The Dubinater was a time-traveling killing machine created by CurtSibling. It bore a striking resemblance to George W. Bush. In DRAW Your Own Story 1, its purpose was to eliminate whatever mod was trying to control the thread. The Dubinater once attempted to kill Chieftess as an infant, with disastrous results. Defeated, it traveled back to DYOS 1's present, where it was eventually destroyed in the Perfection-CivGeneral cataclysm. Its next target: 2011 CivGeneral!
Since the Dubinater was destroyed at a set period in time, this implies that it escaped death in other historical events. If it is ever encountered again, it is almost certainly indestructible. Maybe.
