23 years old, Cornelius has brown eyes and short brown hair. He wears a dark brown jacket over an open-collared white shirt with brown buttons and a mauve striped tie, along with donning an oil stain on the left side of his shirt. Additionally, he sports golden gear and wrench brooches.
Heir to the illustrious Osborne family, Cornelius has to deal with the struggles of his name, along with fitting in with the strict rules of being an aristocrat. Due to this, Cornelius has developed a rebellious side and isn't good with authority. Instead of the life chosen for him by his surname, Cornelius wants to forge his own path by following his passion of inventing, something on which he and his overbearing parents quarrel on. Despite this, Cornelius is very loyal to the police department and will help out when he's needed.
