Changes

* Other Leviathans - Leviathans can be killed by another Leviathan eating them. A Leviathan can even eat ''itself'', a process referred to as "bibbing."

* Rigid hierarchy - The Leviathans rely heavily on having [[Dick Roman|one all-powerful leader]] to give them instructions and conduct their master plan. If he dies, they fall apart completely and revert to a state of disorganization.
