INSTANTLY overload with polarized radianite energy that pulses from KAY/O in a massive radius. Enemies hit with pulses are suppressed for a short duration. While overloaded, KAY/O gains combat stim and can be re-stabilized if downed.
— In-game description

NULL/cmd is an ultimate ability for KAY/O.


NULL/cmd is primarily an Empowerment and Suppressant ability that KAY/O can instantly activate to begin briefly winding up, after which he becomes overloaded and emits a pulse that suppresses any enemy agents within range. For the duration of the ultimate, KAY/O gains a combat stim and will continue to periodically emit more suppressing pulses from his location.

If KAY/O would be killed during NULL/cmd he is downed instead and enters a destabilized state, giving him increased HP and a countdown which will cause him to be killed if it completes. Any remaining suppression pulses that KAY/O would have emitted had he not been downed will still be produced in this state but he will not produce any more pulses after this. Whilst downed, KAY/O can also see what is happening in front of him but is unable to equip anything or move his field of view. His minimap is also obscured and his audio dampens as the countdown gets low. Allies can stabilize his core to pause the countdown and, after a few seconds of channeling, revive him. KAY/O revives with up to 100 HP, based on the percentage of HP he had remaining from his downed state when he was revived, with no shields.
