He stands at a reasonably tall 6'0 and has an athletic build due to his interest in the more aggressive approach of magic (i.e. Defense Against The Dark Arts) and his interest in sport. Due to his Hellenic origin, he has light, olive skin and brown-green eyes. His dark brown hair is cut quite short, in means to increase practicality.
In School: Flipendo (Knockback Jinx)
At Home: Using his Animagi form (Falcon), which he is not allowed to use at Hogwarts- however, his grandparents allow it within the restrictions of their farm.

Nico was born to a single-mother named Isidora Katsaros, a half-british, half-greek witch who worked as an Auror for the Greek Ministry of Magic. Nico spent the first year of his life in Athens, Greece, but when his mother was sent on duty to England to help the British Ministry of Magic fight Voldemort's ever-amassing army, Nico was put in to the care of his grandparents who lived and worked on a South Yorkshire farm. Both of his grandparents were ex-Aurors, who were long retired.
Nico spent very little time in England before news was received that his mother had been killed by a death eater- of course, only a small child, Nico was oblivious to this and accepted the farm as his home. Life fell in to a cycle- a tiring one, but a one that Nico enjoyed. In the morning he would help his grandfather with the farm before heading out to school- in the afternoon, he would work some more, and, sometimes, his grandfather would teach him magic.
From a young age Nico's grandfather knew of his power, so, for Nico, having magic in his blood was just everyday life. His grandfather, an Animagi, often showed Nico his power, and even taught him the basics, which the boy failed to master, but on his 11th birthday, he learned that everything would change, as magic would change from a hobby to his full-time focus- he received a letter from Hogwarts.
Initially, he was exited, and his grandmother supported the school, as that was where she had went- but Nico's grandfather was not so enthusiastic- he said that Hogwarts was a hypocritical school- a school that would not allow advanced magic (such as an Animagi's magic) but one that was constantly surrounded by danger- this led to Nico joining the Durmstrang Institute instead. Nico did not like Durmstrang, as he did not get a chance to go home on holidays, other than the summer.
Nico spent three years at Durmstrang, learning and perfecting his Animagi form- a falcon. However, at 14, he believed himself to be old enough to defend himself from the dangers of Hogwarts, so, reluctantly his grandfather allowed him to transfer to the Scottish school, which, so far, Nico has preffered.
Nico does not know if he is Pure or Half-Blood, as he does not know his father's identity.
Nico is quick-witted and suave. He likes to think he has a good sense humor, and, because of this, he has, in the past, got in to a considerable amount of trouble for 'messing around' in classes. He can make friends quite easily, as he has the confidence to speak up unlike some of the more reclusive types who sit alone in the library.
He, generally, is quite a friendly person and will welcome company of any kind, though, sometimes, he can come in to conflicts where his personality changes completely, for example, he can get very aggressive and stubborn if he is involved in a fight, or he is insulted. He is very loyal to his friends, and will often stick up for them even when it's maybe not the best idea.
He is quite talented at Quidditch and plays as a Keeper.
He is one of the few, if not the only, hogwarts student who is an Animagi. Pet- Has a large Maine Coon cat named Poseidon. Boggart- Voldemort and his Death Eaters Patronus- Falcon Worst Fear- Death Eaters, Voldemort
