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.

Despero, however, thinks they’re after the Cosmic Egg which he is in possession of then tells them that he is not auditioning for them, but they for him.

In Rabat, Morocco, Superman finishes a battle with Firebug and a giant robot and, with no alternative, throws it into orbit to be taken care of later. While signing autographs for the locals he hears the heartbeat of some go up, understandably, but the scared still feels “wrong” to him, like things should be different.

Etta Candy and Diana of Themyscira walk through a mall “dishing” about Diana’s relationship with Tom Tresser and the private lives of superheroes in general prompting Diana to ask what people think about Batman and Superman. Etta says that people view Superman as a cool, protective big brother while Batman is scary but people are glad he exists. About Wonder Woman, Etta says she’s a “warrior, not a buddy” and since she’s hear to change the world, some people may not take that easily. To herself Wonder Woman decides that that is how people see them, but something feels off, like something is going on.
