Physical description

Neptune is a dark blue alicorn with a mane and tail made completely of flowing water and orange eyes. Her cutie mark is an ocean wave with a trident. She wears a crown decorated with sea shells and tan colored horseshoes. Unlike her sisters, Neptune also has bright aqua-green fins on her legs. She is always seen with her golden trident.


Unlike her two younger sisters, Neptune is very strict, cold and serious and often prefers solitude. She rarely shows any emotion and often speaks in a very blunt manner, which can come off as rude and arrogant to others. She expects nothing less than perfection and does not like putting up with incompetence. Despite this emotional aloofness, Neptune holds a great deal of concern and care for her kingdom and its people.
