"Uh oh, you really made an ERROR in your defense tactics HAHAHA"

— Exo 404

Exo 404 is an Exo who was able to betrayed the guardians and obtained the power of the darkness, he is on nobody's side and already has a kill count, this person has a bounty on his head for all sides.

He seems to go in hiding for awhile but then he comes back out in the second collapse to give the Shadowkeepers a new problem to deal with.

At some point in time after the Collapse, he would be recruited by the Overtakers as a weaponized virus that would help their commanders launch an assault against Mallory's doppelgangers.
