During the "Secret Wars" storyline, Black Swan and the rest of the Cabal worked with Maker into making a life-raft that would save them from the final incursion involving Earth-616 and Earth-1610 where it was deployed during the fight between both its inhabitants. Following the final incursion, Black Swan and the Cabal awoke in their life-raft when it landed on the patchwork planet called Battleworld. While Black Swan and the Cabal were fighting the Thor Corps, Sheriff Strange released the survivors of Earth-616 from their life-raft in hopes that they would confront the Cabal. Upon being teleported to Doomgard by Sheriff Strange, Black Swan was confronted by God Emperor Doom and ended up serving him. Black Swan was with God Emperor Doom's family when it came to the battle between Battleworld's inhabitants and God Emperor Doom's forces. When Black Swan confronted Star-Lord near the World Tree and defeated him, she was caught by surprise when Star-Lord managed to turn the World Tree into Groot, who defeated her.
