Isekai Suicide Squad

Gorilla Grodd's time displacement machine transports many of Batman's worst enemies to feudal Japan - along with the Dark Knight and a few of his allies. The villains take over the forms of the feudal lords that rule the divided land, with the Joker taking the lead among the warring factions. As his traditional high-tech weaponry is exhausted almost immediately, Batman must rely on his intellect and his allies - including Catwoman and the extended Bat-family - to restore order to the land, and return to present-day Gotham City.

Joker: One Operation Joker is the Joker like you've never seen him before…as a single father?! After a fateful encounter with Batman that results in the Dark Knight de-aging to a baby, Joker takes it upon himself to raise the child into the crusader of justice! But does the Clown Prince of Crime really understand what it means to be Batman—or, more importantly, what it means to raise a baby all by yourself? (Source: DC Comics)
