Albert Rothstein

The godson of Al Pratt, the Golden Age Atom, Albert Rothstein acquired his metahuman powers of super strength and control over his molecular structure, allowing him to alter the size and density of his body, from his grandfather, a reluctant supervillain known as Cyclotron.[4] This allowed him to fight crime first as Nuklon, and then, later, as Atom Smasher. As Nuklon, Albert was a charter member of Infinity, Inc. and subsequently served in the Justice League. He was considered a dependable, but rather insecure and indecisive superhero while in Infinity, Inc. During this time he had a mohawk haircut. While in the JLA, he forged a strong friendship with fellow former Infinity Inc. teammate Obsidian.

Albert finally gets his dream and is invited to join the reunited JSA under his new name and identity, Atom Smasher (he mocks his old mohawk and costume in the meantime). For years, Atom Smasher cherishes his role in upholding Pratt's legacy and constantly seeks to prove himself worthy to his Golden Age idols – especially when many of them became his teammates in the JSA. He looks up to the elder JSA members, but is himself looked up to by young rookie member Stargirl. When Albert's mother is murdered in a plane crash engineered by the terrorist Kobra, he becomes consumed by vengeance, nearly crushing Kobra in his hands before he is talked down by his teammate Jack Knight, who convinces him that he should not taint the memory of his mother by associating it with Kobra's murder. Not long after the fatal crash, Albert – with the aid of Metron of the New Gods – goes back in time and replaces his mother with the weakened villain Extant. This ends up saving her life but makes Albert a murderer, even if there was no other way to contain Extant and to stop him from causing further harm.

When Captain Marvel's longtime adversary Black Adam reforms and joins the JSA, he and Rothstein develop a rivalry at first as Al refuses to believe Adam has reformed. This soon turns to kinship after Adam justifies Al's murderous actions towards Extant. Indeed, Black Adam comments that he thinks of Atom Smasher as the brother he never had. Encouraged by Adam, Atom Smasher grows frustrated with the JSA's moral boundaries, especially when Kobra blackmails authorities into granting his release. Albert and Adam promptly quit the JSA after Kobra's escape.

Shortly thereafter, the unlikely duo settle each other's personal scores. Adam kills Kobra, while Rothstein kills the dictatorial president of Khandaq, Adam's home country. Atom Smasher helps lead a team of rogue metahumans (including former Infinity Inc. teammates Brainwave and Northwind) in an invasion of Khandaq and overthrow its oppressive regime. Atom Smasher initially fights against his JSA teammates in Khandaq before deciding instead to help forge an uneasy truce—Black Adam and his compatriots can remain in power so long as they never leave the country.

Atom Smasher remains in the Middle Eastern nation for a time, although he eventually begins to question Adam's motives. Rothstein perishes in JSA #75 while fighting against the Spectre, but is revived by Black Adam's lightning, and carried back to JSA headquarters.

He is later put on trial for his actions in Khandaq and pleads guilty to all charges. Teammate Stargirl promises to "be there for him" when he gets out. Whilst in jail, he is approached by the founder of the Suicide Squad, Amanda Waller. In 52, he is seen assembling a new Suicide Squad under Waller's orders, instructed to fight Black Adam, and, unbeknownst to Atom Smasher himself, push his family to overreact. They succeed, and Osiris is disgraced and exposed for having killed a Squad member, as Amanda Waller was filming the events, leading to the downfall of the whole Black Marvel Family, and a murderous rampage of Black Adam, dubbed World War III.

He then sides with the Justice Society, trying to apprehend Black Adam, but refuses to condemn him in any way, not even believing him guilty of the genocide in Bialya ("Tell me it wasn't you..."). When Adam is robbed of his powers by Captain Marvel, and is about to plunge to his death, it is Atom Smasher who saves him, though no character ever sees this, and Al keeps it hidden.[1]

In the Black Adam: The Dark Age series, Albert is shown searching for his former friend, who is intent upon resurrecting his dead wife Isis. In Black Adam #5, Albert brings Adam a bone from Isis' remains (unbeknownst to the JSA, with whom he was searching for Adam), and tries unsuccessfully to persuade his friend to go into hiding.

In the Justice Society of America: The Kingdom special, Stargirl recruits Atom Smasher to knock some sense into Damage, who has become an evangelist of sorts for the Third World god Gog after the cosmic being (temporarily) healed his scarred face. He views Pratt's son as a brother figure, since he was brought up by Pratt in the first place.

Atom Smasher finally returns to the JSA during the "Black Adam and Isis" arc printed in Justice Society of America #23–25. Asking the team for a second chance at honoring the memory of Al Pratt, Atom Smasher joins the Justice Society in battling Black Adam and Isis, who have robbed Captain Marvel of his powers and his throne at the Rock of Eternity. At the conclusion of the story, despite Wildcat's distrust, Atom Smasher is readmitted into the JSA as a full member,[5] along with all the other members of the team who had acted poorly in recent issues. He vanishes for several issues, but he reappears in the JSA: All-Stars book as a victim of kidnapping.

In the "Watchmen" sequel "Doomsday Clock," Atom Smasher returns to the DC Universe alongside the rest of the Justice Society of America when Doctor Manhattan, inspired by Superman, undoes the changes that he made to the timeline that erased the Justice Society of America and the Legion of Super-Heroes.[6]

Al was part of Superman's Justice League in Mark Waid and Alex Ross' Kingdom Come under the code-name "Atom Smasher". This was the debut of his new name, which was later used in mainstream DC continuity.

• In Justice League episode "Legends" a character named Tom Turbine voiced by Ted McGinley is based on Atom Smasher and Superman. Tom Turbine, was an alternate-Earth superhero and a member of the Justice Guild of America (based in Justice Society of America). During his time as a superhero, Tom Turbine battled the Injustice Guild. He died along with the rest of the JGA during a war that destroyed most of their world. He, along with the rest of the Justice Guild, "died" a second time defeating Ray Thompson, who had recreated them all, in an illusion of his past world. According to Bruce Timm, Tom Turbine was based primarily on the Golden Age Atom, Albert Pratt. Several characteristics of early Superman were incorporated into the character as well.

• In The Flash episode "Power Outage", Al Rothstein is mentioned as one of the people who seemingly died as a result of the particle accelerator accident that gave The Flash his powers. For the second season, Adam Copeland was cast as Atom Smasher debuting in the first episode "The Man Who Saved Central City". This Albert Rothstein is implied to be a metahuman from Earth-2. For some reason, he kills his counterpart in this universe who contradictory to "Power Outage," did not die in the accident and was in fact in Hawaii at the time. With this version, he is portrayed as a villain who comes to Central City on Earth-1 to kill the Flash at Zoom's request.[7] Gaining his powers by absorbing radiation in his vicinity, he is defeated when the Flash lures him into a nuclear reactor and exposes him to a lethal dose, Rothstein being unable to absorb all that energy. A dying Rothstein tells Flash that the person promised to take him home if he successfully defeated the Flash went by the name Zoom.

Atom Smasher is set to appear in the upcoming Black Adam film, set in the DC Extended Universe.[8]
