I'm not sure exactly how many are on the list you mentioned. There are quite a few, with Edgar Rice Burroughs writing many Tarzan novels over the years.
The new Tarzan novel might have more complex character development. Tarzan could be presented with new challenges that test his physical and mental strength in different ways compared to the original stories.
One of the main themes is the concept of the 'noble savage'. Tarzan, raised in the wild, has a pure and uncorrupted nature at first. Another theme is survival. He has to constantly adapt to the harsh jungle environment to stay alive.
Tarzan himself is of course the most important. He is the main character around whom the whole story revolves. Then there's Jane, who becomes an important figure in Tarzan's life and their relationship is a key part of the story.
Tarzan is purely fictional. The character and the adventures associated with him were made up for entertainment. There's no historical basis or real events behind it.
Tarzan's story is purely fictional. It doesn't have any basis in reality. It's a creation that has captured people's imaginations over the years through books and movies.
Definitely not real. Tarzan is a fictional character. The story is a product of the author's imagination. It doesn't represent any actual historical or factual events or individuals.
