Nicolas Fábián Mihalios (born 19 August, 1997) was a half-blood Hungarian wizard and eldest child of Alex and Nadia Mihalios (née Nagy). He has twin siblings, Mateo and Franciska, and is the godson of Marton and Julianja Nagy. He attended Corvinus Academy of Magic from 2007 to 2008, but he was picked on in school for his relation to his uncle Nicolas, who, in addition to being kicked out of the school for physical violence, had controversially burned the Corvinus flag after defeating the school in a Quidditch match in Romania. Nico was unwilling to deal with it and requested his parents to transfer him to another school. After learning Romanian during the summer from Mateo Maximoff, his father's best friend, Nico began attending the Carpathian School of Magic on the 11th of September.
