WARNING: The following contains spoilers for Dark Nights: Death Metal - Trinity Crisis #1 by Scott Snyder, Francis Manapul, Ian Herring and Tom Napolitano, on sale now.
In Dark Nights: Death Metal, the Batman Who Laughs took over a new version of reality by populating it with countless villainous versions of the Dark Knight. In fact, throughout the event, we've seen plenty of evil iterations of Batman-like the Bat-Mage, the Beyonder, B-Rex, Batrocitus, the Collector, Batmanhattan and the Night Glider. And that's not even mentioning all of those that didn't get names, like the Bane/Batman amalgam, the Judge Dredd Dark Knight or the Ra's Al Ghul Batman.
Now, Dark Nights: Death Metal - Trinity Crisis #1 takes things even further by introducing more of the Batman Who Laughs' evil enforcers. But these characters are not twisted Batmen -- some of them are actually characters closely related to Bruce Wayne in some way. And one of them is a young woman named Kull, the evil daughter of Batman and Wonder Woman.
Trinity Crisis #1 takes place right after the events of Death Metal #3. Batman and Wonder Woman have succeeded in freeing Superman and the rest of the superheroes from Darkfather, and they are now ready to enact a plan to steal the Crisis Energy from Perpetua. In order to do that, Clark, Bruce and Diana infiltrate the Batman Who Laughs' Castle Bat.
But when they do that, they are soon met with a legion of the villain's enforcers: a menacing monster named Chiroptor, the living embodiment of Arkham Asylum, called Ark, a villains Martha Wayne in a Bat-mech suit called the Pearl, a Solomon Grundy/Batman amalgam called Black Monday and Kull -- the daughter of the Dark Knight and the Amazon Princess.
Wonder Woman briefly faces Kull in battle, where the young woman reveals that Bruce and Diana are her parents in her Dark Multiverse world.
Kull wears a black and gold armor that mixes Wonder Woman's Amazon gear with the iconography of Batman: he sword features a Bat-logo crossguard, her tiara has the appropriate bat-ears and even her chest plate replaces Wonder Woman's classic eagle logo with the Caped Crusader's bat. Her brief tangle with Diana reveals that she has been trained to fight like an Amazon, which means she possesses the skills of both her parents -- something that effectively makes her one of the most dangerous warriors in the DC Multiverse.
The Dark Multiverse is home to plenty of alternate versions of the DC Universe characters. Batman and Wonder Woman have flirted with romance many times before, whether in the main continuity or outside of it. In fact, in the DC Animated Universe, the two characters grew extremely close, while other comics have shown a potential attraction between the two. Even 2017's Dark Nights: Batman: The Merciless #1 showed us a dark reality where Batman and Wonder Woman were a couple.
By introducing Kull, Trinity Crisis #1 teases a world where Batman and Wonder Woman took their attraction to the next level and have a child together. Kull's appearance in the book is all too brief, but this is a character who practically begs to have her full story, and her doubtlessly impressive feats explored in far greater detail.
