Persona
Jack Sparrow is noted for his unusual demeanor, characterized by a slightly drunken stagger, a wild, flailing arm and hand gestures that made him appear unfocused and possibly ataxic. This is possibly due in part to the hot climate of the Caribbean, and the large amount of time spent on deck of various ships—though it should be noted he seems fairly sure-footed onboard a ship. However, it is more likely that his demeanor is due to a common affliction of most sailors of that era - a combination of lots of rum, very few fruits and vegetables, and a tendency to accidentally hit one's head quite often on low-hanging bulkheads below the decks of a ship. It was rumored that Jack suffered heat stroke while marooned on a desert island after Hector Barbossa's mutiny aboard the Black Pearl. Jack's seemingly-perpetual drunkenness may have been the cause of his slurred speech. Jack can be extremely serious on occasion, such as after shooting Barbossa on Isla de Muerta.

Average in height and build, Sparrow relies more on intelligence, agility, and quick wit to protect himself, rather than physical strength. He frequently outmaneuvers enemies with his words, but when forced to fight he is still a formidable opponent. Sparrow is a decent, if self-serving, man who adheres to the Pirates' Code; he believes pirates can still be "good men," which was originally his evaluation of Bootstrap Bill Turner. Unusually altruistic for a pirate, Sparrow will risk himself to save others, most notably Will and Elizabeth Turner on multiple occasions. It was partly this benevolence that led the crew to the mutiny aboard the Black Pearl, according to Barbossa.
History
His early pirate life was the subject of many legends and rumors about his exploits, some of which were most likely mis-truths possibly made up by Sparrow himself to bolster his reputation. One of these legends told of how he sacked Port Nassau without firing a single shot, while his other notable exploits included impersonating an officer of the Spanish Royal Navy and a cleric of the Church of England. He became a friend with the infamous pirate Jolly Roger, who performed unsavory deeds for the Brethren Court, in hope of achieving a position among them. It was believed that Jack became chief of the Pelegostos in the years prior to meeting Elizabeth Swann, a tale he relayed to Mullroy and Murtogg at Port Royal. He picked up the cannibals' language which he again used during his second visit to their village to escape the Kraken. He also met Angelica, daughter of the notorious pirate Blackbeard, and they had a relationship together, but it didn't end well.

When Captain Teague left the Court to become a Keeper of the Code, he gave his seat to Jack. But instead of becoming a Pirate Lord of Madagascar, Jack chose the Caribbean Sea as his domain. He tied his piece of eight into his hair, letting it dangle over his trademark bandanna. Because of his position, it was possible that he kept in sporadic contact with his father. It is also known that during this time he had a sparrow tattooed on his arm to better identify himself to others as Captain Jack Sparrow. With the Black Pearl under his command, Jack recruited a crew in Tortuga, including Hector Barbossa, whom Jack named his First Mate. The crew had many adventures in the time after this but nothing could amount to what happened during the curse of the Black Pearl.

Jack went through many trials in the next years, which became well-known throughout the pirate community. He fought an army of the undead, cured them of their undead curse, was swallowed whole and digested by the Kraken, traveled to Davy Jones' locker and came back, assisted in the reconvening of the Pirate Lords and subsequent defeat of Davy Jones, and successfully eluded capture by the British Empire, the East India Trading Company, Davy Jones, and other pirates. Although he was eventually left with nothing but a small dinghy boat to cross the Atlantic Ocean with, he managed to commandeer a small trade vessel bound for England, stealing just enough money to get himself a new ship and begin collecting a new crew. Once he had acquired everything he needed, he once again set sail for the Fountain of Youth. Along the way, his crew managed to capture some hostages, and here the rest of his story begins.
Anything Else
Nothing; he is a simple man undergoing a simple mission on not-so-simple terms, especially with a full crew of ladies aboard.
