A robot from an alternate future, KAY/O was created by the humans of that time to fight back against the radiants that they were at war with. Using the power of polarized radianite, KAY/O proved effective in shutting down radiants' abilities, making them easier to eliminate. The radiant Reyna was of particularly high importance to KAY/O for her actions against humanity, and KAY/O was able to eventually eliminate her. However, at this point humans had already suffered severe losses.[1]

KAY/O would later on travel centuries back in time to the present day, arriving on an island near the Caribbean, and would soon be recruited as an agent of the VALORANT Protocol. He now fights as an agent in a time where there is harmony between humans and radiants, alongside alternate versions of both humans he served with and radiants he fought against. However, the scars from KAY/O's previous war remain, from the losses he endured and from the pain inflicted by versions of the same radiants he now finds himself working with.


  • KAY/O is created by the humans of an alternate timeline to fight against Radiants in their Human-Radiant War.[2]
    • Fights alongside Brimstone and Sova.[3]
    • Fights against Astra, Reyna, Sage, and Skye.[3]
  • KAY/O is eventually able to kill Reyna, a major part of the Radiant forces.[4]
  • KAY/O decides to leave his time to travel back.


  • Recruited as its seventeenth agent.

The Blackmailer[]

  • KAY/O is assigned as a member of the Istanbul strike team.[8]
    • KAY/O's role was to run aerial surveillance from the Vulture and oversee the mission.
    • KAY/O takes it upon himself to apprehend the target when they attempt to escape whilst the Ground squad is preoccupied, jumping out of the Vulture to ground before incapacitating the target with a suppressive pulse.

Continuing the Omega Project[]

  • KAY/O is part of a team that scouts the layout of α-Lisbon in preparation for their journey to Ω-Lisbon[9]

First ventures into Omega[]

  • KAY/O contacts Brimstone to apologize about being unable to distinguish the Protocol leader from memories of his own Brimstone from his previous timeline.[10]

Project Landfall[]

  • KAY/O lets Killjoy study his polarization core, additionally receiving some general maintenance.[11]
  • After Brimstone contacts him about doubts he was having over having betrayed Kingdom and K-SEC with their mission to shut down Landfall's interverse portal, KAY/O assures him that he was only protecting Kingdom from itself, and that the mission had been a complete success.[12]

Scions of Hourglass[]


   "We have one job; save this Earth. No excuses"
— KAY/O (Match Start)

Though he is a robot, KAY/O is not particularly devoid of human emotion. He came to Earth as a veteran who has seen the terrible spoils of war, and he fights determined so that a conflict of similar proportions will not happen ever again. Given his affiliation in the Human-Radiant War, he has shown to be more amiable towards his human teammates, while being wary around radiant allies.

He has been known to make a lot of quips and sarcastic remarks while he charges into battle, showing that he is more than just his program as a killing machine.


His face is a screen that displays different images based on what is happening. When he speaks, a peak meter is animated. KAY/O's body, arms, and head are made of metal. His legs are made out of what appears to be a combination of metal and leather. Parts of his body have electricity and energy visible, these parts include his forearms, the middle of his chest, and the sides of his legs.
