Atom

Quantum's Take

Atom is a Legendary Warrior Champion who does Physical damage. Atom is best used in Training Simulator, Story Mode. 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.
