Though security is usually tight within the prison, a riot took place days after the arrest of the Destructix when they attempted a breakout. During the chaos that followed, inmates Verti-Cal and Horizont-Al were freed of their Control Collars, unleashing their destructive demigod forms which inflicted severe structural damage to the prison as well. Eventually the situation was contained by prison staff and officers arriving as backup, but the Destructix succeeded in escaping along with Scourge as they had planned. In the end, more than 60% of the cell blocks were left damaged, forcing the prisoners to be housed in temporary shelters in the exercise yard. The repair efforts put into effect also resulted in costly diversion of needed resources by the Zone Cops. (SU: #31, #32)
