The Legend of Tarzan is purely fictional. It's a work of imagination that combines adventure and fantasy elements to create an entertaining story, not based on real events or people.
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.
One main element is the idea of a human raised in the wild. Tarzan was brought up by apes, which is a central part of the real - story basis. Another is his struggle between his wild upbringing and his human heritage. He has to figure out his place in both the jungle world and the human world.
One of the main themes is the idea of the 'civilized' world versus the 'wild' world. Tarzan is caught between his upbringing in the jungle and his connection to the human society that he discovers. Another theme is love, as seen in his relationship with Jane. Also, survival is a key theme as Tarzan has to constantly fight for his life and adapt to different situations in the jungle.
Tarzan himself is the most important character. He is the main focus of the story, a man - boy raised by apes in the jungle. Then there's Jane. She is the love interest of Tarzan and represents the civilized world. Kerchak, the leader of the ape tribe that raised Tarzan, is also very important as he has a big influence on Tarzan's early life.
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.
