Alas, The Mad Catter!
From Jenny Everywhere Wiki
The cover of Sensation Adventures #9, which printed Alas, The Mad Catter!. (PROSE: Sensation Adventures feat Centennia)
In one universe, Centennia, a real heroine in Reality Z-25 31-H, was instead a fictional superhero character. She existed as early as the “Golden Age” in the comics, when her rather campy adventures were printed in Sensation Adventures; by the mid-2010s, an issue from these early years, such as Issue #9, which printed Alas, The Mad Catter!, was a very valuable collectors' item.
