Rex Nebular and the Cosmic Gender Bender features gender swapping through the 'Cosmic Gender Bender', a machine designed to allow the 'Keepers' to change their sex for the purpose of imprenating the 'Stock women'. It is said in the game that users of the machine 'disgrace themselves', but that it is the only way to continue their race. The effects can apparently wear off at unexpected times, resulting in 'awkward' moments. At one point in the game, Rex attempts to escape and ends up inside the Cosmic Gender Bender, temporarily becoming a biological woman.
