Origin
Kruzado was one of many members of the Anti-Registration Underground. She was arrested by S.H.I.E.L.D. when they discovered the location of the Underground and presumably taken to 42, a prison in The Negative Zone.
Creation
Kruzado was created by Paul Jenkins and Ramon Bachs, with her first (and only) appearance being in Civil War: Front Line #4 – Embedded, Part 4.
