The New Adventures of Kimba The White Lion

The series follows the adventures Leo, a young lion cub. Leo becomes king of the jungle when his father, the previous king of the jungle is killed by a human hunter.

This movie focuses on the last half of Osamu Tezuka's revered saga of a white lion's quest to become king of the jungle. Leo's newborn cub, Lune, takes an interest to humans after discovering a music box in the wreckage of an airplane. At the same time, a greedy treasure hunter known as Ham Egg is leading an expedition team of rough-looking men on a trek for the fabled Moonlight Stones, which can supposedly save the world from an energy crisis. Two other humans, (who go by the rather wacky names of Dr. Moustache and Lemonade) try to stop Ham Egg's mad destruction of the jungle. Later, a terrible virus sweeps through the jungle, poisoning many of the animals. Dr. Moustache comes to save them with a cure. The film culminates with a treacherous journey up the legendary Mt. Moon in search of the stones....

Earth, sometime in the 21st century. Because of non-stop environmental destruction, the United Nations commissions a private company, "Eternal Earth", to create an artificial jungle, to be a nature preserve and to protect animals. All wild animals are forced to live in it. The animals that live in this "neo-jungle" have an easy life. Leo, son of Panja, is born in this artificial world. Because of the unrealistic nature of the neo-jungle, Leo lives his life like he hasn't a care in the world. But Leo is ridiculed by the other animals; they call him a coward--he is not like his father, the great Jungle Emperor, but Leo vows that some day he will be. Kenichi, son of the Eternal Earth company's CEO, has no doubt about the great success of the neo-jungle. The story starts when Leo and Kenichi meet. Kenichi has the special ability to understand what the animals are saying.

The first 2 minutes of this film are taken from the Jungle Emperor Leo (1965) TV series, while the rest is all original. Tezuka was very pleased that this film conveyed his story accurately, something he wasn't able to do with the TV series.
