Darkwing Duck is a platform video game developed and published by Capcom for the Nintendo Entertainment System in 1992.

[8] A sequel to the game featuring 16-bit styled graphics was pitched to Capcom by Headcannon, one of the developers of Sonic Mania.

[24] In 2018, Aaron Sparrow, lead writer for The Duck Knight Returns comic, worked alongside Sonic Mania developer Headcannon (as well as its main developer Simon Thomley) and Disney comic artist James Silvani to create a proposal for Capcom to create a sequel to the NES video game Darkwing Duck.

[27] Headcannon created a short prototype of the game as part of this, and those involved said they would be attempting to get every member of the TV show's voice cast as they could.

[28][29] Aaron and Simon went into detail about the proposal in 2019, when the demonstration was released on Headcannon's official website for people to download, though it is shorter due to the rejection.

[25][29] Darkwing Duck uses pixel graphics, vintage music, and a two-dimensional perspective as well as similar gameplay to the original NES game with only a small number of changes and additions.

[27] It was meant to be either a spiritual sequel or, if Capcom desired, a remake of the original game in a similar style to DuckTales Remastered.

[25] The game would have featured animated art by James as well as fully voiced motion comics in between the stages.

[25][30] It would have taken place between the original TV show and Aaron's comic, featuring Darkwing Duck villains Steelbeak, Taurus Bulba, and the Fearsome Five.
