The Doughnut Maker is a sentient robot from the 2017 Continuum.
The robotic Doughnut Maker's creation was undertaken by Fenton Crackshell-Cabrera in 2019 in order to get his mother the cinnamon-flavored doughnuts she so desired for her birthday. While Fenton went off as Gizmoduck to prevent a robbery, however, Gyro Gearloose stumbled upon the unfinished prototype and decided to make his own improvements.
This cursory interference by Gyro was enough for the robot to turn sentient and evil, like all of Gyro's robots. The Doughnut Maker proceeded to run amok in Duckburg, using its high-pressure spray of dough paste as a weapon, until Gizmoduck and Fethry Duck managed to shut it down by reflecting the paste back at it and therefore putting its systems into overheat, as all exhale ports were jammed.
