The Inspector was a comic book character created by Hubris Comics. She has a comic series that was planned to be distributed for the first half of 2078. Because of the Great War, the series was never produced.
She appeared in the Unstoppables comic series. Dressed similarly to a circus ringmaster, her powers, weapons, and abilities are unknown except for being some kind of detective. On the Dr. Brainwash cover, she seems to be holding her hands out with white tendrils coming out of them. This may mean she uses magic, similar to Zatanna, though she could simply be a martial artist and the white tendrils are simply a visual effect.
