Fortnite Chapter 7 Season 3's "Hot Bat Summer" update has introduced both Catwoman and Harley Quinn to the game's island, offering players the chance to hire them or challenge them for unique rewards. These characters are not listed on the in-game Characters map, requiring players to seek them out directly.

Catwoman can be found on a beach located south of Wonkeeland and west of the Bat Cave. Players are advised to reach her location early in a match, as she becomes unavailable for interaction if another player hires or defeats her first. Upon finding Catwoman, players have two options: hire her as a Scout Specialist for 350 gold bars, or engage her in a duel. As a Scout Specialist, she will mark nearby enemies and chests. If chosen, the duel will immediately begin with Catwoman gaining a shield and health. She primarily uses a leaping attack, but defeating her will result in her dropping Catwoman's mythic rapidfire SMG and a Batman sprite.

Harley Quinn is situated on a beach west of Sinister Strip. Players should head west from Sinister Strip until they reach the river, then proceed slightly south to find her. Similar to Catwoman, it is recommended to reach Harley Quinn as quickly as possible, as she will not be available for interaction if already engaged by another player. At her location, players can choose to hire her as a Scout Specialist for 350 gold bars, or initiate a duel. If hired, she will provide intel on enemy positions and chests. In a duel, Harley Quinn becomes aggressive and attacks immediately. She is described as a relatively easy boss to defeat, requiring players to deplete her health. Upon her defeat, she will drop Harley Quinn's mythic warforged AR and a Batman sprite. Harley Quinn standing on a beach with its location marked on the Fortnite map.
