Knockout

A Knockout occurs when a character's Health reaches zero in a match. They are "knocked out" and permanently removed from the match. However, most team-wide passives, such as Harley Quinn/Arkham and Killer Frost/Prime's passives, will continue to take effect.

Characters who benefit from knocking out enemies include Doomsday/Regime, Doomsday/Prime, Deathstroke/Prime and Deathstroke/Insurgency. Zod/Prime is the only character to benefit from any teammate being knocked out. The second part of Harley Quinn/Arkham Knight's passive triggers when any The Joker character is knocked out, giving her full power.
