At some point after his invasion, Dr. Eggman seized the Roboticizer for himself and began using it to transform a sizeable amount of Mobians into emotionless Robian slaves until the device was rendered ineffective. When Eggman reset the Prime Zone with the second Genesis Wave, in collaboration with Dr. Wily, they used Roboticization, combined with robotic technology from Wily's native Earth in the year 20XX to turn Sonic's friends into the Roboticized Masters. Not long after, the same duo used a new roboticization procedure on Sonic to create Sonic Man.
