The Superhuman Restraint Unit, more commonly known as the Cape-Killers, are foot soldiers of S.H.I.E.L.D. equipped in armored suits during the "Civil War" crossover, where they are sent to bring in rogue superheroes.[2][3] The Superhuman Restraint Unit wear armor and use hardware designed by Stark Industries,[4] has two different styles of helmet (a riot protection helmet and a helmet with a gas mask)[5] as well as suits that are out-fitted with internal comm systems,[5]hover discs,[6]firearms equipped with tranquilizing darts,[2] and paralyzing lasers.[6]
The suits have been shown to be susceptible to power surges, with Nick Fury developing a device that transmits an electromagnetic pulse directly into their comm systems.[5] It is also shown that there is an override code used by the suit's designer that can freeze their suits.[7]
After the Gang War ends and Fisk's Anti-Vigilante Act is repealed, Cage orders the Cape Killers to disband, with its members either having their sentences commuted or returned to imprisonment. Although Cage lets Gao keep her title and has her transferred to a different department, Gao seeks out Rabble to form her own alliance in thwarting New York's superhuman activities.[14] Spider-Man narrowly defeats Rabble, freeing the Cape-Killers from her control. Gao escapes as Cage arrives and disbands the Cape-Killers.[15]
After the Cape-Killers disband, Julia Gao becomes a fugitive. She later becomes an avatar of Ares, assuming the name War-Cry.[16]
