Brash 5

Brash 5 is element in the zombies story that has no real origins as it was created in a time loop in the original timeline. In July 2013, Dr. Josh Istag attempted to recreate the element and eventually was successful. The element then rapidly multiplied and spread across the earth, past, present, future and alternate unvierses. The element is blue and can change from liquid to solid and gas.
