Metatron 1, a neutron angel, is a prime angel and God's scribe. No angels remember the gods, save Metatron. Unlike most angels, Metatron wears his armor in the Void (or uniquely has skin that looks like stone and is bleeding birds).
After Zoss shattered the bodies of the primes, he chased their souls to the Void and learned of Metatron 1. He killed the rest of the primes, but left Metatron 1 alive to torture the 777,777 names of God out of him and create the Keys of Kings. Unlike all other angels, Metatron never died.
While crippled, he founded the Holy Thorn Knights to sterilize Throne, something that they still want to do, though he later saw the error in this and decided to turn Zaid as The Successor into a new singular ruler of heaven, this time someone worthy of taking the place of YISUN.
Currently, METATRON LIVES motionless on the edge of the field of dead prime angels that are awaiting reincarnation, next to a platform that the Thorn Knights meet at. Though crippled, he seems to be able to move his head and eyes, as well as speak.
