History
Knight was a mutant who worked for the Kingpin, along with two others, King and Rook. During a business transaction with the Kingpin, they prevented the assassination of Klaw by Killmonger. Kingpin wanted Killmonger executed but they saw potential in Killmonger and hired him instead. The Kingpin sent them to defeat his best mercenary, Bullseye, fully well knowing that they would lose and Rook was killed.
Knight and Killmonger slept together. Black Widow suggested that she could help them lead a normal life if they turned King in. Knight agreed but Killmonger wanted to escape to Wakanda instead. Hiring mercenaries themselves they tracked King to Bulgaria, but in the ensuing firefight the mercenaries ended up killing King and his wife rather than capturing them. Knight escaped to London, whilst King made Killmonger promise to seek revenge on Knight.
Killmonger found Knight again in London under an assumed name and held her sister hostage. He also reported her crimes to Shield. When Shield came to arrest them Killmonger killed them all including Knight.
