- Alas, Poor Scrappy: Averted with Mr. Arrow. Long John Silver kills him... and he's missed by no-one. Well, Long John claims he killed him; there's a reason everyone immediately assumes he wandered off the side in a drunken stupor. In the Sky 1 adaptation, he is keel-hauled after striking Squire Trelawney in a drunken rage. His death is mourned by Jim, which proves to be important; hiding inside a barrel of apples, Jim overhears Long John Silver conspiring with the crew.
- Evil Is Cool: Long John Silver is one of the most iconic villains in literature and is known for his charisma and amiable personality. It's been believed that Robert Louis Stevenson may have deliberately invoked this both with Silver and with Blind Pew as he was a physically frail man, so he must have had some inspiration to create villains who were a threat in spite of their impairments.
- Fair for Its Day: A rare villainous example. When Long John Silver and Pew were written as a cripple and a blind respectively, it was to show that they were threatening, capable, badass pirates in spite of their disabilities. These days though, they're often used as the prime example of the Evil Cripple stereotype.
- It Was His Sled: Long John Silver is a pirate.
- Magnificent Bastard: Long John Silver shows why he was the only man the ruthless Captain Flint ever feared. Getting himself hired by young hero Jim Hawkins, Silver converts the crew to his side and launches a mutiny, personally disposing of the only members who refused to join him. Silver proceeds to twist the events of the novel to his advantage to obtain the treasure he craves, while genuinely bonding with young Jim and becoming a mentor and father figure to the boy. When things go wrong and the crew betrays him, Silver promptly switches sides to the heroes and comes out on top, escaping their custody with a fortune to return to his wife a wealthy and free man. So charismatic and complex is Silver that even the heroes who have been under threat from him can almost hope that Silver will indeed escape justice.
- Memetic Mutation: In a meta-level sense, the portrayal of pirates in Treasure Island has leaked into popular culture, such that even Space and Sky Pirates tend to emulate some of the piratical behaviours as portrayed in this story.
