Volume 2, Issues 5 - 6[edit | edit source]

The villainous Countess arrives on Earth and places the city of Astoria, Oregon under her control. She also takes control of Nico and uses her to strip the superpowers from the other A-Force members. The Countess is not powerful enough to enslave the other team members, so she orders Nico to encase their feet in cement ("gangster's shoes") and drown them.
