Warning: The following contains SPOILERS for Doomsday Clock #12.
The final issue of Doomsday Clock saw the Justice Society of America restored to the DC Comics universe. While individual members of the classic team have appeared sporadically in various titles, the organization as a whole has been largely absent since the New 52 reboot in 2011.
The plot of Doomsday Clock saw a group of heroes from the Watchmen universe follow Dr. Manhattan into the DC Universe, hoping to convince him to return to their world and save it. The story built to a final confrontation between Dr. Manhattan and Superman, who had become aware of how Dr. Manhattan had altered the timeline of his world. This caused both the Justice Society of America (JSA) and the Legion of Superheroes to never come into existence. Thankfully, the events of the final chapter of Doomsday Clock restored the timeline, bringing the pre-New 52 JSA into the fight alongside Superman.
The JSA was one of the first superhero teams in comic book history and was the first superhero team published by what would eventually become DC Comics. The current JSA line-up contains four generations of superheroes and several legacies, with many of the team's youngest members being the son, daughter or protege of at least one older superhero. Here's a rundown of Every JSA Member Just Returned To DC's Universe.

He is currently in the service of Jakeem Thunder.
Damage (Grant Emerson): The son of JSA founder Al "The Atom" Pratt, Grant Emerson was born with the metahuman ability to absorb energy and generate an energy field that temporarily increased his strength, durability, speed, and reflexes. He earned the codename Damage because failure to release this energy slowly results in Grant releasing all the energy he's holding in a single explosive blast.
