Honestly my favorite character of the whole movie of Treasure Planet has to be Long John Silver. Even though he is a sort of a villain of the movie but I’ve always love how much of a father figure he is for Jim Hawkins in the movie.
Also his “You got the makings of greatness in you, but you got to take the helm and chart your own course. Stick to it, no matter the squalls!” is my favorite quote from this movie
