Dural was mainly designed to showoff of the game's polygonal technology and was named after the character Duke Duralumin, the villain from the Princess Knight manga.

Akira Yuki was modeled after real-life martial artist Masaaki Satake. His choice of fighting style, Bajiquan (Hakkyouken), was inspired by the main martial art from the Kenji manga. According to an interview with the series creator Seiichi Ishii, the game was heavily influenced by the manga, to the point that one of the game's preliminary titles was Virtua Fighter Hakkyouken.

The initial idea behind the game wasn't a fighting game. According to series creator Yu Suzuki, after finding ways to have human polygonal models in Virtua Racing, they looked into making a sports game. However, due to technical limitations they could not animate a full sports team and settled for a game that only required two characters onscreen.

Pai Chan was also based on an ocha tea commercial actress.
