Joker

Notorious throughout Gotham City as the undisputed king of its criminal underworld and the man whom Harley Quinn deeply loves, he operates through a brand of madness that defies ordinary comprehension, sowing chaos wherever he treads. Rather than joining the party directly, he covertly infiltrates another world, concealing his true identity through transformation magic while pulling strings behind the scenes to manipulate the course of war for his own gain — making him an indispensable force shaping the entire narrative.
