Katee Sackhoff returns as Poison Ivy from ''WesternAnimation/BatmanTheLongHalloween'', Zach Callison returning from ''WesternAnimation/Injustice2021'' as Damian Wayne, Troy Baker as the regular Joker who he first did in ''VideoGame/BatmanArkhamOrigins'' and Keith Ferguson as Two-Face from ''WesternAnimation/BatmanVsTheTeenageMutantNinjaTurtles''.

So one can't help but feel DC/WB is "cleaning house" regarding its animation projects just like how DC Comics cleaned house with its multiverse through the original comic story.
