This was a weekly year-long event, similar to “52” and “Countdown” but unlike the latter, it was an entirely self-contained story. Unlike either of its predecessors, however, it focused on the major super-heroes of the DC Universe, Superman, Batman, and Wonder Woman, instead of the lesser developed characters.
Each issue of Trinity had two stories; the main one, focusing on the Trinity themselves, and the backup, focusing on other characters involved in the overall storyline.
Holed up in a warehouse for safekeeping after her recent super-villain attack, Marguerita Covas turns back to her Tarot cards looking for a real way out of her predicament. Her readings keep coming up with variations of the same theme, different Trinities, and once again the images change–this time on all of the cards–to images of Batman, Superman, and Wonder Woman and she throws them down.
Aboard the Justice League’s orbiting Watchtower, Superman, Batman and Wonder Woman begin discussing their recent dreams and mysterious threat when Batman notices that the burn on Wonder Woman’s back changes from one symbol to another, neither one they recognize, while he’s cleaning it. The three of them then discuss the Beast Batman captured calling them a “Trinity” and analyze the many different ways they fit into such a criteria.
Covas, deciding to trust the cards, once again feels the energy connecting her to the entire world “and beyond”. Giving in to it she sees the three heroes, realizing they’re a balance, and letting the energy guide her delves deeper into it’s meaning, relating it to all three heroes in different ways in different aspects of their lives as the cards show them to her.
She realizes they’re “three faces of the same idea” and “in the middle of everything, which they may not even know. She decides she wants to relay the message to them, but before she can think on it further part of the warehouse wall collapses as three beasts crush Gangbuster into it. They snatch Rita up and run away, leaving Gangbuster unable to rescue her as he falls unconscious.
