The Wily Rejects are a group of Robot Masters who were for one reason or another rejected and decommissioned by Dr. Wily. Eventually however Dr. Wily needed Robot Masters for his plans but didn't have the time to build a new batch so simply dusted off some of his decommissioned prototypes to spare him some time, not expecting them to last long. Ultimately they failed even faster than Dr. Wily had anticipated and he was once again defeated by Mega Man.
