The Ace Attorney games released for the Nintendo 3DS contain a particular pattern of initially presenting a character's gender as male, only to later reveal them as having been female all along. Whether the writers were aware of this trend during development is unknown.

One of the developer illustrations in the Phoenix Wright: Ace Attorney - Dual Destinies art book features Miles Edgeworth dressed as Klavier Gavin.

Many of the original designs for Barok van Zieks looked very different than his final design.
