During the early months of year 2009, 12 X5's escaped from a facility called Manticore in Gillete, Wyoming. The escape was prompted by the unit C.O. Zack, known to the rest of his unit as Zack. Along with Zack were Max Guevara/X5-452, Tinga/X5-656, Brin/X5-734, Ben/X5-493, Syl/X5-701, Krit, Jondy, Zane, Seth, Vada, and Kavi.
The group, led by Zack, broke out of Manticore and fled into the forest surrounding the facility. After rendezvousing in a clearing a safe distance from the building, Zack split the group up and sent them in different directions.
