Dragon King: The Fighting Game, (Japanese 格闘ゲーム竜王 Kakuto-Gemu Ryuo), was an unfinished low budget 3-D fighting game, and was the first in a planned series of fighting video games. The game was originally planned for the SNES using the Super FX Chip, but was later moved to the Nintendo 64, where it was to make unique use of the joystick on the controller. After deciding to use Nintendo characters to give it a more proper atmosphere on the N64, the game became Super Smash Bros., which became a huge success and spawned two even more successful sequels.
- In the only screenshots released of the game, the background of the stage the unnamed characters are fighting on is that of the Ryuoh-cho neighborhood, the location of developer HAL Laboratory's Yamanashi headquarters.
