Black Monday was a combination of Batman and Solomon Grundy from the Dark Multiverse.

Black Monday was an evil combination of Batman and Solomon Grundy from the Dark Multiverse. Like Grundy, he spoke incoherently. He was recruited into the Dark Knights by the Batman Who Laughs for his invasion on Earth 0 under a pact with Perpetua and acted as a guard for Castle Bat. Wonder Woman, Batman, Superman, Harley Quinn and Jonah Hex tried to sneak into Castle Bat through a tunnel built by Swamp Thing while assuming they had been masked by Jarro. Monday and the other Dark Knights however were ready for them and blowed down the tunnel wall as they neared its end. He fought Superman who struggled to beat him, but Jarro split them up from the heroes from the Dark Knights by controlling Castle Bat's mind.[1]



  • His name refers to the color of the Batsuit and the nursery rhyme from which the supervillain Solomon Grundy derives his name.
