But 'pirate' is definitely how the rest of the world sees him. He might operate outside the laws of the land but he is not a snatch-and-grab kind of criminal. He has higher sights.
As the first adventure begins, Morgan is the unfortunate victim of a car chase having been in the wrong place at the wrong time when a punk fleeing the police smashed his car into the building Morgan was at. For the three previous years Morgan had lived on the lam, sought unsuccessfully by the Federal authorities even as he sought someone he very much wanted to get his hands on.
Before that, he was a 'guest' at a maximum security prison. He and an associate or two had plied his pirate trade on the byways of the Eastern seaboard and had intercepted an armored vehicle carrying $40 million in cash. The money and the culprits vanished. Some time later, though, a tip led the Feds to Morgan's doorstep where he was found with a few thousand of the booty cached away. It was not long before Morgan was locked away.
Someone like Morgan, though, does not like being locked up. He also does not like the idea of someone framing him and taking off with such a large sum as a result. Locked up was an inconvenience he overcame.
Which is why, when misfortune caused him to get recaptured, the CIA came calling. If he could get out of one of America's strongest prisons, he might get someone else out of a different establishment. So a Pirate becomes a Privateer.
The concept definitely fits someone like Morgan the Raider.
