|Book debut||Arthur Rocks with BINKY|
|Cartoon debut||"Meet Binky"|
Nero is the drummer of BINKY. He is later revealed to be a hologram. Despite not being real, his character model has been reused on occasion for a background character. His name was only revealed in the novelization of the episode.
Nero is an anthropomorphic aardvark with a cream complexion. He wears a gray V-neck T-shirt with a black collar, a blue collar shirt over the T-shirt, black sweatpants with white stripes, and red-and-white sneakers. He has blond, shoulder-length hair.
- Although Nero is male, he is often mistaken as a female because of his long hair and unusually high voice.
- When the limo goes out of control, Nero is accidentally given Kyra's voice. His proper voice returns after the limo stops.
