Guide Mentor
Character Role Analysis
Pippi's Father
Who? Yeah, we know he's not actually in the book—at all—but at the start, we learn that Pippi was raised to age nine by her sea captain father, and that he took her with him on all of his voyages. We also know that she doesn't believe he's dead, but thinks instead that he is living as a cannibal king on a deserted island, and that he will come for her as soon as he can build a boat.
Add to that the fact that her dad's the one who procured Villa Villekulla and the number of times she invokes him to explain her own behavior ("when you have a father who is a cannibal king"), and all the treasures she has to remind her of her time with him, and we think we've got a solid case for him serving as her Guide Mentor.
