Nicholas Loureiro is a main antagonist in the High School Years and Forever Sophomores series. He is Willy's arch nemesis, and he has been ever since he stole his popularity in "The Retard Bully". He debuted in "High School Begins".
Nick is rude, selfish, and manipulative. He is always mocking Willy for his messy hair, unshaved beard, and his habit of walking on his toes. Willy used to be popular in freshman year, until Nick jumped in and took his popularity away in retaliation for making fun of his mother. Since then, all of Willy's friends have been treating him like an outcast. Whenever Willy tries to be cool, Nick would always turn him down by telling him that what he's doing is "too far". He even took full credit for the roasts Willy found on Pinterest. He is also shown to be a troublemaker in class. For example, he would always slap other kids in the neck, spend too much time in the bathroom, and of course, humiliate Willy or try to get him in trouble. He has been appearing in almost every episode since his debut in "High School Begins".
Nick has fair skin, brown eyes, and brown hair. He is often seen wearing a light gray hoodie with a long or short-sleeved undershirt of varying colors(usually black, white, maroon, blue, gray, or yellow)., black, white, or gray sweatpants or shorts(sometimes khakis), and navy blue sneakers. Starting at season 23, his sneakers are black.
