Captain Ahab.

The name Captain Ahab, is also an allegorical name to the biblical King Ahab. King Ahab is perceived as evil, and this trait is shown through Moby Dick's Captain Ahab. Captain Ahab's malevolent point of view derives from his determination to avenge his lost leg which was crushed by Moby Dick. This determination turns into an obsession, giving him an evil aspect, but that is just his tragic flaw, because every tragic hero has a tragic flaw. His heroic side holds determination, courage, and strength to be willing to go after a gigantic sperm whale with only one leg, making him not realize how inferior he is to the whale, but once again, he is obsessed. This obsession makes Ahab the antagonist of the book, but in an interesting way, Ahab is also the protagonist to the story. Melville's clever twist on the plot gives Ahab two different characteristics.
