Tezuka Osamu's Jungle Emperor Leo

Somewhere in East Africa lives a white lion named Leo (Kimba grown up), ruler of the jungle. Leo lives happily with his wife, Riya (Kitty grown up), and their two children, Rune and Rukio. All is peaceful until one day when a ruthless mercenary and his group come to the jungle in search of the moonlight stones (ref. the Leo The Lion TV series, episode 8). Only concerned with making money, the humans have absolutely no regard for the animals they encounter. The animals quite naturally are opposed to the intruders storming their jungle. At the same time, a highly contagious disease sweeps through the jungle. Jungle Emperor Leo is based on the second half of Dr. Tezuka's original manga story. It keeps the basic story of the original manga even though Tezuka himself had changed the outcomes of the story in 1966 for his Leo The Lion TV series. I guess it was just a creative decision to revert to the older story of the manga, but a lot of people were severely traumatized by the movie. When they see Tezuka's revised story from the last two episodes of the Leo The Lion series, they're happy again.
