For XMarvelous_MarvelX 's 'Under the Sea' selection, I asked to be a prince, and was accepted. So here is his royal highness, one of the princes of the sea

Name: Fen Poseidon Douglas Seawater
Nicknames: Son of the sea. Your highness. Future king. Fenny, only by his family is he allowed to be called that.
Age: 20. (I kinda want him to be the eldest son, future king.)
Gender: Male
Sexuality: Bisexual, but leans towards women.

Appearance: Fen has eyes the colour of the ocean itself. Hair that looks like waves sand, that reaches just past his shoulders. His facial features are sharp, always making him look serious. The only thing is, he doesn't have ten fingers, but eight. Len doesn't have a pinky finger on either hand. His tail is stormy grey, with faint slashes of gold you can barely noticeable, but if you look long enough, you'll see it.

Personality: Fen has always acted like a king should, even before his mother started to train him to be so. He has a sense of humour, but you won't see him on the side of telling jokes often. Unless you are the funniest being in the seven seas, he'll only scoff as a laugh. He won't grovel at your feet for anything, unless it's for the wellbeing of his family. Some people think he's not fit to be king because of his missing fingers, but oh-boy are they wrong. Even his mother says he might be a better ruler than her, but he doubts that. Diplomatic, calculating, sharp as a spear, and just. Fen will try to use his words first, but if not, violence is the answer. He almost never pulls out the prince/future king card, cause that almost never works.

Likes: His family. Justice. Knowing he'll be king one day. Music, playing the violin (Even if it defies logic of water). His brothers and sister. Battle training. The idea of the selection. The palace. His hands, even if missing a couple fingers. People making the first move on him (Hint, Hint).
Dislikes: People who think they know him. Discrimination against him or his family. Being criticized for his lack of ten fingers. The nickname from his family. Injustice. Being treated like he's a ignorant or an idiot. Girls who are clingy or crowd around him. Having to repeat himself. The word 'dehydrated', the word makes him cringe.

Family: His mother, his father, his younger three brothers and sister
Background: Fen grew up in the palace with his family. He was the eldest son, so he was always treated with respect. He stayed by his mother's side during his childhood, watching what she did and said. When he was 8, his training actually started for him to become a king.
Other: Fen unknowingly sleep-swims and sleep-sings. If you followed him, you'd know he has a good voice.
