Radiation is one of the possible challenges (commonly called "handicaps" due to the confusion with Challenge Mode) encountered in standard or challenge mode battles.

The character you currently have tagged in would constantly lose a small percentage (usually 1%) of their maximum health every second. Bleeding characters will take 20% more damage per stack of bleed (e.g. with 1 bleed running and with a 1% raditaion, they would lose 1.2% health per second to radiation).

Aquaman/Prime's Atlantean Hero is immune to Radiation. Martian Manhunter/Blackest Night's passive halves Radiation damage like all other forms of damage while his defense buff is active. Blocking while Radiation is active will count toward's Wonder Woman/Prime's passive, despite that the damage is not reduced.


  • LexCorp Set's full set's effect is sometimes referred to as "radiation", due to its similar effects.
