Captain Napolipolita is a female member of the Alpha Cygnan space navy who has spent sixteen years searching for C-ko throughout the universe. Despite initially appearing as a man due to her all-female race, she cuts an impressive figure with her impeccably dressed appearance and dramatic cloak and sunglasses. However, Napolipolita's facade crumbles when danger arises, revealing her addiction to alcohol. After the events of the first movie, Napolipolita is stranded on Earth, unable to return home to Lepton Kingdom. She rebuilds her grounded spaceship into a 30,000-room hotel for Earthlings, but remains miserable and longs only to go back. In the final A-ko movie, she misses her chance to return due to getting drunk on the way to Graviton City High School for Girls, where the Alpha Cygnans were landing.
