Prior to launching the second Genesis Wave with Dr. Eggman, Dr. Wily had created a number of Robot Masters that served as his minions. These Robot Masters joined him the Skull Egg Zone to help construct the Wily Egg, from which the Genesis Wave was launched. Almost immediately upon his home reality being altered, Wily became aware of a multitude of other Robot Masters he had employed in the altered timeline and eagerly began making plans to recreate them as part of a Robot Master Army.

In order to gather subjects, Wily deployed one of his Robot Masters-the powerful Bass-alongside Eggman's Metal Sonic v3.0. (MM: #24)
