9/22 - Instant Death! 300 points. If a Critical Hit is rolled (and the Damage Value for the attack is greater than 0), Damage Dealt will KO the target. If a Critical Miss is rolled, the attacker is KO'd. In the case of Support: a Critical Hit fully heals the target and a Critical Miss KO's the target as well as dealing 1 unpreventable click of damage to the figure with Support.
Just for clarification, a Critical Hit will NOT KO a figure from "splash" damage of an Energy Explosion, nor will it KO a figure from Mind Control. It will only KO a figure from Incapacitate if Stunning Blow is in effect.
A figure may still avoid damage in the usual ways (Impervious, Super Senses). Powers that reduce damage will not prevent the KO from a Critical Hit.
