One drunken man staggered onto the stage to accept her challenge, making her move by insulting her Maori heritage rather than physically moving her. Angered, she immediately struck out at him and instigated a small brawl, tearing through the crowd before someone hastily drew their firearm on her and shot, only to find that not even bullets affected her. Before the now-turned mob could attack her, Zoom, accompanied by his newly recruited acolytes the Folded Man and Magali, appeared and teleported her outside of the carnival grounds. Being offered the chance to embrace her abilities and live as a godlike being after mastering them, she did not hesitate to join Zoom and his quest to kill the "evil" Flash.
