Hollow Knight: Silksong
Originally, Hornet was planned as a second playable character to be included in a downloadable content pack (DLC) for Hollow Knight, funded as a stretch goal in the game's Kickstarter campaign.  Eventually, Team Cherry decided to expand the DLC to a full sequel. While in the process, Team Cherry revealed some of the character animations for Hornet and Steel Assassin Sharpe, a villain from the game.
