Nicolaus Copernicus is some guy who lived in Poland who bragged about the Sun being at the center of the Solar System and universe, but then a bunch of Catholics threatened to set him on fire, but rebelled against them.
Later he fled from Poland after Po, the other Teletubbies, Megatron, and their allies went after Nicolaus Copernicus himself.
He was later banished by Chin-Chin for "not giving him chromosomes".
Element 112 was named "Copernicium" (Symbol: Cn) in honor of him.
