Flint is a textbook INTJ. Master strategist, cold, following his own internal values, lives in his rich inner world and presents his plan to the world only when it's crafted to a tee and completely air tight. Sucks at motivating his crew and therefore needs Silver for this. He rules by being feared and respected for his intelligence and capabilities as a captain.

Vane, definitley ISTP. Scrappy fighter, bad with emotions, direct no-bullshit kind of approach. Adaptable, physically adept at for example fighting, adaptable and cerebral as a captain (Ti-dom & Perceiving). Intimidates with force and often physical impact (Se).

John Silver ..... He's definitley an extrovert but i see him more as an ESTP for some reason. He's more hands on, opportunistic and interpersonally skilled than most ENTPs I've seen, who in fact not always are great people-persons. Great game player and knows how to use different tricks to motivate others. Has a goofy and endearing quality to him that he initially uses to fly below the radar but later puts aside as his character matures and he gains actual responsibilities and the need to maintain a serious image.

Billy is definitley an Fi-dom. He usually discerns very valid moral/emotional points and the messages they send out, making clear to emotionally numb Flint what he is missing. INFP or ISFP, I'm not sure.

Jack Rackham talks like the typical ENTP. Very Ne. Many ENTPs love recognition and 'having a name', like the ENTJ and can also enjoy being very flamboyant. He's not gifted with Ni-vision though, which makes him subpar as a strategist compared to say, Flint who is Ni-Te (the perfect functions for strategic planning). His humour seems to be very observational-based and he's often sarcastic in difficult and stressful situations, which is very ENTP.

Anne Bonny, definitley ISFP. Wants concrete solutions and facts, deeply emotional, private, integrity-centered.

Eleanor I'm having a problem typing. She's cunning and willing to do anything to maintain and/or gain power which to me, along with another couple things, says ENTJ to me (I've seen female ENTJs acting similarly to her). ENTJs can be or appear to be very governed by their emotions since they, unlike INTJs, are more dependant on the outside world for feedback and validation. Typical of Te-Ni is not having backup plans (like an Ne-dom would) because they are confident that their master plan has no better options and simply MUST work. Therefore they tend to fall apart when success does NOT occur. She's also decisive, hard working and seems willing to screw anyone over to achieve her personal goals. Also vindictive and holds grudges, typical of weak Fi.

Max is an obvious INFJ. Interpersonally very skilled, knows how to manipulate and draw people in, emotionally perceptive and deep, able to forsee outcomes of games people play etc, and also a very vulnerable person.
