Jungle Emperor Leo

Jungle Emperor Leo is a cancelled 64DD game from Nintendo. It was to be based on the 1997 anime film, based on the manga.

Gameplay
Jungle Emperor Leo was to be a 3D action game with vast open areas. It was to be like Banjo Kazooie but with a white lion cub as the protagonist. The plot just pretty much follows the animated film, with some liberties to benefit the gameplay.

Development
After the film's release, Shigeru Miyamoto wanted a tie-in game for the new 64DD. He requested that the original manga author's son, Makoto Tezuka, help work on it. Since Makoto Tezuka was too busy and unfamiliar with video games, it didn't go so well.

Cancellation
The game was first announced at the Shoshinkai Show in 1996. At Nintendo Space World 1998 a playable demo was presented. Since then the game had been delayed and then quietly cancelled.
