Atom (real name Ray Palmer) is a member of the Justice League. He is a molecular physicist in Ivy Town, and mentor of Bumblebee.

Physical appearance

Ray Palmer is a tall Caucasian male with brown hair and blue eyes.[1] As the Atom, he wears a skintight costume that is red from the abdomen down, and blue from the chest up, with a visorless cowel over his head, which is adorned with an atomic whirl. The suit has bright red line patterns in the red sections and on the arms and cowl.[5]


Early life

Ray Palmer is a leading expert[6] in molecular physics.[7] He became the Atom in 2003.[8]


The Watchtower
November 25, 06:54 EST

Atom was considered for membership during the meeting of the Justice League. Captain Marvel questioned whether his size was a valuable addition to the League, but Batman spoke in the Atom's favor.[5] It was eventually decided that Atom could join.[4]

Washington, D.C.
December 30, 09:16 EST

With the other inductees into the League, Atom was welcomed to the Hall of Justice and given an official membership pass along with Plastic Man, Doctor Fate, Icon and Red Arrow. Because the card was bigger than him at the time, Atom had some trouble holding it.[4]

The Watchtower
December 30, 23:46 EST

After being made a slave of the Light's mind control, Atom welcomed Vandal Savage aboard the Watchtower with a silent kneel of obedience.[4]

Still under mind control, Atom was slicing the remaining piece of Starro with a laser scapel, when suddenly, a Starro slice floated. He changed his size to grab it, but in the process was tagged with cure-tech by Miss Martian, and went unconscious.[9]


Atom took on Karen Beecher as his lab assistant.[1]

December 1, 13:45 EST

Atom was one of a number of Justice League members who responded to the emergency in Metropolis. Even at his minimum size, he was unable to get through the force field surrounding the city. He asked Red Tornado for the whereabouts of the other Leaguers.[10]

December 1, 16:22 EST

The alien ship firing an apparently ineffectual beam of energy at the force field caused Atom to realize the field was probably generated from the inside. Nightwing communicated the information to the heroes trapped in the field.[10]

December 1, 17:45 EST

Martian Manhunter, the Atom, and the Flash snuck aboard the alien vessel, and were soon approached by the Collector of Worlds. Atom made a futile attempt to attack the Collector while he was distracted, before immediately being spotted and dropped to the ground. The heroes were quickly defeated, and dropped, via a hatch, from the Collector's ship.[11]

December 1, 18:16 EST

The three heroes fell on top of the bottle.[12]

December 1, 18:20 EST

After Nightwing contacted Martian Manhunter that they were inside the ship, J'onn lifted Flash and Atom to safety.[12]

The Collector's Ship
December 1, 19:01 EST

Flash and Atom made it back inside the ship, and met up with Alpha Squad at exactly the same time as former prisoners of Kylstar, who were teleported aboard. Lagoon Boy used the Bio-Ship's cannon to destroy the coludroid.[13]

December 1, 19:03 EST

Dozens more coludroids showed up and surrounded the heroes. Nightwing and Atom persuaded the Collector to shut down the beam that shrunk the city.[13]

December 1, 22:03 EST

Back on the ground, Atom listened to Captain Atom and Nightwing as they discussed what to do next.[13]


New Orleans
January 4, post-21:59 CST

After Gamma Squad saved hostages from the Kroloteans, Atom arrived on the scene with the rest of the Justice League members and the Team, riding on Flash's shoulder.[14]

Ivy Town
March 23, post-20:20 EDT

Dr. Palmer checked in on research from his assistant, Karen Beecher. He greeted Mal Duncan, before taking a look at Karen's work. To compare results against the white dwarf fragment, he committed to several hours of work with her. Mal dismally left without them noticing.[1]

Ivy Town
April 7, 23:24 EDT

Atom and Bumblebee tried to get Jaime's scarab off his spine by going inside his body. Atom used a laser to try and cut the scarab open, but the defenses proved too tough. They had to be extracted from the body. Once outside and back to normal size, Atom informed Jaime that he didn't think the scarab could be removed without killing him.[15]

The Warworld
May 30, 10:36 UTC

The Atom, along with Aquaman and Flash, guarded the Warworld's crystal key chamber.[16]

June 20, 08:16 EDT

When magnetic field disruptors planted by the Reach threatened the Earth, Atom joined 39 other heroes of Earth in a briefing in Metropolis. The heroes would use a computer virus provided by Lex Luthor to safely disable the disruptors. The heroes were paired off with another into twenty squads: one member would run interference against weapons guarding the disruptors, allowing the other to get close enough to plant the virus.[17]

Atom was assigned to Omicron Squad, and worked alongside Tye Longshadow.[18] Within thirty minutes, all squads had succeeded in their mission.[17]

The Watchtower
July 4, 21:16 EDT

When the Team was summoned to the mission room for a face-to-face meeting with members of the League, Atom was among the leaguers present. Batman informed them that they would now operate side-by-side with the Justice League from the Watchtower. Not because Mount Justice was destroyed, but because they earned the right to do so. The League then left the Team to its own devices.[17]


The Watchtower
February 24, 19:00 EST

Atom was standing on Flash's shoulder during Justice League, the Team, Outsiders and Batman's team briefing.
