In the 1993 JoJo RPG for the SNES, Midler was portrayed as a stewardess, making it the first time she had a physical appearance. Seven years later, when Capcom was producing JoJo's Bizarre Adventure, they wanted to include Midler as a playable fighter in the game. However, as she was only shown from the waist-down in the manga, and the game was a more faithful adaptation of the source material, they asked Hirohiko Araki to redesign her into something like a belly-dancer with her face covered up. Since then, as shown in the JOJO A-GO!GO! artbook, this new look is now her default appearance.

Unused sprites for Tower of Gray/Gray Fly can be accessed via the game's debug menu. Information for assembling the sprite is unfinished, and thus uses Jotaro's sprite assembly method instead. The sprites for Gray Fly are mostly finished, which includes various attacks and death animations.

These sprites would later be used in the PSX port, where Gray Fly is an enemy in Super Story Mode.
