A person that is the biggest and baddest ninja you will ever meet in your entire life.
No example, because anyone who could possibly make one is killed by the Sebastian ninja.

A Sebastian is someone who is loved by all. He never fails to put a smile one your face whenever you need it. Sebastians usually tend to play soccer. They are very athletic, sweet, kind, funny, gorgeous, people with a fantastic sense in clothing. They always have a great sense of humor, a hilarious laugh, and a perfect smile. All the girls want him and all the guys want to be him.
Ooooo look at that gorgeous boy, that's got to be a Sebastian.

A caring guy who's pretty passive and doesn't always know how to express his emotons hence he comes off as being cold, selfish and uncaring. A loner. He's got a strange charm that draws people to him although he probably isn't the nicest person you'll ever meet. Depending on your personality, you'll like him even more for keeping you on your toes.

If you're interested in him you must have tons of patience and be willing to "put up" with him because he is a self professed stoic and mediocre boyfriend who leads a busy life but at times would rather spend time alone than be out in the world dealing with other people.

He's honest, focused, self reliant, romantic, sarcastic as hell and has a hard time trusting people

Loves: his cat and riding bikes
Hates: being tickled
-Whatever you do, don't tickle Sebastian.
-Why?
-Because he will punch you in the face

Probably the most lovable, bubbly, kind, caring and all around good person that you will ever meet. He has so much love to give people and will never seize to let anyone down. He is strong and loyal and will always be there for the people he loves. He is so funny he can make everyone laugh just by being around him. Despite his troubles in the past he will always be a shoulder for someone to cry on. The way that he looks at people can make them feel wanted even when they are going through such a rough patch in their life. He loves sports and animals. He sometimes can act like a huge dick around large amounts of people but when he is with his close friends he is nothing but an angel towards them. Sebastian is a very popular person who is a really good people’s person and he is incredibly smart. He can sometimes be an asshole towards his teachers when he doesn’t mean to be. Sebastian will light up your life on your darkest day. He has a unique sparkle in his eyes that is so rare that you will probably only see once in your life. He is probably one of the most handsome people that you will ever meet. His smile is so bright and beautiful that you would probably never see anything like it again. He also has incredibly soft and gorgeous hair. He is like the many stars in the galaxy because without them there wouldn’t be any light or happiness.
H: I love him so much, he is my Sebastian
