History
There isn’t much information about the Weapon Devils before they are fused with their respective human, with very little information provided by Makima. The Weapon Devils once fought alongside the Four Horsemen against Pochita, but at the height of the battle, Pochita vanished and is reduced to a completely changed, near-death state and ended up on Earth.

The Weapon Devils also somehow ended up on Earth, whether it's because they were killed in the battle and reincarnated or not is unknown. They later become fused with different humans all throughout the world, thus creating 7 new hybrids.
