Jim Hawkins is the main protagonist of Treasure Planet; he is a reckless juvenille delinquent who goes on the adventure of his life when he and Dr. Doppler go on adventure to search for the famous Treasure Planet and get enough to reopen the Binenbow inn when it was blown up. He has brown hair with a small ponytail, blue eyes, a yellow shirt, a black shirt, grey pants, a brown pants and black boots; he's voiced by Joseph Gordon Levitt.
As a little boy, he admired stories of the legendary space pirate, Captain Nathaniel Flint. But then his father, Leland, abandoned Jim and his mother when he felt he couldn't handle the responsibility of being a husband and father. As Jim grew older, he became a rebellious teenager, soaring a solar surfer and getting in trouble with the police.
Jim felt guilty after hearing his mother discuss her troubles with Dr. Doppler. Then, Jim found a crashing spacer named Billy Bones who had a special chest that contained something a mysterious cyborg was after.
Jim discovered that inside Bones' chest was a map. This map led to Treasure Planet, encouraging him to embark on a life-changing adventure, accompanied by Dr. Doppler.
Jim was assigned as a cabin boy for John Silver, the ship's cook and a cyborg. At first, Jim did not trust him because of the mysterious cyborg that was after Billy Bones, and Silver drove him crazy with chores. But as the voyage's time passed, Jim and Silver had a father-son relationship, which Jim never had.
However, Jim and Silver had some friendship flip-flops. When Jim's confidence was low about failing to keep Mr. Arrow, the captain's first mate, alive from a space storm, Silver did not tell Jim that his monstrous nemesis, Scroop murdered him.
Jim later found that out when eavesdropping on his conversation with the rest of the crew about mutiny. Jim also learned that Silver cared more about the treasure than Jim, which left Jim heartbroken and hurt. After the pirates attacked and mutiny began, Silver tried to apologize to Jim about what he said. He explained that if Scroop and the other spacers knew he was kind, they both would've been killed.
Even when Silver made a bargain that would make up for this whole mess, Jim refused.
Both Jim and Silver vowed to make sure they get to the treasure before each other. Eventually, they did get to the treasure together, but only because of Silver's force.
When the planet's self-destruct mode was activated, Jim almost fell to his death. Silver had to choose between the treasure he's searched for years, and the young man he had to come to love, deep down. Silver chose Jim and they both had a part in saving the whole crew from destruction. Before Silver escaped, he and Jim had a heart-warming goodbye, and Silver asked his pet shift-shaper, Morph to remind Jim of him.
Silver also gave Jim a handful of Flint's treasure to help him rebuild the inn. Jim went home, used the treasure to rebuild the inn, and went to a heroic academy, where Captain Amelia recommended. Before the film ended, Jim saw a cloud-shaped version of Silver, whose cyborg eye twinkled at him.
In the "Mystery Case Files: the Fanfiction", he appears as one of the ghosts who lost his life to one of the Rings of Eternal LIfe, but his soul is saved by the MCF. It may be possible that he'll appear ressurrected later on in a future story
