She was one of the mediocre super-villains gathered by Dr. Angst to form the Band of the Bland. Angst had gathered them as part of a plot to assassinate then-presidential candidate Howard the Duck. Tillie and the rest believed that the reason for this attack was to raise their own profile, but in actuality Angst had been hired by an outside party to murder Howard. Tillie and the rest were also tricked into believing that their powers had been enhanced by a mystical element called Promethium, which was actually a placebo administered by Angst. The Band of the Bland confronted Howard at Doctor Strange's Sanctum Sanctorum where Howard was helped by the Defenders. The Defenders soon defeated the Band and they were presumably sent to prison. Years later, Tillie was released from prison and got a job as an aerobics instructor at a women's fitness club. Dr. Angst escaped from prison and approached Tillie, as well as the rest of the Band, reorganizing them to carry out his latest plot. This scheme became known as the Cosmic Squish Principle and involved releasing a large amount of pocket universes into their own dimension, thereby destroying the universe as it currently was, and creating a new world which the Band of the Bland would be the masters of. The Band were defeated by a group consisting of Howard the Duck, the She-Hulk, Louise Mason, The Terror, the Critic and Brent Wilcox. Tillie was defeated in battle by the She-Hulk.
