Emperor Nikolai is the rich and eccentric robot emperor of the Robo-Hungarian Empire, described by President Nixon as "an insane dictator and a heck of a bowler". In an interview with journalists Nikolai described himself as "just a humble emperor, with a big, big crown!" In truth, Nikolai had grown tired of his life of authority and riches and yearned to experience life as a normal commoner.
Emperor Nikolai visited New New York in 3010 to give a speech at the United Nations. He arrived with his entourage aboard his extravagant caviar-powered yacht RMS Overkill which would serve as his residency during his time in the city, were it not for his encounter with Bender who was trying to rob him of his big, big crown. Bender, whose mind was in the body of Amy Wong, convinced Nikolai to trade bodies with him so that Emperor Nikolai could finally experience life as a lowly bending unit while, perhaps more importantly, Bender could enjoy life as a fabulously wealthy and influential emperor, while also agreeing to fill in for Nikolai at a speech to the United Nations General Assembly.
