Powers: Man-Killer wears an exo-skeleton which augments her strength seven times - to class 10.
Bio: Katrina developed an extreme hatred of men after a skiing contest and subsequent accident with a violent anti-women's-liberation male. A militant group of feminists funded her recovery and granted her the exo-skeleton which gives her her strength.
After a brief solo stint as hired muscle, Man-Killer joined the Crimson Cowl's Masters of Evil.
Under the new code-name of Amazon, Katrina joined Hawkeye's Thunderbolt team (the one that replaced the missing team).
Currently, Man-Killer is working for Helmut Zemo's new group, working to possibly save the world...
Notes: Quite possibly created after Woman's activist Wilma Mankiller (Katrina used the alias Wilma for a short while).
