A first-encounter story in which Superman meets his fellow superheroes Batman and Wonder Woman.
The story begins in a prologue, set in 2015. A trafficking ring housed in Gotham City processes several teenagers. They demonstrate latent superhuman abilities, and are kept in a cell separate from the others. At nightfall, the ring is attacked by the feared Batman, making his first full debut in the DCEU. Utterly dismantling the base of operations, Batman corners one of the mercenaries posted and demands to know who he's working for.
His interrogation methods are quick, ruthless and to the point akin to Rocksteady's Arkham series. The endangerment of children makes his debut here a tad forceful. As a veteran hero who's supposedly been acting for decades now, the Batman of this universe is in his prime. The mercenary, after being "persuaded", gives a name and provides a card marked with a symbol. The symbols of the ancient, feared order called the League of Assassins.
But when the mercenaries escape with the help of another metahuman, one demonstrating hydrokinetic powers, Batman realizes he may be in over his head. And he needs help. The meeting of the three heroes, the unveiling of the global threat they face and seeds of the Trinity's tight partnership.
