Jaina Hudson was a Metahuman Gotham City socialite who came from a wrecked family. Hence, after the Superman arose, Jaina's Metahuman ability, the ability to be in two places at once, got her mingling in with the likes of Scarecrow and Bane.
Working under Bane's plan to have Gotham City handed over to him, the White Rabbit made her way into Arkham Asylum and fed inmates a new variant of the Fear Toxin. The White Rabbit proved to be a formidable foe, defeating the Batman in her first encounter and feeding the Flash the Fear Toxin as well. In the end, though, Hudson's taunting of the Batman proved to be futile as he, with the help of Superman and the Flash, managed to defeat Scarecrow and Bane. Following this, Jaina disappeared.
When the Secret Society took over, with Batman gone, did Jaina return. She began to reassociate herself with criminals as Dollhouse and awaited the upcoming war between her former benefactors, Scarecrow and Bane.
