History's Greatest Villains

The villains floating in space.

"History's Greatest Villains" is Zapp Brannigan's label for the personalities of Attila the Hun, Evil Lincoln, Jack the Ripper and Professor Moriarty.

During an incident with the Holo-Shed upon the Nimbus, these figures came alive and caused mayhem on the bridge.

Zapp Brannigan sent them afloat in outer space when he shut a hole in the hull, despite Attila the Hun's concerns.

A similar incident occurred in the Star Trek: The Next Generation episodes "Elementary, Dear Data" and "Ship in a Bottle". They also included Professor Moriarty.
