Widower was a notorious space pirate in charge of her own gang. During a preparation for a massive heist they teamed up with Zeta Flight led by Corporal Carol Danvers, but Widower soon learned that Danvers was about to backstab her and cut her team out of the loot. Her team's Quinjets attacked the Zeta Flight Space Station, but Zetas drove them off with their Zeta Fighters. Widower then confronted Danvers face-to-face all while Zetas were wondering about the reasons for the hostility. Widower revealed to everyone that Danvers was about to go back on their deal, shocking Zetas who up until then remained unaware of their leader's plans. Widower then left, telling Danvers that without her protection there was nowhere for her to hide.
However, Widowed soon confirmed that Zetas didn't steal her haul, which left only one other crew who could have done it - Ravagers led by Lord Starkill. Widower joined the Zetas in their assault on the Ravagers' asteroid hideout, but they were outmatched and everyone was captured. Starkill had the idea of selling his captives to the peacekeeper Thanos the Just in order to clear his own name, but the the rest of the Ravagers found his plan extremely dangerous and foolhardy. Meanwhile, Zetas have also grown tired of their leader's questionable leadership of late and so the two groups sided together in a shared mutiny against their captains, deciding to deliver both of them to Thanos. Upon landing on Titan, they were taken by him to the Court of Galactic Justice. Thanos found the lives of two criminals incapable of redemption worth nothing to hand over in exchange until Rockette revealed the Reality Stone taken from Lord Starkill. Thanos then ordered every pirate seized and announced his intention to use the Stone to rid of the galaxy of all who pirate and pillage like they do. Upon hearing that, the Widower attacked attacked Thanos' forces with the other pirates joining in, helping their captains espace and also robbing the treasury on their way back to the ship.
