Atom is a Legendary Warrior Champion who does Physical damage. Atom is best used in null.
They can be obtained in The Bleed, Motherboxes (Green, Blue, Purple, Yellow), Random Legendary Shard.
You should focus on the following transmutes for Atom: HP, Crit RES, ATK.
Atom saw a significant rework in 2025, taking his kit from utterly unusable to moderately effective against certain Training Simulator levels, and to an extent in PvP modes such as 3v3 Strategic Challenge. The stun on his ultimate, coupled with significant AoE damage prior to his departure from the battlefield, can be the push you need to complete levels you otherwise struggle with. He doesn't need much investment (if any), so he's just a good champion to have in your level sync just in case.
Strategy Guide
The Atom can deal devastating burst damage to all enemies and stun them by sacrificing himself.
Grants Atom a shield when his HP gets low. He stacks up Attack with basic attacks before unleashing explosive damage on all enemies. This shield keeps him alive long enough to build up Attack and deliver his devastating finisher.
Increases HP, Attack, and Crit Damage. Atom stacks up Attack with basic attacks. Higher Attack means bigger stacks, and more Crit Damage makes his finishing move hit even harder.
Increases HP and Attack, helping Atom survive longer and stack more Attack. Even if he's defeated, his passive skill deals damage and stuns nearby enemies.

Lore
Ray Palmer was a graduate student in physics at Ivy University when he discovered a white dwarf star fragment that had fallen to Earth. Testing a theory, Ray ground a lens from the fragment and focused ultraviolet light through it to shrink objects to a tiny fraction of their size. But the items were unstable and exploded soon after. Days later, Ray and others were trapped in a cave-in. Ray used the lens to shrink himself, thinking he'd have time to slip through small openings and save the others before he exploded. Surprisingly, he didn't explode, even after using the lens to return to normal size. He developed tech to control his mass as well as his size. Theorizing a unique genetic quirk (the metagene) let him survive the process, Ray adopted the heroic identity of the Atom.
The Atom battled criminals, aliens, and other extranormal threats, at times working with the CIA. The luck-manipulating villain Amos Fortune tried to use the Atom in a plot against the Justice League, but the Atom helped thwart the plan and became one of the earliest non-founding heroes to join the team. The Atom also had several adventures involving time travel, including facing the villain Chronos and helping his colleague Professor Hyatt conduct experiments with the Time Pool, a tiny portal that provided access to other eras. The Atom frequently teamed with Hawkman and Hawkgirl, becoming good friends. He also met the Golden Age Atom on a few occasions. Ray became one of the first members of the Justice League to marry when his longtime girlfriend, lawyer Jean Loring, accepted his proposal.
After years of Ray and Jean growing apart due to him being on missions as the Atom and her being busy with work, Jean fell in love with a work colleague, Paul Hoben. Before they could take steps to save their marriage, a research flight Ray was on in the Amazon jungle crashed. Ray was presumed dead, but in reality, he had been trapped at a height of six inches (the size he shrank to trying to survive the crash) due to an electric jolt. Ray was captured by tiny aliens, the Katarthans, who'd been trapped on Earth. Ray allied with a resistance force against the cruel leader and developed romantic feelings for Princess Laethwen. In a final battle for the palace, an ancient star-drive was activated and, because it was powered by a white dwarf star fragment, caused Ray to grow to his normal size.
Returning to Ivy Town, Ray discovered that Jean believed him dead and was seeing Paul. Revealing he too loved someone else, Ray and Jean officially divorced, and he returned to the jungle, shrinking to return to Laethwen, whom he eventually married. However, when Jean was cleaning out Ray's equipment, she accidentally shrunk herself. Unaware of how to restore her size, Jean had Ray's biographer lead her and Paul to Ray. But they were captured by rebels loyal to the old regime. Ray saved them and gave Jean an old size-changing belt should it be needed. Ray lived happily with the Katarthans for years, occasionally returning to aid the Justice League, until a wildfire tragically wiped out the Katarthans and their village while he was away. Grief-stricken, Ray returned to Ivy Town.
Ray and Jean, who had divorced Paul, became friends again, though Ray felt it best they not try to rekindle their romance. Little did Ray know that the mental instability Jean had suffered due to trauma from an earlier adventure had returned. Jean forged a plan to force Ray closer to her by killing Sue Dibny, wife of the Elongated Man, using Ray's old size-changing belt to enter Sue's ear and obstruct blood flow to her brain. She hired Captain Boomerang to kill Jack, the father of Robin (Tim Drake), and gave Jack a gun to kill Boomerang, hoping Boomerang would be blamed for Sue. But Ray discovered the truth. Jean was committed to Arkham Asylum while Ray, in despair, shrank into a subatomic realm and vanished. For a time, he was replaced as the Atom by a former correspondent, Ryan Choi.
Ray spent time as a protector of the Multiverse before returning to aid his friends against the attack of undead Black Lanterns, which included Hawkman and Hawkgirl, as their cycle of endless life and death made them susceptible to the Black Lantern rings. Ray became an Indigo Lantern due to his strong compassion and helped the White Lanterns resurrect the Hawks. He later avenged the apparent death of Ryan Choi at the hands of Deathstroke. However, Ryan had survived by projecting his consciousness into the dimension where the Atoms shift their mass when they shrink. Ray helped Ryan create a new body and return to physical form. Today, the two Atoms work both together and separately to benefit the world as members of the Justice League.

Tier explanations
S+The absolute best champions — meta-defining and dominant in every game mode.
STop tier characters that make an impact in every game mode.
A+Top tier in one or some game modes, but not all.
AGreat champions that, while not top tier, are still very good in many situations.
BSolid middle of the road champions — don't particularly excel anywhere but still overall good picks.
CChampions that excel in the early game but perform considerably worse later on. Also champions that have a well defined niche but don't particularly stand out outside of it, so they aren't worth building unless you have a developed roster.
DChampions that fail to have meaningful impact in any content.
