Nick Vermicelli is a fictional character in Hey Arnold!. He is one of Big Bob Pataki's business associates turned enemy and Scheck's accomplice; that is to say, he is the hidden secondary antagonist of Hey Arnold! The Movie.
Nick has a unibrow, though it is thicker and brown and a thin mustache. He has long shoulder length brown hair tied back into a pony tail and wears a gray suit. He is Italian-American.
Nick Vermicelli seems to be Bob's business advisor, as in "Runaway Float", he criticized the kids' wanky land float for not representing the Beeper company properly. He proposed the idea to cover the float with a giant paper mache beeper. Nick's plan failed miserably when Bob lost control of the new bulky and awkward float and ended up almost killing himself, Nick and all of the children on the float. Luckily Arnold intervened by catching up to the float on a borrowed bike, climbing behind the wheel of the old car the float was built on, and yanking the handbrake.He was the secondary antagonist of the movie, where he became Mr. Scheck's associate. After Big Bob finds out that he has been tricked by Vermicelli into signing an unfair contract that would give Scheck 51% ownership of the Beeper Emporium, Bob furiously storms into Nick's house and the two get into a fight. During this fight, Bob gets covered in pickle juice and winds up looking like the Incredible Hulk. Bob loses that fight when Nick knocks him out by slamming the refrigerator door on his head. At the end however, upon witnessing Scheck getting arrested, Bob spots Nick trying to escape to his pickup truck. Bob bodyslams Nick into his truck. Nick nervously attempts to try to make it up to him, but Bob won't have any of it and knocks him out with one punch. It is unknown what happens to Nick after this, though he is most likely to be arrested for his betrayal and his part in Scheck's plan.
