Harley Quinn takes on her appearance from Injustice: Gods Among Us during the events of Alisa's Adventures in Rockoland, but she can't help her sleeping. She snores as well, which obviously infuriates Evil-Man.
Harley Quinn is voiced by Tara Strong, who previously voiced her in Batman: Arkham City and Injustice: Gods Among Us, in Alisa's Adventures in Rockoland.
