When Lilith Mother of all Demons was freed from Leviathan, her mystical prison, and summoned her Lilin, their presence weakened the dimensional fabrics and this led to a reality rip to occur in Phoenix, Arizona, in a rundown building basement. This rip allowed a hive-minded bacteria known as the Viral Swarm to enter Earth-616. In the Viral Swarm's home world, they were the dominant life-form as they had fed on and consumed all other living beings. The Viral Swarm, seeing the reality rip into Earth-616, saw this as an opportunity for new life energy to feed on.
The basement in Phoenix, Arizona was being used by several homeless people as a shelter. The Viral Swarm bacteria separated and in doing so found amongst the various homeless people individual hosts. this particular part of the hive bacteria would enter a male and transformed himself into the being known as Tokamak.
