History
In Jungle Emperor
Leo here is much the same as he is the TV series, with minor differences. At the beginning of the story, he has more anthropomorphic features (including dressing trousers). The final ending of the story it's different from the one of Leo the Lion and was more faithfully represented in Jungle Emperor Leo.
In Kimba the White Lion
Kimba is kind, caring cub who always looks out for his friends. Innocent and idealistic, he sees the world of humans and tries to use it to make the lives of his animal friends better, but this is slow process. He is determined and loyal, and often goes out of his way to avoid a fight, though he sometimes loses his temper.
In Leo the Lion
Now an adult, Kimba has grown into a fine lion. He still has occasional issues with his anger, but is otherwise a fair and kind ruler. When his cubs are born, he is over-joyed. However he quickly establishes himself as a stern father, helping Rune "run away" from home. All in all, he is very much the same, except grown up. The series however show more episodes with Kimba fighting or wounding and even killing his opponents. The ending of the series differs from the original manga (Jungle Emperor).
In Jungle Emperor (1989)
Leo is shown as an older cub (not yet adult but older than in "Kimba the White Lion"). The series explores more dark aspects of the character, including a brief arc of episodes when Leo chooses a voluntary exile from the Jungle. In the last episodes of the series is revealed that Leo (differently from the other adaptation) hunts for prey.
In Jungle Emperor Leo
Leo is shown to be a serious character, refusing to fight unless he has to, but prone to protective anger. He is a caring father and a loyal friend. In the beginning of this film, Leo is an adult and has just learned that his mate, Lyra, has given birth to twin cubs: Lune and Lukio, much to Leo's joy.

As the movie progresses, Leo continues to protect the animals of the jungle from whatever may threaten them, including Ham Egg's sinister actions, dissent amongst the animals, and a deadly disease that is affecting the animals. The lion leads Dr. Mustache and his assistant to Mt. Moon, and he sacrifices himself by falling on Dr. Mustache's kris so that Dr. Mustache will have food and shelter from the cold.
In Jungle Emperor: The Brave Can Change the Future
Leo here is vastly different from any other portrayal of him. He is friendly, but easily frightened and has low self-esteem. He looks up to his father, and tries to prove he is as worthy of respect as Panja is.
